Giacomo Bonanno. Revealed preference, iterated belief revision and dynamic games. In Information processing, rational belief change and social interaction. Dagstuhl Seminar Proceedings, Volume 9351, pp. 1-10, Schloss Dagstuhl – Leibniz-Zentrum für Informatik (2009)


In previous work (G. Bonanno, Rational choice and AGM belief revision, Artificial Intelligence, 2009) a semantics for AGM belief revision was proposed based on choice frames, borrowed from the rational choice literature. In this paper we discuss how to use choice frames to analyze extensive-form games. Given an extensive form with perfect recall, a choice frame can be used to represent a player's initial beliefs and her disposition to change those beliefs when she is informed that it is her turn to move. When some players move more than once along some play of the game, the issue of iterated belief revision arises. We provide a semantics for iterated belief revision in terms of choice frames and provide an outline of how to use choice frames to analyze solution concepts for extensive-form games.
