CEO Power and Top Management Team Tenure Diversity: Implications for Firm Performance

Using agency theory, we explore how the CEO (as principal) and the top management team (TMT) members (as agents) interactively influence the performance of a firm. By adding performance feedback theory into agency relations, we investigate whether the interactive effect of CEO–TMT 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
