Graduate Institute of International and Development Studies

EI064 - Spring 2022 - Course- 6 ECTS

Wednesday 16:15-18:00

Lecturer: Yuan Zi
Office hours: Thursday 10:00-12:00 (class weeks)

Course Description

This course is designed for MIS economics students as well as for policy-oriented Masters students specializing in economics. It covers advanced empirical topics in international trade (as well as economic geography) and problem sets related to the lectures. The course is divided into four parts. The first part considers testings on predictions of the neoclassical trade theories and their implications. The second presents empirical evidence on new trade models with imperfect competition and economic geography. The third part considers firms in international trade and gravity equations. The last covers facts and empirical works on trade policies. Students should be comfortable with basic econometric analysis.

Goals

After the course, you should be able to address positive issues, such as: Why do countries trade? What goods do countries trade? What are the implications of openness for the location of production, industries, occupations, and innovative activity? And, what impedes trade and why do some countries deliberately erect policy impediments to trade? You should also be able to offer your thoughts on normative issues, such as: Is trade openness beneficial to a representative agent? And, Are there winners and losers from trade and if so, can we identify them? You should be able to develop your answers to above questions under a neoclassical setting as well as those with market failures, at the industry level as well as the firm-level, and in the presence of both mobile and immobile factors.

Main textbooks

Additional textbooks

  • Helpman, E. & Krugman P., 1985: Market Structure and Foreign Trade, MIT Press.
  • Combes, P.-P., Mayer, T. and Thisse, J., Economic geography, Princeton University Press.

NB:

It is sufficient to understand what covers in the course. Students are encouraged to use the listed textbooks and references to enhance their understanding of course materials when needed.

We all have different backgrounds and prefer different learning styles. Student are encouraged to use google or the library for fragmented learning materials when a question arises. Don't read a whole textbook when you are confused about one particular thing - it is usually not very helpful and surely not efficient!

Pre-requisites of the course

The course assumes knowledge of basic micro theory (part 1 of MMKM textbook), and basic econometrics (i.e. Econometrics I).

Grading

The grade will be based on an applied group work (25% of the final grade), a paper presentation (25% of the final grade) and a final exam (50% of final grade).

  • Applied work: To be done by group, and will be based on a practical application using the gravity equation.
  • In class presentation: The presentation should be based on one of the paper of the reading list (see below). They should be organized as follows: presentation of the paper, then discussion of the paper, i.e. description of its main features, contributions to the literature, strengths and weakness.
