Experience, Performance, and Earnings
研究两家美国公司中管理及专业人员的工作经验与绩效、收入的关系，发现经验与收入正相关，但与绩效评级无关或负相关，质疑在职培训人力资本模型的解释力。
This study provides direct evidence concerning the relationship between experience and performance among managerial and professional employees doing similar work in two major U. S. corporations. The facts presented indicate that while, within grade levels, there is a strong positive association between experience and relative earnings, there is either no association or a negative association between experience and relative rated performance. If we are correct that the performance ratings given to managerial and professional employees in any grade level adequately reflect those employees' relative productivity in the year of assessment, the results imply that the human capital on-the-job training model cannot explain a substantial part of the observed return to labor market experience.
