Estimating the impact of child health investments on adult living standards entails multiple methodological challenges, including the lack of experimental variation in health status, an inability to track individuals over time, and accurately measuring living standards and productivity in low-income settings. This study exploits a randomized school health intervention that provided deworming treatment to Kenyan children, and uses longitudinal data to estimate impacts on economic outcomes up to 20 y later. The effective respondent tracking rate was 84%. Individuals who received two to three additional years of childhood deworming experienced a 14% gain in consumption expenditures and 13% increase in hourly earnings. There are also shifts in sectors of residence and employment: treatment group individuals are 9% more likely to live in urban areas, and experience a 9% increase in nonagricultural work hours. Most effects are concentrated among males and older individuals. The observed consumption and earnings benefits, together with deworming’s low cost when distributed at scale, imply that a conservative estimate of its annualized social internal rate of return is 37%, a high return by any standard.

The impact of urban migration on ethnic politics is the subject of long-standing debate. "First-generation" modernization theories predict that urban migration should reduce ethnic identification and increase trust between groups. "Second-generation" modernization perspectives argue the opposite: Urban migration may amplify ethnic identification and reduce trust. We test these competing expectations with a three-wave panel survey following more than 8,000 Kenyans over a 15-year period, providing novel evidence on the impact of urban migration. Using individual fixed effects regressions, we show that urban migration leads to reductions in ethnic identification; ethnicity's importance to the individual diminishes after migrating. Yet urban migration also reduces trust between ethnic groups, and trust in people generally. Urban migrants become less attached to their ethnicity but more suspicious. The results advance the literature on urbanization and politics and have implications for the potential consequences of ongoing urbanization processes around the world.

While Ethiopia has seen a rapid expansion of school enrollment over the past 25 years, especially in primary education, dropout, absenteeism, and grade repetition remain key challenges to achieving the education-related Sustainable Development Goals. This article uses the 2017/18 Gender and Adolescence: Global Evidence (GAGE) survey of 6800 Ethiopian adolescents and regression analysis to examine how exposure to and /or experience of violence (from peers and at home), adolescent decision-making power in the household, and paid and unpaid child work are related to absenteeism, dropout, and on-time completion in primary school. The findings provide empirical evidence on the positive association between adolescent decision-making power in the household and educational outcomes and the negative relationships between adolescent education and both exposure to and /or experience of violence and paid and unpaid child work. We explore variations in the magnitude and robustness of these associations across gender, age cohort, and rural/urban residential location. Our findings suggest that programs which enhance decision-making power of adolescents in the household reduce exposure to and/or experience of violence among peers and at home and reduce participation in paid and unpaid child work which can improve adolescent educational attainment.

Despite its cultural and biological importance, limited knowledge about menstruation and cultural taboos in many contexts mean that menarche often brings fear and stigma. In Ethiopia, the context of this paper, lack of knowledge and the stigma around menstruation create challenges for adolescent girls related to menstrual hygiene management and their reproductive health more broadly. This paper uses a cluster-randomized controlled trial (cRCT), with 97 communities (kebeles) randomly assigned to treatment or control, to assess the impact of a gender-transformative life-skills intervention [Act With Her-Ethiopia (AWH-E)] on the menstrual health literacy of very young adolescent girls and boys (10–14) in two diverse regions of Ethiopia (South Gondar, Amhara and East Hararghe, Oromia). The evaluation employs a longitudinal mixed-methods design, with baseline data collected in late 2017/early 2018 and follow-up data collected in late 2019/early 2020. Quantitative surveys were undertaken with 2,492 very young adolescents and their primary caregivers, and complemented by qualitative interviews with 291 adolescents and their caregivers, as well as 96 key informants at community and district levels. Our quantitative findings highlight large and statistically significant improvements on norms around menstruation, knowledge about menstruation and biological function, and knowledge and behavior related to menstrual hygiene management, but with important differences by location and gender. Qualitative findings further unpack these gender and regional differences, highlighting the importance of adapting programming to the local context and, where possible, connecting to other health and gender initiatives. This analysis helps fill the evidence gap on “what works” to improve menstrual health literacy in rural low- and middle-income contexts.
