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. Bankruptcy considerations ensure...

I study the capacity of business associations - private, formal, noncommercial organizations designed to promote the common business interests of their members - to support contract enforcement and collective action. Inspired by recent empirical literature, my theoretical framework connects the...

We present and analyze a novel set of enforcement data from the European Securities Market Authority during the period following the European Union's harmonized rule setting on securities market abuse. The data show significant differences in the intensity of enforcement across Europe. The...

The increased expansion of economic activity beyond national borders leads to a shift of regulatory power. Public authorities concede power, explicitly or tacitly, to private bodies, whereas the multilayered ecology of global governance inevitably increases the role of transnational...

We analyze the effectiveness of antitrust regulation in a repeated oligopoly model in which both fines and detection probabilities depend on the cartel price. Such fines are closer to actual guidelines than the commonly assumed fixed fines. Under a constant detection probability, we confirm the...

We study the timing of leniency applications using a novel application of multi-spell discrete-time survival analysis for a sample of cartels that were prosecuted by the European Commission (EC) between 1996 and 2014. The start of an EC investigation does not affect the rate at which...

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...

We analyze the capacities of communities (or social networks) and courts to secure cooperation among heterogeneous, impersonal transactors. We find that communities and courts are complementary in that they tend to support cooperation for different types of transactions but that the existence of...

We analyze the effects of antitrust and leniency programs in a repeated oligopoly model outlined in Motta and Polo (2003). We extend their framework by including the possibility of Type I judicial errors and pre-trial settlements. Through comparison of our results to the earlier results we come...

We investigate cartelists’ merger behavior using European Commission (EC) cartel decisions over a 28-year span and information on cartelists’ merger activities over the last 30 years. We find that mergers occur frequently. But they cluster in a few particular industries and usually include...
