The subject of the present paper is a simplified model for a symmetric bistable system with memory or delay, the reference model, which in the presence of noise exhibits a phenomenon similar to what is known as stochastic resonance. The reference model is given by a one dimensional parametrized...

Up until the appearance of early insurance, fi nancial relief for victims of natural hazards was characterised by two facts: First, private support to victims was provided on a purely voluntary basis. Second, help was only given after an extreme event had happened. "Charity" of this sort was...

As a main step in the numerical solution of control problems in continuous time, the controlled process is approximated by sequences of controlled Markov chains, thus discretizing time and space. A new feature in this context is to allow for delay in the dynamics. The existence of an optimal...

This paper analyzes the effect of the removal of government guarantees on bank risk taking. We exploit the removal of guarantees for German Landesbanken which results in lower credit ratings, higher funding costs, and a loss in franchise value. This removal was announced in 2001, but...

Staaten gewähren Banken oft Garantien, um den Zusammenbruch des Finanzsystems zu verhindern. Diese Garantien müssen aber sobald wie möglich wieder zurückgenommen werden. Zuvor sollten jedoch die möglichen Auswirkungen der Abschaffung einer Garantie untersucht werden. Die so gewonnenen...

In this paper we consider an insider with privileged information that is affected by an independent noise vanishing as the revelation time approaches. At this time, information is available to every trader. Our financial markets are based on Wiener space. In probabilistic terms we obtain an...

We consider the problem of numerical approximation for forward-backward stochastic differential equations with drivers of quadratic growth (qgFBSDE). To illustrate the significance of qgFBSDE, we discuss a problem of cross hedging of an insurance related financial derivative using correlated...
