The effect of colleague quality on top performance: the case of security analysts
利用九年间顶尖证券分析师的面板数据，研究发现顶尖绩效并非个人独有，同事质量显著影响其维持高水平表现的能力。
Abstract Using a unique panel dataset of top performing security analysts over a nine‐year period, we show that top performers do not “own” their performance, even in the knowledge‐intensive work performed in this professional business services context. While an individual's past performance does indicate future performance, the quality of colleagues in one's organization also significantly affects top performers' ability to maintain their performance. Specifically, top performers in professional business services rely on high‐quality colleagues both to improve the quality of their own work and to deliver it effectively to clients.
