Does the Increase in Competition between Schools Improve the Quality of the Service? The Role of Educational Reform in Chile
研究智利学校间地理竞争对学业成绩的影响，发现公立学校数量增加提升周边学校质量，而凭单制学校数量增加则因学生筛选导致成绩下降。
We analyse the effect of geographic competition between schools on academic performance in Chile. The analysis controls for prior pupil performance, and a range of school and municipality characteristics. We allow for the endogeneity of voucher school location, using the number of local Catholic churches as an instrument. We find that a larger number of public schools positively affects the quality of education of other schools located in the same area, particularly amongst middle-class families and in middle-ranking schools. However, the number of voucher schools is associated with lower performance in neighbouring schools, which we attribute to pupil sorting.
