We analyze oligopolistic third-degree price discrimination relative to uniform pricing, when markets are always covered. Pricing equilibria are critically determined by supply-side features such as the number of firms and their marginal cost differences. It follows that each firm's Lerner index...

In a recent paper, Alipranti et al. (2014, Price vs. quantity competition in a vertically related market, Economics Letters, 124: 122-126) show that in a vertically related market Cournot competition yields higher social welfare compared to Bertrand competition if the upstream firm subsidises...

We investigate the welfare effects of third-degree price discrimination by a two-sided platform that enables interaction between buyers and sellers. Sellers are heterogenous with respect to their per-interaction benefit, and, under price discrimination, the platform can condition its fee on...

This paper analyzes price discrimination of an upstream cartel in the presence of a dominant firm at the retail level. Charging different wholesale prices creates a bond between the upstream cartel and the favored downstream firm. This bond reduces or eliminates this firm's incentives to accept...
