Predicted was that low-power negotiators initiated more optional topics compared to high-power negotiators and that this would lead to a higher negotiation quality and a higher joint outcome. Furthermore, predicted was that high-power negotiators would only initiate the optional topics that were beneficial for them, and that low-power negotiators would initiate all the optional topics. The participants (N=88 dyads) were introduced to a newly developed dyad face-to-face negotiation task, where participants had the option to initiate optional topics beside the mandatory topics, with the goal to expand the pie and reach an optimal outcome. Results show that, against expectations, high-power and low-power negotiators do not differ in the frequency they initiate the optional topics, and power does not have an effect on negotiation quality and joint outcome. Furthermore, not only high-power negotiators initiate optional topics that are beneficial for them, but low-power negotiators do this as well. Suggested is that negotiators are influenced by the way the task is framed and develop an individualistic motivation which stands in the way of creating an integrative and optimal agreement. The effects of unequal power, implications and limitations of the study and future research are further discussed.Show less
