I study costly information acquisition in a two-sided matching problem, such as matching applicants to schools. Applicant's utility is a sum of common and idiosyncratic components. The idiosyncratic component is unknown to applicants but can be learned at a cost. When applicants are assigned...

This article develops an agent-based model of security market pricing process, capable to capture main stylised facts. It features collective market pricing mechanisms based upon evolving heterogeneous expectations that incorporate signals of security issuer fundamental performance over time....

Can mechanism design save democracy? We propose a simple design that offers a chance: individuals pay for as many votes as they wish using a number of "voice credits" quadratic in the votes they buy. Only quadratic cost induces marginal costs linear in votes purchased and thus welfare optimality...

In view of some recent empirical evidence, I suggest a relationship between the magnitude of search costs and the severity of adverse selection in the context of a dynamic model with asymmetric information. In markets with small search costs sellers with low quality products misrepresent their...

Negotiation involves determining not only an agreement's price, but also its content, which typically has many aspects. We model such negotiations and provide conditions under which negotiation leads to efficient outcomes, even in the face of substantial asymmetric information regarding the...

We derive the optimal selling mechanism for a monopolist who is privately informed about the attributes of a horizontally differentiated good. To do so, we set up an informed principal problem in a Hotelling model where the buyer's preferences are described in terms of a base consumption value...

We study efficient auction design for a single indivisible object when bidders have interdependent values and non-quasilinear preferences. Instead of quasilinearity, we assume only that bidders have positive wealth effects. Our setting nests cases where bidders are ex ante asymmetric, face...

We compare equilibrium bidding in uniform-price and discriminatory auctions when a single large bidder (i.e., with multi-unit demand) competes against many small bidders, each with single-unit demands. We show that the large bidder prefers the discriminatory auction over the uniform-price...

We propose a simple and practical "raffle" mechanism for allocating a limited supply of heterogeneous goods among unit demand consumers. While the mechanism is inspired by the common "tricky tray" raffle and a housing allocation system in Singapore, it has not been analyzed before, perhaps...
