Training, Wage Growth, and Job Performance: Evidence from a Company Database

Abstract

A unique dataset collected from the personnel records of a large company is used to study the relationship between on-the-job training and worker productivity. The analysis shows how information contained in a company database is useful for eliminating heterogeneity bias in the estimation of training's impact on wages and job performance. Even when selection bias in assignment to training programs is eliminated, training is found to have a positive and significant effect on both wage growth and the change in job performance scores, thereby confirming the robustness of the relationship between training and productivity.
