Objectifs du cours

This course allows students to continue to learn and use concepts and tools in Microeconomics. It focuses on firm behavior and industrial organization.

It mixes theory and applications (tutorials). Most of the concepts will be investigated using various formats: verbal descriptions, graphic representations, mathematics, applications.

After reviewing/going further in the understanding of firm behavior under perfect competition, we will focus on imperfect competition. Using the tools of profit maximization developed in the theory of the firm, we investigate the monopoly as well as Monopolistic Competition. We then study major models of oligopolies, including models by Cournot, Stackelberg, Bertrand, as well as collusive behavior.

The basics of Game Theory are finally presented to find dominant strategies and Nash equilibria to explain strategic interactions among firms and predict market outcomes.
