July 2019The Effect of E-Cigarette Taxes on Pre-Pregnancy and Prenatal Smoking, and Birth Outcomes
with Rahi Abouk, Scott Adams, Johanna Catherine Maclean, Michael F. Pesko: w26126
We use the universe of birth records in the United States from 2013 to 2017 to examine the effect of e-cigarette taxes on pre-pregnancy smoking, prenatal smoking, and birth outcomes (birth weight, gestational length, and Apgar 5 score). We apply a differences-in-differences model to study these questions. We have two principle findings. First, e-cigarette tax adoption increases pre-pregnancy and prenatal smoking, implying that e-cigarettes and traditional cigarettes are substitutes among pregnant women. Second, in line with clinical literature suggesting that both e-cigarettes and traditional cigarettes are harmful to developing fetuses, birth outcomes are largely unchanged following adoption of an e-cigarette tax. In sum, our results suggest that e-cigarettes reduce prenatal smoking,...
April 2017The Effects of E-Cigarette Minimum Legal Sale Age Laws on Youth Substance Use
with Dhaval Dave, Michael F. Pesko: w23313
We use difference-in-differences models and individual-level data from the national and state Youth Risk Behavior Surveillance System (YRBSS) from 2005 to 2015 to examine the effects of e-cigarette Minimum Legal Sale Age (MLSA) laws on youth cigarette smoking, alcohol consumption, and marijuana use. Our results suggest that these laws increased youth smoking participation by about one percentage point, and approximately half of the increased smoking participation could be attributed to smoking initiation. We find little evidence of higher cigarette smoking persisting beyond the point at which youth age out of the laws. Our results also show little effect of the laws on youth drinking, binge drinking, and marijuana use. Taken together, our findings suggest a possible unintended effect of e-...
