Antitrust policy and price collusion : public agencies vs delegation
Published online by Cambridge University Press: 17 August 2016
Summary
This paper investigates the effectiveness of antitrust policy in fighting horizontal collusion under different regimes of policy implementation. We consider two regimes: a public agency regime, where an antitrust authority is in charge of competition policy, and a “delegation” regime, where the policy is chosen by consumers. In both regimes the policy is implemented under discretion. The analysis shows that delegation dominates, both in case of complete and imperfect information about production costs, the public agency regime because consumers credibly start off an higher level of investigation activity than the public agency. This result implies that the public agency will fight the cases involving “relevant” anti-competitive activities, while consumers will act also against “minor” violations. The combination of the two regimes yields an higher welfare than having only a public agency in charge of competition policy, because consumers can partially relax the agency's limited resources constraint.
Résumé
Cet article étudie l'efficacité d'une politique antitrust combattant la collusion horizontale sous différents régimes de mise en oeuvre. Nous considérons deux régimes : un régime avec agence publique, où une authorité antitrust se charge de la politique de concurrence, et un régime de « délégation », où la politique est choisie par les consommateurs. Sous les deux régimes, la politique est mise en oeuvre à discrétion. L'analyse montre que la délégation domine l'agence publique, dans le cas d'une information complète comme imparfaite sur les coûts de production, parce que les consommateurs mettent en place une activité d'investigation d'un plus haut niveau. Ce résultat implique que l'agence publique va combattre des cas « importants » d'activités anti-concurrencielle, alors que les consommateurs vont aussi agir face à des cas plus « mineurs ». La combinaison des deux régimes mène à un meilleurs bien-être que si une agence publique seule est en charge de la politique concurrentielle, parce que les consommateurs peuvent partiellement relacher la contrainte des ressources limitées de l'agence.
