Long-run Effects of Universal Pre-Primary Education Expansion: Evidence from Argentina

We study the long-run effects of a large public expansion of pre-primary education in Argentina. Between 1993 and 1999 the federal government financed the construction of new preschool classrooms targeted to departments with low base- line enrollment and high poverty, creating roughly 186,000 additional places. We link administrative records on classroom construction to four population censuses and estimate difference-in-differences models that compare treated and untreated cohorts across high- and low-construction departments. An additional preschool seat per child increases post-kindergarten schooling by about 0.5 years, raising the probability of completing secondary school by 11.9 percentage points and of enrolling in post-secondary education by 7.1 percentage points. For women, access to the program also reduces completed fertility: an additional seat lowers the number of live births per woman by 0.18, and we find no evidence that selective migration biases these estimates. We find little impact on labor-market outcomes at the census date, consistent with beneficiaries still being in school or in the early stages of their careers. A benefit-cost analysis based on the estimated schooling gains, standard Mincer returns, and observed construction and operating costs yields a benefit-cost ratio of about 11 and an internal rate of return of 13%. Our findings show that universal at-scale pre-primary expansions in middle-income countries can generate sizable improvements in human capital and demographic outcomes at relatively low fiscal cost.
