Neeman (2004) and Heifetz and Neeman (2006) have shown that, in auctions with incomplete information about payoffs, full surplus extraction is only possible if agents’ beliefs about other agents are fully informative about their own payoff parameters. They argue that the set of...

Governments must usually take policy decisions with an imperfect knowledge of the economic actors' type or the actors' effort level. These issues are addressed within the framework of classic adverse selection or moral hazard models. I discuss in this paper how would the government’s and the...

A mediator, with no prior information and no control over the market protocol, attempts to redesign the information structure in the market by running an information intermediation mechanism with transfers that first elicits information from an agent, and then discloses information to another...

This paper studies mechanism design with limited commitment where agents have persistent correlated types over the infinite horizon. The mechanism designer now faces the informed-principal problem in addition to usual issues with i.i.d. types. With an infinite horizon and nondurable good, there...

In many trade environments - such as online markets - buyers fully learn their valuation for goods only after contracting. I characterize the buyer-optimal ex-ante information in such environments. Employing a classical sequential screening framework, I find that buyers prefer to remain...

This paper studies the revelation principle for mechanisms with limited commitment when agents have correlated persistent types over the infinite horizon. After characterizing necessary and sufficient conditions to construct a mechanism with same ex-ante payoffs and interim beliefs to all...

The endowment and attachment effect are empirically well-documented in bilateral trade situations. Yet, the theoretical literature has so far failed to formally identify these effects. We ftll this gap by introducing expectations-based loss aversion, which can explain both effects, into the...
