The aim of this paper is to extend the results of Jarrow, Yu (2001) onthe spread term structures of corporate bonds. We first consider differentcharacterisations of these term structures, when the available informationcorresponds to the default histories of the firms. The approach is then...

Credit limit management is of paramount importance for successful short-term credit-risk management, even more so when the situation in credit and financial markets is tense. We consider a continuous-time model where the credit provider and the credit taker interact within a game-theoretic...

We introduce an adaptive importance sampling method for the loss distribution of credit portfolios based on the Robbins-Monro stochastic approximation procedure. After presenting the subtle construction of the algorithm, we apply our adaptive scheme for calculating the risk figures of a typical...

We analyze the connections between the credit spreads that the same credit risk commands in different currencies. We show that the empirically observed differences in these credit spreads are mostly driven by the dependency between the default risk of the obligor and the exchange rate. In our...

We propose a new nonlinear classification method based on a Bayesian "sum-of-trees" model, the Bayesian Additive Classification Tree (BACT), whichextends the Bayesian Additive Regression Tree (BART) method into the classification context. Like BART, the BACT is a Bayesian nonparametric...

In 2004 the Basel Committee published an extensive revision of the capital charges whichcreates more risk sensitive capital requirements for banks. The New Accord called “InternationalConvergence of Capital Measurement and Capital Standard” provides in its first pillarfor a finer measurement...

This paper tracks a structured financial innovation, the commercial mortgage-backed securitywhich is not as novel as current discussion around the sub-prime crisis let assume. However,CMBS as credit-derivatives feature various factors that influence the risks arising from acommercial-mortgage...

Loss Given Default (LGD) is a major element for pricing credits and bonds. As there has beena substantial amount of research during the last years, this paper aims to give an overview.Initially, defaults and recovery definitions for credits and the differences to bonds are discussed.A survey of...
