Retail markets, especially food retail, pose a lot of different challenges to competition authorities as they are frequently investigated and always meet high public interest. The seminar will provide a better understanding of market definition and methodology, topics in merger control (oligopolistic markets, buyer power), vertical restraints (exclusive dealing, RPM), special phenomena such as category management and will also provide insights into sector inquiries. The topics will be addressed and discussed in lectures by competition experts from OECD countries and in case studies presented by the participants.
