Non-parametric Analysis of Time-Inconsistent Preferences
用显示偏好方法刻画准双曲贴现模型，利用家庭消费面板数据检验时间不一致行为，发现准双曲模型比替代模型更能解释行为，并估计了时间偏好和贴现函数的联合分布。
Abstract This article provides a revealed preference characterisation of quasi-hyperbolic discounting which is designed to be applied to readily available expenditure surveys. We describe necessary and sufficient conditions for the leading forms of the model and also study the consequences of the restrictions on preferences popularly used in empirical lifecycle consumption models. Using data from a household consumption panel dataset, we explore the prevalence of time-inconsistent behaviour. The quasi-hyperbolic model provides a significantly more successful account of behaviour than the alternatives considered. We estimate the joint distribution of time preferences and the distribution of discount functions at various time horizons.
