The Effects of Training on Own and Co‐worker Productivity: Evidence from a Field Experiment
通过随机分配工人参加培训的实地实验，发现培训使工人绩效提升10%，且同事中受训比例每增加10个百分点，工人绩效提升0.51%。
This article identifies the effects of work-related training on worker productivity by exploiting a field experiment that randomly assigns workers to treatment and control groups combined with data on worker performance before and after training. We find that participation in the training programme leads to a 10% increase in performance. Moreover, we provide experimental evidence for externalities from training: An increase of 10 percentage points in the share of treated peers improves a worker's performance by 0.51%. Furthermore, we find that the performance increase is not due to lower quality provided by the worker.
