This paper studies the impact of a dominant firm's conditional discounts on competitors' learning-by-doing. In a vertical context where a dominant upstream supplier and a competitive fringe sell their products to a single downstream firm, we analyze whether the dominant supplier prefers to offer...

This paper investigates the contractual choice between exclusive dealing and common agency in a simple international oligopoly model where products are sold through intermediaries. We find that when trade barriers are high domestic firms tend to adopt exclusive dealing contracts, whereas trade...

The paper introduces a specification of the demand side which allows RPM to have different effects on prices and on service, which may increase or decrease due to RPM. A feature of the model which deviates from those found in the literature is due to the introduction of a class of consumers who...

Proponents of RPM argue that RPM helps to sustain a high level of service at the point of sale and that such a high level is efficient. This paper provides a simple model which leads to the following conclusions: 1) RPM may increase or decrease the level of service. 2) Whether the service level...

In dem Paper wird untersucht, wann ein vertikal integrierter Netzbetreiber einen Anreiz hat, durch Fordern hoher Netznutzungsentgelte Wettbewerber vom Strommarkt fernzuhalten (Preisstrukturmißbrauch). Es wird als kontraintuitives Ergebnis abgeleitet, daß ein Kostennachteil des Netzbetreibers...

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...

Under ex ante access regulation entrants often claim that access fees are excessive. I show that this is only the case if further entry is admitted. If the entrant is protected from further entry it would agree with the incumbent upon a strictly positive access fee which may exceed the efficient...

Within the last three years, Google has acquired YouTube and DoubleClick and has attempted to control part of Yahoo!'s search advertising business. Two of the deals have not raised antitrust concerns by competition authorities. I review these deals with a focus on consumer welfare. Consumers are...

This paper examines how the option of a regulated linear input price affects vertical contracting, where a monopolistic upstream supplier sequentially offers supply contracts to two symmetric downstream firms. We find that equilibrium contracts vary with production cost and regulated price...
