Stochastic analysis in life office management: applications to large annuity portfolios

摘要

The paper deals with the riskiness analysis for a large portfolio of life annuities. By means of the limiting distribution of the present value of the portfolio, in the first part of the paper a model for evaluating the investment and the projection risks is presented. In the second part, with regard to the investment risk's effects the insolvency risk is measured considering the cumulative probability distribution function of the discounted average cost per policy.
