Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- According to the essential-facilities doctrine, competition law requires an infrastructural monopoly to provide access. Under the "Bronner criterion", proposed by the EC Court, the doctrine is only applicable when a symmetric infrastructural duopoly is non-viable. This paper uses a simple model to illustrate that, from a welfare point-of-view, the Bronner criterion may provide too little monopoly protection for the incumbent in high-risk new markets, while requiring too much investments from the entrant in low-risk mature markets.
