In developed countries, men’s labor force participation at older ages has increased in recent years, reversing a decades-long pattern of decline. Participation rates for older women have also been rising. What explains these patterns, and the differences in them across countries? The answers to these questions are pivotal as countries face fiscal and retirement security challenges posed by longer life-spans. This eighth phase of the International Social Security project, which compares the social security and retirement experiences of twelve developed countries, documents trends in participation and employment and explores reasons for the rising participation rates of older workers. The chapters use a common template for analysis, which facilitates comparison of results across countries. Using within-country natural experiments and cross-country comparisons, the researchers study the impact of improving health and education, changes in the occupation mix, the retirement incentives of social security programs, and the emergence of women in the workplace, on labor markets. The findings suggest that social security reforms and other factors such as the movement of women into the labor force have played an important role in labor force participation trends.

Social Security Policy in a Changing Environment analyzes the changing economic and demographic environment in which social insurance programs that benefit elderly households will operate. It also explores how these ongoing trends will affect future beneficiaries, under both the current social security program and potential reform options. In this volume, an esteemed group of economists probes the challenge posed to Social Security by an aging population. The researchers examine trends in private sector retirement saving and health care costs, as well as the uncertain nature of future demographic, economic, and social trends—including marriage and divorce rates and female participation in the labor force. Recognizing the ambiguity of the environment in which the Social Security system must operate and evolve, this landmark book explores factors that policymakers must consider in designing policies that are resilient enough to survive in an economically and demographically uncertain society.

A global analysis of the effects of social security reforms on the retirement incentives and labor force trends of older workers. Employment among older men and women has increased dramatically in recent years, reversing a downward trend in the closing decades of the twentieth century. Social Security Programs and Retirement around the World examines how changing retirement incentives have reshaped labor force participation trends among older workers. The chapters feature country-specific analyses for Belgium, Canada, Denmark, France, Germany, Italy, Japan, Netherlands, Spain, Sweden, the United Kingdom, and the United States. They find that while there is significant heterogeneity across countries, the reforms of recent decades have generally reduced the implicit tax on work at older ages. These changes correlate positively with labor force participation. The studies exploit the variation in the timing and extent of reforms of retirement incentives and employ microeconometric methods to investigate whether this correlation reflects a causal relationship. Policy changes appear to have contributed to rising labor force activity, but other factors like the role of women in the labor force, improved health, and changes in private pensions likely also play important roles.

The U.S. population is aging. Social Security projections suggest that between 2013 and 2050, the population aged 65 and over will almost double, from 45 million to 86 million. One key driver of population aging is ongoing increases in life expectancy. Average U.S. life expectancy was 67 years for males and 73 years for females five decades ago; the averages are now 76 and 81, respectively. It has long been the case that better-educated, higher-income people enjoy longer life expectancies than less-educated, lower-income people. The causes include early life conditions, behavioral factors (such as nutrition, exercise, and smoking behaviors), stress, and access to health care services, all of which can vary across education and income. Our major entitlement programs - Medicare, Medicaid, Social Security, and Supplemental Security Income - have come to deliver disproportionately larger lifetime benefits to higher-income people because, on average, they are increasingly collecting those benefits over more years than others. This report studies the impact the growing gap in life expectancy has on the present value of lifetime benefits that people with higher or lower earnings will receive from major entitlement programs. The analysis presented in The Growing Gap in Life Expectancy by Income goes beyond an examination of the existing literature by providing the first comprehensive estimates of how lifetime benefits are affected by the changing distribution of life expectancy. The report also explores, from a lifetime benefit perspective, how the growing gap in longevity affects traditional policy analyses of reforms to the nation's leading entitlement programs. This in-depth analysis of the economic impacts of the longevity gap will inform debate and assist decision makers, economists, and researchers.
