This seminar course focuses on competition enforcement from both legal and economic perspectives. The objective of the course is to provide an introduction to the economic analysis and the legal framework that is relevant to different areas of enforcement and discuss the interplay between them, in part through the discussions of recent cases. Topics addressed include: collusion, cartels, exchanges of information, other horizontal agreements (including patent settlements involving reverse payments) vertical agreements, abuse of dominance (including tying, bundling, rebates and injunctions) land mergers. Extracts from textbooks and selected readings will be assigned. Students will be expected to participate actively in class and present some cases.
