Unawareness, beliefs and games
Heifetz, Aviad; Meier, Martin; Schipper, Burkhard - 2007
We define a generalized state-space model with interactive unawareness and probabilistic beliefs. Such models are desirable for many potential applications of asymmetric unawareness. We develop Bayesian games with unawareness, define equilibrium, and prove existence. We show how equilibria are...

The coordination value of monetary exchange : experimental evidence
Camera, Gabriele; Casari, Marco - 2011
Under what conditions can cooperation be sustained in a network of strangers? Here we study the role of institutions and uncover a new behavioral foundation for the use of monetary systems. In an experiment, anonymous subjects could cooperate or defect in bilateral random encounters. This...

Dynamic unawareness and rationalizable behavior
Heifetz, Aviad; Meier, Martin; Schipper, Burkhard - 2009
We define generalized extensive-form games which allow for mutual unawareness of actions. We extend Pearce's (1984) notion of extensive-form (correlated) rationalizability to this setting, explore its properties and prove existence. We define also a new variant of this solution concept, prudent...

Beliefs, payoffs, information : on the robustness of the BDP property in models with endogenous beliefs
Gizatulina, Alia; Hellwig, Martin - 2012 - First version: December 1, 2008, This version: March 23, 2012
Neeman (2004) and Heifetz and Neeman (2006) have shown that, in auctions with incomplete information about payoffs … parameters. They argue that the set of incomplete-information models satisfying this so-called BDP property ("beliefs determine … rich and beliefs are derived by conditioning on the available information; for any agent, this information includes his own …

Bayesian games with unawareness and unawareness perfection
Meier, Martin; Schipper, Burkhard - 2013
Applying unawareness belief structures introduced in Heifetz, Meier, and Schipper (2013a), we develop Bayesian games with unawareness, define equilibrium, and prove existence. We show how equilibria are extended naturally from lower to higher awareness levels and restricted from higher to lower...

Policy Gradient Methods Find the Nash Equilibrium in N-player General-sum Linear-quadratic Games
Hambly, Ben M.; Xu, Renyuan; Yang, Huining - 2021
We consider a general-sum N-player linear-quadratic game with stochastic dynamics over a finite horizon and prove the global convergence of the natural policy gradient method to the Nash equilibrium. In order to prove convergence of the method we require a certain amount of noise in the system....
