This paper investigates knowledge hoarding, defined as an individual’s deliberate and strategic concealment of information, and perceived hoarding, defined as coworkers' beliefs that an individual is engaged in hoarding. We hypothesize that knowledge hoarding increases an individual’s job performance by enhancing bargaining power and influence, whereas perceived hoarding decreases the individual’s job performance because coworkers withdraw social support. We further suggest that knowledge hoarding and perceived hoarding are both detrimental to unit performance because they hurt work-related interactions and impair the unit’s ability to respond quickly to problems. Using a sample of 297 individuals embedded in 41 units in the U.S. Forest Service, we find that the positive effect of hoarding on individual performance is mediated by bargaining power, whereas the negative effect of perceived hoarding on individual performance is mediated by social support. In addition, individual hoarding and perceived hoarding both diminish unit performance. Collectively, our results reveal the mixed fortunes that befall individuals and their organizations as a result of knowledge hoarding and suspected hoarding activity.

Leaders frequently form stronger relationships with certain subordinates moreso than others, creating an inner circle of close friendships and an outer circle of more distant relationships. Three studies examine the effects of inner-circle membership on group dynamics and interpersonal influence in hierarchical teams. Study 1 finds that, compared to outer-circle members, inner-circle members feel safer and participate in the group discussion more, and leaders recognize them as making a greater contribution and allocate a larger bonus to them. Consequently, inner-circle members influence the groups' decisions more, and team decision quality improves when inner-circle members possess expert knowledge. Study 2 finds that leaders attended to and recalled suggestions from their inner circle more regardless of argument strength, suggesting heuristic information processing. Study 3 replicates these findings using intact teams in a large governmental agency. Implications for leadership and group decision making are discussed.
