Peer effects have figured prominently in debates on school vouchers, desegregation, ability tracking and anti-poverty programs. Compelling evidence of their existence remains scarce for plaguing endogeneity issues such as selection bias and the reflection problem. This paper is among the first...

This paper examines the effect on earnings of graduating from five different college groups. The study is based on an administrative data set unusually rich in terms of school grades, parental characteristics and other attributes.
