Theoretical Economics 2, no. 1: 15-40.1933-6837http://nrs.harvard.edu/urn-3:HUL.InstRepos:3196333This 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.en-USrationalizabilityincomplete informationcommon certaintycommon knowledgeuniversal type space
