A vertically separated duopolistic market is analyzed in which manufacturers compete in wholesale price schedules and retailers in quantity. Under certainty there exists a continuum of equilibria. The introduction of an uncertain demand parameter, observed only by retailers, dramatically reduces...

We show that the Coase conjecture does not hold when a durable-goods monopolist also sells nondurable goods that are demand related to the durable. The presence of nondurable complements or substitutes reduces the rate at which the monopolist introduces the durable into the market. The price of...

Consider a duopoly market in which consumers have heterogeneous information about the quality differential q of the two goods. When firms are ignorant about q, consumers rationally believe that a firm with high market shares is likely to produce a high-quality good. As a result, firms try to...

This article analyzes the duality of prices and quantities in a differentiated duopoly. It is shown that if firms can only make two types of binding contracts with consumers, the price contract and the quantity contract, it is a dominant strategy for each firm to choose the quantity (price)...

When analyzing a Cournot market with strictly convex costs dependent on a private information parameter, do we err more by ignoring market power or by ignoring the impact of incomplete information? Is the welfare loss at the market outcome driven by private information or by market power? The...

We analyze the effects of strategic behavior by a large informed trader in a price discovery process used in opening auctions in continuous trading systems. It is found that the large informed trader manipulates the market using a contrarian strategy to neutralize the effect of the trades of...

In this article I propose a monopolistic competition framework to analyze the effects of different disclosure rules used by trade associations on the incentives to share information and on the welfare of consumers, firms, and society. This framework is appropriate whenever a single firm cannot...
