Truncation Bias and the Ordinal Evaiuation of Income Inequality
利用洛伦兹优势分析，考察了最高收入编码对跨期美国收入不平等序数评价的影响，通过调整截断偏差并运用统计推断，发现自1985年起该偏差显著影响不平等排序。
Lorenz dominance analysis is used to examine the effect of top-coding on the ordinal evaluation of U.S. income inequality across time. Current Population Survey microdata are adjusted for truncation bias, and statistical inference procedures are used to examine biennial changes in unadjusted and adjusted Lorenz curves. Beginning in 1985, the truncation bias has a significant effect on ordinal rankings of income inequality.
