This paper examines the validity of ratings assigned by rating agencies on structured products: ABS and ABS CDO. The rating agencies have been criticized for assigning AAA ratings to the structured products created from mortgages. The ratings might give a false sense of confidence to investors...

We devise simulation/regression numerical schemes for pricing the CVA on CDO tranches, where CVA stands for Credit Valuation Adjustment, or price correction accounting for the defaultability of a counterparty in an OTC derivatives transaction. This is done in the setup of a continuous-time...

The shape of the term structure of credit default swap (CDS) spreads displays large variations over time and across firms. Consistent with the predictions of structural models of credit risk, we find that the slope of CDS spread term structure increases with firm leverage and volatility, but...

This article presents a new model for valuing financial contracts subject to credit risk and collateralization. Examples include the valuation of a credit default swap (CDS) contract that is affected by the trilateral credit risk of the buyer, seller and reference entity. We show that default...

This paper analyzes the effectiveness of hedging a defaultable bond, that may not be at par, with a credit default swap (CDS) by quantifying the variance of the hedging errors and determining the optimal hedge ratio. The static hedging framework uses bond recovery and time to default, which are...

This paper presents a new statistical arbitrage test which has lower Type I error and selects arbitrage opportunities with lower downside risk than existing alternatives. The test is applied to credit derivatives markets using strategies combining Credit Default Swaps and Asset Swaps. Using four...

Developing analytic techniques for potential future exposure (PFE) of a general type transaction and applying it to credit value adjustment (CVA) and wrong way risk (WWR). The solutions provide a transparent and computationally friendly analytic formulas and good quality analytic estimates of...

This article presents a new model for valuing a credit default swap (CDS) contract that is affected by multiple credit risks of the buyer, seller and reference entity. We show that default dependency has a significant impact on asset pricing. In fact, correlated default risk is one of the most...
