Standard type spaces induce belief structures defined by precise beliefs. This paper proposes and analyzes simple … construct ambiguous type spaces whose induced (ambiguous) belief hierarchies approximate the standard, precise, belief …

the second kind. It is well established that these two notions of consistency are equivalent for finite type spaces but … countable type spaces, defining in this way three levels of consistency of type spaces: weak consistency, consistency, and … strong consistency. These three levels coincide in the finite case. We fully analyze the level of consistency of type spaces …

(“beliefs determine preferences”) is negligible. In contrast, we show that, in models with finite-dimensional abstract type … spaces, the set of belief functions with this property is topologically generic in the set of all belief functions. Our …

We study type spaces where a player's type at a state is a conditional probability on the space. We axiomatize these … analysis of extensive form games. Type spaces are closely related to the sphere models of counterfactual conditionals and to …
