This paper develops a model of banking to study the risk-taking consequences of contingent capital (CC). It begins with the observation that partial conversion of CC provides its owners with a portfolio of equity and debt. Since the former (latter) asset typically induces a preference for risk...

We assess the impact of leverage ratio (LR) requirements on risk-taking behaviour of banks theoretically, using a simple model, and empirically, using a difference-in-differences analysis that compares behaviour of banks subject to UK LR requirements (LR-banks) to otherwise similar banks...

As a result of the Enron scandal, new regulations were enacted that increased the capital charge for holding assets in off-balance sheet vehicles. I utilize a triple difference specification to identify the effect of this exogenous regulatory shock on bank systematic risk exposure. I find that...

History shows that prohibition diminishes the supply of capital and raises its returns. However, for value-added investors such as private equity investments, regulation potentially reduces capital quality. The regulatory measures introduced in Basel II Capital Framework and in the EU Capital...

The article deals with the liquidity risk in the banks in the context of the financial crisis. At first, the balance sheet and market liquidity are defined and the main principles of the methods for measuring liquidity risk, which banks use, are identified. Then follow review of main challenges...

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...

Since the global financial crisis and the related restructuring of banking systems, bank concentration is on the rise in many countries. Consequently, bank size and its role for macroeconomic volatility (or: stability) is the subject of intense debate. This paper analyzes the effects of...

The internal ratings-based (IRB) approach maps banks’ risk profiles more adequately than the standardized approach. After switching to IRB, banks’ risk-weighted asset (RWA) densities are thus expected to diverge, especially across countries with different supervisory strictness and risk...

The internal ratings-based (IRB) approach maps bank risk profiles more adequately than the standardized approach. After switching to IRB, banks' risk-weighted asset (RWA) densities are thus expected to diverge, especially across countries with different supervisory strictness and risk levels....

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...
