摘要翻译：
本文对过去十年来物理学家对收入分配的实证研究进行了双管齐下的批评。他们的发现依赖于对观察到的归一化收入分布的图形分析。两个中心的观察得出结论，大多数收入是指数分布的，但无论是每一个单独的证据，还是它们同时进行的观察，都没有有力地证明热和超热混合物比合理的替代方案更适合所观察到的收入分布。采用流行的拟合度量的形式分析表明，虽然具有幂律尾部的指数分布比经济学家通常假设的对数正态分布更好地拟合IRS收入数据，但通过增加对数正态分布分量可以进一步改善热和超热混合物的拟合。本文探讨了收入的热分配和超热分配以及膨胀混合物的经济含义。

英文摘要：
This paper offers a two-pronged critique of the empirical investigation of the income distribution performed by physicists over the past decade. Their finding rely on the graphical analysis of the observed distribution of normalized incomes. Two central observations lead to the conclusion that the majority of incomes are exponentially distributed, but neither each individual piece of evidence nor their concurrent observation robustly proves that the thermal and superthermal mixture fits the observed distribution of incomes better than reasonable alternatives. A formal analysis using popular measures of fit shows that while an exponential distribution with a power-law tail provides a better fit of the IRS income data than the log-normal distribution (often assumed by economists), the thermal and superthermal mixture's fit can be improved upon further by adding a log-normal component. The economic implications of the thermal and superthermal distribution of incomes, and the expanded mixture are explored in the paper.
