The Effect of Charter Schools on School Segregation
研究了特许学校扩张如何影响公立学校的种族隔离，发现特许学校轻微加剧了种族隔离，但减少了学区间的隔离。
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.
