Excès de confiance des dirigeants et décisions financières:une synthèse
(VF)La recherche en finance comportementale d’entreprise s’est fortement développée ces dernières années. Cet article propose une synthèse des premières recherches consacrées à l’excès de confiance des dirigeants et son impact sur les décisions financières. La littérature disponible confirme la présence marquée du biais chez les dirigeants d’entreprises et son impact sur la politique d’investissement et de financement. De nombreuses questions restent à explorer, relatives à la mesure de l’excès de confiance et à l’appréhension des effets positifs/négatifs du biais.(VA)This paper reviews the growing research area of behavioral corporate finance, focusing on articles regarding the intensity of executives’ overconfidence and its role in financial decision making. Studies report evidence of distortions in corporate investment and financing decisions due to CEO overconfidence. Many empirical challenges are emerging, related to overconfidence measures and positive/negative effects of managerial overconfidence.
