Abstract

Most research on ethical leadership to date investigates the consequences of ethical leadership rather than its antecedents. Here, we aim to contribute to this field by studying leader personality as a potential antecedent of ethical leader behavior. In two multisource studies, we investigated the relationships between personality traits and ethical leader behavior. Leader personality was measured through self-ratings using the five-factor personality framework. Two subordinates rated their leaders' ethical behavior. Study 1 used a unidimensional Ethical Leadership Scale (ELS). In study 2 we used this scale as well as an instrument distinguishing three different ethical leader behaviors, namely, fairness, role clarification, and power sharing. Further, in study 2 we controlled for the influence of the relationship between leader and followers (LMX). As expected, conscientiousness and agreeableness were most consistently related to ethical leadership. In study 1, after controlling for the other personality traits, conscientiousness related positively with ethical leadership. In study 2, after controlling for other traits and LMX, conscientiousness related positively with ethical leadership and the behavior role clarification, and agreeableness with power sharing and fairness. Also, emotional stability related positively with ethical leadership and role clarification after controlling for LMX. As expected, openness to experience and extraversion were unrelated to ethical leader behaviors
