The course provides an introduction to the economics of antitrust. With the use of basic tools of industrial organization, we will analyze the main aspects of competition policy, such as collusive agreements, mergers, vertical restraints and abuse of dominance. These issues will be discussed also with reference to recent antitrust cases. Students will actively participate by studying and discussing case studies. At the end of the course, students will be able to critically interpret the main policy issues in the field of antitrust
