Abstract: We analyze the rationality of a Decision Maker (DM) who chooses from lists of sets of alternatives. A new class of choice functions, representing the DM's choice-behavior, and a new rationality axiom are proposed and studied. We show that a property, that we call No-Regret suggests that alternatives disregarded as of no interest for the DM be ignored, is a rationality criterion that encompasses some compelling postulates of the classical choice model and extends them to the proposed general framework of choice from lists of sets of alternatives.
