Working Paper
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 ...

Should risky firms offer risk-free DB pensions?
We develop a simple model of pension financing to study the effects of pension risk on shareholder value. In the model, firms minimize costs, total compensation must clear the labor market, and a government pension insurer guarantees a portion of promised benefits. We find that in the absence of mispriced pension insurance, the optimal pension strategy under most specifications is to immunize all sources of market risk. Mispriced pension insurance, however, gives firms the incentive to introduce risk into their pension promises, offering an explanation for some of the observed prevalence of ...

Do households have enough wealth for retirement?
Dramatic structural changes in the U.S. pension system, along with the impending wave of retiring baby boomers, have given rise to a broad policy discussion of the adequacy of household retirement wealth. We construct a uniquely comprehensive measure of wealth for households aged 51 and older in 2004 that includes expected wealth from Social Security, defined benefit pensions, life insurance, annuities, welfare payments, and future labor earnings. Abstracting from the uncertainty surrounding asset returns, length of life and medical expenses, we assess the adequacy of wealth using two ...

Does health affect portfolio choice?
Previous studies find a strong and positive empirical connection between health status and the share of risky assets held in household portfolios. But is this relationship truly causal, in the sense that households respond to changes in health by altering their portfolio allocation, or does it simply reflect unobserved differences across households? We find that most of the variation by health is on the extensive margin of stock ownership (rather than the marginal allocation conditional on ownership), which more plausibly points to non-causal explanations. Moreover, we find that any link ...

A new look at the wealth adequacy of older U.S. households
We construct two measures of the current wealth adequacy of older U.S. households using the 1998--2006 waves of the Health and Retirement Study (HRS). The first is the ratio of "comprehensive wealth"--defined as net worth plus the expected value of future income streams--to the wealth that would be needed to generate expected poverty-line income in future years. By this measure, we find that the median older U.S. household is reasonably well situated, with a "poverty ratio" of about 3.9 in 2006. However, we find that about 18 percent of households have less wealth than would be needed to ...

Why do firms offer risky defined benefit pension plans?
Even risky pension sponsors could offer essentially riskless pension promises by contributing a sufficient level of resources to their pension trust funds and by investing those resources in fixed-income securities designed to deliver their payoffs just as pension obligations are coming due. However, almost no firm has chosen to fund its plan in this manner. We study the optimal funding choice for plan sponsors by developing a simple model of pension financing in which the total compensation offered to workers must clear the labor market. We find that if workers understand the implications of ...
