This paper constructs a rich model of saving for retired single people. Our framework allows for bequest motives and heterogeneity in medical expenses and life expectancies. We estimate the model using AHEAD data and the method of simulated moments. The data show that out-of-pocket medical expenses rise quickly with both age and permanent income. For many elderly people the risk of living long and requiring expensive medical care is a more important driver of old age saving than the desire to leave bequests. Social insurance programs such as Medicaid rationalize the low asset holdings of the poorest. These government programs, however, also benefit the rich because they insure them against their worst nightmares about their very old age: either not being able to afford the medical care t...

Rich people, women, and healthy people live longer. We document that this heterogeneity in life expectancy is large, and we use an estimated structural model to assess its effect on the elderly's saving. We find that the differences in life expectancy related to observable factors such as income, gender, and health have large effects on savings, and that these factors contribute by similar amounts. We also show that the risk of outliving one's expected lifespan has a large effect on the elderly's saving behavior.
