The Timing of Teenage Births: Estimating the Effect on High School Graduation and Later Life Outcomes
January 2016
Working Paper Number:
CES-16-39R
We examine the long-term outcomes for a population of teenage mothers who give birth to their children around the end of their high school year. We compare the mothers whose high school education was interrupted by childbirth, because the child was born before her expected graduation date to mothers who did not experience the same disruption to their education. We find that mothers who give birth during the school year are seven percent less likely to graduate from high school, are less likely to be married, and have more children than their counterparts who gave birth just a few months later. The labor market outcomes for these two sets of teenage mothers are not statistically different, but with a lower likelihood of marriage and more children, the households of the treated mothers are more likely to fall below the poverty threshold. While differences in educational attainment have narrowed over time, the differences in labor market outcomes and family structure have remained stable.

DOES FAMILY PLANNING INCREASE CHILDREN'S OPPORTUNITIES?
EVIDENCE FROM THE WAR ON POVERTY AND THE EARLY YEARS OF TITLE X
January 2016
Working Paper Number:
CES-16-29
This paper examines the relationship between parents' access to family planning and the economic resources of the average child. Using the county-level introduction of U.S. family planning programs between 1964 and 1973, we find that children born after programs began had 2.5% higher household incomes. They were also 7% less likely to live in poverty and 11% less likely to live in households receiving public assistance. Even with extreme assumptions about selection, these estimates are large enough to imply that family planning programs directly increased children's resources, including increases in mothers' paid work and increased childbearing within marriage.

Selection and Specialization in the Evolution of Marriage Earnings Gaps
October 2015
Working Paper Number:
CES-15-36
We examine changes in marriage and earnings patterns across four cohorts born between 1936 and 1975, using data from a series of Survey of Income and Program Participation panels linked to administrative data on earnings. We find that for both men and women, marriage has become increasingly positively associated with education and earnings potential. We compare ordinary least squares (OLS) and fixed effect (FE) estimates of the earnings differential associated with marriage. We find that the marriage earnings gap fell for women in fixed-effect estimates implying that the impact of specialization has diminished over time. We also find that increasingly positive selection into marriage means that OLS estimates overstate the reduction in the marriage earnings gap. While our findings imply that marriage is no longer associated with lower earnings among women without minor children in our most recent cohort, the motherhood gap remains large. Among men, we find that the marriage premium actually increases for more recent birth cohorts in fixed-effects regressions.

Is there an Advantage to Working? The Relationship between Maternal Employment and Intergenerational Mobility
September 2015
Working Paper Number:
CES-15-27
We investigate the question of whether investing in a child's development by having a parent stay at home when the child is young is correlated with the child's adult outcomes. Specifically, do children with stay-at-home mothers have higher adult earnings than children raised in households with a working mother? The major contribution of our study is that, unlike previous studies, we have access to rich longitudinal data that allows us to measure both the parental earnings when the child is very young and the adult earnings of the child. Our findings are consistent with previous studies that show insignificant differences between children raised by stay-at-home mothers during their early years and children with mothers working in the market. We find no impact of maternal employment during the first 5 years of a child's life on earnings, employment, or mobility measures of either sons or daughters. We do find, however, that maternal employment during children's high school years is correlated with a higher probability of employment as adults for daughters and a higher correlation between parent and daughter earnings ranks.

Trends in Earnings Inequality and Earnings Instability among U.S. Couples: How Important is Assortative Matching?
January 2015
Working Paper Number:
CES-15-04
We examine changes in inequality and instability of the combined earnings of married couples over the 1980-2009 period using two U.S. panel data sets: Social Security earnings data matched to Survey of Income and Program Participation panels (SIPP-SSA) and the Panel Study of Income Dynamics. Relative to male earnings inequality, the inequality of couples' earnings is both lower in levels and rises by a smaller amount. We also find that couples' earnings instability is lower in levels compared to male earnings instability and actually declines in the SIPP-SSA data. While wives' earnings played an important role in dampening the rise in inequality and year-to-year variation in resources at the family level, we find that marital sorting and coordination of labor supply decisions at the family level played a minor role. Comparing actual couples to randomly paired simulated couples, we find very similar trends in earnings inequality and instability.

FIFTY YEARS OF FAMILY PLANNING:
NEW EVIDENCE ON THE LONG-RUN EFFECTS OF INCREASING ACCESS TO CONTRACEPTION
February 2014
Working Paper Number:
CES-14-15
This paper assembles new evidence on some of the longer-term consequences of U.S. family planning policies, defined in this paper as those increasing legal or financial access to modern contraceptives. The analysis leverages two large policy changes that occurred during the 1960s and 1970s: first, the interaction of the birth control pill's introduction with Comstock-era restrictions on the sale of contraceptives and the repeal of these laws after Griswold v. Connecticut in 1965; and second, the expansion of federal funding for local family planning programs from 1964 to 1973. Building on previous research that demonstrates both policies' effects on fertility rates, I find suggestive evidence that individuals' access to contraceptives increased their children's college completion, labor force participation, wages, and family incomes decades later.

A Dynamic Structural Model of Contraceptive Use and Employment Sector Choice for Women in Indonesia
September 2010
Working Paper Number:
CES-10-28
This research investigates the impact of the Indonesian family planning program on the labor force participation decisions and contraceptive choices of women. I develop a discrete choice dynamic structural model, where each married woman in every period makes joint choices regarding the method of contraceptive used and the sector of employment in which to work in order to maximize her expected discounted lifetime utility function. Each woman obtains utility from pecuniary sources, nonpecuniary sources, and choice-specific time shocks. In addition to the random shocks, there is uncertainty in the model as a woman can only imperfectly control her fertility. Dynamics in the model are captured by several forms of state and duration dependence. Women in this model make different choices due to different preferences, differences in observable characteristics, and realization of uncertainty. The choices made by a woman depend on the compatibility between raising children and the sector of employment (including wages). While making decisions regarding contraceptive use, a woman considers the trade-off between costs (monetary and nonmonetary) of having a child and the benefits from having one. The primary source of data for this study is the first wave of the Indonesia Family Life Survey (IFLS 1), a retrospective panel. In my research, I use the geographic expansion and the changing nature of the Indonesian family planning program as sources of exogenous variation to identify the parameters of the structural model. I estimate the model using maximum likelihood techniques with data from IFLS 1 for the periods 1979-1993. Structural model estimates indicate that informal sector jobs offer greater compatibility between work and childcare. Parameter estimates indicate that choices of contraception method and employment sector vary by exogenous characteristics.

Transitions in Welfare Participation and Female Headship
February 2004
Working Paper Number:
CES-04-01
This study uses data from the 1990, 1992, 1993, and 1996 panels of the Survey of Income and Program Participation to examine how welfare policies and local economic conditions contribute to women's transitions into and out of female headship and into and out of welfare participation. It also examines whether welfare participation is directly associated with longer spells of headship. The study employs a simultaneous hazards approach that accounts for unobserved heterogeneity in all of its transition models and for the endogeneity of welfare participation in its headship model. The estimation results indicate that welfare participation significantly reduces the chances of leaving female headship. The estimates also reveal that more generous welfare benefits contribute indirectly to headship by increasing the chances that mothers will enter welfare. More generous Earned Income Tax Credit benefits are associated with longer spells of headship, nonheadship, and welfare participation and nonparticipation. Other measures of welfare policies, including indicators for the adoption of welfare waivers and the implementation of Temporary Assistance for Needy Families programs, are generally not significantly associated with headship or welfare receipt. Better economic opportunities are estimated to increase headship but reduce welfare participation among unmarried mothers.

The Impact of Welfare Waivers on Female Headship Decisions
February 2003
Working Paper Number:
CES-03-03
While much of the focus of recent welfare reforms has been on moving recipients from welfare to work, many reforms were also directed at affecting decisions about living arrangements, pregnancy, marriage and cohabitation. This paper focuses on women's decisions to become or remain unmarried mothers, that is, female heads of families. We assess the impact of welfare reform waivers on those decisions while controlling for confounding local economic and social contextual conditions. We pool the 1990, 1992, and 1993 panels of the Survey of Income and Program Participation (SIPP) which span the calendar time when many states began adopting welfare waivers. For its descriptors of local labor market conditions, the project uses skill specific measures of wages and employment opportunities for counties. We estimate models for levels of female headship and proportional hazard models for entry and exit from female headship. In the hazards, we employ stratified Cox partial likelihood methods and investigate the use of state fixed effects or state stratified hazard models to control for unmeasured state influences. Based on data through 1995, we find limited evidence that workencouraging waivers had a beneficial effect by reducing female headship of families. We find little evidence that family caps, teenage coresidence requirements or termination limits will reduce the number of single-parent families.

The Relationship of Personal and Neighborhood Characteristics to Immigrant Fertility
August 2002
Working Paper Number:
CES-02-20
We find that fertility varies by immigrant generation, with significant declines between the first and subsequent generations for groups with large immigrant population. However, we find that personal characteristics--such as educational attainment, marital status, and income levels--are much more important than immigrant generation in understanding fertility outcomes. In fact, generations are not independently important once these personal characteristics are controlled for. We maintain that declining fertility levels among the descendants of Mexican and Central American immigrants are primarily the result of higher educational attainment levels, lower rates of marriage, and lower poverty. For example, a four-year increase in educational attainment decreases children ever born (CEB) by half a child. We conclude that immigrant generation serves as a proxy for changes in other personal characteristics that decrease fertility. Neighborhood characteristics have some bearing on fertility, but the correlations are relatively weak. Among Mexican and Central American immigrants and their descendants, the most consistent predictor of children ever born (CEB) at the neighborhood level is the percentage of Hispanic adults. However, no neighborhood characteristics bear any statistical relationship to current fertility, the measure that emphasizes recent births. This pattern of evidence suggests that the observed relationships between neighborhood characteristics and fertility are based on selection into the neighborhood rather than on neighborhood influences as such.
