Long-term health insurance contracts provide policyholders with the option of lapsing coverage or switching to another tariff within the same insurance company. We empirically analyze policyholder behavior regarding contract commitment in a large dataset of German private health insurance...

<Para ID="Par1">Similarly to the notion of modeling credit risk by using forward credit default spread rates, mortality risk in life insurance contracts is nowadays often modeled by using forward mortality (spread) rates. More recently, this concept has also been discussed for more complex life insurances that...</para>

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 study a classical continuous-time consumption-investment problem of a power utility investor with deterministic labor income with the important feature that the consumption-investment process is constrained to be deterministic. This is motivated by the design of modern pension schemes of...

We derive worst-case scenarios in the case where the interest rate and the various transition intensities in a life insurance model are mutually dependent. Examples of this dependence are that surrender intensities and interest rates are high at the same time, that mortality intensities of a...
