Management heterogeneity,competitive interaction groups,and firm performance

One of the fundamental problems in strategic management is to map a heterogeneous set of firms in an industry into subsets of firms within which firms are homogeneous in their conduct and performance. The strategic group concept provides an answer to this intriguing question. Researchers in strategic group theory argue that firms within the same strategic group are behaviorally similar and thus tend to compete more fiercely within the group than across groups. In this paper, we focus on the question whether firms within the same group show similar decision‐making characteristics. Strategic‐choice theorists argue that top management teams in firms have substantial discretion in determining the future strategic contour of firms. Upper‐echelon theorists also argue that top managers are the strategists who set the direction of firms and the pace of competition in the industry. Further, they argue that top management team characteristics are an important element that determines the market niche in which a firm competes and the strategic direction a firm follows. Based on these arguments, we expect that there will be a significant link between grouping of firms by the patterns of competitive interactions and grouping of firms by top management team heterogeneity. Moreover, we argue that the closer the TMT heterogeneity of a firm is to the dominant heterogeneity in the competitive interaction group, the better it performs.

Heavy lies the crown? How job anxiety affects top executive decision making in gain and loss contexts

Research summary: Despite abundant anecdotal evidence that many top executives experience anxiety in their jobs, the upper echelons literature has remained largely silent on the organizational implications of executive job anxiety. In this study, we theorize that job anxiety will cause executives to (1) create a social buffer against threats by surrounding themselves with supportive decision‐making teams, and (2) pursue lower‐risk firm strategies. We further argue that these effects will vary depending upon whether strategic decisions occur in gain versus loss contexts. We test our ideas using a novel multisource, multimethod approach that includes data from 84 top executives of large organizations, their decision‐making teams, their friends and families, and archival sources. Results from an analysis of 154 major strategic decisions provide general support for our theory. Managerial summary: Although many top executives experience anxiety in their jobs, some struggle more with anxiety than others. Our paper is the first to focus on how job anxiety affects executives' decisions. We analyze 154 major strategic decisions made by 84 top executives of large organizations in a range of industries, collecting data from personal interviews with executives and surveys of their decision‐making teams, spouses, and friends. We find that anxious executives take fewer strategic risks, especially when things are going well. We further argue that anxious executives focus more on “buffering” themselves from threats, and find that they surround themselves with close supporters when times are tough. Our results demonstrate a pattern through which anxiety causes top executives to focus more heavily on avoiding potential threats. Copyright © 2015 John Wiley & Sons, Ltd.     

Diversification and top management team complementarity: is performance improved by merging similar or dissimilar teams?

This study examines the impact of complementary top management teams (defined as differences in functional backgrounds between the acquiring and acquired firm managers) on post-acquisition performance. Based on a sample of 147 acquisitions completed during 1986–88, we find that complementary backgrounds have a positive impact on postacquisition performance in both related and unrelated acquisitions. Another major finding is that complementarity is negatively related to top management team turnover among acquired managers, suggesting that differences in functional backgrounds are more easily integrated into the new organization. Finally, top management team turnover among acquired managers is negatively related to postacquisition performance. These findings highlight the importance of examining complementarity in terms of differences, and reinforce the notion that differences have the potential to create unique value for the organization. © 1997 by John Wiley & Sons, Ltd.
