This paper considers the screening problem faced by a monopolist of a network good in a general setting. We demonstrate that the joint presence of asymmetric information and network externalities revise the "no distortion on the top" and "one-way distortion" principle. The pattern of consumption...

In the paper, the fundamental question is under what conditions loyalty discounts and rebates adopted by a dominant firm cause anti-competitive effects. Fidelity schemes, although extremely frequent in the market, if applied by a dominant firm, are likely to be judged as illegal per se, as...

In nonlinear pricing environment with correlated types, we characterize optimal selling mechanisms when buyers could form a coalition to coordinate their reports and to arbitrage on the goods. We find that when the types of agents are weakly positively correlated, the optimal weakly...

This paper considers an entry-deterring nonlinear pricing problem faced by an incumbent firm of a network good. The analysis recognizes that the installed user base/network of incumbent monopolist has preemptive power in deterring entry if the entrant’s good is incompatible with the...

We examine the impact of multiproduct nonlinear pricing on profit, consumer surplus and welfare in a duopoly. When consumers buy all their products from one firm (the one-stop shopping model), nonlinear pricing leads to higher profit and welfare, but often lower consumer surplus, than linear...

Standard stochastic frontier models estimate log-linear specifications of production technology, represented mostly by production, cost, profit, revenue, and distance frontiers. We develop a methodology for stochastic frontier models of count data allowing for technological and inefficiency...
