Extremal Perfect Monotone Equilibria in Bayesian Games with Strategic Complementarities
Wei He, Yeneng Sun, Hanping Xu
We study sharp bounds on equilibrium behavior in Bayesian games when players may make mistakes. Under strategic complementarities, the set of behavioral perfect equilibria has a la…
Delegation without Priors
Wei He, Fei Li, Jiangtao Li +4
A principal makes decisions relying on the private information held by a biased agent. Lacking a prior over the circumstances that may arise, she seeks a delegation rule that minim…
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…
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.…
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 Expectations of Correspondences
Wei He, Yeneng Sun
We characterize the properties of convexity, compactness and preservation of upper hemicontinuity for conditional expectations of correspondences. These results are then applied to…
Stationary Markov Perfect Equilibria in Discounted Stochastic Games
Wei He, Yeneng Sun
The existence of stationary Markov perfect equilibria in stochastic games is shown under a general condition called "(decomposable) coarser transition kernels". This result covers…
On the diffuseness of incomplete information game
Wei He, Xiang Sun
We introduce the "relative diffuseness" assumption to characterize the differences between payoff-relevant and strategy-relevant diffuseness of information. Based on this assumptio…
The Necessity of Nowhere Equivalence
Wei He, Yeneng Sun
We prove some regularity properties (convexity, closedness, compactness and preservation of upper hemicontinuity) for distribution and regular conditional distribution of correspon…
