We examine the interplay of imperfect competition and incomplete information in the context of price competition among firms producing horizontally- and vertically-differentiated substitute products. We find that incomplete information about vertical quality (e.g., consumer satisfaction) that is...

Cournot's 1838 model of strategic interaction between competing firms has become the primary workhorse for the analysis of imperfect competition, and shows up in a variety of fields, notably industrial organization and international trade. This entry begins with a tour of the basic Cournot model...

In this paper we examine the nexus between product markets and the legal system. We examine a model wherein oligopolists produce differentiated products that also have a safety attribute. Consumption of these products may lead to harm (to consumers and/or third parties), lawsuits, and...

The paper considers an oligopolistic industry in which pollution is a by-product of production. Firms are assumed to have emission permits that restrict the amount that they pollute. These permits are assumed to be tradeable and the paper discusses a structure in which the same set of firms...

In the strategic investment under uncertainty literature the trade off between the value of waiting known from single decision maker models and the incentive to preempt competitors is mainly studied in duopoly models.This paper aims at studying competitive investments in new markets where more...

We show that an environmental regulation such as a tax on pollution can act as a collusive device and induce stable cartelization in an oligopolistic polluting industry. We consider a dynamic game where pollution is allowed to accumulate into a stock over time and a cartel that includes all the...
