School Choice and Segregation: Evidence from an Admission Reform
利用斯德哥尔摩高中招生改革数据，评估学校选择对隔离的影响，发现新政策不仅加剧了能力隔离，还显著增加了家庭背景和种族隔离。
We evaluate the effects of school choice on segregation using data from an admission reform in the Stockholm upper secondary schools. Before 2000, the students were assigned to their nearest school, but from the fall of 2000, the students can apply to any school within Stockholm and admission decisions are solely based on grades. As expected, the new admission policy increased segregation by ability. However, segregation by family background, and especially segregation between immigrants and natives, also increased significantly. The increase in segregation by family background can be explained by ability sorting, but the increase in ethnic segregation can not.
