Several models of how to price synthetic CDOs are presented. The study focuses on comparison of classical Gaussian copula with NIG copula, double t-copula and gaussian stochastic correlation model. Because the the t-copula is technically the most demanding of the presented approaches and usually...

Modeling the portfolio credit risk is one of the crucial issues of the last years in the financial problems. We propose the valuation model of Collateralized Debt Obligations based on a one- and two-parameter copula and default intensities estimated from market data. The presented method is used...

Banks increasingly recognize the need to measure and manage the credit risk of their loans on a portfolio basis. We address the subportfolio "middle market". Due to their specific lending policy for this market segment it is an important task for banks to systematically identify regional and...
