Assisted reproductive technology and women's choice to pursue professional careers
Sarah Kroeger & Giulia La Mattina
Journal of Population Economics, July 2017, Pages 723-769

Abstract:

We examine the impact of assisted reproductive technology on women's choice to pursue professional careers. We hypothesize that the availability of assisted reproductive technology increases the expected benefits of a professional degree by allowing women to delay childbearing in their 20s and 30s while establishing their careers, thereby reaping greater financial benefit from human capital investment. State-level timing differences in the enactment of laws which mandated infertility treatment coverage in employer-sponsored health plans allow us to exploit state, year, and cohort variation in women's ages at the time the laws are passed. These insurance mandates dramatically increase access to assisted reproductive technology. Using a triple difference strategy, we find that a mandate to cover assisted reproductive technology does increase the probability that a woman chooses to invest in a professional degree and to work in a professional career.


Political gender inequality and infant mortality in the United States, 1990-2012

Social Science & Medicine, June 2017, Pages 127-135

Abstract:

Although gender inequality has been recognized as a crucial factor influencing population health in the developing world, research has not yet thoroughly documented the role it may play in shaping U.S. infant mortality rates (IMRs). This study uses administrative data with fixed-effects and random-effects models to (1) investigate the relationship between political gender inequality in state legislatures and state infant mortality rates in the United States from 1990 to 2012, and (2) project the population level costs associated with women's underrepresentation in 2012. Results indicate that higher percentages of women in state legislatures are associated with reduced IMRs, both between states and within-states over time. According to model predictions, if women were at parity with men in state legislatures, the expected number of infant deaths in the U.S. in 2012 would have been lower by approximately 14.6% (3478 infant deaths). These findings underscore the importance of women's political representation for population health.


Malthus in the Bedroom: Birth Spacing as Birth Control in Pre-Transition England
Francesco Cinnirella, Marc Klemp & Jacob Weisdorf
Demography, April 2017, Pages 413-436

Abstract:

We use duration models on a well-known historical data set of more than 15,000 families and 60,000 births in England for the period 1540-1850 to show that the sampled families adjusted the timing of their births in accordance with the economic conditions as well as their stock of dependent children. The effects were larger among the lower socioeconomic ranks. Our findings on the existence of parity-dependent as well as parity-independent birth spacing in England are consistent with the growing evidence that marital birth control was present in pre-transitional populations.


Deciding to Wait: Partnership Status, Economic Conditions, and Pregnancy during the Great Recession
Christine Percheski & Rachel Tolbert Kimbro
Sociological Science, February 2017

Abstract:

The Great Recession was associated with reduced fertility in the United States. Many questions about the dynamics underlying this reduction remain unanswered, however, including whether reduced fertility rates were driven by decreases in intended or unplanned pregnancies. Using restricted data from the 2006-2010 National Survey of Family Growth (N = 4,630), we exploit variation in state economic indicators to assess the impact of economic conditions on the likelihood of an intended pregnancy, an unplanned pregnancy, or no pregnancy for adult women without a college education. We focus on variations by partnership and marital status. Overall, we find that worse economic conditions were predictive of a lower risk of unplanned pregnancy. Women's odds of intended pregnancy did not, however, respond uniformly to economic conditions but varied by marital status. When economic conditions were poor, married women had lower odds of intended pregnancy, whereas cohabiting women had greater odds of intended pregnancy.


Desire for and to Avoid Pregnancy During the Transition to Adulthood
Abigail Weitzman et al.
Journal of Marriage and Family, forthcoming

Abstract:

Unintended pregnancies disproportionately occur among teenage women, yet little is known about the determinants of pregnancy desire among this group. The authors use a comprehensive baseline survey and data on pregnancy desires to investigate which unmarried 18- to 20-year-old women want a pregnancy, want to avoid pregnancy, and report consistent pregnancy desire and disinclination. Variables that positively predict pregnancy desire generally negatively predict desire to avoid pregnancy. Although most young women have no desire and strong disinclination in most weeks, childhood public assistance is a strong predictor of wanting pregnancy and not wanting to avoid it. Comparing nested models suggests that the effects of childhood disadvantage operate through social environments where early pregnancy is less stigmatized. Young women in serious relationships, who are depressed, and who are not pursuing postsecondary education have more desire for pregnancy and less disinclination, but little of childhood disadvantage is mediated by these factors.


How Far Is Too Far? New Evidence on Abortion Clinic Closures, Access, and Abortions
Scott Cunningham et al.
NBER Working Paper, April 2017

Abstract:

We estimate the effect of Texas HB2, a TRAP law that shuttered nearly half of Texas' abortion clinics in late 2013. After demonstrating that pre-existing trends in abortion rates were unrelated to the changes in access caused by HB2, we implement a difference-in-difference research design to identify the effects of abortion access. Our results suggest a substantial and non-linear effect of distance to abortion services. As the distance to the nearest abortion provider increases from less than 25 miles to 25-50 miles, there is little change in rates of legally induced abortions. But an increase to 50-100 miles reduces legal abortion rates by 16 percent, an increase to 100-200 miles reduces abortion rates by 32 percent, and an increase to 200 or more miles reduces abortion rates by 47 percent. We also introduce a proxy for congestion that predicts additional reductions in abortion rates as fewer clinics serve more women.
