How Competition Shapes Peer Effects: Evidence from a University in China (Siyu Chen and Zihan Hu)

◇ 摘要：

Competition is widely used to motivate efforts and increase performance. However, in many domains, performance is aided by cooperation between agents in addition to their own efforts. In this case, competition may impose costs on cooperation since the chance of winning is decreasing in the success of peers. Education is a natural setting where peer interactions and help from others enhance individual performance. This paper uses administrative data from a university in China to examine how competition changes peer effects and peer interactions. Exploiting randomly assigned roommates, we find that high-ability students have detrimental effects on their high-ability roommates' academic performance. More importantly, this negative peer effect increases significantly along multiple competition intensity dimensions within a dorm room. The follow-up survey we conduct reveals that this is likely driven by competition discouraging help and interactions among roommates.
