Empirical Industrial Organization


Objectif

The aim of the course is to give a solid grounding in the modern empirical tools that are useful in understanding the structure of markets, and the strategic behavior of firms and their consumers.The course covers discrete choice and static demand estimation, consumer search, and static models of entry and market structure. The course also provides a hands-on introduction to MATLAB, with applications to the estimation of static demand systems and entry models.

Grading

Students are expected to prepare for and actively participate in all lectures and computer sessions.The grade for this course is based on presentations of assigned papers (20%), (computational) problem sets (30%) and a final home assignment (50%).

a) Presentations: Lecture material will be mainly based on those references with [*] (see below the list of topics and references). For each topic, students will make a 30–minute presentation about a randomly assigned paper related to the topic previously discussed in class.

b) Problem Sets: There will be 2 problem sets. They will entail substantial empirical and computational exercises. Students can work in groups but each student should send an individual code. Randomly selected students will be asked to discuss their problem sets’ solutions during class (i.e., codes and results).
