Even as life expectancy in many countries has continued to increase, social security and similar government programs can provide strong incentives for workers to leave the labor force when they reach the age of eligibility for benefits. Disability insurance programs can also play a significant role in the departure of older workers from the labor force, with many individuals in some countries relying on disability insurance until they are able to enter into full retirement. The sixth stage of an ongoing research project studying the relationship between social security programs and labor force participation, this volume draws on the work of an eminent group of international economists to consider the extent to which differences in labor force participation across countries are determined by the provisions of disability insurance programs. Presented in an easily comparable way, their research covers twelve countries, including Canada, Japan, and the United States, and considers the requirements of disability insurance programs, as well as other pathways to retirement.

In the past few years, the economic ramifications of aging have garnered close attention from a group of NBER researchers led by David A. Wise. In this volume, Wise and his collaborators continue to analyze a nexus of age-related issues.

This volume begins by looking at the implications of private and public personal retirement plans, focusing in particular on the impact of 401(k) programs on retirement strategies in light of potential social security reform and factors such as annuitization and on asset accumulation. Next, the often-observed relationship between health and wealth is dissected from two different perspectives and correlated with striking increases in health-care spending over the past two decades, despite the improved health of older populations. The volume concludes with an investigation of the retirement effects of various social security provisions in both U.S. and German systems.

This carefully developed collection expands the current investigative focus and broadens the dialogue on a rapidly growing area of social and economic concern.


This book investigates several important issues in the economics of aging, including the accumulation of wealth and the relationship between health and financial prosperity. Examining the changes in savings behavior and investment priorities in the United States over the past few decades, contributors to the volume point to a dramatic shift from employer-managed, defined benefit pensions to employee-controlled retirement savings plans. Further, the legislative reforms of the 1980s and the booming stock market of the 1990s did their share to influence the individual wealth accumulation patterns of Americans. These papers also explore the relationship between health status and economic status, considering factors like pension income and health, mortality, and medical care. The findings are based on evidence from the United States, Britain, South Africa, and Russia. The volume culminates with wide-ranging discussions on a number of key issues in the field, including innovations and factors that have contributed to a decline in mortality rates, the various medical advances that have benefited different groups and populations over time, and the determinants of expenditures on health.

This volume, the fourth to result from a remarkably productive collaboration between the National Bureau of Economic Research and the Japan Center for Economic Research, presents a selection of thirteen high-caliber papers addressing issues in the employment practices, labor markets, and health, benefit, and pension policies of the United States and Japan.

After an opening chapter assessing the recent ascendance of the U.S. economy, papers diverge to tackle a range of specific issues. Focusing less on international comparison than on the assembly of high-quality research, contributors hone in on a variety of individual topics. Chapters delve into issues of youth employment, participatory employment, information sharing, fringe benefits, and drug coverage in Japan, as well as the dynamics of medical savings accounts, private insurance coverage, and benefit options in the U.S.

Like previous volumes stemming from NBER/JCER collaboration, this book represents a valuable mass of empirical data on some of the most notable employment and benefits issues in each nation, information that will both anchor and provoke scholarly analysis of these topics well into the future.
