Lorenz Densities and Lorenz Curves
2014Lorenz curves and Lorenz densities are introduced for real-valued random variables with finite and strictly positive expectation. Gastritic’s definition of a Lorenz curve is used. Basic properties of Lorenz curves are given as well as approximation results.

Abstract A family of elliptic Lorenz curves is proposed for fitting grouped income data. The associated distribution and density functions are displayed together with the Gini indices. Estimation procedures are discussed. Comparisons are made with alternative models using Australian 1967–68 income data.

The Lorenz dominance criterion is the centre piece of inequality analysis. Yet, the appeal of this criterion, which requires considering Lorenz curves in their entirety, is undermined by the practical problem that many sample Lorenz curves intersect in the tails.

Abstract A new class of Lorenz curves is proposed by a mixture of an initial Lorenz curve with a known probability density function, assuming the existence of some heterogeneity factor. Three new mixture curves are proposed and numerical comparisons are done.

The Lorenz Curve and the Concentration Curve
2012The Lorenz and the concentration curves play important roles in the areas of GMD and the related measures such as Gini covariance, Gini correlation, Gini regression, and more. In this chapter we introduce the curves, discuss their properties, and show their connections to the Gini world. In addition, in order to be able to analyze the parallel concepts

This is a unique account of the role played by 58 figures and diagrams commonly used in economic theory. These cover a large part of mainstream economic analysis, both microeconomics and macroeconomics and also general equilibrium theory.

Inference for Lorenz curve orderings [PDF]
The Econometrics Journal, 1999 In this paper we consider the issue of performing statistical inference for Lorenz curve orderings. This involves testing for an ordered relationship in a multivariate context and making comparisons among more than two population distributions. Our approach is to frame the hypotheses of interest as sets of linear inequality constraints on the vector of

Asymptotic confidence bands for the Lorenz and Bonferroni curves based on the empirical Lorenz curve
Journal of Statistical Planning and Inference, 1998Abstract We construct asymptotic confidence bands for the Lorenz and Bonferroni curves that are fundamental tools for analyzing data arising in economics and reliability. The width of the obtained confidence bands is regulated by weight functions depending on the available information about the underlying distribution function.

We study the Generalized Lorenz curves of the minima of samples from a random variable. These Lorenz curves can be used to compare distributions in terms of their variability and define coherent risk measures. The dual Lorenz curves of the maxima of samples from the random variable are also considered.

Abstract This paper presents a functional form, linear in the parameters, to deal with income distribution and Lorenz curves. The function is fitted to the Brazilian income distribution. Data standard deviations were estimated from year-to-year variation of the income share.
