This paper explores how the wage and career consequences of motherhood differ by skill and timing. Past work has often found smaller or even negligible effects from childbearing for high-skill women, but we find the opposite. Wage trajectories diverge sharply for high scoring women after, but...

We study the effect of incorporating heterogeneity into default rules by examining the choice between retirement plans at a firm which transitioned from a defined benefit (DB) to a defined contribution (DC) plan. The default plan for existing employees varied discontinuously depending on their...

The current practice of measuring age as years-since-birth, both in common practice and in the law, rather than alternative measures reflecting a person's stage in the lifecycle distorts important behavior such as retirement, saving, and the discussion of dependency ratios. Two alternative...

During 2006, the Gallup Organization conducted a World Poll that used an identical questionnaire for national samples of adults from 132 countries. I analyze the data on life satisfaction (happiness) and on health satisfaction and look at their relationships with national income, age, and...

This paper examines retirement and related behavioral responses to policies that on average are actuarially neutral. Many conventional models predict that actuarially neutral policies will not affect retirement behavior. In contrast, our model allows those with high time preference rates to find...

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...

Some important novelists have written a great novel early in their careers and have produced lesser works thereafter, whereas others have improved their work gradually over long periods and have made their major contributions late in their lives. Which of these patterns a novelist follows...

This paper examines the careers of eleven leading American poets of the past century. Using the frequency with which poems are reprinted in anthologies as a measure of their importance, quantitative analysis reveals that among these poets there were two distinctly different life cycles: one...

Data from the Bureau of the Census, the Health Care Financing Administration, the NBER Tax File and the Current Population Survey are used to estimate for the elderly (ages 65 and above) consumption of health care and income available for other goods and services in 1975, 1985, and 1995....

Using transactions from fine art auctions for 42 leading American contemporary artists I estimate the relationship between the value of a painting and the artist's age at the date of its execution. The econometric estimates show that artists born before 1920 were likely to have done their most...
