我们提出了一个有限自我控制下的消费者行为的动态模型，强调自我调节的疲劳性。诱惑理论在两种商品的情况下进行了扩展，其中包括诱人的商品和非诱人的商品，在这种情况下，控制诱人的良好消费的自我调节会贬低精神资本(意志力)。由此产生的消费者偏好的非同质性特征有助于以一种与经验相关的方式描述自我调节行为，这取决于诱人的商品(奢侈品或劣质商品)的性质和消费者的财富。首先，更富有的消费者在消费诱人的奢侈品时更加自我放纵和不耐烦，而在消费诱人的次要物品时则不那么：不耐烦的财富在珠宝方面略有增加，而在垃圾食品方面却在减少。其次，自我控制疲劳削弱了人们对吸引良好消费的隐含耐心。第三，在压力过大的冲击下，随着时间的推移，意志力的日益匮乏、自我放纵和对吸引良好消费的不耐烦增加。第四，天真的消费者没有意识到意志力的限制，从长远来看，他们表现出的自控力弱于同一财富阶层中成熟的消费者。
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.
