My research examines the responsiveness of households to policy interventions that target schools (supply side) and parents (demand side). How do Brazilian households make decisions about schooling investments for young people? Do households truly evaluate the school environment (supply side), or are these decisions primarily motivated by their ability to "afford" schooling (demand side)? The principal hypothesis is that all else equal, households respond to better quality schools by investing in more education for their children. The answers to these questions have important implications for education and social policy in Latin America, as they will provide guidance about the kinds of interventions that are most likely to result in higher levels of attendance and achievement. These results could also help policymakers and scholars to better understand the role of the household in the education process.
