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...

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...

The Panel Study of Income Dynamics (PSID) has made more contributions to the study of income volatility than any other data set in the U.S. Its record of research is truly seminal. In this paper we first present the reasons that the PSID has made such major contributions to research on the...

This paper reviews the basic theoretical models that are appropriate for analyzing different types of welfare reforms, and the related empirical literature. We first present the canonical labor supply model of a classical welfare program, and then extend this basic framework to include in-kind...

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...

This volume collects a series of essays by prominent economists on each of the major means-tested, or welfare, programs in the United States: the Medicaid, Earned Income Tax Credit, Supplemental Nutrition Assistance, Temporary Assistance for Needy Families, Supplemental Security Income,...

We provide a new examination of the incentive effects of welfare rules on family structure among low-income women by emphasizing that the eligibility and benefit rules in the AFDC and TANF programs are based more on the biological relationship between the children and any male in the household...

Unemployment rates in countries across the world are typically positively correlated with GDP. China is an unusual outlier from the pattern, with abnormally low, and suspiciously stable, unemployment rates according to its official statistics. This paper calculates, for the first time, China's...

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...
