Extensive Games and Common Knowledge

نویسنده

  • Philip J. Reny
چکیده

The usual justification foc Nash equilibrium behavior involves (at least implicitly) the assumption that it is common knowledge among the playecs both that the Nash equilibrium in question will be played by all and that all playecs ace expected utility maximizers. We show that in a large class of extensive form games, the assumption that rationality is common knowledge cannot be maintained throughout the game. It is shown that this can have serious consequences on traditional extensive form solution concepts (such as Selten's (1965) notion of subgame-pecfect Nash equilibria).

Synchronic Information, Knowledge and Common Knowledge in Extensive Games

The language of extensive games is complex and rich. It allows one to express such notions as the order of moves, the information a player has when it is her turn to move, etc. It is not, however, a sufficiently rich language in the sense that there are meaningful and natural statements that one can make (about a given extensive game) whose truth cannot be decided without making the language ri...

MARTIN DUFWENBERG and JOHAN LINDI~N INCONSISTENCIES IN EXTENSIVE GAMES

In certain finite extensive games with perfect information, Cristina Bicchieri (1989) derives a logical contradiction from the assumptions that players are rational and that they have common knowledge of the theory of the game. She argues that this may account for play outside the Nash equilibrium. She also claims that no inconsistency arises if the players have the minimal beliefs necessary to...

Game theoretical solution concepts for learning agents with extensive–form games

My Ph.D thesis focuses on the study of solution concepts for rational learning agents in extensive–form games in absence of common knowledge; specifically, on the definition of solution concepts, their search, analysis of static and dynamic property, characterization of learning dynamics. Summarily, my work is finalized to better understand how to integrate more thoroughly game theory and machi...
