Asymmetric information can distort market outcomes. I study how the online disclosure of information affects consumers' behavior and firms' incentives to upgrade product quality in markets where information is traditionally limited. I first build a model of consumer search with firms' endogenous...

We analyze a simple supply chain with one supplier, one retailer and uncertainty about market demand. Focusing on the incentives of the supplier and the retailer to enhance their private information about the actual market conditions, we show that choices on information acquisition are strategic...

This paper analyses the effect of firm learning on labor market efficiency in a frictional labor market with asymmetric information. I consider a model with random matching and wage bargaining a la Pissarides (1985, 2000) where worker ability is unknown to firms at the hiring stage. Firm...

The aim of this paper is to study asset reallocation in financial markets subject to search, bargaining, and information frictions, and to analyze the impact of monetary policy on equilibrium outcomes. The main results show that private information regarding the quality of an asset impairs its...

Why do people appear to forgo information by sorting into “echo chambers”? We construct a highly tractable multi-sender, multi-receiver cheap talk game in which players choose with whom to communicate. We show that segregation into small, homogeneous groups can improve everybody’s...

We study intermediaries who seek to maximize gains from trade in bilateral negotiations. Intermediaries are players: they cannot commit to act against their objective function and deny, in some cases, trade they believe to be beneficial. This impairs their ability to assist the parties relative...

I develop a dynamic version of the competitive search model with adverse selection in Guerrieri, Shimer and Wright (2010). My model allows for an analysis of the effects of firm learning on labor market efficiency in the presence of search frictions. I find that firm learning increases relative...

Announcing a large fiscal stimulus may signal the government’s pessimism about the severity of a recession to the private sector, impairing the stabilizing effects of the policy. Using a theoretical model, we show that these signaling effects occur when the stimulus exceeds expectations and...
