Do intelligent leaders differentiate exchange relationships intelligently? A functional leadership approach to leader-member exchange differentiation.

The burgeoning literature on leader-member exchange (LMX) differentiation indicates that differentiating LMX relationships within groups has both benefits and costs when it comes to group effectiveness. Although some clarity is emerging surrounding the null total effect of LMX differentiation on group performance, we still know little about how leaders themselves shape the differentiation process. In this article, we extend theory to suggest that some leaders may differentiate more effectively than others.

Motivated to "roll the dice" on trust: The relationships between employees' daily motives, risk propensity, and trust.

Models of trust have focused on the notion that an employee's trust in a coworker is based on that coworker's trustworthiness and the employee's trust propensity-a generalized tendency to believe others are trustworthy. Although these models capture the general of risk associated with trusting a particular coworker, they provide insufficient insight into why an employee might the risk associated with trust on a particular day. Bringing the concept of -the tendency to accept or avoid risk-from the decision-making literature into the trust literature, we build a model of trust that suggests employees' trusting behaviors stem from both their calculated assessment of risk (encapsulated in trustworthiness and trust propensity) and their tendency to take those risks.

What does it cost you to get there? The effects of emotional journeys on daily outcomes.

Scholarly understanding of emotions and emotion regulation rests on two incompatible truths-that positive emotions are positively beneficial and should be pursued, and that changing emotions may come at a cost. With both perspectives in mind, to really conclude that pursuing higher positive affect (PA) is a worthy journey, we must take into account the cost of that journey itself. We build from the affect shift literature and draw on self-regulation theories to argue that, although end-states characterized by more positive (and fewer negative) emotions will be beneficial, the emotional changes required to "get there" will have consequences for employee regulatory resources and subsequent behavior.

To and fro: The costs and benefits of power fluctuation throughout the day.

Power is a ubiquitous element of organizational relationships. Historically in the organizational and social sciences, power has most commonly been evaluated statically. Although this approach has been beneficial thus far, it may be inconsistent with the realities that most individuals face in organizations.

Not all fairness is created equal: A study of employee attributions of supervisor justice motives.

A large body of research demonstrates that employee perceptions of fair treatment matter. The overwhelming focus of these investigations has been on how employees react to whether or not they perceive their supervisor behaved in a fair manner. We contend, however, that employees not only question and react to whether they are treated fairly, but also to they believe their supervisor acted fairly in the first place.

Exchanging one uncertainty for another: Justice variability negates the benefits of justice.

Although the importance of organizational justice is without question, our theoretical and empirical knowledge of the justice phenomenon is focused almost exclusively on mean levels of fair treatment, ignoring whether those mean levels are achieved in a consistent or inconsistent manner. This exclusive focus on average levels of justice is not surprising given the implicit assumption in the justice literature that day-to-day variations in justice are glossed over or reinterpreted by individuals. Building upon recent research demonstrating that variability in justice can be as important as average levels of fair treatment, we leverage tenets of uncertainty management theory to provide a conceptual bridge that integrates justice variability into the group engagement model.

Ethical leadership as a substitute for justice enactment: An information-processing perspective.

Why do employees perceive that they have been treated fairly by their supervisor? Theory and research on justice generally presumes a straightforward answer to this question: Because the supervisor adhered to justice rules. We propose the answer is not so straightforward and that employee justice perceptions are not merely "justice-laden." Drawing from theory on information processing that distinguishes between automatic and systematic modes, we suggest that employee justice perceptions are also "ethics-laden.

Personality similarity in negotiations: Testing the dyadic effects of similarity in interpersonal traits and the use of emotional displays on negotiation outcomes.

We build on the small but growing literature documenting personality influences on negotiation by examining how the joint disposition of both negotiators with respect to the interpersonal traits of agreeableness and extraversion influences important negotiation processes and outcomes. Building on similarity-attraction theory, we articulate and demonstrate how being similarly high or similarly low on agreeableness and extraversion leads dyad members to express more positive emotional displays during negotiation. Moreover, because of increased positive emotional displays, we show that dyads with such compositions also tend to reach agreements faster, perceive less relationship conflict, and have more positive impressions of their negotiation partner.
