Equity dynamics in bargaining without information exchange

  • Heinrich H. NaxEmail author
Regular Article


In this paper, completely uncoupled dynamics for n-player bargaining are proposed that mirror key behavioral elements of early bargaining and aspiration adjustment models (Zeuthen, 1930; Sauermann and Selten, 118:577–597 1962). Individual adjustment dynamics are based on directional learning adjustments, solely driven by histories of own realized payoffs. Bargaining this way, all possible splits have positive probability in the stationary distribution of the process, but players will split the pie almost equally most of the time. The expected waiting time for almost equal splits to be played is quadratic.

Much of this work is part of the author’s D.Phil. (University of Oxford, 2011; supported by the Economic and Social Research Council [grant number PTA-031-2005-00118] and Postdoc under the Office of Naval Research Grant [grant number N00014-09-1-0751]. I also acknowledge current support by the European Commission through the ERC Advanced Investigator Grant ‘Momentum’ [grant number 324247]. I am particularly thankful to Peyton Young and Steffen Issleib, with whom I worked on this topic, and to Françoise Forges, Chris Wallace and Francis Dennig for comments on earlier versions of this model. The proof technique used is due to previous, joint unpublished work. I would also like to thank anonymous referees and a helpful editor for valuable comments on earlier versions of the paper.
