Temptation with Uncertain Normative Preferences

We model a decision maker who anticipates being a ected by temptation but is also uncertain about what is normatively best. Our model is an extended version of Gul and Pesendorfer's (2001) where there are three time periods: in the ex-ante period the agent chooses a set of menus, in the interim period she chooses a menu from this set, and in the nal period she chooses from the menu. We posit axioms from the ex-ante perspective. Our main axiom on preference states that the agent prefers to have the option to commit in the interim period. Our representation is a generalization of Dekel et al.'s (2009) and identi es the agent's multiple normative preferences and multiple temptations. We also characterize the uncertain normative preference analogue to the representation in Stovall (2010). Finally, we characterize the special case where normative preference is not uncertain. This special case allows us to uniquely identify the representations of Dekel et al. (2009) and Stovall (2010).
