Recent work shows that peers affect student achievement, but the mechanisms are not well understood. I show that peer behavior is an important mechanism, perhaps more so than ability, by exploiting exogenous timing in diagnosis/treatment of ADD among peers that improves peer behavior while...

Three quarters of American children have been exposed to neighborhood violence in their lifetimes. Most of the existing research has concluded that exposure to violence leads to restricted emotional development, aggressive behavior and poor school outcomes. However, this literature fails to...

Three quarters of all violence against women is perpetrated by domestic partners. I study both the economic causes and consequences of domestic violence. I find that decreases in the male-female wage gap reduce violence against women, consistent with a household bargaining model. The...

Of the ten million uninsured children in 1996, nearly half were eligible for Medicaid, the public health insurance program for poor families, but not enrolled. In response, policy efforts to improve coverage have shifted to increasing Medicaid take-up among those already eligible rather than...

Women who give birth as teens have worse subsequent educational and labor market outcomes than women who have first births at older ages. However, previous research has attributed much of these effects to selection rather than a causal effect of teen childbearing. Despite this, there are still...

The 1940s witnessed substantial reductions in the Black-white earnings gap. We study the role that domestic WWII defense production played in reducing this gap. Exploiting variation across labor markets in the allocation of war contracts to private firms, we find that war production contracts...

All redistributive and social insurance programs trade off the potential benefits of transfers with the disincentives these programs generate. We investigate this trade-off using newly collected lifetime data for 16,000 women who applied to the Mothers' Pension Program, the first cash transfer...

We study the Civilian Conservation Corps (CCC) - the first and largest youth training program in the U.S. in operation between 1933 and 1942 - to provide the first comprehensive assessment of the short- and long-term effects of means-tested youth employment programs. We use digitized enrollee...

Economic research on the safety net has evolved significantly over time, moving away from a near exclusive focus on the negative incentive effects of means-tested assistance on employment, earnings, marriage and fertility to include examination of the potential positive benefits of such programs...

We study how advances in scientific knowledge affect the evolution of disparities in health. Our focus is the 1964 Surgeon General Report on Smoking and Health - the first widely publicized report of the negative effects of smoking on health. Using an historical dataset that includes the smoking...
