Many regulations that affect firms and banks in the economy are based on size thresholds. We develop a model that shows that such regulations distort risk-taking incentives, providing above-threshold firms with greater incentives to take risk and below-threshold firms the opposite. Risk...

We empirically investigated the impact of regulatory risk retention methods on credit ratings and pricing at issuance using a sample of European securitization tranches issued in the period 2011-2021. European regulation is based on the assumption that all risk retention methods homogenously...

This paper proposes Spillover Persistence as a measure for financial fragility. The volatility paradox predicts that fragility builds up when volatility is low, which challenges existing measures. Spillover Persistence tackles this challenge by exploring a novel dimension of systemic risk: loss...

We examine how regulatory uncertainty impacts the credit spreads of covered bonds issued by U.S. domiciled banks. Using data on covered bonds issued by Washington Mutual and Bank of America, for the September 2006 to December 2016 period, we find that investors require an incremental spread that...

The lack of portfolio granularity in terms of exposure has been shown to have important implications for the amount of a financial institution's economic capital. Based on a numerical simulation model, we provide concrete examples of how granularity affects capital levels. We achieve this by...

We show that banks' risk exposure in one asset category affects how they report regulatory risk weights for another asset category. Specifically, banks report lower credit risk weights for their loan portfolio when they face higher risk exposure in their trading book. This relationship is...

The paper analyzes a very stylized model of crises and demonstrates how the degree of strategic complementarity in the actions of investors is a critical determinant of fragility. It is shown how the balance sheet composition of a financial intermediary, parameters of the information structure...

This paper adopts a dynamic contracting framework to study the design of prudential regulation of a bank engaging in excessive risk-taking. The bank's manager can enhance short term profits by either exerting effort or taking on excessive risk, which increases the bank's exposure to tail risk....

The U.S. financial system faces a major, growing, and much under-appreciated threat from the Federal Reserve's risk modeling agenda — the “Fed stress tests.” These were intended to make the financial system safe but instead create the potential for a new systemic financial crisis.The...
