Although it is widely recognized that accounting for spillovers from higher education institutions is essential when formulating educational policy, research on these effects in developing countries is scarce. This study examines the spillover effects of Ethiopia's recent public university expansion program on the educational attainment of female adolescents in the surrounding areas. The study uses econometrics techniques that account for selection biases and causally demonstrates the positive effects of university expansion on female academic achievement. The study also documents other behavioral changes, such as changes in their fertility and reproduction decisions and information-seeking behavior.
