LECTURE GUIDE 1.

As the first chapter of the text, the general aim here is simply to define the field of study of international economics and point out its importance in today's globalized world.

2.

The material in this chapter can be covered in two classes. I would utilize one class to cover Sections 1 and 2 and the second class to cover Sections 3 to 7. I would spend most of the second class on Section 6 to identify the major current international economic problems facing the United States and the world and to show how international economics can suggest ways to solve them. This should greatly enhance students' motivation.

ANSWERS TO REVIEW QUESTIONS AND PROBLEMS 1.

Globalization refers to the openness and the free exchange of goods, services, resources, technologies, capital, and ideas around the world. Globalization is important because it increases efficiency; it is inevitable because international competition requires it. The anti-globalization movement blames globalization for increased world poverty and income inequalities, child labor, environmental pollution and many other problems.

2.

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 of goods, services and resources may involve receipts and payments in different currencies, which may change in value in relation to one another through time. International relations are to be contrasted with the interregional relations, 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.

3.

A rough measure of the degree of economic interdependence of a nation with the rest of the world is given by the ratio or percentage of its exports to its gross domestic product (GDP). For small, developed nations, such as the Netherlands and Belgium, the ratio can reach as high as 60 to 90. For large nations, such as Germany, England, France and Italy, the ratio ranges from 25 to 35. For the United States it is between 12 and 17 and growing.

4.

The United States relies less on international trade for its high standard of living than most other developed nations because it is continental in size with immense natural and human resources. As such, it can produce with relative efficiency most of the products it needs. Contrast this to the position of a small nation, such as Switzerland, which can specialize and export only a small range of commodities and imports all the others. In general, and as Figure 1.1 in the text shows, the larger the nation the smaller its economic interdependence with the rest of the world is.

5.

Even though the United States relies only to a relatively small extent on international trade, a significant part of its high standard of living depends on it. The United States must import many commodities that it cannot produce and several needed minerals that it does have. More important quantitatively to its economic well-being, however, are the many commodities that the United States could produce domestically but only at relatively higher cost.

6.

The benefit that the United States receives from immigration is the inflow of skilled workers and technical people that are required for continued high growth in the future without the cost of training them. The cost is that many unskilled people also migrate that lower wages and job opportunities with low-skilled Americans.

7.

International capital flows arise from the opportunities that they provide for higher returns and risk diversification for individuals and corporations, and for nations to borrow or lend to other nations.

8.

The most serious international trade problem facing the world today is the rising protectionism in advanced countries in the context of a rapidly globalizing world. The most serious inter- national monetary problems are the excessive volatility of exchange rates and their large and persistent misalignments, as well as the frequent international financial crises. Other serious international economic problems are the slow growth in Europe and Japan and the need for economic restructuring in these areas and in the former communist countries of Central and Eastern Europe, the deep poverty in developing countries, and the sustainability of continued world growth and development in the face of resource scarcity and environmental degradation and climate change.

9.

The most important international institutions are: --World Trade Organization (WTO) with authority over international trade in goods and services.

--World Bank, which provides loans to developing countries for development programs.

--International monetary Fund (IMF), which oversees international finance and provides loans to nations in temporary balance of payments difficulties.

--United Nations (UN) with stated aims are to facilitate cooperation in international law international security, economic development, social progress, and human rights issues.

10.

The major problems facing the world today affect the United States are: (1) Trade controversies between with Europe, Japan, and China as a result of the globalization of the world economy. These can lead to trade restrictions or even trade wars, which would reduce the volume and the gains from trade and investments for the United States; (2) volatility and misalignments of exchange rates discourage foreign trade and investments, and thus reduce specialization in production and the benefits from trade, and can lead major trade disagreements and protectionism; (3) financial crises in emerging market economies could spread to the United States (as

.

Salvatore’s Introduction to International Economics, 2nd Edition

Instructor’s Manual

financial crises in the United States spread to the rest of the world ); (4) structural unemployment and slow growth in Europe, stagnation in Japan, and insufficient restructuring in the former communist countries in Central and Eastern Europe reduce U.S. imports and the benefits from trade for the United States; (5) deep poverty in many developing nations in the world can lead to political instability and wars, and these would adversely affect the United States and other countries; (6) resource scarcity, environmental degradation, and climate change endanger sustainable development in developing countries and growth in advanced countries, and harm the United States both directly and indirectly in our interdependent and globalized world.

The major problems facing the world today affect you personally as follows: (1) Trade controversies can lead higher prices for imported products; (2) volatility and misalignments of exchange rates lead to great fluctuations and increases in the price of imported products and in the cost of foreign travel; (3) financial crises in emerging market economies can lead to losses on your foreign investments (such as on your pension plans); (4) structural unemployment and slow growth in Europe, and stagnation in Japan reduce European and Japanese imports and increases the chances that you will have to change job; (5) job insecurity and stagnant wages in the United States can lead you to support demands for trade protection in the United States; (6) deep poverty in many developing nations in the world can result in your paying higher taxes to provide foreign aid to these nations; (7) resource scarcity, environmental degradation, and climate change endanger sustainable development in developing countries and growth in advanced countries, and they are causing price of gasoline, food and other products that you pay to rise.

LECTURE GUIDE 1.

This is a long and crucial core chapter and may require four classes to cover adequately. In the first lecture, I would present Sections 1-4 and assign review questions 1-3.

2.

In the second lecture of Chapter 2, I would concentrate on Sections 5-6 and carefully explain the law of comparative advantage using simple numerical examples, as in the text. Both sections are crucial. Section 5 explains the law of comparative advantage and Section 6 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 4-7.

3.

In the third lecture, I would cover Sections 7-9 and assign Problems 8-10.

4.

In the fourth lecture, I would Section 10 and go over problems 4-10. The appendixes could be made optional for the more enterprising students in the class.

ANSWERS TO REVIEW QUESTIONS AND PROBLEMS 1.

The mercantilists believed that the way for a nation to become rich and powerful was to export more than it imported. The resulting export surplus would then be settled by an inflow of gold and silver and the more gold and silver a nation had, the richer and more powerful it was. Thus, the government had to do all in its power to stimulate the nation’s exports and discourage and restrict imports. However, since all nations could not simultaneously have an export surplus and the amount of gold and silver was fixed at any particular point in time, one nation could gain only at the expense of other nations. The mercantilists thus preached economic nationalism, believing that national interests were basically in conflict.

Adam Smith, on the other hand, believed that free trade would make all nations better off.

All of this is relevant today because many of the arguments made in favor of restricting international trade to protect domestic jobs are very similar to the mercantilists arguments made three or four centuries ago. That is why we can say that “mercantilism is alive and well in the twenty-first century”. Thus we have to be prepared to answer and demonstrate that these arguments are basically wrong.

2.

According to Adam Smith, the basis for trade was absolute advantage, or one country being more productive or efficient in the production of some commodities and other countries being more productive in the production of other commodities.

The gains from trade arise as each country specialized in the production of the commodities in which it had an absolute advantage and importing those commodities in which the nation had an absolute disadvantage.

Adam Smith believed in free trade and laissez-faire, or as little government interference with the economic system as possible. There were to be only a few

.

8

Salvatore’s Introduction to International Economics, 2nd Edition

Instructor’s Manual

exceptions to this policy of laissez-faire and free trade. One of these was the protection of industries important for national defense.

3.

Ricardo’s law of comparative advantage is superior to Smith’s theory of absolute advantage in that it showed that even if a nation is less efficient than or has an absolute disadvantage in the production of all commodities with respect to the other nations, there is still a basis for beneficial trade for all nations.

The gains from trade arise from the increased production of all commodities that arises when each country specializes in the production of and exports the commodities of its comparative advantage and imports the other commodities.

A nation that is less efficient than others will be able to export the commodities of its comparative advantage by having its wages and other costs sufficiently lower than in other nations so as to make the commodities of its comparative advantage cheaper in terms of the same currency with respect to the other nations.

4.

a. In case A, the United States has an absolute and a comparative 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. b. 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.

5.

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.

6.

a. The cost in terms of labor content of producing wheat is 1/4 in the United States 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.

7.

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.

8.

Ricardo’s explanation of the law of comparative is unacceptable because it is based on the labor theory of value, which is not an acceptable theory of value.

The explanation of the law of comparative advantage can be based on the opportunity cost doctrine, which is an acceptable theory of value.

LECTURE GUIDE 1.

In the first lecture of Chapter 3, I would cover Sections 1-5 and assign Review Question and Problems 1-3. Section 3 is the most difficult here and Section 5 is the most important, and so I would spend a bit more time covering them.

2.

In the second lecture, I would cover Sections 6 and 7. Section 6 presents the basic trade model, and is essential for the student to master it completely.

3.

In the third lecture, I would cover the rest of the chapter, starting with Case Study 3-1 and then going on to discuss the terms of trade. The last section on specialization, trade and deindustrialization is likely to be of great interest to the students and lead to a great deal of class discussion.

4.

I would make the Appendix optional for more advanced students in the class. Section A3.1 derives the supply curve and the demand curves for the commodity from the production frontier and the community indifference curves and shows how the equilibrium relative commodity price with trade is determined. Section A3.2 derives the offer curve of Nation 1 and Nation 2 and shows how the equilibrium-relative commodity price with trade and their terms of trade are determined at the intersection of their offer curves.

ANSWERS TO REVIEW QUESTIONS AND PROBLEMS 1.

a. Increasing opportunity costs arise because resources or factors of production are not homogeneous (i.e., all units of the same factor are not identical or of the same quality) and not used in the same fixed proportion or intensity in the production of all commodities.

This means that as the nation produces more of a commodity; it must utilize resources that become progressively less efficient or less suited for the production of that commodity. As a result, the nation must give up more and more of the second commodity to release just enough resources to produce each additional unit of the first commodity (i.e., it faces increasing costs). b. In the real world, the production frontiers of different nations will usually differ because of differences in factor endowments and technology.

2.

a. See Figure 3.1. 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.

a. See Figures 3.2a and 3.2b.

b. Nation 1 has a comparative advantage in X and Nation 2 in Y. c. If the relative commodity price line in autarky has equal slope in both nations. This is rare.

4.

a. See Figures 3.3a and 3.3 b. Points B and B’ are the production points in Nations 1 and 2, respectively, with specialization and trade and E and E’ are the consumption points.

b. Nation 1 gains by the amount by which community indifference curve III (point E) is above indifference curve I (point A). Nation 2 gains to the extent that community indifference curve III’ (point E’) is above indifference curve I’ (point A).

5.

a. The equilibrium-relative commodity price in isolation is the relative price that prevails in the nation without trade or in autarky. b. The equilibrium-relative commodity price in isolation for the commodity plotted along the horizontal axis is given by the (absolute) slope of the tangent of the production frontier and the community indifference curve at the point of production and consumption in the nation in isolation.

.

16

Salvatore’s Introduction to International Economics, 2nd Edition

Instructor’s Manual

c. The nation with the lower equilibrium relative commodity price in isolation or autarky has a comparative advantage in the commodity measured along the commodity axis and a comparative disadvantage in the commodity measured along the vertical axis.

6.

a. Nation 1 is better off at point E’ than at point A’ because point E’ is on higher community indifference curve III than at point A, which is on lower community indifference curve I. b. Nation 1 consumes less of commodity Y at point E’ (40Y) than at point A’ (60Y) because PY/PX is much higher at point E’ (PB’ =1) than at point A’ (PA’ =1/4, the inverse of PX/PY=4).

7.

a. The reason for incomplete specialization under increasing costs is that as each nation specializes in the production of the commodity of its comparative advantage, the relative commodity price in each nation moves toward each other (i.e., become less unequal) until they are identical in both nations. At that point, it does not pay for either nation to continue to expand the production of the commodity of its initial comparative advantage.

This occurs before either nation has completely specialized in production. b. Under constant costs, each nation specializes completely in production of the commodity of its comparative advantage (i.e., produces only that commodity). The reason is that since it pays for the nation to obtain some of the commodity of its comparative disadvantage from the other nation, then it pays for the nation to get all of the commodity of its comparative disadvantage from the other nation (i.e., to specialize completely in the production of the commodity of its comparative advantage).

8.

See Figure 3.5 (Please disregard Figure 3.4, which shows how to derive the demand and supply curve for commodity X for Nation 1 and Nation 2 that are used to show how the equilibrium relative commodity price is determined with trade – a topic that is covered in Appendix A3.1.

.

17

Salvatore’s Introduction to International Economics, 2nd Edition

Instructor’s Manual

Nations 1 and 2 have identical production frontiers (shown by a single curve) but different tastes (indifference curves). In isolation, Nation 1 produces and consumes at point A and Nation 2 at point A’. Since PA < PA’, Nation 1 has a comparative advantage in X and Nation 2 in Y. With trade, Nation 1 specializes in the production of X and produces at B, while Nation 2 specializes in Y and produces at B’ (which coincides with B). By exchanging BC = B’C’ of X for CE = C’E of Y with each other (see trade triangles BCE and B’C’E’), Nation 1 ends up consuming at E on indifference curve III (higher than indifference curve I at point A) and Nation 2 consumes at on indifference curve III’ (higher than indifference curve I’ at point A’).

9.

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 [(100-110)/110 = -0.09 =0.9%]. b. A deterioration in the terms of trade of the trade partner can be said to be unfavorable to the trade partner because the trade partner must pay a higher price for its imports in terms of its exports. c. 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.

10.

It is true that Mexico's wages are much lower than U.S. wages (they are about one fifth of the average wage in the United States), 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.

SAMPLE TEST QUESTIONS 1. A production frontier that is concave indicates that the nation incurs increasing opportunity costs in the production of: a. commodity X only b. commodity Y only c. both commodities d. neither commodity 2. The marginal rate of transformation (MRT) of X for Y refers to: a. the amount of Y that a nation must give up to produce each additional unit of X b. the opportunity cost of X c. the absolute slope of the production frontier at the point of production d. all of the above

LECTURE GUIDE 1.

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

2.

In the first lecture, I would cover sections 1-3. Section 3 is one of the most important sections in the book because it presents the H-O model. I would proceed slowly and carefully in explaining Figure 4.1 and compare it to the standard trade model of Figure 3.4.

3.

In the second lecture, I would cover sections 4 and 5. Section 4 on the factor-price equalization theorem and income distribution is a difficult section. Case Study 4-2 should be of great interest to the students and give rise to a great deal of class discussion.

4.

In third lecture, I would cover sections 6-7, paying a great deal of attention to section 7 on trade in differentiated products.

5.

In fourth lecture, I would cover the rest of the chapter.

ANSWERS TO REVIEW QUESTIONS AND PROBLEMS 1.

a. The Heckscher–Ohlin (H-0) theorem postulates that a nation will export those commodities whose production requires the intensive use of the nation’s relatively abundant and cheap factor and import the commodities whose production requires the intensive use of the nation’s relatively scarce and expensive factor. In short, the relatively labor-rich nation exports relatively labor-intensive commodities and imports the relatively capital-intensive commodities. b. Heckscher and Ohlin identify the relative difference in factor endowments among nations as the basic determinant of comparative advantage and international trade. c. The H-O Theory represents an extension of the standard trade model because it explains the basis for comparative advantage (classical economists, such as Ricardo had assumed it) and examines the effect of international trade on factor prices and income distribution (which classical economists had left unanswered).

See Figure 4.1.

3.

a. The factor–price equalization theorem postulates that international trade will bring about the equalization of the returns to homogeneous or identical factors across nations. b. The Stopler-Samuelson theorem postulates that free international trade reduces the real income of the nation’s relatively scarce factor and increases the real income of the nation’s relatively abundant factor. c. The specific-factors model postulates that the opening of trade (1) benefits the specific factor used in the production of the nation’s export commodity, (2) harms the specific factor used in the production of the nation’s import-competing industry, and (3) leads to an ambiguous effect (i.e., it may benefit or harm) the mobile factor. d. Trade acts as a substitute for the international mobility of factors of production in its effect on factor prices. With perfect mobility, labor would migrate from the low-wage nation to the high-wage nation until wages in the two nations are equalized. Similarly, capital would move from the low-interest to the high-interest nation until the rate of interest was equalized in the two nations.

4.

a. The Leontief paradox refers to the original Leontief’s finding that U.S. import substitutes were more K-intensive than U.S. exports. This was the opposite of what the HO theorem postulated. b. The Leontief paradox was resolved by including human capital into the calculations and excluding industries based on natural resources. Recent research using data on many sectors, for many countries, over many years, and considering that countries could specialize in a particular subset or group of commodities that were best suited to their specific factor endowments, provides strong support for the H-O theorem.

c. The Hecksher-Olhin theory remains the centerpiece of modern trade theory for explaining international trade today. To be sure, there are other forces (such as economies of scale, product differentiation, and technological differences across countries) that provide additional reasons and explanations for some international trade not explained by the basic H-O model. These other trade theories complement the basic H-O model in explaining the pattern of international trade in the world today.

5.

International 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 labor-saving 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.

6.

a. Economies of scale refer to the production situation where output grows proportionately more than the increase in inputs or factors of production. For example, output may more than double with a doubling of inputs. b. Even if two nations were identical in every respect, there is still a basis for mutually beneficial trade based on economies of scale. When each nation specializes in the production of one commodity, the combined total world output of both commodities will be greater than without specialization when economies of scale are present. With trade, each nation then shares in these gains. c. The new international economies of scale refers to the increase in productivity resulting from firms purchasing parts and components from nations where they are made cheaper and better, and by establishing production facilities abroad.

7.

a. Product differentiation refers to products that are similar, but not identical. Intraindustry trade refers to trade in differentiated products, as opposed to inter-industry trade in completely different products. b. Intra-industry trade arises in order to take advantage of important economies of scale in production. That is, with intra-industry trade each firm or plant in industrial countries can specialize in the production of only one, or at most a few, varieties and styles of the same product rather than many different varieties and styles of a product and achieve economies of scale. c. With few varieties and styles, more specialized and faster machinery can be developed for a continuous operation and a longer production run. The nation then imports other varieties and styles from other nations. Intra-industry trade benefits consumers because of the wider range of choices (i.e., the greater variety of differentiated products) available at the lower prices made possible by economies of scale in production.

8.

a. According to the technological gap model, a firm exports a new product until imitators in countries take away its market. In the meantime, the innovating firm will have introduced a new product or process.

.

24

Salvatore’s Introduction to International Economics, 2nd Edition

Instructor’s Manual

b. The criticism of the technological gap model are that it does not explain the size of technological gaps and does not explore the reason for technological gaps arising in the first place, or exactly how they are eliminated over time. c. The five stages of the product cycle model are: the introduction of the product, expansion of production for export, standardization and beginning of production abroad through imitation, foreign imitators underselling the nation in third markets, and foreigners underselling the innovating firms in their home market as well.

9.

See Figure 4.2.

10.

A nation with lower environmental standards can use the environment as a resource endowment or as a factor of production in attracting polluting firms from abroad and achieving a comparative advantage in the production of polluting goods and services.

This can lead to trade disputes with nations with more stringent environmental standards.

LECTURE GUIDE 1.

I would cover sections 1-4 in the first lecture. The most difficult part is Section 4 on 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 measuring the welfare effect of tariffs, I would explain these concepts very carefully.

2.

I would cover sections 5 and 6 in the second lecture. These are the most difficult sections in the chapter and also the most important.

3.

The theory of tariff structure is also difficult and important. I found that the best way to explain it is by using the simple example in the text on the suit with and without imported inputs. This section is likely to generate a great deal of discussion about the trade relations between developed and developing nations. If you do not plan to cover optional Chapter 8 on growth and development, you could spend a bit more time on this topic here, even though it will come up again in Chapter 6.

ANSWERS TO REVIEW QUESTIONS AND PROBLEMS 1.

a. See Figure 5.1. b. Consumption is 70X, production is 50X and imports are 20X. c. The consumption effect is –30X, the production effect is +30X, the trade effect is – 60X, and the revenue effect is $30 (see Figure 5.1).

2.

a. The consumer surplus is $250 without and $l22.50 with the tariff (see Figure 5.1). b. Of the increase in the revenue of producers with the tariff (as compared with their revenues under free trade), $22.50 represents the increase in production costs and another $22.50 represents the increase in rent or producer surplus (see Figure 5.1). c. The dollar value or the protection cost of the tariff is $45 (see Figure 5.1).

3.

The dollar value or the protection cost of the tariff is $45 (see Figure 5.2).

4.

The dollar value or the protection cost of the tariff is $45 (see Figure 5.3).

5.

The optimum tariff is the tariff that maximizes the net benefit resulting from the improvement in the nation’s terms of trade against the negative effect resulting from reduction in the volume of trade.

6.

a. When a nation imposes an optimum tariff, the trade partner’s welfare declines because of the lower volume of trade and the deterioration in its terms of trade. b. The trade partner is likely to retaliate and in the end both nations are likely to lose because of the reduction in the volume of trade.

.

34

Salvatore’s Introduction to International Economics, 2nd Edition

Instructor’s Manual

7.

Even when the trade partner does not retaliate when one nation imposes the optimum tariff, the gains of the tariff-imposing nation are less than the losses of the trade partner, so that the world as a whole is worse off than under free trade. It is in this sense that free trade maximizes world welfare.

8.

a. The nominal tariff is calculated on the market price of the product or service. The rate of effective protection, on the other hand, is calculated on the value added in the nation. It is equal to the value of the price of the commodity or service minus the value of the imported inputs used in the production of the commodity or service. b. The nominal tariff is important to consumers because it determines by how much the price of the imported commodity increases. The rate of effective protection is important for domestic producers because it determines the actual rate of protection provided by the tariff to domestic processing.

9.

a. Rates of effective protection in industrial nations are generally much higher than the corresponding nominal rates and increase with the degree of processing. b. The tariff structure of developed nations is of great concern for developing nations because it discourages manufacturing production in developing nations.

10.

If a nation reduces the nominal tariff on the importation of the raw materials required to produce a commodity but does not reduce the tariff on the importation of the final commodity produced with the imported raw material, then the effective tariff rates will increase relative to the nominal tariff rate on the commodity.

SAMPLE TEST QUESTIONS 1. Which of the following statements is incorrect? a. an ad valorem tariff is expressed as a percentage of the price of the traded commodity. b. a specific tariff is expressed as a fixed sum of the value of the traded commodity. c. export tariffs are prohibited by the U.S. Constitution d. the U.S. uses exclusively the specific tariff 2. A small nation is one: a. which does not affect world price by its trading b. which faces an infinitely elastic world supply curve for its import commodity c. whose consumers will pay a price that exceeds the world price by the amount of the tariff d. all of the above 3. If a small nation increases the tariff on its import commodity, its: a. consumption of the commodity increases b. production of the commodity decreases c. imports of the commodity increase d. none of the above

4. The increase in producer surplus when a small nation imposes a tariff is measured by the area: *a. to the left of the supply curve between the commodity price with and without the tariff b. under the supply curve between the quantities produced with and without the tariff c. under the demand curve between the commodity price with and without the tariff d. none of the above.

5. If a small nation increases the tariff on its import commodity: *a. the rent of domestic producers of the commodity increases b. the protection cost of the tariff decreases c. the deadweight loss decreases d. all of the above 6. The imposition of an optimum tariff by a small nation: a. improves its terms of trade b. reduces the volume of trade c. increases the nation's welfare d. none of the above 7. The optimum tariff for a small nation is: a. 100% b. 50% c. 0 d. It depends on the elasticity of demand and supply for the import commodity in the nation.

8. The imposition of an optimum tariff by a large nation: a. improves its terms of trade b. reduces the volume of trade c. increases the nation's welfare d. all of the above 9. The imposition of an optimum tariff by a large nation: a. improves the terms of trade of the trade partner b. reduces the volume of trade c. increases the trade partner’s welfare d. all of the above 10.

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 1-3 in lecture 1. I would pay particular attention to Figure 6-1, which examines the partial equilibrium effects of an import quota. I would also clearly explain the difference between a regular import quota and a voluntary export restraint.

3.

I would cover sections 4-6 in lecture 2. I would also clearly explain the meaning and importance of dumping and export subsidies, as well as the political economy of protectionism. The four case studies serve to highlight the theory and show the relevance of the theory in today's world.

ANSWERS TO REVIEW QUESTIONS AND PROBLEMS 1.

a. An import quota will increase the price of the product to domestic consumers, reduce the domestic consumption of the good, increase domestic production, and result in a protection or deadweight loss to the economy. b. The effects of an import quota are identical to those of an equivalent import tariff, except that with a quota the government does not collect a tariff revenue (unless it auctions off import quotas to the highest bidder). The import quota is also more restrictive than an equivalent import tariff because foreign producers cannot increase their exports by lowering their prices.

2.

By penciling in D”X in Figure 1, we can see that the effects of the import quota are: Px=$2.00 and consumption is 60X, of which 40X are produced domestically and 20X are imported; by auctioning off import licenses, the revenue effect would be $20.

3.

The effects of an export quota of 20X are identical to those of an import quota of 20X or a 100 percent import tariff on commodity X, except that the revenue effect is collected by the exporters, rather than by the domestic importers or their government.

4.

a. An international cartel is an organization of suppliers of a commodity located in different nations (or it is a group of governments) that agrees to restrict output and the exports of the commodity with the aim of maximizing or increasing the total profits of its members. Although domestic cartels are illegal in the United States and are restricted in Europe, the power of international cartels cannot easily be countered because they do not fall under the jurisdiction of any one nation. b. The most notorious of present-day international cartels is OPEC (Organization of Petroleum Exporting Countries), which, by restricting production and exports, succeeded in quadrupling the price of crude oil between 1973 and 1974. The economic power of OPEC declined during the 1980s and 1990s when many other nations (such as Russia, Mexico, Norway, the United Kingdom) encouraged by the sharp increase in prices started to extract and export petroleum.

5.

a. Dumping refers to the export of a commodity at below cost or at a lower price than the commodity is sold domestically. b. Dumping is classified as persistent, predatory, and sporadic. Persistent dumping, or international price discrimination, refers to the continuous sale of the commodity at a higher price in the domestic market than internationally. The incentive for persistent dumping is the higher profits it provides to domestic producers.

Predatory dumping is the temporary sale of a commodity at below cost or at a lower price abroad than at home in order to drive foreign producers out of business, after which prices are raised to maximize profits. Sporadic dumping is the occasional sale of a commodity at below cost or at a lower price abroad than domestically in order to unload an unforeseen and temporary surplus of the commodity without having to reduce domestic prices. c. Dumping usually leads to trade restrictions as nations try to protect domestic producers from “unfair” foreign competition, even when the dumping is persistent and sporadic.

6.

a. The infant-industry argument postulates that temporary protection may be justified in order to allow a developing nation to develop an industry in which it has a potential comparative advantage. Temporary trade protection is then justified to establish and protect the domestic industry during its “infancy” until it can grow and meet foreign competition. For this argument to be valid, however, protection must be temporary and the return in the grown-up industry must be sufficiently high to also offset the higher prices paid by domestic consumers of the commodity during the period of infancy. b. The infant-industry argument must be qualified in several important ways to be acceptable. First, this argument is more justified for developing nations (where capital markets may not function properly) than for industrial nations. Second, it is usually difficult to identify which industry or potential industry qualifies for this treatment, and experience has shown that protection, once given, is difficult to remove. Third, and most important, what trade protection (say in the form of an import tariff) can do, an equivalent production subsidy to the infant industry can do better.

7.

a. Outsourcing refers to a firm’s purchase of parts and components abroad, while offshoring to a firm producing parts and components in its own plant abroad. Both are undertaken by firms in order to remain internationally competitive. b. Outsourcing and offshoring are by give rise to fear of globalization or the transfer of a large number of high-skill U.S. jobs abroad. While this has not occurred on a large scale in the past, the fear is that this could take place now and is made possible because of the revolution in telecommunications.

8.

a. According to strategic industrial trade policy a nation can create a comparative advantage (through temporary trade protection, subsidies, tax benefits, and cooperative government–industry programs) in a high-technology field deemed crucial to future growth in the nation. b. There are also serious difficulties in carrying strategic industrial and trade policies.

First, it is extremely difficult to pick winners (i.e., choose the industries that will contribute significantly to growth in the future). Second, if most leading nations undertake strategic trade policies at the same time, their efforts are largely neutralized.

Third, when a country does achieve substantial success with a strategic trade policy, this comes at the expense of other countries (i.e., it is a beggar-thy-neighbor policy), which are, therefore, 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.

9.

a. The main provisions of the Uruguay Round were the reduction of average tariffs on industrial goods from 4.7 percent to 3 percent, for quotas to be replaced by tariffs, and for antidumping and safeguards to be tightened. The agreement also called for the reduction in agricultural export subsidies and industrial subsidies, and for the protection of intellectual property. b. It has been estimated that the implementation of the Uruguay Round increased world welfare by $73 billion, of which $58.3 billion of the gains went to developed countries and 19.2 billion to developing countries.

a. The major trade problems facing the world today are (1) the serious trade disputes among the United States, the European Union, and Japan; (2) the high trade protectionism, especially in agriculture and textiles, which are of great importance to developing countries, and the abuse antidumping and safeguards; (3) the breaking up of the world into a few major trading blocks, and a serious anti-globalization movement that has come into existence. b. The Doha Round is needed to take up all of the above problems, but its completion has been stalled primarily because of disagreements on agricultural protectionism between developing and developed countries.

SAMPLE TEST QUESTIONS 1. An import quota: a. increases the domestic price of the imported commodity b. reduces domestic consumption c. increases domestic production d. all of the above 2.

LECTURE GUIDE 1.

This is not a core chapter and I would skip it, except for sections 7-4 to 7-8 dealing with the European Union (EU), The European Free Trade Association, the North American Free Trade Agreement (NAFTA), and the Southern Common Market (Mercosur).

2.

I would take two classes to cover the material. Case Studies 7-1 to 7-4 can be used for a very stimulating class discussion.

ANSWERS TO REVIEW QUESTIONS AND 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 tariff-inclusive 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. The formation by Nation A of a customs union with Nation B leads to trade creation only because Nation A replaces the 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 tariffinclusive 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 tariffinclusive price of $9. b. The formation by Nation A of a customs union with Nation B leads not only to trade creation but also to trade diversion because it replaces lower-cost 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.

a. See Figure 7.1.

b. 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 7-1 in the text, however, the sum of the areas of the two triangles (measuring gains) is here 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.

6.

A customs union that leads to both trade creation and trade diversion is more likely to lead to a net positive welfare gain of the nation joining the union (1) the smaller is the relative inefficiency of the union member in relation to the non-union member and (2) the higher is the level of the tariff imposed by the customs union on the non-union member.

7.

The dynamic benefits resulting from the formation of a customs union are (1) increased competition, (2) economies of scale, (3) stimulus to investment, and (4) better utilization of economic resources. These are likely to be much more significant than the static benefits.

8.

See Figure 7.2. The formation of the customs union has no effect.

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

10.

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.

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

ANSWERS TO REVIEW QUESTIONS AND PROBLEMS 1.

a. International trade could retard development by: (1) keeping the nation in primary production; (2) leading the nation to adopt excessive capital-intensive production techniques; (3) increasing the propensity to consume, thus reducing the nation's savings rate; (4) leading to foreign exploitation of natural resources. b. Each of the above criticisms that international trade can retard development can be countered as follows: (1) As the availability of capital and technology increases, the nation can begin to export manufactured goods; (2) through appropriate taxes and subsidies the nation can avoid the use of excessive capital-intensive production techniques; (3) increased taxation can increase the rate of public savings; (4) taxation and regulation can reduce or eliminate foreign exploitation.

5.

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.

6.

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 is better off in 2003 than it was in 1980 because of its greater ability to import goods and services.

7.

a. Immiserizing growth can take place if the supply curve of the factor used in the nation’s export commodity increases so much as to cause such a large deterioration in the nation’s terms of trade (as the nation tries to export more of its commodity) that the nation reaches a lower indifference curve after growth than before growth. b. Immiserizing growth occurred rarely in the real world because the deterioration in the nations terms of trade is more than neutralized by increase in the volume of the nation’s exports (so that the nation’s terms of trade improve).

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 and the World Bank Sponsored New Millennium Goals (NMGs) in 2000. b. 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.

10.

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.

SAMPLE TEST QUESTIONS 1. If only the supply of labor increases in a nation, the nation’s production frontier shifts a. only along the axis measuring the L-intensive commodity b. only along the axis measuring the K-intensive commodity c. more along the axis measuring the L-intensive commodity d. in the same proportion along both axes 2. According to traditional trade theory, a developing nation should export the commodity a. of its comparative advantage b. that it can produce relatively more efficiently c. intensive in the nation's relatively abundant factor d. all of the above 3. International trade was an engine of growth for the a. regions of recent settlements during the 19th century b. regions of recent settlements during the 20th century c. developed nations during the 19th century d. developed nations during the 20th century 4. Trade cannot be an engine of growth for today's developing nations because a. the income elasticity for many of their exports is less than 1 b. the development of synthetic substitutes c. technical advances reduced the raw-material content of many products d. all of the above

5. If the price of a nation's exports and imports both rise, the nation's commodity terms of trade a. improve b. deteriorate c. remain unchanged d. any of the above 6. The nation's commodity terms of trade times the quantity index of its export sector gives the nation's a. income terms of trade b. commodity terms of trade c. factoral terms of trade d. all of the above 7. When a nation's commodity terms of trade deteriorate and its income terms of trade improve, the nation's welfare a. falls b. rises c. remains unchanged d. any of the above 8.

9. Developing nations often experience wildly fluctuating export prices for their primary products because of a. inelastic and stable demand and supply b. elastic and unstable demand and supply c. inelastic and unstable demand and supply d. elastic and stable demand and supply 10. Empirical studies have found that, in general, the export instability faced by developing nations was: a. not very large and did not seriously interfere with development b. very large and seriously interfered with development c. very large but did not seriously interfere with development d. not very large but seriously interfered with development 11. The policy of import substitution was most vigorously followed by a. large developing nations during the 1980s b. large developing nations during the 1960s c. small developing nations during the 1970s d. small developing nations during the 1960s

12. What is the advantage of a policy of import substitution? a. setting up an industry to replace imports minimizes risk of failure because the market for the product already exists in the nation as evidenced by the nation's imports of the commodity b. it is easier for developing nations to protect their domestic market against foreign competition than to force developed nations to lower their trade barriers against their manufactured exports c. foreign firms are induced to establish tariff factories to overcome the tariff wall of developing nations d. all of the above.

13. Which are is not an advantage of export-oriented industrialization? a. it overcomes the smallness of the domestic market and allows developing nations to take advantage of economies of scale b. domestic industries grow accustomed to protection and have an incentive to become more efficient c. production of manufactured goods for export requires and stimulates efficiency throughout the economy d. the expansion of manufactured exports is not limited by the size of the domestic market.

14. Those nations that liberalized trade during the past decade a. grew faster than those that did not b. grew more slowly than those that did not c. grew at about the same rate as those that did not d. any of the above 15. Which of the following is not part of the demand for a NIEO? a. the establishment of international commodity agreements b. preferential access for the manufactured exports of developed nations c. removal of the agricultural trade barriers in developed nations d. increasing the yearly flow of foreign aid to developing nations

LECTURE GUIDE This is not a core chapter and I would skip it except for sections 9.7 to 9.9 on multinational corporations and section 9.10 on immigration. Otherwise, I would present two sections in each of three classes.

ANSWERS TO REVIEW QUESTIONS AND PROBLEMS 1.

International trade can be regarded as a substitute for the movements of productive resources in the sense that a relatively capital-abundant and labor-scarce country, such as the United States, could either export capital-intensive commodities or export capital itself, and either import labor-intensive products or allow the immigration of workers from countries with plentiful labor supplies. The opposite is the case for a relatively capital-poor and labor-abundant developing country.

2.

a. Portfolio investments, such as the purchase of bonds, are purely financial assets and take place primarily through banks and investment funds. b. Direct investments are real investments in factories, capital goods, land, and inventories where both capital and management are involved and the investor retains control over use of the invested capital. International direct investments are usually undertaken by multinational corporations.

3.

a. The basic motives for international portfolio investments are yield maximization and risk diversification. Risk diversification is also necessary to explain two-way capital flows. b. Direct foreign investments are also undertaken for yield maximization and risk diversification but require additional explanations. These are (1) to exploit abroad some unique production knowledge or managerial skill (horizontal integration), (2) to gain control over a foreign source of a needed raw material or a foreign marketing outlet (vertical integration), (3) to avoid import tariffs and other trade restrictions and/or to take advantage of production subsidies, (4) to enter a foreign market to share in its profits, (5) to acquire a foreign firm in order to avoid future competition, or (6) because of unique ability to obtain financing.

4.

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 cannot 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.

5.

a. The share of national income going to labor decreases while that going to capital increases in the investing nation.

.

61

Salvatore’s Introduction to International Economics, 2nd Edition

Instructor’s Manual

b. The increase in the share of national income going to capital increases more than the fall in the relative share going to labor. Therefore, the investing nation as a whole benefits (i.e., it average national income increases). The nation receiving the foreign capital will also experience a net increase in average national income.

6.

Some of the alleged problems created by multinational corporations in the home country are the export of domestic jobs, erosion of the home nation’s technological advantage, avoidance of domestic taxes through transfer pricing, and reduced government control over the domestic economy.

7.

a. Host countries complain multinational corporations operating in the nation lead to a loss of sovereignty and domestic research activity, tax avoidance, the utilization of inappropriate technology, and most benefits flowing to the home nation. b. Host countries try to minimize the alleged harmful effects of multinationals operating in the country by and increase the possible benefits in a variety of ways. Some nations, such as Canada, impose higher taxes on foreign affiliates with less than 25 percent Canadian interest. Other nations, such as India, specify the sectors in which direct foreign investments are allowed and sets rules to regulate their operation. Some developing nations allow only joint ventures (i.e., local equity participation) and set rules for the transfer of technology and the training of domestic labor, impose limits on the use of imported inputs and the remission of profits, set environmental regulations, and so on.

8.

The data to update Table 9.6 are found in the World Investment Report published yearly by the United Nations for the most recent year.

9.

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.

10.

a. International labor migration can occur for economic and non-economic reasons.

When the decision to migrate is economic, it can be evaluated in terms of costs and benefits just as any other investment in human and physical capital. b. International migration tends to increases real wages in the nation of emigration and to reduce them in the nation of immigration, at least in the short run. This is why U.S. labor generally opposes immigration. Over time, however, migration is likely to benefit both the nation of emigration and the nation of immigration because of the better utilization of world labor.

In the first lecture, I would cover sections 1-4. 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 3. I would also assign problems 1-8.

2.

In the second lecture, I would go over problems 1-8 and cover sections 5-7 and stress the meaning and measurement of balance of payments deficits and surpluses.

3.

In the third lecture, I would cover sections 8 and 9. Case studies 10-2 to 10-5 are likely to provide interesting class discussion.

ANSWERS TO REVIEW QUESTIONS AND PROBLEMS 1.

a. The U.S. debits its current account by $500 (for the merchandise imports) and credits capital by the same amount (for the increase in foreign assets in the U.S.). b. The U.S. credits capital by $500 (the drawing down of its bank balances in London, a capital inflow) and debits capital by an equal amount (to balance the capital credit that the U.S. importer received when the U.K. exporter accepted to be paid in three months). c. The U.S. is left with a $500 debit in its current account and a net credit balance of $500 in its capital 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. b. 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.

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

5.

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

6.

7.

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

8.

a. The U.S. credits its capital 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.

10.

a. The benefit that the United States received from becoming a net debtor nation is that the United States utilized foreign capital to finance some of its investments (thus allowing it to grow faster) and some of its public consumption (public debt) without the need to increase interest rates, which would have slowed growth. b. The risk that the United States faces in becoming a net debtor nation is that foreigners may suddenly stop investing in the United States and financing the public debt. That would cause a financial crisis in the United States and a sharp increase in interest rates.

LECTURE GUIDE 1.

.

This is another important and challenging core chapter. I would cover 2 sections in each of four classes.

77

Salvatore’s Introduction to International Economics, 2nd Edition

Instructor’s Manual

2.

Section 2 is a crucial section because it provides an overview of exchange rate determination.

3.

Section 3 briefly examines the elasticity or trade approach to exchange rate determination.

This is a simple introduction to what will be examined in detail in Chapter 13.

4.

Section 4 on the purchasing power parity (PPP) theory is not too difficult and students will find Case Study 2 particularly interesting.

5.

Section 5 and section 6 examine, respectively, how exchange rates are determined according to the monetary and the asset or portfolio model. These are, of course, simplified version of the models that are fully developed in Chapter 15 of my more advanced International Economics text (9th ed., Wiley, 2007; 10th ed., Wiley, 2011).

6.

Section 7 on exchange rate overshooting can be challenging for students, especially the reason for the overshooting.

7.

In covering Section 8 on empirical testing of the monetary and asset market or portfolio balance models and exchange rate forecasting it is important to clearly point out to students that even though empirical tests do lens much support the theories presented in the chapter, this does not mean that the theories are wrong or useless.

ANSWERS TO REVIEW QUESTIONS AND PROBLEMS 1.

If economic growth increased in the EMU but not in the United States, the EMU would demand more U.S. exports and supply more euros to the United States, and this would lead to a reduction in the dollar/euro exchange rate (appreciation of the dollar).

2.

If the price level increased in the United States less than in the EMU, the United States would find imports from the EMU more expensive while the EMU would find U.S. exports cheaper. This will reduce the U.S. demand for euros (the U.S. demand curve for euros shifts down and to the left) but increase the U.S. supply of euros (the U.S. supply curve for euros shifts down and to the right). Both of these effects would lead to a reduction in the dollar/euro exchange rate (dollar appreciation).

3.

If the interest rate increased in the United States but remained unchanged in the European Monetary Union (EMU), both the United States and the EMU would demand fewer euros. This would reduce the U.S. demand and increase the U.S. supply of euros and lead to a decline in the dollar/euro exchange rate (the dollar to appreciate).

4.

If the expectation suddenly arises that the dollar will appreciate, U.S. and EMU investors would buy dollars with euros, now that the dollar is cheap in the anticipation of selling dollars for euros (and thus earn a profit) after the dollar appreciates. This would reduce the U.S. demand and increase the U.S. supply of euros, both or which cause a decrease in the dollar/euro exchange rate (an appreciation of the dollar).

.

78

Salvatore’s Introduction to International Economics, 2nd Edition

Instructor’s Manual

5.

If growth, inflation, and interest rates increase in the United States but not in the European Monetary Union, the effect on the dollar/euro exchange rate depends on the net effect of these changes on the U.S. demand and supply curve.

6.

a. The absolute purchasing-power parity theory postulates that the equilibrium exchange rate between two currencies is equal to the ratio of the price levels in the two nations, so that a given commodity would have the same price in the two countries when expressed in terms of the same currency (the law of one price). The absolute PPP theory would hold only if there were no transportation costs, tariffs or other obstructions to the free flow of trade; if all commodities were traded internationally; and if no structural changes (such as wars) took place in the United States and the EMU. Since these assumptions do not hold in the real world, the absolute version of the PPP cannot be taken seriously. Whenever the purchasing-power parity theory is used, it is usually in its relative formulation. b. The relative purchasing-power parity theory postulates that the percentage change in the exchange rate is equal to the difference in the percentage change in the two countries' general price levels (as long as there are no changes in transportation costs, obstructions to trade, ratio of traded to nontraded goods, and in the structure of the two economies). c. Empirical tests indicate that relative purchasing power-parity (PPP) holds reasonably well only in the long run.

7.

a. The rate of inflation in the United Kingdom from 1973 to 2003 was:

On the other hand, the rate of inflation in the United States from 1973 to 2003 was:

Thus, the inflation rate in the United Kingdom minus the inflation rate in the United States from 1973 to 2003 was: 154.0% - 122.5 = 31.5% From 1973 to 2003, the British pound depreciated with respect to the U.S. dollar from £0.4304 to the dollar in 1973 and £0.5975 per dollar in 2003 or by 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 problem, so that students would get as to get the same answer as given above. b. The relative PPP theory did hold because the rate of inflation was higher in the United Kingdom than in the United States by almost the exact percentage by which the pound depreciated with respect to the dollar from 1973 to 2003.

8.

.

a. According to the monetary model, an increase in the nation’s money supply leads to a proportionate increase in prices and depreciation of the nation’s currency in the long run, as postulated by the PPP theory. This means that the nominal and real exchange rates of the nation’s currency should move together by the same percentage over time.

79

Salvatore’s Introduction to International Economics, 2nd Edition

Instructor’s Manual

b. Empirical tests do not lend much support to the monetary model of exchange rates. One reason for this is that the monetary approach does not include all of the factors that affect the exchange rate.

9.

a. The asset or portfolio approach postulates that an increase in a nation's money supply leads to an immediate decline in the interest rate in the nation and to a shift from domestic bonds to the domestic currency and to foreign bonds. The shift from domestic to foreign bonds causes an immediate depreciation of the home currency as individuals and firms exchange domestic for foreign currency in order to purchase more foreign bonds. b. The asset or portfolio approach of exchange rates differs from the monetary model by postulating that the exchange rate is determined in the process of equilibrating or balancing the stock or total demand and supply of financial assets (of which money is only one, as in the monetary approach) in each country. It also brings trade explicitly into the analysis. c. Although theoretically superior to the monetary approach, empirical tests do not lend much support to the asset or portfolio approach of exchange rates either.

10.

The asset or portfolio approach postulates that an increase in a nation's money supply leads to an immediate decline in the interest rate and shift from domestic to foreign bonds. This causes an immediate depreciation of the nation’s currency. Over time, this leads to a trade surplus and an appreciation of the domestic currency, which neutralizes part of its original depreciation, thus explaining the exchange rate overshooting often observed in the real world.

LECTURE GUIDE 1.

This is an important and challenging core chapter.

2.

I would cover sections 1-3 in the first lecture, paying particular attention to Figures 13.1 and 13.2. I would explain the J-curve and the pass-through effect with Case Study 2 on the effective exchange rate of the dollar and the U.S. current account balance.

3.

In the second lecture I would cover Sections 4-6. Section 4 deals with the gold standard and it is important because other fixed exchange rate systems operate (or are supposed to operate) in a similar way. Section 5 is a review of Keynesian economics from principles of economics, but my experience is that students need this review very much. Section 6 deals with open economies and is, of course, one of the major aims of the chapter.

4.

In the third lecture, I would cover the remainder of the chapter. Section 7 examines foreign repercussions without presenting foreign trade multipliers with foreign repercussions because they are very complex and unnecessary for understanding the importance foreign repercussions. Section 8 deals with the absorption approach and is very important because it provides a synthesis of the automatic price and income adjustment mechanisms. Section 9 then provides an overview of automatic adjustments under flexible and fixed exchange rates, including their disadvantages.

ANSWERS TO REVIEW QUESTIONS AND PROBLEMS 1.

a. A depreciation is inflationary because the country needs more of its currency to purchase each unit of the foreign currency. Therefore, even if the foreign price of a foreign good remains unchanged, it will cost more for the nation to purchase in terms of the domestic currency. b. If the nation’s demand and supply curve of the foreign currency are inelastic, a depreciation will not be feasible to correct a deficit in the nation’s balance of payments because the depreciation will be very inflationary (and thus create an inflation problem for the nation, which may worse than its balance-of-payments deficit problem).

2.

Although the U.S. trade deficit with Japan has not been reduced despite the fact that the U.S. dollar depreciated sharply with respect to the Japanese yen during the past 10-15 years, this does not mean that the trade or elasticity approach to balance-of-payments adjustment does not work. The reason is that a nation’s balance of payments depends on many other factors, such as the rate of growth and the savings rate of a nation in relation to its trade partner’s. The much higher rate of growth and lower savings rate of the United States than Japan led to U.S. imports from Japan rising much more rapidly that Japanese imports from the United States. Without the sharp depreciation of the dollar with respect to the yen, the U.S. trade deficit with Japan would have been even greater.

a. A depreciation of a nation’s currency from a position of full employment will lead to excess demand in the nation (as the nation tries to produce more exports and import substitutes) and inflation unless domestic absorption (consumption and investments) are somehow reduced. b. Domestic absorption is reduced if the depreciation of the nation’s currency (1) redistributes income from wages to profits (since profits earners usually have a higher marginal propensity to save than wage earners), (2) increases in domestic prices and reduces wealth, and hence expenditures in the nation, and (3) leads to inflation which pushes people into higher tax brackets and results in reduced consumption.

LECTURE GUIDE 1.

This is one of the most important and challenging chapters.

2.

In the first class, I would cover Sections 14.1 to 14.3. The objective of nations in Section 14.2 is likely to generate a great deal of class discussion. What needs to be pointed out is that in a course of international economics, we can only deal explicitly only with the objectives of full employment with price stability and equilibrium in the balance of payments.

3.

What needs also to be pointed out is that, at least initially, we will deal only demand-pull inflation, where prices being to rise only after the economy has reached full employment.

This type of inflation arises from excess aggregate demand and, as such, it is the opposite of recession of unemployment. This is the type of inflation which advanced economies are more likely to face today than in the 1970s and 1980s.

4.

Finally, students need to clearly understand why nations have generally been unwilling to change their exchange rate even when faced with large and persistent (fundamental) balance of payments disequilibrium, so that they are then forced to try to achieve internal and external balance only with fiscal and monetary policies.

5.

In the second class, I would cover Sections 14.4 to 14.6. These deal with the effectiveness of monetary and fiscal policies under fixed exchange rates. It is crucial here to explain well why monetary policy is ineffective while fiscal policy is effective. This will reconnect the student with the material covered in Chapter 13.

6.

The most difficult part in the explanation of why fiscal policies are relatively more effective in correcting the internal imbalance while monetary policy is relatively more effective in correcting the external imbalance.

7.

In the third class, I would cover the remainder of the chapter dealing with correcting unemployment with inflation, the policy mix in the real world, and direct controls. These topics as well as the case studies in these sections are also likely to generate a great deal of class discussion.

ANSWERS TO REVIEW QUESTIONS AND PROBLEMS 1.

Nations need policies to adjust a balance-of-payments disequilibrium when they are large and persistent. If they do not, they will run out of international reserves under a fixed exchange rate system or will face a continuously depreciating currency, which is inflationary.

2.

a. The most important economic goals or objectives of nations are (1) internal balance, (2) external balance, (3) a reasonable rate of growth, (4) an equitable distribution of income, and (5) adequate protection of the environment.

.

94

Salvatore’s Introduction to International Economics, 2nd Edition

Instructor’s Manual

b. In a course in international economics, we deal primarily with the objectives of internal and external balance. On the two, internal balance is clearly more important to the citizens and, thus to the government, of the nation.

3.

a. To achieve internal balance the nation can use expenditure-changing policies (i.e., fiscal and monetary policy) while to achieve external balance, the nation can use expenditure-switching policies (devaluation or revaluation). b. Expenditure-changing policies operate to increase production and income in the nation to correct recession and unemployment and to reduce production and income to correct inflation. On the other hand, expenditure-switching policies increase the demand for nation’s exports and reduce the nation’s demand for imports to correct a balance of payments deficit and work in the opposite direction to correct a surplus.

4.

a. When the nation faces a recession and a balance of payments deficit and the nation is not willing to change the exchange rate, the nation should use expansionary fiscal policy to correct the internal imbalance and contractionary monetary policy to correct the balance of payments deficit. b. By increasing government expenditures and/or reducing taxes, expansionary fiscal policy increases domestic production and income, and cures the recession. Contractionary monetary policy reduces the money supply and increases the rate of interest in the nation.

This attracts foreign capital and improves the nation’s capital account. The increase in the interest rate also reduces domestic investments and income, and thus imports, so that the current account of the nation also improves. c. Although there seems to be a conflict between the expansionary fiscal policy and the contractionary monetary policy, they will still work to correct the internal and external imbalances. The reason is that fiscal policy is relatively more effective in dealing with the internal imbalance while monetary policy is relatively more efficient in correcting the external imbalance. Because of this, these two opposing policies do not neutralize each other, but leave a net effect on the target toward which the policy is directed.

5.

a. The “assignment rule” refers to directing a policy toward the objective toward which it is relatively more efficient. This is internal balance for fiscal policy and external balance for monetary policy. b. It is important to follow the assignment rule because, if is not followed, the policies will increase rather than reduce or eliminate the internal and external imbalances.

6.

Monetary is policy completely ineffective to achieve internal balance with perfect international capital mobility under fixed exchange rates because trying to cure a recession using monetary policy would lead to a balance of payments deficit, which the nation must cover out of its international reserves. Otherwise, the currency depreciates and the nation would have to abandon the fixed exchange rate system. But intervening in the foreign exchange market to purchase the domestic currency with its international reserves, however, reduces the nation’s money supply and eliminates all of the increase in the money supply of the expansionary monetary policy.

.

95

Salvatore’s Introduction to International Economics, 2nd Edition

Instructor’s Manual

7.

a. If the nation operates with flexible exchange rates and international capital mobility is not perfect, then the nation should use expansionary monetary policy to correct the recession. Fiscal policy will not be effective in the short run because an expansionary fiscal policy will increase production and income but it will also increase the interest rate in the nation and lead to a capital inflow, which causes an appreciation of the nation’s currency thus dampening the increase in production and income from the expansionary fiscal policy. b. With perfect international capital mobility, monetary policy will become all-powerful, while fiscal policy becomes completely ineffective in the short run.

8.

a. To correct a recession and a balance of payments deficit when the nation also faces inflation, the nation could use fiscal policy to correct the recession, contractionary monetary policy to correct inflation, and leave to flexible exchange rate the function of correcting the deficit in the nation’s balance of payments and keeping it in equilibrium. b. If the nation operates with a fixed exchange rate, the nation will have to devalue its currency to correct the balance of payments deficit. One (much less preferable) alternative would be to use price and wage controls.

9.

The difficulties in using policies is that it may take time to decide on them and then for them to operate or bring about results, by the time this occurs, the problem may have been resolved, so that the policy will actually create instability. Then, here is the possibility of adopting the wrong policies. Automatic adjustments do not have these problems, but they have shortcomings of their own. Thus, the relative advantages and disadvantages of automatic adjustments relative to adjustment policies must be evaluated, and these may depend on the particular type of country and situation in which the country finds itself.

10.

a. The advantage of direct controls is that they operate on the balance of payments item that is creating a problem. Alternative policies may also not be readily available. b. The disadvantage of direct controls is that they interfere with the efficient operation of markets and usually result in great inefficiency.

SAMPLE TEST QUESTIONS 1. The most important economic objective of advanced nations is: a. external balance b. internal balance c. a reasonable rate of growth d. an equitable distribution of income 2. In order to achieve internal and external balance simultaneously, a nation must usually use: a. one policy b. two policies c. three policies d. cannot say

LECTURE GUIDE 1.

This chapter brings together, for the most part, material scattered throughout previous chapters on the question of fixed versus flexible exchange rates. But it also examines the European Monetary System, currency board arrangements, dollarization, and international macroeconomic cooperation. It is an important chapter but if time is short , I would omit it, except for sections 15.7 to 15.10.

2.

If I were to cover the entire chapter, I would cover sections 1 to 4 in the first lecture, section 5 to 7 in the second lecture, and sections 8-10 in the third lecture.

ANSWERS TO REVIEW QUESTIONS AND PROBLEMS 1.

a. The advantages of a fixed exchange rate system are lower uncertainty, the belief that speculation is more likely to be stabilizing, and being less inflationary. Advocates of flexible exchange rates disagree. They point out that destabilizing speculation is less likely to occur when exchange rates adjust continuously than when they are prevented from doing so until a large discrete adjustment can no longer be avoided. They do admit, however, that flexible exchange rates are more likely to be inflationary and to lead to greater exchange rate volatility. b. Whether flexible or fixed exchange rates are better depends, to a large extent, on the nation involved and the conditions under which it operates. In general, a fixed exchange rate is preferable if disturbances are predominantly monetary (such as inflation), while a flexible exchange rate is preferable if disturbances are predominantly real (such as a change in technology) and originate abroad.

3.

a. An optimum currency area involves permanently fixed exchange rates as well as common monetary and fiscal policies among its members. There are no such implications for countries which are connected only by fixed exchange rates. b. The main advantages of an optimum currency area for a nation are greater price stability and thus stimulating the specialization in production and the flow of trade and investments among member nations. An optimum currency area also encourages producers to view the entire area as a single market and to benefit from greater economies of scale in production. c. The requirements for a well-functioning optimum currency area are a great deal of labor mobility, structural similarities, and willingness to closely coordinate their fiscal and other policies.

4.

The benefits on EMU countries from the adoption of the euro are: (1) elimination of the need to exchange currencies among euro-area members; (2) elimination of exchange rate volatility among the currencies of participating countries; (3) more rapid economic and financial integration of participating nations; (4) participation in determining EMU’s monetary policy; (5) greater economic and budgetary discipline; (6) seignorage from the use of the euro; (7) reduced cost of borrowing in international financial markets; and (8) increased economic and political importance in international affairs. The most serious problem created by the adoption of the euro for the participating countries arises from being unable to conduct an independent monetary policy.

5.

a. Under a fixed exchange rate system, the nation fixes the exchange rate and intervenes in the foreign exchange market to keep the exchange rate within narrowly defined limits. b. Under a currency board arrangement, the nation rigidly fixes the exchange rate and its central bank loses its ability of conducting an independent monetary policy by allowing the nation’s supply to increase or decrease only in response to balance-of-payments surpluses or deficits. c. With dollarization the nation adopts another nation’s currency as its legal tender.

6.

Under a crawling peg system, nations change their exchange rates by small amounts at frequent specified intervals. This avoids destabilizing speculation that often arises under an adjustable peg system where nations change their exchange rates reluctantly and only when forced by market conditions, thus generating destabilizing speculation.

7.

a. Under a managed exchange rate system or dirty floating, monetary authorities intervene in foreign exchange markets to smooth out excessive exchange rate volatility. b. The policy of leaning against the wind operates by a nation’s monetary authorities selling the foreign currency on the foreign exchange market to reduce the depreciation of the national currency and purchasing the foreign currency to reduce the appreciation of the national currency. c. The major advantage of a managed floating exchange rate system with respect to a freely floating exchange rate is that it limits exchange rate volatility. The main advantage with respect to a fixed exchange rate system is that it corrects a balance of payments disequilibrium by exchange rate changes rather than requiring changes in all internal prices in the nation.

8.

A flexible exchange rate does 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 more expensive, 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 and lead to capital outflows. Unless the trade partner is able to continuously sterilize its 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.

9.

In a non-cooperative equilibrium, each nation is likely to follow a loose fiscal policy but a tight monetary policy in order to keep its interest rates up (thereby attracting foreign capital and keeping the international value of its currency high and 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 longterm 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 stimulate long-run growth.

10.

a. International macroeconomic policy coordination among the leading industrial countries is useful because it allows the adoption of some beneficial policies that a nation would not undertake alone. For example, with a worldwide recession, each nation may hesitate to stimulate its economy to avoid a deterioration of its trade balance. Through a coordinated simultaneous expansion of all nations, however, output and employment can increase in all nations without any of them suffering deterioration in its trade balance. 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.

SAMPLE TEST QUESTIONS 1. An alleged advantage of flexible over fixed exchange rates is: a. market efficiency b. stabilizing speculation c. price discipline d. all of the above 2. Flexible exchange rates: a. enhance the effectiveness of fiscal policy b. reduce the effectiveness of fiscal policy c. enhance the effectiveness of monetary policy d. reduce the effectiveness of monetary policy

The formation of an optimum currency area is more likely to be beneficial: a. the smaller is the mobility of resource among the various nations of the optimum currency area b. the smaller are the structural similarities of member nations c. the more willing are member nations to closely coordinate their economic policies d. all of the above 8. The European Monetary System is or resembles a: a. fixed exchange rate system b. a managed exchange rate system c. a crawling peg system d. a freely flexible exchange rate system 9.

a. 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. b. 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.

a. 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 IMF in any one year. b. Today, the nation would pay 25 percent of its quota in SDRs or in currencies of other members selected by the IMF, and the rest in their own currency. Under the new rules in operation today, the nation can borrow a maximum of up to 50 percent of its quota in any one year plus additional amounts under the various programs to facilitate borrowing that the IMF has put in place over the years.

3.

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.

4.

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.

5.

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.

6.

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.

7.

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 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 increasing the amount that it could borrow in order to provide financial assistance to those nations that do face a serious financial crisis.

8.

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. 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.

9.

a. All the economic crises in emerging market economies during the past decade 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 portfolios 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 six emerging market crises: Mexico in 1994-5, South-East Asia in 1997-1999, Russia in summer 1998, Brazil in 1999, Turkey in 2001, and Argentina in 2002. b. Proposed solutions to avoid future crises in emerging market economies include: (1) Avoid over borrowing of short-term funds (2) increased transparency in financial relations, (3) strengthening emerging markets’ banking and financial system, and (4) greater private sector involvement in rescue programs.

10.

The most important international monetary problems facing the world today are: (1) the large exchange rate volatility and disequilibria, (2) frequent economic crises in emerging in market economies (which could spread to high-income countries). Other serious international economic problems are: (1) trade protectionism in advanced countries in the context of a rapidly globalizing world, (2) deep structural imbalances in the United States, slow growth in Europe and Japan, and insufficient restructuring in transition economies of Central and Eastern Europe, (3) deep poverty in many developing countries, and (4) resource scarcity, environmental degradation, and climate change and the danger that they pose for continued growth and sustainable world development.
