Description: This presentation compares continuous-time multi-factor affine cohort mortality models and presents estimation results for an affine multi-factor, multi-cohort mortality model.

Description: Pension funds are usually either defined benefit or defined contribution funds. In Australia in recent years, for a number of reasons, some pension funds have offered the 'greater of,' these two benefits. Such a benefit design can be valued using contingent claims valuation techniques since it is equivalent to an option on the maximum of two random benefit amounts - one equal to a multiple of salary and the other the accumulation of a percentage of salary at an earnings rate. This paper overviews some of the issues in applying contingent claims valuation techniques to the valuation of this style of benefit. From Actuarial Research Clearing House 1993, Vol. 1.

Description: The main aim of this paper is to apply some of the techniques of modern time series and econometric analysis to analyse investment data in order to better understand the nature of long run relationships in investment series typically used in stochastic investment models. The paper attempts to identify and address fundamental issues that need to be considered before developing a particular stochastic investment model.
