Impact of CEO narcissism and hubris on corporate sustainability and firm performance

To explore the personality traits and corporate strategy of chief executive officers (CEOs), this study investigates how narcissistic and hubristic tendencies in CEOs affect the relationship between corporate sustainability practices (CSP) and firm performance. The primary purpose is to examine whether CEO narcissism and hubris can moderate the effect of corporate sustainability on firm performance. We investigate the influence of corporate sustainability on firm performance in three dimensions: economic, environmental, and social. The relationship between the mechanisms of supervision and agency theory is explored to assist investors in decision making. The results of this study show that compared to narcissistic CEOs, hubristic CEOs will further enhance the positive influence of CSP on corporate performance, especially in the environmental and social dimensions. This research strengthens the literature on CEO narcissism and hubris by demonstrating that CEO personality traits influence the relationship between corporate sustainability practices and firm performance.
