In competitive capital markets, risky debt claims that offer high yields in good times have high systematic risk exposure in bad times. We apply this idea to bank risk measurement. We find that banks with high accounting return on equity (ROE) prior to a crisis have higher systematic tail risk...

Despite plenty of anecdotal evidence of hidden losses in banks, there is no systematic study analyzing the economic drivers of this behavior: we simply do not get to observe what banks are hiding unless they are caught. Using a regulatory change in India that forced all commercial banks to...

We adapt structural models of default risk to take into account the special nature of bank assets. The usual assumption of log-normally distributed asset values is not appropriate for banks. Typical bank assets are risky debt claims, which implies that they embed a short put option on the...

In competitive capital markets, portfolios of risky debt claims have high systematic risk exposure in bad times if they offer a high "yield" in good times. We apply this idea to measurement of bank risk. Rather than trying to directly measure asset risks on the balance sheet — the typical...

We study the key drivers of security design in the residential mortgage-backed security (RMBS) market during the run-up to the subprime mortgage crisis. We show that deals with a higher level of equity tranche have a significantly lower delinquency rate conditional on observable loan...
