Abstract
This study empirically investigates the effects of public leadership (PL) on job performance (JP) and notes the mediating role of public service motivation (PSM) and the moderating role of environmental complexity (ENC) between PSM and JP. The research framework was tested using a survey of 211 civil servants working in Pakistan. The findings indicate significant positive effects of PL on JP. This relationship was partially mediated by PSM. Additionally, this study found that ENC negatively moderates the positive relationship of PSM and JP and dampens the effect of PSM on JP. The managerial implication of this study is to translate PSM into improved JP by reducing environmental complexities. Suggestions for future research are also presented.
