In [10] we presented a reduced form of risky bond pricing. At the default date a bond seller fail to continue fulfill his obligation and the price of the bond sharply drops down. If the face value of the defaulted bond for no-default scenarios is $1 then the bond price just after default is...

We introduce a novel class of credit risk models in which the drift of the survival process of a firm is a linear function of the factors. The prices of defaultable bonds and credit default swaps (CDS) are linear-rational in the factors. The price of a CDS option can be uniformly approximated by...

The ground-breaking Black-Scholes-Merton model has brought about a generation of derivative pricing models that have been successfully applied in the financial industry. It has been a long standing puzzle that the structural models of credit risk, as an application of the same modeling paradigm,...

By reinterpreting the calibration of structural models, a reassessment of the importance of the input variables is undertaken. The analysis shows that volatility is the key parameter to any calibration exercise, by several orders of magnitude. To maximize the sensitivity to volatility, a simple...

The theory of pricing to acceptability developed for incomplete markets by Cherny and Madan (2009b) is applied to marking ones own default risk. It is observed in agreement with Heckman (2004), that assets and liabilities are not to be priced under fair value accounting principles at the same...

We study the valuation of contingent credit default swaps (C-CDS) where the underlying is an interest rate swap and swap rate follows a diffusion process with a one-time jump at default. Our method extends the standard Black (1976) model for interest rate swaption to (1) swaption expires at a...

In the first part we consider a dynamical model for the number of defaults of a pool of names. The model is based on the notion of generalized Poisson process, allowing for more than one default in small time intervals, contrary to many alternative approaches to loss modeling. We illustrate how...

We exploit emerging market sovereign CDS spreads to examine the reaction of sovereign credit risk to changes in country-specific and global financial factors. Utilizing a VAR model fitted with DCC GARCH, we find that comovements of spreads generally exhibit significant time-varying correlations,...
