International Trade (L3)

This course will provide students with the analytical tools that are essential to understand the process of globalization through the international trade in goods. Lectures will focus on the key topics that are at the center of the policy debate: why do countries open to trade? What are the effects of free trade on the process of economic development and inequality? Why do countries restrict the exchange of goods, and what can we say about the effects of protectionism on trade and welfare?

At the end of the course, students are expected to have a good knowledge of the mechanisms and predictions from the traditional models of trade, and from the New Trade Theory.  Students will also be able to read simple research articles that can be used for the writing of policy notes.

The lectures will be organized as follows: the lectures will be designed to treat the main topics of the course. The first part of the course will give an overview of the main theories in international trade. The second part of the course covers gravity equations as a tool for analyzing trade integration, and economic geography that has been an important component of recent international economic analysis. Two important research topics will close the lecture: how globalization affects military conflicts and cultural patterns.


Grades are based a tutorial exam (50%) and a final exam (50%).
