Fertility and female labor supply in Latin America: New causal evidence

We study the effect of fertility on maternal labor supply in Argentina and Mexico exploiting a source of exogenous variability in family size first introduced by Angrist and Evans [Angrist, J., Evans, W., 1998. Children and their parents' labor supply: evidence from exogenous variation in family size. American Economic Review 88 (3), 450–577] for the United States. We find that the estimates for the US can be generalized both qualitatively and quantitatively to the populations of two developing countries where, compared to the US, fertility is known to be higher, female education levels are much lower and there are fewer formal facilities for childcare.
