本研究以1998年至2018年美國標準普爾1500的公司作為樣本測試經理人盡責性、外向性及神經質對成本僵固性之影響，實證結果發現盡責性及外向性越高的經理人越容易於銷售衰退時延遲裁撤閒置成本，導致越高的成本僵固性；神經質越高的經理人越容易於銷售衰退時急於裁撤閒置成本，導致越低的成本僵固性。另外，本研究也額外測試了經理人在不同權力及地位之下是否對本研究的結果有所影響，研究結果發現當經理人握有較大權力或在公司地位較高時，他將有更多的能力及資源來執行自己所偏好的決策，此時經理人的特質影響成本僵固性的效果將會更為明顯。

This study is to investigate whether and how CEOs' personality traits influence cost stickiness. The empirical results show that CEOs with higher conscientiousness and extroversion are more likely to delay cutting idle costs when sales decline, resulting in higher cost stickiness; CEOs with higher neuroticism are more likely to rush to cut idle costs when sales decline, resulting in lower cost stickiness. In addition, this study additionally tests whether CEOs' different power and status had any influence on the results of this study. The results of the study finds that when a CEO holds more power or has a higher status in the company, he/she is have more ability and resources to carry out their preferred decisions, thus the effect of CEOs' personality traits on cost stickiness will be more pronounced.
