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...

Die Bankenneuregulierung der Europäische Kommission sieht eine Beschränkung der Kreditvergabe im Interbankenmarkt auf 25 % des Eigenkapitals sowie einen Selbsteinbehalt des Originators in Höhe von 5 % am gesamten zu verbriefenden Forderungsportfolio vor. Eine starre Regulierung führt aber...

Banking regulators often practice forbearance and ambiguity in insolvency resolutions. The paper examines the effects of regulatory forbearance and ambiguity in a context of allocational efficiency. Bailouts, liquidations and their stochastic policy mix lead to suboptimal allocations if banks do...

This paper examines procyclicality of the financial system. The introduction describes the natural and regulatory sources of procyclicality, focusing on the potential procyclical effect of the current Basel II regulatory framework for banks. It also mentions the regulatory tools for mitigating...

Following the Hotelling model of spatial competition used by Massoud and Bernhardt (2002) to analyze competition in ATM fees, in this paper we analyze the effects of banning fees on the usage of ATMs by account holders. We find that the prohibition also reduces the fees charged to non-account...
