|June 2017||Long-Run Pollution Exposure and Adult Mortality: Evidence from the Acid Rain Program|
with Alan I. Barreca, Matthew Neidell: w23524
Though over 90 percent of benefits from environmental quality improvements are attributed to long-term exposure, nearly all quasi-experimental evidence on the effects of pollution on health exploits changes in short-term exposure. Quantifying long-run exposure impacts requires a lasting, exogenous change in ambient pollution. Even if the initial change in pollution is exogenous, the long-run nature allows more time for economic agents to respond to changes in pollution, resulting in endogenous pollution exposure. We estimate the effects of long-run pollution exposure on mortality among adults by exploiting the United States Acid Rain Program (ARP) as a natural experiment. The ARP, which regulated emissions from coal power plants, created a permanent change in pollution across vast distance...
|September 2011||Where Have All the Young Men Gone? Using Gender Ratios to Measure Fetal Death Rates|
with Charles F. Stoecker: w17434
Fetal health is an important consideration in the formation of health-based policy. However, a complete census of true fetal deaths is impossible to obtain. We present the gender ratio of live births as an under-exploited metric of fetal health and apply it to examine the effects of air quality on fetal health. Males are more vulnerable to side effects of maternal stress in utero, and thus are more likely to suffer fetal death due to pollution exposure. We demonstrate this metric in the context of the Clean Air Act Amendments of 1970 (CAAA) which provide a source of exogenous variation in county-level ambient total suspended particulate matter (TSPs). We find that a standard deviation increase in annual average TSPs (approximately 35 μg/m3) decreases the percentage of live birth...

|July 2011||Caution, Drivers! Children Present: Traffic, Pollution, and Infant Health|
with Christopher R. Knittel, Douglas L. Miller: w17222
Since the Clean Air Act Amendments of 1990 (CAAA), atmospheric concentration of local pollutants has fallen drastically. A natural question is whether further reductions will yield additional health benefits. We further this research by addressing two related research questions: (1) what is the impact of automobile driving (and especially congestion) on ambient air pollution levels, and (2) what is the impact of modern air pollution levels on infant health? Our setting is California (with a focus on the Central Valley and Southern California) in the years 2002-2007. Using an instrumental variables approach that exploits the relationship between traffic, ambient weather conditions, and various pollutants, our findings suggest that ambient pollution levels, specifically particulate matter, s...

|August 2008||Ability, Gender, and Performance Standards: Evidence from Academic Probation|
with Jason M. Lindo, Philip Oreopoulos: w14261
We use a regression discontinuity design to examine students' responses to the negative incentive brought on by being placed on academic probation. Consistent with a model of introducing performance standards in which agents respond differently based on ability, we find that being placed on probation at the end of the first year discourages some students from returning to school while improving the performance of those who return. Contrary to the predictions of the model when ability is known, we find that heterogeneous discouragement effects result in high ability students having a greater overall dropout rate near the cutoff than lower ability students. The result can be explained by extending the model to allow for the performance standard to also affect self confidence (ability expecta...
