We examine the impact of the expansion of charter schools on racial segregation in public schools, defined using multiple measures of racial sorting and isolation. Our research design utilizes between-grade differences in charter expansion within school systems and an instrumental variables approach leveraging charter school openings. Charter schools modestly increase school segregation for Black, Hispanic, Asian, and White students. On average, charters have caused a 6 percent decrease in the relative likelihood of Black and Hispanic students being exposed to schoolmates of other racial or ethnic groups. For metropolitan areas, our analysis reveals countervailing forces, as charters reduce segregation between districts. (JEL I21, I24, J15)

特许学校对学校隔离的影响

我们研究了特许学校的扩张对公立学校种族隔离的影响，使用多种种族分类和隔离措施来定义。我们的研究设计利用了学校系统内特许扩展的年级间差异以及利用特许学校开放的工具变量方法。特许学校适度增加了对黑人、西班牙裔、亚裔和白人学生的学校隔离。平均而言，宪章使黑人和西班牙裔学生接触其他种族或民族同学的相对可能性降低了 6%。对于大都市地区，我们的分析揭示了相反的力量，因为宪章减少了地区之间的隔离。(JEL I21, I24, J15)
