We propose a theory of bank behaviour under capital requirements that accounts for both risk-shifting incentives and debt overhang considerations. A key result is that the bank's lending response to an increase in the requirement need not be negative. The sign and the magnitude of the response...

I study economies where banks do not fully internalize the social costs of default, which distorts their lending decisions. In all these economies, a common general equilibrium effect leads to aggregate over-investment. As a result, under laissez-faire, crises are too frequent and too costly...

We estimate the effect of changes in microprudential regulatory capital requirements on bank capital ratios and bank lending. We do so by running panel regressions using a rich new data set, exploiting variation in individual bank capital requirements in the United Kingdom from 1990-2011. There...
