Mean-variance portfolio selection for a non-life insurance company

Delong, Łukasz; Gerrard, Russell - In: Computational Statistics 66 (2007) 2, pp. 339-367

We consider a collective insurance risk model with a compound Cox claim process, in which the evolution of a claim intensity is described by a stochastic differential equation driven by a Brownian motion. The insurer operates in a financial market consisting of a risk-free asset with a constant...

Minimizing the ruin probability allowing investments in two assets: a two-dimensional problem

Azcue, Pablo; Muler, Nora - In: Computational Statistics 77 (2013) 2, pp. 177-206

We consider in this paper that the reserve of an insurance company follows the classical model, in which the aggregate claim amount follows a compound Poisson process. Our goal is to minimize the ruin probability of the company assuming that the management can invest dynamically part of the...

Dual methods for probabilistic optimization problems *

Dentcheva, Darinka; Lai, Bogumila; Ruszczyński, Andrzej - In: Computational Statistics 60 (2004) 2, pp. 331-346

We consider nonlinear stochastic optimization problems with probabilistic constraints. The concept of a p-efficient point of a probability distribution is used to derive equivalent problem formulations, and necessary and sufficient optimality conditions. We analyze the dual functional and its...

Set-valued duality theory for multiple objective linear programs and application to mathematical finance

Heyde, Frank; Löhne, Andreas; Tammer, Christiane - In: Computational Statistics 69 (2009) 1, pp. 159-179

We develop a duality theory for weakly minimal points of multiple objective linear programs which has several … are hyperplanes. As in other set-valued (but not in vector-valued) approaches, there is no duality gap in the case that … in a complete lattice. Thus the duality theory has a high degree of analogy to its classical counterpart. Another …

Multiple Fund Investment Situations and Related Games

Wintein, Stefan; Borm, Peter; Hendrickx, Ruud; Quant, … - In: Computational Statistics 63 (2006) 3, pp. 413-426

This paper deals with interactive multiple fund investment situations, in which investors can invest their capital in a number of funds. The investors, however, face some restrictions. In particular, the investment opportunities of an investor depend on the behaviour of the other investors....
