CEO的會計財務背景與過度自信傾向

CEOs’Accounting or Financial Background and Overconfidence

本研究探討企業 CEO 的會計財務相關背景，是否與其過度自信的傾向有關。根據 1960 年到 2018 年 119,923 個觀測值，本研究發現具有會計財務背景的 CEO，相較於其他 CEO，在融資投資決策方面，過度自信傾向較輕；若在這些會計財務背景中聚焦在會計背景，會發現具有會計背景的 CEO，相較於其他 CEO，過度自信的傾向又較輕。此外，以上具財務會計背景或單具會計背景之 CEO，若兼具有 MBA背景，其過度自信傾向均會有所提升。

This study investigates whether the accounting or financial background of chief executive officers (CEOs) influences overconfidence. Based on a total of 119,923 observations from 1960 to 2018, my study shows that overconfidence in investing or financing activities is less predominant in CEOs with accounting or financial background. In fact, CEOs with accounting background exhibit lower levels of overconfidence than other CEOs. However, if CEOs with accounting or financial background have an MBA degree, their overconfidence increases.
