The presence of a separate COO/president and its impact on strategic change and CEO dismissal
研究CEO与COO/总裁分设对战略变革和CEO解聘的影响，发现低绩效时分设会加大战略变革并增加CEO解聘概率，高绩效时则减少战略变革且不影响解聘。
Abstract This study focuses on the leadership structure at the very top of a firm. Specifically, it examines how the presence of a COO/president, who is separate from the CEO, affects strategic change and CEO dismissal. With longitudinal data on the tenures of 207 CEOs, results suggest that the presence of a separate COO/president increases the magnitude of strategic change under conditions of low firm performance but it decreases the magnitude of strategic change under conditions of high firm performance. In addition, the presence of a separate COO/president increases the likelihood of CEO dismissal under conditions of low firm performance, and this effect is stronger when the magnitude of strategic change is high; but it has no impact on the likelihood of CEO dismissal under conditions of high firm performance. These results suggest that the impact of the presence of a separate COO/president on strategic change and CEO dismissal varies across different organizational contexts.
