How Much Inequality Can we Explain? A Methodology and an Application to the United States
提出两个类似回归R2的简单指标，衡量人口特征对不平等的解释程度，并用美国PSID收入数据演示多种分解方法。
We develop two simple measures of how much inequality is explained by individual population characteristics or groups of characteristics, analogous to R2 in regression analysis. We investigate the measures' empirical implementation using several alternative theoretically consistent approaches to inequality decomposition. Results are illustrated using US PSID income data.
