Introducing and Estimating Two New Income Distribution Inequality Indices for Iran; S-Gini Coefficient and Atkinson-Gini Index

Reducing income inequality is one of the important goals of every countryʹs economic decision makers. But proper policy making requires exact and correct information about the severity of this inequality. Since usual income inequality indices have some kind of deficiencies, two new indices namely, S-Gini coefficient and Atkinson-Gini indices are being introduced, their properties reviewed and then estimated based on raw household budget data for 1997-2007. Our findings indicate that household income inequality in rural areas is more severe than urban, while the reverse is true when it comes to the per capita (individual) basis. Furthermore, although the severity of income inequality has been reduced till 2003, but increased afterwards.
