In this paper, we assess whether welfare reform affects earnings only through mean impacts that are constant within but vary across subgroups. This is important because researchers interested in treatment effect heterogeneity typically restrict their attention to estimating mean impacts that are...

Labor supply theory predicts systematic heterogeneity in the impact of recent welfare reforms on earnings, transfers, and income. Yet most welfare reform research focuses on mean impacts. We investigate the importance of heterogeneity using random-assignment data from Connecticut's Jobs First...

Labor market outcomes of welfare reform have been the subject of extensive research by economists, but there has been relatively little work on living arrangements, which was an important focus of reformers. Our research fills that gap by using data from the March CPS to examine the impacts of...

We investigate the relationship between welfare reform and health insurance, health care utilization, and self-reported measures of health status for women aged 20-45, using nationally representative data from the Behavioral Risk Factor Surveillance System. We present estimates from both...

A large literature has been concerned with the impacts of recent welfare reforms on income, earnings, transfers, and labor-force attachment. While one strand of this literature relies on observational studies conducted with large survey-sample data sets, a second makes use of data generated by...

Much attention has been given to the large increase in safety net spending, particularly in Unemployment Insurance and Food Stamp spending, during the Great Recession. In this paper we examine the relationship between poverty, the social safety net, and business cycles historically and test...

This study provides the first comprehensive analysis of the distributional effects of Head Start, using the first national randomized experiment of the Head Start program (the Head Start Impact Study). We examine program effects on cognitive and non-cognitive outcomes and explore the...

The cash and near cash safety net in the U.S. has undergone a dramatic transformation in the past fifteen years. Federal welfare reform has led to the "elimination of welfare as we know it" and several tax reforms have substantially increased the role of "in-work"' assistance. In 2010, we spent...

We use quantile treatment effects estimation to examine the consequences of a school voucher experiment across the distribution of student achievement. In 1997, the School Choice Scholarship Foundation granted $1,400 private school vouchers to a randomly-selected group of low-income New York...

We review the existing literature about the effects of the Medicaid program. We first describe the program's structure and how it has changed over time. We then discuss findings on coverage, crowd out, take-up and health. Finally, we look at effects of the program on non-health outcomes such as...
