Dirac Processes and Default Risk

Default Priors for Gaussian Processes

Motivated by the statistical evaluation of complex computer models, we deal with the issue of objective prior specification for the parameters of Gaussian processes. In particular, we derive the Jeffreys-rule, independence Jeffreys and reference priors for this situation, and prove that the resulting posterior distributions are proper under a quite general set of conditions. A proper flat prior...

Measuring Default Risk Premia from Default Swap Rates and EDFs

This paper estimates the degree of variation over time in the price for bearing exposure to U.S. corporate default risk during 2000-2004, based on the relationship between default probabilities, as estimated by Moody’s KMV EDFs, and default swap (CDS) market rates. The default-swap data, obtained through CIBC from 39 banks and specialty dealers, allow us to establish a strong link between actua...

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...
