Note on unawareness: Negative Introspection versus AU Introspection (and KU Introspection)

Article

Abstract

We show that under mild conditions, Negative Introspection equals both KU Introspection and AU Introspection for plausible unawareness in a standard state-space model à la Dekel et al. (Econometrica 66:159–173, 1998). If, moreover, the standard state-space model satisfies Non-Delusion and Monotonicity, then AU Introspection alone is equivalent to Negative Introspection. This study provides additional insight into Dekel et al.’s result that standard state-space models preclude sensible unawareness, in terms of how AU Introspection and KU Introspection clash with Plausibility.
