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...

We derive a continuous time approximation of the evolutionary market selection model of Blume and Easley (1992). Conditions on the payoff structure of the assets are identified that guarantee convergence. We show that the continuous time approximation equals the solution of an integral equation...
