Group Self-annuitisation Schemes (GSAs), or Pooled Annuity Schemes, are designed to share uncertain future mortality experience including systematic improvements. They have been proposed because of the significant uncertainty of future mortality improvement on pension and annuity costs. The...

In this paper we investigate the potential of Lévy copulas as a tool for modelling dependence between compound Poisson processes and their applications in insurance. We analyse characteristics regarding the dependence in frequency and dependence in severity allowed by various Lévy copula...

Demographic change is happening in developed countries with an ageing of the population. Individuals are financing retirement increasingly from superannuation savings and less from government pension support. A major asset that individuals have to fund their retirement is the residential home....

This paper provides a detailed quantitative assessment of the impact of solvency capital requirements on product pricing and shareholder value for a life insurer. A multi-period firm value maximization model for a life annuity provider, allowing for stochastic mortality and asset returns,...

This paper considers optimal reinsurance based on an assessment of the reinsurance arrangements for a large life insurer. The objective is to determine the reinsurance structure, based on actual insurer data, using a modified mean-variance criteria that maximises the retained premiums and...

Mortality models used to assess longevity risk and retirement funding have been extended to stochastic models with trends and systematic risk. Systematic risk cannot be readily diversified in an insurance pool or pension fund. It is an important factor in assessing solvency and highlighting the...

Systematic improvements in mortality increases dependence in the survival distributions of insured lives. This is not accounted for in standard life tables and actuarial models used for annuity pricing and reserving. Furthermore, systematic longevity risk undermines the law of large numbers; a...

It is widely accepted that mortality risk varies across individuals within age-sex bands of a population. This heterogeneity exposes insurers to adverse selection if only the healthiest lives purchase annuities, so standard annuities are priced with a mortality table that assumes above-average...

Changing demographics creates the potential for the expansion of existing and new products to manage longevity risk. Life annuities address this risk, yet these annuity product markets are thin. Insurers are concerned about the long term risks associated with these longevity products and capital...

Longevity risk is amongst the most important factors to consider for pricing and risk management of longevity products. Past improvements in mortality over many years, and the uncertainty of these improvements, have attracted the attention of experts, both practitioners and academics. Since...
