Hipster Antitrust calls for the outright rejection of the consumer welfare standard as the lodestar of antitrust law in favor of a vague “public interest” test that requires courts and agencies to consider a variety of social and political goals. It also advocates for focusing antitrust...

Between September 2014 and September 2016 high courts in multiple jurisdictions released five decisions that address applying competition law to matchmakers that operate virtual or physical platforms for connecting multiple groups of customers. The decisions rely, directly or indirectly, on the...

We study antitrust enforcement that channels price-fixing incentives through setting fines and allocating resources to detection activities. Antitrust fines obey four legal principles: punishments should fit the crime, proportionality, bankruptcy considerations, and minimum fines. Bankruptcy...

This paper develops a model of the birth and death of cartels in the presence of enforcement activities by a Competition Authority (CA). We distinguish three sets of interventions: (a) detecting, prosecuting and penalizing cartels; (b) actions that aim to stop cartel activity in the short-term,...

We study antitrust enforcement in which the fine must obey four legal principles: punishments should fit the crime, proportionality, bankruptcy considerations, and minimum fines. We integrate these legal principles into an infinitely-repeated oligopoly model, where bankruptcy considerations...
