What I learned from NLS data

A series of papers in the late 1990s started to use the NLSY79 to address selection issues in models of fertility. One line of work was on the effects of teenage childbearing on later life outcomes. While there remains debate on this issue, most researchers now agree that poor outcomes for teen mothers is driven by moderate to large selection into teen motherhood.

Why I chose NLS data

At the time, the NLSY79 focused on the right age group and had detailed and high frequency data on fertility, education, labor supply and earnings. For my particular project it had detailed data on pregnancy outcomes including miscarriages and abortions.
