On Dagum’s Decomposition of the Gini Coefficient [PDF]

To measure the contributions to inequality from population subgroups, the Gini coefficient is often decomposed into inequality within groups, inequality between groups and a residual term arising from the overlapping of income distributions from ...

Deniers and Compliers: Unpacking the Heterogeneous Effectiveness of U.S. Stay‐at‐Home Mandates During the COVID‐19 Pandemic

Journal of Applied Econometrics, EarlyView.
ABSTRACT While existing work shows COVID‐19 stay‐at‐home (SAH) policies decreased mobility on average, we lack evidence regarding heterogeneity in policy effectiveness across US counties. To uncover potential heterogeneity, we implement a novel two‐stage approach.

Distributional Limits and GINI Coefficient. [PDF]

This paper examines the Gini (1912) coefficient of concentration using the framework set out by Dalton (1920) for evaluating a measure of inequality. Particular attention is paid to limited distributions and the associated concept of 'perfect inequality'.

Using the Gini coefficient with BIOLOG substrate utilisation data to provide an alternative quantitative measure for comparing bacterial soil communities [PDF]

, 1997
A measure quantifying unequal use of carbon sources, the Gini coefficient (G), has been developed to allow comparisons of the observed functional diversity of bacterial soil communities.

On the Negative Bias of the Gini Coefficient due to Grouping [PDF]

Journal of Classification, 2018
The Gini coefficient is a measure of statistical dispersion that is commonly used as a measure of inequality of income, wealth or opportunity. Empirical research has shown that the coefficient may have a nonnegligible downward bias when data are grouped. It is unknown under which grouping conditions the downward bias occurs.

Early prediction of multiple organ failure for sepsis patients based on machine learning algorithms

Journal of Intelligent Medicine, EarlyView.
Abstract In recent years, there has been a notable rise in sepsis incidence leading to more multiple organ failure and higher mortality. The lack of effective treatments for sepsis highlights the importance of early prediction in preventing multiple organ failure. This study aimed to develop a model for the early prediction of multiple organ failure in

Measuring and explaining economic inequality: An extension of the Gini coefficient. [PDF]

This paper proposes a new class of inequality indices based on the Gini’s coefficient. The properties of the indices are studied and in particular they are found to be regular, relative and satisfy the Pigou-Dalton transfer principle.

Linking Environmental Health and Civic Health: An Analysis of Air Pollution and Charitable Giving

Nonprofit Management and Leadership, EarlyView.
ABSTRACT This study examines the effect of air pollution on charitable giving. We suggest that the burdens associated with poor air quality are associated with a dampening of civic and philanthropic engagement. Analyzing 12 years of county‐level data from the United States with fixed‐effects OLS and instrumental variables regressions, we identify a ...

Systemic bio‐inequity links poverty to biodiversity and induces a conservation paradox

People and Nature, EarlyView.
Abstract Biodiversity is declining globally while inequity is growing, and poverty rates are not improving. Global sustainable development and conservation initiatives aim to address biodiversity loss and poverty simultaneously. Through text analysis of global biodiversity policies, we identified a consistent narrative that countries with high ...
