We define a generalized state-space model with interactive unawareness and probabilistic beliefs. Such models are … desirable for potential applications of asymmetric unawareness. We compare unawareness with probability zero belief. Applying … our unawareness belief structures, we show that the common prior assumption is too weak to rule out speculative trade in …

defining unawareness and knowledge in terms of preferences over acts in unawareness structures and showing their equivalence to … the epistemic notions of unawareness and knowledge, we try to build a bridge between decision theory and epistemic logic …Morris (1996, 1997) introduced preference-based definitions of knowledge of belief in standard state-space structures …

We define generalized extensive-form games which allow for mutual unawareness of actions. We extend Pearce's (1984 …

I develop awareness-dependent subjective expected utility by taking unawareness structures introduced in Heifetz, Meier … events. I discuss in what sense impersonal expected utility can not represent unawareness. …

cannot handle the notions of finite belief hierarchy and unawareness among others. In this paper we consider a generalization … spaces can and more, finite belief hierarchies and unawareness among others. We also demonstrate that the universal …

We generalize the "No-trade" theorem for finite unawareness belief structures in Heifetz, Meier, and Schipper (2009) to …

induced by EFR strategies. PR applies also to generalized extensive-form games which model mutual unawareness of actions … by Milgrom and Roberts (1986); yet, we also show that under unawareness full unraveling might fail. …
