This course is intended as the first International Trade course at the undergraduate level. It focuses on all those questions students have when they take an international trade course. The main goal is to teach students how professional international economists think, specifically, the development of comfort with the approaches that international economists use to problems, a technical and intuitive mastery of the important theorems and a technical and intuitive mastery of how to approach important policy problems. The theory is necessary and the policy implications are extremely important for economic welfare. When this course is over the student should have an understanding of important ideas in international trade and mastery of approaches to solving problems which we have not explicitly dealt with.
