  1. Another forthcoming AEJ paper also finds zero impact of computers on educational outcomes in California:

    “…We test this hypothesis by conducting the largest- ever field experiment involving the random provision of free computers for home use to students. 1,123 schoolchildren grades 6-10 in 15 California schools participated in the experiment. Although the program significantly increased computer ownership and use, we find no effects on any educational outcomes, including grades, standardized test scores, credits earned, attendance and disciplinary actions. Our estimates are precise enough to rule out even modestly-sized positive or negative impacts. The estimated null effect is consistent with survey evidence showing no change in homework time or other “intermediate” inputs in education for treatment students.”
