Access, Sorting, and Achievement: The Short-Run Effects of Free Primary Education in Kenya
研究了肯尼亚免费初等教育项目对学生参与、分流和小学毕业考试成绩的影响，发现该项目增加了小学完成人数、促进了私立学校进入并提高了弱势群体入学机会，且未显著降低原本在校学生的成绩。
We examine the impact of the Kenyan Free Primary Education program on student participation, sorting, and achievement on the primary school exit examination. Exploiting variation in pre-program dropout rates between districts, we find that the program increased the number of students who completed primary school, spurred private school entry, and increased access for students from disadvantaged backgrounds. We argue that the program was welfare enhancing as it promoted educational access without substantially reducing the test scores of students who would have been in school in the absence of the program.
