Abstract
This study investigates the effect of CEO narcissism on firm's cash conversion cycle (CCC), and how this influence is moderated by CEO gender. Based on a sample of 354 CEOs in 229 S&P 500 firms, our results indicate that firms led by more narcissistic CEOs tend to have a shorter CCC and this effect is weaker in companies led by a female CEO. Our additional analyses show that the effect of CEO narcissism on the CCC may improve or damage firm performance depending on the firm's CCC level.
