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 …

The goal of this paper is to construct a user-friendly model of unawareness. We start from an axiom system (in first … characterization theorem which describes a class of structures, called object-based unawareness structures, that correspond to this … axiom system. As an application, we explain how an object-based unawareness structure can be use to model those American …

In this paper we compare two different approaches to modeling unawareness: the object-based approach of Board and Chung …
