Research on diversity programs provides inconclusive knowledge regarding their effect on firm performance. In this study, we build on the Ability-Motivation-Opportunity framework to examine the relationship between firm diversity-enhancement program bundle and firm performance. Based on a dataset covering 2,794 U.S. publicly listed firms over 15 years, we find support for our hypothesis that firm diversity-enhancement program bundle results in a greater pay-off when it is coupled with a stronger employee ownership program at the firm level or a greater technological opportunity at the industry level. Furthermore, the pay-off is greatest when a firm’s diversity-enhancement program bundle, its employee ownership program, and its environmental technological opportunity are all high. Overall, our study provides nuanced theoretical and empirical accounts regarding a firm’s integrated diversity-enhancement efforts. It also provides novel managerial implications regarding when firms can reap the most benefit from their integrated diversity-enhancement efforts.
