Abstract
This paper deals with the enforcement of merger policy, and aims to study how merger emedies affect the deterrence accomplished by controlling mergers. We determine the optimal frequency of investigations launched by the agency, and identify situations where the introduction of remedies can lead to a lower welfare. We find that the potential for remedies can make it less likely that the worst mergers are deterred. Even if the worst mergers are deterred, the potential for remedies can lead to more mergers with a negative impact to be proposed, and eventually to more decision errors by the antitrust authorities.
