Researchers have increasingly realized the need to account for within-group dependence in estimating standard errors of regression parameter estimates. The usual solution is to calculate cluster-robust standard errors that permit heteroskedasticity and within-cluster error correlation, but...

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...

Over the last several decades, both delay of childbearing and fertility problems have become increasingly common among women in developed countries. At the same time, technological changes have made many more options available to individuals experiencing fertility problems. However, these...

A large literature has documented relationships between state clean indoor air laws (SCIALs) and smoking-related outcomes in the US. These laws vary within states over time and across venues such as schools, government buildings, and bars. Few studies, however, have evaluated whether the effects...

We examine the effects of state health insurance mandates requiring coverage of screening mammograms. We find robust evidence that mammography mandates significantly increased mammography screenings by 4.5-25 percent. Effects are larger for women with less than a high school degree in states...

A growing economics literature establishes a causal link between in utero shocks and health and human capital in adulthood. Most studies rely on extreme negative shocks such as famine and pandemics. We are the first to examine the impact of a positive and policy-driven change in economic...

This chapter provides an overview of the patchwork of U.S. food and nutrition programs, with detailed discussions of SNAP (formerly the Food Stamp Program), WIC, and the school breakfast and lunch programs. Building on Currie’s (2003) review, we document the history and goals of the programs,...

During the 30 years, the composition of white and black families in the US has changed dramatically. In 1960, less than 10% of families with children were headed by a single mother, while in 1990 more than 20% of families with children were headed by females. A large body of research has focused...

The goal of federal food and nutrition programs in the United States is to improve the nutritional well-being and health of low income families. A large body of literature evaluates the extent to which the Supplemental Program for Women Infants and Children (WIC) has accomplished this goal, but...

This paper estimates the total value that individuals derive from their state's tax-and-transfer program, and shows how this value varies by income. The paper decomposes this total value into two components: redistributive value, which is due to predictable changes in income (and family...
