October 2017The Children of the Missed Pill
with Tomás Rau, Sergio S. Urzúa: w23911

Our empirical strategy combines multiple sources of information and takes into account the seasonality of conceptions and the general trends of fertility, as well as the dynamics that arise after interrupting Pill's intake. Our estimates suggest that due to the price hike, the weekly birth rate increased by 4%. We show large effects on the number of children born to unmarried mothers, from mothers in their early 20's, and to primiparae women.

We use the model to estimate average treatment effects of being bullied at age 15 on several outcomes measured at age 18. We show that bullying is very costly. It increases the probability of smoking as well as the likelihood of feeling sick, depressed, stressed and unsatisfied with life. It also reduces college enrollment and increases the dislike of school. We document that differences in non-cognitive and cognitive ...
