The first moment of income density functions and estimation of single-parametric Lorenz curves. [PDF]
PLoS ONE, 2022 This paper discusses the first moment, i.e., the mean income point, of income density functions and the estimation of single-parametric Lorenz curves. The mean income point is implied by an income density function and associated with a single-parametric ...

Lorenz curves of urban and rural health care expenditure in Colombia: analysis of a cohort of 4.6 million patients [PDF]
Health Economics ReviewIn Colombia, health expenditure is highly concentrated, with a small portion of the population incurring most costs, particularly in rural areas. Men show greater inequality than women.

Estimating Lorenz and Concentration Curves [PDF]
The Stata Journal, 2016 Lorenz and concentration curves are widely used tools in inequality research. In this article, I present a new command, lorenz, that estimates Lorenz and concentration curves from individual-level data and, optionally, displays the results in a graph.

Domiciliary dental care coverage in Taiwan: An assessment of provider participation and geographic distribution using the universal health coverage framework [PDF]
Journal of Dental SciencesBackground/purpose: Universal health coverage (UHC) ensures access to needed health services without financial hardship. While Taiwan has achieved near-universal coverage for most medical services, domiciliary dental care (DDC) for people with mobility ...

Re-Expression of the Lorenz Asymmetry Coefficient on the Rotated and Right-Shifted Lorenz Curve of Leaf Area Distributions [PDF]
PlantsThe Gini coefficient, while widely used to quantify inequality in biological size distributions, lacks the capacity to resolve directional asymmetry inherent in Lorenz curves, a critical limitation for understanding skewed resource allocation strategies.

A data science based standardized Gini index as a Lorenz dominance preserving measure of the inequality of distributions. [PDF]
PLoS ONE, 2017 The Gini index is a measure of the inequality of a distribution that can be derived from Lorenz curves. While commonly used in, e.g., economic research, it suffers from ambiguity via lack of Lorenz dominance preservation.

Group averaging and the Gini deviation
RUDN Journal of Economics, 2021 It is known that partitioning a society into groups with subsequent averaging in each group decreases the Gini coefficient. The resulting Lorenz function is piecewise linear.

Asymptotic Results in Broken Stick Models: The Approach via Lorenz Curves
Mathematics, 2020 A stick of length 1 is broken at random into n smaller sticks. How much inequality does this procedure produce? What happens if, instead of breaking a stick, we break a square? What happens asymptotically?

Lorenz-generated bivariate Archimedean copulas
Dependence Modeling, 2020 A novel generating mechanism for non-strict bivariate Archimedean copulas via the Lorenz curve of a non-negative random variable is proposed. Lorenz curves have been extensively studied in economics and statistics to characterize wealth inequality and ...
