Information plays a crucial role in mechanism design problems. A potential complication is that buyers may be inattentive, and so their information may endogenously and flexibly depend on the offered mechanism. I show that it is without loss of generality to consider contour mechanisms, which...

This paper proposes a framework for demand estimation with data on bids, bidders' identities, and auction covariates from a sequence of eBay auctions. First the aspect of bidding in a marketplace environment is developed. Form the simple dynamic auction model with IPV and private bidding costs...

We propose a model of data provision and data pricing. A single data provider controls a large database that contains information about the match value between individual consumers and individual firms (advertisers). Advertisers seek to tailor their spending to the individual match value. The...

We analyze data pricing and targeted advertising. Advertisers seek to tailor their spending to the value of each consumer. A monopolistic data provider sells cookies -- informative signals about individual consumers' preferences. We characterize the set of consumers targeted by the advertisers...

We develop a model of data pricing and targeted advertising. A monopolistic data provider determines the price to access "cookies," i.e., informative signals about individual consumers' preferences. The demand for information is generated by advertisers who seek to tailor their spending to the...

Price dispersion in simultaneous online auctions is a puzzle in light of the relatively low search costs required to find the lower price. Much of this price dispersion appears to be due to lack of switching by bidders between auctions, which in turn could be due to inertia related to search...

The “law of one price” states that if prices for the same or highly similar goods vary across geographic locations by more than the cost of transport, then traders will shift supply and demand to exploit the price differences. However, several frictions prevent traders from doing this,...

This paper studies the problem of information provision in auctions. The linkage principle indicates that credibly revealing private information would benefit the seller, which implies that a seller should prefer a public reserve price to a secret one if the reserve price could reveal her...

We study the revenue-maximizing mechanism when a buyer’s value evolves endogenously because of learning-by-consuming. A seller sells one unit of a divisible good, while the buyer relies on his private, rough valuation to choose his first-stage consumption level. Consuming more leads to a more...
