Zenga Distribution and Inequality Ordering

Francesco Porro

Communications in Statistics - Theory and Methods, 2015, vol. 44, issue 18, 3967-3977

Abstract: The aim of this article is to establish an ordering related to the inequality for the recently introduced Zenga distribution. In addition to the well-known order based on the Lorenz curve, the order based on I(p) curve is considered. Since the Zenga distribution seems to be suitable to model wealth, financial, actuarial, and, especially, income distributions, these findings are fundamental in the understanding of how parameter values are related to inequality. This investigation shows that for the Zenga distribution, two of the three parameters are inequality indicators.
