The Impact of Training on Productivity and Wages: Firm-Level Evidence
利用企业面板数据估计在职培训对生产率和工资的影响，发现培训工人的生产率溢价远高于工资溢价，支持劳动力市场不完全竞争的理论。
This paper uses firm-level panel data of on-the-job training to estimate its impact on productivity and wages. To this end, we apply and extend the control function approach for estimating production functions, which allows us to correct for the endogeneity of input factors and training. We find that the productivity premium of a trained worker is substantially higher compared to the wage premium. Our results are consistent with recent theories that explain work-related training by imperfect competition in the labor market. © 2015 The President and Fellows of Harvard College and the Massachusetts Institute of Technology
