Generalized Gini and Concentration coefficients (with factor decomposition) in Stata
نویسنده
چکیده
This document describes sgini, a lightweight command for calculations of generalized Gini (a.k.a. S-Gini) and Concentration coefficients from unit-record data (not grouped data) in Stata. sgini computes relative (scale invariant) Gini indices of inequality by default but can be requested to produce absolute (translation invariant) indices or aggregate welfare S-Gini indices. The command can also optionally report decomposition of these indices by factor components (income sources). As this document shows, while the scope of the command itself is seemingly relatively narrow, sgini can serve as a flexible building block in a wide array of economic applications. The command is available online for installation in net-aware Stata. At the command prompt, type

The binomial Gini inequality indices and the binomial decomposition of welfare functions
In the context of Social Welfare and Choquet integration, we briefly review, on the one hand, the generalized Gini welfare functions and inequality indices for populations of n ≥ 2 individuals, and on the other hand, the Möbius representation framework for Choquet integration, particularly in the case of k-additive symmetric capacities. We recall the binomial decomposition of OWA functions due ...
متن کاملGeneralized Multilevel Structural Equation Modeling
A unifying framework for generalized multilevel structural equation modeling is introduced. The models in the framework, called generalized linear latent and mixed models (GLLAMM), combine features of generalized linear mixed models (GLMM) and structural equation models (SEM) and consist of a response model and a structural model for the latent variables. The response model generalizes GLMMs to...
متن کاملThe Inequity of Expenditure Ratios on Health and Food among Different Deciles of Iranian Households
Background and purpose: Utilization of health care services and food influence the health status. The food and health care expenditure ratios determine the importance level of them in household's consumption expenditures. We aimed to investigate the Iranian rural and urban food and health expenditure ratios inequality during 1998 to 2012. Materials and Methods: This is a descriptive longitudina...
متن کاملDynamics and Sources of Expenditure Inequality in Bhutan: Theil and Blinder Oaxaca Decomposition Analysis
The distinct feature of Bhutan is its special attention to peace, prosperity and happiness for its people. This research focuses on the expenditure inequality for 2007 and 2012 using various measurements including Gini Coefficients, Theil Indices and Blinder-Oaxaca decomposition. The results show that “between” rather than “within” inequality is the major factor contributing to the overall ineq...
متن کاملA Family of Correlation Coefficients Based on Extended Gini
The extended Gini is a family of measures of variability which is mainly used in the areas of finance and income distribution. Each index in the family is defined by specifying one parameter. The higher the parameter, the more weight is attached to the lower portion of the cumulative distribution. In this paper we list and investigate the properties of the equivalents of the correlation coeffic...
