We define a cautious version of extensive-form rationalizability for generalized extensive- form games with unawareness … set. We demonstrate the applicability of prudent rationalizability. In games of disclosure of verifiable information, we … show that prudent rationalizability yields unraveling under full awareness but unraveling might fail under unawareness. We …

Heifetz, Meier and Schipper (2013) introduced generalized extensive-form games that allow for asymmetric unawareness … generalized extensive-form game with unawareness may consist of a collection of normal-form games. We use it to characterize … unawareness, a player's information set not only determines which nodes he considers possible but also of which game tree(s) he is …

We extend Kuhn's Theorem to extensive games with unawareness.
