The effect of population aging on aggregate labor supply in the United States
Output growth is determined by growth in labor productivity and growth in labor input. Over the past two decades, technological developments have changed how many economists think about growth in labor productivity. However, in the coming decades, the aging of the population will change how economists think about the growth in labor input in the United States. As the oldest baby boomers born in 1946 turned 50, then 55, and then 60, an important economic change has slowly surfaced: these people have become less likely to participate in the labor force. While this shift was obscured by a labor ...

Social Security's delayed retirement credit and the labor supply of older men
This paper presents estimates of the impact of Social Security's Delayed Retirement Credit on the employment rates of older men. The credit raises lifetime social security benefit payments for recipients who delay receiving benefits after age 65 and offers a rare and important test of whether labor supply incentives built in to the program can promote work at older ages. The results suggest that the increased incentives raised employment among workers over age 65. In addition, the recent increases in social security's Normal Retirement Age also appear to be pushing up labor supply.

A cohort-based model of labor force participation
The probability that an individual participates in the labor force declines precipitously beyond age 50. This feature of labor supply suggests that ongoing shifts in the age distribution of the population will put substantial downward pressure on the aggregate labor force participation rate. However, the aggregate rate is also influenced by trends within age groups. Neglecting to model both within-group influences and shifting population shares will doom any estimate of aggregate labor supply. We develop a model that identifies birth cohorts' propensities to participate, uses these ...
Working Paper
What if welfare had no work requirements? the age of youngest child exemption and the rise in employment of single mothers
The Personal Responsibility and Work Opportunity Reconciliation Act of 1996 required states to increase welfare recipient employment and participation in welfare-to-work programs. These work requirements are sometimes credited for bringing about large employment increases among single mothers. However, this paper finds that employment among single mothers who were exempted from work requirements because they had young children rose as much as that of other single mothers. The results imply that the employment gains among single mothers in the late 1990s were due to economic growth and other ...

The relocation decisions of working couples
Most prime-age married couples in the U.S. today have two labor force participants. Migration decisions are more complicated for two-earner couples than for one-earner couples because any gain from moving that accrues to one spouse must be great enough to offset any loss to the other spouse. This paper estimates the extent to which internal migration is depressed by rising earnings equality among spouses. The results indicate that couples' migration propensities are substantially lower the more equal spouses' labor incomes.
