In markets with imperfect information and heterogeneity, the information technology affects the rate at which agents meet, which in turn affects the distribution of production technologies across firms. We show that in models for such markets there are typically multiple equilibria because...

This Paper studies the consequences of price discrimination in a market for experts’ services. In the case of experts markets, where the expert observes the intervention that a consumer needs to fix his problem and also provides a treatment, price discrimination proceeds along the dimension of...

A quality improvement often necessitates modifications of varietal product features. This paper studies firms’ incentives to provide quality when this decision affects the goods’ degree of horizontal differentiation. Intuitively, one is inclined to argue that private incentives to provide...

This paper studies how the existence of a potential entrant influences an incumbent’s choice of quality in a model of vertical product differentiation and entry. Both firms face fixed set-up costs and quality-dependent costs of production, and compete on quality and price. With identical...

We examine a linear city duopoly where firms choose their locations to maximize expected profits, uncertain about how consumers will assess the relative quality of their products. Equilibrium locations depend on the ratio of the expected quality superiority to the strength of horizontal...

We study the relation between product quality and worker quality using an economic model that, under certain conditions, provides a direct link between product price, product quality and work-force quality. Our measures of product quality are the evolution in the detailed product price relative...

We analyse the impact of increased outside opportunities brought to consumers by access to a global market on local market performance under monopoly versus oligopoly. If consumers have to choose once where to shop we show that under all forms of organizing the local market, increased...

Empirical models of differentiated product demand are widely used by both academics and practitioners. While these methods treat carefully the potential endogeneity of price, until recently they have assumed the number and characteristics of the products offered by firms are exogenous. This...

We extend the persuasion game to bring it squarely into the economics of advertising. We model advertising as exciting consumer interest into learning more about the product, and determine a firm's equilibrium choice of advertising content over quality information, price information, and...

In industries with network effects, incumbents’ installed bases create barriers to entry that discourage entrepreneurs from developing new innovations. Yet, entry is not the only commercialization route for entrepreneurs. We show that the option of selling to an incumbent increases innovation...
