We show that for many classes of symmetric two-player games, the simple decision rule 'imitate-if-better' can hardly be … game or a quasiconcave game. Our results apply to many interesting examples of symmetric games including 2 x 2 games …, Cournot duopoly, price competition, public goods games, common pool resource games, and minimum effort coordination games. …

Both games are versions of Rock-Paper-Scissors with the addition of a …We report experiments designed to test between Nash equilibria that are stable and unstable under learning. The 'TASP …

Applying unawareness belief structures introduced in Heifetz, Meier, and Schipper (2012), we develop Bayesian games … higher awareness levels and restricted from higher to lower awareness levels. We apply Bayesian games with unawareness to … relationship between standard Bayesian games and Bayesian games with unawareness. …
