Savings after Retirement: A Survey
Retired U.S. households, especially those with high income, decumulate their assets more slowly than implied by the basic life cycle model. The observed patterns of out-of-pocket medical expenses, which rise quickly with age and income during retirement, and longevity, which also rises with income, can explain a significant portion of U.S. retirement saving. However, more work is needed to disentangle these precautionary motives from other motives, such as the desire to leave bequests.
