The paper studies the impact of homophily on the optimal strategies of a monopolist, whose marketing campaign of new product relies on a word of mouth communication. Homophily is a tendency of people to interact more with those who are similar to them. In the model there are two types of...

This paper presents a model in which price setting firms decide what to pay attention to, subject to a constraint on information flow. When diosyncratic conditions are more variable or more important than aggregate conditions, firms pay more attention to idiosyncratic conditions than to...

In many markets, sellers advertise their good with an asking price. This is a price at which the seller is willing to take his good off the market and trade immediately, though it is understood that a buyer can submit an offer below the asking price and that this offer may be accepted if the...

We present a diagrammatic and step-by-step analysis of price signaling quality. Because quality is a continuum on the real positive line, out-of-equilibrium beliefs need not be specified, i.e., every positive price is a positive outcome in equilibrium. We first study the behavior of the monopoly...

A monopolist uses prices as an instrument to influence consumers' belief about the unknown quality of its product. Consumers observe prices and sales in earlier periods to learn about the product. Every period they decide whether to consume the product or to wait for a lower price in future. We...

Manufacturers frequently post non-binding public price recommendations, but neither the rationale for this practice nor its impact on prices is well understood. I develop a model in which recommendations signal a manufacturer's production cost to searching consumers, who then form beliefs about...

In product markets, there exists substantial dispersion in prices for transactions of physically identical goods, and incumbent sellers sell at higher prices than entrants. This study develops a theory of dynamic pricing that explains these facts as results from the same fundamental friction:...
