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 ...

Ranking Intersecting Lorenz Curves [PDF]
Social Choice and Welfare, 2004 This paper is concerned with the problem of ranking Lorenz curves in situations where the Lorenz curves intersect and no unambiguous ranking can be attained without introducing weaker ranking criteria than first-degree Lorenz dominance. To deal with such

Quantum Relative Lorenz Curves [PDF]
Physical Review A, 2017 The theory of majorization and its variants, including thermomajorization, have been found to play a central role in the formulation of many physical resource theories, ranging from entanglement theory to quantum thermodynamics.

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.

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.

Single Crossing Lorenz Curves and Inequality Comparisons [PDF]
Mathematical Social Sciences, 2004 Since the order generated by the Lorenz criterion is partial, it is a natural question to wonder how to extend this order. Most of the literature that is concerned with that question focuses on local changes in the income distribution.

Robust Lorenz Curves: A Semiparametric Approach [PDF]
, 2001 Lorenz curves and second-order dominance criteria are known to be sensitive to data contamination in the right tail of the distribution. We propose two ways of dealing with the problem: (1) Estimate Lorenz curves using parametric models for income ...

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.
