We propose a new theory of systemic risk based on Knightian uncertainty (or "ambiguity"). We show that, due to uncertainty aversion, beliefs on future asset returns are endogenous, and bad news on one asset class induces investors to be more pessimistic about other asset classes as well. This...

We study how debt market frictions constraining the ability to replace bank with bond financing during a tightening in bank credit supply affect corporate yield spreads. We document that more inflexible firms suffer bigger increases in bond yield spreads as bank credit supply tightens. Debt...

Using a comprehensive panel data set on U.S. households, we study the effects of the 2005 Bankruptcy Abuse Prevention and Consumer Protection Act (BAPCPA), the most substantive reform of personal bankruptcy in the United States since the Bankruptcy Reform Act of 1978. The 2005 legislation...

We study the relation between information and fire sales during a crisis. We argue that the reinforcing effect of funding liquidity on market liquidity is weaker when investors have more information about the assets facing sudden price drops (Brunnermeier and Pedersen, 2009). We focus on the...

We present a network model of the interbank market in which optimizing risk averse banks lend to each other and invest in non-liquid assets. Market clearing takes place through a tâtonnement process which yields the equilibrium price, while traded quantities are determined by means of a...

We measure the consequences of asymmetric information and imperfect competition in the Italian lending market. We show that banks’ optimal price response to an increase in adverse selection varies with competition. Exploiting matched data on loans and defaults, we estimate models of demand for...

Government guarantees to financial institutions are intended to reduce the likelihood of runs and bank failures, but are also usually associated with distortions in banks’ risk taking decisions. We build a model to analyze these trade-offs based on the global-games literature and its...

Exploiting the Japanese banking crisis as a laboratory, we provide firm-level evidence on the real effects of bank bailouts. Government recapitalizations result in positive abnormal returns for the clients of recapitalized banks. After recapitalizations, banks extend larger loans to their...

We design a new, implementable capital requirement for large financial institutions (LFIs) that are too big to fail. Our mechanism mimics the operation of margin accounts. To ensure that LFIs do not default on either their deposits or their derivative contracts, we require that they maintain a...

Do religious beliefs affect real economic decisions? We investigate this fundamental question by comparing default rates on conventional and Islamic loans using a comprehensive monthly dataset from Pakistan that follows more than 150,000 loans over the period 2006:04 to 2008:12. We find robust...
