The aim of the class is to enable students to go through advanced topics in international economic integration. Mainstream recent theoretical and empirical contributions on trade will be presented. Specific emphasis will be devoted to trade policies, income distribution and welfare effects of trade restrictions, trade and environment, geographic agglomeration. The last section of the lectures will dwell on social choices and/or political economy of trade.

Teaching methods

On-campus teaching with full set of video recorded lectures available on the Microsoft Stream platform. Please visit the dedicated website.

Assessment methods

The exam consists of two sections, A (theory) and B (empirics). Students need to answer to two out of three questions from section A, and to the question in section B. The exam consists of commenting and explaining the analytical relations and econometric output tables that were presented during the class. The exam does not involve the derivation of any analytical result, but it requires only to comment and explain.

Old exam questions are available for students at this link.

In case of a positive final mark the student has the right to renege on the mark only once.

Teaching tools

Lecture Notes are created with Microsoft OneNote and are immediately shared with students.

Video recorded lectures are available on the Microsoft Stream platform. Please visit the dedicated website.
