Interim correlated rationalizability
Eddie Dekel, Drew Fudenberg, Stephen Morris
This paper proposes the solution concept of interim correlated rationalizability, and shows that all types that have the same hierarchies of beliefs have the same set of interim-correlated-rationalizable outcomes. This solution concept characterizes common certainty of rationality in the universal type space.
