Capital regulation and tail risk

The paper studies risk mitigation associated with capital regulation, in a context when banks may choose tail risk assets. We show that this undermines the traditional result that higher capital reduces excess risk-taking driven by limited liability. When capital raising is costly, poorly capitalized banks may limit risk to avoid breaching the minimal capital ratio. A bank with higher capital has less chance of breaching the ratio, so may actually take more risk. As a result, banks which have access to tail risk projects may take greater risk when highly capitalized. The results are consistent with stylized facts about pre-crisis bank behavior, and suggest implications for the optimal design of capital regulation

Foreign ownership, bank information environments, and the international mobility of corporate governance

This paper investigates how foreign ownership shapes bank information environments. Using a sample of listed banks from 60 countries over 1997–2012, we show that foreign ownership is significantly associated with greater (lower) informativeness (synchronicity) in bank stock prices. We also find that stock returns of foreign-owned banks reflect more information about future earnings. In addition, the positive association between price informativeness and foreign ownership is stronger for foreign-owned banks in countries with stronger governance, stronger banking supervision, and lower monitoring costs. Overall, our evidence suggests that foreign ownership reduces bank opacity by exporting governance, yielding important implications for regulators and governments
