This paper looks at competition in the Telecommunications industry with non-linear tariffs and network based price discrimination where one of the networks has a relative advantage. We investigate profit-maximizing network pricing behaviour, in particular competitively chosen, non-cooperative...

This paper provides a limit result for the provision of a public good in a mechanism design framework as the number of agents gets large. A canonical example for a public good that is produced with a direct provision technology is Open Source Software.

This paper investigates the effect of spillovers in a model of endogenous technical change resulting from learning or network effects on the existence of a lower bound to market concentration.

This paper looks at competition in the telecommunication industry. We determine the equilibrium pricing parameters for a duopoly situation with a particular emphasis on the role of competitively chosen non-reciprocal access prices. In the symmetric equilibrium the networks optimally choose...

This paper looks at the effects of entry on welfare in the telecommunication industry. The equilibrium pricing parameters for an incumbent (state) monopoly and for a duopoly situation are determined in which access charges are chosen non-reciprocally. A welfare comparison between the monopoly...

In this paper we investigate optimal harvesting of a renewable natural resource. While in the standard approach the resource is located at a single point in space we allow for the resource to be distributed over the plane. Consequently, an agent who exploits the resource has to travel from one...

We analyse a market where newspaper publishers compete for advertising as well as for readership. Publishers first choose the political position of their newspaper then set cover prices and advertising tariffs. We build on the duopoly model of Gabszewicz et al. (2001, 2002) who show that...

This paper looks at competition in the telecommunications industry with non-linear tariffs and network-based price discrimination. Allowing for asymmetric networks and non-cooperatively chosen access prices simultaneously allows to explicitly derive non-reciprocal equilibrium access price...

In this paper we investigate the optimal harvesting of a renewable natural resource. While in most standard approaches the resource is located at a single point, we allow the resource to be distributed spatially. Consequently, an agent who exploits the resource has to travel from one location to...

Areeda and Turner (1975) were the first to argue that a price below marginal costs should be considered a sign of predation. Recognizing that marginal cost data were typically unavailable, the authors concluded that a price below average variable cost should be presumed unlawful. This so-called...
