|October 2017||Parental Monitoring and Children's Internet Use: The Role of Information, Control, and Cues|
with Ofer Malamud, Cristian Pop-Eleches: w23982
This paper explores how asymmetric information between parents and children and direct parental controls can influence children’s internet use in Chile. We designed and implemented a set of randomized interventions whereby approximately 7700 parents were sent weekly SMSs messages with (i) specific information about their children’s internet use, and/or (ii) encouragement and assistance with the installation of parental control software. We separate the informational content from the cue associated with SMS messages and vary the strength of the cues by randomly assigning whether parents received messages in a predictable or unpredictable fashion. Our analysis yields three main findings. First, we find that messages providing parents with specific information reduce children’s internet use b...
|December 2016||Books or Laptops? The Cost-Effectiveness of Shifting from Printed to Digital Delivery of Educational Content|
with Rosangela Bando, Paul Gertler, Dario Romero: w22928
Information and communication technologies, such as laptops, can be used for educational purposes as they provide users with computational tools, information storage and communication opportunities, but these devices may also pose as distractors that may tamper with the learning process. This paper presents results from a randomized controlled trial in which laptops replaced traditional textbook provision in elementary schools in high poverty communities in Honduras in 2013 through the program Educatracho. We show that at the end of one school year, the substitution of laptops for textbooks did not make a significant difference in student learning. We additionally conducted a cost-effectiveness analysis, which demonstrated that given the low marginal costs of digital textbook provision, th...
|February 2014||Institutions, Human Capital and Development|
with Daron Acemoglu, James A. Robinson: w19933
In this paper we revisit the relationship between institutions, human capital and development. We argue that empirical models that treat institutions and human capital as exogenous are misspecified both because of the usual omitted variable bias problems and because of differential measurement error in these variables, and that this misspecification is at the root of the very large returns of human capital, about 4 to 5 times greater than that implied by micro (Mincerian) estimates, found in some of the previous literature. Using cross-country and cross-regional regressions, we show that when we focus on historically-determined differences in human capital and control for the effect of institutions, the impact of institutions on long-run development is robust, while the estimates of the ef...
