Tempting goods, self-control fatigue, and time preference in consumer dynamics
构建了一个有限自我控制下的消费者动态模型，强调自我调节的疲劳特性，分析了诱惑商品消费如何受财富、自我控制疲劳和压力冲击的影响，并比较了不同认知类型消费者的长期自我控制差异。
Abstract We propose a dynamic model of consumer behavior under limited self-control, emphasizing the fatiguing nature of self-regulation. The temptation theory is extended in a two-good setting with tempting and non-tempting goods, where self-regulation in moderating tempting good consumption depreciates mental capital (willpower). The resulting non-homothetic feature of consumer preferences helps describe self-regulatory behavior in such an empirically relevant way that it depends on the nature of the tempting good (luxury or inferior) and on consumer wealth. First, richer consumers are more self-indulgent and impatient in consuming tempting luxuries, whereas less so in consuming tempting inferiors: impatience is marginally increasing in wealth for jewels whereas decreasing for junk foods. Second, self-control fatigue weakens implied patience for tempting good consumption. Third, upon a stressful shock, with the resulting increasing scarcity of willpower, self-indulgence and impatience for tempting good consumption increase over time. Fourth, naive consumers, unaware of the willpower constraint, display weaker self-control in the long run than sophisticated consumers in the same wealth class would do.
