A standard result in bargaining with symmetric information is that agents exploit all gains from trade, and reach efficient agreements immediately. Models of delayed and inefficient agreements are typically based on asymmetric information regarding bargainer types. However, such models often...

We investigate the efficiency of dynamic random matching and bilateral bargaining markets with adverse selection. We take a detail-free approach to the bargaining game, assuming only that: (a) each agent's actions are optimal given the equilibrium market conditions and the equilibrium strategy...

We rationalize a special type of sharing information which can typically be found in markets for occupational disability insurances. There, firms share information about acceptances and rejections of an applicant. We set up a multiple-step signalling model with uninformed agents and endogenize...

We propose a parsimonious model with adverse selection where delinquency, renegotiation, and bankruptcy all occur in equilibrium as a result of a simple screening mechanism. A borrower has private information about her cost of bankruptcy, and a lender may use random contracts to screen different...

We consider the problem of optimally acquiring a position in a financial asset by submitting orders to a standard exchange and a dark pool. We assume that volatility is stochastic and trading at the standard exchange causes a price impact. Orders sent to the dark pool do not generate price...

We show that firms intermediating trade have incentives to overinvest in financial expertise, and that these investments can be destabilizing. Financial expertise in our model improves firms' ability to accurately estimate value when trading a security. It creates adverse selection, which under...

We study non-stationary dynamic decentralized markets with adverse selection in which trade is bilateral and prices are determined by bargaining. Examples include labor markets, housing markets, and markets for financial assets. We characterize equilibrium, and identify the dynamics of...

This paper studies asset markets where buyers of assets do not inherit private information from previous owners and must learn asset quality over time. Imperfect information transmission reduces asymmetric information, but also reduces the trading volume, prices and efficiency. This result is...
