International trade has always been economically controversial and politically contentious. This course demystifies some of the complex issues that surround discussions of globalization. It asks such questions as: Why do countries engage in trade? Are countries in competition with one another, making one a winner and another a loser, or is trade mutually beneficial? Who gains and who loses from international trade within any given country? Should high-wage countries be worried about competition from low-wage countries? Should low-productivity countries be worried about competition from high-productivity countries? Is international trade the main cause of increasing U.S. wage inequality? How do global supply chains affect firms and workers within a country? How is the burden of import tariffs divided in the economy? Do international trade agreements create jobs or destroy jobs? What is the impact of a trade war on the global economy? This course examines these questions and much more.
