This course deals with the theory and practice of international trade and of trade-related policies. It focuses on analyzing the gains from trade, the changing patterns of trade, the income distributional consequences of liberalizing foreign trade, the relationship between trade, investment, and economic growth, and the reasons for and consequences of trade policies. The course relies predominantly on a standard collection international trade models to understand the motivations behind modern trade policies. During the weekly seminar, students then analyze the efficacy of trade policy, considering both intended and unintended consequences of policy choices with particular attention paid to the changing geopolitical environment in which these policies exist.
