I investigate how an incumbent firm deters entry by crowding the market, even when the incumbent can withdraw its stores in response to entry. In a two-location model, Judd (1985) shows such spatial entry deterrence is not credible. In contrast, I demonstrate spatial preemption can be credibly...

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.

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 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...

In screening with non-concave costs: (i) cycles of active IC constraints can make all packages distorted; (ii) standard screening can be less profitable than price discrimination within a consumer type using first-come-first-served rationing.

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.

In infinite horizon, a credible durable-good monopolist may resort to intertemporal price discrimination. We provide an analytical characterization of his optimal price policy when consumers and the monopolist have different values for the trade because of distinct discount factors.

Many economists are aware that the conditions for the efficiency and monopolization in a partial equilibrium framework are the extremes of the Ramsey–Boiteux formula when the Lagrange multiplier for the budget varies. We formalize the duality existing between the welfarist and monopolist...

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...
