Corrigendum to "Rationality and coherent theories of strategic behavior" [J. Econ. Theory 70 (1) (1996) 1-31]
We show, by means of a counterexample, that Propositions 3, 4, and 7 in Gul (1996) [G96] are incorrect. Our example is also a counterexample to Lemma 1 in G96, which is the basis for the proofs of these propositions. We provide insight for the source of the problem in the definition of a perfect τ-theory in G96, and then offer a modification that restores these results in G96.
