This course explores the economic interdependence among the nations of the world.  International Trade theory builds on material presented in Microeconomics (EC202), while International Finance builds in a similar way on Macroeconomics (EC201).  The first half of the course is devoted to the theory of International Trade. We will examine why nations trade with one another and the consequences of such trade. We will also look at the consequences of interfering with free trade through the use of tariffs, quotas, or other barriers to trade.  We will focus on such topics as the market for foreign exchange, the balance of payments, and the international transmission of business cycles.
