Abstract

In this paper, we estimate the extent of ability peer effects in the classroom and explore the underlying mechanisms through which these peer effects operate. We identify as low ability students those who are enrolled at least one year behind their birth cohort ("repeaters"). We show that there are marked differences between the academic performance and behavior of repeaters and regular students. The status of repeaters is mostly determined by first grade; therefore, it is unlikely to have been affected by their classroom peers, and our estimates will not suffer from the reflection problem. Using within school variation in the proportion of these low ability students across cohorts of middle and high school students in Israel, we find that the proportion of low achieving peers has a negative effect on the performance of regular students, especially those located at the lower end of the ability distribution. An exploration of the underlying mechanisms of these peer effects shows that, relative to regular students, repeaters report that teachers are better in the individual treatment of students and in the instilment of capacity for individual study. However, a higher proportion of these low achieving students results in a deterioration of teachers' pedagogical practices, has detrimental effects on the quality of inter-student relationships and the relationships between teachers and students, and increases the level of violence and classroom disruptions.
