18 p, 299.0 KB On a property of Lorenz curves with monotone elasticity and its application to the study of inequality by using tax data / Sordo Díaz, Miguel Ángel (Universidad de Cádiz. Departamento de Estadística e Investigación Operativa) ; Berihuete Macías, Ángel (Universidad de Cádiz. Departamento de Estadística e Investigación Operativa) ; Ramos González, Carmen Dolores (Universidad de Cádiz. Departamento de Estadística e Investigación Operativa) ; Ramos Romero, Héctor Manuel (Universidad de Cádiz. Departamento de Estadística e Investigación Operativa)
The Lorenz curve is the most widely used graphical tool for describing and comparing inequality of income distributions. In this paper, we show that the elasticity of this curve is an indicator of the effect, in terms of inequality, of a truncation of the income distribution. [...]

8 p, 112.1 KB Analysis of inequality in fertility curves fitted by gamma distributions / Ramos, Héctor M. ; Peinado, Antonio ; Ollero, Jorge ; Ramos, María G. (Universidad de Cádiz. Departamento de Estadística e Investigación Operativa)
The aim of this paper is to analyse fertility curves from a novel viewpoint, that of inequality. Through sufficient conditions that can be easily verified, we compare inequality, in the Lorenz and Generalized Lorenz sense, in fertility curves fitted by gamma distributions, thus achieving a useful complementary instrument for demographic analysis.

(Universidad de Cádiz. Departamento de Estadística e Investigación Operativa) ; Ramos, Carmen D. (Universidad de Cádiz. Departamento de Estadística e Investigación Operativa)
We examine the conditions under which unanimous poverty rankings of income distributions can be obtained for a general class of poverty indices. The "per-capita income gap" and the Shorrocks and Thon poverty measures are particular members of this class. [...]
