The personality factor: how top management teams make decisions. A literature review

Past research has increasingly suggested that CEO/TMT personality can play a relevant role in influencing various external (e.g. firm performance) and internal (e.g. firm organizational structure) management outcomes. These promising results need appropriate systematization and discussion, which we aim at providing through a literature review based on rigorous inclusion/exclusion criteria. Our analysis shows great heterogeneity in regard to both the personality traits and the personality based management outcomes explored by the investigated population of studies. Thus, we specifically use the framework provided by the Five-Factor Model (FFM) of personality to codify the publications and this framework allows us to identify some possible theoretical trajectories. These trajectories mainly regard the empirical testing of the highlighted associations between CEO emotional stability, extraversion and conscientiousness with bureaucratization, strategic pro-activity and firm performance. Our article is primarily intended for those scholars and practitioners who want to improve their knowledge about psychology-based decision making and behavioural corporate governance through the understanding of how CEO/TMT personality can affect their strategic decisions.
