Learning outcomes

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

Course contents

The course is organized with a part of lectures taught online on MS TEAMS (20 hours) and another taught in presence (20 hours). The number of students allowed in class is determined on the basis of class capacity and by the health and safety provisions that deal with the pandemic emergency. In case more students want to attend classes in presence than permitted by the rules, a system of shifts will be organized so to allow students to participate. Regardless of the health-related conditions and the specific organization of the course, students will be able to follow the lessons of the entire course remotely on MS TEAMS.
