This course focuses on the economics of industry. After a brief introduction to game theory, focusing on concepts commonly used in industrial organisation, we discuss static and dynamic aspects of imperfection competition and the sources of market power. We then study price discrimination and the economics of networks and platforms. For each topic, the course will consider the main theoretical developments as well as applications. We will use the textbook 'Industrial Organisation. Markets and Strategies' by P. Belleflamme and M. Peitz (CUP, 2015) as the main reference.
