The goal of a cooperative equilibrium in an optimal tariff game between two countries is for both countries to set zero tariffs—that is, to choose free trade. The Nash equilibrium in an optimal tariff game between two countries is a ìprisoner’s dilemmaî outcome because there is another set of strategies (not chosen) that could make both countries better off. The WTO, and the GATT before it, represents mechanisms by which countries can achieve the cooperative equilibrium. EXERCISES 1. Jeopardy Questions. As in the popular television game show, you are given an answer to a question and you must respond with the question. For example, if the answer is “a tax on imports,” then the correct question is “What is a tariff?” 1. The term used to describe a country’s countertrade actions in response to its trading partner’s increase in tariffs. 2. The name given to a noncooperative solution to an economic game. 3. The term used to describe an economic game equilibrium that maximizes the sum of the payoffs to all players. 2. Consider the following trade policy game between two small country governments, Kenya and Ethiopia. The policy choices for each government are either to choose free trade on all imports or to place a 15 percent tariff on all imports. The national welfare payoffs for each country when both choose free trade are given as (100, 100). The first 100 is Kenya’s national welfare; the second is Ethiopia’s.

1. Based on the tariff analysis for a small importing country and assuming symmetry between the two countries, complete the empty two cells in the table above. 2. Based on the numbers you provided in part a, identify which cell corresponds to the Nash (or noncooperative) equilibrium. 3. Which cell corresponds to the cooperative equilibrium? 4. Does this game help justify a trade liberalization organization like the WTO? 3. Suppose the United States (US) and Costa Rica (CR) are two countries among many others in the world. The US is a large country and thus its import tariffs will lower the price of CR’s exports. CR, however, is a small country, so its tariffs do not affect prices in the US. Assume the US government can choose free trade, optimal tariffs, or 20 percent tariffs. CR can choose free trade, 10 percent tariffs, or 20 percent tariffs on all imports. The national welfare payoffs for each country in five cases are given. The first term is the US’s national welfare; the second is CR’s.
