Buy the Book? Evidence on the Effect of Textbook Funding on School-Level Achievement
利用加州一项诉讼提供的教科书资助准实验，发现每生96.90美元的一次性资助对小学成绩有显著正面影响且效益高，但对中学无显著效果。
This paper considers the effect of textbook funding on school-level test performance by using a quasi-experimental setting in the United States. I consider a lawsuit in California that provided a one-time payment of $96.90 per student for textbooks if schools fell below a threshold of academic performance. Exploiting this variation with a regression discontinuity (RD) design, I find that textbook funding has significant positive effects on school-level achievement in elementary schools and has a high benefit-per-dollar. In contrast to elementary schools, I find no effect in middle and high schools though these estimates are very imprecise.
