Standard factor models imply a linear relationship between expected returns on assets and their factor exposures. We provide the asymptotic properties of factor-model-based expected return estimators for individual assets and show that exploiting this linear relationship leads to precision gains...

Regulators often set value-at-risk (VaR) constraints to limit the portfolio risk of institutional investors. For some investors, notably pension funds, the VaR constraint is enforced over a horizon which is significantly shorter than the investment horizon of the investor. Our paper aims to...

Groups of agents, such as participants in a collective pension fund, can decide to undertake a joint investment and to define, ex ante, a rule for the division of proceeds. The collective investment decision and the allocation rule together form a risk sharing scheme. Such a scheme defines a...

Studies have found evidence that seemingly irrelevant details of an income component such as its label have an effect on how it is used. Using a data set with more than one million employee-month observations, we investigate the role of functional form assumptions and time aggregation in the...

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 vast literature on extrapolative stochastic mortality models mainly focuses on the extrapolation of past mortality trends and summarizes the trends by one or more latent factors. However, the interpretation of these trends is typically not very clear. On the other hand, explanation methods...
