关于美国近期经济不平等加剧的争论主要有两种立场。 “工作与技能不匹配”的论点将不平等的加剧归因于高技能、高工资工作数量的增长，从而将低技能工人抛在了后面。相比之下，“两极分化”理论认为，服务业的转变导致高工资和低工资工作数量的增长，而中间工资工作的数量下降。分配不平等的标准汇总衡量标准无法区分这些对就业增长发生地点的描述。我们提出了新的测量方法，提供有关收入分配变化的摘要和详细信息以及统计推断框架。利用当前人口调查 (CPS) 中 1967 年至 1987 年年收入的数据，我们发现分配不平等的趋势因种族、性别和时间而异。虽然证据为两极分化论点提供了更多支持，但如果要解释这里观察到的不平等变化的变化，这篇论文还需要完善。
Two positions dominate the debate over the recent increases in economic inequality in the United States. The "job-skill mismatch" thesis attributes rising inequality to growth in the number of high-skill, high-wage jobs that leaves less-skilled workers behind. The "polarization" thesis, in contrast, argues that the service shift generates growth in the number of both high-wage and low-wage jobs, and declines in the middle. Standard summary measures of distributional inequality cannot discriminate between these depictions of where job growth is occurring. We propose new methods for measurement that provide both summary and detailed information about the distributional shifts in earnings and aframework for statistical inference. Using data from the Curent Population Survey (CPS) on yearly earnings from 1967 to 1987, we show that the trends in distributional inequality vary considerably by race, gender, and time. While the evidence provides more support for the polarization argument, this thesis needs refinement if it is to account for the variations in changing inequality observed here.
