Why have health care costs moderated in the last decade? Some have suggested the Great Recession alone was the cause, but health expenditure growth in the depths of the recession was nearly identical to growth prior to the recession. Nor can the Affordable Care Act (ACA) can take credit, since...

In his classic 1957 study of hybrid corn, Griliches emphasized the importance of economic incentives and profitability in the adoption of new technology, and this focus has been continued in the economics literature. But there is a distinct literature with roots in sociology emphasizing the...

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...

In the United States, health care technology has contributed to rising survival rates, yet health care spending relative to GDP has also grown more rapidly than in any other country. We develop a model of patient demand and supplier behavior to explain these parallel trends in technology growth...

There is conflicting evidence on the importance of out-of-pocket medical expenditures as a risk to financial security, particularly at older ages. We revisit this question, focusing on health care spending near the end of life using data from the Health and Retirement Study for the years...

Tax reforms are sometimes touted to have strong macroeconomic growth effects. We consider the impact of a major tax reform on the long-term growth rates of the U.S. economy using three approaches. The first approach is to examine the historical record of the U.S. economy to evaluate whether tax...

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...

One view of government fiscal policy is that it stifles dynamic economic growth through the distortionary effects of taxation and inefficient government spending.

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...

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...
