Künstliche Intelligenz (KI) und Machine Learning (ML) gelten gegenwärtig als probate Mittel, um betriebswirtschaftliche Entscheidungen durch mathematische Modelle zu optimieren. Allerdings werden die Technologien häufig in Form von "Black Box"-Ansätze mit entsprechenden Risiken realisiert....

Dieser Beitrag vergleicht die Gerechtigkeitssemantik, die auf eine lange Tradition zurückblicken kann, mit der vergleichsweise jungen Nachhaltigkeitssemantik. Basierend auf diesem Vergleich werden drei Vorzüge der Nachhaltigkeitssemantik herausgearbeitet. Sie bestehen darin, (a) eine...

Even if the correct modeling of default dependence is essential for the valuation of portfolio credit derivatives, for the pricing of synthetic CDOs a one-factor Gaussian copula model with constant and equalpairwise correlationsfor all assets in the reference portfolio has become the standard...

We investigate the robustness of existing methods to calibrate the Cheyette interest rate model to at-the-money swaption, caps and floors. Existing algorithms may fail, because they suffer from numerical instability of derivatives. Therefore, we apply derivative-free techniques and find that...

The paper presents a detailed documentation of the underlying concepts and methods of the Spatial Agent-based Competition Model (SpAbCoM). For instance, SpAbCoM is used to study firms' choices of spatial pricing policy (GRAUBNER et al., 2011a) or pricing and location under a framework of...
