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...

This review of the pricing of credit swaps, a form of derivative security that can be viewed as default insurance on loans or bonds, begins with a description of the credit swap contract, turns to pricing by reference to spreads over the risk-free rate of par floating-rate bonds of the same quality, and then considers model-based pricing. The role of asset swap spreads as a reference for pricin...

Credit default swaps (CDSs) are thought to ease borrowing by protecting lenders against default. This paper develops a model of the demand for CDS when borrowers choose the riskiness of investment and verification is imperfect. The model shows that CDSs may lead to risk-shifting, increasing the probability of default. Our model provides new insights on the role of CDS during the recent financia...

In this paper, we review recent advances in pricing tranches of a collateralized debt obligations and credit default swap indexes: one factor Gaussian copula model and its extensions, the structural model, and the loss process model. Then, we propose using heavy-tailed functions in future research. As background, we provide a brief explanation of collateralized debt obligations, credit default ...

In this note the pricing of options on credit default swaps using the survival-measure-pricing technique is discussed. In particular, we derive a modification of the famous Black (1976) futures pricing formula which applies to options on CDS, and show how other pricing formulae can be easily derived if the dynamics of the forward CDS rates are specified differently. The main tool in the derivat...

This paper develops a two-dimensional structural framework for valuing credit default swaps and corporate bonds in the presence of default contagion. Modelling the values of related firms as correlated geometric Brownian motions with exponential default barriers, analytical formulae are obtained for both credit default swap spreads and corporate bond yields. The credit dependence structure is i...

This paper presents a conceptual framework for valuation of single-name credit derivatives, and recuperates, in some cases generalizing, a few of known results in credit risk theory. Valuation is viewed with respect to a given state price density and relative to a general numeraire. Default probabilities and recoveries are considered as processes adapted to a subfiltration, following Jeanblanc ...

We examine the effect of introducing credit default swaps (CDSs) on firms’ investment and financing policies. Our model allows for dynamic investment and dynamic financing using equity and debt, and debt holders can trade in the CDS market. After calibrating the model, we compare an economy with a CDS market to an economy without one. The model contains both positive and negative effects of CDS...
