In this paper I investigate a Bayesian inverse problem in the specific setting of a price setting monopolist facing a randomly growing demand in multiple possibly interconnected markets. Investigating the Value of Information of a signal to the monopolist in a fully dynamic discrete model employing the Kalman-Bucy-Stratonovich filter, we find that...

In standard models of spatial harvesting, a resource is distributed over a continuous domain with an agent who may harvest everywhere all the time. For some cases though (e. g., fruits, mushrooms, algae), it is more realistic to assume that the resource is located at a fixed point within that domain so that an agent has to travel in order to be abl...
Article
In this paper, we focus on the exploitation of a renewable resource in a spatial setting. Building upon the spatial harvesting model of Behringer and Upmann (2014), we endogenize the price for the resource assuming that after harvesting the good is non-durable, i.e. the harvesting yield must be supplied on the market instantaneously. We find necess...

This paper considers collusion between asymmetric networks in the telecommunications industry. Its primary purpose is to fill the gap between the literature on collusion between asymmetric firms and the literature on collusion in the telecommunications industry. Employing the standard Hotelling framework of horizontal product differentiation with n...

We extend modern Walrasian economics, and in particular the results on Cournot convergence and dynamics, by focusing on renewable resources in a spatial setting. Building on the harvesting model of Behringer and Upmann (2014) we endogenize prices and investigate the two cases of durable and non-durable renewable commodities. We find that endogenizi...
Article
We model an economy of K heterogeneous regions where agents value consumption vs. nature differently. Consumption obtained through pollution-inducing production also generates a negative externality on neighbors. We show that even with a decentralized policy we can obtain first-best efficiency by choosing a combination of pollution taxes in both re...

This paper investigates the alleged predatory behaviour in the UK quality newspaper industry in the 1990s in terms of product repositioning using a horizontal differentiation model and industry data. It supports the call for an 'effects based' approach to competition law by showing that non-price conduct can be a critical and less visible, compleme...

Forthcoming in Annals of Economics and Statistics. This paper considers collusion between asymmetric networks in the telecommunications industry. Its primary purpose is to fill the gap between the literature on collusion between asymmetric firms and the literature on collusion in the telecommunications industry. Employing the standard Hotelling fra...
Article
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 and Gabszewicz et al., 2002 who show that advertising financing can lead to minimu...
Article
This paper investigates the effect of spillovers in a model of endogenous technical change resulting from network effects as can be, for example, found in the market for hand‐held video consoles on the existence of a lower bound to market concentration.
Article
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 Areeda-Turner Rule has become the standard to assess c...

Article
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 location to another. For a fixed planning horizon we in...
Article
This paper investigates the price war in the UK quality newspaper industry in the 1990s. We build a model of the newspaper market which encompasses demand for differentiated products on both, the readers and advertisers side of the market, and profit maximization by four competing oligopolistic editors who recognize the existence of an indirect net...
Article
This paper investigates the effects of entry on welfare in the Telecommunications industry. Equilibrium pricing parameters for monopoly and duopoly situations are determined where access charges are chosen non-cooperatively. Welfare comparisons between alternative access pricing regimes are also performed.
Article
Full-text available
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 choices that are above the efficient level.
Article
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. What distinguishes the public good investigated in this analysis is its direct provision technology which is commonplace in modern information technologies.

This paper provides a survey on studies that analyze the macroeconomic effects of intellectual property rights (IPR). The first part of this paper introduces different patent policy instruments and reviews their effects on R&D and economic growth. This part also discusses the distortionary effects and distributional consequences of IPR protection a...

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
Article
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 positive access charge markups which reconciles empirical o...

I study a budget-constrained, private-valuation, sealed-bid sequential auction with two incompletely-informed, risk-neutral bidders in which the valuations and income may be non-monotonic functions of a bidder's type. Multiple equilibrium symmetric bidding functions may exist that differ in allocation, efficiency and revenue. The sequence of sale a...
