For the period 2015–2019 and based on a Spanish sample of 145 listed companies, this paper provides insights into how narcissistic chief executive officers (CEOs) influence the proportion of women in top management teams (TMTs). As a further analysis and in line with social psychology and upper echelons theories, we study whether the power and gender of a CEO and the female proportion in the firm's board moderate the relationship. Our results reveal that narcissistic CEOs are less likely to support (...) women in TMTs, confirming that CEO personality traits influence team structure. Further results suggest that this aversion increases as the CEO's power grows and is a woman, and when female proportion in board decreases. The results have an impact on the gender equality goal, demonstrating that the behavior of women toward promoting gender equality in TMTs depends both on the specific position of women in the firm's hierarchy and on their personal psychological attributes. We find that women directors support social identity values and that narcissistic female CEOs act like queen bees. (shrink)
