Indecisiveness aversion and preference for commitment
AbstractWe present a system of behavioral axioms for preferences over menus that is motivated by three assumptions. First, the decision maker is uncertain ex ante (i.e. at the time of choosing a menu) about her ex post (i.e. at the time of choosing an option within her chosen menu) preferences over options, and she anticipates that this subjective uncertainty will only resolve after the ex post stage. Second, she is averse to ex post indecisiveness (i.e. to having to choose between options that she cannot rank with certainty). Third, when evaluating a menu she discards options that are dominated (i.e. inferior to another option whatever her ex post preferences may be) and restricts attention to the undominated ones. Under these assumptions, the decision maker has a preference for commitment in the sense of preferring menus with fewer undominated alternatives. We derive a representation in which the decision maker's uncertainty about her ex post preferences is captured by means of a subjective state space, which in turn determines which options are undominated in a given menu, and in which the decision maker fears, whenever indecisive, to choose an option that will turn out to be the worst (undominated) one according to the realization of her ex post preferences.
