The parameterization of income distributions using Lorenz Curves is a useful technique to analyze the characteristics of income inequality within a given population. It provides a way of describing how data are generated, why the level of inequality is what it is, and how these factors impact...

This paper defines and characterizes the concept of an increase in inverse downside inequality and show that, when the Lorenz curves of two income distributions intersect, how the change from one distribution to the other is judged by an inequality index exhibiting inverse downside inequality...

The inequality dataset compiled in the 1990s by the World Bank and extended by the United Nations has been both widely used and strongly criticized. The criticisms raise questions about conclusions drawn from secondary inequality datasets in general. The authors develop techniques to deal with...

Reranking in the move from one income distribution to another makes it impossible to infer from changes in Lorenz and generalised Lorenz curves how income growth among those toward the bottom of the initial income distribution compares to that among those toward the top, and whether there has...

We propose a nonparametric estimator of the Lorenz curve that satisfies its theoretical properties, including monotonicity and convexity. We adopt a transformation approach that transforms a constrained estimation problem into an unconstrained one, which is estimated nonparametrically. We...

In this paper we compare the labor market performance of Israeli students who graduated from one of the leading universities, Hebrew University (HU), with those who graduated from a professional undergraduate college, College of Management Academic Studies (COMAS). Our results support a model in...

This essay outlines the exact definition of “Equality” and “Inequality” in economics. The discussion moves forward to review concepts of ranking of orderings and methodology of constructing Indices of Inequality with an emphasis on Lorenz Orderings. We also discuss the possibility of...

This paper studies the nature of social welfare orders on infinite utility streams, satisfying the efficiency principle known as Monotonicity and the consequentialist equity principle known as Strong Equity. It provides a complete characterization of domain sets for which there exists such a...
