New Technology in Schools: Is There a Payoff?
利用英国不同学区ICT资助规则的变化，通过工具变量法估计ICT支出对学生成绩的因果影响，发现对小学英语和科学成绩有正面作用，但对数学无显著影响。
Despite its high relevance to current policy debates, estimating the causal effect of Information and Communication Technology (ICT) investment on educational standards remains fraught with difficulties. We exploit a change in the rules governing ICT funding across different school districts of England to devise an Instrumental Variable strategy to identify the causal impact of ICT expenditure on pupil outcomes. The approach identifies the effect of being a 'winner' or a 'loser' in the new system of ICT funding allocation to schools. Our findings suggest a positive impact on primary school performance in English and Science, though not for Mathematics. Copyright 2007 The Author(s). Journal compilation Royal Economic Society 2007.
