經理人過度自信與融資限制對公司研發支出之影響 / The Study of the Effects of CEOs Overconfidence and Financing Constraints on Corporate R&D Expenditures

楊芝榮 Unknown Date (has links)
以往於經理人過度自信對公司投資決策影響之研究中,大部分注重於經理人過度自信與資本投資之關係,僅有少數文獻探討經理人過度自信與R&D支出影響。 本研究主要為探討經理人過度自信、現金部位與融資限制之關聯,針對1993年至2013年間的1,892間美國公司進行分析,首先探討經理人過度自信是否影響R&D支出對現金部位的敏感度,在進一步將公司依融資限制分為五組進行探討,研究結果發現:(1)過度自信的經理人其R&D支出對於公司現金部位的敏感性較高,這隱含過度自信的經理人在公司擁有充裕的現金時可能會過度投資,而現金不足時可能會投資不足之情形。(2)融資限制最高的組別其R&D支出對現金的敏感度顯著大於融資限制最低的組別,同時當公司融資限制的程度提高,過度自信經理人的R&D支出對現金部位的敏感度也持續上升,這樣的結果也隱含在高度融資限制影響下,過度自信經理人在進行R&D決策時,會因公司持有的現金較多而進行更多的R&D投資。

經理人過度自信於經濟衰退時對企業併購之影響 / The impact of CEO overconfidence on mergers & acquisitions during economic recession

張暘亘, Chang, Yang Hsuan Unknown Date (has links)
本研究探討過度自信經理人於經濟衰退階段時之併購行為。本研究蒐集S&P1500大企業於1993年至2016年的資料,對過度自信經理人於景氣衰退階段的併購機率、宣告效果、長期股價表現進行分析。因為過度自信經理人低估景氣衰退所造成的高度不確定性,同時高估本身能夠透過併購所創造的公司價值,我們預期過度自信經理人相較非過度自信經理人更容易在景氣衰退的階段進行併購。然而實證結果過顯示過度自信經理人的併購機率於2008年金融海嘯後大幅下降,減少併購的幅度顯著高於非過度自信經理人。此結果和過去文獻一致,說明在財務資源不足的情況下,過度自信經理人會比非過度自信經理人更不願意投資。因為過度自信經理人高估自家公司權益價值,認為資本市場低估其權益價值,就算面對能為公司創造價值的投資案時也不願意向外發行股票籌資,因而導致他們在經氣衰退時較非過度自信經理人投資更保守。 / The study examines the behaviors of overconfident CEOs during recessions using firms included in S&P 1500 Index from 1993 to 2016. We propose that overconfident CEOs would undertake more M&As than non-overconfident CEOs during recessions for their biased beliefs lead them to underestimating the risk they would incur in recessions and overestimating the synergy they can create through M&As. However, we found that, during and after the 2008 Recessions, overconfident CEOs reduce significantly more in undertaking M&As than non-overconfident CEOs. The results are consistent with past literatures and suggest that decrease in financial resources caused by recession lead overconfident CEOs, who overestimate the value of their own equity and are unwilling to issue new equity, to reducing more in undertaking M&As than non-overconfident CEOs after and during recession.
