Resumen de Peer Effects in Disadvantaged Primary Schools: Evidence from a Randomized Experiment

Heather Antecol, Özkan Eren, I. Serkan Ozbeklik

• Using data from a well-executed randomized experiment, we find that the average classroom peer achievement adversely influences own student achievement in math and reading in primary schools in disadvantaged neighborhoods. In addition, using a unique feature of our data, we provide tentative evidence that our focus on students in primary schools in disadvantaged neighborhoods may potentially be the driving force behind the divergence in our results and the results in the existing literature. Finally, we show that these different peer dynamics in disadvantaged neighborhoods can potentially be explained by the frame of reference and the invidious comparison models.
