Weak Atomic Continuity and Subgame Perfection
Enxian Chen, Wei He, Yeneng Sun +1
Subgame-perfect equilibrium need not exist in continuous games with perfect information when Nature moves. Under standard regularity assumptions, we prove that weak atomic continui…
Equilibrium convergence in large games
Enxian Chen, Bin Wu, Hanping Xu
This paper presents a general closed graph property for (randomized strategy) Nash equilibrium correspondence in large games. In particular, we show that for any large game with a…
Does randomization matter in dynamic games?
Enxian Chen, Wei He, Yeneng Sun +1
This paper investigates mixed strategies in dynamic games with perfect information. We present an example to show that a player may obtain higher payoff by playing mixed strategy.…
Robust perfect equilibrium in large games
Enxian Chen, Lei Qiao, Xiang Sun +1
This paper proposes a new equilibrium concept "robust perfect equilibrium" for non-cooperative games with a continuum of players, incorporating three types of perturbations. Such a…
