“Overbidding” with respect to risk-neutral Nash predictions in first-price auction experiments has been consistently reported in the literature. One possible explanation for overbidding is that participants in these experiments do not have a clear perception of probabilities, which causes...

We show that a non-Bayesian learning procedure leads to very permissive implementation results concerning the efficient allocation of resources in a dynamic environment where impatient, privately informed agents arrive over time, and where the designer gradually learns about the distribution of...

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.

Random choices of prices and product characteristics can be used by a contestable monopolist to deter entry and fully extract the monopoly rent. We develop this idea in a model of Bertrand price competition. In equilibrium, one firm enters the market and makes choices that are unpredictable to...

According to the well-known “merger paradox”, in a Cournot market game mergers are generally unprofitable unless most firms merge. The present paper proposes an optimal merger mechanism. With this mechanism mergers are never unprofitable, more profitable than in other known mechanisms, and...

Why do some participants in online auctions place their bids right before the time of closing? Using e-Bay data, we propose count-data models to look at both the presence of the late-bidding phenomenon and its intensity. Our results reveal significant differences between extremely late-bidders...

A monopoly that sells to brand-name loyal customers and to price-sensitive customers must decide whether to carry both name-brand and private-label products and how much to charge. The monopoly may charge either more or less for the brand name if it carries a private label, and the price...

I investigate an asymmetric duopoly where a public enterprise must supply the demand it faces, while a private enterprise has no such obligation. I show that such an asymmetric regulation yields the first-best outcome (Walrasian equilibrium).

This paper quantifies the effects of drug monopolies and low per-capita income on pharmaceutical prices in developing economies using the example of the antiretroviral drugs (ARVs) used to treat HIV.

We examine and compare the (normally, mixed) symmetric equilibrium bidding strategies in first-price and all-pay common value multiple item auctions with a random number of bidders, who only seek one of the identical items and have the same budget.
