In a traditional Black-Scholes market we develop a verification theorem for a generalclass of investment and consumption problems where the standard dynamic programmingprinciple does not hold. The theorem is an extension of the standard Hamilton-Jacobi-Bellman equation in the form of a system of...

We combine a dynamic programming approach (stochastic optimal control) with a multi-stage stochastic programming approach (MSP) in order to solve various problems in personal finance and pensions. Stochastic optimal control produces an optimal policy that is easy to understand and implement....

Premium settlement and calculation of reserves and capital requirements are typically based on worst or just bad case assumptions on interest rates, mortality rates, and other transition rates. If interest and transition rates are chosen independently from each other, the worst, i.e. the reserve...

We solve the problem of an investor who maximizes utility but is uncertain about preferences. We propose a problem formulation based on expected certainty equivalents. We tackle the time-consistency issues arising from that formulation by applying the equilibrium theory approach. To this end, we...

We establish a connection between continuous-time recursive utility and the notion of consistency studied, in particular, in connection with the non-linear objective mean-variance. We propose a time-global optimization problem and show that the optimal time-consistent solution to this...

We present a verification result for a general class of portfolio problems, where the standard dynamic programming principle does not hold. Explicit solutions to a series of cases are provided. They include dynamic mean-standard deviation, endogenous habit formation for quadratic utility, and...

We control the surplus process of a non-life insurance company by dynamic proportional reinsurance. The objective is to maximize expected (utility of the) surplus under the worst-case claim development. In the large claim case with a worst-case upper limit on claim numbers and claim sizes, we...
