In spite of mounting losses banks continued to pay dividends during the crisis. We present a model that addresses this behavior. By paying out dividends, a bank transfers value to its shareholders away from creditors, among whom are other banks. This way, one bank's dividend payout policy...

While losses were accumulating during the 2007-09 financial crisis, many banks continued to maintain a relatively smooth dividend policy. We present a model that explains this behavior in a setting where there are financial externalities across banks. In particular, by paying out dividends, a...

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...

Since the 2008 global financial crisis, and after decades of relative neglect, the importance of the financial system and its episodic crises as drivers of macroeconomic outcomes has attracted fresh scrutiny from academics, policy makers, and practitioners. Theoretical advances are following a...

Can banks maintain their advantage as liquidity providers when they are heavily exposed to a financial crisis? The standard argument - that banks can - hinges on deposit inflows that are seeking a safe haven and provide banks with a natural hedge to fund drawn credit lines and other commitments....

Bailing out banks requires overcoming debt overhang as well as dealing with adverse selection with respect to the quality of banks' balance sheets, in terms of heterogeneity in both the likelihood and extent of their potential shortfalls, of future asset values vis-à-vis contractual debt...

We analyze government interventions to alleviate debt overhang among banks. Interventions generate two types of rents. Informational rents arise from opportunistic participation based on private information while macroeconomic rents arise from free riding. Minimizing informational rents is a...

This paper explores financial stability policies for the shadow banking system. I tie policy options to economic mechanisms for shadow banking that have been documented in the literature. I then illustrate the role of shadow bank policies using three examples: agency mortgage real estate...

I propose a simple theory of intertwined business and financial cycles, where financial regulation both optimally responds to and influences the cycles. In this model, banks do not internalize the effect of their credit expansion on other banks’ expected bankruptcy costs, which leads to...

We analyze securities trading by banks and the associated spillovers to the supply of credit. Empirical analysis has been elusive due to the lack of securities register for banks. We use a unique, proprietary dataset that has the investments of banks at the security level for 2005-2012 in...
