The issue of whether higher lifetime income households save a larger fraction of their income is an important factor in the evaluation of tax and macroeconomic policy. Despite an outpouring of research on this topic in the 1950s and 1960s, the question remains unresolved and has since received...

Microdata studies of household saving often find a significant group in the population with virtually no wealth, raising concerns about heterogeneity in motives for saving. In particular, this heterogeneity has been interpreted as evidence against the life-cycle model of saving. This paper...

This paper examines predictions of a life-cycle simulation model -- in which individuals face uncertainty regarding their length of life, earnings, and out-of-pocket medical expenditures, and imperfect insurance and lending markets -- for individual and aggregate wealth accumulation. Relative to...

Recent legislative proposals have included restoring Individual Retirement Accounts (IRAs) to their pre-1987 eligibility rules. Whether IRAs are simply tax windfalls with no effect on saving, or whether IRAs stimulate saving, is a crucial issue in evaluating the effectiveness of such proposals....

The efficient markets hypothesis has dominated modern research on asset prices. Asset prices and their intrinsic values differ in inefficient financial markets but difficulties in the measurement of intrinsic value greatly complicate market efficiency tests. Reflections on the measurement of...

Many critics believed that the Tax Reform Act of 1986 (TRA86) would discourage saving. Yet personal saving rates have rebounded since 1987. This rebound might have been caused by a general decline in marginal tax rates on household saving. And we estimate, at least for the 1980s, a positive...

To address the question of whether IRA5 contribute to capital formation, we use the IRS/University of Michigan taxpayer sample for income tax returns during 1980-84. By matching families across a five-year period, we can estimate the dynamic interactions of IRA purchases and other types of...

The recent appreciation in housing value can have large effects on aggregate saving. This paper uses a simulation model to show that aggregate saving will decline substantially if life cycle homeowners spend down their housing windfalls. Homeowners with a bequest motive, however, may save more...

Many observers believe current aging baby boomers are woefully unprepared for retirement. Others raise the prospect that Americans are saving too much for retirement. This paper attempts to reconcile these contrasting views using a simple life cycle model and a more sophisticated retirement...
