The current study examined the longitudinal impact of erp adoption on firm performance by matching 63 firms identified by hayes et al. [j. Inf. Syst. 15 (2001) 3] with peer firms that had not adopted erp systems. Results indicate that return on assets (roa), return on investment (roi), and asset turnover (ato) were significantly better over a 3-year period for adopters, as compared to nonadopters. Interestingly, our results are consistent with poston and grabski [int. J. Account. Inf. Syst. 2 (2001) 271] who reported no pre- to post-adoption improvement in financial performance for erp firms. Rather, significant differences arise in the current study because the financial performance of nonadopters decreased over time while it held steady for adopters. We also report a significant interaction between firm size and financial health for erp adopters with respect to roa, roi, and return on sales (ros). Specifically, we found a positive (negative) relationship between financial health and performance for small (large) firms. Study findings shed new light on the productivity paradox associated with erp systems and suggest that erp adoption helps firms gain a competitive advantage over nonadopters.
