Revisiting the state-space model of unawareness

Finance Research Letters, 2025, vol. 72, issue C

Abstract: We propose a knowledge operator based on the agent’s possibility correspondence which preserves her non-trivial unawareness within the standard state-space model. Our approach may provide a solution to the classical impossibility result that ‘an unaware agent must be aware of everything’.
