Asset liability matching remains an important topic in life insurance research. The objective of this paper is to find an optimal asset allocation for a general portfolio of life insurance policies. Using a multi-asset model to investigate the optimal asset allocation of life insurance reserves,...

For the valuation of reverse mortgages with tenure payments, this article proposes a specific analytic valuation framework with mortality risk, interest rate risk, and housing price risk that helps determine fair premiums when the present value of premiums equals the present value of contingent...

There has been a significant increase in the life expectancies of the Taiwanese population after the end of Second World War. Like in many developed countries, due to the prolonging life expectancy and lower fertility rates, the aging population has now become a major policy concern in Taiwan....

This research proposes a mortality model with an age shift to project future mortality using principal component analysis (PCA). Comparisons of the proposed PCA model with the well-known models--the Lee-Carter model, the age-period-cohort model (Renshaw and Haberman, 2006), and the Cairns,...

This research studies the interaction between longevity risk and asset allocation for a defined contribution pension plan. We investigate the investment strategy during the accumulation phase to deal with longevity risk during the decumulation phase. The longevity risk is demonstrated using the...

In the classical Lee-Carter model, the mortality indices that are assumed to be a random walk model with drift are normally distributed. However, for the long-term mortality data, the error terms of the Lee-Carter model and the mortality indices have tails thicker than those of a normal...

Mortality improvement has become a major issue in ratemaking for insurance companies, and ratemaking is especially difficult in Taiwan. There are two reasons for this difficulty: population size and rapid improvement in mortality. Because the history of life insurance in Taiwan is relatively...
