This program addresses recent debates at the frontier of the field: globalization, the distributive effects of trade, the role of large firms in the global economy, advances in methods to analyze firm level export data and finally the revival of trade policies.

The courses revolve around the following questions. What are the quantitative models to be used in international trade to gauge welfare and other responses to counterfactual shocks? What are the consequences of globalization on income distribution? Why are firms that export not only the most productive but also sell products at higher prices (unit values) on the export market? What are the recent developments in the political economy of trade policy? How can quantitative trade models be used to evaluate the impact of an economic dis‐integration shocks such as Brexit? How do tax and trade policies interact when multinational firms are engaged in profit shifting activities? How can we quantify the effects of trade and other policies with the gravity model?


Participants will learn about the very recent developments in both theory and empirics of international trade.

« Lectures from professors were really interesting! And I got insightful advises from professors. » Malo, 2018
