We study path-dependent backward stochastic differential equations (BSDEs) with jumps. In this context path-dependence of a BSDE is the dependence of the BSDE-terminal condition and the BSDE-generator of a path of a càdlàg process. We study the path-differentiability of BSDEs of this type and...

We provide a proof for the functional Feynman-Kac Theorem for jump diffusions with path-dependent coefficients. To obtain this result we first study the existence and uniqueness of solutions to functional jump diffusions and derive a useful bound for the solution. We apply our results to the...

We investigate the problem of modeling defaults of dependent credits. In the framework of the class of structural default models we study threshold models where for each credit the underling ability-to-pay process is a transformation of a Wiener processes. We propose a model for dependent...

We investigate default probabilities and default correlations of Merton-type credit portfolio models in stress scenarios where a common risk factor is truncated. The analysis is performed in the class of elliptical distributions, a family of light-tailed to heavy-tailed distributions...

Stochastische Grundlagen für das Risikomanagement von Kreditportfolien Neuere Entwicklungen im Portfolio- und Risikomanagement sind von der Suche nach quantitativen Modellen für die Risikobeurteilung motiviert. Mertons Firmenwertmodell wird in einem Portfoliokontext dargestellt. In diesem...
