Value of Longevity Pooling
The Society of Actuaries’ Pension Section has completed a research effort exploring the value of longevity pooling and its implications. This page contains links to the following materials:
- A simple, draft Excel model developed by Moshe Milevsky that presents illustrations of the value of longevity pooling. The model allows a user to produce different scenarios by inputting values for interest rates and risk aversion. Users of the model are encouraged to provide comments on its design and areas for further development. (with permission from the author)
- An accompanying document for the Excel model that describes the concepts and assumptions underlying the model’s algorithm, several numerical samples, and related information. The document has been extracted from a forthcoming book entitled “Retirement Income Recipes in R”, Moshe A. Milevsky (with permission from the author).
- A paper by Daniel Bauer summarizing literature and findings related to longevity risk pooling. The paper includes discussion of how the value of longevity risk pooling is measured and a description of potential opportunities for pooling to support increased retirement security. Readers are encouraged to review the paper’s Appendix for detailed information on the underlying life cycle model supporting measurement of the benefit of pooling.
