Description: Longevity insurance benefits are deferred annuities that begin payment at advanced older ages, such as at age 82. With a longevity insurance benefit, the problem of asset decumulation with uncertain life expectancy is simplified. Instead of planning for an uncertain period, retirees can plan for the fixed period from the date of their retirement to the date at which they start receiving the longevity insurance benefit. Originally, Social Security was structured as a longevity insurance benefit program, with roughly 50 percent of those entering the workforce surviving to receive the benefits. Over time, however, as life expectancy has improved, Social Security benefits have slowly transformed into benefits that most people entering the work force ultimately receive. While adding longevity insurance as a new benefit when Social Security is already facing a financing deficit would be problematic, reintroduction of a longevity insurance benefit a s part of Social Security reform package that involved benefit cuts could be an important policy innovation.
