大都会教育机会理事会（Metco）是一个废除种族隔离的计划，将波士顿学校的学生送到更富裕的郊区。Metco增加了黑人的数量，降低了接收区的考试成绩。马萨诸塞州的学校层面数据和一个大区的微观数据显示，Metco对非Metco学生的白色成绩没有影响。但微观估计显示了一些对少数民族三年级学生，特别是女孩的影响的证据。三年级学生的工具变量估计是不精确的，但一般符合普通最小二乘估计。鉴于这些结果的局部性质，我们得出结论，美科的同行效应是温和的，短暂的。
The Metropolitan Council for Educational Opportunity (Metco) is a desegregation program that sends students from Boston schools to more affluent suburbs. Metco increases the number of blacks and reduces test scores in receiving districts. School-level data for Massachusetts and micro data from a large district show no impact of Metco on the scores of white non-Metco students. But the micro estimates show some evidence of an effect on minority third graders, especially girls. Instrumental variables estimates for third graders are imprecise but generally in line with ordinary least squares estimates. Given the localized nature of these results, we conclude that peer effects from Metco are modest and short lived.
