During recent years, there has been a growing interest in CEO’s narcissism across a range of disciplines. Various scholars strongly believe that CEO’s narcissism is a compelling element that should not be overlooked when analyzing various organizational outcomes and strategies. Research on CEO’s narcissism has mainly focused on its negative implications on organization outcomes. However, much less attention has been given to its effect on corporate social responsibility (CSR). This study explores the relationship between CEO’s narcissism and stakeholder-driven CSR/social issue participation (SIP). while taking into account the moderating role of outside board of directors. Using a sample of publicly traded U.S restaurants, the results support that outside board of directors play a moderating role on the relationship between CEO’s narcissism and 1) stakeholder driven CSR and 2) social issue participation (SIP).
