摘要:
为了在需求数据中确定价格变化的福利含义,我们引入了一种关于价格的显示性偏好关系。我们证明,该关系中不存在循环刻画了一个在消费效用与支出负效用之间进行权衡的消费者。我们的模型适用于分析消费者对所有可得商品的严格子集的需求;它还可以扩展到具有离散商品和非线性价格的情形。为说明其用途,我们将该模型应用于一个单主体数据集和一个具有重复截面结构的数据集。我们提出了一种对部分识别参数进行线性假设检验的新方法,以估计在后一应用中因价格变化而被显示为福利改善的人口比例。这一新技术可以更广泛地用于非参数反事实分析。
英文摘要:
To determine the welfare implications of price changes in demand data, we introduce a revealed preference relation over prices. We show that the absence of cycles in this relation characterizes a consumer who trades off the utility of consumption against the disutility of expenditure. Our model can be applied whenever a consumer's demand over a strict subset of all available goods is being analyzed; it can also be extended to settings with discrete goods and nonlinear prices. To illustrate its use, we apply our model to a single-agent data set and to a data set with repeated cross-sections. We develop a novel test of linear hypotheses on partially identified parameters to estimate the proportion of the population who are revealed better off due to a price change in the latter application. This new technique can be used for nonparametric counterfactual analysis more broadly.
