College opportunity and teen fertility: Evidence from Ser Pilo Paga in Colombia

We study the effects of an increase in post-secondary educational opportunities on teen fertility by exploiting policy-induced variation from Ser Pilo Paga (SPP), a generous college financial aid program in Colombia that dramatically expanded college opportunities for low-income students. Our preferred empirical approach uses a triple difference design that leverages variation in the share of female students eligible for the program across municipalities and the fact that the introduction of SPP should not affect the education and fertility decisions of older women not targeted by the program. We find that after the introduction of SPP, fertility rates for women aged 15–19 years old decreased in more affected municipalities by about 6 percent relative to less affected municipalities. This effect accounts for approximately one-fourth of the overall decrease in teen fertility observed in the years following the program’s announcement. Our results suggest that increasing economic opportunities through expanding college access can contribute to lowering teen fertility rates.
