By adding performance feedback theory into agency relations, we investigate whether the interactive effect of CEO¨CTMT relations on firm performance differs when past firm performance is either poor or strong. Using a sample of 115 Japanese firms, our results show that the interactive effect of CEO power and TMT tenure diversity on firm performance is positive in a situation of poor past firm performance. However, in a situation of strong past firm performance, the opposite result is found. These findings imply that CEO power might play a significant role in enhancing the effectiveness of TMT diversity on firm performance when past firm performance is poor %K top management team %K tenure diversity %K CEO power %K past firm performance %U https://journals.sagepub.com/doi/full/10.1177/1548051818789371
