We empirically assess the effect of reserve accumulation as a result of quantitative easing (QE) on bank-level lending and risk taking activity. To overcome the endogeneity of bank-level reserve holdings to banks' other portfolio decisions, we employ instruments made available by a regulatory...

We modify the Diamond and Dybvig (1983) model of banking to jointly study various regulations in the presence of credit and run risk. Banks choose between liquid and illiquid assets on the asset side, and between deposits and equity on the liability side. The endogenously determined asset...

We construct a novel U.S. data set that matches bank holding company credit default swap (CDS) positions to detailed U.S. credit registry data containing both loan and corporate bond holdings to study the effects of banks' CDS use on corporate credit quality. Banks may use CDS to mitigate agency...

We provide new evidence that credit supply shifts contributed to the U.S. subprime mortgage boom and bust. We collect original data on both government and private mortgage insurance premiums from 1999-2016, and document that prior to 2008, premiums did not vary across loans with widely different...

We find that that the Current Expected Credit Loss (CECL) standard would slightly dampen fluctuations in bank lending over the economic cycle. In particular, if the CECL standard had always been in place, we estimate that lending would have grown more slowly leading up to the financial crisis...

In this paper, we exploit a natural experiment in which thrifts in several states witnessed an exogenous reduction in supervisory attention to assess the effect of supervision on financial institutions' willingness to take risk. We show that the affected institutions took on much more risk than...

I develop a model where the sovereign debt capacity depends on the capitalization of domestic banks. Low-capital banks optimally tilt their government bond portfolio toward domestic securities, linking their destiny to that of the sovereign. If the sovereign risk is sufficiently high,...

We investigate how liquidity regulations affect banks by examining a dormant monetary policy tool that functions as a liquidity regulation. Our identification strategy uses a regression kink design that relies on the variation in a marginal high-quality liquid asset (HQLA) requirement around an...
