The entry of married women into the labor force is one of the most notable economic phenomena of the twentieth century. We argue that medical progress played a critical role in this process. Improved maternal health alleviated the adverse effects of pregnancy and childbirth on women's ability to...

Using data from the 2003 National Survey of College Graduates and a sample of Harvard alumnae, we study the relationship between work environment and the labor force participation of mothers. We first document a large variation in labor force participation rates across high-education fields....

This paper examines how the public policy environment in the United States affects work by new mothers following childbirth. We examine four types of policies that vary across states and affect the budget constraint in different ways. The policy environment has important effects, particularly...

Research has found that season of birth is associated with later health and professional outcomes; what drives this association remains unclear. In this paper we consider a new explanation: that children born at different times in the year are conceived by women with different socioeconomic...

In the United States, almost a third of new mothers who worked during pregnancy return to work within three months of childbirth. Current public policies in the U.S. do not support long periods of family leave after childbirth, although some states are starting to change this. As such, it is...

One of the most dramatic economic transformations of the past century has been the entry of women into the labor force. While many theories explain why this change took place, we investigate the process of transition itself. We argue that local information transmission generates changes in...

Longer life expectancy should encourage human capital accumulation, since a longer time horizon increases the value of investments that pay out over time. Previous work has been unable to determine the empirical importance of this life-expectancy effect due to the difficulty of isolating it from...

One-third of children in the United States are born to unmarried parents. A substantial number of black and Hispanic children live with a never-married mother. Children of never-married mothers are more likely to drop out of high school, repeat grades, and have behavioral problems than are...

Patients who receive more hospital treatment tend to have worse underlying health, confounding estimates of the returns to such care. This paper compares the costs and benefits of extending the length of hospital stay following delivery using a discontinuity in stay length for infants born close...

Utilizing data from the June Current Population Survey (CPS) Fertility Supplement merged with data from other months of the CPS, we describe trends in parents' employment and leave-taking after birth of a newborn and analyze the extent to which these behaviors are associated with parental leave...
