TRAP'd Teens: Impacts of abortion provider regulations on fertility & education (with Kelly M. Jones). IZA Discussion Paper No. 14837. Under review

Targeted regulations of abortion providers (TRAP laws) are the fastest-growing abortion restriction in the U.S. These often result in clinic closures, limiting abortion access. We study how women's exposure to these laws in adolescence affects their fertility and educational attainment. We first codify the legal history of all TRAP laws ever implemented. We then explore the impacts of TRAP laws on teen births using an event-study analysis and stacked difference-in-differences methodology to avoid issues of negative weighting inherent in two-way fixed effects approaches. Our findings indicate that teen births in states that implemented TRAP laws increased by more than 3 percent relative to changes in states without these restrictions. We offer evidence that these impacts are driven by reductions in abortion access and abortion use. We further document that adolescent exposure to TRAP laws has downstream impacts on education. We find that Black women first exposed to TRAP laws before age 18 are 2.1 percent less likely to initiate college and 5.8 percent less likely to complete college. For White women, impacts are on college completion only, are less than half as large, and are not robust.

Texas Senate Bill 8 significantly reduced travel to abortion clinics in Texas (with Martin Andersen, Chris Marsicano, and David Slusky)Frontiers in Global Women's Health, March 2023

The Dobbs v. Jackson decision by the United States Supreme Court has rescinded the constitutional guarantee of abortion across the United States. As a result, at least 13 states have banned abortion access with unknown effects. Using “Texas” SB8 law that similarly restricted abortions in Texas, we provide insight into how individuals respond to these restrictions using aggregated and anonymized human mobility data. We find that “Texas” SB 8 law reduced mobility near abortion clinics in Texas by people who live in Texas and those who live outside the state. We also find that mobility from Texas to abortion clinics in other states increased, with notable increases in Missouri and Arkansas, two states that subsequently enacted post-Dobbs bans. These results highlight the importance of out-of-state abortion services for women living in highly restrictive states.

New Evidence on the Effects of Mandatory Waiting Periods for Abortion (with Jason Lindo), NBER Working Paper 26228, Journal of Health Economics, December 2021

Beyond a handful of studies examining early-adopting states in the early 1990s, little is known about the causal effects of mandatory waiting periods for abortion. In this study, we evaluate the effects of a Tennessee law enacted in 2015 that requires women to make an additional trip to abortion providers for state-directed counseling at least 48 hours before they can obtain an abortion. Our difference-in-differences and synthetic-control estimates indicate that the introduction of the mandatory waiting period caused a 53–69 percent increase in the share of abortions obtained during the second trimester. Our analysis examining overall abortion rates is less conclusive but suggests a reduction caused by the waiting period. To put these estimates into context, we provide back-of-the-envelope calculations on the additional monetary costs that Tennessee’s MWP imposes on women seeking abortions.

Legal Access to Reproductive Control Technology, Women's Education, and Earnings Approaching Retirement Outcomes (with Jason Lindo, David Pritchard, and Hedieh Tajali), Papers and Proceedings 2020

We investigate how historical changes in contraception and abortion access impact women's long-run outcomes. We use data from the Health and Retirement Study and an identification strategy that leverages variation in exposure to legal changes in access across cohorts born in the same states during the 1960s and 1970s. Our results for educational attainment align with prior work but are not statistically significant. The results for earnings indicate increases in the probability of working in a Social Security(SS) covered job in women's 20s and 30s associated with early access to contraception and abortion, but we find no evidence of positive effects on women's earnings in their 50s.
