Background

About Fabian Rinnen

I am a competition economist with extensive experience in a wide range of quantitative techniques. While the focus of my work is on the econometric estimation of cartel damages, I also advise national and international clients on other areas of competition policy, including antitrust, mergers, economic and financial regulation. During my career, I have advised numerous clients across a range of sectors including building materials, drug store products, food retail, industrial gases, oilfield services, financial services, steel, automotive and transportation. These include multinational companies such as Haliburton, METRO, Suez, Reckitt Benckiser, Veolia, Volkswagen or Zentis as well as various small and medium sized companies that are leaders in their respective fields. Recently, I provided expert advice to a defendant in a high profile cartel proceeding in the power cables industry and I represent the alleged ringleader, a major construction company, in Austria‘s largest-ever cartel probe before the Kartellgericht. Besides various ongoing cartel damages proceedings before German Courts in which claimants and defendants continue to rely on my expertise, I most recently applied my econometric knowledge to the estimation of the harm suffered by the clients of roll-on/roll-off shipping companies and the Europe-wide trucks cartel before the Competition Appeals Tribunal. I further advised METRO in its proposed sale of the German food retailer Real before the Federal Cartel Office. In my recent research, I have investigated the intersection of legal and economic concepts when quantifying cartel damages, both in terms of econometric techniques as well as ad hoc estimation by a judge. Apart from my published articles, I have shared insights in the form of blog posts, podcasts and presentations to peers and clients that cover a broad range of competition topics. Since 2019 I have repeatedly been named in Who’s Who Legal: Competition and Who’s Who Legal: Consulting Experts as one of Germany’s “Future Leaders” in competition economics. I am a member of the Studienvereinigung Kartellrecht, the German Competition Litigation Forum and the German Arbitration Institute.
