Living in an electrified household has the potential to improve the opportunity set of children and youth by inducing time-use changes. Yet, the linkages between electrification and children's time-use have received little attention in the literature. We attempt to fill in this gap by offering empirical evidence from urban and rural Tanzania. Using a sample of 14,622 children aged 5 to 18 years old, we explore their educational outcomes and weekly time-use patterns for 4 types of activities, namely study time, time spent on household chores (including firewood collection), leisure time, and time spent working. We use the propensity score matching techniques as well as an instrumental variable approach to estimate the impact of household electrification on children's outcomes. Our analysis compares boys and girls as well as rural and urban locations.
