从历史上看，三月当期人口调查（CPS）越来越多地捕捉到了所有收入来源分配的上尾。加上顶部编码的时间一致性问题，这意味着公共使用和限制访问CPS的用户将低估早期工资收入和收入不平等的水平，并夸大其随时间的增长。我们通过使用第二类广义beta分布对全职、全年工人的个人收入进行建模来解决这个问题，从估计的参数中计算基尼系数，并将其与过去的发现进行比较。
Over its history, the March Current Population Survey (CPS) has increasingly captured the upper tail of the distribution of all sources of income. This, together with time-consistency problems in top coding, means that users of both the public-use and restricted-access CPS will understate the level of wage earnings and income inequality in earlier years and overstate their growth over time. We address this problem by modeling the personal earnings of full-time, full-year workers using the generalized beta distribution of the second kind, calculating Gini coefficients from the estimated parameters, and comparing them with past findings.
