Mother's Education and the Intergenerational Transmission of Human Capital: Evidence from College Openings

We examine the effect of maternal education on birth outcomes using Vital Statistics Natality data for 1970 to 1999. We also assess the importance of four channels through which maternal education may improve birth outcomes: use of prenatal care, smoking, marriage, and fertility. In an effort to account for the endogeneity of educational attainment, we use data about the availability of colleges in the womans county in her seventeenth year as an instrument for maternal education. We find that higher maternal education improves infant health, as measured by birth weight and gestational age. It also increases the probability that a new mother is married, reduces parity, increases use of prenatal care, and reduces smoking, suggesting that these may be important pathways for the ultimate effect on health. Our results add to the growing body of literature which suggests that estimates of the returns to education which focus only on increases in wages understate the total return.

Human Capital Development Before Age Five

This chapter seeks to set out what economists have learned about the effects of early childhood influences on later life outcomes, and about ameliorating the effects of negative influences. We begin with a brief overview of the theory which illustrates that evidence of a causal relationship between a shock in early childhood and a future outcome says little about whether the relationship in question is biological or immutable. We then survey recent work which shows that events before five years old can have large long term impacts on adult outcomes. Child and family characteristics measured at school entry do as much to explain future outcomes as factors that labor economists have more traditionally focused on, such as years of education. Yet while children can be permanently damaged at this age, an important message is that the damage can often be remediated. We provide a brief overview of evidence regarding the effectiveness of different types of policies to provide remediation. We conclude with a list of some of the many outstanding questions for future research.

Longer Term Effects of Head Start

Little is known about the long-term effects of participation in Head Start. This paper draws on unique non-experimental data from the Panel Study of Income Dynamics to provide new evidence on the effects of participation in Head Start on schooling attainment, earnings, and criminal behavior. Among whites, participation in Head Start is associated with a significantly increased probability of completing high school and attending college, and we find some evidence of elevated earnings in ones early twenties. African Americans who participated in Head Start are significantly less likely to have been charged or convicted of a crime. The evidence also suggests that there are positive spillovers from older children who attended Head Start to their younger siblings.

Health Insurance Eligibility, Utilization of Medical Care, and Child Health

The poor health status of children in the U.S. relative to other industrialized nations has motivated recent efforts to extend insurance coverage to underprivileged children. There is little past evidence that extending eligibility for public insurance to previously ineligible groups will increase health status or even utilization of medical resources. Using data from the Current Population Survey, the National Health Interview Survey, and state-level data on child mortality, we examine the utilization and health effects of eligibility for public insurance. Our models are identified by the recent expansions of the Medicaid program to low income children. We find that these expansions roughly doubled the fraction of children eligible for Medicaid between 1984 and 1992; by 1992, almost 1/3 of all children were eligible. But takeup of these expansions was much less than full even among otherwise uninsured children. Despite this takeup problem, we find that eligibility for Medicaid significantly increased the utilization of medical care along a number of dimensions. Medicaid eligibility was associated with large increases in care delivered in physicians offices, although there was some increase in care in hospital settings as well. While there was no effect of eligibility on parentally-assessed subjective health measures, we do find notable reductions in child mortality. Finally, we find that rising Medicaid eligibility is associated with reductions in racial disparities in the number of visits and in child disparities in the site at which care is delivered.

Saving Babies: The Efficacy and Cost of Recent Changes in the Medicaid Eligibility of Pregnant Women

A key question for health care reform in the United States is whether expanded health insurance eligibility will lead to improvements in health outcomes. We address this question in the context of the dramatic changes in Medicaid eligibility for pregnant women that took place between 1979 and 1992. We build a detailed simulation model of each states Medicaid policy during this era and use this model to estimate (1) the effect of changes in the rules on the fraction of women eligible for Medicaid coverage in the event of pregnancy and (2) the effect of Medicaid eligibility changes on birth outcomes in aggregate Vital Statistics data. We have three main findings. First, the changes did dramatically increase the Medicaid eligibility of pregnant women, but did so at quite differential rates across the states. Second, the changes lowered the incidence of infant mortality and low birth weight; we estimate that the 30-percentage-point increase in eligibility among 15-44-year-old women was associated with a decrease in infant mortality of 8.5 percent. Third, earlier, targeted changes in Medicaid eligibility, which were restricted to specific low-income groups, had much larger effects on birth out-comes than broader expansions of eligibility to women with higher income levels. We suggest that the source of this difference is the much lower take-up of Medicaid coverage by individuals who became eligible under the broader eligibility changes. Even the targeted changes cost the Medicaid program

Long-Term Consequences of Child Abuse and Neglect on Adult Economic Well-Being

Biology as Destiny? Short and Long-Run Determinants of Intergenerational Transmission of Birth Weight

Child abuse and neglect represent major threats to child health and well-being; however, little is known about consequences for adult economic outcomes. Using a prospective cohort design, court substantiated cases of childhood physical and sexual abuse and neglect during 1967—1971 were matched with nonabused and nonneglected children and followed into adulthood (mean age 41). Outcome measures of economic status and productivity were assessed in 2003—2004 (N = 807). Results indicate that adults with documented histories of childhood abuse and/or neglect have lower levels of education, employment, earnings, and fewer assets as adults, compared to matched control children. There is a 14% gap between individuals with histories of abuse/neglect and controls in the probability of employment in middle age, controlling for background characteristics. Maltreatment appears to affect men and women differently, with larger effects for women than men. These new findings demonstrate that abused and neglected children experience large and enduring economic consequences.

Sharing the Costs: The Impact of Trade Reform on Capital and Labor in Morocco

We use a unique data set of California births to ask whether intergenerational correlations in health contribute to the perpetuation of economic status. We find that if a mother was low birth weight, her child is significantly more likely to be low birth weight, even when we compare mothers who are sisters. Second, the intergenerational transmission of low birth weight is stronger for mothers in high poverty zip codes. Third, low birth weight affects proxies for later socioeconomic status. Fourth, these effects are stronger for women born in high poverty zip codes.

The association between pregnancy weight gain and birthweight: a within-family comparison

We examine the impact of recent trade reforms. Although employment in the average private sector manufacturing firm was unaffected, there were significant employment losses to exporters and highly affected firms. Parastatals increased employment by hiring low‐paid temporary workers. Many firms did not adjust wages or employment. We examine two possible explanations. First, barriers to labor market mobility could have impeded adjustment. Second, we develop a model of labor demand which allows for imperfect competition and endogenous technological change. Our results suggest that although labor markets were flexible, many firms cut profit margins and raised productivity rather than reducing employment.

Are public housing projects good for kids

BACKGROUND Excessive weight gain during pregnancy seems to increase birthweight and the offsprings risk of obesity later in life. However, this association might be confounded by genetic and other shared effects. We aimed to examine the association between maternal weight gain and birthweight using state-based birth registry data that allowed us to compare several pregnancies in the same mother. METHODS In this population-based cohort study, we used vital statistics natality records to examine all known births in Michigan and New Jersey, USA, between Jan 1, 1989, and Dec 31, 2003. From an initial sample of women with more than one singleton birth in the database, we made the following exclusions: gestation less than 37 weeks or 41 weeks or more; maternal diabetes; birthweight less than 500 g or more than 7000 g; and missing data for pregnancy weight gain. We examined how differences in weight gain that occurred during two or more pregnancies for each woman predicted the birthweight of her offspring, using a within-subject design to reduce confounding to a minimum. FINDINGS Our analysis included 513 501 women and their 1 164 750 offspring. We noted a consistent association between pregnancy weight gain and birthweight (β 7·35, 95% CI 7·10-7·59, p<0·0001). Infants of women who gained more than 24 kg during pregnancy were 148·9 g (141·7-156·0) heavier at birth than were infants of women who gained 8-10 kg. The odds ratio of giving birth to an infant weighing more than 4000 g was 2·26 (2·09-2·44) for women who gained more than 24 kg during pregnancy compared with women who gained 8-10 kg. INTERPRETATION Maternal weight gain during pregnancy increases birthweight independently of genetic factors. In view of the apparent association between birthweight and adult weight, obesity prevention efforts targeted at women during pregnancy might be beneficial for offspring.
