The value of information is examined in a single-agent environment with unawareness. Although the agent has a correct … prior about events he is aware of and has a clear understanding of his available actions and payoffs, his unawareness may … negative, contrasting what is true in the standard model with partitional information and no unawareness. We show that the …

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.
