We test whether students in a hybrid format of introductory microeconomics, which met once per week, performed as well as students in a traditional lecture format of the same class, which met twice per week. We randomized 725 students at a large, urban public university into the two formats, and...

We compare student academic performance in traditional twice-a-week and compressed once-a-week lecture formats in introductory microeconomics between one semester in which students were randomly assigned into the formats and another semester when students were allowed to choose their format. In...

This paper makes contributions to the estimation of health production functions and the economics of fertility control. We present the first infant health production functions that simultaneously control for self selection in the resolution of pregnancies as live births or induced abortions and...

Evaluating policy changes that occur everywhere at the same time is difficult because of the lack of a clear counterfactual. Hoping to address this problem, researchers often proxy for differential exposure using some observed characteristic in the pre-treatment period. As a cautionary tale of...

I examine whether New York State's Prenatal Care Assistance Program (PCAP) is associated with greater use of prenatal services and improved birth outcomes. PCAP is New York State's augmented prenatal care initiative that became a part of the Medicaid program after expansion in income eligibility...

Relatively high birth rates among black adolescents andunmarried women as well as inadequate access to medical care areconsidered primary reasons why the black neonatal mortality rateis almost double that of whites. Using household productiontheory, this paper examines the determinants of input...

This paper develops a method to correct for non-random measurement error in a binary indicator of illicit drugs. Our results suggest that estimates of the effect of self reported prenatal drug use on birth weight are biased upwards by measurement error -- a finding contrary to predictions of a...

Recent analyses suggest that cigarette excise taxes lower prenatal smoking. It is unclear, however, whether the association between taxes and prenatal smoking represents a decline among women of reproductive age or a particular response by pregnant women. We address this question directly with...

The 'Illegitimacy Bonus,' part of 1996 welfare reform legislation, awarded $100 million in each of five years to the five states with the greatest reduction in the nonmarital birth ratio. Three states -- Alabama, Michigan, and Washington DC -- won bonuses four or more times each, claiming nearly...

This paper examines the relationship between the legalization of abortion and subsequent decreases in crime. In a current study, researchers estimate that the legalization of abortion explains over half of the recent decline in national crime rates. The association is identified by correlating...
