In this constructive replication, we evaluate the effect of star performers on unit performance beyond the presence of other high performers and high mean levels of unit performance to clarify and confirm stars' unique contribution to unit performance. Furthermore, we extend prior work by assessing stars' moderating effect on the unit turnover-to-unit performance relationship. With a sample drawn from Major League Baseball, we confirm that stars have a positive influence on unit performance above and beyond the effects of high levels of mean unit productivity and other high performers, but that the strength of this relationship diminishes as the number of stars increases. We also find that stars moderate the relationship between unit turnover and performance such that star performers effectively eliminate the harmful effects of turnover on unit performance. However, this moderating effect is itself eliminated when the turnover rate changes drastically.

明星业绩、单位业绩和单位营业额：建设性复制

在这个建设性的复制中，我们评估了明星表现者对单位表现的影响，而不是其他高表现者和高平均水平的单位表现，以澄清和确认明星对单位表现的独特贡献。此外，我们通过评估明星对单位营业额与单位绩效关系的调节作用来扩展先前的工作。通过从美国职业棒球大联盟中抽取的样本，我们确认明星对单位表现的积极影响超出了高水平的平均单位生产力和其他高绩效者的影响，但这种关系的强度随着明星数量的增加而减弱增加。我们还发现，明星调节了单位离职率与绩效之间的关系，从而使明星绩效者有效地消除了离职对单位绩效的有害影响。然而，当周转率急剧变化时，这种调节作用本身就被消除了。
