In the dominant firm-competitive fringe model, where firms purchase input from a common supplier via two-part tariff contracts, we demonstrate that countervailing power may be neutral. Unlike Chen (2003), more countervailing power may not lead to lower consumer prices.

We analyze dynamic monopoly pricing under consumption externalities, focusing on pricing under negative externalities. We also attempt to generalize models in the previous literature, which encompass both negative and positive externalities, by incorporating a consumer’s discount factor for...

This paper shows in a vertical product differentiation model with variable costs of quality that monopolistic third-degree price discrimination always reduces welfare regardless of whether the quality is fixed or is endogenous. The results provide rich implications for antitrust policy.

We examine an entry-deterrence model in the commons. We investigate in which contexts asymmetric information among firms becomes welfare improving, and in which settings an uninformed regulator may prefer to assess and disseminate information about the available stock among firms.

We study the welfare effects of parallel trade (PT) considering investment in quality. We thus revisit the case for PT in research-intensive industries. We find that PT may raise quality, depending on how preferences for quality differ across countries. Conditional on quality, consumer surplus...

This letter addresses the second-degree price discrimination issue when a monopolized product is tied with environmental quality. The monopolist may degrade environmental quality too much when marginal valuations of environmental quality and the good itself are positively related across consumers.

A test of the predictions of Dana’s (2001) model of monopoly price dispersion under demand uncertainty using ticket price data from Major League Baseball shows that ticket price dispersion changes systematically with demand uncertainty, verifying the predictions of the model.

We show that the price-setting subgame in the classic Hotelling’s model (1929) with the linear transport costs has the unique equilibrium solution for all location pairs under the assumption that duopolists secure themselves against being driven out of the market by undercutting. In contrast...

We examine the impact of (and links between) two types of economic integration on the stability of multimarket collusion when firms interact in quantities in segmented markets: (1) multilateral trade liberalization, captured by a reduction of trade costs across all markets; and (2) preferential...

Advertising and price have been shown to signal product quality. Most works limit the number of types to high and low quality. I characterize the optimal separating marketing strategy when both quality and marginal cost are uncertain and continuous variables.
