This paper presents results from a calibrated welfare model of the UK mobile telephony market which includes many mobile networks; calls to and from the fixed network; networkbased price discrimination; and call externalities. The analysis focuses on the short-run effects of adopting lower...

We report experimental results on exclusive dealing inspired by the literature on "naked exclusion.'' Our key findings are: First, exclusion of a more efficient entrant is a widespread phenomenon in lab markets. Second, allowing incumbents to discriminate between buyers increases exclusion rates...

We consider a vertically related industry and analyze how the total harm due to a price increase upstream is distributed over downstream firms and final consumers. For this purpose, we develop a general model without making specific assumptions regarding demand, costs, or the mode of...

This paper studies the role of structural remedies in merger control in a Cournot setting where (endogenous) mergers are motivated by prospective efficiency gains and must be submitted to an Antitrust Authority (AA) which might require partial divestiture for approval. Both positive and negative...

We introduce a flexible model of telecommunications network competition with non-uniform calling patterns, which account for the fact that customers tend to make most calls to a small subset of people. Equilibrium call prices are distorted away from marginal cost, and competitive intensity is...

We present a tractable model of competition between an arbitrary number of interconnected communications networks in the presence of tariff-mediated network externalities, call externalities, and cost and market share asymmetries. On the theory side, we provide a criterion for stability in...

Mobile phone networks' practice of charging higher prices for off-net than for on-net calls has been pinpointed as the source of two competition problems: underprovision of calls and permanent disadvantages for small networks. We consider these allegations and four different remedies: limiting...

finite call and receiving prices exist for a large and realistic range of call externality values. This allows regulation of …

This paper studies the role of the failing firm defense (FFD) concept in merger control in a Cournot setting where: (i) endogenous mergers are motivated by prospective efficiency gains; and (ii) mergers must be submitted to an Antitrust Authority which might require partial divestiture for...

existing access regulation is based on a single essential network. We show that continued asymmetric access regulation of one … network does not control sufficiently for market power and benefits the unregulated network, and that symmetric regulation … would lead to higher consumer surplus. Furthermore, the whole setup of access regulation may not be viable in the long run …
