We examine the effects of mobile termination rate regulation in asymmetric oligopolies. We do this by extending existing models of asymmetric duopoly and symmetric oligopoly where consumer expectations about market shares are passive. We first calibrate product differentiation parameters using...

Economic analysis of spectrum allocation policies focuses on competitive bidding for wireless licenses. Auctions generating high bids, as in Germany and the UK, are identified as successful, while those producing lower receipts, as in Switzerland and the Netherlands, are deemed fiascoes. Yet,...

We evaluate the welfare effects of the Roam-Like-At-Home regulation, which drastically re-duced the price of accessing the mobile internet for EU residents when traveling abroad in the European Economic Area. Estimates from individual-level usage data suggest that consumer surplus increased by...

Intercarrier compensation imposes large costs on consumers by increasing the prices of long-distance and wireless service and discouraging consumers from using them. Because of these hidden subsidies, local phone rates are below cost for residential subscribers in all but the most dense urban...

We analyze the welfare effects of parity rules, prevalent in telecommunications and other regulated industries, that force a vertically-integrated input monopolist to treat its own downstream affiliate and downstream competitors comparably in terms of input price and quality. When input pricing...

We analyze the welfare effects of “parity” rules that force a vertically-integrated input monopolist (VIM) to treat downstream affiliates and competitors alike in terms of price and quality. We find that input-quality parity can lower social welfare when input pricing is unregulated. In...
