Title: The Effects of Capital Requirements on Good and Bad Risk-Taking

Abstract: We study optimal capital requirement regulation in a dynamic quantitative model in which deposits are held by firms for precautionary reasons and facilitate their acquisition of production inputs. We identify a novel general equilibrium effect that drives a wedge between the private value of deposits (i.e., the value to a price-taking firm, measured by the deposit premium) and the social value of deposits (i.e., the value that matters for regulation). The wedge reduces the social value of deposits, and as a result, the optimal capital requirement is substantially higher than in comparable models in the literature. We find that the optimal capital requirement is 20.6%, and a regulator that ignores our novel channel would instead choose a 16% capital requirement.
