How do individual citizens, organized groups, and political parties react to the internationalization of economic activity? Who promotes it and who fights against it? Who is more likely to be successful and who is more likely to fail in the pursuit of their goals? To answer these questions this course offers a historical introduction to international political economy. It is organized around three main sections. First, we present the most important theories and methods used to learn about the politics of international economics. Second, we use the theories and methods covered in the first section to review major developments in international economic relations from the 1860s to today. We focus mostly on three areas: international trade, international monetary relations, and international migration flows. Finally, we conduct original research, aiming to produce altogether new knowledge about the politics surrounding international economic developments
