Solar lanterns are promoted across rural Sub-Saharan Africa to improve both lighting in homes and educational outcomes. We undertake a randomized controlled trial in Zimba District, Zambia, to evaluate whether solar lanterns help children study more effectively and improve academic performance. Our research design accounts for potential income effects arising from the giveaways of lanterns and also “blinds” participants to the study’s purpose.
