Studies of the effects of top management team (TMT) composition on organizational outcomes have yielded mixed and confusing results. A possible breakthrough resides in the reality that TMTs vary in how they are fundamentally structured. Some are structured such that members operate independently of each other, while others are set up such that roles are highly interdependent. We examine the potential for three facets of structural interdependence—horizontal, vertical, and reward interdependence—to resolve ambiguities regarding effects of TMT heterogeneity. Based on a sample of TMTs in technology firms, we find that the three facets of structural interdependence are potent moderators of two classic predictions: the positive association between TMT heterogeneity and member departures, and between TMT heterogeneity and firm performance.

While conflicts (cognitive and affective) have been considered as important process variables to better understand the mixed findings on the relationship between top management team functional diversity and organizational innovation, such an input-process-outcome model is still incomplete without considering the environmental factors. This study was formulated to assess the importance of both competitive and institutional environments in moderating such upper echelon effects within a transition economy. The chief executive officers and chief technology officers of 122 Chinese firms were surveyed and both competitive uncertainty and institutional support were found to shape top management team decision making processes and their outcomes.

In this study, we examine the influence of senior leadership on firms' corporate social responsibility (CSR). We integrate upper echelons research that has investigated either the influence of the CEO or the top management team (TMT) on CSR. We contend that functional experience complementarity between CEOs and TMTs in formulating and implementing CSR strategy may underlie differentiated strategies in CSR. We find that when CEOs who have predominant experience in output functions are complemented by TMTs with a lower proportion of members who have experience in output functions, there is a pronounced effect on the community, product, and diversity dimensions of CSR. In turn, when output-oriented CEOs are complemented by output-oriented TMTs, we observe an effect on the employee relations dimension of CSR. Interestingly, we find no influence of CEO-TMT complementarity on the environment dimension of CSR. In general, our empirical results support the relevance of the interaction between CEOs and their TMTs in defining their firms' CSR profile.

Research summary: We develop and test a contingency theory of the influence of top management team (TMT) performance-contingent incentives on manager–shareholder interest alignment. Our results support our theory by showing that although TMTs engage in significantly higher levels of acquisition investment when their average incentive levels increase, investors' responses to those large investments are generally negative. More importantly, however, we further find that within-TMT incentive heterogeneity conditions that effect, such that investors evaluate TMTs' large acquisition investments more positively as the variance in those top managers' incentive values increases. Thus, within-TMT incentive heterogeneity appears to increase manager–shareholder interest alignment, in the context of large acquisition investments. Managerial summary: We find that as the average value of TMTs' incentives increase, relative to their total pay, they invest more in acquisitions and investors' respond negatively to the announcement of those deals. However, we further show that investors respond more positively to acquisitions announced by TMTs whose members' incentive values vary (some TMT members hold higher incentives and others hold lower). Results imply that when TMT members hold differing incentives levels, they approach investments from divergent perspectives, scrutinize those investments more heavily, and make better decisions, relative to TMTs with similar incentives. They also suggest that boards seeking tighter manager–shareholder interest alignment may benefit from introducing variance into TMT members' incentive structures, as doing so appears to create divergent preferences that can improve team decision making.

While theory and evidence show that firms' competitive actions mediate the resource-performance relationship, details of top managements' roles in shaping resource utilization choices have been underemphasized. We address this oversight by integrating top management team heterogeneity and any resulting faultline strength with the resource-action-performance model to investigate how TMT composition differentially affects the model's two linkages. Specifically, we argue that TMT heterogeneity positively affects the resource-action linkage, yet negatively affects the action-performance linkage. Moreover, when heterogeneity begets strong faultlines, all such positive effect is lost. Supportive evidence from the in-vitro medical diagnostic substance manufacturing industry allows us to discuss how our findings contribute to upper echelons theory, as well as the emerging stream on resource utilization.

This study addresses an apparent disconnect between two views of strategic action: the 'economic view,' which contends that industry structure is the primary influence on strategic action, and the 'cognitive view,' which suggests that managerial cognition drives strategic action. We argue that this disconnect has created artificial boundaries between the two perspectives and has limited our ability to develop holistic explanations of strategic action. In response, we develop an integrated model that answers two questions: 1) Does industry context affect managerial cognition? 2) Does managerial cognition mediate the relationship between industry context and strategic responses to environmental changes? To examine these questions, we study the relationship between industry velocity, the structure of top management's cognitive representation of the environment, and the speed of response to environmental events. We find that industry velocity influences the structure of cognitive representations, which in turn influence the speed of response to environmental events. These results support our contention that both industry and cognition variables are critical in developing explanations of strategic actions. These results have implications for our understanding of the development of top managers' beliefs, the relationship between beliefs and action, and the nature of the complex relationship between industry context, managerial cognition, and strategic action.

Top management structures in large U.S. firms have changed significantly since the mid-1980s. The size of the executive team-the group of managers reporting directly to the CEO-doubled during this period. This growth was driven primarily by an increase in functional managers rather than general managers, a phenomenon we term \"functional centralization.\" Using panel data on senior management positions, we show that changes in the structure of the executive team are tightly linked to changes in firm diversification and information technology investments. These relationships depend crucially on the function involved; those closer to the product (\"product\" functions, e.g., marketing and R&D) behave differently from functions further from the product (\"administrative\" functions, e.g., finance, law, and human resources). We argue that this distinction is driven by differences in the information-processing activities associated with each function and apply this insight to refine and extend existing theories of centralization. We also discuss the implications of our results for organizational forms beyond the executive team. This paper was accepted by Bruno Cassiman, business strategy.

This article advances strategic management by developing a data-driven simulation method to analyze how the characteristics of a group influence the characteristics of the group's components. We apply our method to the underrepresentation of women in the top management of S&P 1,500 firms. Although extant research suggests that the presence of women in top management could be self-reinforcing, we theorize and provide strong evidence that women face an implicit quota, whereby a firm's leadership makes an effort to have a small number of women in top management, but makes less effort to have, or even resists having, larger numbers of women. In consequence, the presence of a woman on a top management team reduces the likelihood that another woman occupies a position on that team.

Financial economics has posited a limited role for idiosyncratic noneconomic manager-specific influences, but the strategic management literature suggests such individual influences can affect corporate outcomes. We investigate whether individual managers play an economically significant role in their firms' voluntary financial disclosure choices. Tracking managers across firms over time, we find top executives exert unique and economically significant influence (manager-specific fixed effects) on their firms' voluntary disclosures, incremental to known economic determinants of disclosure, and firm- and time-specific effects. Managers' unique disclosure styles are associated with observable demographic characteristics of their personal backgrounds: managers promoted from finance, accounting, and legal career tracks, managers born before World War II, and those with military experience develop disclosure styles displaying certain conservative characteristics; and managers from finance and accounting and those with military experience favor more precise disclosure styles. These plausible associations confirm that our estimated manager-specific fixed effects capture systematic long-lived differences in managers' unique disclosure styles.

Expanding into new product areas is an important part of the growth strategy of many firms, but there is still more to learn about how it affects firm performance. We believe that as the top management team (TMT) is responsible for coordinating product expansion, looking there can yield valuable clues. We argue that diversification entails significant additional information processing and that this strains top managerial resources. We hypothesize that task-related faultlines within the TMT may help it cope with product expansion while bio-demographic faultlines may hinder it. We find support for these hypotheses on a longitudinal sample of 2,730 expansion steps made by 61 German firms between 1985 and 2007: task related faultline strength increases performance when diversifying, while bio-demographic faultline strength decreases it.
