Unbeatable imitation
Duersch, Peter; Oechssler, Joerg; Schipper, Burkhard - 2012
beaten by any strategy. We provide necessary and sufficient conditions for imitation to be unbeatable in the sense that there … is no strategy that can exploit imitation as a money pump. In particular, imitation is subject to a money pump if and … condition for imitation not being subject to a money pump is that the relative payoff game is a generalized ordinal potential …

An individual evolutionary learning model meets Cournot
Arifovic, Jasmina; Diao, Liang; Hanaki, Nobuyuki - 2023
In this paper, we extend the individual evolutionary learning model by incorporating other-regarding considerations and apply the model to some Cournot games. Using the model fitted to the experimental data of a repeated 3-player Cournot game (with nonlinear cost and demand functions), we...

Stochastic Imitation in Finite Games
Josephson, Jens; Matros, Alexander - 2018
In this paper we model an evolutionary process with perpetual random shocks, where individuals sample population-specific strategy and payoff realizations and imitate the most successful behavior. For finite n-player games we prove that in the limit, as the perturbations tend to zero, only...

Once beaten, never again : imitation in two-player potential games
Duersch, Peter; Oechssler, Joerg; Schipper, Burkhard - 2012
We show that in symmetric two-player exact potential games, the simple decision rule "imitate-if-better" cannot be beaten by any strategy in a repeated game by more than the maximal payoff difference of the one-period game. Our results apply to many interesting games including examples like 2x2...
