We examine the effect of more precise cost information on contract renegotiations between supply-chain parties. Specifically, we experimentally investigate the benefits of activity-based costing (ABC) information to address common supply-chain inefficiencies that are caused by the buyer or the seller, but have the same underlying costs. Results suggest that the impact of more precise cost information depends crucially on the cause of the inefficiency that parties need to address during the negotiation. ABC information increases the total joint profit in the supply chain. However, ABC information increases the seller's perceptions of the fairness of the buyer's arguments for contract changes only when the buyer causes the inefficiency but not when the seller causes the inefficiency. The combined effect of ABC information on joint profit and fairness perceptions thus increases the buyer's profit only when buyer causes the inefficiency but not when the seller causes the inefficiency.

We examine how incentive systems influence knowledge transfer between group members with equal or different status who solve an interdependent task. In our experiment, group members receive group or individual incentives, while status is manipulated by assigning job titles with corresponding role descriptions. Although all conditions require knowledge sharing to maximize payoffs, our results suggest that significantly more knowledge is shared under group incentives relative to individual incentives when status differences are present, whereas the amount of knowledge shared does not differ across these incentive manipulations for equal-status groups. These findings are in line with theory suggesting that individual incentives can motivate knowledge sharing among equal-status groups, but cannot overcome the negative interactions that arise under status differences. Instead, group incentives are required to induce cooperative behavior that mitigates the negative effects of status differences on knowledge sharing. We contribute to the literature and practice by showing that the effect of incentives depends on the social context and that job titles can have unintended consequences.
