Economists theorize that the inverse relationship between income and family size reflects a trade-off between child quality and quantity. Testing this hypothesis requires addressing the simultaneity of the quality and quantity decisions. The unanticipated birth of twins and sex composition of the first two children have been used as the exogenous variation in family size with mixed results. We exploit the One-Child Policy (OCP) in China, which exogenously reduced fertility, and examine how the OCP affected the education of Chinese migrants to the USA. Using the American Community Survey and a difference-in-differences strategy, we find higher levels of education for Chinese migrants born after the OCP compared with their counterparts from other East Asian countries. This finding provides additional support for the existence of a quality-quantity trade-off.
