Abstract: In many natural environments, carefully chosen peers influence individual behavior. Using a framed field experiment at secondary schools, we examine how self-selected peers affect performance in contrast to randomly assigned ones. We find that self-selection improves performance by approximately 15% of a standard deviation relative to randomly assigned peers. Our results document peer effects in multiple characteristics and show that self-selection changes these characteristics. However, a decomposition reveals that variations in the peer composition contribute only little to the estimated average treatment effects. Rather, we find that self-selection has a direct effect on performance.
