Instructor’s Manual

INTRODUCTORY COMMENTS Purpose of this Manual The purpose of this manual is to facilitate the use of the text by the Instructor. It contains the detailed outline of each chapter, lecture guides with suggestions on how best to present the material in each chapter, the answer to the end-of-chapter problems, and a set of 12 to 18 multiple-choice questions with answers for each chapter.

Course Outlines The text includes more material than can be covered in a one-semester undergraduate course in international economics, thus providing the Instructor with a great deal of flexibility as to what to include.

The core chapters for a one-semester undergraduate course in international economics are: Chapters 1-6, 9, 13-18, 21. I would cover each of these 14 chapters in one week (except for doubling up in one week) of the semester. I would skip the appendices, or make some of them optional. I would give the midterm after Chapter 9 and the final on all chapters covered at the end of the semester. Some Instructors, of course, may want to follow a different format.

In an undergraduate course in international trade, I would cover Chapters 1-12, and 21.

In a one-semester undergraduate course in international finance, I would cover Chapters 1, 13-21.

In a graduate course in International Trade in the MA, MBA, International Affairs, and International Political Economy, I would cover Chapters 1-12, and 21. I would also cover all the appendices and assign readings from the selected bibliography at the end of each chapter.

In a graduate course in International Finance in the MA, MBA, International Affairs, and International Political Economy, I would cover Chapters 1 and 13-21. I would also cover all the appendices and assign readings from the selected bibliography.

In a graduate course in International Economics, I would cover all 21 chapters, with or without the appendices and other readings from the selected bibliography.

Instructor’s Manual

Content of this Manual The lecture guide given in this manual is specifically designed for a one-semester undergraduate course in international economics.

The questions for review at the end of each chapter involve only recall of what is clearly explained in the text. Their function is simply to emphasize those concepts and theories that the student needs to learn and remember. I would encourage the student to go over them on his own and check his answers in the text.

I would assign the problems at the end of each chapter. These are challenging but not tricky or very time consuming. They are intended to enlist the active participation of students so as to make international economics truly come alive.

The multiple-choice questions included can be used for quizzes or to be part of the midterm and final examinations. The Instructor who feels that more questions and problems would be useful can consult my small and popular paperback Theory and Problems of International Economics (4th ed., 1996) in the Schaum's Outline Series, which includes a wealth of additional multiple-choice questions and solved problems and to the Study Guide prepared for this text by Professor Arthur Raymond of Muhlenberg College. At the end of each of the four parts of this Manual, there are also additional essays and problems with answers that can be used for class exams.

A Personal Note to You, the Instructor I welcome any comment, suggestion, or opinion that you may have on the use of the text.

You can correspond by e-mail directly with me or through John Wiley, and I will personally acknowledge your letter and comment on your suggestions. I will, of course, consider your comments for the next Edition of the text and would gratefully acknowledge any such contribution.

Lecture Guide 1.

As the first chapter of the book, the general aim here is to define the field of study of international economics and its importance in today's interdependent world.

The material in this chapter can be covered in two classes. I would utilize one class to cover Sections 1 to 3 and the second class to cover Sections 4 to 6. I would spend most of the second class on Section 3 on the major current international economic problems facing the United States and the world today and to show how international economics can suggest ways to solve them. This should greatly enhance students' motivation.

Answer to Problems 1.

a) International economic problems reported in our daily newspapers are likely to include: • • • • • • •

Slow growth and high unemployment in advanced economies; trade controversies between the United States, Europe, Japan, and China; excessive volatility of exchange rates; huge and unsustainable trade deficits of the United States; structural unemployment in advanced economies and insufficient restructuring in transition economies; deep poverty in many developing nations; resource scarcity, environmental degradation and climate changes

b) The effect of each of the above problems on the U.S. economy are: ● ● • • • • •

stagnant standard of living and economic suffering; increased protectionism and the danger of trade wars; discourages foreign trade and investments; can result in trade protectionism and/or deep dollar depreciation; reduces advanced countries' imports of goods and services from the rest of the world; can lead to political instability abroad that would adversely affect the U.S.; endangers future standard of living in the U.S. and abroad.

c) The effect of each of the current international economic problems can affect each of us, as follows: ● ●

•

(ch01(2))

Can lose job and suffer financial losses; pay higher prices for imported products; great fluctuations in the price of imported products and cost of foreign travel;

can lead you to support demands for trade protection; slower growth of wages and incomes; can lead to higher taxes to help poor countries; can result in higher taxes and price of fuel and other products.

a) Five industrial nations not mentioned are: France, Italy, Spain, Sweden, and Austria. b) See Table 1A. Note that, generally, smaller nations have higher percentages of imports and exports to GDP. The exception is Spain, which though economically smaller than Italy, has a smaller percentage of imports and exports to GDP than Italy.

Trade between the United States and Brazil is much larger than trade between the United States and Argentina. Since Brazil is larger and closer than Argentina, this trade does follow the predictions of the gravity model.

a) Mankiw’s Economics (6th., 2011) includes the following microeconomics topics: • • • • • • • • • • •

b)

(ch01(2))

The market forces of demand and supply; elasticity and its application; the theory of consumer choice; consumers, producers, and the efficiency of markets; the costs of production; firms in competitive markets; monopoly; oligopoly; monopolistic competition; markets for the factors of production; the demand for resources;

Just as the microeconomics parts of your principles text deal with individual consumers and firms, and with the price of individual commodities and factors of production, so do Parts One and Two of this text deal with production and consumption of individual nations with nations with and without trade, and with the relative price of individual commodities and factors of production.

c)

Instructor’s Manual

Mankiw’s Economics (6th., 2011) includes the following microeconomics topics: measuring a nation’s income and the cost of living; • • • • • • • • • • •

production and growth; savings investment and the financial system; unemployment and its natural rate; the monetary system, growth and inflation; money growth and inflation; open-economy macroeconomics: basic concepts; a macroeconomic theory of the open economy; aggregate demand and aggregate supply; the influence of monetary and fiscal policy on aggregate demand; the short-run trade off between inflation and unemployment five debates over macroeconomic policy.

d)

Just as the macroeconomics parts of your principles text deal with the aggregate level of savings, consumption, investment, and national income, the general price level, and monetary and fiscal policies, so do Parts Three and Four of this text deal with the aggregate amount of imports, exports, the total international flow of resources, and the policies to affect these broad aggregates.

6.

a) Consumer demand theory predicts than when the price of a commodity rises (cet. par.), the quantity demanded of the commodity declines.

When the price of imports rises to domestic consumers, the quantity demanded of imports can be expected to decline (if everything else remains constant).

7.

a) A government can reduce a budget deficit by reducing government expenditures and/or increasing taxes. b) A nation can reduce or eliminate a balance of payments deficit by taxing imports and/or subsidizing exports, by borrowing more abroad or lending less to other nations, as well as by reducing the level of its national income.

8.

(ch01(2))

a) Nations usually impose restrictions on the free international flow of goods, services, and factors. Differences in language, customs, and laws also hamper these international flows. In addition, international flows may involve receipts and payments in different currencies, which may change in value in relation to one another through time. This is to be contrasted with the interregional flow of goods, services, and factors, which face no such restrictions as tariffs and are conducted in terms of the same currency, usually in the same language, and under basically the same set of customs and laws.

International Economics – 11th Edition

Instructor’s Manual

b) Both international and interregional economic relations involve the overcoming of space or distance. Indeed, they both arise from the problems created by distance. This distinguishes them from the rest of economics, which abstracts from space and treats the economy as a single point in space, in which production, exchange, and consumption take place.

9.

We can deduce that nations benefit from voluntarily engaging in international trade because if they did not gain or if they lost they could avoid those losses by simply refusing to trade. Disagreement usually arises regarding the relative distribution of the gains from specialization in production and trade, but this does not mean that each nation does not gain from trade.

10.

International trade results in lower prices for consumers but harms domestic producers of products, which compete with imports. Often those domestic producers that stand to lose a great deal from imports band together to pressure the government to restrict imports. Since consumers are many and unorganized and each individually stands to lose only very little from the import restrictions, governments often give in to the demands of producers and impose some import restrictions. These topics are discussed in detail in Chapter 8.

11.

A nation can subsidize exports of the commodity to other nations until it drives the competing nation's industry out of business, after which it can raise its price and benefit from its newly acquired monopoly power.

Some economists and politicians in the United States have accused Japan of doing just that (i.e., of engaging in strategic trade and industrial policy at the expense of U.S. industries), but this is a very complex and controversial aspect of trade policy and will be examined in detail in Chapter 9.

12.

a) When the value of the U.S. dollar falls in relation to the currencies of other nations, imports become more expensive for Americans and so they would purchase a smaller quantity of imports. b) When the value of the U.S. dollar falls in relation to the currencies of other nations, U.S. exports become chapter for foreigners and so they would purchase a greater quantity of U.S. exports.

Lecture Guide 1.

This is a long and crucial core chapter and may require four classes to cover a adequately. In the first lecture, I would present Sections 1, 2, and 3. These are short s sections and set the stage for the crucial law of comparative advantage.

2.

In the second lecture of Chapter 2, I would concentrate on Section 4 and carefully explain the law of comparative advantage using simple numerical examples as in the text. The crucial parts here are 4b (which explains the law) and 4d (which establishes the link between trade theory and international finance). I find that the numerical explanations before the graphical analysis really helps the student to truly understand the law. The simple lawyer-secretary example should also render the law more immediately relevant to the student. I would also assign Problems 1-6.

3.

In the third lecture, I would cover Sections 2.5 and 2.6a. I would pay particular attention to Sections 2.5c, 2.5d, and 2.6, which are the heart of the chapter.

4.

In the fourth lecture, I would cover the remainder of the chapter. The crucial section here is 2.6b and the most difficult concept to explain is the shape of the combined supply curve for wheat and cloth. The appendixes could be made optional for the more enterprising students in the class. I would also assign Problems 7-13.

Answer to Problems 1.

In case A, the United States has an absolute advantage in wheat and the United Kingdom in cloth.

In case B, the United States has an absolute advantage (so that the United Kingdom has an absolute disadvantage) in both commodities.

In case C, the United States has an absolute advantage in wheat but has neither an absolute advantage nor disadvantage in cloth.

In case D, the United States has an absolute advantage over the United Kingdom in both commodities.

In case A, the United States has a comparative advantage in wheat and the United Kingdom in cloth.

In case B, the United States has a comparative advantage in wheat and the United Kingdom in cloth.

In case C, the United States has a comparative advantage in wheat and the United Kingdom in cloth.

In case D, the United States and the United Kingdom have a comparative advantage in neither commodities.

3.

In case A, trade is possible based on absolute advantage.

In case B, trade is possible based on comparative advantage.

In case C, trade is possible based on comparative advantage.

In case D, no trade is possible because the absolute advantage that the United States has over the United Kingdom is the same in both commodities.

4.

a) The United States gains 1C. b) The United Kingdom gains 4C. c) 3C < 4W < 8C. d) The United States would gain 3C while the United Kingdom would gain 2C.

5)

a) The cost in terms of labor content of producing wheat is 1/4 in the United States a and 1 in the United Kingdom, while the cost in terms of labor content of producing cloth is 1/3 in the United States and 1/2 in the United Kingdom. b) In the United States, Pw=$1.50 and Pc=$2.00. c) In the United Kingdom, Pw=£1.00 and Pc=£0.50.

6)

a) With the exchange rate of £1=$2, Pw=2.00 and Pc=$1.00 in the United Kingdom, so that the United States would be able to export wheat to the United Kingdom and the United Kingdom would be able to export cloth to the United States. b) With the exchange rate of £1=$4, Pw=$4.00 and Pc=$2.00 in the United Kingdom, so that the United States would be able to export wheat to the United Kingdom, but the United Kingdom would be unable to export any cloth to the United States.

c) With £1=$1, Pw=$1.00 and Pc=$0.50 in the United Kingdom, so that the United Kingdom would be able to export both commodities to the United States. d) $1.50 < £1.00 < $4.00.

a) See Figure 1. b) In the United States Pw/Pc=3/4, while in the United Kingdom, Pw/Pc=2. c) In the United States Pc/Pw=4/3, while in the United Kingdom Pc/Pw=1/2.

See Figure 2.

The autarky points are A and A' in the United States and the United Kingdom, respectively. The points of production with trade are B and B' in the United States and the United Kingdom, respectively. The points of consumption are E and E' in the United States and the United Kingdom, respectively. The gains from trade are shown by E > A for the U.S. and E' > A' for the U.K.

9.

a) If DW(US+UK) shifted up in Figure 2.3, the equilibrium relative commodity price of wheat would also rise by 1/3 to PW/PC=4/3. Since the higher DW(US+UK) would still intersect the vertical portion of the SW(US+UK) curve, the United States would continue to specialize completely in the production of wheat and produce 180W, while the United kingdom would continue to specialize completely in the production of cloth and produce 120C. b) Since the equilibrium relative commodity price of cloth is the inverse of the relative commodity price of wheat, if the latter rises to 4/3, then the former falls to ¾.. This means that DC(UK+US) shifts down by 1/3 in the right panel of Figure 2.3.

If DW(US+UK) intersected SW(US+UK) at PW/PC=2/3 and 120W in the left panel of Figure 2.3, this would mean that the United States would not be specializing completely in the production of wheat.

The United Kingdom, on the other hand, would be specializing completely in the production of cloth and exchanging 20C for 30W with the United States. Since the United Kingdom trades at U.S. the pre-trade relative commodity price of PW/PC=2/3 in the United States, the United Kingdom receives all of the gains from trade.

11.

See Figure 3 on page 15 and the discussion in the last paragraph of Section 2.6b in the text.

12.

a) The Ricardian model was tested empirically by showing the positive correlation between relative productivities and the ratio of U.S.to U.K. exports to third countries and by the negative correlation between relative unit labor costs and relative exports b) The Ricardian trade model was confirmed by the positive relationship found between the relative labor productivity and the ratio of U.S. to U.K. exports to third countries, as well as by the negative relationship between relative unit labor costs and relative exports. c) Even though the Ricardian model was more or less empirically confirmed we still need other models because the former assumes rather than explains comparative advantage (i.e, it does not explain the reason for the different labor productivities in different nations) and cannot say much regarding the effect of international trade on the earnings of factors of production. d) The United States has a comparative disadvantage in the production of textiles.

Restricting textile imports would keep U.S. workers from eventually moving into industries in which the United States has a comparative advantage and in which wages are higher.

Lecture Guide 1.

In the first lecture of Chapter 3, I would cover Sections 1, 2, and 3. Section 2 can be covered quickly, except for 2b, which requires careful explanation because of its subsequent importance. Careful explanation is also required for 3b. I would assign Problems 1 and 2.

2.

In the second lecture, I would cover Sections 4, 5a, and 5b. This is the basic trade model and it is essential for the student to master it completely. To this end, I would assign and grade Problems 3 and 4.

3.

In the third lecture, I would cover the remainder of the chapter. The topics here represent elaborations of the basic trade model. I would assign problems 5, 6, and 7 and go over problem 7 in class even though its answer is also in the back of the book. I would make the Appendices optional for those students in the class who have had intermediate micro theory.

Answer to Problems 1.

a) See Figure 1. b) The slope of the transformation curve increases as the nation produces more of X and decreases as the nation produces more of Y. These reflect increasing opportunity costs as the nation produces more of X or Y.

2.

a) See Figure 2.

We have drawn community indifference curves as downward or negatively sloped because as the community consumes more of X it will have to give up some of Y to remain on the same indifference curve. b) The slope measures how much of Y the nation can give up by consuming one more unit of X and still remain at the same level of satisfaction; the slope declines because the more of X and the less of Y the nation is left with, the less satisfaction it receives from additional units of X and the more satisfaction it receives from each retained unit of Y.

c) III > II to the right of the intersection, while II > III to the left.

This is inconsistent because an indifference curve should show a given level of satisfaction. Thus, indifference curves cannot cross.

3.

a) See Figure 3. b) Nation 1 has a comparative advantage in X and Nation 2 in Y. c) If the relative commodity price line has equal slope in both nations.

4.

a) See Figure 4. b) Nation 1 gains by the amount by which point E is to the right and above point A and Nation 2 by the excess of E' over A'. Nation 1 gains more from trade because the relative price of X with trade differs more from its pretrade price than for Nation 2.

5.

a) See Figure 5. In Figure 5, S refers to Nation 1's supply curve of exports of commodity X, while D refers to Nation 2's demand curve for Nation 1's exports of commodity X. D and S intersect at point E, determining the equilibrium PB=Px/Py=1 and the equilibrium quantity of exports of 60X. b) At Px/Py=1 1/2 there is an excess supply of exports of R'R=30X and Px/Py falls toward equilibrium Px/Py=1. c) At Px/Py=1/2, there is an excess demand of exports of HH'=80X and Px/Py rises toward Px/Py=1.

6.

The Figure in Problem 5 is consistent with Figure 3-4 in the text. From the left panel of Figure 3-4, we see that Nation 1 supplies no exports of commodity X at Px/Py=1/4 (point A). This corresponds with the vertical or price intercept of Nation 1's supply curve of exports of commodity X (point A).

The left panel of Figure 3-4 also shows that at Px/Py=1, Nation 1 is willing to export 60X (point E). The same is shown by Nation 1's supply curve of exports of commodity X. The other points on Nation 1's supply curve of exports in the figure of Problem 5 can also be derived from the left panel of Figure 3-4, but this is shown in Chapter 4 with offer curves.

Nation 2's demand curve for Nation 1's exports of commodity X could be derived from the right panel of Figure 3-4, as shown in Chapter 4. What is important is that we can use the D and S figure in Problem 5 to explain why the equilibrium relative commodity price with trade is Px/Py=1 and why the equilibrium quantity traded of commodity X is 60 units in Figure 3-4.

7.

See Figure 6 on page 3-8.

The small nation will move from A to B in production, exports X in exchange for Y so as to reach point E > A.

8.

a) The small nation specializes in the production of commodity X only until its opportunity cost and relative price of X equals PW. This usually occurs before the small nation has become completely specialized in production. b) Under constant costs, specialization is always complete for the small nation.

9.

a) See Figure 7. b) See Figure 8.

10.

If the two community indifference curves had also been identical in Problem 9 the relative commodity prices would also have been the same in both nations in the absence of trade and no mutually beneficial trade would be possible.

11.

If production frontiers are identical and the community indifference curves different in the two nations, but we have constant opportunity costs, there would be no mutually beneficial trade possible between the two nations

It is true that Mexico's wages are much lower than U.S. wages (about one fifth), but labor productivity is much higher in the United States and so labor costs are not necessarily higher than in Mexico. In any event, trade can still be based on comparative advantage.

App. 1. See Figure 12 Commodity X is the L-intensive commodity in Nation 2 (as in Nation 1) because the production contract curve bulges toward the L-axis or is everywhere to the left of the diagonal.

App. 2. Since L and K are released from the production of X in a higher ratio than are absorbed in the production of Y, wages fall in Nation 2. This leads to the substitution of L for K in the production of X and Y, so that the K/L ratio falls in the production of both commodities.

Lecture Guide 1. Some Instructors may wish to cover only Sections 1 and 2 of this chapter and skip offer curves. I would not do that since offer curves are a very useful theoretical tool of analysis that has been utilized for over a century. Some modern authors, in the desire to be innovative, are either dropping this tool of analysis from their text or relegating it to a short appendix. I think this is misguided and wrong.

2. I would cover Sections 1-3 in the first lecture and Sections 4-6 in the second lecture, paying special attention to the shape of offer curves and to the relationship between general and partial equilibrium analyses.

Answer to Problems 1. See Figure 1.

The equilibrium Py/Px=P'2=1/P2.

2. See Figure 2.

3. See Figure 3.

4. See Figure 4.

5. a) A nation's offer curve is similar to a demand curve because it shows the nation's demand for imports. b) A nation's offer curve is similar to a supply curve because it shows the nation's supply for exports. c) An offer curve shows how much of its import commodity a nation demands in order to supply various amounts of its export commodity. The usual demand and supply curves measure the quantity demanded and supplied, respectively.

6. a) See Figure 5. b.) The quantity of imports demanded by Nation 1 at PF' exceeds the quantity of exports of Y supplied by Nation 2. Therefore, Px/Py declines (Py/Px rises) until the quantity demanded of imports of Y by Nation 1 equals the quantity of exports of Y supplied

by Nation 2 at PB=PB'. c.) The backward bending (i.e., negatively sloped) segment of Nation 1's offer curve indicate that nation 1 is willing to give up less of X for larger amounts of Y.

7. a) See Figure 6 on page 34. b) The nation with the offer curve with the greater curvature gains more from trade. c) The nation with the offer curve with the greater curvature gains more from trade because the greater curvature of the offer curve reflects the nation's weaker or less intense demand for the other nation's export commodity.

8. See Figure 7.

From the left panel of Figure 4.4, we see that Nation 2 does not export any amount of commodity Y at Px/Py=4, or Py/Px=1/4. This gives point A on Nation 2's supply curve of the exports of commodity Y (S). From the left panel of Figure 4.4, we also see that at Px/Py=2 or Py/Px=1/2, Nation 2 exports 40Y. This gives point H on S. Other point on S could similarly be derived. Note that S in Figure 7 is identical to S in Figure 4.6 in the text showing Nation 1's exports of commodity X. From the left panel of Figure 4.3, we see that Nation 1 demands 60Y of Nation 2's e exports at Px/Py=Py/Px=1. This gives point E on Nation 1's demand curve of Nation 2's exports of commodity Y (D). From the left panel of Figure 4.3, we can estimate that Nation 1 demands 40Y at Py/Px=3/2 (point H on D in Figure 7) and 120Y at Py/Px=2 (point H' on D).

The equilibrium relative commodity price of commodity Y is Py/Px=1. This is determined at the intersection of D and S in Figure 7. At Py/Px=3/2, there is an excess supply of R'R=30Y and Py/Px falls to Py/Px=1. On the other hand, at Py/Px=1/2, there is an excess demand of HH'=80Y and Py/Px rises to Py/Px=1. Note also that Figure 7 is symmetrical with Figure 4.6 in the text.

9. a) The analysis in the answer to Problem 8 refers to partial equilibrium analysis because it makes use of the traditional demand and supply curves. These refer to the market for commodity Y and abstract from all the interconnections that exist between the market for commodity Y and the market for all the other commodities in the e economy. As such, it provides only an approximation to the answer sought. b) The analysis of Figure 4.5 relies on offer curves. These incorporate demand and supply information in both nations and for both commodities (in our two-nation, two-commodity world). As such, they allow us to trace a change in demand or supply, for either commodity, in either nation, on the demand and supply of the other commodity and in the other nation, as well as the repercussions from the original change on the demand and supply for both commodities in both nations.

Thus, Figure 4-5 refers to general equilibrium analysis. This is admittedly more difficult than partial equilibrium analysis, but it also provides a complete and explicit answer to the problem.

b) The partial equilibrium analysis shown in Figure 7 here and in Figure 4.6 in the text and the general equilibrium analysis provided by Figure 4.5 are related because both are derived from the same basic information (the production frontier and the indifference map of each nation). Partial equilibrium analysis, however, utilizes only part, not all, of the information provided by the production frontier and the indifference maps, as general equilibrium analysis does.

10. See Figure 8 on page 36.

In Figure 8, Nation 2 is the small nation and we magnified the portion of the offer curve of Nation 1 (the large nation) near the origin (where Nation 1's offer curve coincides with PA=1/4, Nation 1's pretrade relative commodity price with trade). This means that Nation 2 can import a sufficiently small quantity of commodity X without perceptibly affecting Px/Py in Nation 1. Thus, Nation 2 is a price taker and captures all of the benefits from its trade with Nation 1. The same would be true even if Nation 2 were not a small nation, as long as Nation 1 faced constant opportunity costs and did not specialize completely in the production of commodity X with trade.

11.

See Figure 9 on page 36. Figure 9 shows that in the unlikely event that both nations faced constant costs, the offer curves of both would be straight lines until both nations became completely specialized in production. Afterwards, offer curves would assume their normal shape and determine the equilibrium Px/Py=PE at their intersection at point E.

12. a) If the terms of trade of a nation improved from 100 to 110 over a given period of time, the terms of trade of the trade partner would deteriorate by about 9 percent over the same period of time. b) A deterioration in the terms of trade of the trade partner can be said to be unfavorable because the trade partner must pay a higher price for its imports in terms of its exports. This does not necessarily mean that the welfare of the trade partner has decreased because the deterioration in its terms of trade may have resulted from an increase in productivity that is shared with the other nation.

13.

Under the conditions of tight supply that prevailed during the 1970s, OPEC was given credit for the sharp increase in petroleum prices; but when excess supplies arose from the second half of the 1980s to most of the 1990s, OPEC was unable to prevent almost equally sharp price declines. Thus, OPEC does not seem able to set petroleum prices.

Lecture Guide 1. This is one of the most important chapters in the book. It is also a long chapter and requires about four lectures to adequately cover.

2. In the first lecture, I would cover Sections 1-3.

3. In the second lecture, I would cover Section 4. This, of course, is one of the most important sections in the book. I would proceed slowly and carefully here and I would also assign problems 1-8 and grade problems 1-3, 5, 6 to make sure that students clearly understand the meaning of the theory (the answer to problems 4 and 7 appears at the end of the book).

4. In the third lecture, I would cover section 5 on the factor-price equalization theorem and income distribution. This is a difficult section. Case Studies 5-3 and 5-4 add a note of realism to the discussion. I would also assign problems 9 and 10.

Answer to Problems 1.

a) See Figure 1. b) The slope of the lines measuring K/L of each commodity in Nation 2 fall if w/r rises in Nation 2 as a result of international trade. c) The slope of the lines measuring K/L of each commodity in Nation 1 rise if w/r falls in Nation 1 as a result of international trade. d) Given the results in parts (a) and (b), international trade reduces the difference in the K/L in the production of each commodity in the two nations as compared with the pretrade situation.

2.

a) See Figure 2. b) The comparative advantage of each nation is determined by differences in production conditions only since tastes are identical. c) The two nations consume different amounts of the two commodities in the absence of trade but the same amounts with trade because internal prices differ without trade but are identical with trade.

a) Besides a difference in factor endowments, the production frontier of two nations could differ also because of a difference in technology. b) A difference in the production frontier of two nations due to a difference in the technology is prevented by assumption by the H-O model. c) Another possible cause (besides a difference in production frontiers) of a difference in relative commodity prices between two nations in the absence of trade is a difference in tastes.

7.

See Figure 6.

8.

People in developing countries consume very different goods and services than U.S. consumers not because tastes are very different from the tastes of U.S. consumers but because incomes are so different (much lower) than in the United States.

a) If tastes change in favor of commodity Y (the commodity of its comparative disadvantage) in Figure 5-4 for Nation 1, Px/Py will be lower in Nation 1 because point A will move up and to the left. b) The effect of the change in tastes examined in part (a) for Nation 1 will cause r/w to rise in Nation 1. c) The effect of the changes examined in parts (a) and (b) will be to increase the volume of trade. These changes will improve the partner's terms of trade.

The statement was made by Gottfried Haberler in his Survey of International Trade Theory, Special Papers in International Economics, No.1 (Princeton, N.J.: Princeton University Press, International Finance Section, July 1961), p. 18.

While the statement is true, it does not detract from Samuelson's great contribution in rigorously showing the conditions under which trade would bring about the complete equality in the returns to homogeneous factors among nations.

11.

Internatioal trade with developing economies, especially newly industrializing economies (NIEs), contributed in two ways to increased wage inequalities between skilled and unskilled workers in the United States during the past two decades. Directly, by reducing the demand for unskilled workers as a result of increased U.S. imports of labor-intensive manufactures and, indirectly, by speeding up the introduction of laborsaving innovations, which further reduced the U.S. demand for unskilled workers.

International trade, however, was only a small cause of increased wage inequalities in the United States. The most important cause was technological change.

12.

a) Leontief found that U.S. import substitutes were more K-intensive than U.S. exports even though the United States was the most K-rich nation. This implied factorintensity reversal and rejection of the H-O trade model. b) Kravis found that wages in U.S. export industries were higher than in U.S. importcompeting industries, reflecting the greater productivity of labor in U.S. exports than in U.S. import substitutes. This was confirmed by Keesing who found that U.S. exports were more skill intensive than the exports of 9 other industrial nations.

By adding human to physical capital, Kenen succeed in eliminating the paradox.

Baldwin found that including human capital and excluding natural-resource industries eliminated the paradox. c) The paradox was seemingly resolved by Leamer, Stern and Maskus, and Salvatore and Barazesh by comparing the K/L ratio in U.S. production vs. U.S. consumption, rather than in exports vs. imports when natural-resource-based industries are excluded.

d) Factor-intensity reversal seems to be rather rare in the real world.

13.

a) See Figure 7. b) Factor-intensity reversal could occur if the substitutability of K for L in the production of X was much greater than for Y and r/w was lower in Nation 2 than in Nation 1. c) Minhas found factor-intensity reversal to be fairly frequent. However, by correcting an important source of bias in the Minhas study, Leontief showed that factorintensity reversal was much less frequent. Ball tested another aspect of Minhas' conclusion and confirmed Leontief's results that factor-intensity reversal was rare in the real world.

14.

With factor-intensity reversal, a commodity is L-intensive in one nation and K-intensive in the other. The H-O model would then predict that both nations would export the same commodity. Since this is impossible, both nations must export the commodity intensive in the same factor.

If this is the K-intensive commodity, the demand for K will increase in both nations. If it is the L-intensive commodity, the demand for K will fall in both nations. Thus, the price of K will either rise or fall in both nations, and international differences in the price of K will decrease, increase or remain unchanged depending on the rate of change in the price of K in the two nations.

15.

a) By allowing for different technologies and factor prices across countries, nontraded goods, transportation costs, and by using better and more disaggregated data. b) Factor endowments broadly defined seem to explain comparative advantage well. c) We retain a qualified factor-endowments H-O model of international trade.

App. 2. See Figure 8.

App. 4. The effect of the opening of trade on the real income of labor and capital in Nation 2 (the K-abundant nation) if L is mobile between the two industries in Nation 2 but K is not is to increase Py/Px and to cause more L to be used in the production of Y. Wages then fall in terms of Y but rise in terms of X. On the other hand, the return on capital increases in the production of Y but falls in the production of X.

Lecture Guide: 1.

Although this is not a core chapter, Sections 6.1, 6.3 and 6.4 are important ones because they present some of the most recent developments in international trade theory.

2.

I would cover sections 1, 2, and 3 in lecture 1. The material is not difficult but very important. I would also assign problems 1-3.

3.

I would cover section 4 in lecture 2. This is the most important section in the chapter. I would pay very close attention to Figures 6-2 and 6-3. These require reviewing from principles of economics, the meaning of differentiated products, monopolistic competition, economies of scale, and the determination of profit maximization by the firm. I would also assign problems 4-9 problems 4-9 and go over in class problems 6-9.

In lecture 3, I would cover sections 5 and 6 and assign problems 10-14.

6.

See Figure 4.

The AC and the MC curves in Figure 4 are the same as in Figure 6-2. However, D and the corresponding MR curve are higher on the assumption that other firms have not yet imitated this firm's product, reduced its market share, or competed this firm's profits away. In Figure 4, MR=MC at point E, so that the best level of output of the firm is 5 units and price is $4.50. Since at Q=5, AC=$3.00, the firm earns a profit of AB=$2.00 per unit and $10.00 in total.

7.

a) Monopolistic competition resembles monopoly because under both forms of market organization the firm produces a product that is unique (i.e., no other firm produces an identical product). b) Monopolistic competition is different from monopoly because under monopolistic competition there are many other firms that produce a similar product. On the other hand, there is no close substitute for the product sold by a monopolist.

Furthermore, under monopolistic competition, entry into the industry is easy. As a result, attracted by this firm's profits, more firms enter the industry to produce similar products. This reduces the monopolistically competitive firm's market share (i.e., its demand and corresponding MR curves shift down) until we get to the situation depicted by Figure 6-2 in the text, where P=AC and our firm breaks even. On the other hand, under monopoly, entry into the industry is blocked, so that the monopolist can continue to earn profits in the long run.

c) The difference between monopoly and monopolistic competition is important for consumer welfare because consumers get a greater variety of the commodity at a lower price with monopolistic competition than with monopoly.

8.

A perfectly competitive firm faces an infinitely elastic or horizontal demand curve. This means that the firm is a price taker and can sell any quantity of the homogenous product at the price determined at the intersection of the market demand and supply curves for the commodity.

Both the demand curves faced by the monopolistic competitive firm and the monopolist are downward sloping, indicating that each can sell more units of the commodity by lowering its price. However, the demand curve facing the monopolistically competitive firm generally has a smaller inclination (i.e., it is more elastic) than the demand curve facing the monopolist because the former sells a commodity for which many good substitute are available.

9.

If the C curve had shifted down only half as much as curve C' in Figure 6-3, the new equilibrium point would be at P=AC=$2.50 and N=350.

10.

See Figure 5 on the previous page.

11.

The increased pirating or production and sale of counterfeit American goods without paying royalties by foreign producers shorten the U.S. product cycle or the time during which the U.S. firm can reap the benefits from the new product or technology it introduced and thus reduces the ability of U.S. firms to engage in research and development (R & D) new product cycles.

12.

See Figure 6 on the previous page.

With transportation costs specialization would proceed to point C in Nation 1 and point C’ in Nation 2. Pc in nation 1 (the nation exporting commodity X) is smaller than Pc' in Nation 2 (the country importing commodity X) by the relative cost of transporting each unit of commodity X from Nation 1 to Nation 2. Trade does not seem to be in equilibrium because transportation costs are expressed in terms of commodity X.

13.

See Figure 7 on the next page.

P2 exceeds P1 by the relative cost of transporting one unit of commodity X from Nation 1 to Nation 2.

The United States has become the most competitive economy in the world since the early 1990’s, while the data in Table 7.2 refers to the 1965-1990 period.

App. 1a. See Figure 16.

1b. For production and consumption to actually occur at the new equilibrium point after the doubling of K in Nation 2, we must assume either than commodity X is inferior or that Nation 2 is too small to affect the relative commodity prices at which it trades.

1c. Px/Py must rise (i.e., Py/Px must fall) as a result of growth only.

Px/Py will fall even more with trade.

2. If the supply of capital increases in Nation 1 in the production of commodity Y only, the VMPLy curve shifts up, and w rises in both industries. Some labor shifts to the production of Y, the output of Y rises and the output of X falls, r falls, and Px/Py is likely to rise.

3. Capital investments tend to increase real wages because they raise the K/L ratio and the productivity of labor. Technical progress tends to increase K/L and real wages if it is L-saving and to reduce K/L and real wages if it is K-saving.

In the United States: the opportunity cost of one unit of beef is 2 chips; the opportunity cost of one chip is 1/2 unit of beef.

In Germany: the opportunity cost of one unit of beef is 4 chips; the opportunity cost of one chip is 1/4 unit of beef.

b.

The United States has a comparative cost advantage in beef with respect to Germany, while Germany has a comparative cost advantage in computer chips.

c.

The range for mutually beneficial trade between the United States and Germany for each unit of beef that the United States exports is 2C < 1B < 4C

d.

(ch07)

Both the United States and Germany would gain 1 chip for each unit of beef traded.

2. Given: (1) two nations (1 and 2) which have the same technology but different factor endowments and tastes, (2) two commodities (X and Y) produced under increasing costs conditions, and (3) no transportation costs, tariffs, or other obstructions to trade. Prove geometrically that mutually advantageous trade between the two nations is possible.

Note: Your answer should show the autarky (no-trade) and free-trade points of production and consumption for each nation, the gains from trade of each nation, and express the equilibrium condition that should prevail when trade stops expanding.)

Ans.: See Figure 1.

Nations 1 and 2 have different production possibilities curves and different community indifference maps. With these, they will usually end up with different relative commodity prices in autarky, thus making mutually beneficial trade possible.

In the figure, Nation 1 produces and consumes at point A and Px/Py=PA in autarky, while Nation 2 produces and consumes at point A' and Px/Py=PA'. Since PA < PA', Nation 1 has a comparative advantage in X and Nation 2 in Y. Specialization in production proceeds until point B in Nation 1 and point B' in Nation 2, at which PB=PB' and the quantity supplied for export of each commodity exactly equals the quantity demanded for import. Thus, Nation 1 starts at point A in production and consumption in autarky, moves to point B in production, and by exchanging BC of X for CE of Y reaches point E in consumption. E > A since it involves more of both X and Y and lies on a higher community indifference curve. Nation 2 starts at A' in production and consumption in autarky, moves to point B' in production, and by exchanging B'C' of Y for C'E' of X reaches point E'in consumption (which exceeds A').

At Px/Py=PB=PB', Nation 1 wants to export BC of X for CE of Y, while Nation 2 wants to export B'C' (=CE) of Y for C'E' (=BC) of X. Thus, PB=PB' is the equilibrium relative commodity price because it clears both (the X and Y) markets.

3.

Draw a figure showing: (1) in Panel A a nation's demand and supply curve for A traded commodity and the nation's excess supply of the commodity, (2) in Panel C the trade partner's demand and supply curve for the same traded commodity and its excess demand for the commodity, and (3) in Panel B the supply and demand for the quantity traded of the commodity, its equilibrium price, and why a price above or below the equilibrium price will not persist. At any other price, QD  QS, and P will change to P2.

Ans. See Figure 2.

The equilibrium relative commodity price for commodity X (the traded commodity exported by Nation 1 and imported by Nation 2) is P2 and the equilibrium quantity of commodity X traded is Q2.

a) Identify the conditions that may give rise to trade between two nations. b) What are some of the assumptions on which the Heckscher-Ohlin theory is based? c) What does this theory say about the pattern of trade and effect of trade on factor prices?

Answer: a)

Trade can be based on a difference in factor endowments, technology, or tastes between two nations. A difference either in factor endowments or technology results in a different production possibilities frontier for each nation, which, unless neutralized by a difference in tastes, leads to a difference in relative commodity price and mutually beneficial trade. If two nations face increasing costs and have identical production possibilities frontiers but different tastes, there will also be a difference in relative commodity prices and the basis for mutually beneficial trade between the two nations. The difference in relative commodity prices is then translated into a difference in absolute commodity prices between the two nations, which is the immediate cause of trade.

b)

The Heckscher-Ohlin theory (sometimes referred to as the modern theory – as opposed to the classical theory - of international trade) assumes that nations have the same tastes, use the same technology, face constant returns to scale (i.e., a given percentage increase in all inputs increases output by the same percentage) but differ widely in factor endowments. It also says that in the face of identical tastes or demand conditions, this difference in factor endowments will result in a difference in relative factor prices between nations, which in turn leads to a difference in relative commodity prices and trade. Thus, in the Heckscher-Ohlin theory, the international difference in supply conditions alone determines the pattern of trade. To be noted is that the two nations need not be identical in other respects in order for international trade to be based primarily on the difference in their factor endowments.

c)

The Heckscher-Ohlin theorem postulates that each nation will export the commodity intensive in its relatively abundant and cheap factor and import the commodity intensive in its relatively scarce and expensive factor. As an important corollary, it adds that under highly restrictive assumptions, trade will completely eliminate the pretrade relative and absolute differences in the price of homogeneous factors among nations. Under less restrictive and more usual conditions, however, trade will reduce, but not eliminate, the pretrade differences in relative and absolute factor prices among nations. In any event, the Heckscher-Ohlin theory does say something very useful on how trade affects factor prices and the distribution of income in each nation. Classical economists were practically silent on this point.

5. consumers demand more of commodity X (the L-intensive commodity) and less of commodity Y (the K- intensive commodity). Suppose that Nation 1 is India, commodity X is textiles, and commodity Y is food. Starting from the no-trade equilibrium position and using the Heckscher-Ohlin model, trace the effect of this change in tastes on India's (a) relative commodity prices and demand for food and textiles, (b) production of both commodities and factor prices, and (c) comparative advantage and volume of trade. (d) Do you expect international trade to lead to the complete equalization of relative commodity and factor prices between India and the United States? Why? Answer: a.

The change in tastes can be visualized by a shift toward the textile axis in India's indifference map in such a way that an indifference curve is tangent to the steeper segment of India's production frontier (because of increasing opportunity costs) after the increase in demand for textiles. This will cause the pretrade relative commodity price of textiles to rise in India.

b.

The increase in the relative price of textiles will lead domestic producers in India to shift labor and capital from the production of food to the production of textiles. Since textiles are L-intensive in relation to food, the demand for labor and therefore the wage rate will rise in India. At the same time, as the demand for food falls, the demand for and thus the price of capital will fall. With labor becoming relative more expensive, producers in India will substitute capital for labor in the production of both textiles and food.

Even with the rise in relative wages and in the relative price of textiles, India still remains the L-abundant and low-wage nation with respect to a nation such as the United States. However, the pretrade difference in the relative price of textiles between India and the United States is now somewhat smaller than before the change in tastes in India. As a result the volume of trade required to equalize relative commodity prices and hence factor prices is smaller than before. That is, India need now export a smaller quantity of textiles and import less food than before for the relative price of textiles in India and the United States to be equalized.

Similarly, the gap between real wages and between India and the United States is now smaller and can be more quickly and easily closed (i.e., with a smaller volume of trade).

c.

(ch07)

Since many of the assumptions required for the complete equalization of relative commodity and factor prices do not hold in the real world, great differences can be expected and do in fact remain between real wages in India and the United States. Nevertheless, trade would tend to reduce these

differences, and the H-O model does identify the forces that must be considered to analyze the effect of trade on the differences in the relative and absolute commodity and factor prices between India and the United States.

4.

(a) Explain why the Heckscher-Ohlin trade model needs to be extended. (b) Indicate in what important ways the Heckscher-Ohlin trade model can be extended. (c) Explain what is meant by differentiated products and intra-industry trade.

Anwer: a.

The Heckscher-Ohlin trade model needs to be extended because, while generally correct, it fails to explain a significant portion of international trade, particularly the trade in manufactured products among industrial nations.

b.

The international trade left unexplained by the basic Heckscher-Ohlin trade model can be explained by (1) economies of scale, (2) intra-industry trade, and (3) trade based on imitation gaps and product differentiation.

c.

Differentiated products refer to similar, but not identical, products (such as cars, typewriters, cigarettes, soaps, and so on) produced by the same industry or broad product group. Intra-industry trade refers to the international trade in differentiated products.

Lecture Guide 1.

I would cover sections 1 and 2 and assign problems 1-2 in the first lecture. The most difficult part of section 2 is the meaning and measurement of consumer and producer surplus. Since a clear understanding of the meaning and measurement of consumer and producer surplus is crucial in evaluating the effect of tariffs, I would explain these concepts very carefully.

2.

I would then cover section 3 and assign problems 3-6 in the second lecture. The theory of tariff structure is also very difficult and important, and so I would also explain this concept very carefully. I found that the best way to explain it is by using the simple example used in the text of the suit with and without imported inputs.

3.

The rest of the chapter can be skipped without loss of continuity by those Instructors who do not wish to cover the general equilibrium effects of tariffs.

4.

For those Instructors who wish to cover the rest of the chapter, I would take up another two lectures to do so. I would also assign and grade problems 8-14 to make sure that students understand the material.

5.

In covering section 8.4, I would pay special attention to the explanation of Figure 8-5 and to the Stolper-Samuelson theorem.

6.

In covering Section 8.6, please note that the optimum tariff can only be discussed intuitively without trade indifference curves (examined in Appendix A8.6).

Answer to Problems 1.

a) Consumption is 70Y, production is 10Y and imports are 60Y (see Figure 1 on the next page). b) Consumption is 60Y, production is 20Y and imports are 40Y (see Figure 1). c) The consumption effect is -10Y, the production effect is +10Y, the trade effect is -20Y and the revenue effect is $40 (see Figure 1).

2.

a) The consumer surplus is $245 without and $l80 with the tariff (see Figure 1). b) Of the increase in the revenue of producers with the tariff (as compared with their revenues under free trade), $l5 represents the increase in production costs and another $15 represents the increase in rent or producer surplus (see Figure 1). c) The dollar value or the protection cost of the tariff is $l0 (see Figure 1).

3.

This will increase the rate of effective protection in the nation.

6.

a) g=70% b) See the first paragraph of section 8.3b.

7.

See Figure 2.

8.

When Nation 1 (assumed to be a small nation) imposes an import tariff on commodity Y, the real income of labor falls and that of capital rises.

9.

Py/Px rises for domestic producers and consumers. As production of Y (the Kintensive commodity) rises and that of X falls, the demand and income of K rises and that of L falls. Therefore, r rises and w falls.

10.

If Nation 1 were instead a large nation, then Nation 1's terms of trade rise and the real income of L may also rise.

India is more likely to restrict imports of K-intensive commodities in which India has a comparative disadvantage and this is likely to increase the return to capital and reduce the return to labor according to the Stolper-Samuelson theorem.

12.

See Figure 3 on the previous page.

13.

See Figure 4.

14.

The volume of trade may shrink to zero (the origin of offer curves).

App. 1. The more elastic SH and SF are, the lower is the free trade price of the commodity and the lower is the increase in the domestic price of the commodity as a result of the tariff.

App. 2a. The supply curve of the nation for the commodity shifts up and to the left (as with the imposition of any tax); this does not affect the consumption of the commodity with free trade, but it reduces domestic production and increases imports of the commodity; it also increases the revenue effect and reduces producers' surplus. b. The imposition of a tariff on imported inputs going into the domestic production of the commodity will have no effect on the size of the protection cost or deadweight loss.

App. 3. See Figure 5 (on the next page).

App. 4. See Figure 6.

App. 5. Real w will fall in terms of Y and rise in terms of X. On the other hand, real r will rise in terms of Y and fall in terms of X. This can be seen by drawing a figure similar to Figure 8-10, but with the VMPLy curve shifting upward.

App. 6a. See Figure 7. b. After Nation 1 has imposed an optimum tariff and Nation 2 has retaliated with an optimum tariff of its own, the approximate terms of trade for Nation 1 is 0.8, while the approximate terms of trade of Nation 2 is 1.25. c.

(ch08)

Nation 1's welfare declines from the reduction in the volume and in the terms of trade. Although nation 2's terms of trade are higher than under free trade, the volume of trade has shrunk so much that nation 2's welfare is also likely to be lower than under free trade.

Lecture Guide: 1.

This is an important core chapter examining some of the most recent developments in international trade policy.

2.

I would cover sections 1 and 2 in lecture 1. I would pay particular attention to Figure 9-1, which examines the partial equilibrium effects of an import quota.

3.

I would cover section 3 in lecture 2. Here I would clearly explain the difference between a regular import quota and a voluntary export restraint. I would also clearly explain dumping and Figure 9-2 (which deals with export subsidies). The five case studies serve to highlight the theory and show the relevance of the theory in today's world.

4.

I would cover section 4 in lecture 3. Here I would give special attention to the fallacious arguments for protection since they are often heard in common discussions of trade matters. I would also clearly explain the importance of strategic trade and industrial policy and the political economy of who gets protected.

5.

I would cover section 5 in lecture 4, which examines strategic trade and industrial policies policies with game theory. This is not difficult and the students will find it very interesting.

6.

Sections 6 and 7 can be covered in lecture 5. Here I would stress the Uruguay Round and the outstanding international trade problems.

Answer to Problems: 1.

Nations restrict trade either in response to lobbying by the producers of a commodity in which the nation has a comparative disadvantage or to gain a strategic advantage in relation to other nations. The first leads to a welfare loss for he nation as a whole. The second is very difficult to achieve.

2.

The partial equilibrium effects of the import quota are: Px=$1.50; consumption is 45X, of which 15X are produced domestically; by auctioning off import licenses, the revenue effect would be $15.

3.

The partial equilibrium effects of the import quota are: Px=$2.50; consumption is 40X, of which 10X are produced domestically; the revenue effect is $45.

4.

The partial equilibrium effects of the quota are: Px=$2; domestic production and consumption are 50X; The revenue is zero.

(ch09)

9-3

Dominick Salvatore

International Economics – 11h Edition

Instructor’s Manual

5.

The partial equilibrium effects of the quota are: Px=$1; consumption is 70X, production is 30X, and revenue is zero.

6.

The partial equilibrium effects of a negotiated export quota of 30X are: Px=$4; domestic production is 40X, of which 10X are consumed at home.

7.

An export tariff or quota, as an import tariff or quota, affects the price of the commodity and domestic consumption and production. But the effects are the opposite.

8.

See Figure 1.

The equilibrium price of the commodity is Px=OC and the equilibrium quantity is Qx=OB in Figure 1.

9.

If the supply curve of the commodity in Figure 1 referred to a cartel of exporters acting as a monopolist, Px=OF and Qx=OA (see Figure 1).

10.

Px is higher and Qx smaller when exporters behave as a monopolist.

11.

a) The monopolist should charge P1=$4 in the domestic market and P2=$3 in Figure 9-5 in Appendix A9.2.

b) This represents the best, or optimal distribution of sales between the two markets because any other distribution of sales in the two markets gives less revenue.

12.

See Figure 2. To the left of point A, the domestic firm faces higher longrun average costs of production (LACD) than the foreign firm (LACF). To the right of point A the opposite is the case.

13.

a) If the entries in the top left-hand corner of Table 9-5 were changed to +10, +10, then both Boeing and Airbus would produce the aircraft without any subsidy, and so no strategic trade and industrial policy would be needed in the U.S. or Europe. b) If the entries in the top left-hand corner of Table 9-5 were changed to +5, +0, then both Boeing and Airbus would produce the aircraft without any subsidy, and so no strategic trade and industrial policy would be needed in the U.S. or Europe. *Note that even though Airbus only breaks even, in economics we include a normal return on investment as part of costs. Thus, Airbus would remain in business because it would earn a normal return on investment. c) If the entries in the top left-hand corner of Table 9-5 were changed to +5, -10, then both Boeing produces and Airbus does not produce without any subsidy.

With a subsidy of at least $10 million per year, however, Airbus would enter the market and lead to a loss of $100 million for Boeing unless the U.S. government would provide a subsidy of at least $5 million per year to Boeing.

14.

The answer to part (a) and (b) are presented in Appendix A9.3.

App. 1. See Figure 3 on page 90.

App. 2. In order to maximize to maximize total profits the domestic monopolist practicing international price discrimination should sell at the price of Pd=$20 in the domestic market and at the price of Pf=$15 in the foreign market.

App. 3. By imposing a 100% tax on the production of commodity X and giving it as a subsidy to producers of commodity Y.

This is not a core chapter and I would skip it except for section 6. Section 6 is an important section and can be regarded as an extension of Chapter 9, which is a core chapter. Section 6 deals with a very important set of current events.

2.

Section 6 is a long section and may require two classes to be adequately presented.

I would cover subsections a-d in one class and subsection e as well as both case studies in the second class. Case Studies 10-1 to 10-6 can be used for a very\ stimulating class discussion.

3.

While section 6 can be presented without covering the material in sections 1-5, some terms discussed in sections 1-5 (such as trade creation and trade diversion) need to be defined.

4.

In a one-year course in international economics, I would cover the entire chapter.

I would then cover sections 10-1 to 10-3 in one class and sections 10-4 and 10-5 In the second class. In the first class, the most important aspect would be the presentation and clear explanation of Figures 10-1 and 10-2.

Answers to Problems: 1.

If Nation A imposes a 100 percent ad valorem tariff on imports of commodity X from Nation B and Nation C, Nation A will produce commodity X domestically because the domestic price of commodity X is $10 as compared with the tariffinclusive price of $16 if Nation A imported commodity X from Nation B and $12 if Nation A imported commodity X from nation C.

2. a)

If Nation A forms a customs union with Nation B, Nation A will import commodity X from Nation B at the price of $8 instead of producing it itself at $10 or importing it from Nation C at the tariff-inclusive price of $12.

b)

When Nation A forms a customs union with Nation B this would be a tradecreating customs union because it replaces domestic production of commodity X at Px=$10 with tariff-free imports of commodity X from Nation B at Px=$8.

3.

If Nation A imposes a 50 percent ad valorem tariff on imports of commodity X from Nation B and Nation C, Nation A will import commodity X from nation C at the tariff-inclusive price of $9 instead of producing commodity X itself or importing it from Nation B at the tariff-inclusive price of $12.

4. a)

If Nation A forms a customs union with Nation B, Nation A will import commodity X from Nation B at the price of $8 instead of importing it from Nation C at the tariff-inclusive price of $9.

b) When Nation A forms a customs union with Nation B this would be a trade-diverting customs union because it replaces lower-price imports of commodity X of $6 (from the point of view of Nation A as a whole) with higher priced imports of commodity X from Nation B at $8.

Specifically, Nation A's importers do not import commodity X from Nation C because the tariff-inclusive price of commodity X from Nation C is $9 as compared with the no-tariff price of $8 for imports of commodity X from Nation B. However, since the government of Nation A collects the $3 tariff per unit on imports of commodity X from Nation C, the net effective price for imports of commodity X from Nation C is really $6 for Nation A as a whole.

See Figure 10-1 in the text. Any figure similar to Figure 10-1 in the text would do.

6.

The welfare gains that Nation 2 receives from joining Nation 1 to form a customs Union is given by the sum of the areas of triangles CJM and BHN in Figure 10-1 in the text. Any similar figure and sum of corresponding triangles would, of course, be adequate.

7.

See Figure 10-2 in the text. Any figure similar to Figure 10-2 in the text would do.

8.

The welfare loss that Nation 2 receives from joining Nation 1 to form a customs union is given by C'JJ'+B'HH'- MNH'J'=$11.25 in Figure 10-2 in the text.

Any similar figure and sum of corresponding triangles minus the area of corresponding rectangle would, of course, be adequate.

9.

See Figure 1 and compare it to Figure 10-2.

10.

The net gain from the trade-diverting customs union shown in Figure 1 is given by C'JJ'+B'HH'-MJ'H'N. As contrasted with the case in Figure 10-2, however, the sum of the areas of the two triangles (measuring gains) is greater than the area the rectangle (measuring the loss). Thus, the nation would now gain from the formation of a custom union. Had we drawn the figure on graph paper, we would have been able to measure the net gain in monetary terms also.

11.

A trade-diverting customs union is more likely to lead to a welfare gain of a member nation (1) the smaller is the relative inefficiency of nation 3 with respect to nation 1, (2) the higher is the level of the tariff, and (3) the more elastic are Dx and Sx in nation 2. These can seen by comparing Figure 10-2 in the text with Figure 1 on the next page.

12.

See Figure 2. The formation of the customs union has no effect.

13.

NAFTA created much more controversy because the very low wages in Mexico led to great fears of large job losses in the U. S.

14.

The possible cost to the U.S. from EU92 arose from the increased efficiency and competitiveness of the E.U. The benefit arose because a more rapid growth in the EU spills into a greater demand for American products, which benefits the U. S. App. Compare points B' and H' in Figure 10-3 with the corresponding points in Figure 3.

Lecture Guide: 1.

This is not a core chapter and I would skip it, except for section 6.

2.

If I covered this chapter, I would present two sections in each of three lectures.

Answer to Problems: 1.

International trade could retard development by: • keeping the nation in primary production; • leading the nation to adopt excessive capital-intensive production techniques; • increasing the propensity to consume, thus reducing the nation's savings rate; • leading to foreign exploitation of natural resources;

2.

Each of the criticisms that international trade can retard development given in the answer to problem 1 can by countered as follows: • As the availability of capital and technology increases, the nation can begin to export manufactured goods; • through appropriate taxes and subsidies the nation can avoid the use of excessive capital-intensive production techniques; • increased taxation can increase the rate of public savings; • taxation and regulation can reduce or eliminate foreign exploitation;

3.

An improvement in the technology of primary production results in a shift in the nation's transformation curve from Y1X1 to Y1X2 in Figure 1.

4.

An improvement in the technology of primary production is likely to lead to deterioration in the terms of trade as the developing nation exports more primary commodities.

5.

A vent for surplus can be shown by a movement from point A inside the nation's production frontier without trade to point A' on the higher production frontier with growth and trade in Figure 2 on the previous page.

a) The nation's commodity terms of trade would be 91.7. b) The nation's income terms of trade would be 119.2. c) The nation's single factoral terms of trade would be 128.4.

7.

The nation of problem 6 will be better off in 2010 as compared with 1980 because its income and single factoral terms of trade rose.

8.

Figure 7-6 in the text shows how deteriorating terms of trade resulting from growth can make a nation worse off after trade than before. This was called immiserizing growth in Chapter 7.

9.

Figure 3 on the previous page shows that when the supply of a commodity increases, its equilibrium price will fall by a greater amount, the more price inelastic is the demand curve for the commodity.

10.

Figure 4 on the next page shows that with a negatively inclined demand curve and a positively inclined supply curve, producers' earnings fluctuate more with a shift in demand (Panel a) than with a shift in supply (Panel b).

11.

Figure 5 shows how a buffer stock could either lead to an unmanageable stock of the commodity or to the running out of the commodity. Specifically, if the buffer stock authority sets price above the long-run equilibrium price of the commodity, it will face an unmanageable stock of the commodity. On the other hand, if the buffer stock authority sets price below the long-run equilibrium level, then the buffer stock authority will run out of the commodity.

12.

A New International Economic Order (NIEO) has not been established because industrial countries did not want to give up control over the present system and pay the economic costs of reforming it along the lines demanded by developing countries. The establishment of a NIEO is no longer a hotly debated topic because developed countries faced serious problems of their own during the 1980s and early 1990s in the form of slow growth and high unemployment. The NIEO was replaced by concerns about globalization in the 1990s.

13.

The Uruguay Round benefited developing countries by the reduction in trade protectionism on agricultural products and labor-intensive commodities. Although protectionism will be reduced, it will still remain relatively high in these products.

14.

Immiserizing growth does not seem to have occurred in most globalizing developing countries despite some deterioration in their terms of trade because the volume of trade and their income terms of trade have increased substantially over the past three decades.

15.

Rich nations should forgive all of the foreign debt of the poorest developing countries because it is impossible for them to repay it or even service it. This, however, might encourage the poorest nations to continue to borrow and even use borrowed funds unwisely knowing that eventually their foreign debt might be forgiven.

See Figure 1.

In Figure 1, the outflow of capital is shown by the leftward and upward shift of the SK curve to S'K. This increases the return on capital until it is equal to that in the host or receiving country.

2.

See Figure 2.

In Figure 2, the outflow of capital is shown by the rightward and downward shift of the SK curve to S'K. This reduces the return on capital until it is equal to that in the investing country.

7.

The Statement is true.

The profitability of a portfolio is equal to the weighted average of the yield of the securities included in the portfolio. Therefore, the profitability of a portfolio of many securities can never exceed the yield of the highest-yield security in the portfolio.

The second part of the statement is also true if the portfolio includes securities for which yields are inversely correlated over time.

8.

See Figure 3. The gain of the investing country is EGR.

9.

See Figure 4. The gain of the host or receiving country is ERM.

10.

The general principle that can be deduced from the answers to the previous two problems and from Figure 12-1 is that the nation with the more rapidly declining VMPK curve gains more. With the VMPK curves declining at equal rates, both nations gain equal amounts.

The rate of return on U.S. direct investment in developing nations often exceeds the rate of return on investment on it investments in developed nations because of relative scarcity of capital and technology and lower wage rates in developing than in developed nations.

11.

U.S. labor generally opposes U.S. investments abroad because they reduce the K/L ratio and the productivity and wages of labor in the United States.

An inflow of foreign capital leads to an increase in the K/L ratio and in the productivity and wages of labor or employment in developing nations.

the consumption, production effect, and the trade effect of the tariff.

(b)

the reduction in consumer surplus, the increase in producer surplus or rent, the tariff revenue, and the protection cost or deadweight loss to the economy as a result of the tariff.

Answ. (a) The consumption effect is equal to BR=-20c; the production effect is equal to GN=20C; therefore, the trade effect is equal to -(BR+GN)=-40c. (b)

2.

The reduction in consumer surplus is FJHB=$90; the increase in producer surplus is FJMG=$30; the revenue effect is NMHR=$40; the protection cost or deadweight loss to the economy is equal to the sum of the area of triangles GMN and BHR or $20.

(a) Explain why and under what conditions the infant-industry argument for an import tariff is valid. (b) How must this argument be qualified?

Answ. (a) The infant-industry argument for tariffs is generally valid, especially for less developed countries (LDCs). It holds that an LDC may have a potential comparative advantage in a particular commodity, say textiles, but that because its initial production costs are too high (due to lack of know-how and the initial small level of output), this industry cannot be established or grow in the LDC in the face of foreign competition. An import tariff is then justified to help the LDC establish the industry and protect it during its "infancy," until the industry has grown in size and efficiency and is able to meet foreign competition. At that time, the tariff is to be removed. (b) In order for the infant-industry argument to be valid, not only must the tariff eventually be removed and the "grown up" industry be able to compete with foreign firms without protection, but the extra return in the industry (after the removal of the protection) must be high enough to justify the costs involved during the period of protection. These costs arise because the commodity is produced domestically rather than imported for less. It may also be difficult a priori to determine which industry or potential industry qualifies for this treatment, and to eventually remove the tariff once it is imposed. Economists also agree that what a tariff can do here, a direct subsidy to the infant industry can do better. This is because a subsidy can be varied so as to provide the infant industry with the same degree of protection as an equivalent import tariff but without distorting relative prices and domestic consumption. However, a subsidy requires revenue, rather than generating it as the tariff does.

How can strategic trade policy justify trade protection?

What difficulties arise in carrying out a strategic trade policy?

Answ. (a) According to strategic trade policy, a nation can create a comparative advantage through temporary trade protection in such fields as semiconductors, computers, telecommunications, and other industries that are deemed crucial to future growth in the nation. These high-technology industries are subject to high risks, require large scale production to achieve economies of scale and give rise to extensive external economies when successful. Strategic trade policy suggests that by encouraging such industries, the nation can enhance its future growth prospects. This is similar to the infant-industry argument in developing nations, except that it is advanced for industrial nations to acquire a comparative advantage in crucial high-technology industries. Most nations do some of this.

Indeed, some economists would go so far as to say that a great deal of the postwar industrial and technological success of Japan is due to its strategic industrial and trade policies. (b) There are three serious difficulties in carrying out strategic trade policy. First, it is extremely difficult to pick winners (i.e., choose the industries that will provide large external economies in the future) and devise appropriate policies to successfully nurture them. Second, since most leading nations undertake strategic trade policies at the same time, their efforts are largely neutralized so that the potential benefits to each may be small. Third, when a country does achieve substantial success with strategic trade policy, this comes at the expense of other countries (i.e., it is a beggar-thy-neighbor policy) and so other countries are likely to retaliate. Faced with all these practical difficulties, even supporters of strategic trade policy grudgingly acknowledge that free trade is still the best policy, after all.

What direct or indirect evidence can you give to conclude that U.S. support for economic integration in Europe did in fact result in the hope-for outcome?

(c)

What are the major economic disputes between the United States and Europe about these days? What dangers do they create?

Answ. (a) The United States supported economic integration in Europe to foster and Strengthen democratic systems in Europe after World War II, resist communism, and to promote peaceful coexistence among European countries, especially Germany and France, which were once bitter enemies.

(b)

Evidence that U.S. support for economic integration in Europe achieved its goals is provided by the fact that the members of the European Union have strong democratic governments and economies, communist regimes have collapsed in Eastern Europe and the Soviet Union, and Germany and France are so closely integrated economically that a future armed conflict between them is practically nil.

(c)

The major economic disputes between the United States and Europe (the European Union) today are about trade protection in agriculture and some services as well as subsidies that the European Union provides to some of its industries, such as Airbus Industrie. These disputes could degenerate into trade wars that would harm both the European Union and the United States.

(a)

Why did large developing nations generally follow a policy of import substitution as a strategy for growth during the 1950s, 1960s, and 1970s?

Why was this not generally possible for small developing nations?

(b)

Why was the policy of import substitution generally a failure?

(c)

Why did developing nations that switched from a policy of import substitution to a policy of export promotion generally grow faster during the past decade?

Answ. (a)

Large developing nations generally followed a policy of import substitution during the 1950s, 1960s, and 1960s because their large domestic market allowed them to reap many of the benefits economies of scale in production even without international trade. On the other hand, small developing nations generally did not have the choice of industrializing through import substitution because their small domestic market would have made production costs unacceptably high.

(b)

the policy of import substitution was generally a failure even in large developing nations because once protection was granted to a domestic industry in order to encourage it establishment and growth, it becomes practically impossible to remove the protection. This led to inefficiencies and higher costs in the developing country even for unprotected industries that use the output of protected industries as intermediate products or inputs in their production processes.

(c)

The developing countries that switched from a policy of import substitution to export promotion generally grew faster than those developing countries that did not make that switch because production for export and international competition stimulated efficiency throughout the economy and resulted in domestic prices more closely reflecting the true opportunity costs of commodities and inputs.

One of the most significant international economic developments of the postwar period is the proliferation of multinational corporations (MNCs). These are firms that own, control or manage production facilities in several countries. With regard to MNCs, explain (a) the reason for their existence; (b) some of the alleged problems that they create for the home country; (c) some of the alleged problems that they create for the host country.

Answ. (a) The basic reason for the existence of MNCs is the competitive advantage that they have over other forms of economic organization based on economies of scale in production, financing, research and development (R&D), and in gathering market information, resulting from a global network of production and distribution. Today, MNCs account for about 25% of world output, and the trade between then parent firms and their foreign affiliates accounts for about one-third of world trade in manufactured goods. (b) The most controversial of the alleged harmful effects of MNCs on the home country is the loss of domestic jobs resulting from foreign direct investments.

However, it must be pointed out that the home country may have lost some of these jobs anyway to foreign competitors. A related problem stems from the export of advanced technology. Countering this harmful effect, however, is the tendency of MNCs to concentrate their R&D in the home country. Finally, easy accessibility of MNCs to the international capital market reduces the effectiveness of domestic monetary policy. (c) Host countries have even more serious complaints against MNCs. First is the alleged domination by the MNC of the hosts' economy. The largest MNCs have yearly sales greater than the GNP of all but a handful of nations. It is further alleged that MNCs absorb local savings and local entrepreneurial talent, use excessive K-intensive production techniques that are inappropriate for developing nations and do not train local labor. Most of these complaints are to some extent true especially for host LDCs and have led these nations to regulate foreign direct investments in order to mitigate the harmful effects and increase the possible benefits.

Lecture Guide: 1.

In the first lecture, I would cover sections 1 and 2a. The average student usually finds the meaning of capital inflows and outflows particularly difficult to understand. Therefore, I would pay special care in presenting the material in section 2a. I would also assign problems 1 to 8.

2.

In the second lecture, I would cover section 2b and go over problems 1-8.

I would present sections 3 and 4 in the third lecture, and stress the meaning and measurement of balance of payments deficits and surpluses.

Sections 5 and 6 (which are mostly descriptive and not difficult) could be left for students to do on their own so that the chapter could still be covered in three lectures.

Answers to Problems: 1. a.

The U.S. debits its current account by $500 (for the merchandise imports) and credits its financial account by the same amount (for the increase in foreign assets in the U.S.).

The U.S. credits its financial account by $500 (the drawing down of its bank balances in London, a capital inflow) and debits capital by an equal amount (to balance the financial credit that the U.S. importer received when the U.K. exporter accepted to be paid in three months).

The U.S. is left with a $500 debit in its current account and a net credit balance of $500 in its financial account.

2. a.

The U.S. debits unilateral transfers by $100 and credits capital by the same amount.

b.

The U.S. credits its current account by $100 and debits capital by the same amount.

c.

The debit of $100 in unilateral transfers and the credit of $100 in current account.

3. a.

The same as 2a.

The net result is the same, but the transaction in part a of this problem refers to "tied" aid while transactions a and b in problem 2 do not.

4.

(ch13)

The U.S. debits its financial account by $1,000 (for the purchase of the foreign stock by the U.S. resident) and also credits its financial account (for the drawing down of the U.S. resident bank balances abroad) by the same amount.

7.

The U.S. debits its current account by $40 for the interest paid, debits its financial account by $400 (for the financial outflow for the repayment of the repayment of the principal to the foreign investors by the U.S. borrower), and then credits its financial account by $440 (the increase in foreign holdings of U.S. assets, a credit).

8. a.

The U.S. credits its financial account by $800 and debits its official reserves account by the same amount.

b.

The official settlements balance of the U.S. will improve (i.e., the U.S. deficit will fall or its surplus will rise) by $800.

Lecture Guide: 1.

This is one of the most important and challenging of the core chapters, and to cover it adequately requires five classes.

2.

I would cover the first three sections in the first class, and spend one class on each of the remaining four sections.

3.

Students find hedging and speculation difficult. I would explain them slowly and very carefully. I would also assign and go over the problems in class.

4.

Section 6 on interest arbitrage and the efficiency of foreign exchange markets is also difficult but very important and so I would cover it slowly and very carefully.

Answers to Problems: 1. a.

With supply curve of pounds S£, the equilibrium exchange rate is R=$2/£1 and the equilibrium quantity is Q=£40 million (point E in Figure 1 on the next page) under a flexible exchange rate system. On the other hand with supply curve of pounds S’£, the equilibrium exchange rate would be R=$3/£1 and the equilibrium quantity would be Q=£20 million (point B in Figure 1).

If the United States wanted to maintain the exchange rate fixed at R=3 in Figure 1 with supply curve S£, the U.S. central bank would gain £40 million in reserves per day.

See Figure 2 on the next page.

b. With supply curve of pounds S*£, the equilibrium exchange rate would be R=$1/£1 and Q=£70 million under a flexible exchange rate system (see Figure 2). c. If the United States wanted to maintain a fixed exchange rate of R=1 in Figure 2 with S*£, the U.S. central bank would lose £50 million of reserves per day.

3.

Use $2 to purchase £1 in New York, use the £1 to purchase 410 yens in London, and use the 410 yens to purchase $2.05 in Tokyo, thus earning $0.05 in profit for each pound so transferred.

4. a. The forces at work that will make the cross exchange rates consistent in currency arbitrage in the previous problem are as follows. The selling of pounds for yens in London will reduce the yen price of the pound in London until it is 400 yens to 1. b. The consistent cross rates in Problem 3 are: $2=£1=400 yens.

5. a.

The pound is at a three-month forward premium of 1c or 0.5% (or 2%/year) with respect to the dollar.

b.

The importer would have to purchase forward £10,000 pounds for delivery in three months at today's FR=$1.96/£1.

After three months (and regardless of what the spot rate is at that time), the importer would pay $19,600 and obtain the £10,000 he needs to make the payment.

8.

The exporter would have to sell forward £10,000 pounds for delivery in three months at today's FR=$1.96/£1.

After three months, the exporter will deliver the £10,000 and receive $19,600.

9.

The speculator can speculate in the forward exchange market by purchasing pounds forward for delivery in three months at FR=$2/£1.

If the speculator is correct, he will earn 5c per pound purchased.

10.

The speculator can speculate in the forward exchange market by selling pounds forward.

If the speculator is right, he will earn 5c per pound transferred.

If, on the other hand, SR=$2.05/£1, the speculator will lose 5c per pound.

11.

The interest arbitrageur will earn 2% per year from the purchase of foreign threemonth treasury bills if he covers the foreign exchange risk.

12. a. If the foreign currency was instead at a forward premium of 1 percent per year, the interest arbitrageur would earn 5% per year. b. If the foreign currency was at a forward discount of 6 percent per year, it would pay for investors to transfer funds from the higher- to the lower-interest center and lose 4% interest but gain 6% from the foreign exchange transaction, for a net gain of 2% per year.

13. a. At point B, the loss of 1% per year from the forward premium on the foreign exchange transaction on the part of the foreign investor is more than made up by the 2% per year gain from the higher interest rate in our nation.

At point B', the 1% interest loss per year on arbitrage inflow into our nation is less than the 2% per year gain on the forward discount on currency transaction. b.

(ch14)

As arbitrage inflow continues from point B, the positive interest differential in favor of our nation declines and the forward premium on the foreign currency increases.

From B', the interest differential in favor of the foreign country increases and the forward discount on the foreign currency decreases.

14. a. At CIAP, there is no further possibility from increasing returns over and above those that investors can achieve in their own country, but this does not mean that returns in the two countries are equalized.

As proof of this, we can see that in the example given at the end of Section 14.6d, annualized returns remain at 8 percent in London for British investors and are increased from 6 percent to 6.852 for American investors without considering transaction costs and 6.602 percent if we consider transaction costs of 1/4 of 1 percent investing in London. Thus, returns become less unequal as a result of CIA, but are not equalized!

App.1a. a. The U.S. investor will get back ($200,000)(1.015)=$203,000. b. The U.S. investor will get back $203,000+($200,000)(0.00213)= $203,000+$426=$203,426. c. The U.S. investor will get back $205,000+($200,000)(0.0025)= $203,000+$500=$203,500, an overestimation of $74.

Lecture Guide: 1.

This is another important and challenging core chapter.

2.

Since the material in this chapter is rather challenging, five classes may be required to adequately cover it. I would use one class to cover each of sections 2-6.

3.

Section 2 on the purchasing power-parity (PPP) theory is not too difficult and students will find Case Study 2 particularly interesting. The question of with respect to which currency the U.S. dollar is undervalued or overvalued can be very confusing to students because the table follows the British tradition of defining the exchange rate as the price of a unit of the domestic currency with respect to the foreign currency. Confusion can be avoided by keeping in mind that a negative sign in a value in the last column of the table means that the dollar is undervalued with respect to the currency of the foreign nation, while a positive sign refers to the dollar is overvalued.

4.

Section 3 dealing with the monetary approach to the balance of payments and exchange rate determination is not too difficult, except for section 3d on expectations. The three case studies add real world relevance and stimulate students' interest.

5.

Section 4 on the asset market or portfolio balance approach starts with a simple model with only the domestic and the foreign interest rate as the determinants of the demand for the domestic currency, the domestic bond, and the foreign bond, and then extends the model to include expected exchange rate changes, risk premium, real income, prices, and wealth as explanatory variables. Section 15.4c on portfolio adjustments and exchange rates brings it all together but is rather challenging.

6.

Section 5 on exchange rate overshooting can be challenging for students, especially the reason for the overshooting.

Instructor’s Manual

In covering Section 6 on empirical testing of the monetary and portfolio balance models and exchange rate forecasting it is important to clearly point out to the students that even though empirical tests do not support the theories presented in the chapter, this does not mean that the theories are wrong or not useful.

Answer to Problems 1. a.

The rate of inflation in Switzerland from 1973 to 1998 was: 101.3 - 46.6 (101.3+46.6)/2

=

54.7 74

=

0.739 or 73.9%

On the other hand, the rate of inflation in the United States from 1973 to 1998 was: 107.0 – 29.2 (107.0+29.2)/2

=

77.8 68.1

=

1.142 or 114.2%

Thus, the inflation rate in Switzerland minus the inflation rate in the United States from 1973 to 1998 was: 73.9% - 114.2% = -40.3% From 1973 to 1998, the Swiss franc appreciated with respect to the U.S. dollar from 3.1648 Swiss francs per dollar in 1973 to 1.4898 Swiss francs per dollar in 1998 or by 1.4898 - 3.1648 (1.4898+3.1648)/2

b.

=

-1.675 2.3273

=

-0.720 or -72.0%

The relative PPP theory did hold only to the extent that since the rate of inflation was lower in Switzerland than in the United States the Swiss franc appreciated with respect to the U.S. dollar between 1973 and 1998. But the percent appreciation of the Swiss franc with respect to the dollar was much greater than that predicted by the relative PPP. Note that in the above calculations, percentage changes were obtained by the average of the beginning and end values. You may want to ask the class to do the same when assigning this and the next problem so as to get the same answer.

2.

The rate of inflation in Spain from 1973 and 1998 was: 107.5 – 10.1 (107.5+10.1)/2

(ch15)

=

97.4 58.8

=

1.656 or 165.6%

15-3

Dominick Salvatore

International Economics – 11th Edition

Instructor’s Manual

Thus the rate of inflation in Spain minus the rate of inflation in the United States (found in Problem 1a) is: 165.6% - 114.2% = 51.4% From 1973 to 1998, the Spanish peseta depreciated from 58.26 pesetas per dollar in 1973 to 149.40 pesetas to the dollar in 1998 or by:

149.40 - 58.26 (149.40+58.26)/2

=

91.14 103.83

=

0.878 or 87.8%

Since Spain had an inflation rate 51.4 percent higher than the U.S. inflation rate and the Spanish peseta depreciated by 87.8 percent from 1973 and 1998, we can say that the relative PPP theory worked reasonably well between the United States and Spain during this period.

3. a.

Md=kPY=(1/V)(PY)=(1/5)(200)=$40 billion.

b.

If the nation's nominal GDP rises to $220 billion, Md=220/5=$44 billion.

c.

If the nation's nominal GNP increases by 10 percent each year, Md increases also by 10 per cent each year.

4. a.

Monetary base of the nation is, D+F=8+2=$10 billion.

b.

The value of the money multiplier is, m=1/LLR=1/0.25=4.

c.

The value of the nation's total money supply is Ms=m(D+F)=4(8+2)=$40 billion

5. a. b.

Md=Ms and the nation is in balance of payments equilibrium.

Md of $44 billion exceeds Ms of $40 by $4 billion.

With m=4, there will be an inflow of money or international reserves from abroad of $1 billion to equate Ms to Md. Thus, the nation's balance of payments surplus will be equal to $1.

6.

(ch15)

The nation will face a continuous inflow of money or international reserves and balance of payments surplus of $1 billion, year in and year out.

15-4

a.

If monetary authorities do not change the domestic component of the nation's monetary base, the nation's balance of payments disequilibrium is corrected by a once-and-for-all inflow of money or international reserves of $1 billion.

b.

If monetary authorities do not change the domestic component of the nation's monetary base, the nation's balance of payments disequilibrium is corrected by a once-and-for-all inflow of money or international reserves of $1 billion.

c.

If monetary authorities completely sterilize, or neutralize, the balance-ofpayments disequilibrium with a change in the domestic component of the nation's monetary base, the domestic component of the nation's monetary base will fall by an amount equal to the increase in the foreign component of the nation's monetary base so as to leave the monetary base unchanged. This could only go on until the domestic component of the nation's monetary base has dropped to zero.

7.

Md=100/4=25 falls short of Ms=30 and there will be an outflow of international reserves (a deficit in the nation's balance of payments).

8.

According to the monetary approach, inflation in the second nation is caused by excessive money creation there. As a result, either the first nation's exchange rate has to appreciate to keep its balance of payments in equilibrium or its monetary base will rise (so that inflation will spread to nation 1).

9.(a)

The condition for uncovered interest parity is given by i-i*=EA, where EA is the expected appreciation of the pound. That is, since the spot rate of SR=$2.02/£1 in three months is 1% (4% on an annual basis) higher than SR=$2.00/£1 today, the condition for UIA is satisfied because 6%-10% = 4% (with all percentage rates expressed on an annual basis).

(b) If the spot rate is expected to be SR=$2.04/£1 in three months, the pound would be expected to appreciate by 2% for the three months (8% on an annual basis).

Investors would now earn more by investing in London than by investing in New York and the condition for UIA would no longer be satisfied. As more dollars are exchanged for pounds to increase investments in London, the actual spot rate will increase from SR=$2.00/£1 to SR=$2.02/£1. This will leave only an expected appreciation of the pound of about 4% per year (the same as before the change in expectations). This is obtained by comparing the new higher spot rate of SR=$2.02/£1 today with the new expected spot rate of SR=$2.04/£1 in three months, so as to return to UIA parity.

10. (a) The expected change in the exchange rate is part of the uncovered interest parity (UIP) condition (see Equation 15-8). Here investors face a foreign exchange risk in purchasing foreign bonds. On the other hand, the forward discount or premium is part of covered interest arbitrage condition (see Equation 14-1) and investors do not face any foreign exchange risk in purchasing foreign bonds.

(ch15)

15-5

(b)

If the actual change in the exchange rate were always exactly equal to the expected change in the exchange rate, then the expected change in the exchange rate would be equal to the forward discount.

11.

The depreciation of the foreign currency means that the domestic-currency value of foreign bonds has decreased and the nation's residents now hold less of their wealth in foreign bonds than they want. They will, therefore, purchase more foreign bonds. This is stock adjustment that leads to a once-and-for-all increase in the quantity purchased of the foreign currency (to purchase the foreign bonds), which, in turn, leads to an appreciation of the foreign currency that neutralizes in part the original depreciation of the foreign currency.

12.

According to the portfolio balance approach, an increase in the expected rate of inflation in the nation would lead to the expectation that the domestic currency will depreciate and the foreign currency will appreciate under flexible exchange rates. In terms of the extended portfolio balance model, this means that the expected appreciation of the foreign currency (EA) increases. The rise in EA will lead to a reduction in the demand for money balances (M) and the domestic bond (D) and an increase in the demand for the foreign bond (F) by domestic residents (see Equations 15-10 to 15-12). This leads to a depreciation of the domestic currency as domestic residents exchange the domestic for the foreign currency in order to purchase the foreign bond and to other changes in all other variables of the model until equlibrium is reestablisehd in all the markets simultaneously.

13.

The increase in the supply of the foreign bond because of a foreign government's budget deficit increases the risk premium on holdings of foreign bonds by homecountry residents. This reduces the right-hand side of the UIP condition (Equation remaining equal, this leads to a depreciation of the foreign currency and appreciation of the domestic currency as investors switch from foreign to domestic bonds. Furtheremore, if inflation expectations abroad increase because of the budget deficit, this will reinforce the tendency of the foreign currency to depreciate and domestic currency to appreciate. The depreciation of the foreign currency will then make foreign bonds cheaper to home-country residents and this induces them to buy more of them. Portfolio adjustments will continue until equilbrium is reestablished in all markets simultaneously.

14.

The unanticipated increase in the money supply by the U.K. central bank, will lead to an immediate reduction in the British interest rate and a magnified depreciation of the pound (appreciation of the dollar). Over time, as prices and interest rates rise in the United Kingdom, the pound appreciates (dollar depreciates) so as to remove its undervaluation (overvaluation) in order to reach its new long-run equilibrium level.

App. 1.At the beginning of the period: H=D+F=100+20=120, and F/H=20/120 and D/H=100/120 Over the period of the analysis: gD=(10/100)100=10% Rewriting (19A-8) and substituting the values of the problem into it, we get: (F/H)gF=agP+bgY+gu-cgr-gm-(D/H)gD (20/120)gF=0.1+0.04+0-0-0-(100/120)(0.1) (20/120)gF=0.140-0.083 (20/120)gF=0.057 gF=(120/20)(0.057) gF=0.342 Since F=20 at the beginning of the period of the analysis and grows by 34.2% over the period of the analysis, F=20+20(0.342)=20+6.84=26.84 at the end of the period of the analysis.

App. 2 a. An increase in Ms increases the domestic demand for the foreign bond and increases R (i.e., the domestic currency depreciates). This is the same result postulated by the monetary approach. b. A once-and-for-all depreciation of the domestic currency increases the domestic-currency value of the foreign bond (i.e., confers a capital gain to the nation's residents). If they previously held the desired proportion of their wealth in foreign bonds, they would be holding more of the foreign bond than they want after the depreciation. As a result, they would sell some of their holdings of the foreign bond to purchase more of the domestic bonds and the domestic money.

This will cause an appreciation of the domestic currency, which will neutralize in part the previous depreciation. The process ends when equilibrium is simultaneously reestablished in all three markets.

ADDITIONAL ESSAYS AND PROBLEMS FOR PART THREE 1. (a) If, for every debit or credit in the balance of payments, an offsetting credit or debit, respectively, of an equal amount is entered, how can a nation have a deficit or a surplus in the balance of payments? (b) How is a deficit of a surplus in the balance of payments measured? (c) Why are the concepts and measurement of deficit or surplus not appropriate under a flexible exchange rate system? (d) What is the difference between a disequilibrium and a deficit in the balance of payments?

Answ. (a) We have seen that because of double-entry bookkeeping, total credits always equal total debits when the three accounts are summed (including the allocation of SDRs and the statistical discrepancy). However, the deficit or surplus is measured by summing all items in the balance of payments except those in the nation's official reserve account. Only if the net balance on the nation's official reserve account were account were zero would the nations' balance of payments be in equilibrium. (b)If total debits exceed total credits in the current and capital accounts (including the statistical discrepancy), the net debit balance measures the deficit in the nation’s balance of payments. The deficit must be settled (under a fixed exchange rate system) with an equal net credit balance in the official reserve account. On the other hand, if total credits exceed total debits in the current and capital accounts (and the statistical discrepancy), the net credit balance measures the surplus in the nation's balance of payments. This surplus must be settled (under a fixed exchange rate system) with an equal net debit balance in the official reserve account.

All transactions in the current and capital accounts are called autonomous items because they take place for business or profit motive (except unilateral transfers) and are independent of balance of payments considerations. On the other hand, the items in the official reserve account are called accommodating items because they result from and are needed to balance international transactions. Thus, a deficit in a nation's balance of payments is given either by the net debit balance in the nation's autonomous items or by an equal net credit balance in the nation's accommodating items. The opposite is true for a surplus. (c) The concept and measurement of deficit or surplus in the balance of payments are not very appropriate under a freely flexible exchange rate system because of the tendency for a deficit to occur would be prevented by a depreciation of the nation's currency. Under a managed floating exchange rate system, part of the deficit would be corrected by a depreciation of the nations' currency and part would be financed by a net credit balance in the nation's official reserve account.

(d) A disequilibrium refers to an actual or potential deficit. A nation has a potential deficit whenever it imposes import or other restrictions specifically designed to suppress an actual or open deficit. Then the nation is also in disequilibrium.

2.

(a) If the positive interest rate differential in favor of a foreign monetary center is 3 percent per year and the foreign currency is at a forward discount of 1 percent per year, roughly how much would an interest arbitrageur earn from the purchase of foreign three-month treasury bills if he covers the foreign exchange risk? (b) How much would an interest arbitrageur earn if the foreign currency were instead at a forward premium of 1 percent per year? (c) What would happen if the foreign currency were at a forward discount of 3 percent per year?

Answ. (a) The interest arbitrageur will earn 2% per year from the purchase of foreign three- month treasury bills if he covers the foreign exchange risk. (b) If the foreign currency was instead at a forward premium of 1 percent per year, the interest arbitrageur would earn 4% per year. (c) If the foreign currency was at a forward discount of 3 percent per year, it would pay for investors to transfer funds from the higher- to the lower-interest center and lose 2% interest but gain 3% from the foreign exchange transaction, for a net gain of 2% per year.

3.

Explain why according to monetarists (a) nations retain control over their money supply under a flexible exchange rate system but not under a fixed exchange rate system, (b) nations could not sterilize continuous money outflows or inflows under a fixed exchange rate system in order to retain control over their money supply.

Answ. (a) According to monetarists, balance of payments disequilibria are corrected by exchange rate changes without any international flow of money or reserves under a flexible exchange rate system. Thus, the nation retains control over its money supply in the long run. For example, if a nation in balance of payments equilibrium increases its money supply (easy monetary policy), its currency would depreciate and absorb the excess supply of money, without any outflow of money or reserves from the nation. Thus, the increase in the nation's money supply would be retained in the nation. On the other hand, if the nation reduced its money supply (tight monetary policy), the excess demand for money would be eliminated by an appreciation of the nation's currency, without any inflow of money or reserves from the nation. As a result, the nation's attempt to reduce its money supply would succeed.

Under a fixed exchange rate system, the attempt of a nation to increase its money supply and conduct easy monetary policy would simply lead to an outflow of the excess supply of money in the long run, while a nation's attempt to reduce its supply of money and conduct tight monetary policy would simply lead to an outflow of money or reserves. As a result, non-reserve currency nations have little or no control over their money supply in the long run under a fixed exchange rate system. (b) A deficit nation could not sterilize continuous international money flows in the long run under a fixed exchange rate system because the nation would run out of international reserves. On the other hand, a surplus nation would run out of domestic assets backing the nation's money supply. In the long run, a surplus nation would either have to give up its goal of domestic price stability or revalue its currency. This is, in fact, what happened in Germany during the 1960s, when the large inflow of reserves led to some domestic inflation and a revaluation of the mark in 1961 and 1969.

4.

Discuss (a) the exchange dynamics of the dollar resulting from an unanticipated reduction of the U.S. money supply and (b) indicate the final long-run equilibrium interest rate, price index, and exchange rate as compared with the original equilibrium position.

Answ. (a) The unanticipated reduction in the U.S. money supply leads to an immediate increase in the U.S. interest rate and a magnified (i.e., a larger percentage) appreciation of the dollar. Over time, prices and interest rates in the United States all and the dollar depreciates so as to remove the excessive appreciation that took place at the time the U.S. money supply was reduced. (b) At the new long-run equilibrium level, the U.S. interest rate is the same as it was before the reduction of the U.S. money supply. The U.S. price index will be lower by the same percentage by which the U.S. money supply was reduced. The exchange rate will also be lower (i.e., the dollar will have appreciated) by the same percentage by which the U.S. money supply was reduced.

Lecture Guide: 1.

This is an important and challenging core chapter.

2.

I would cover sections 1 and 2 in the first lecture. My experience is that students find particularly difficult the derivation of the demand and supply curves for foreign exchange. Therefore, I would explain the material in sections 16.2a and 16.2b very carefully and slowly. I would also assign problems 1 to 6.

3.

I would cover sections 3 and 4 in the second lecture and pay special attention to section 16.4b. I would also assign problems 7 to 9.

4.

In the third lecture, I would present sections 5 and 6 and assign problems 10 to 15.

Answer to Problems: 1.

The nation's demand curve for imports is derived by the horizontal distance of the nation's supply curve from the nation's demand curve of the tradable commodity at each price below the equilibrium level of the tradable commodity. See Figure 1 on the next page.

2.

The nation's supply curve for exports is derived by the horizontal distance of the nation's demand curve from the nation's supply curve of the tradable commodity at each price above the equilibrium level of the tradable commodity. See Figure 2.

3.

A depreciation of the dollar shifts DM downward vertically and leaves PM (in pounds) and the quantity of imports unchanged (see Figure 3).

4.

A depreciation of the dollar shifts SX downward vertically and leaves PX (in pounds) and the quantity of exports unchanged (see Figure 4).

5.

A depreciation of the dollar reduces the quantity demanded of pounds by less when DM is inelastic (point B in Figure 5) than when DM is elastic (point C).

6.

A depreciation of the pound increases the quantity supplied of pounds by less when SX is inelastic (point B in Figure 6) than when SX is elastic (point C).

7.

SM is infinitely elastic for a small nation because a small nation can demand any quantity of imports without affecting its price; similarly, DX is infinitely elastic because a small nation can sell any amount of its export good without having to reduce its price.

8.

The balance of payments of a small nation always improves with a depreciation or devaluation of its currency because the small nation's quantity demanded of pounds always falls (unless DM is vertical) and the quantity supplied of pounds always rises.

9.

See the two panels of Figure 7 on page 156.

Panel A shows that a devaluation or depreciation of the nation's currency results in downward shift in DM and, by itself, results in a reduction in the quantity demanded of the foreign currency by the nation and thus to an improvement in the nation's balance of payments (trade).

Panel B shows that a devaluation or depreciation of the nation's currency results in a downward shift in SX which, by itself, leads to a net reduction in the quantity of foreign currency earned by the nation through exports and to a worsening of the nation's balance of payments (trade).

Since the reduction in the foreign exchange earnings of the nation exceeds the reduction in the demand for foreign currency by the nation (compare the shaded areas in the two panels of Figure 7), the nations balance of payments (trade) worsens as a result of the devaluation or depreciation, indicating an unstable foreign exchange market.

Although trade need not be balanced bilaterally or even multilaterally (with international private capital flows), the United States can be said to have a trade deficit with Japan because of the size of this trade deficit and the fact that it has persisted for such a long time despite the sharp depreciation of the dollar with respect to the yen during the past decade.

11.

Even though the U.S. trade deficit with Japan has not been reduced as a result of the sharp depreciation of the dollar with respect to the yen during the past 10 years, we cannot conclude that the trade or elasticity approach to balance of payments adjustment does not work. The U.S. trade deficit with Japan seem to respond only with a lag of several years to exchange-rate changes. In addition other forces may have overwhelmed the effect of a depreciation of the dollar with respect to the yen. For example, if Japan is in the contractionary part of the business cycle while the United States at an expansionary part of the cycle, the U.S. trade deficit with Japan may increase because Japan demands fewer American products while the United States demands more Japanese products, despite the depreciation of the dollar vis-avis the yen.

12.

Since $35=1 ounce of gold = £14, the dollar price of £ or the exchange rate (R=$/£) is fixed at $35/14=$2.50. Thus, fixing the price of gold in terms of national currencies under the gold standard establishes a fixed relationship or exchange rate between any two currencies. This is the mint parity.

13.

Since to ship $2.50 worth of gold from New York to London costs 1% or 2.5c, the U.S. gold export point or upper limit of the exchange rate equals $2.50 plus 2.5c or $2.525. The reason for this is that no U.S. resident would pay more than $2.525 to obtain £1, since he could buy $2.50 worth of gold from the U.S. treasury, ship it to the United Kingdom at a cost of 2.5c and sell it to the U.K. treasury for £1.

Thus, under the gold standard, the exchange rate of the pound can never rise above (and the dollar depreciate past) the U.S. gold export point of $2.525.

14.

Similarly, the exchange rate can never fall below (and the dollar appreciate past) the U.S. gold import point of $2.475. The reason for this is that no U.S. resident would accept less than $2.475 for each pound sold, since he could always buy a pound worth of gold from the U.K. treasury at the fixed price, import this gold into the United States at a cost of 2.5c, and resell it to the U.S. treasury for $2.50.

Thus, the U.S. resident can get pounds at $2.475 ($2.50 minus 2.5c) and would not accept less in selling them. Note that the shipping cost of gold includes not only the transportation cost but also all other handling charges, insurance, and the interest foregone while the gold is in transit.

App. 1 N=($PX/$PM)=($4/$2)=2 or 200%.

The results is the same as that obtained in section 16.2b, where PX and PM were both measured in pounds.

App. 2 A depreciation or devaluation of a small country's national currency is not likely to affect its terms of trade because DM and SX are infinitely elastic or horizontal for a small nation, and a depreciation or a devaluation of its currency would leave PM and PX unchanged when measured in terms of either the domestic or the foreign currency.

App. 3 If D£ shifts to D'£ and S£ shifts to S'£ in Figure 16-8, the exchange rate R would be R=$4.86/£1 and the balance of payments would be in equilibrium both under the gold standard and under a flexible exchange rate system.

Multiple-choice Questions: 1. The more elastic is a nation's demand and supply of foreign exchange the: a. larger is the devaluation or depreciation required to correct a deficit of a given size in the nation's balance of payments *b. smaller is the devaluation or depreciation required to correct a deficit of a given size in the nation's balance of payments c. less feasible is a flexible exchange rate system d. less feasible is a devaluation as a policy to correct a deficit in the nation's balance of payments 2. A nation's demand curve for foreign exchange is derived from the: a. foreign demand curve for the nations' exports b. nation's supply curve of exports *c. domestic demand curve for imports and the foreign supply curve for the nation's imports d. foreign demand curve and the domestic supply curve for the nation's exports 3. A depreciation of a nation's currency shifts: a. down its supply curve of imports in terms of the foreign currency b. up its demand curve of imports in terms of the foreign currency *c. down its demand curve of imports in terms of the foreign currency d. down its demand curve of imports in terms of the domestic currency 4. When a nation's demand curve for imports in terms of the foreign currency is vertical: *a. the nation's demand curve for the foreign currency has zero elasticity b. the nation's demand for the currency is elastic c. the nation's supply of the currency is vertical d. the other nation's demand for the nation's currency has zero elasticity

Lecture Guide: 1.

In the first lecture on Chapter 17 (a core chapter), I would cover sections 1 and 2 and assign problems 1 to 4. Section 2 is a review of principles of economics but my experience is that the average student needs it to clearly understand the material in the rest of the chapter.

2.

In the second lecture, I would cover sections 3 and 4 and assign problems 3 to 8. Most other texts do not deal with foreign trade multipliers in any great detail because of the difficulty of deriving them. However, their meaning and use is important and they can s still be discussed without deriving them (their derivation is in section A17.1 of the appendix, which can be made optional for the best and most eager students in the class).

3.

In the third lecture, I would cover sections 5 and 6 and assign problems 9 to 14. These two sections are very important and difficult.

Answer to Problems: 1.

See Figure 1 on the next page.

The equilibrium level of national income is YE = 1,000 and is given by point E at which the C+I function crosses the 45° line.

2. a.

S=-100+0.2Y. The saving function is obtained by subtracting vertically the consumption function from the 45˚ line

b.

See Figure 2.

The equilibrium level of national income is YE = 1,000 and is given by point E at which the positively-sloped S function crosses the horizontal I function.

3.

See Figure 3.

The X-M function would shift up as in Figure 9 without full employment. With full employment, the depreciation will result in inflation and a return to the condition of Figure 8 (i.e., the X-M function would shift up and then down to its original position), unless domestic absorption is somehow reduced.

13.

One reason is that the government sector is not included. Another reason is if the nation is not in equilibrium.

14.

The advantages of automatic over policy adjustment to correct a trade disequilibrium are: (1) adjustment begins to operate even before the problem is recognized; (2) there are no possibilities of policy mistakes; and (3) the adjustment will continue until the trade disequilibrium is entirely eliminated. On the other hand, adjustment policies can only be enacted after the problem is recognized. There are then delays to enact policies and for them to have effect. Thus, by the time adjustment policies become effective the nation may not longer face the problem or may face the opposite problem. Wrong policies can also be adopted.

App. 2. Most petroleum exporting nations, notably Saudi Arabia, Libya, and Kuwait could not spend all of their petroleum earnings on increased imports from petroleum importing countries during the 1970s. Most unspent earnings were used for portfolio purchases in the developed nations, especially in the U.S., through the Eurodollar market. At the same time, most oil-importing nations deflated their economies to reduce their oil bill and balance of payments difficulties. The sharp decline in petroleum since 1981completely eliminated the excess earnings of most OPEC nations so that the transfer problem disappeared.

Lecture Outline: 1.

This is one of the most important and challenging of the chapters. Sections 1-2 and 6-7 are core sections and should be covered in any international economics course. Sections 3-5 introduce the IS-LM-BP model and may be skipped if intermediate macroeconomics is not a requirement for the course. This is up to the Instructor, however.

2.

In the first lecture, I would cover sections 1 and 2 and assign problems 1-3. The most important and difficult part here is the Swan diagram. If students are to know anything about economic policies to correct internal and external imbalances, this is it.

3.

Sections 3-5 require two classes to be covered adequately if students had intermediate macroeconomics. Otherwise, it would take three classes, or they can be skipped. If sections 3-5 are covered, I would assign problems 4-11 and go over some of these in class to make sure that students fully understand the model and the policies that can be used to correct internal and external imbalances.

4.

I would cover section 6 in the next class and assign problems 12-14. The most important aspect of this section is the explicit recognition of price stability as the third important objective of nations and the problems that this creates with the policies at hand to achieve internal and external balance completely. I would also cover Case Studies 18.1-18-3.

5.

I would leave section 7 for students to cover by themselves. The section is important but mostly descriptive and students to read it on their own and bring questions to class.

The nation faces a surplus at YE=1,000 because P is below point E.

b.

At YE=1,000 and with a MPM=0.15, the nation faces a surplus of (200)(0.15)=30.

5.

The nation of problem 4 can reach full employment with external balance with the expansionary fiscal policy that shifts IS upward until it crosses the BP line at point F and the tight monetary policy that shifts LM upward until it also crosses the BP line at point F.

6.

The nation requires the expansionary fiscal that shifts the IS curve up until it crosses the BP curve at point F and the tight monetary policy that shifts up the LM curve until it crosses the BP curve at point F. See Figure 1.

7.

If the full-employment level of national income is YE=1,000, the nation requires the expansionary fiscal policy that shifts the IS curve up until it crosses the BP curve at point B' and the tight monetary policy that shifts up the LM curve until it crosses the BP curve at point B'.

See Figure 2.

8. a.

If the BP curve were flatter than the LM curve, the nation would require the expansionary fiscal policy that shifts the IS curve up until it crosses the PB curve at point F and the easy monetary policy that shifts down the LM curve until it crosses the BP curve at point F. See Figure 3.

Instructor’s Manual

When the BP curve is flatter than the LM curve, the nation requires an easy rather than a tight monetary policy to achieve internal and external balance simultaneously.

With perfectly elastic international capital flows, the BP line would be horizontal and monetary policy would be completely ineffective. The nation could reach internal and external balance with the appropriate expansionary fiscal policy only.

Starting from point E in Figure 18-8 in the text, the nation could use the fiscal policy that shifts the IS curve to IS', intersecting the LM curve at point Z (see Figure 4 on the next page). Since point Z is to the right of the BP curve, the nation will have a deficit in its balance of payments. With flexible exchange rates, the nation's currency depreciates and so the BP curve shifts to the right. This induces a leftward shift in the LM curve to LM', such that curve IS" and LM' intersect on the BP curve at point E'. Since at point E' the nation still faces unemployment, the nation would need to apply additional doses of expansionary fiscal policy until all three markets are in equilibrium at the full-employment level of national income of YF = 1500.

11.

Starting from point E in Figure 18-8 in the text, the nation could use the fiscal policy that shifts the IS curve to IS' (see Figure 5 on the next page), intersecting the LM curve at point Z. Since point Z is now to the left of the BP curve, the nation will have a surplus in its balance of payments. With flexible exchange rates, the nation's currency appreciates and so the BP curve shifts to the left. This induces a leftward shift in the IS curve to IS" and a rightward shift in the LM curve to LM', such that curve IS" and LM' intersect on the BP curve at point E'.

Since at point E' the nation still faces unemployment, the nation would need to apply additional doses of expansionary fiscal policy until all three markets are in equilibrium at the full-employment level of national income of YF = 1500.

An unexpected increase in prices in the face of sticky wages means that real wages temporarily fall. This leads firms to hire more workers and thus increase output in the short run. In the long-run, however, money wages fully adjust to (i.e., increase in the same proportion as) the increase in prices. As a result, real wages return to their previous higher level, firms reduce employment to their original lower level, and the nation's output returns to its lower long-run natural level, but at the new higher price level.

6.

Starting from point C in Figure 19-3, an unexpected decrease in aggregate demand from AD' to AD causes prices to fall and firms to temporarily reduce their output, giving the new short-run equilibrium point where the AD' curve intersects the SRAS' curve. In the long run, however, as expected prices fall to match actual prices, the short-run aggregate supply curve shifts down by the amount of the price reduction (i.e., from SRAS' to SRAS) and defines new longrun equilibrium point E at the natural level of output YN, but lower price level of PE. Another way of saying this is that at point to the left of the LRAS curve, actual prices are lower than expected prices. Expected prices then fall and this shifts the SRAS curve downward until expected prices are equal to the lower actual prices, and the economy returns to its long-run natural level of output equilibrium.

7.

An unexpected decrease in aggregate demand causes prices to fall. If wages are sticky and do not immediately fall in the same proportion as the fall in prices, real wages will temporarily increase. This leads firms to hire fewer workers and thus reduce output in the short run. In the long-run, however, money wages fully adjust to (i.e., fall in the same proportion as) the fall in prices. As a result, real wages return to their previous lower level, firms increase employment to their original higher level, and the nation's output returns to its higher long-run or natural level, but at the new higher lower level.

8.

If the LM' curve intersected the IS' curve at a point below the BP' curve in the left panel of Figure 19-5, the interest rate in the nation would be lower than required for balance of payments equilibrium. The nation would then have a deficit in its balance of payments. Under a fixed exchange rate system, the deficit in the nation's balance of payments would result in an outflow of international reserves and thus a reduction in the nation's money supply, which would shift up the LM' curve sufficiently to intersect the IS' curve on the BP' curve, so that the nation would be simultaneously in equilibrium in the goods and money markets and in the balance of payments, as at point E".

10.

Starting from equilibrium in the goods and services sector, in the monetary sector, and in the balance of payments, an autonomous worsening of the nation's trade balance at unchanged domestic prices, causes the IS and BP curves to shift to the left and opens a deficit in the nation's balance of payments under fixed exchange rates. This leads to a leftward shift of the LM curve and a reduction in national income. Thus, the nation's aggregate demand curve shifts to the left.

11.

With flexible exchange rates, the autonomous worsening of the nation's trade balance at unchanged domestic prices, causes the IS and BP curves to shift to the left (just as in the case of fixed rates). Now, however, the tendency of the nation's balance of payments to go into deficit leads to a depreciation of the nation's currency and a deterioration in the nation's trade balance, so that the BP and IS curves shift to the left, back to their original position along the unchanged LM curve. Thus, the nation returns to the original equilibrium position and point on its original aggregate demand curve.

12.

Expansionary fiscal policy under fixed exchange rates or easy monetary policy under flexible rates can correct a recession but only the expense of higher prices or inflation. If prices are flexible downward in the nation, however, the recession can be corrected automatically and in a relatively short time by falling domestic prices, which would stimulate the domestic and foreign demand for the nation's goods and services. If domestic prices are sticky or not too flexible downward, however, relying on market force (i.e., falling prices in the nation) to automatically correct the recession may take too long, and this may justify the use of expansionary fiscal or monetary policies.

The nation would reach the long-run equilibrium point where the AD' curve crosses the unchanged LRAS curve. The SRAS curve would also shift and cross the LRAS curve at the same point. The nation's natural level of output and employment would then be the same as before the supply (petroleum) shock, but prices would be higher.

14.

The concept of the natural rate of unemployment is useful as long as no structural changes take place in the economy. When structural changes do occur (and globalization may just be such a structural change), then the rate of natural unemployment will change. With globalization the natural rate of unemployment may well be 5 percent or lower in the United States today.

But it also examines the European Monetary System and international macroeconomic cooperation. It is an important chapter but because of the time constraint, I would omit it in a one-semester undergraduate course in international economics, except for section 20.4 on the European Union and the short section on international macroeconomic policy coordination.

2.

If I were to cover this chapter, I would cover sections 1 to 3 in the first lecture, section 4 in the second lecture, and sections 5 and 6 in the third lecture and assigning the end of chapter problems.

Answers to Problems: 1. a. b.

The U.S. will export the commodity because at R=2, P=$7 in the U.S. and P=$8 in the U.K. The U.S. has a comparative disadvantage in this commodity at the equilibrium exchange rate.

2.

Under a fixed exchange rate system and perfectly elastic international capital flows, the attempt on the part of the nation to reduce its money supply (tight monetary policy) tends to increase interest rates in the nation and attract capital inflows. This frustrates the attempt on the part of the nation's monetary authorities to reduce the nation's money supply. On the other hand, the attempt of the nation's monetary authorities to increase the money supply of the nation will be frustrated by the tendency of the nation's interest rate to fall, resulting in a capital outflow that would leave the nation's money supply unchanged (see section 17.4c).

An optimum currency area involves permanently fixed exchange rates as well as common monetary and fiscal policies among its members. Thus, an optimum currency area resembles a single economic entity and monetary union. There are no such implications for countries which are connected only by fixed exchange rates.

7. (a) With a single central bank and currency the member nations of the European Union can no longer print money and thus each member no longer has the wherewithal to conduct monetary policy. The original central bank of each member nation now assumes functions similar to that of the federal reserve banks in the Federal Reserve System in the United States. That is, they affect the community-wide monetary policy only through their participation in central bank deliberations and decisions. (b) With a single currency, of course, there are no such things and exchange rates among the member nations' currencies, just as there are no exchange rates for the dollar among the states of the United States. Or better, the exchange rate is permanently fixed at 1:1.

8.

The benefits that the EU would get from establishing a single currency are: eliminating the costs involved in exchanging currencies, eliminating the risk of exchange fluctuations and currency crises, inducing nations to adopt more appropriate economic policies and being able, as a community, to withstand better external shocks. The costs results from the inability of nations to change their exchange rate and to tailor monetary and fiscal policies to their specific national needs.

9. (a) Under a fixed exchange rate system a nation rigidly fixes the exchange rate and prevents it from changing by losing or accumulating international reserves. (b) Under a currency board arrangement (CBA), the nation rigidly fixes the exchange rate and its central bank loses its ability to conduct an independent monetary policy by allowing the nation’s supply of money to increase or decrease only in response to its balance of payments deficits or surpluses. (c) With dollarization a nation adopts another nation’s currency as its legal tender.

It is true that flexible exchange rates tend to insulate the economy from international disturbances. For example, the tendency of a nation to follow inflationary policies will result in a depreciation of its currency. This means that the trade partner's currency will appreciate, making its imports cheaper and thus preventing the importation of inflation from abroad.

In an integrated world capital market, however, inflationary policies by one nation will lower its interest rates in the nation and will lead to capital outflows. Unless the trade partner is able to continuously sterilize these capital inflows, inflationary pressures will spread to it also. These inflationary pressures can be avoided by international policy coordination. Thus, international policy coordination is useful also under a flexible exchange rate system because in a world of unrestricted international capital flows flexible exchange rate do not insulate nations completely from their partner's policies.

13.

Game theory is a method for examining the effect of a given policy or course of action on a nation or other economic unit for each possible response by another nation or other economic unit. Game theory can thus be used to show that a cooperative equilibrium can be better for (i.e., can increase the welfare of) each nation or economic unit than if each tries to maximize its welfare independently.

14.

In a noncooperative equilibrium, each nation is likely to follow a loose fiscal policy but a tight monetary policy in order to keep its interest rates up and thereby attract foreign capital and keep the international value of its currency high, so as to keep import prices low. However, when all nations do this their efforts will be self-defeating and interest rates will be higher than with a cooperative equilibrium. High interest rates will reduce long-term growth for all nations. With a cooperative equilibrium, on the other hand, nations will use restrictive fiscal and easy monetary policies. This will keep interest rates low and thus stimulate longrun growth.

15. (a) There have been four episodes of significant international macroeconomic policy coordination among the leading industrial nations during the past three decades.

The first occurred in 1978 when Germany was induced to stimulate its economy and play as "locomotive" and stimulate growth in other leading industrial countries also. The effort ended when Germany, fearing inflation, stooped stimulating its economy. The second was the Plaza Agreement in September of 1985 when the United States, Japan, Germany, France, and the United Kingdom met at the Plaza Hotel in New York to engineer a "soft landing" for the overvalued dollar. This effort was regarded as successful but the markets were already lowering the value of the dollar. The third case is represented by the Louvre Accord in February 1987, when the leading industrial nations agreed on implicit target zones for the exchange rates among the leading currencies. This agreement, however, became inoperative soon after it was reached. The fourth case is evidenced by the coordinated quick monetary response on the part of the United States, Germany, and Japan to October 1987 worldwide equity-market crash. (b) International macroeconomic policy coordination to date has been episodic and limited in scope and it is unlikely that it will be very different in the future.

App. On Janaury 1, 1999, 11 of the 15 members of the European Union adopted the euro as their common currency. Britain, Sweden, and Denmark decided not to join from the start, but retained the option to join later. Greece was not admitted because of its inability to meet most of the Maastricht criteria. The likelyhood, however, is that all four will join the euro by July 2002, when the euro is to completely replace the currencies of the participating nations. In the meantime, a new exchange rate mechanism, the ERM II, was installed to keep the currencies of these four countries from fluctuating to widely, in anticipation of their joining the euro.

Lecture Guide: 1.

This core chapter examines the operation of the international monetary system from the gold standard to the present managed exchange rate system, using the theoretical analyses of the previous chapters as background. It also examines proposals for reforms.

2.

I would cover two sections in each of three lectures and assign the end-of-chapter problems.

3.

I would use each lecture to show the relevance and importance of the analysis of previous chapters in analyzing and evaluating the operation of the various adjustment mechanisms discussed throughout the semester. Indeed, this will also serve a summary review of the course for the final.

Answers to Problems: 1. a.

(ch21)

The primary goal of nations today is internal balance, while during the heyday of the gold standard nations gave priority to external balance. The gold standard days were also characterized by much greater price flexibility than today. Furthermore, London was then the undisputed center of international trade and finance and as a result, there were no destabilizing international capital flows, as frequently occur today between the different International monetary centers.

Instructor’s Manual

The reestablishment of the gold standard today would require the reestablishment of all the conditions that made for its smooth operation from 1880 until 1914. Nations would have to place priority on external over internal balance and give up their use of monetary policy. They would have to eliminate domestic restrictions on price flexibility (i.e., abolish price ceilings, minimum wages, interest restrictions, etc.), and reestablish the supremacy of one international monetary center (New York, Tokyo, or London) so as to avoid destabilizing capital flows among the international monetary centers in existence today. Needless to say, this is impossible.

The nation was to pay 25% of its quota ($25 million) in gold and the remainder in the nation's currency. Under the original rules, the nation could borrow no more than 25% of its quota ($25 million for this nation) from the Fund in any one year.

Today, the nation would pay 25 percent of its quota in SDRs or in currencies of other members selected by the Fund, with their approval, and the rest in their own currency.

Under the new rules in operation today, the nation can borrow a maximum of up to 150 percent of its quota in any one year under the various programs to facilitate borrowing that the Fund has put in place over the years.

3.

In order to borrow $25 million, the nation of problem 2 would pay into the Fund another $25 million of its currency. The nation would then receive an equal amount of a reserve currency (usually dollars). The nation could borrow this so-called this gold (now, the reserve or first credit) trance automatically.

4.

The nation of problem 2 could continue to borrow $25 million in each of the four subsequent years under the original rules. During each year, the nation would deposit an additional $25 million of its currency with the Fund in exchange for an equal amount of a reserve currency.

After 5 years, the nation will have borrowed a total of 125% of its quota under the original rules so that the Fund would hold 200% of the nation's quota in the nation's currency (75% deposited when the nation joined the Fund and 125% from borrowing).

With each additional amount borrowed, the Fund imposes more conditions and supervision.

5.

The nation was to repay its loan by "repurchasing" its currency from the Fund with other convertible currencies approved by the Fund, until the Fund once again held no more than 75% of the nation's quota in the nation's currency. The fund allows repayment to be made in currencies of which the Fund holds no more than 75% of the issuing nation's quota. Repayment was originally to be made within 3 to 5 years.

6.

Nation A will only have to repay $15 million (for the Fund to hold no more than 75% of nation A's quota in nation A's currency).

The nation could attempt to discourage large destabilizing international capital flows by purchasing the foreign currency forward to reduce the forward discount or increase the forward premium on the foreign currency.

b. The same is true today, except that today exchange rates can fluctuate much more than under the Bretton Woods System and capital moves much more freely internationally than under the old Bretton Woods System, so that the policy of intervening in the forward market is likely to be much less effective.

8. a. The nation could attempt to discourage large destabilizing international capital flows by purchasing the foreign currency in the spot market. This tends to appreciate the foreign currency and discourage international capital inflows. b. The same is true today, except that today exchange rates can fluctuate much more than under the Bretton Woods System and capital moves much more freely internationally than under the old Bretton Woods System, so that the policy of intervening in the spot market is likely to be much less effective.

9.

Under the Bretton Woods system, the dollar was truly an international currency. From about the mid-sixties until the collapse of the system in 1971, however, foreigners became progressively more reluctant to hold dollars as the amount of officially foreignheld dollars became progressively higher than U.S. gold reserves. Some other "strong" currencies such as the German mark also began to be widely held as international reserves. But the dollar remained by far the most widely-held international currency.

10. a. The immediate cause of the collapse of the Bretton Woods system was the demand on the part of some European central banks to convert some of their dollar holdings into gold. Had the United States done so, others would have demanded gold for dollars, soon exhausting all U.S. gold reserves. Thus on August 15, 1971, the U.S. suspended the convertibility of dollars into gold. This put the world on a pure paper (dollar) standard. b. The fundamental cause of the collapse of the Bretton Woods system was the lack of an adequate adjustment mechanism as nations were very reluctant to change their par value when in fundamental disequilibrium. They relied instead on a web of ad hoc measures which in the end became unwieldy and inadequate for the task.

11.

The present international monetary system is a managed floating exchange rate system with nations intervening in the foreign exchange markets to smooth out excessive fluctuations in exchange rates. Thus, there is still a need for international reserves. The dollar (without any backing to gold) remains the most important international currency.

12. a. The fundamental reason for the Mexican currency crisis was that Mexico relied on keeping an overvalued exchange rate that would lead to a trade deficit and thus a capital inflow to help finance investments and growth. This worked fine until the middle of 1994 (ch21)

21-4

Dominick Salvatore

International Economics – 11th Edition

Instructor’s Manual

when investors began to doubt Mexico’s ability to repay foreign loans and thus withdrew their capital. This caused the international value of the Mexican pesos to fall sharply (i.e., to depreciate very heavily with respect to the dollar), inflation and interest rates to rise sharply, and the nation to plunge into deep recession. b. The IMF proposed to avoid the recurrence of a Mexican-style currency crisis by setting up an early-warning system for developing countries to provide accurate and timely financial data so that investors can anticipate problems before they become crises and by negotiating a doubling to $47 billion of the amount that it could borrow under the (New) General Agreement to Borrow in order to provide financial assistance to those nations that do face a serious financial crisis.

13. a.

The Mexican currency and financial crisis taught developing nations that they cannot rely excessively on short-term capital inflows (which can as quickly flow in as flow out) to finance growth and development. They should instead try to increase domestic savings and encourage long-term capital inflows. Second, in the face of a financial crisis, it is better to deal with the crisis quickly and decisively.

b. Another lesson from the Mexican crisis is that when a currency and financial crisis does hit, it is best to nip it in the bud and take immediate and bold action to overcome it. For example, if Mexico had devalued the pesos in April or even September 1994 when its international reserves were still plentiful, the crisis would probably not have been as deep and serious as it became.

14. a. All the economic crises in emerging market economies during the second half of the 1990s started with a massive withdrawal of short-term liquid funds at the first sign of financial weakness in the nation. Foreign investors poured funds into many emerging markets during the 1990s in order to take advantage of high returns and to diversify their portfolio after these nations liberalized their capital markets, but they quickly got out of the country as soon as they began to fear that an economic crisis was imminent. This was the case in each of the four emerging market crises: Mexico in 19945, South-East Asia in 1997-1999, Russia in summer 1998, and Brazil in 1999. b. Proposed solutions to avoid future crises in emerging market economies include: Avoid over borrowing of short-term funds (2) increased transparency in financial relations, (3) strengthening emerging markets’ (4) banking and financial system, and (5) greater private sector involvement in rescue programs.

15.

(ch21)

The most important international monetary problems facing the world today are: (1) trade protectionism in advanced countries; (2) large exchange rate volatility and disequilibria, (3) frequent economic crises in emerging market economies (4) job insecurity and stagnant wages in the United States and other advanced countries (5) high structural unemployment and slow growth in Europe and stagnation in Japan (6) restructuring challenges of transition economies, and (7) deep poverty in many developing countries..

App. a. See Table 1 below. b.

International liquidity measured by the ratio of the dollar value of international reserves (with gold reserves measured at market values) to the total dollar value of world imports declined over the years from 0.80 in 1950 to 0.31 in 1970, it rose to 0.35 in 1985, declined to 0.24 in 1995, it rose to 0.76 in 2009, and it was 0.68 in 2011.

c.

While there is still a need for international reserves under the present system, it is much smaller than it was under the Bretton Woods system. Thus, there seems to be an excess of liquidity in the world today.

ADDITIONAL ESSAYS AND PROBLEMS FOR PART FOUR

1.

Explain the meaning of the J-curve effect and exactly how it works.

Answ. The J-curve effect refers to the deterioration in a nation's trade balance that may result immediately after a devaluation or depreciation of its currency. Only with the passage of time, the nation's trade balance is likely to improve. This is due to the tendency of the domestic-currency price of imports to rise faster than export prices soon after the devaluation or depreciation, with quantities initially not changing very much. With import prices rising faster than export prices and with export and import quantities not changing very much, this means that the nation's expenditures on imports initially increases more than its earning from exports. As a result, the nation's trade balance is likely to deteriorate soon after it devalues or allows its currency to depreciate.

Over time, the quantity of exports rises and the quantity of imports falls and export prices catch up with import prices, so that the initial deterioration in the nation's trade balance is halted and then reversed. Economists have called this tendency of a nation's trade balance to first deteriorate before improving as a result of a devaluation or depreciation in the nation's currency the J-curve effect. The reason is that when the nation's net trade balance is plotted on the vertical axis and time is plotted on the horizontal axis, the response of the trade balance to devaluation or depreciation looks like the curve J.

2.

Suppose that a nation is at full employment without inflation but has a deficit in its balance of payments. (a) Explain why a depreciation of the nation's currency will not correct the deficit unless real output rises or domestic expenditures (absorption) fall. (b) How can the nation's output rise as a result of the depreciation? (c) How can domestic absorption fall automatically as a result of the depreciation? (d) How can the government help reduce domestic absorption and make the devaluation effective?

Answ. (a) A depreciation of the nation's currency stimulated the nation's exports and its production of import substitutes. Unless real output can somehow be expanded and/or domestic absorption reduced, however, this will lead to excess aggregate demand. The resulting inflation will then wipe out the price advantage of the devaluation and the deficit will remain uncorrected. (b) Even if the nation is already at full employment, a depreciation of the nation's currency could lead to higher real national output through the better utilization and the more economic allocation of existing resources. Though possible, this is by no means certain or sufficient. Thus, for a depreciation to be effective, domestic absorption must fall.

(c) Domestic absorption can fall automatically as the nation's currency depreciates because of a real cash balance effect, money illusion, and redistributive effect. The real cash balance effect operates as follows: When a nation's currency depreciates, domestic prices rise; if the money supply remains constant, real cash balances fall and can be replenished only by reducing consumption or absorption. The money illusion cuts absorption if consumers spend less when prices rise, even though their income has also risen. Finally, absorption falls if the depreciation redistributes income to consumers with higher marginal propensities to save. These effects, however, may be inoperative or insufficient. (d) The government can help reduce domestic absorption (and allow the depreciation to be effective) by adopting expenditure-switching or demand policies

Suppose a nation faces domestic unemployment and a surplus in its balance of payments. (a) Explain in detail the expenditure-changing policies required to cure the unemployment. (b) What would happen to the nation's external balance? Why? Answ. (a) Domestic unemployment can be corrected with expenditure- or demandincreasing policies. These refer to expansionary fiscal and monetary policies.

Expansionary fiscal policy refers to an increase in government expenditures and/or a reduction in taxes. A reduction in taxes leads to an increase in consumption which, as for an increase in government expenditures, results in a multiple expansion in national income. On the other hand, easy monetary policy refers to an increase in the money supply and reduction in interest rates. These stimulate investment and also result in a multiple expansion of national income. (b) If domestic unemployment was accompanied by a surplus in the nation's balance of payments, the expansion in national income (to eliminate unemployment) induces a rise in imports, and the reduction in interest rates (from the easy monetary policy) may lead to a larger short-term capital outflow (or reduced inflow), both of which reduce the surplus. Sometimes the original surplus could even turn into a deficit.

This is more likely to occur when the original surplus is small, unemployment is large (so that strongly expansionary fiscal and monetary policies are needed), the marginal propensity to import is high, domestic prices rise as the economy approaches full employment, and capital movements readily respond to the fall in the interest rate. Only rarely and by coincidence will the elimination of unemployment also lead to complete external balance.

Explain why according to monetarists (a) nations retain control over their money supply under a flexible exchange rate system but not under a fixed exchange rate system, (b) nations could not sterilize continuous money outflows or inflows under a fixed exchange rate system in order to retain control over their money supply.

(a) According to monetarists, balance of payments disequilibria are corrected by exchange rate changes without any international flow of money or reserves under a flexible exchange rate system. Thus, the nation retains control over its money supply in the long run. For example, if a nation in balance of payments equilibrium increases its money supply (easy monetary policy), its currency would depreciate and absorb the excess supply of money, without any outflow of money or reserves from the nation.

Thus, the increase in the nation's money supply would be retained in the nation. On the other hand, if the nation reduced its money supply (tight monetary policy), the excess demand for money would be eliminated by an appreciation of the nation's currency, without any inflow of money or reserves from the nation. As a result, the nation's attempt to reduce its money supply would succeed.

Under a fixed exchange rate system, the attempt of a nation to increase its money supply and conduct easy monetary policy would simply lead to an outflow of the excess supply of money in the long run, while a nation's attempt to reduce its supply of money and conduct tight monetary policy would simply lead to an outflow of money or reserves. As a result, non-reserve currency nations have little or no control over their money supply in the long run under a fixed exchange rate system. (b) A deficit nation could not sterilize continuous international money flows in the long run under a fixed exchange rate system because the nation would run out of international reserves. On the other hand, a surplus nation would run out of domestic assets backing the nation's money supply. In the long run, a surplus nation would either have to give up its goal of domestic price stability or revalue its currency.

This is, in fact, what happened in Germany during the 1960s, when the large inflow of reserves led to some domestic inflation and a revaluation of the mark in 1961 and 1969.

Explain what are the benefits and costs for a European nation contemplating joining the European Monetary Union.

Answ. There are some major benefits that the nation can expect to get from joining the monetary union. The nation will no longer have to exchange its currency for that of the other union members and, of course, will no longer have to worry about exchange rate volatility or misalignments with respect to other members. The nation can expect greater and faster economic and financial integration with the other union members and to participate in deciding union wide monetary and other policies. The nation will also be able to undertake domestic policies that are important for its future growth and wellbeing, but which would be political impossible if the nation remained outside the union. The nation will also share in the seigniorage that results from issuing the currency, face lower borrowing costs, and share in the political importance of belonging to a large economic and monetary union.

(ch21)

The most serious problem resulting from joining the monetary union is that the nation will lose complete control over its money supply and exchange rates. As result, in case of a recession, the nation cannot adopt an expansionary monetary policy and/or allow its currency to depreciate (so as to stimulate exports and discourage imports and thus stimulate domestic production). It is true that in a world of open capital markets, the nation would have limited monetary and exchange rate policy independence, but by joining the monetary union it loses all monetary and exchange rate policy independence.

This is a serious shortcoming because labor mobility out of the nation in recession and fiscal redistribution in favor of the nation n are very limited in the European Union as compared, for example, with the United States.

Explain why the establishment of a freely-flexible exchange rate system is unlikely today.

Answ. Under a freely flexible exchange rate system, exchange rates are determined exclusively by the forces of demand and supply without any foreign exchange market intervention on the part of monetary authorities. Under such a self-adjusting system, the need for international reserves would virtually disappear and monetary authorities could devote most of their energies to achieve internal balance. At least, this is how a freelyflexible exchange rate system was supposed to operate. In reality, huge international capital flows rob the nation of most of its monetary independence. Huge international capital flows are also likely to lead to excessive volatility of exchange rate. Exchange rates could also become grossly misaligned for long periods of time. This would seriously distort the pattern of world trade and specialization. As a result, it is rather unlikely that the present managed exchange rate system will evolve in a truly freely flexible exchange rate system. Indeed, it is more likely that more restrictions will be imposed in the future on exchange rate fluctuations.

7. Discuss the causes and effects of the recent global financial crisis in view of what you learned in this course.

The recent global financial crisis had four basic causes: (1) financial regulations were not adequate, especially in the investing banking sector, (2) the financial regulations that did exist were not applied, (3) greed (profits at all costs by bankers and other financial specialists), and (4) fraud (e.g. Madoff’s Ponzi scheme involving $65 billion). The crisis resulted in the “great recession”(the deepest of the post war period) in advanced economies and in many emerging market economies in 2009. Table 16-5 shows that in 2009 real GDP fell by 2.5 percent in the United States, 4.1 percent in the Euro Area, 4.9 percent in the U.K., and 5.2 percent in Japan among advanced economies in the G-20. It fell by 7.9 percent in Russia, 6.5 percent in Mexico, and 4.7 percent in Turkey in 2009 (China and India only suffered a slow-down from the very rapid growth of previous years) among emerging market economies in the G-20. Growth resumed in 2010 in most countries, but remained anemic in advanced economies, as opposed to most emerging market economies.
