NLS user since 2002
I've used data from the NLS to study the effects of marriage and fertility, as well as access to contraceptives, on lifecycle educational and career outcomes for women. These factors have important effects on women's hours worked and wages for decades following the timing of initial marriage and motherhood. One key finding is that the timing of motherhood matters and that each year of delay leads to almost 10% higher earnings.
The NLS has several unique features that enabled my research. First, is the combination of detailed information about family and career outcomes about a large and representative group of women. This includes information about contraceptive use and miscarriages that were crucial to my analytical approach. Second, the NLS follows the women over several decades, enabling my study of career outcomes and of changes over the lifecycle. Third, the NLS includes multiple waves of cohorts that allow for comparisons in how family and work interactions have changed over time.
