Abstract [en]

This article surveys, discusses and classifies methods for ex-post evaluation of the efficiency of competition authorities: court appeals, peer reviews, case studies, event studies, (authorities’ own) bottom-up calculations of consumer gains, deadweight-loss estimates, cross-country panel studies etc. Based on empirical estimates from other types of studies and on a simple oligopoly model, one conclusion is that many bottom-up calculations are based on exaggerated estimates of gains from cartel enforcement, relative to those from merger enforcement. Another conclusion is that authorities’ ex-post self evaluations are of limited value, relative to external evaluations.
