Abstract : This paper studies the interplay between the optimal evidentiary standard and the optimal (de)coupling between payment and award upon trial in the context of private antitrust enforcement with asymmetric information on the true type of the defendant. We equally examine the consequences, also in terms of expected welfare, of introducting public enforcement into the framework. We show that allowing for public enforcement always leads to a lower optimal standard of evidence. This may only enhance welfare if the information available is good enough.
