Abstract: | Using stochastic frontier production functions methodology with data from 1579 private‐sector establishments, we demonstrate that HR practices are significantly associated with differences in relative firm‐level efficiency. Supplemental analysis implies that this efficiency analysis is substantively different than the common approach to evaluating HRM’s relationships with firm‐level labor productivity. The results suggest that HR practices’ contributions to relative firm‐level efficiency are an important but heretofore overlooked factor in the relationship between HRM and firm performance. |
