To test the possibility that overconfidence might yield important relative benefits that offset its absolute costs, we conducted an experiment (N=298 university students) in which pairs of participants bargain over the unequal allocation of a prize that was earned via a joint effort. We manipulated confidence using a binary noisy signal to investigate the causal effect of negotiators’ beliefs about their relative contribution on the outcome of the negotiation. Our results provide evidence that high levels of confidence lead to relative benefits (how much one earns compared to one’s partner) but absolute costs (how much money one receives overall). These results suggest that overconfidence creates an inefficient equilibrium whereby overconfident negotiators benefit over their partners even as they bring about joint losses. date: 2021-03 id_scheme: DOI id_number: 10.11588/heidok.00029513 schriftenreihe_cluster_id: sr-3 schriftenreihe_order: 0700 ppn_swb: 1752410173 own_urn: urn:nbn:de:bsz:16-heidok-295132 language: eng bibsort: SOLDAALICEABSOLUTEVS202103 full_text_status: public series: Discussion Paper Series / University of Heidelberg, Department of Economics volume: 0700 place_of_pub: Heidelberg pages: 22 citation: Soldà, Alice ; Ke, Changxia ; von Hippel, William ; Page, Lionel (2021) Absolute vs. relative success: Why overconfidence is an inefficient equilibrium.
