This paper investigates how increases in the level of maximum earnings subject to the Social Security payroll tax have affected Social Security benefits and taxes. The analysis uses data from the Health and Retirement Study to ask how different the present value of own benefits and taxes would...

In theory, improvements in healthy life expectancy should generate increases in the average age of retirement, with little effect on savings rates. In many countries, however, retirement incentives in social security programs prevent retirement ages from keeping pace with changes in life...

Population aging is primarily the result of past declines in fertility, which produced a decades long period in which the ratio of dependents to working age adults was reduced. Rising old-age dependency in many countries represents the inevitable passing of this "demographic dividend." Societies...

We use a sufficient statistic approach to quantify the general equilibrium effects of population aging on wealth accumulation, expected asset returns, and global imbalances. Combining population forecasts with household survey data from 25 countries, we measure the compositional effect of aging:...

Using a highly stylized dynamic microsimulation model, we project the labor force of the United States up to the year 2060 and contrast these projections with projections for Germany to assess differential effects on outcomes The projections are consistent with the U S Census Bureau's and...

The U.S. and other western economies are experiencing dramatic changes in growth and age structure of their populations. Fluctuations in birth rates are the most important determinants of these changes in the post war period. This paper examines the dynamic effects of baby "booms" and...

The share of the population aged 60 and over is projected to increase in nearly every country in the world during 2005-2050. Population ageing will tend to lower both labor-force participation and savings rates, thereby raising concerns about a future slowing of economic growth. Our calculations...

The extent of the demographic changes in Europe is dramatic and will deeply affect future labor, financial and goods markets. The expected strain on public budgets and especially social security has already received prominent attention, but aging poses many other economic challenges that...

Government policies that are based on age do not adjust to the fact that a given age is associated with a higher remaining life expectancy and lower mortality risk relative to earlier time periods due to improvements in mortality. We examine four possible methods for adjusting the eligibility...

With rapidly declining fertility and increased longevity the age structure of the labor force in developing countries has changed rapidly. Changing relative supply of workers by age group, and by educational attainment, can have profound effects on labor costs. Their impacts on earnings have...
