A Dual-Self Model of Impulse Control
提出一个简单的双自我模型，统一解释了准双曲线贴现模型中的时间不一致性、拉宾风险厌恶悖论、自我控制成本导致的过度延迟以及认知负荷增加诱惑抵抗难度等实证规律。
We propose that a simple “dual-self” model gives a unified explanation for several empirical regularities, including the apparent time inconsistency that has motivated models of quasi-hyperbolic discounting and Rabin's paradox of risk aversion in the large and small. The model also implies that self-control costs imply excess delay, as in the O'Donoghue and Rabin models of quasi-hyperbolic utility, and it explains experimental evidence that increased cognitive load makes temptations harder to resist. The base version of our model is consistent with the Gul-Pesendorfer axioms, but we argue that these axioms must be relaxed to account for the effect of cognitive load.
