Desigualdade de renda e sua decomposição no Brasil e nas regiões brasileiras

Abstract

in the context of the analysis about the domiciliary surveys’ income measurement in Brazil, this paper aims to investigate the role played by different spheres of that domiciliary income with respect the 2002 and 2011 period. We intend to spell out if income inequality was indeed reduced in the latest years. To accomplish that goal, the data for the analysis are issued from Pesquisa Nacional por Amostra de Domicílios (PNAD); also by means of income concentration index, which is divided into 5 features: labor income, pensions and public pensions, private pensions, rents, allowances, grants. In that regard, it covers that Brazilian income inequality jumped from 0.5826 (2002) to 0.5241 (2011). Among other things, from the results obtained is the important fact that by decreasing the parts the income inequality is reduced as a whole, regardless the composition effect is taken to be harmless. The labor income revealed to play an important role in reducing the Gini index by means of effect-concentration (55.83%), and other incomes, which were responsible for reducing 20.72%. The rents and pensions offi cers contributed 18.07% for reducing the Gini index (G). Furthermore, the effects with respect the other incomes have undoubted infl uence on the reduction of Brazilian income inequality, especially in the Northeast.
