Parental choice, neighbourhood segregation or cream skimming? An analysis of school segregation after a generalized choice reform
研究瑞典1992年普遍教育券改革后学校隔离的变化，发现择校机会多的地区，移民与本地学生、高学历与低学历家长子女间的学校隔离增加更多，但择校导致的隔离增幅较小。
This paper studies the evolution of school segregation in Sweden in the aftermath of the 1992 universal voucher reform, which spurred the establishment of new independent schools and introduced parental choice. We assess the relative importance of neighbourhood segregation, parental choice and the location of independent schools for school segregation. In particular, we exploit variation in school choice opportunities across municipalities and provide descriptive evidence that in regions where school choice has become more prevalent, school segregation between immigrants and natives, and between children of high/low educated parents, has increased more than in regions where choice is limited. This result also holds when we account for residential segregation and focus on excess segregation over and above the segregation that would occur if all pupils attended their assigned schools. We find that the increase in school segregation 15 years after the reform that can be attributed to choice is relatively small.
