We revisit the pros and cons of cartel criminalization with focus on its possible introduction in the EU. We document a recent phenomenon that we name EU ``leniency inflation", whereby leniency has been increasingly awarded to many, and sometimes all members of a cartel. We argue that, coupled...

Modern antitrust engenders a possible conflict between public and private enforcement due to the central role of Leniency Programs. Damage actions may reduce the attractiveness of Leniency Programs for cartel participants if their cooperation with the competition authority increases the chance...

This paper provides a systematic analysis of identification in linear social interactions models. This is both a theoretical and an econometric exercise as the analysis is linked to a rigorously delineated model of interdependent decisions. We develop an incomplete information game that...

While interest in social determinants of individual behavior has led to a rich theoretical literature and many efforts to measure these influences, a mature "social econometrics" has yet to emerge. This chapter provides a critical overview of the identification of social interactions. We...

Following Bernheim and Whinston (1990), this paper addresses the effects of multimarket contact on firms' ability to collude. Real world imperfections tend to make firms' objective function strictly concave and market supergames "interdependent": firms' payoffs in each market depend on how they...

We consider two ascending auctions and show that many of the (unwanted) collusive or signaling equilibria studied in the literature in the framework of the SEAMO (simultaneous English auction for multiple objects) don't have a counterpart in the JAMO (Japanese auction for multiple objects). We...
