7.4 Import Tariffs: Large Country Price Effects LEARNING OBJECTIVES 1. Identify the effects of a specific tariff on prices in both countries and the quantity traded. 2. Know the equilibrium conditions that must prevail in a tariff equilibrium. Suppose Mexico, the importing country in free trade, imposes a specific tariff on imports of wheat. As a tax on imports, the tariff will inhibit the flow of wheat across the border. It will now cost more to move the product from the United States into Mexico. As a result, the supply of wheat to the Mexican market will fall, inducing an increase in the price of wheat. Since wheat is homogeneous and the market is perfectly competitive, the price of all wheat sold in Mexico, both Mexican wheat and U.S. imports, will rise in price. The higher price will reduce Mexico’s import demand. The reduced wheat supply to Mexico will shift back supply to the U.S. market. Since Mexico is assumed to be a large importer, the supply shifted back to the U.S. market will be enough to induce a reduction in the U.S. price. The lower price will reduce the U.S. export supply. For this reason, a country that is a large importer is said to havemonopsony power in trade. A monopsony arises whenever there is a single buyer of a product. A monopsony can gain an advantage for itself by reducing its demand for a product in order to induce a reduction in the price. In a similar way, a country with monopsony power can reduce its demand for imports (by setting a tariff) to lower the price it pays for the imported product. Note that these price effects are identical in direction to the price effects of an import quota, a voluntary export restraint, and an export tax. A new tariff-ridden equilibrium will be reached when the following two conditions are satisfied: PMexT=PUST+T and XSUS(PUST)=MDMex(PMexT), where T is the tariff, PTMex is the price in Mexico after the tariff, and PTUS is the price in the United States after the tariff. The first condition represents a price wedge between the final U.S. price and the Mexican price equal to the amount of the tariff. The prices must differ by the tariff because U.S. suppliers of wheat must receive Saylor URL: http://www.saylor.org/books Saylor.org 312
