摘要

We investigate the impacts of school-based internet access on second graders' test scores, using over 2 million student observations from a panel of Peruvian public primary schools. We identify effects up to 6+ years after installation on different cohorts of second-grade students, exploiting variation in the timing of internet access induced by the rollout of a national program. We find positive but modest short-run impacts, but importantly, these effects grow for subsequent cohorts. Indeed, short-run estimates alone would have led to differ-ent conclusions. These dynamics underscore the value of extended evaluation windows to allow benefits of educational technology to materialize. (JEL I21, I26, I28, O15)
