In this paper we build a formal model to study market environments where information is costly to acquire and is of use also to potential competitors. In such situations a market for information may form, where reports - of unverifiable quality - over the information acquired are sold. A...

We study a general static noisy rational expectations model, where investors have private information about asset payoffs, with common and private components, and about their own exposure to an aggregate risk factor, and derive conditions for existence and uniqueness (or multiplicity) of...

We examine settings - such as litigation, labor relations, or arming and war - in which players first make non-contractible up-front investments to improve their bargaining position and gain advantage for possible future conflict. Bargaining is efficient ex post, but we show that a player may...

We analyze vertical product differentiation in a model where a good's quality is unobservable to buyers before purchase, a continuum of quality levels is technologically feasible, and minimum quality is supplied under competitive conditions. After purchase the true quality of the good is...

We analyze how the introduction of the voting advice application (VAA) smartvote affects voter turnout, voting behavior and electoral outcomes. The Swiss context offers an ideal setting to identify the causal effects of online information with aggregate real world data because smartvote was...

In Spence's (1973) signaling by education model and in many of its extensions, firms can only infer workers' productivities from their education choices. In reality, firms also use sophisticated pre-employment auditing to learn workers' productivities. We characterize the trade-offs between...

We examine whether the desire for more information is people's dominant motive for reading economic and political news. Drawing on representative samples of the U.S. population with more than 15,000 respondents in total, we measure and experimentally vary people's beliefs about the...

We investigate the strategies of a data intermediary selling consumer information to firms for price discrimination purpose. We analyze how the mechanism through which the data intermediary sells information influences how much consumer information she will collect and sell to firms, and how...
