Problem 5 The Dairy Farm Company, a small producer of milk and cheese, has estimated the quantities of milk and cheese that it can produce with three levels of total expenditures or total costs. These are indicated in the following table. If the price of milk (product A) and the price of cheese (product B) that the firm receives are $ 1 each per unit of the products, draw a figure showing the maximum total profi t (p) that the firm can earn at each level of TC and the overall maximum profit that the firm can earn for the three different levels of TC. Problem 12: a) Will a monopolistâ€™s total revenue be larger with seconddegree price discrimination when the batches on which it charges a uniform price are larger or smaller? Why? b) How does a two-part tariff differ from bundling?
Spreadsheet Problem 1: Using a spreadsheet like the following, entering formulas for the total revenue and consumers surplus, and given the following demand curve of a consumer for a monopolist product Q=14-2p a) Find the total revenue of the monopolist when it sells 6 units of the commodity without practicing any form of discrimination.

Froeb et al.’s Chapter 14: a) Individual problems: 14–1 and 14–4. Individual Problem 14-1: Why might Mattel set a much lower contribution margin on its Barbie dolls than on the accessories for the dolls?
Individual Problem 14-4: A manufacturer of microwaves has discovered that male shoppers have little value for microwaves and attribute almost no extra value to an auto-defrost feature. Female shoppers generally value
microwaves more than men and attribute value to the auto-defroster feature. There is little additional cost to incorporating auto defrost feature. Since men and women cannot be charged different prices for the same product the manufacturer is considering introducing two different models. The manufacturer has determined that men value a simple microwave at $70 and one with auto defrost at $80 while women value a simple microwave at $80 and one with auto defrost at $150. If there is an equal number of men and women, what pricing strategy will yield the greatest revenue? What if women compromise the bulk of microwave shoppers?

Discussion Question 12: What is the rationale behind the minimax regret rule? What are some of the less formal and precise methods of dealing with uncertainty? When are these useful? Discussion Question 15: How does the adverse selection problem arise in the credit-card market? How do creditcard companies reduce the adverse selection problem that they face? To what complaint does this give rise? Spreadsheet Problem 1: An individual has to choose between investment A and investment B. The individual estimates that the income and probability of the income from each investment are as given in the following table.
Investment A Investment B Income Probability Income Probability 4,000 0.2 4,000 0.3 5,000 0.3 6,000 0.4 6,000 0.3 8,000 0.3 7,000 0.2
Using Excelâ€™s statistical tools, calculate the standard deviation of the distribution of each investment. Which of the two investments is more risky? Which investment should the individual choose? Spreadsheet Problem 2: An individual is considering two investment projects. Project A will return a zero profit if conditions are poor, a profit of $4 if conditions are good, and a profit of $8 if conditions are excellent. Project B will return a profit of $2 if conditions are poor, a profit of $3 if conditions are good, and a profit of $4 if conditions are excellent. The probably distribution of the conditions is as follows:
Conditions: Poor Good Excellent Probability 40% 50%
Using Excel, calculate the expected value of each project and identify the preferred project according to this criterion. Assume that the individual’s utility function for profit is U(X) =X-0.05X2. Calculate the expected utility of each project and identify the preferred project according to this criterion. Is this individual risk adverse, risk neutral, or risk seeking? Why? Froeb et al.’s Chapter 17: a) Individual problems: 17–1 and 17–4. Individual Problem 17-1: You’re the manager of global opportunities for a US manufacture, who is considering expanding sales into Europe. Your market research has identified three potential market opportunities: England, France, and Germany. If you enter the English market, you have a 0.5 chance of a big success (selling 100,000 units at a per-unit profit of $8), a 0.3 chance of moderate success (selling 60,000 units at a per-unit profit of $6), and a 0, 2 chance of failure (selling nothing). If you enter the German market, you have a 0.2 chance of huge success (selling 150,000 units at a per-unit profit of $10), a 0.5 chance of moderate success (selling 70,000 units at a perunit profit of $6), and a 0.3 chance of failure (selling
nothing). If you can enter only one market, and the cost of entering the market (regardless of which market you select) is $250,000, should you enter one of the European markets? If so, which one? If you enter, what is your expected profit? Individual Problem 17-4: Your company has a customer who is shutting down a production line, and it is your responsibility to dispose of the extrusion machine. The company could keep it in inventory for possible future product and estimates that the reservation value of $250,000. Your dealings on the second-hand market lead you to believe that these is a 0.4 chance a random buyer will pay $300,000 a 0.25 chance the buyer will pay $350,000, a 0.1 chance the buyer will pay $400,000, and a 0.25 chance it will not sell. If you must commit to a posted price, what prices maximizes profit? Froeb et al.’s Chapter 19: b) Individual problems: 19–5 and 19–6. Individual Problem 19-5: Soft selling occurs when a buyer is skeptical of the usefulness of a product and the seller offers to set a price that depends on realized value. For example, suppose you’re trying to sell a company a new accounting system that will reduce costs by 10%. Instead of naming that price, you offer to give them the product in exchange for 50% of their cost savings. Describe the information asymmetry, the adverse selection problem, and why soft selling is a successful signal.
Individual Problem 19-6: You need to hire some new employees to staff your start-up venture. You know that potential employees are distributed throughout the population as follows, but you canâ€™t distinguish among them: Employee Value Probability $50,000 0.25 $60,000 0.25 $70,000 0.25 $80,000 0.25 What is the expected value of five employees you hire? Salvatore's Chapter 15: a) Discussion Questions: 7. b) Problems: 8, 10, and spreadsheet problem 1.
Discussion Question 7:
a) When can the NPV and the IRR methods of evaluating investment projects provide contradictory results? b) How can this arise? c) Which method should then be used? Why? Problem 8: John Piderit, the general management of the Western Tool Company, is considering introducing some new tools to the companyâ€™s product line. The top management of the firm has identified three types of tools (referred to as projects A, B, and C). The various divisions of the firm have provided the data given in the following table on these three possible projects. The company has a limited capital budget of $2.4 million for the coming year. a) Which project(s) would the firm undertake if it used the NPV investment criterion? b) Is this the correct decision? Why? Problem 10: The MacBurger Company, a chain of fastfood restaurants, expects to earn $200 million after taxes for the current year. The company has a policy of paying out half of its net after-tax income to the holders of the companyâ€™s 100 million shares of common stock. A share of common stock of the company current sells for eight times current earnings. Management and outside analysts expect the growth rate of earnings and dividends for the company to be 7.5 percent per year. Calculate the cost of equity capital to this firm.
Spreadsheet Problem 1: The benefits and costs of an investment project (the purchase of a piece of machinery) are those given in the following table. In excel, calculate the net revenue, or the revenue from the investment minus the costs; the present value coefficient for every year, and the present value of the net revenue. Add together column F to get the net present value of the project. Should the firm purchase the machine? =========================================== ===
