Informational Robustness of Common Belief in Rationality

Author

  • Gabriel Ziegler

Abstract

In this note, I explore the implications of informational robustness under the assumption of common belief in rationality. That is, predictions for incomplete-information games which are valid across all possible information structures. First, I address this question from a global perspective and then generalize the analysis to allow for localized informational robustness.
