    Abstract

    In dem Paper wird untersucht, wann ein vertikal integrierter Netzbetreiber einen Anreiz hat, durch Fordern hoher Netznutzungsentgelte den Wettbewerb im nachgelagerten Produktmarkt zu beschränken. Außerdem wird geprüft, ob und wie eine kostenorientierte Regulierung der Netznutzungsentgelte den Wettbewerb im nachgelagerten Produkt fördern kann. Es werden zwei Typen von Gleichgewichten identifiziert - markteintrittsverhindernde und markteintrittsermöglichende. Markteintrittsverhindernde Gleichgewichte existieren im unregulierten Spiel, wenn der vertikal integrierte Monopolist einen Kostenvorteil gegenüber Konkurrenten besitzt. Hat er dagegen einen Kostennachteil, dann fördert er den Markteintritt. Überraschenderweise gilt für beide Gleichgewichte, daß eine kostenorientierte Regulierung der Netznutzungsentgelte den Wettbewerb fördern kann aber nicht muß.
