Non-exclusive contracts, collateralized trade, and a theory of an exchange
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 contracts that agents can report voluntarily. In some cases, these limits must be non-binding in equilibrium, and reported trades must not be made public. A (costly) alternative to an exchange is collateralized trade, and the gains from an exchange increase when agents have more intangible capital (e.g., ...

Market run-ups, market freezes, inventories, and leverage
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.), but may also make trade impossible (a .freeze.) and hamper information dissemination. Competition may amplify the run-up by inducing buyers to enter loss-making trades at high prices to prevent a competitor from purchasing at a lower price and releasing bad news about inventory values. Inventories ...

Stress Tests and Information Disclosure
We study an optimal disclosure policy of a regulator that has information about banks (e.g., from conducting stress tests). In our model, disclosure can destroy risk-sharing opportunities for banks (the Hirshleifer effect). Yet, in some cases, some level of disclosure is necessary for risk sharing to occur. We provide conditions under which optimal disclosure takes a simple form (e.g., full disclosure, no disclosure, or a cutoff rule). We also show that, in some cases, optimal disclosure takes a more complicated form (e.g., multiple cutoffs or nonmonotone rules), which we characterize. We ...

Contingent capital
Government bailouts during the recent financial crisis were controversial because of the burden on taxpayers and because even if taxpayers eventually get their money back, such bailouts can undermine banks? incentives not to take excessive risk in the future. New regulatory reforms aim to avoid such crises in the future. One proposal is to require banks to hold ?contingent capital.? In this article, Yaron Leitner explains what contingent capital is and discusses some of the arguments in favor of it. He also discusses potential implementation problems and looks at some of the alternatives.

Convertible securities and venture capital finance
Venture capital financing relies heavily on convertible securities; the most common type is convertible preferred stock. Venture capital contracts also specify control rights that describe who gets to make the firm's decisions. The recent literature has provided some theoretical explanations for the use of these two features. Underlying these explanations is the idea that individuals can take actions that affect the firm's performance but that these actions cannot be specified in a contract. In this article, Yaron Leitner focuses on venture capital contracts, but the ideas presented can be ...

Legal uncertainty and contractual innovation
Although innovative contracts are important for economic growth, when firms face uncertainty as to whether contracts will be enforced, they may choose not to innovate. Legal uncertainty can arise if a judge interprets the terms of a contract in a way that is antithetical to the intentions of the parties to the contract. Or sometimes a judge may understand the contract but overrule it for other reasons. How does legal uncertainty affect firms? decisions to innovate? In ?Legal Uncertainty and Contractual Innovation,? Yaron Leitner explores issues related to legal uncertainty, particularly the ...

REGULATING A MODEL
REVISED: 5/2018: We study a situation in which a regulator relies on models produced by banks in order to regulate them. A bank can generate more than one model and choose which models to reveal to the regulator. The regulator can find out the other models by monitoring the bank, but, in equilibrium, monitoring induces the bank to produce less information. We show that a high level of monitoring is desirable when the bank's private gain from producing more information is either sufficiently high or sufficiently low (e.g., when the bank has a very little or very large amount of debt). When ...

Why do markets freeze?
In normal times, investors buy and sell financial assets because there are gains from trade. However, markets do not always function properly ? they sometimes ?freeze.? An example is the collapse of trading in mortgage-backed securities during the recent financial crisis. Why does trade break down despite the potential gains from trade? Can the government intervene to restore the normal functioning of markets? In ?Why Do Markets Freeze?,? Yaron Leitner explains what a market freeze is and some of the theories as to why these freezes occur.

Market run-ups, market freezes, and leverage
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 leverage is moderate, inventories increase price and trade volume, but when leverage is high, trade may become impossible (a "market freeze"). Their analysis predicts a pattern of trade in which prices and trade volume first increase, and then markets break down. The authors use their model to discuss ...

Should regulators reveal information about banks?
Regulators collect and produce information about banks. This information helps regulators monitor the safety and soundness of the banking system, and it also helps policymakers preserve financial stability. A key issue is whether this information should be made public and, if so, to what extent. In this article, we will explore some of the tradeoffs involved.
