The credit valuation adjustment (CVA) of OTC derivatives is an important part of the Basel III credit risk capital requirements and current accounting rules. Its calculation is not an easy task - not only it is necessary to model the future value of the derivative, but also the probability of...

In this paper we present a tree model for defaultable bond prices which can be used for the pricing of credit derivatives. The model is based upon the two-factor Hull-White (1994) model for default-free interest rates, where one of the factors is taken to be the credit spread of the defaultable...

In this paper a new credit risk model for credit derivatives is presented. The model is based upon the Libor market modelling framework for default-free interest rates. We model effective default-free forward rates and effective forward credit spreads as lognormal diffusion processes, and...

Spreads of agency mortgage-backed securities (MBS) vary significantly in the cross section and over time, but the sources of this variation are not well understood. We document that, in the cross section, MBS spreads adjusted for the prepayment option show a pronounced smile with respect to the...

We propose a simple computational method for constructing an arbitrage-free CDO pricing model which matches a pre-specified set of CDO tranche spreads. The key ingredient of the method is a formula for computing the local default intensity function of a portfolio from its expected tranche...

I propose a new procedure for extracting probabilities of default from structural credit risk models based on model implied credit spreads (MICS) and implement this approach assuming a barrier option framework nesting the Merton (1974) model of capital structure. MICS are the increase in the...

We present an integrated framework incorporating both exogenous liquidity risk in the secondary corporate bond market and volatility risk in the dynamics of asset value in debt rollover models. Using an innovative theoretical approach we derive general expressions for the debt and equity values...

Based on the works of Brockman and Turtle (2003) and Giesecke (2004), we propose in this study a hybrid barrier option model to explain observed credit spreads. It is free of problems with the structural model which underprescribed credit spreads for investment grade corporate bonds and...

This paper presents a joint analysis of the term structure of credit default swap (CDS) spreads and the implied volatility surface. The rapid development of the CDS market has provided convenient products to extract credit risk, and its interaction with equity volatility has been analyzed in...

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...
