A Computationally Efficient Algorithm for Estimating the Distribution of Future Annuity Values under Interest-Rate and Longevity Risks
نویسندگان
چکیده
This paper proposes a computationally efficient algorithm for quantifying the impact of interest-rate risk and longevity risk on the distribution of annuity values in the distant future. The algorithm simulates the state variables out to the end of the horizon period and then uses a Taylor series approximation to compute approximate annuity values at the end of that period, thereby avoiding a computationally expensive ‘simulation-within-simulation’ problem. Illustrative results suggest that annuity values are likely to rise considerably, but are also quite uncertain. These findings have some unpleasant implications for defined contribution pension plans. JEL Classification Numbers: G23, C15, C53

متن کاملAnnuity Product Valuation and Risk Measurement under Correlated Financial and Longevity Risks
Longevity risk is a non-diversifiable risk and regarded as a pressing socio-economic challenge of the century. Its accurate assessment and quantification is therefore critical to enable pensionfund companies provide sustainable old-age security and maintain a resilient global insurance market. Fluctuations and a decreasing trend in mortality rates, which give rise to longevity risk, as well as ...
متن کاملScale of Longevity Risks for Pension and Life Annuity Providers
Improved longevity is a human triumph. But improved longevity, when it occurs among those who are no longer economically productive, has a cost. Persistent decrease in mortality rates has become a major concern of annuity and pension providers, especially mortality improvements for post-retirement ages which have significant financial impact as far as survival benefits are concerned. There are ...
متن کاملAn EM Algorithm for Estimating the Parameters of the Generalized Exponential Distribution under Unified Hybrid Censored Data
The unified hybrid censoring is a mixture of generalized Type-I and Type-II hybrid censoring schemes. This article presents the statistical inferences on Generalized Exponential Distribution parameters when the data are obtained from the unified hybrid censoring scheme. It is observed that the maximum likelihood estimators can not be derived in closed form. The EM algorithm for computing the ma...
متن کاملSOME COMPUTATIONAL RESULTS FOR THE FUZZY RANDOM VALUE OF LIFE ACTUARIAL LIABILITIES
The concept of fuzzy random variable has been applied in several papers to model the present value of life insurance liabilities. It allows the fuzzy uncertainty of the interest rate and the probabilistic behaviour of mortality to be used throughout the valuation process without any loss of information. Using this framework, and considering a triangular interest rate, this paper develops closed...
