Universal service objectives are pervasive in telecommunications, and have gained new relevance after liberalization and the introduction of competition in many markets. Despite their policy relevance, little work has been done allowing for a thorough discussion of instruments designed to...

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 consider a media market where consumers mix content offered by different firms and firms charge two-part tariffs. As compared to pure linear pricing (pay-per-view), firms make higher profits, while consumers are worse off and the allocation is not first-best. We also consider flat...

We consider a market where consumers mix content offered by different firms. We show how tariff structures have an impact on firms' profits and efficiency. As compared to pure linear pricing, when firms charge two-part tariffs they make higher profits, while consumers are worse off and the...

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 set of contacts. Equilibrium call prices are distorted away from marginal cost, and competitive intensity is...

We analyze the impact of mandatory access on the infrastructure investments of two competing communications networks, and show that for low (high) access charges firms wait (preempt each other). Contrary to previous results, under preemption a higher access charge can delay first investment....

We analyze competition between vertically integrated infrastructure operators that provide access in different geographical areas. A regulator may impose a uniform access price, set local access rates, or deregulate access locally. We analyze the impact of these alternative regulatory regimes on...

Often, fixed-line incumbents also own the largest mobile network. We consider the effect of this joint ownership on market outcomes. Our model predicts that while fixed-to-mobile call prices to the integrated mobile network are more efficient than under separation, those to rival mobile networks...

We show that the prediction of a strategic connectivity breakdown under a receiving-party-pays (RPP) system and discrimination between on- and off-net prices does not hold up once more than two networks are considered. Indeed, equilibria with finite call and receiving prices exist for a large...
