Dynamic unawareness and rationalizable behavior

Research output: Contribution to journalArticlepeer-review


We define generalized extensive-form games which allow for asymmetric awareness of actions. We extend Pearce's (1984) notion of extensive-form (correlated) rationalizability to this setting, explore its properties, and prove existence.
