Costly Self-Control and Limited Willpower

Author

Abstract

In Gul and Pesendorfer (2001), a decision-maker, when facing a choice among menus, evaluates each menu in terms of the maximum value of its normative utility net of self-control costs. This paper extends the model such that this maximum is constrained by the condition that the cost of self-control cannot exceed the decision-makerís stock of willpower w. In our characterization, choices within menus that satisfy the weak axiom of revealed preferences (WARP) reveal a constant trade-off between normative and temptation utilities. However, it is the discontinuity of preferences over menus (along with violations of WARP for choices within menus) that reveals w (measured in units of temptation utility), allowing for a behaviorally meaningful comparative measure of self-control across individuals.
