Over the past 100 years, life expectancies in the developed world have increased at a rate of approximately 2.5 years per decade. The enormous improvement in longevity is one of the greatest achievements of modern civilization, but, to the extent that it is unanticipated, longevity improvement can pose problems to governments and pension plans. The adverse impact of under-estimating longevity improvement is huge, especially in the current low interest rate environment where future pension and annuity liabilities are not heavily discounted. Recently, some pension providers have sought solutions to the problem of longevity risk from capital markets. They trade, with counterparties such as investment banks, securities that are linked to future longevity improvements. Since its emergence in early 2000s, the market for longevity risk securitization has developed slowly. The slow development is due partly to several important technical issues that are yet to be resolved. In this research project, the investigator will focus on some of these issues. Specifically, the objectives of this project are threefold: (1) to develop multi-population stochastic mortality models, which are useful for participants in the longevity risk market; (2) to develop methods for pricing more complicated longevity securitizations that have recently emerged; (3) to develop strategies that permit pension plans to hedge their longevity risk exposures effectively. It is expected that the results of the proposed research will accelerate the growth of the longevity risk market, facilitating the shift of longevity risk to parties who are better able to handle its financial consequences.

在过去100年中，发达世界的预期寿命以每十年约2.5岁的速度增长。寿命的巨大提高是现代文明最伟大的成就之一，但在某种程度上，寿命的提高是意料之外的，这可能会给政府和养老金计划带来问题。低估寿命改善的不利影响是巨大的，特别是在目前的低利率环境下，未来的养老金和年金负债没有大幅贴现。 最近，一些养老金提供者从资本市场寻求长寿风险问题的解决方案。他们与投资银行等交易对手交易与未来寿命改善相关的证券。自21世纪初出现以来，长寿风险证券化市场发展缓慢。发展缓慢的部分原因是几个重要的技术问题尚未解决。在本研究项目中，研究人员将重点关注其中的一些问题。具体而言，该项目有三个目标： (1)发展多人口随机死亡率模型，这对长寿风险市场的参与者是有用的; (2)为最近出现的更复杂的长寿证券化制定定价方法; (3)制定战略，使养老金计划能够有效地对冲长寿风险。 预计拟议研究的结果将加速长寿风险市场的增长，促进长寿风险转移到能够更好地处理其财务后果的各方。
