论文摘要
众所周知，收入不平等对经济体系产生负面影响，因此已经辩论了一百年或更长时间。已经提出了许多想法来量化收入不平等，而Gini系数是普遍的指数。但是，GINI系数中完美平等的概念相当理想主义，并且无法就是否需要政府干预来调整收入不平等的情况提供现实的指导。在本文中，我们首先提出了更现实和可行的收入平等的概念，从而最大化了总体社会福利。然后，我们表明，可以使用Sigmoid福利功能和Boltzmann收入分配来对代表可行平等的最佳收入分配进行建模。最后，我们对四个国家进行了经验分析，并证明了如何评估最佳收入分配。我们的结果表明，可行的收入平等可以用作政府政策和干预措施的实用指南。
Income inequality is known to have negative impacts on an economic system, thus has been debated for a hundred years past or more. Numerous ideas have been proposed to quantify income inequality, and the Gini coefficient is a prevalent index. However, the concept of perfect equality in the Gini coefficient is rather idealistic and cannot provide realistic guidance on whether government interventions are needed to adjust income inequality. In this paper, we first propose the concept of a more realistic and feasible income equality that maximizes total social welfare. Then we show that an optimal income distribution representing the feasible equality could be modeled using the sigmoid welfare function and the Boltzmann income distribution. Finally, we carry out an empirical analysis of four countries and demonstrate how optimal income distributions could be evaluated. Our results show that the feasible income equality could be used as a practical guideline for government policies and interventions.
