Welfare analysis of bank capital requirements with endogenous default

We analyze the response of social welfare to a negative technology shock under different capital requirement regimes with and without default. We show that including default as an additional indicator of capital requirements is welfare improving. When […]

First, we demonstrate that formal […]
