In this article we review the state of play in the use of stochastic models for the measurement and management of longevity risk. A focus of the discussion concerns how robust these models are relative to a variety of inputs: something that is particularly important in formulating a risk...

We derive risk-neutral option price formulas for plain-vanilla temperature futures derivatives on the basis of several multi-factor Ornstein-Uhlenbeck temperature models which allow for seasonality in the mean level and volatility. Our main innovation consists in an incorporation of omnipresent...

In this paper, we investigate the dynamics of age-cohort survival curves under the assumption that the instantaneous mortality intensity is driven by an affine jump-diffusion (AJD) process. Advantages of an AJD specification of mortality dynamics include the availability of closed-form...

One of the main tasks in non-life insurance is the prediction of outstanding loss liabilities for run-off portfolios. Additionally, the quantification of the prediction uncertainty is also of great interest. In this paper we look at this actuarial problem in a bivariate framework, i.e. we assume...

This paper uses a modification of the Random Forest classification algorithm to predict insolvency of insurers. RF orders companies according to their propensity to default. We show that RF methodology delivers higher quality of prediction compared to other existing methods. In addition, RF...

The Lee-Carter model is a basic approach to forecasting mortality rates of a single population. Although extensions of the Lee-Carter model to forecasting rates for multiple populations have recently been proposed, the structure of these extended models is hard to justify and the models are...
