Abstract

This paper conducts a large, narrative review of interventions that might plausibly (a) increase educational attainment, (b) delay childbearing, and/or (c) delay marriage for adolescent girls in low- and middle-income countries (LMICs). Using 108 interventions from 78 studies, predominantly in LMICs, the paper summarizes the performance of 15 categories of interventions in improving these outcomes. Transfer programs emerge as broadly effective in increasing educational attainment but their effects on delaying fertility and marriage remain mixed and dependent on context. Construction of schools in underserved areas and the provision of information on returns to schooling and academic performance also increase schooling. No category of interventions is found to be categorically effective in delaying pregnancies and reducing child marriages among adolescent girls. While targeted provision of sexual and reproductive health services, including vouchers and subsidies for family planning, and increasing job opportunities for women seem promising, more research is needed to evaluate the longer-term effects of such interventions. We propose that future studies should aim to measure short-term outcomes that can form good surrogates for long-term welfare gains and should collect detailed cost information.
