Abstract
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\u27s 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
