Let's jump together: pricing credit derivatives
Joao Garcia, Serge Goossens and Wim Schoutens introduce a dynamic multivariate jump-driven model for credit spreads. The model parameters come from a calibration on swaptions and a correlation-matching procedure. The authors apply the model to credit…
Explaining the Levy base correlation smile
Joao Garcia and Serge Goossens look at base expected loss at maturity both in the Gaussian copula and Levy-based models, and link it to base correlation in these frameworks. They report on the existence of smile in both base correlation curves and…
