Pricing Credit Default Swaps Under Default Correlations and Counterparty Risk

In this paper, we develop a generalized affine model to characterize correlated credit risk of multi-firms. When valuing credit derivatives, this new approach allows to incorporate correlative market and credit risk, interdependent default risk structure and counterparty risk into consideration. We have demonstrated our affine model not only combines the existing structural models and intensity based models, but also produces explicit formulas for the prices of credit default swaps and other credit derivatives.
