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 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...

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 …

How does an upstream firm determine the size of its distribution network, and what is the role of vertical restraints? To address these questions we develop and estimate two models of outlet entry, starting from the basic trade-off between market expansion and fixed costs. In the coordinated...
