财富规模分布的广义统计模型

A generalized statistical model for the size distribution of wealth

F. Clementi, M. Gallegati, G. Kaniadakis

摘要:

在最近的一篇论文在这个杂志[J.统计。Mech.(2009)P02037]我们提出了一个新的、物理激励的分布函数,用于在k-广义统计力学的框架中对个人收入进行建模。2003年,根据美国个人收入的实际数据,对k-广义分布的表现进行了检验。在本文中,我们扩展了我们以前的模型,以便能够解释财富的分配。给出了广义财富分布模型的概率函数和不等式测度的封闭形式。为了检验所提出的模型的有效性,我们分析了1984年至2009年的美国家庭财富分布,并得出了优于文献中已知的任何其他模型的数据的良好协议。

英文摘要:

In a recent paper in this journal [J. Stat. Mech. (2009) P02037] we proposed a new, physically motivated, distribution function for modeling individual incomes having its roots in the framework of the k-generalized statistical mechanics. The performance of the k-generalized distribution was checked against real data on personal income for the United States in 2003. In this paper we extend our previous model so as to be able to account for the distribution of wealth. Probabilistic functions and inequality measures of this generalized model for wealth distribution are obtained in closed form. In order to check the validity of the proposed model, we analyze the U.S. household wealth distributions from 1984 to 2009 and conclude an excellent agreement with the data that is superior to any other model already known in the literature.
