Revealed Preference and Econometrics

这个项目探讨了我们是否可以从经验上检验人们以经济理性的方式做出决定的假设。该项目将众所周知的揭示偏好的微观经济学概念与非参数需求估计的最新结果相结合。该研究团队结合了经济理论的新研究、新计算工具的开发和新的统计检验方法，包括新的检验统计、估计这些统计分布的方法和构建置信区间的方法。这些方法都是为了应用于大型数据集。该项目通过建立将两个截然不同的经济学领域结合在一起的思想和方法，开辟了新的领域。研究结果将允许使用非常大的数据集对关键的经济假设进行实证检验，而由于计算能力的提高，这种方法现在才成为可能。在这个项目中开发的方法将对许多其他目的有用；例如，企业和政府将能够使用这些方法从观察到的对现有产品的购买决策中推断出对新产品的需求。

This project explores whether or not we can empirically test the assumption that people make decisions in economically rational ways. The project combines the well-known microeconomic concept of revealed preference with recent results on nonparametric demand estimation. The research team combines new research in economic theory, the development of new computational tools, and new statistical testing methods that include new test statistics, ways to estimate the distribution of these statistics, and ways to construct confidence intervals. The methods are all intended for application to large data sets.The project breaks new ground by building ideas and methods that bring together two very different areas of economics. The results will allow for the empirical testing of key economic hypotheses using very large data sets in ways that are only now possible because of increased computing power. The methods developed in this project will be useful for many other purposes; for example, businesses and governments will be able to use these methods to infer demand for new products from observed purchase decisions about existing products.
