Inequality and Economic Growth: The Empirical Relationship Reconsidered in the Light of Comparable Data
指出以往研究收入不平等与经济增长关系的实证工作使用了不一致的衡量数据,并发现当用一致方式衡量收入不平等时,两者间的显著负相关不再稳健;但基于发展中国家的样本,用一致衡量的支出数据与经济增长间存在显著负相关。
All of the recent empirical work on the relationship between income inequality and economic growth has used inequality data that are not consistently measured. This paper argues that this is inappropriate and shows that the significant negative correlation often found between income inequality and growth across countries is not robust when income inequality is measured in a consistent manner. However, evidence is found of a significant negative correlation between consistently measured inequality of expenditure data and economic growth for a sample of developing countries. Outline 1.
