The impact of managerial narcissism and managerial overconfidence on corporate reputation: the moderating role of managerial myopia

Purpose This study aims to assess the impact of managerial narcissism and overconfidence on corporate reputation moderated by managerial myopia for companies listed on the Tehran Stock Exchange (TSE). Design/methodology/approach The sample comprises 191 companies listed on the TSE from 2014 to 2023. Corporate reputation was assessed using a brand equity scale. The analysis focused on managers’ behavioral characteristics, including narcissism, overconfidence and myopia. A control-function approach was used to address potential endogeneity. Findings The results show that managerial narcissism has a positive influence on corporate reputation. However, managerial overconfidence negatively affects corporate reputations. Managerial myopia strengthens the effect of managerial narcissism/overconfidence on corporate reputation. These findings remain consistent, even after conducting various robustness tests. Originality/value The combined influence of managerial psychological traits on corporate reputation represents a complex dynamic that has received limited scholarly attention. This study advances the literature by empirically demonstrating the moderating role of managerial myopia in shaping corporate reputation, and underscores the need to investigate how personal psychological and behavioral traits affect managerial decision-making.
