Replicator Dynamics of Symmetric Ultimatum Game


We construct a symmetric version of the ultimatum mini game and analyze the stability of its equilibria in the replicator dynamics. We show that the mere symmetry does not lead to a unique social norm consistent with the observed experimental results. Moreover, the average offer in the population has to be lower than 50 % in order to have one of the equilibria consistent with the experimental data.
