Institution: Toulouse School of Economics
Session: Spring 2024
Teachers: Isis Durrmeyer, Bruno Jullien and Patrick Rey
This is a course in the Graduate Industrial Organization sequence. We aim to give a solid grounding in understanding the structure of markets, and the strategic behavior of firms and their consumers. This course has three parts:
- Vertical relations (Patrick Rey).
- Two-sided markets (Bruno Jullien).
- Empirical methods and research topics in industrial organization at the frontier of the empirical IO research (Isis Durrmeyer)
