On 23rd and 24th October 2025, experts in competition law and economics from academia and practice based in Germany and abroad contributed to this year's MaCCI Law & Economics Conference "Advances in Competition Law and Policy". The conference took place in honor of the former director and member of the Advisory Board of MaCCI, Heike Schweitzer who passed away last year and featured presentations ranging from the foundation of competition law to digital market regulation and industrial policy. The rector of the University of Mannheim, Thomas Fetzer, and the president of the ZEW, Achim Wambach, reflected on the contributions by Heike Schweitzer in their opening and closing remarks. The annual MaCCI Law & Economics Conference provides an international platform for exchange and discussion between academic researchers and practitioners in public authorities, legal counsel, and economic consultancies.
