COFOLA INTERNATIONAL 2019 focused on the Private Enforcement of Antitrust Law and Unfair Competition with Cross-border Element. Same as in previous years the participants from several countries had very lively discussions and covered various current and interesting topics. The conference proceedings unfortunately contain only a limited number of papers. There were more applications to the conference and more oral presentations. Only the following papers have been submitted in written form and have been recommended by reviewers for publication.
