在Gul和Pesendorfer(Econometrica 69(6)：1403-1435,2001)一案中，决策者在面临菜单选择时，根据其承诺效用扣除自我控制成本的最大价值来评估每个菜单。本文对模型进行了扩展，使这一最大值受到自我控制成本不能超过决策者意志力存量的约束。我们刻画的五个公理中有四个与他们的定理3相同，只是独立性公理仅限于菜单的一个子集。我们增加了一个新的公理，将意志力作为一种有限的(认知)资源来管理，在这种资源中，可用的“股票”不会因菜单而异。在我们的描述中，菜单中满足WARP的选择揭示了承诺和诱惑效用之间的持续权衡。然而，正是菜单偏好的不连续性(以及菜单内选项的偏差)揭示了sw(以诱惑效用单位衡量)，从而允许对个人的自我控制进行行为上有意义的比较测量。
In Gul and Pesendorfer (Econometrica 69(6):1403–1435, 2001), a decision-maker, when facing a choice among menus, evaluates each menu in terms of the maximum value of its commitment 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-maker’s stock of willpowerw. Four of the five axioms of our characterization are as in their Theorem 3 except that the independence axiom is restricted to a subset of menus. We add one new axiom to regulate willpower as a limited (cognitive) resource in which the available “stock” does not vary across menus. In our characterization, choices within menus that satisfy WARP reveal a constant trade-off between commitment and temptation utilities. However, it is the discontinuity of preferences over menus (along withviolationsof WARP for choices within menus) thatrevealsw(measured in units of temptation utility), allowing for a behaviorally meaningful comparative measure of self-controlacrossindividuals.
