摘要

虽然超级明星效应已经在体育赛事中被记录下来，但在体育之外的实证测试却很少。我们估计超级明星在课堂上的影响。我们发现，在学习表现优异的班级里，大学生的成绩比在没有这种异常值的班级里的学生低1%左右。分布底部的异常值也是有害的。由于在学术分布的高端和低端都存在异常值时，高成就者的表现更差，我们认为，激励的操纵是我们估计效果背后的机制。

Why Try? The Superstar Effect in Academic Performance

Although the superstar effect has been documented in sports tournaments, there are few empirical tests outside sports. We estimate the impact of superstars in a classroom. We find that college students in a classroom with superior academic performers earn grades about 1% lower than when they are in classrooms without such outliers. Outliers at the bottom end of the distribution are also harmful. Since high achievers perform worse in the presence of outliers at both the top and low end of the academic distribution, we argue that the manipulation of incentives is the mechanism behind our estimated effect.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
