    (VF)Outre la mesure de l’impact de l’annonce des suppressions d’emplois, réalisée à travers une d’étude d’événements, cette recherche intègre une série de critères qui caractérisent les suppressions d'emplois. Deux résultats majeurs sont à noter. 1) Aucun impact significatif n’est mis en évidence dans trois cas : a) si le motif exprimé est offensif, b) si la société appartient à un secteur industriel ou à celui des services des technologies de l’information, c) si les suppressions d’emplois ne concernent qu’un site particulier. 2) Un impact significatif négatif apparaît dans trois cas : a) si la source de l’information de l’annonce des suppressions d’emplois est syndicale et que le motif est réactif, b) si la société concer-née appartient à un secteur des servi-ces autre que celui des technologies de l’information, et c) si les suppressions d’emplois sont supérieures à 10 % de l’effectif total.(VA) The impact of layoff announcements on shareholder value is measured through event study methodology. Furthermore, the study includes several factors that characterize the type of downsizing. Two main results can be pointed out. 1) The absence of a significant impact in three cases : a) if the expressed motives of layoffs are offensive, b) if the company belongs to an industrial sector or to the IT sector, and c) if only one site is concerned. 2) A significant negative impact is observed in three cases : a) if the information source is labor unions and the expressed motivation is reactive, b) if the company belongs to the services sector excluding the IT sector, and c) if the overall percentage of layoffs is more than 10 %.
