      Prob 10 3c. Calculate the overall net effect of the export subsidy on Home welfare.
  4. Refer to Problem 3. Rather than a small exporter of wheat, suppose that Home is a large country. Continue to assume that the free-trade world price is $100 per ton and that the Home government provides the domestic producer with an export subsidy in the amount of $40 per ton. Because of the export subsidy, the local price increases to $120, while the foreign market price declines to $80 per ton. Use the following figure to answer these questions.

  5. Refer to Problem 3. Suppose Home is a small exporter of wheat. At the world price of $100 per ton, Home growers export 20 tons.

    Prob 9 6. Explain why the WTO is more concerned with the use of direct export subsidies than production subsidies in achieving the same level of domestic support.
  7. Boeing and Airbus are the world’s only major producers of large, wide-bodied aircrafts. But with the cost of fuel increasing and changing demand in the airline industry, the need for smaller regional jets has increased. Suppose that both firms must decide whether they will produce a smaller plane. We will assume that Boeing has a slight cost advantage over Airbus in both large and small planes, as shown in the payoff matrix below (in millions of U.S. dollars). Assume that each producer chooses to produce only large, only small, or no planes at all.

      Prob 10 7b. Are there multiple equilibria? If so, explain why. Hint: Guess at an equilibrium and then check whether either firm would want to change its action, given the action of the other firm. Remember that Boeing can change only its own action, which means moving up or down a column, and likewise, Airbus can change only its own action, which means moving back or forth on a row.

  9. Here we examine the effects of domestic sales taxes on the market for exports, as an example of the “targeting principle.” For example, in the domestic market, there are heavy taxes on the purchase of cigarettes. Meanwhile, the United States has several very large cigarette companies that export their products abroad.
