We estimate the trend in the transitory variance of male earnings in the U.S. using the Michigan Panel Study of Income Dynamics from 1970 to 2004. Using both an error components model as well as simpler but only approximate methods, we find that the transitory variance started to increase in the...

The decline in the employment-population ratios for men and women over the period 2000-2007 prior to the Great Recession represents an historic turnaround in the evolution of U.S. employment. The decline is disproportionately concentrated among the less educated and younger groups within the...

We assess the effectiveness of means-tested and social insurance programs in the United States. We show that per capita expenditures on these programs as a whole have grown over time but expenditures on some programs have declined. The benefit system in the U.S. has a major impact on poverty...

Means-tested and social insurance programs in the U.S. have been transformed over the last 25 years, with expansions in Medicare and Medicaid, the Earned Income Tax Credit, and Supplemental Security Income, and with contractions in Temporary Assistance for Needy Families. We examine the effect...

Work requirements in means-tested transfer programs have grown in importance in the U.S. and in some other countries. The theoretical literature which considers their possible optimality generally operates within a traditional welfarist framework where some function of the utility of the poor is...

A long-standing issue in the literature on education is whether marginal returns to education fall as education rises. If the population differs in its rate of return, a closely related question is whether marginal returns to higher education fall as a greater fraction of the population enrolls....

We examine whether handedness is related to performance in the labor market and, in particular, earnings. We find a significant wage effect for left-handed men with high levels of education. This positive wage effect is strongest among those who have lower than average earnings relative to those...

The Social Security Disability Insurance (SSDI) Program has long been criticized by economists for its apparent work disincentives stemming from the imposition of 100-percent tax rates on earnings. However, the program has been modified in recent years to allow recipients to keep some of their...

Existing research on the static effects of the manipulation of welfare program benefit parameters on labor supply has allowed only restrictive forms of heterogeneity in preferences. Yet preference heterogeneity implies that the marginal effects of welfare reforms on labor supply may differ in...

A long literature in economics studies differential allocations of resources to children within the family. In a study of approximately 1,600 very disadvantaged households with children in three cities in the U.S. from 1999 to 2005, significant differences in levels of food allocation, as...
