Analyses of multiphase and multisource data show that employees’ psychological ownership mediates the relationships between job engagement and both proactive performance and knowledge hiding behavior. The effect of job engagement on employee proactive performance via psychological ownership is stronger when employees perceive they invest more into jobs more than their supervisor and colleges. Employees’ trait motivations further moderate the indirect effect of job engagement on proactive performance and knowledge hiding behavior through psychological ownership such that approach-oriented trait motivation strengthens the positive relationship between psychological ownership and proactive performance while avoidance-orientated trait motivation amplified the positive linkage between psychological ownership and knowledge hiding behavior. Theoretical and practical implications of this study are discussed. ER -
