This paper examines the relationship between misinformation about product quality and quality standards, such as minimum quality standards (MQSs) and certification criteria, when products are vertically differentiated in terms of their health/safety aspects. We investigate the welfare effect of...

We characterize the product line choice and pricing of a monopolist as the upper envelope of net marginal revenue curves to the individual product demand functions. The equilibrium product varieties to include in a product line are those yielding the highest upper envelope. In a central case...

Two forces have reshaped global securities markets in the last decade: Exchanges operate at much faster speeds and the trading landscape has become more fragmented. In order to analyze the positive and normative implications of these evolutions, we study a framework that captures (i) exchanges'...

This paper describes open research questions related to the competition and market structure of financial exchanges and argues that only a combination of industrial organization and finance can satisfactorily attack these questions. Two examples are discussed to illustrate how the combination of...

Cooperatives are of particular interest to economists because of their unique ownership structure and the incentives this structure creates. In addition to the so-called property rights problems (e.g., free-rider, horizon, and portfolio problems), the analysis of agricultural cooperatives has...

This paper develops a duopoly model of vertical product differentiation where two domestic firms incur variable costs of quality development. These domestic firms can purchase a superior foreign technology through licensing. Outcomes between Bertrand and Cournot competition are compared. We find...

In this paper, I examine a quality-then-price game in a fully covered market where firms are uncertain about consumer tastes regarding quality. The equilibrium is characterized under the fixed costs and variable costs of quality improvement, respectively. It is shown that the uncertainty is a...

In markets where product quality is important, more than one characteristic is usually necessary for producers to define product quality. Standard theory maintains that: (i) in a duopoly there will be a quality leader no matter whether the product can incorporate one or two vertical attributes;...
