We consider longevity risk hedging problems, where survivor swaps are available as hedging instruments. As objective functions we consider the mean-variance and the mean-conditional-value-at-risk of the hedged liabilities, evaluated using an estimated probability law governing the mortality...

Forecasted mortality rates using mortality models proposed in the recent literature are sensitive to the sample size. In this paper we propose a method based on Bayesian learning to determine model-specific posterior distributions of the sample sizes. In particular, the sample size is included...

The fact that incumbent firms can immediately deduct research and development (R&D) investments from taxable income is generally believed to give them a strategic advantage over new firms that cannot deduct the investment cost, but instead generate a net operating tax loss carryover. Using an...

Changing management accounting systems requires more than appropriate implementation. It is argued that structural characteristics of an organization, centralization in particular, should also be taken into account when deciding on a change. Centralization implies higher costs of communication...

We analyze the importance of longevity risk for the solvency of portfolios of pension annuities. We distinguish two types of mortality risk. Micro-longevity risk quantifies the risk related to uncertainty in the time of death if survival probabilities are known with certainty, while...

In modeling and forecasting mortality the Lee-Carter approach is the benchmark methodology. In many empirical applications the Lee-Carter approach results in a model that describes the log central death rates by means of linear trends. However, due to the volatility in (past) mortality data, the...
