Zusammenfassung:This paper (i) reviews the different channels of transmission of prudential policy highlighted in the literature and (ii) provides a quantitative assessment of the impact of Basel III reforms using several policy-oriented DSGE models. It shows that the long-term effects on GDP of higher capital requirements are positive when the associated benefits are accounted for in addition to their costs. However, the results crucially depend on assumptions about crisis probability and severity. For liquidity regulations, only models capturing benefits of increased liquidity (e.g., preventing bank runs) show a net benefit.
