研究了马萨诸塞州特许学校扩张对非特许学校学生的财政和教育影响，发现扩张未改变生均收支，但促使学区将支出从资本投资转向教学和薪酬，并提高了非特许学生的数学成绩。
<h3>Abstract</h3> Do charter schools drain resources and high-achieving peers from non-charter schools? We provide new evidence on the fiscal and educational consequences of charter expansion for non-charter students in Massachusetts, which temporarily compensates districts losing students to charter schools. Exploiting a 2011 reform that lifted caps on charter schools for underperforming districts, we use complementary synthetic control (SC) and differences- in-differences instrumental variables (IV-DiD) estimators. Our results suggest charter expansion leaves districts' overall per-pupil revenue and expenditure unchanged, but induces districts to shift expenditure from capital investment and support services to instruction and salaries, and ultimately increases non-charter students' achievement in math.
