Bayes Correlated Equilibrium and the Comparison of Information Structures in Games * September 16 , 2013 Revised October

چکیده
The set of outcomes that can arise in Bayes Nash equilibria of an incomplete information game where players may have access to additional signals beyond the given information structure is equivalent to the set of a version of incomplete information correlated equilibrium which we dub Bayes correlated equilibrium. A game of incomplete information can be decomposed into a basic game, given by actions sets and payoff functions, and an information structure. We identify a partial order on many player information structures (individual suffi ciency) under which more information shrinks the set of Bayes correlated equilibria.

Bayes correlated equilibrium and the comparison of information structures in games
A game of incomplete information can be decomposed into a basic game and an information structure. The basic game defines the set of actions, the set of payoff states, the payoff functions, and the common prior over the payoff states. The information structure refers to the signals that the players receive in the game. We characterize the set of outcomes that can arise in Bayes Nash equilibrium...
متن کاملA review on symmetric games: theory, comparison and applications
Game theory models decision makers' behaviors in strategic situations. Since the structures of games are different, behavior and preferences of the players are different in various types of game. This paper reviews various situations of games. Here, characteristics of some common games are discussed and compared. Specifically, we focus on a group of games called symmetric games including Prison...
متن کاملGarbling of signals and outcome equivalence
In a game with incomplete information players receive stochastic signals about the state of nature. The distribution of the signals given the state of nature is determined by the information structure. Different information structures may induce different equilibria. Two information structures are equivalent from the perspective of a modeler, if they induce the same equilibrium outcomes. We cha...
متن کاملSeasonal variation in seminal characteristics, testicular measurements and plasma testosterone concentration in Iranian Khalkhali bucks
The aim of the present study was to determine seasonal variations in semen characteristics, testicular size, and plasma testosterone concentration in Iranian Khalkhali goats. An artificial vagina was used to collect semen from 10 bucks (2–4 years of age), from November 2013 to October 2014. Testicular circumference was higher (P<0.05) from September to October. Ejaculate volume, sperm ...
متن کاملLevel-k Auctions: Can a Non-Equilibrium Model of Strategic Thinking Explain the Winner's Curse and Overbidding in Private-Value Auctions?
This paper proposes a structural non-equilibrium model of initial responses to incompleteinformation games based on "level-k" thinking, which describes behavior in many experiments with complete-information games. We derive the model's implications in firstand second-price auctions with general information structures, compare them to equilibrium and Eyster and Rabin's (2005) "cursed equilibrium...
