Délégation ou centralisation des décisions. L'impact sur la collusion


  • Thierry Pénard


[fre] Cet article analyse l'impact d'une centralisation ou d'une délégation des décisions de prix sur les possibilités de collusion entre firmes. La finalité est de montrer que l'intensité concurrentielle sur un marché dépend plus du nombre de décideurs en prix que du nombre de firmes présentes sur ce marché. Lorsque les firmes font face à une demande aléatoire et sont en contact sur plusieurs marchés, une centralisation des décisions (une réduction du nombre de décideurs) est plus favorable à la collusion, car elle permet de réduire le coût de dissuasion des baisses de prix secrètes. Ce résultat est renforcé lorsque la centralisation impose un délai entre deux révisions de prix. L'intérêt de cet article est aussi d'éclairer les pratiques qui facilitent la collusion en information imparfaite. [eng] Centralization of pricing decisions and collusion. . . This paper compares the feasibility of tacit collusion when pricing decisions are either centralized or decentralized. The intuition is that the number of pricing decision makers on a market is likely to have more impact on the price competition than the number of firms. When the firms face a random demand and have multimarket contacts, we prove that centralization is more collusive than decentralization because it reduces the cost of price-cutting dissuasion. This result is reinforced if centralization decreases the frequency of price revision. Finally, this study emphasizes some practices that can facilitate collusion with imperfect monitoring.
