Revealed Preference and Econometrics

这个项目探讨了我们是否可以实证检验人们以经济理性的方式做出决策的假设。 该项目结合了著名的微观经济学的概念，显示偏好与非参数需求估计的最新成果。 该研究团队结合了经济理论的新研究，新计算工具的开发以及新的统计测试方法，包括新的测试统计量，估计这些统计量分布的方法以及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。该项目通过构建将两个非常不同的经济学领域结合在一起的思想和方法来开辟新天地。 这些结果将允许使用非常大的数据集对关键经济假设进行实证检验，而这种检验只有在现在才有可能，因为计算能力的提高。 本项目中开发的方法将用于许多其他目的;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.
