Credit Derivatives in an Affine Framework

Abstract

We develop a general and efficient method for valuating credit derivatives based on multiple entities in an affine framework. This includes interdependence of market and credit risk, joint credit migration and counterparty default risk of multiple firms. As an application we provide closed form expressions for the joint distribution of default times, default correlations, and credit default spreads in the presence of counterparty default risk.credit derivatives, joint default correlation, affine models
