We investigated the effects of the timing of early prenatal care on infant health by exploiting a reform that required expectant mothers to initiate prenatal care during the first ten weeks of gestation to obtain a one-time monetary transfer paid after childbirth. Applying a difference-in-differences design to individual-level data on the population of births and fetal deaths, we identified small but statistically significant positive effects of the policy on neonatal health. We further provide suggestive evidence that improved maternal health-related knowledge and behaviors during pregnancy are plausible channels through which the reform might have affected fetal health.
