Introduction to the course:

The first part of the course will be devoted to explaining the work of perfectly competitive markets. This provides a benchmark against which it is possible to assess other (more realistic) market structures. The second part of the course will focus on departures from perfectly competitive markets, such as monopoly, monopolistic competition, and oligopoly. Basic notions of game theory will be introduced and used to solve some real world cases.
