It is based on a new, extensive dataset not studied before. The models' hedge performance is assessed and it turns out to be unsatisfactory in a basic setting. Thus, this model setting is extended and further investigated. Moreover, an investigation of implied model parameters shows that these are not stable, especially during some periods of the considered sample. An empirical investigation is carried out to rationalize their dynamics. Finally, the basic setting is extended by introducing parameter uncertainty and empirically examined. Parameter uncertainty is then linked to the distribution of spreads of credit default swaps in a reference portfolio.Credit RiskCredit Default SwapCollateralized Debt ObligationDerivative PricingHedgingPricing and Hedging of Collateralized Debt Obligationsdissertation project
