中文摘要
摘要 本文提出了一种基于一国进口内容来估计该国国内不平等的新方法。如果偏好是非位似的,一国的富人与穷人便具有不同的消费结构。因此,进口可以提供有关一国收入分配的信息。贸易数据在全球范围内的可得性,使我们能够用一种单一、透明且可比的方法,对大量国家随时间的不平等进行估计。与传统数据相比,我们对发展中国家的覆盖尤其充分。我们提供了一系列稳健性检验与交叉验证,结果表明本方法表现良好。
Abstract
Abstract This paper develops a novel method to estimate inequality within a country based on what the country imports. If preferences are non-homothetic, rich and poor individuals of a country have different consumption profiles. Imports can thus inform about the income distribution in a country. The global availability of trade data allows us to estimate inequality using a single transparent and comparable method for a large sample of countries over time. Compared to conventional data, we feature an especially good coverage of developing countries. We provide a number of robustness checks and cross-validation exercises that show the good performance of our method.
