Cash transfer (CT) policy is promoted as an important financial vehicle to address household poverty and bring positive societal development. This study investigates the impact of an unconditional CT policy on children's education outcomes focusing on both the primary and secondary phases of education. We also examine the spillover effect of CT policy on parents' employment. To identify these effects we focus on South Africa and exploit the changes in age eligibility requirements of the CT policy to build credible control and treatment groups based on birth cohort. Our results show that CT policy improves reading and writing abilities at both the primary (by 3.7% and 3.3% respectively) and secondary education levels (by 10.2% and 10.1%, respectively) but it fosters school attendance only in secondary education. We also provide evidence that, for primary education students, the effects are only significant for boys. Notably, the positive effects of CT programs are also confirmed by the presence of spillover effects to other members of the family in our observance of increases in both mothers' and fathers' employment outcomes (by 35% and 34%, respectively). Therefore, in this paper we provide robust evidence that unconditional CT policy supports resilient development of the country's population in several dimensions that go beyond the educational achievement of targeted children.
