We study when equilibrium prices can aggregate information in an auction market with a large population of traders. Our main result identifies a property of information—the betweenness property that is both necessary and sufficient for information aggregation. The characterization provides...

This paper analyzes a two-player all-pay auction with incomplete information. More precisely, one bidder is uncertain about the size of the initial advantage of his rival modeled as a head start in the auction. I derive the unique Bayesian Nash equilibrium outcome for a large class of cumulative...

We analyze a model of competition in Bayesian persuasion in which two senders vie for the patronage of a receiver by disclosing information about the qualities of their respective proposals, which are positively correlated. The information externality -- that the news disclosed by one sender...

We study monopoly and duopoly pricing in a two-sided market with dispersed information about users' preferences. We first show how the dispersion of information introduces idiosyncratic uncertainty about participation rates and how the latter shapes the elasticity of the demands and thereby the...

We analyze an oligopolistic competition with differentiated products and qualities. The quality of a product is not known to consumers. Each firm can make an imperfect disclosure of its product quality before engaging in price-signaling competition. There are two regimes for separating...

I study optimal information provision by a search goods seller. While the seller controls a consumer's pre-search information, which decides whether she will engage in costly search for the product, he cannot control her post-search information because the consumer would inevitably learn the...

A characteristic of many information markets is that consumers can cross-check information, i.e. observe several information sources. To explore this we build a model of market for information where information outlets can only report a coarse signal and face a distribution of consumers with...
