Why Do Wages Increase with Tenure? On-the-Job Training and Life-Cycle Wage Growth Observed within Firms
发现企业内工资增长几乎只发生在在职培训期间，说明工资增长主要由同期生产率增长决定，而非合同因素。
Empirical results in this paper indicate that firm-specific wage growth occurs almost exclusively during periods of on-the-job training. This finding suggests that within-firm wage growth is mainly determined by contemporaneous productivity growth. The results provide no evidence that contractual considerations are an important source of firm-specific wage growth. Copyright 1989 by American Economic Association.
