As a trait, leader confidence has been examined in major leadership theories, such as transformational/charismatic, Pygmalion, and empowering leadership. However, how confidence affects leadership effectiveness remains an empirical question. Conceptualizing leadership confidence in two behavioral approaches—demonstrating self-confidence (DC-self) and demonstrating confidence in followers (DC-follower)—this study tests the independent effects of the two DC behaviors as well as their interactive effects with firm environment on followers' commitment. Results of Hierarchal Linear Modeling analyses suggest that both DC behaviors have significant impact on follower commitment and their effects attenuate each other. Results also reveal that DC-self interacts with firm environment to influence follower commitment. The effect of DC-self on follower commitment is stronger in a more competitive environment. Those findings and their implications for leadership research and practice are discussed.
