We use temperature variation within narrowly-defined geographic and demographic cells to show that prenatal exposure to extreme heat increases the risk of maternal hospitalization during pregnancy, and that this effect is larger for black than for white mothers. At childbirth, heat-exposed...

Early term birth is defined as birth at 37 or 38 weeks gestation. While infants born early term are not considered premature, the medical literature suggests that they have an increased risk of serious adverse health outcomes compared to infants born at term (39 or 40 weeks). Despite these known...

Despite plausible mechanisms, little research has evaluated potential changes in health behaviors as a result of the Medicaid expansions of the 1980s and 1990s. In this paper, we provide the first national study of the effects of Medicaid on health behaviors for pregnant women, which is a group...

Maternity leave policies are presumed to be essential to ensure the health of pregnant workers and their unborn children. However, little is known about the optimal duration of prenatal maternity leave and existing policies are not evidence-based. We evaluate a substantial maternity leave...

Maternity leave policies are designed to safeguard the health of pregnant workers and their unborn children. However, little is known about the impact of existing policies, which are not evidence-based. We evaluate a maternity leave extension in Austria, which increased mandatory leave from 6 to...

Over the last few decades, health care services in the United States have become more geographically centralized. We study how the loss of hospital-based obstetric units in over 400 counties affect maternal and infant health via a difference-in-differences design. We find that closures lead...

We examine the impact of air pollution on infant death in California over the 1990s. Our work offers several innovations: First, many previous studies examine populations subject to far greater levels of pollution. In contrast, the experience of California in the 1990s is clearly relevant to...

This paper exploits a unique opportunity to evaluate the impact of the quality change in the labor and delivery services on maternal and infant health. Since basic medical care has been universally available in Ukraine, implementation of the Mother and Infant Health Project allows addressing...
