November 2018Do Children Benefit from Internet Access? Experimental Evidence from Peru
with Ofer Malamud, Santiago Cueto, Diether W. Beuermann: w25312
This paper provides experimental evidence for the impact of home internet access on a broad range of child outcomes in Peru. We compare children who were randomly chosen to receive laptops with high-speed internet access to (i) those who did not receive laptops and (ii) those who only received laptops without internet. We find that providing free internet access led to improved computer and internet proficiency relative to those without laptops and improved internet proficiency compared to those with laptops only. However, there were no significant effects of internet access on math and reading achievement, cognitive skills, self-esteem, teacher perceptions, or school grades when compared to either group. We explore reasons for the absence of impacts on these key outcomes with survey quest...

February 2013Home Computers and Child Outcomes: Short-Term Impacts from a Randomized Experiment in Peru
with Diether W. Beuermann, Yyannu Cruz-Aguayo, Santiago Cueto, Ofer Malamud: w18818
This paper presents results from a randomized control trial in which approximately 1,000 OLPC XO laptops were provided for home use to children attending primary schools in Lima, Peru. The intervention increased access and use of home computers, with some substitution away from computer use outside the home. Beneficiaries were more likely to complete domestic chores but less likely to read books. Treatment children scored almost one standard deviation higher in a test of XO proficiency, though there were no effects on objective and self-reported skills for using a Windows-based PC and Internet. There were positive impacts on the Raven's Progressive Matrices test among children who did not have a home computer before the intervention, but no significant effects for the sample as a whole.
