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...

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...
