Role of star–nonstar exchange, psychological empowerment and task complexity in shaping nonstar performance

Purpose This study aims to examine how star–nonstar exchange (SNE) influences nonstars’ performance using social information processing theory. Design/methodology/approach A time-lagged survey approach is utilized to collect data from 531 nonstars in China. Structural equation modeling and process macro models are applied to test the moderated mediation model of this study. Findings Results reveal that SNE has a positive effect on nonstars’ performance through their psychological empowerment, with task complexity moderating the relationship between psychological empowerment and innovative performance. However, no moderating effect was found for routine performance. Originality/value Although previous research has delved into how leader–member exchange and team–member exchange influence employee performance. This study uniquely concentrates on how the exchange relationship between star performers and nonstars influences nonstars’ performance – a dimension that has generally been overlooked in existing literature. Findings are important for understanding SNE influence on nonstars’ performance while managing task complexity.
