Preferences may arise from regret, i.e., from comparisons with alternatives forgone by the decision maker. We ask whether regret-based behavior is consistent with non-expected utility theories of transitive choice and show that the answer is no. If choices are governed by ex ante regret and...

The paper proposes a method of transforming a possibly cyclic preference relation of a decision maker into a transitive binary relation, which is called the transitive core. The characterizing properties of such a transformation is given. In addition, the transitive core is applied to...
