We use extreme bounds analysis (EBA) to examine the comparative growth effects of gender disaggregated and level-specific enrolment ratios in a panel of Asian economies. To test our hypotheses, we employ both endogenous and exogenous growth frameworks. The externality effects of education are positive and robust for both males and females and are relatively large and significant at primary, secondary and tertiary levels. The results are suggestive of a gender productivity gap. Asian economies can grow faster by investing more in female education.
