A Cross-Level Theoretical and Empirical Model of Positive Emotions, Leader Identification, and Leader–Member Exchange

Abstract. Although leader–member exchange (LMX) has been widely studied, knowledge about how followers influence the LMX process remains unknown. By integrating the broaden-and-build theory (BBT) with the emotion as social information (EASI) theory, we develop a follower-centric multilevel model to investigate how followers' positive emotions have an impact on LMX via the mediating role of leader identification and the moderating role of leaders' positive emotions. We conducted a survey with 319 Chinese employees from 67 teams. The results indicated that leader identification served as a mediating factor in the relationship between followers' positive emotions and LMX. The work unit leaders' positive emotions strengthened the relationship between leader identification and LMX and moderated the mediated relationship among followers' positive emotions, leader identification, and LMX. Altogether, our findings inform new knowledge in terms of how followers may influence the development of LMX. We also help to extend the BBT and the EASI theory to the leadership context.
