摘要翻译：
两个多世纪以来，关于公平收入不平等的问题一直是经济学和政治哲学中一个重要的开放式问题，只有罗尔斯、诺齐克和德沃金等人提出的定性答案。最近，我们通过发展一个博弈论框架，为理想的自由市场社会提供了一个定量的答案，该框架证明了理想的不等式是均衡状态下收入的对数正态分布。在本文中，我们发展了另一种方法，使用纳什讨价还价解决方案(NBS)框架，也得到了同样的结论。尽管结论是相同的，但是，新的方法揭示了NBS的真实本质，几十年来，NBS一直受到相当大的关注。经济学家们一直想知道国家统计局的经济意义或目的。虽然有些人暗示了它的公平属性，但我们更确凿地表明，它完全是关于公平的。由于熵的本质也是公平性，我们看到了纳什积与大量理性经济人的熵之间有趣的联系。

英文摘要：
The question about fair income inequality has been an important open question in economics and in political philosophy for over two centuries with only qualitative answers such as the ones suggested by Rawls, Nozick, and Dworkin. We provided a quantitative answer recently, for an ideal free-market society, by developing a game-theoretic framework that proved that the ideal inequality is a lognormal distribution of income at equilibrium. In this paper, we develop another approach, using the Nash Bargaining Solution (NBS) framework, which also leads to the same conclusion. Even though the conclusion is the same, the new approach, however, reveals the true nature of NBS, which has been of considerable interest for several decades. Economists have wondered about the economic meaning or purpose of the NBS. While some have alluded to its fairness property, we show more conclusively that it is all about fairness. Since the essence of entropy is also fairness, we see an interesting connection between the Nash product and entropy for a large population of rational economic agents.
