摘要

对信息和通信技术(ICT)采用的研究表明,在高度不平等的社会中,传播过程在获取数字技术方面产生了分层,从而维持甚至增加了以前的社会经济差距。尽管技术乌托邦主义者认为,类似“每个孩子一台笔记本电脑”(OLPC)的项目可以减少社会不平等,但研究其后果的经济学文献主要关注学生的人力资本。结果没有发现任何影响,即使对乌拉圭自己的olpc启发的Ceibal计划这样成功的项目也是如此。我们使用事件研究方法来分析差异中的差异,以确定全球计划对不同收入阶层家庭对科技产品需求的影响。我们的研究结果表明,Plan Ceibal有助于弥合国内低收入家庭在个人电脑接入方面的数字差距,并促进了对互联网服务的需求。我们认为这些结果背后有两种不同的机制。在个人电脑接入方面,虽然“塞巴尔计划”被认为是一个针对公立学校小学生的普遍计划,但贫困幼儿化和双系统教育分层使得该政策在不同收入群体中表现出不同的影响。关于家庭连接,我们认为,在研究期间,Plan Ceibal降低了消费互联网服务所需的捆绑成本,影响了那些在公立学校上学的孩子比例合理且收入足以支付每月互联网费用的家庭。

Can One Laptop per Child Reduce Digital Inequalities? ICT Diffusion Patterns under Plan Ceibal
The study of information and communications technology (ICT) adoption signals that diffusion processes within highly unequal societies produces a stratification in the access to digital technologies and thus, maintains or even increases previous socio-economic disparities. Whereas technological utopians believed that One Laptop Per Child (OLPC)-like programs could reduce societal inequalities, the economic literature studying their consequences mostly focused on student's human capital. Results found no impacts, even for successful programs such as Uruguay's own OLPC-inspired Plan Ceibal. We use an event-study approach to difference-in-differences to identify the impact of Plan Ceibal on the household demand for technological goods across income quintiles. Our results show that Plan Ceibal helped to bridge domestic digital disparities in terms of access to PC for low-income households and favored the demand for internet services. We argue that two diverse mechanisms are behind these results. Regarding PC access, whereas Plan Ceibal was conceived as a universal program targeting primary level students attending public schools, both poverty infantilization and dual-system educational stratification made the policy to exhibit heterogenous impact across different income groups. Regarding household connectivity, we argue that Plan Ceibal reduced the cost of the bundle required to consume internet services at the time of the study, impacting on those households with both reasonable shares of children attending a public school and sufficient income to afford the monthly internet charges.
