We study optimal capital requirement regulation in a dynamic quantitative model in which nonfinancial firms, as well as households, hold deposits. Firms hold deposits for precautionary reasons and to facilitate the acquisition of production inputs. Our theoretical analysis identifies a novel...

This study develops a multi-period structural model to value bank subordinated debt (subdebt) under different regulatory policies. The model provides a complete framework for analyzing how various factors, such as credit and interest rate risks, bank characteristics and regulatory policies...

Advocates for internal model-based capital regulation argue that this approach will reduce costs and remove distortions that are created by rules-based capital regulations.

This paper analyzes the new Basel Accord abilities to reduce the externalities that result from the underpriced deposit insurance. A moral hazard framework is adopted to describe the optimal behavior of banks that endogenously select the characteristics of their credit portfolio in order to...
