摘要翻译：
经济学中的一个重要问题是人们如何在未来的不同支付之间做出选择。经典的规范模型预测决策者对较晚支付的折扣与较早支付的折扣之间的时间是指数函数。描述性模型使用非指数函数来拟合观察到的行为现象，如偏好反转。在这里，我们提出了一个贴现模型，符合标准的选择公理，其中决策者最大限度地增加他们的财富增长率。该模型的四个规范产生了四种形式的折扣--无折扣、指数、双曲线和指数与双曲线的混合--其中两种预测偏好反转。我们的模型不需要假设行为偏差或支付风险。

英文摘要：
  An important question in economics is how people choose between different payments in the future. The classical normative model predicts that a decision maker discounts a later payment relative to an earlier one by an exponential function of the time between them. Descriptive models use non-exponential functions to fit observed behavioral phenomena, such as preference reversal. Here we propose a model of discounting, consistent with standard axioms of choice, in which decision makers maximize the growth rate of their wealth. Four specifications of the model produce four forms of discounting -- no discounting, exponential, hyperbolic, and a hybrid of exponential and hyperbolic -- two of which predict preference reversal. Our model requires no assumption of behavioral bias or payment risk.
