Let I be a countable index set, and let P be a probability measure on C[0, 1]I such that the coordinate process satisfies an infinite-dimensional stochastic differential equation dX = dW+b(X,t)dt. In contrast to the finite-dimensional case, the time reversed process cannot always be described by...

The article analyzes optimal portfolio choice of utility maximizing agents in a general continuous-time financial market model under a joint budget and downside risk constraint. The risk constraint is given in terms of a class of convex risk measures. We do not impose any specific assumptions on...

Demographic projections of future mortality rates involve a high level of uncertainty and require stochastic mortality models. The current paper investigates forward mortality models driven by a (possibly infinite-dimensional) Wiener process and a compensated Poisson random measure. A major...

Erklärungsansätze für Koalitionsbildungen im Rahmen der Corporate Governance bieten die traditionellen agencytheoretischen Modelle und Quasi-Renten-Ansätze einerseits und die Organisations- und Stewardship-Theorie andererseits. Während sich die beiden erstgenannten Ansätze ausschließlich...
