Excess payoff dynamics in games

We present the family of Excess Payoff Dynamics for normal-form games, where growth a strategy depends only on its current proportion and excess payoff, i.e., payoff advantage over average population payoff. Requiring dependence own natural sign-preserving condition, class essentially reduces to aggregate monotonic dynamics, functional generalization Replicator Dynamics. However, also include different subclass which contains Dynamics, Brown-von Neumann-Nash other interesting examples as, e.g., satisficing dynamics. clarify relation demand dynamics from microeconomics.
