Why top management team characteristics matter when employing a chief operating officer: a strategic contingency perspective
研究了首席运营官（COO）的存在如何影响企业绩效，发现COO能带来信息处理优势，提升资产回报率和市账比，且这种效果取决于高层管理团队的整体特征。
Abstract Critics of the CEO/COO duo have stressed that this arrangement burdens the firm with increased costs and decreases the CEO's effectiveness. This study adopts an upper echelon perspective to argue that the presence of a COO may also create TMT‐level information‐processing benefits that can improve firm performance in certain conditions. Data from a sample of 153 firms in five industries highlight a strong positive relationship between the presence of a COO and two established measures of firm performance: return on assets and market‐to‐book ratio. The data also suggest that those relationships are contingent on the broader characteristics of the TMT. Copyright © 2009 John Wiley & Sons, Ltd.
