Leader power and leader self-serving behavior: The role of effective leadership beliefs and performance information

In this research we investigated the role played by leader power in determining leader self-serving behavior. Based on an integration of insights from research on the determinants of leader behavior and the power-approach theory, we hypothesized that with higher leader power leader self-serving behavior is determined more by internal states like effective leadership beliefs and less by external cues like performance information. We found support for this prediction across two experiments and one organizational survey assessing leader behavior along a self-serving–group-serving continuum. Overall, these results suggest that whether leaders benefit the collective or act self-servingly is not a function of their power per se but rather that leader power determines the extent to which internal belief states or external cues influence leader self- versus group-serving behavior.
