The problem of valuation of life insurance payments with policyholder behaviour is studied. First a simple survival model is considered, and it is shown how cash flows without policyholder behaviour can be modified to include surrender and free policy behaviour by calculation of simple integrals. In the second part, a more general disability model with recovery is studied. Here, cash flows are ...

For solvency purposes insurance companies need to calculate so-called best-estimate reserves for outstanding loss liability cash flows and a corresponding risk margin for nonhedgeable insurance-technical risks in these cash flows. In actuarial practice, the calculation of the risk margin is often not based on a sound model but various simplified methods are used. In the present paper we properl...

We study the unconstrained project scheduling problem with discounted cash flows where the net cash flows are assumed to be linear dependent on the completion times of the corresponding activities. The objective is to schedule the activities in order to maximize the net present value (npv) subject to the precedence constraints and a fixed deadline. We present an efficient enumeration algorithm ...

This paper estimates the foreign exchange rate exposure of 6,917 U.S. nonfinancial firms on the basis of stock prices and corporate cash flows. The results show that several firms are significantly exposed to at least one of the foreign exchange rates Canadian Dollar, Japanese Yen and Euro, and significant exposures are more frequent at longer horizons. The percentage of firms for which stock p...
