Life expectancy and old age savings
Rich people, women, and healthy people live longer. We document that this heterogeneity in life expectancy is large. We use an estimated structural model to assess the impact of life expectancy variation on the elderly?s savings. We find that the differences in life expectancy related to observable factors such as health, gender, and income 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.

The trajectory of wealth in retirement
As the baby boomers begin to retire, a great deal remains unknown about the evolution of wealth toward the end of life. In this paper, we develop a new measure of household resources that converts total financial, nonfinancial, and annuitized assets into an expected annual amount of wealth per person. We use this measure, which we call "annualized comprehensive wealth," to investigate spend-down behavior among older households in the Health and Retirement Study. Our analysis indicates that, in (real) dollar terms, the median household?s wealth declines more slowly than its remaining life ...

The tradeoff between mortgage prepayments and tax-deferred retirement savings
We show that a significant number of households can perform a tax arbitrage by cutting back on their additional mortgage payments and increasing their contributions to tax- deferred accounts (TDA). Using data from the Survey of Consumer Finances, we show that about 38% of U.S. households that are accelerating their mortgage payments instead of saving in tax-deferred accounts are making the wrong choice. For these households, reallocating their savings can yield a mean benefit of 11 to 17 cents per dollar, depending on the choice of investment assets in the TDA. ; In the aggregate, these ...

Understanding global imbalances
Two contemporary issues provide reason to focus on national saving and investment: the debate over public pensions, and pensions more generally, in all rich countries; and the large global current account imbalances, conceptually the difference between national savings and domestic investment. Are we all saving enough to provide adequate retirement income for rapidly ageing populations ? especially Americans, whose household savings seems to have disappeared altogether in 2005? And are the countries with large external deficits ? notably the United States ? mortgaging the income of future ...

Stock market participation, portfolio choice and pensions over the life-cycle
The empirical evidence on stock market participation and portfolio choice defies the predictions of standard life-cycle theory. In this paper we develop and estimate a model of portfolio choice that can account for the limited stock market participation and substantial portfolio diversification seen in the data. We present three realistic extensions to the basic framework: per period fixed costs, public pension provision, and a small chance of a disastrous event in the stock market. The estimated model is able to explain observed patterns at reasonable wealth levels, while keeping to a fairly ...

Retirement savings and decision errors: lessons from behavioral economics
Long gone are the days when most American workers could rely on their employers to manage their retirement savings. Today, most people handle their retirement portfolios themselves, gaining the right and responsibility to determine their own best strategies. Research on retirement planning suggests, however, that many fall short of consensus targets for optimal savings and investment. While part of the shortfall is explained by information gaps and income constraints, research in behavioral economics suggests that "decision errors," arising out of human tendencies such as procrastination, ...

Are firms or workers behind the shift away from DB pension plan?
One of the most striking changes in the composition of household retirement savings over the past 20 years has been the shift from defined benefit to defined contribution pension plans. Understanding the factors underlying this shift is important for determining its impact on retirement saving adequacy. Yet previous research, which has mostly focused on factors affecting all firms, such as regulation or increased longevity, has yielded little consensus. In this study we estimate the contribution of changing workforce characteristics and production environments to the shift in pension ...

Why do the elderly save? the role of medical expenses
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 ...

Accounting for the heterogeneity in retirement wealth
This paper studies a quantitative dynamic general equilibrium life-cycle model where parents and their children are linked by bequests, both voluntary and accidental, and by the transmission of earnings ability. This model is able to match very well the empirical observation that households with similar lifetime incomes hold very different amounts of wealth at retirement. Income heterogeneity and borrowing constraints are essential in generating the variation in retirement wealth among low lifetime income households, while the existence of intergenerational links is crucial in explaining the ...

Optimal retirement asset decumulation strategies: the impact of housing wealth
A considerable literature examines the optimal decumulation of financial wealth in retirement. We extend this line of research to incorporate housing, which comprises the majority of most households? non-pension wealth. ; We estimate the relationship between the returns on housing, stocks, and bonds, and simulate a variety of decumulation strategies incorporating reverse mortgages. We show that homeowner?s reversionary interest, the amount that can be borrowed through a reverse mortgage, is a surprisingly risky asset. Under our baseline assumptions we find that the average household would be ...
