In industries where consumers can assemble their own systems, firms must decide whether to make their components compatible with those of their rivals. We examine a two-stage game in which two fully integrated firms make their compatibility decisions before competing in prices. The symmetric...

Innovators who have made significant breakthroughs may be tempted to get a head start in developing the applications of a new discovery before commercializing any new product. We consider how this socially undesirable waiting period and the pattern of development of subsequent innovations are...

In this article, we analyze the pricing strategies of firms that compete for the demand of an assortment of goods in a complete information static framework. In particular, we model the competition between two symmetric firms in a market that consists of two types of consumers, each of which may...

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)...

This article provides a systematic analysis of the welfare effects of vertical integration by a monopolist input supplier into a monopolistically competitive downstream industry. We give sufficient conditions on consumer preferences that lead to Pareto-improving vertical integration and...

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...
