This paper studies the role of exchange policies as a price discrimination device in a sequential screening model with heterogeneous goods. In the first period, agents are uncertain about their ordinal preferences over a set of horizontally differentiated goods, but have private information...

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....

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...

Consumer reviews may have perverse effects, including delays of adoption in new products of unknown quality when consumers are boundedly rational. When consumers fail to take into account that past reviewers self-select to purchases, a monopolist may manipulate the posterior beliefs of consumers...

I study the welfare and price implications of consumer privacy. A consumer discloses information to a multi-product seller, which learns about his preferences, sets prices, and makes product recommendations. Although the consumer benefits from accurate recommendations, the seller may use the...

Rapid technological developments in online markets fundamentally change the relationship between consumers and sellers. Online platforms can now easily gather data about the consumer and his search behavior, that allow for price discrimination. Therefore the consumers' product search becomes a...

An auctioneer faces a pool of potential bidders that changes over time. She can delay the auction at a cost, in the hopes of having a thicker market later on. We identify a property of the distribution of bidder values—its “price elasticity”—that governs the distortions caused by revenue...

Consumer surplus in a market is affected by how the market is segmented. We study the maximum consumer surplus across all possible segmentations of a given market served by a multi product monopolist. We characterize markets for which the maximum consumer surplus equals a first best benchmark...

A data broker sells market segmentations created by consumer data to a producer with private production cost who sells a product to a unit mass of consumers with heterogeneous values. In this setting, I completely characterize the revenue-maximizing mechanisms for the data broker. In particular,...

I study a model that looks at causes, characteristics and consequences of loyalty schemes in a market with consumers who suffer from self-control problems (Gul and Pesendorfer, 2001). While the literature has mostly focused on loyalty schemes as tools used by firms to compete (Caminal and...
