|October 2019||What to Expect When It Gets Hotter: The Impacts of Prenatal Exposure to Extreme Heat on Maternal and Infant Health|
with Ajin Lee, Maya Rossin-Slater: w26384
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 mothers are more likely to have hypertension and have longer hospital stays. For infants, fetal exposure to extreme heat leads to a higher likelihood of dehydration at birth and hospital readmission in the first year of life. Our results provide new estimates of the health costs of climate change and identify environmental drivers of the black-white maternal health gap.
|August 2017||Testing for Peer Effects Using Genetic Data|
with John Cawley, Euna Han, Edward C. Norton: w23719
Estimating peer effects is notoriously difficult because of the reflection problem and the endogeneity of peer group formation. This paper tests for peer effects in obesity in a novel way that addresses these challenges. It addresses the reflection problem by using the alter’s genetic risk score for obesity, which is a significant predictor of obesity, is determined prior to birth, and cannot be affected by the behavior of others. It addresses the endogeneity of peer group formation by examining peers who are not self-selected: full siblings. Using data from the National Longitudinal Survey of Adolescent Health, we find evidence of positive peer effects in weight and obesity; having a sibling with a high genetic predisposition raises one’s risk of obesity, even controlling for one’s own ...
