The Gini Coefficient Reveals More [PDF]
We revisit the well-known decomposition of the Gini coefficient into betweengroups, within-groups and overlap terms in the context of two groups in which the incomes in one group may be scaled and that group’s population weight modified.

Not All Missing Data are Equal: Choosing the Right Imputation Method for Binary Datasets
Quality and Reliability Engineering International, EarlyView.ABSTRACT Missing binary predictors are common in reliability, quality control, and industrial decision systems, yet imputation methods are often chosen by convenience rather than evidence. We conduct a Monte Carlo study comparing mode substitution, sequential hot‐deck, missForest, MICE, and KNN with three neighbourhood sizes under MCAR, MAR, and MNAR ...

On the Decomposition of the Gini Coefficient: an Exact Approach, with an Illustration Using Cameroonian Data [PDF]
Decomposing inequality indices across household groups or income sources is useful in estimating the contribution of each component to total inequality.

Reconstructing Long‐Term Historical Hydrologic Alteration to Support Environmental Flows in Texas
River Research and Applications, EarlyView.ABSTRACT Understanding and quantifying hydrologic alteration is essential for effective watershed management and ecological conservation. This study developed a modeling framework to predict reference hydrology and assess and model hydrologic alteration across Texas using publicly available geospatial datasets.

Hedging with Stock Index Options: A Mean-Extended Gini Approach [PDF]
One of the more efficient methods to hedge portfolios of securities whose put options are not traded is to use stock index options. We use the mean-extended Gini (MEG) model to derive the optimal hedge ratios for stock index options.

Robust Inequality Comparisons [PDF]
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

On Calculation of the Extended Gini Coefficient. [PDF]
The conventional formula for estimating the extended Gini coefficient is a covariance formula provided by Lerman and Yitzhaki (1989). We suggest an alternative estimator obtained by approximating the Lorenz curve by a series of linear segments.

Fiscal Policy, Economic Growth and Income Inequality: A Case of Indian Economy [PDF]
Romanian Economic Journal, 2017 Through this study, we try to evaluate the effects that the direct and indirect taxation and the subsidies provided by the Government have on income inequality. We use Gini coefficient as a measure of inequality and use annual data for Indian economy for
