论文摘要
我们介绍了最近提出的不平等指数Zenga指数的社会福利含义。我们的建议是通过Son（2011）和Kakwani and Son（2019）的最新工作论文的开创性书来得出的。我们根据Lorenz曲线和Gini系数以及Bonferroni指数将基于Zenga的方法与经典方法进行比较。我们表明，基于Zenga统一曲线的社会福利规范提出了一些与众不同的索引。此处介绍的社会福利规范对Zenga指数如何评估分布中的不平等的方式有了更深入的了解。
We introduce the social welfare implications of the Zenga index, a recently proposed index of inequality. Our proposal is derived by following the seminal book by Son (2011) and the recent working paper by Kakwani and Son (2019). We compare the Zenga based approach with the classical one, based on the Lorenz curve and the Gini coefficient, as well as the Bonferroni index. We show that the social welfare specification based on the Zenga uniformity curve presents some peculiarities that distinguish it from the other considered indexes. The social welfare specification presented here provides a deeper understanding of how the Zenga index evaluates the inequality in a distribution.
