Heifetz, Aviad; Meier, Martin; Schipper, Burkhard - 2007

We define a generalized state-space model with interactive unawareness and probabilistic beliefs. Such models are desirable for many potential applications of asymmetric unawareness. We develop Bayesian games with unawareness, define equilibrium, and prove existence. We show how equilibria are...

Bayesian Games with Unawareness and Unawareness Perfection

Meier, Martin; Schipper, Burkhard - 2014

Applying unawareness belief structures introduced in Heifetz, Meier, and Schipper (2012), 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...

Unawareness of Theorems

Galanis, Spyros - 2018

This paper provides a set-theoretic model of knowledge and unawareness. A new property called Awareness Leads to … Knowledge shows that unawareness of theorems not only constrains an agent's knowledge, but also, can impair his reasoning about … what other agents know. For example, in contrast to Li (2009), Heifetz et al. (2006) and the standard model of knowledge …

Unawareness, Beliefs, and Speculative Trade

Heifetz, Aviad - 2012

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

Revealed unawareness

Schipper, Burkhard - 2010 - Rev.

I develop awareness-dependent subjective expected utility by taking unawareness structures introduced in Heifetz, Meier, and Schipper (2006, 2008, 2009) as primitives in the Anscombe-Aumann approach to subjective expected utility. I observe that a decision maker is unaware of an event if and...
