A network market is a market in which the benefit each consumer derives from a good is an increasing function of the number of consumers who own the same or similar goods. A major obstacle that plagues the introduction of a network good is the ability to reach critical mass, namely, the minimum...

In this paper we present the results of an experiment aimed at testing the ability of consumers to coordinate actions in a market in which network externalities are present. Such markets are characterized by the necessity for consumers to believe that a certain minimum number of people will buy...

In this paper we analyze a network market in which it is beneficial for a producer to invite competitors to share a market, even when this is not needed in order to affect consumer beliefs. Because of the nature of such goods, the demand curve for network markets typically rises and then falls....

Television is the dominant entertainment medium for hundreds of millions. This chapter surveys the economic forces that determine the production and consumption of this content. It presents recent trends in television and online video markets, both in the US and internationally, and describes...

We study targeted information in a duopoly model with differentiated products, allowing for consumers with limited attention. The presence of inattentive consumers incentivizes firms to behave as if they were mass-advertisers, despite their ability to direct their messages precisely towards...

This paper develops a framework to systematically study how changes in market conditions affect the equilibrium inequality between heterogeneous agents. By stating our setting as a "competition for market shares", we can derive inequality predictions for vastly different competition models. This...

The last decades have seen large improvements in digital advertising technology that allowed firms to better target specific consumer tastes. This research studies the relationship among digital advertising, the rise of varieties, and economic welfare. We develop a model of advertising and...

We examine the implications of limited consumer attention for the targeting decisions of competing firms. Limited attention alters the strategic role of information provision as firms may become incentivized to behave as mass advertisers, despite perfect targeting abilities. We analyze the...

We propose a model of competitive attention based on two key premises: i) People have limited information processing capacities and ii) consideration sets are formed according to relative salience. The equilibrium predictions we obtain can help to understand, and connect, diverse empirical...

Despite the empirical relevance of advertising strategies in concentrated markets, the economics literature is largely silent on the effect of persuasive advertising strategies on pricing and market structure and increasing (or decreasing) dominance. We propose a simple model of persuasive...
