A New Class of Lorenz Curves of Urban Household Expenditures in Iran
Ali Khosravi Tanak, Gholamreza Mohtashami Borzadaran *
Abstract:   (1682 Views)
Lorenz curve is one of the most important graphical tools for describing the inequality in income, wealth and other welfare indices in a society. Therefore, the estimation of Lorenz curve has always been of interest to researchers in the social sciences and economics. ‎ Hitherto, many models have been proposed for estimating the Lorentz curve. Khosravi Tanak (1396) introduced two new classes of Lorentz curve using the maximum entropy share function and based on a constraint on generalized Gini index. He showed that one of them modeled the considered data, which relates to the three Asian countries, better than alternatives. In this paper, we investigate the fitting of these models to expenditure data of urban households in Iran in the years 1388, 1390 and 1392 SH.
Keywords: Lorenz curve, Share function‎, ‎Gini index, income distribution, expenditure distribution.
