Uncovered set choice rules. (English) Zbl 1163.91348
Summary: I study necessary and sufficient conditions for a choice function to be rationalized in the following sense: there exists a total asymmetric relation \(T\) (a tournament) such that, for each feasible (finite) set, the choice set coincides with the uncovered set of \(T\) restricted to that feasible set. This notion of ‘maximization’ offers testable restrictions on observable choice behavior.
