Characterization of equilibrium existence and purification in general Bayesian games
Wei He, Xiang Sun, Yeneng Sun +1
This paper studies Bayesian games with general action spaces, correlated types and interdependent payoffs. We introduce the condition of ``decomposable coarser payoff-relevant info…
Conditional Expectation of Banach Valued Correspondences
Wei He, Yeneng Sun
We present some regularity properties (convexity, weak/weak* compactness and preservation of weak/weak* upper hemicontinuity) for Bochner/Gelfand conditional expectation of Banach…
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…
Dynamic Games with Almost Perfect Information
Wei He, Yeneng Sun
This paper aims to solve two fundamental problems on finite or infinite horizon dynamic games with perfect or almost perfect information. Under some mild conditions, we prove (1) t…
Conditional Exact Law of Large Numbers and Asymmetric Information Economies with Aggregate Uncertainty
Lei Qiao, Yeneng Sun, Zhixiang Zhang
A stochastic model with a continuum of economic agents often involves shocks at both macro and micro levels. This can be formalized by a continuum of random variables that are cond…
