Delaying the bell: the effects of longer school days on adolescent motherhood in Chile

We analyze the effect of a Chilean school reform that lengthened the school day from half to full-day shifts on the likelihood that adolescent girls become mothers. By increasing the number of hours spent in school, the reform curtails opportunities to engage in risky sexual behaviors. Using Chile's socio-economic household surveys and administrative data from the Ministry of Education from 19902006, we exploit the exogenous time and regional variation in the implementation of the reform to identify the effects of increased education and adult supervision on the likelihood that adolescent girls become mothers. We find that access to full-day schools reduces the probability of becoming an adolescent mother among poor families and in urban areas: an increase in full-day municipal enrollment of 20% reduces the likelihood of teen motherhood by 5%

Adolescent motherhood and secondary schooling in Chile

We analyze the determinants of adolescent motherhood and its subsequent effect on high school attendance and completion in Chile. Using eight rounds of household surveys, we find that adolescents who were born to teen mothers, those that live in poor households and in single-mother families, are more likely to have children, while access to full-time high schools reduces the likelihood of motherhood. We then estimate the effect of adolescent motherhood on the probability of high school attendance and completion. Using an instrumental variables approach to control for possible endogeneity between teen pregnancy and schooling, we find that being a mother reduces the probability of high school attendance and completion by 24 to 37 percent, making it the most important determinant of high school desertion, which implies that policies aimed at reducing early childbearing will have immediate, important effects on their school attainments

Household choices of child labor and schooling: a simple model with application to Brazil

This paper develops and estimates a simple structural model of household decisions regarding child labor and schooling. We argue that part of the conflicting results from the previous literature related to the effect of improvements in economic conditions on child labor derives from the different income and substitution effects implicit in different types of income variation. Our model leads to an empirical specification where income and substitution effects can be clearly identified. We apply our model to Brazil and use agricultural shocks to local economic activity (coffee and overall agricultural production) to distinguish between the effects of increases in household income and increases in the opportunity cost of children's time. The results show that higher parental wages and household wealth are associated with lower child labor and higher school attendance. Nevertheless, conditional on family income and socioeconomic status, exogenous temporary increases in local economic activity are associated with increased opportunity cost of children's time and, therefore, higher child labor and lower schooling. The results reconcile economic theory with seemingly contradictory evidence from the previous empirical literature

Risky behavior among youth: Incapacitation effects of school on adolescent motherhood and crime in Chile

We analyze the effect of a Chilean school reform that lengthened the school day from half to full-day shifts on the likelihood that adolescents engage in risky behaviors. By increasing the number of hours spent in school, the reform curtails opportunities to engage in risky behaviors that may lead to motherhood and crime. We exploit the exogenous time and regional variations of the reform's implementation to identify the effects of adult supervision on the likelihood that adolescent girls become mothers, and on municipal juvenile crime rates. We find that access to full-day schools reduces the probability of becoming an adolescent mother among poor families and in urban areas, and that the reform reduced youth crime.Risky behavior Incapacitation School day reform Adolescent motherhood Juvenile crime Chile
