Consider the sale of mortgages by a loan originator to a buyer. As widely noted, such a transaction is subject to a severe adverse selection problem: the originator has a natural information advantage and will attempt to sell only the worst mortgages. However, a second important feature of this...

When contracts are unobserved, agents may have the incentive to promise the same asset to multiple counterparties and subsequently default. The author constructs an optimal mechanism that induces agents to reveal all their trades voluntarily. The mechanism allows agents to report every contract...

The authors study trade between a buyer and a seller when both may have existing inventories of assets similar to those being traded. They analyze how these inventories affect trade, information dissemination, and price formation. The authors show that when the buyer's and seller's initial...

This paper supersedes Working Paper No. 12-8. We study trade between an informed seller and an uninformed buyer who have existing inventories of assets similar to those being traded. We show that these inventories may lead to prices that increase even absent changes in fundamentals (a .run-up.),...

Superseded by Working Paper 15-10.<p> We study an optimal disclosure policy of a regulator who has information about banks’ ability to overcome future liquidity shocks. We focus on the following trade-off: Disclosing some information may be necessary to prevent a market breakdown, but disclosing...</p>

This paper is superseded by Working Paper No. 13-14. We study trade between a buyer and a seller who have existing inventories of assets similar to those being traded. We analyze how these inventories affect trade, information dissemination, and prices. We show that when traders’ initial...

When contracts are unobserved, agents may have the incentive to promise the same asset to multiple counterparties and subsequently default. The author constructs an optimal mechanism that induces agents to reveal all their trades voluntarily. The mechanism allows agents to report every contract...

Liquid markets where agents have limited capacity to sign exclusive contracts may permit agents to promise the same asset to multiple counterparties and subsequently default. I show that in such markets an exchange can arise as an intermediary whose only role is to set limits on the number of...

This paper addresses large markets where agents cannot commit to sign exclusive contracts may induce agents to promise the same asset to multiple counterparties and subsequently default. Is how that in such markets an intermediary can increase welfare by simply setting limits on the number of...
