Every Little Bit Counts: The Impact of High-Speed Internet on the Transition to College
研究了宽带普及对高中生大学申请的影响，发现宽带接入能提升SAT成绩和申请数量，但好处主要集中在高社会经济地位学生，可能加剧了原有的不平等。
This paper examines whether high-speed Internet affects students' college applications. Our analysis links the diffusion of residential broadband to the testing and application outcomes of millions of PSAT and SAT takers and reveals that students with broadband in their postal code perform better on the SAT and apply to a higher number and more expansive set of colleges. While the availability of broadband generally improved applications to college, the effects appear to be concentrated among high-SES students, suggesting that the new technology may have increased preexisting inequities.
