Top management group heterogeneity and firm performance
基于84家财富500强食品和石油公司1967-1981年的数据，检验了高层管理团队同质性与异质性在不同竞争和环境变化条件下对企业绩效的影响，发现部分支持假设，但结果也揭示了识别绩效决定因素的困难。
Using a sample of 84 Fortune 500 food and oil companies, observed over the period 1967 to 1981, this paper tests a number of hypotheses relating top management group composition to firm performance. Specifically, it was expected that homogeneous top management groups would interact more efficiently and therefore be preferable when competition is intense, but that heterogeneous groups would facilitate adaptation and therefore be preferable under conditions of environmental change. Partial support for these hypotheses was found; however, the pattern of results also highlights the numerous difficulties in untangling and identifying the determinants of firm performance.
