February 2014Particulate Pollution and the Productivity of Pear Packers
with Tom Chang, Joshua Graff Zivin, Matthew Neidell: w19944
We study the effect of outdoor air pollution on the productivity of indoor workers at a pear-packing factory. We focus on fine particulate matter (PM2.5), a harmful pollutant that easily penetrates indoor settings. We find that an increase in PM2.5 outdoors leads to a statistically and economically significant decrease in packing speeds inside the factory, with effects arising at levels well below current air quality standards. In contrast, we find little effect of PM2.5 on hours worked or the decision to work, and little effect of pollutants that do not travel indoors, such as ozone. This effect of outdoor pollution on the productivity of indoor workers suggests a thus far overlooked consequence of pollution. Back-of-the-envelope calculations suggest that nationwide reductions in PM2.5 fr...
July 2013Public Health Insurance, Labor Supply, and Employment Lock
with Craig Garthwaite, Matthew J. Notowidigdo: w19220
We study the effect of public health insurance eligibility on labor supply by exploiting the largest public health insurance disenrollment in the history of the United States. In 2005, approximately 170,000 Tennessee residents abruptly lost public health insurance coverage. Using both across- and within-state variation in exposure to the disenrollment, we estimate large increases in labor supply, primarily along the extensive margin. The increased employment is concentrated among individuals working at least 20 hours per week and receiving private, employer-provided health insurance. We explore the dynamic effects of the disenrollment and find an immediate increase in job search behavior and a steady rise in both employment and health insurance coverage following the disenrollment. Our res...
February 2012Liquidity Constraints and Consumer Bankruptcy: Evidence from Tax Rebates
with Matthew J. Notowidigdo, Jialan Wang: w17807
This paper estimates the extent to which legal fees prevent liquidity-constrained households from declaring bankruptcy. To do so, it studies how the 2001 and 2008 tax rebates affected consumer bankruptcy filings. We exploit the randomized timing of the rebate checks and estimate that the rebates caused a significant, short-run increase in consumer bankruptcies in both years, with larger effects in 2008 when the rebates were more generous and more widely distributed. Using hand-collected data from individual bankruptcy petitions, we document that the rebates caused an increase in the average liabilities and the liabilities-to-income ratios of filers.
March 2010The Effect of Health Insurance Coverage on the Use of Medical Services
with Michael Anderson, Carlos Dobkin: w15823
Substantial uncertainty exists regarding the causal effect of health insurance on the utilization of care. Most studies cannot determine whether the large differences in healthcare utilization between the insured and the uninsured are due to insurance status or to other unobserved differences between the two groups. In this paper, we exploit a sharp change in insurance coverage rates that results from young adults “aging out” of their parents’ insurance plans to estimate the effect of insurance coverage on the utilization of emergency department (ED) and inpatient services. Using the National Health Interview Survey (NHIS) and a census of emergency department records and hospital discharge records from seven states, we find that aging out results in an abrupt 5 to 8 percentage point reduct...
