1. Suppose the black-and-white TV industry and the color industry are both constant cost industries. Show graphically what happens to these industries as consumer tastes shift away from black-and-white TVs to color TVs. Explain your results.

2. Assume that medical care is an increasing cost industry. Starting from LR equilibrium, suppose Congress passes a bill which grants a specific subsidy to all consumers of medical care. Given that such an action will increase demand, trace out the consequences of this subsidy to consumers using graphs and explain your results.

3. Use the numbers in Table 1 to do the following problem on farm policy.

                                                                Table 1

          P           QD0(SR)           QD1(LR)           QS0(SR)           QS1(SR)           QS2(LR)

        $20            800                     0                   1600                 1200                  2400

        $18            900                 300                   1500                 1200                  2100

        $16          1000                 600                   1400                 1200                  1800

        $14          1100                 900                   1300                 1200                  1500

        $12          1200               1200                   1200                 1200                  1200

        $10          1300               1500                   1100                 1100                    900

         $8           1400               1800                   1000                 1000                    600

         $6           1500               2100                     900                  900                     300

a. Using QD0(SR) and QS0(SR), draw a graph with a price support of $16. Indicate the ES and calculate the amount that consumers spend on the good, and the amount that the USDA spends on surpluses.

b. Assume production controls are imposed by the USDA in order to control the size of the surplus. Using QD0(SR) and one of the SR supply curves, draw a graph of this situation and indicate whether or not the USDA has managed to eliminate the surplus. Explain your result.

c. Assume the government sets a target price of $16. Using QD0(SR) and QS0(SR), draw a graph of this situation. Calculate the amount that consumers spend on the good and the USDA spends on direct payments to farmers and indicate these areas on the graph. Then calculate the welfare loss associated with this method of government subsidization and indicate the area on the graph.

d. Repeat parts a and c using QD1(LR) and QS2(LR). What do you observe about the size of the surpluses, the size of the direct payments, and the size of the welfare losses? Explain your findings.

e. Assume USDA raised the price floor (target price) to $18. If agriculture is an increasing cost industry, draw the market and firm graphs to indicate the reaction to this change in the price floor. Explain your results.
4. Assume that drugs are legalized but that they are taxed (much like alcohol is now). Start with a constant cost industry in LR equilibrium and then have the government levy a specific tax on the industry. Show graphically how this tax affects the market and how the market adjusts to the tax. Explain your graph. Also verbally explain what happens to the firm when the tax is imposed on it and how it adjusts. What would the case of a specific subsidy to producers look like?
