Abstract

Nous présentons dans ce papier une modélisation du seuil critique de préférence pour la collusion dans un duopole mixte/privé en fonction du tarif d’interconnexion et de son coût marginal, dans un régime de concurrence à la Cournot. L’objectif consiste à comparer la préférence pour la collusion à travers ce seuil dans les deux structures de marché étudiées et dans deux cas de figures : coûts d’interconnexion linéaires et coût d’interconnexion quadratiques. Les résultats montrent que le seuil dépend de deux variables : Le tarif d’interconnexion et un paramètre relatif à la technologie employée par l’opérateur. Les résultats de l’application au cas du marché Tunisien sont conformes aux résultats théoriques.
