Microprudential Regulation in a Dynamic Model of Banking

Deskripsi

This paper studies the quantitative impact of microprudential bank regulations on bank lending and value metrics of efficiency and welfare in a dynamic model of banks that are financed by debt and equity, undertake maturity transformation, are exposed to credit and liquidity risks, and face financing frictions. We show that: (a) there exists an inverted U?shaped relationship between bank lending, welfare, and capital requirements; (b) liquidity requirements unambiguously reduce lending, efficiency and welfare; and (c) resolution policies contingent on observed capital, such as prompt corrective action, dominate in efficiency and welfare terms (non?contingent) capital and liquidity requirements.
