Families, primarily female-headed minority households with children, living in high poverty public housing projects in five U.S. cities were offered housing vouchers by lottery in the Moving to Opportunity program. Four to seven years after random assignment,families offered vouchers lived in safer neighborhoods that had lower poverty rates than those of the control group not offered vouchers.We find no significant overall effects of this intervention on adult economic self-sufficiency or physical health.Mental health benefits of the voucher offers for adults and for female youth were substantial.Beneficial effects for female youth on education, risky behavior, and physical health were offset by adverse effects for male youth. For outcomes that exhibit significant treatment effects, we find, using variation in treatment intensity across voucher types and cities, that the relationship between neighborhood poverty rate and outcomes is approximately linear.
Women are currently the majority of U.S. college students and of those receiving a bachelor's degree, but were 39 percent of undergraduates in 1960. We use three longitudinal data sets of high school graduates in 1957, 1972, and 1992 to understand the narrowing of the gender gap in college and its reversal. From 1972 to 1992 high school girls narrowed the gap with boys in math and science course taking and in achievement test scores. These variables, which we term the proximate determinants, can account for 30 to 60 percent of the relative increase in women's college completion rate. Behind these changes were several others: the future work expectations of young women increased greatly between 1968 and 1979 and the age at first marriage for college graduate women rose by 2.5 years in the 1970s, allowing them to be more serious students. The reversal of the college gender gap, rather than just its elimination, was due in part to the persistence of behavioral and developmental differences between males and females.
By the mid-nineteenth century school enrollment rates in the United States exceeded those of any other nation in the world and by the early twentieth century the United States had accomplished mass education at all levels. No country was able to close the gap until the last quarter of the twentieth century. For much of its history U.S. education was spurred by a set of 'virtues,' the most important of which were public provision by small fiscally independent districts, public funding, secular control, gender neutrality, open access, a forgiving system, and an academic curriculum. The outcomes of the virtues were an enormous diffusion of educational institutions and the early spread of mass education. America borrowed its educational institutions from Europe but added to them in ways that served to enhance competition and openness. The virtues of long ago need not be the virtues of today, and they also need not have been virtuous in all places and at all times in the past. In this essay we explore the historical origins of these virtues and find that almost all were in place in the period before the American Civil War.
