Using banks' internal models for regulatory purposes, while aimed at making capital requirements more accurate, invites regulatory arbitrage. I show how the strategic use of risk models can be avoided by penalizing banks with low risk-weights when they suffer abnormal losses. As defaulting banks...

The regulatory use of banks' internal models makes capital requirements more risk-sensitive but invites regulatory arbitrage. I develop a framework to study bank regulation with strategic selection of risk models. A bank supervisor can discourage arbitrage by auditing risk models, and implements...

This paper proposes a quantitative multi-sector DSGE model with bank failure and firm default to study the interactions between bank regulation and climate policy. Households value the liquidity of deposits, which are protected by deposit insurance. Banks collect deposits and issue equity to...

In the presence of macroeconomic shocks severe enough to threaten the liquidity or solvency of the banking system, the regulator can rely on the funds concentration effect to save long-term investment projects. Some banks are forced into bankruptcy with the result that other banks obtain more...

This paper offers a framework for regulating internalities. Using a simple economic model, we provide four principles for designing and evaluating behaviorally-motivated policy. We then outline rules for determining which contexts reliably reflect true preferences and discuss empirical...

While there is a growing debate among researchers and practitioners on the possible role of central banks and financial regulators in supporting a smooth transition to a low-carbon economy, the information on which macroprudential instruments could be used for reaching the "green structural...

The German Commercial Code (HGB) allows banks to build visible reserves for general banking risks according to section 340g HGB. These GBR reserves may, in addition to their risk provisioning function, be used to enhance capital endowment, for internal financing, signaling or earnings management...

The General Agreement on Trade in Services (known as the GATS) is an important new element in the international framework that affects the regulation of every WTO Member's financial sector. However, except for a limited number of country-specific case studies, no attempt has been made to compare...

We measure the impact of bank capital requirements on corporate borrowing and investment using loanE level data. The Basel II regulatory framework makes capital requirements vary across both banks and across firms, which allows us to control for firmE level credit demand shocks and bankE level...

Euro area governments have committed to break the doom loop between bank risk and sovereign risk. But policymakers have not reached consensus on whether and how to reform the regulatory treatment of banks' sovereign exposures. To inform policy discussions, this paper simulates portfolio...
