This paper suggests a model based on Poisson processes to estimate joint credit losses without the limitations of normality assumptions and non-negative correlation. Idiosyncratic and systematic risks are seen as “shocks” and defaults are driven by a latent variable (loans' lifetimes). The...

We integrate Basel II (and III) regulations into the industrial organization approach to banking and analyze lending behavior and risk sensitivity of a risk-neutral bank. The bank is exposed to credit risk and may use credit default swaps (CDS) for hedging purposes. Regulation is found to induce...

This paper extends the literature on bank capital structure by modeling capital structure as a function of important public policy and bank regulatory characteristics of the home country, as well as of bank-specific variables, country-level macroeconomic conditions, and country-level financial...

This paper discusses the institutional changes needed in Europe if prompt corrective action (PCA) is to be effective in supervising and resolving cross-border banking groups. The paper identifies these changes starting with enhancements in the availability of information on banking groups’...

The great financial turmoil that started 2007 has brought bank regulation back into the political debate. There is talk about imposing new regulations on banks and other financial intermediaries. Yet, we are not convinced that it is completely understood how the existing regulation affects...

So far the discussion in Switzerland about the social costs and benefits of higher capital requirements resulting from the new Basel III Accord and the Swiss Too Big To Fail legislation has been heavily qualitative. This paper provides a quantitative view and estimates the long-run costs and...

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...

In this paper we review the actual operational data of an anonymous Central European Bank, using two approaches described in the literature: the loss distribution approach and the extreme value theory (EVT). Within the EVT analysis, two estimation methods were applied; the standard maximum...

This paper focuses on how to calibrate models used to stress test the most important risks in the banking system. Based on the results of a verification of the Czech National Bank's stress testing methodology, the paper argues that stress tests should be calibrated conservatively and slightly...

One of the biggest risks arising from financial operations is the risk of counterparty default, commonly known as a credit risk. Leaving unmanaged, the credit risk would, with a high probability, result in a crash of a bank. In our paper, we will focus on the credit risk quantification...
