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, rising 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 argues...

The question of whether higherlifetime income households save a larger fraction of their income was the subject of much debate in the 1950s and 1960s, and while not resolved, it remains central to the evaluation of tax and macroeconomic policies. We resolve this long-standing question using new...

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...
