基于Fourier的不等式指数
On Fourier-based inequality indices
摘要:
不平等指数最初是为了衡量财富的异质性而制定的,是在单位区间内取值的量化分数,零分代表完全平等。在本文中,我们提请注意一个新的不等式指数,基于傅立叶变换,它表现出一些有趣的属性,使它在应用中非常有前途。作为一个副产品,它表明,其他的不平等措施,包括基尼系数和彼得拉指数可以卓有成效地表示在傅立叶变换,它允许启发的性质,在一个新的和简单的方式。
英文摘要:
Originally developed for measuring the heterogeneity of wealth measures, inequality indices are quantitative scores that take values in the unit interval, with the zero score characterizing perfect equality. In this paper, we draw attention to a new inequality index, based on the Fourier transform, which exhibits a number of interesting properties that make it very promising in applications. As a by-product, it is shown that other inequality measures, including Gini and Pietra indices can be fruitfully expressed in terms of the Fourier transform, which allows to enlighten properties in a new and simple way.
