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.

Determining the social cost of carbon emissions (SCC) is a crucial step in the economic analysis of climate change policy as the US government’s recent decision to use a range of estimates of the SCC centered at $77/tC (or, equivalently, $21/tCO2) in cost-benefit analyses of proposed...

We use micro level retail price data from convenience stores to study the link between 0-ending price points and price rigidity during a period of a runaway inflation, when the annual inflation rate was in the range of 60%–430%. Surprisingly, we find that more round prices are less likely to...

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...

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.

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.

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...

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...

Existing hedonic methods cannot be easily adapted to estimate willingness to pay for product characteristics when willingness to pay depends on a very large basket of goods. We show how to marry these methods with revealed preference arguments to estimate bounds on willingness to pay using data...
