Constrained efficiency is characterized in an asset market, subject to search frictions, where sellers are privately informed about the type of their asset. The type determines the opportunity cost of the asset for sellers and the quality of the asset for buyers. The constrained efficient...

A model of over-the-counter markets is proposed. Some asset buyers are informed in that they can identify high quality assets. Heterogeneous sellers with private information choose what type of buyers they want to trade with. When the measure of informed buyers is low, there exists a unique and...

Constrained efficient allocation (CE) is characterized in a model of adverse selection and directed search (Guerrieri, Shimer, and Wright (2010)). CE is defined to be the allocation that maximizes welfare, the ex-ante utility of all agents, subject to the frictions of the environment. When...

I study a model in which firms invest in capital and post wages, and heterogeneous workers, who have private information about their skills, choose where to apply. Workers and firms match bilaterally. Each matched agent gets an exogenous payoff from the match before wages are paid. Each of these...

The constrained efficient allocation (CE) is characterized in the model of Guerrieri, Shimer, and Wright (2010), a model of adverse selection and frictions in the directed (competitive) search theory. CE is defined to maximize the ex-ante utility of all types subject to the frictions in the...
