In the last decade, portfolio credit risk measurement has improved significantly. The current state-of-the-art models analyze the value of the portfolio at a certain risk horizon, e.g. one year. Most popular has become the Merton-type one-factor model of Vasicek, that builds the fundament of the...

According to the new capital adequacy framework (Basel II) finally adopted by the Basel Committee in June 2004 the eligibility of collaterals, especially financial collaterals, is extended in comparison to the existing rules. However, financial assets are valued conservatively in the credit...

Gemäß den im Juni 2004 durch den Baseler Ausschuss endgültig verabschiedeten Kapitalstandards (Basel II) sind Kredite in Höhe des so genannten unerwarteten Verlusts mit Eigenkapital zu unterlegen. Für erwartete Verluste hat das jeweilige Kreditinstitut Rückstellungen zu bilden, wobei hier...

The objective of this research is to develop a structural form probability of default model for small and medium-sized enterprises, dealing with the methodological issues which arise in the modelling of small commercial loan portfolios, and to test the applicability of the model in practice....

A model is presented of bank behaviour which identifies the factors determining a bank's optimal capital/asset ratio, its optimal liquidity ratio, the expected value of non-performing loans and the probability of bank failure. We propose that this last variable can act as an index of bank...

We analyse a model in which bank deposits are insured and there is an exogenous cost of bank capital. The former effect results in bank over-investment and the latter in under-investment. Regulatory capital requirements introduce investment distortions, which are a constrained optimal response...
