This course covers the major theories of international trade, including mercantilist, Ricardian, neoclassical, neo-Ricardian, technology gap, unequal exchange, and Marxian models. It focuses on determinants of the direction of trade and potential gains from trade, and on the links between international trade, income distribution, employment, and economic growth. Emphasis is placed on empirical tests of the theories. Other topics include intra-university and intra-firm trade, and strategic trade policy issues, including labor and environmental standards.
