We examine the design of nonlinear prices by a multiproduct monopolist who serves customers with multidimensional but correlated types. We show that the monopoly can exploit the correlations between consumers' types to design pricing mechanisms that fully extract the surplus from each consumer....

Electronic commerce and flexible manufacturing allow personalization of initially standardized products at low cost. Will customers provide the information necessary for personalization? Assuming that a consumer can control the amount of information revealed, we analyze how his decision...

When a durable good of uncertain quality is introduced to the market, some consumers strategically delay their buying to the next period with the hope of learning the unknown quality. We analyze the monopolist's pricing strategies when consumers have strategic delay incentives. We show when the...

Carrying multiple brands and holding periodic sales are two common marketing strategies for sellers with market power. One puzzle is that sellers often employ diverse strategies in terms of using these two tools. This paper offers an explanation to this puzzle by providing a simple framework to...

Entry into a network industry is modeled, focusing on consumers' expectations formation. Equilibrium expectations are endogenous and they depend on prices, acting as a coordination device among consumers. The model is able to account for aggressive pricing policies by the incumbent and by the...

I study a dynamic model of consumer privacy and platform data collection. In each period, consumers choose their level of platform activity. Greater activity generates more information about the consumer, thereby increasing platform profits. Although consumers value their privacy, the platform...

In consumer-to-consumer online platforms that enable selling (e.g., eBay, Taobao) or sharing (e.g., Airbnb, Uber) of goods and services, information asymmetry between providers (e.g., sellers, hosts, drivers) and consumers (e.g., buyers, guests, passengers) pose challenges. Such platforms...

Revisions incorporated into the Horizontal Merger Guidelines in 2010 claim that the Department of Justice and the Federal Trade Commission consider anticompetitive effects to product “variety” when evaluating mergers. The Guidelines do not, however, explain the methodology or tools that can...

We study optimal pricing in the presence of recommender systems. A recommender system affects the market in two ways: (i) it creates value by reducing product uncertainty for the customers and hence (ii) its recommendations can be offered as add-ons which generate informational externalities....

This paper presents a model of second-degree price discrimination by a monopolistic seller who offers a menu of price-quantity pair contracts to consumers located in a social network. Network effects are local as consumers' private valuations are increasing in their friends' adoption decisions....
