Interactive unawareness
The standard state-spaces of asymmetric information preclude non-trivial forms of unawareness (Modica and Rustichini, 1994, Dekel, Lipman and Rustichini, 1998). We introduce a generalized state-space model that allows for non-trivial unawareness among several individuals, and which satisfies strong properties of knowledge as well as all the desiderata on unawareness proposed this far in the lit...
متن کاملInteractive unawareness revisited
We analyze a model of interactive unawareness introduced by Heifetz, Meier and Schipper (HMS). We consider two axiomatizations for their model, which capture different notions of validity. These axiomatizations allow us to compare the HMS approach to both the standard (S5) epistemic logic and two other approaches to unawareness: that of Fagin and Halpern and that of Modica and Rustichini. We sh...
متن کاملSub-models for Interactive Unawareness
We propose a notion of a sub-model for each agent at each state in the Heifetz et al (2006) model of interactive unawareness. Presuming that each agent is fully cognizant of his sub-model causes no di¢ culty and fully describes his knowledge and his beliefs about the knowledge and awareness of others. In addition by relaxing some of the conditions that Heifetz et al imposed in their framework w...
متن کاملBayesian Games with Unawareness and Unawareness Perfection∗
Applying unawareness belief structures introduced in Heifetz, Meier, and Schipper (2013a), we develop Bayesian games with unawareness, define equilibrium, and prove existence. We show how equilibria are extended naturally from lower to higher awareness levels and restricted from higher to lower awareness levels. We apply Bayesian games with unawareness to investigate the robustness of equilibri...
متن کاملProbabilistic Unawareness
The modeling of awareness and unawareness is a significant topic in the doxastic logic literature, where it is usually tackled in terms of full belief operators. The present paper aims at a treatment in terms of partial belief operators. It draws upon the modal probabilistic logic that was introduced by Aumann (1999) at the semantic level, and then axiomatized by Heifetz and Mongin (2001). The ...
