Abstract: We leverage the introduction of Vietnam’s primary compulsory schooling law as a natural experiment to provide new evidence on the effects of parents’ education on child mortality. Employing data from the 2009 Vietnam Population and Housing Census and a regression discontinuity design, we show that the reform increased average schooling duration by approximately half a year. Our key findings reveal that one additional year of maternal schooling induced by the law reduced child mortality by 29.4%, with the majority of improvements concentrated among women residing in rural areas, minor ethnicities, and female children. While increased paternal education also exhibited a negative impact on child mortality, the effect diminished in magnitude and became statistically insignificant when controlling for maternal education. This suggests that neglecting to account for spousal education does not introduce substantial biases in estimates of maternal education’s effect on child mortality but may lead to an upward bias in estimates for fathers’ education. Further, our results indicate that increased maternal education was associated with increasing age at marriage and first birth, reducing total fertility, and engaging more in paid work, all of which could serve as potential pathways for child mortality reduction.
