To identify thecausal eff ects from training, we combine a field experiment that randomly assigns workers to treatmentand control groups with panel data on individual worker performance before and after training.We fi nd that participation in the training programme leads to a 10 percent increase inperformance. Moreover, we provide experimental evidence for externalities from treated workers ontheir untreated teammates: An increase of 10 percentage points in the share of treated peers leadsto a performance increase of 0.51 percent. We provide evidence that the estimated eff ects arecausal and not the result of employee selection into and out of training. Furthermore, we fi ndthat the performance increase is not due to lower quality provided by the worker.
