Based on a sample of 64 cartels convicted by the European Commission from 1975 to 2009 and a methodology allowing to estimate restitution and dissuasive fines to be imposed on cartels from microeconomic variables on a case by case basis, this paper compares the level of fines actually inflicted...

An antitrust authority deters collusion using fines and a leniency program. Unlike in most of the earlier literature, our firms have imperfect cumulative evidence of the collusion. That is, cartel conviction is not automatic if one firm reports: reporting makes conviction only more likely, the...
