Testable Implications of Models of Intertemporal Choice: Exponential Discounting and Its Generalizations
给出了指数贴现凹效用模型及其推广的显示偏好刻画，提供非参数检验方法，并应用于两个实验数据，揭示了传统参数方法未发现的新见解。
We present revealed-preference characterizations of the most common models of intertemporal choice: the model of exponentially discounted concave utility, and some of its generalizations. Our characterizations take consumption data as primitives, and provide nonparametric revealed-preference tests. We apply our tests to data from two recent experiments and find that our axiomatization delivers new insights and perspectives on datasets that had been analyzed by traditional parametric methods.
