Systemic risk arises when shocks lead to states where a disruption in financial intermediation adversely affects the economy and feeds back into further disrupting financial intermediation. We present a macroeconomic model with a financial intermediary sector subject to an equity capital...

We present a model to study the dynamics of risk premia during crises in asset markets where the marginal investor is a financial intermediary. Intermediaries face a constraint on raising equity capital. When the constraint binds, so that intermediaries' equity capital is scarce, risk premia...

We develop a model in which the capital of the intermediary sector plays a critical role in determining asset prices. The model is cast within a dynamic general equilibrium economy, and the role for intermediation is derived endogenously based on optimal contracting considerations. Low...

We measure how securitized assets, including mortgage-backed securities and other asset-backed securities, have shifted across financial institutions over this crisis and how the availability of financing has accommodated such shifts. Sectors dependent on repo financing - in particular, the...

We develop a structural credit risk model to examine how the interactions of liquidity and default risk affect corporate bond pricing. By explicitly modeling debt rollover and by endogenizing the holding costs via collateralized financing, our model generates rich links between liquidity risk...

We develop a dynamic model of trading and investment with limited aggregate resources to study investment cycles. Unverifiable idiosyncratic investment opportunities imply market prices to play a role of rent distribution, distorting private investment incentives from a social point of view....

Debt maturity influences debt overhang: the reduced incentive for highly- levered borrowers to make real investments because some value accrues to debt. Reducing maturity can increase or decrease overhang even when shorter-term debt's value depends less on firm value. Future overhang is more...

We study information acquisition and dynamic withdrawal decisions when a spreading rumor exposes a solvent bank to a run. Uncertainty about the bank's liquidity and potential failure motivates depositors who hear the rumor to acquire additional noisy signals. Depositors with less informative...

This paper models a firm's rollover risk generated by conflict of interest between debt and equity holders. When the firm faces losses in rolling over its maturing debt, its equity holders are willing to absorb the losses only if the option value of keeping the firm alive justifies the cost of...

We develop a dynamic model of debt runs on a firm, which invests in an illiquid asset by rolling over staggered short-term debt contracts. We derive a unique threshold equilibrium, in which creditors coordinate their asynchronous rollover decisions based on the firm's publicly observable and...
