The Endogenous Determination of Time Preference
构建了一个消费者努力降低未来效用贴现的模型，分析财富、死亡率、成瘾、不确定性等因素如何影响时间偏好程度，并讨论该模型对消费、储蓄、均衡和不平等动态的解释力。
We model a consumer's efforts to reduce the discount on future utilities. Our analysis shows how wealth, mortality, addictions, uncertainty, and other variables affect the degree of time preference. In addition to working out many implications of the model, we discuss evidence on consumption, savings, equilibrium, and the dynamics of inequality. We claim that most ofthat evidence is consistent with the predictions of our approach.
