We study the effects on performance of incentives framed as gains or losses, as well as the effort channels through which individuals increase performance. We also explore potential spill-over effects on a non-incentivised activity. Subjects participated in a medically framed real-effort task under one of the three contracts, varying the type of performance incentive received: (1) no incentive; (2) incentive framed as a gain; or (3) incentive framed as a loss. We find that performance improved similarly with incentives framed as losses or gains. However, individuals increase performance differently under the two frames: potential losses increase participants’ performance through a greater attention (fewer mistakes), while bonuses increase the time spent on the rewarded activity. There is no spill-over effect, either negative or positive, on the non-incentivised activity. We discuss the meaning and implications of our results for the design of performance contracts.

We present and test a model examining the role of organizational and psychological resources that enable employees’ high-quality service provision in public safety jobs. Through a two-study design conceptualized in the principle of reciprocity of social exchange theory, we recruited 120 firefighters and 119 police officers and found that service quality was positively associated with their trust in the administration, training, and staffing sufficiency. We also found that police officers’ prosocial motivation, as a psychological resource, amplifies the relationship between trust in administration and service quality. The beneficial role of prosocial motivation in police officers’ service quality appears to counter recent research suggesting that prosocial motivation has a dark side in demanding contexts. Our findings contribute to and highlight essential connections between distinct resources that positively impact the service quality of firefighters and police officers in dangerous and emotionally demanding job roles.

Drawing on social learning theory and taking a motivational perspective, this study mainly investigates how leader humility can promote employees' other-oriented motivations, and uncovers the other-serving motivational mechanism through which leader humility can impact their employees' different types of voice behavior. By collecting data from 152 leader–subordinate dyads through an online survey, the results revealed that leader humility was positively related to both employees' prosocial motivation and organizational concern motivation. Meanwhile, these two motivations play mediating roles in explaining how leader humility can positively affect employees' supportive voice and challenging voice. It is noteworthy that leader humility, which features highlighting the value and strength of others, is more likely to trigger employees' prosocial motivation and thus influence their voice behavior. This research extends our understanding of leader humility, employee motivation, and workplace voice. Practical implications and limitations of the results are also discussed.

The fundamental nature of humility and prosocial motivation entails transcending self-interest to enact behaviors that benefit others. We theorize that leader humility may enact a self-transcendent contagion effect that will manifest in enhanced follower prosocial motivation. Due to the fundamental nature of humility, this construct holds great promise in understanding how contextual signals (i.e., leader behaviors) shape prosocial motivation in followers. In this study, we find that leader humility impacts follower prosocial motivation through followers' perception of work meaningfulness. Specifically, we found that leader humility is positively related to prosocial motivation. We also found that this relationship is mediated by followers' perception of work meaningfulness, and that this mediation is moderated by followers' perception of relational vitality. Theoretical and practical implications are discussed.
