Construction of a Consumption Aggregate Based on Information from POF 2008‐2009 and Its Use in the Measurement of Welfare, Poverty, Inequality and Vulnerability of Families
利用巴西家庭支出调查数据构建家庭消费总量，并据此分析福利、贫困、不平等和脆弱性，考虑了支出选择、极端值、食品消费归因、耐用品使用成本和空间价格指数等因素。
Given the complexity of family and individual welfare, this study aims to explain the construction of a family consumption aggregate, using data from Brazilian Family Expenditure Survey (2008–2009), and also to measure and analyze welfare, poverty, inequality and vulnerability. Following the literature, some aspects were considered: the selection of expenditures, the analysis of extreme values, the imputation of food consumption, the user cost of durable goods and a spatial price deflator. After the definition of the family consumption aggregate, we analyzed the Generalized Lorenz Curves, social welfare functions and inequality measures. Then we presented the sensitivity of the identification exercise to different poverty lines and analyzed the severity of poverty. Finally, based on Chaudhuri et al . (2002) and Elbers et al . (2002), the vulnerability to poverty was studied taking account of area (clusters) effects. In this last exercise, the poverty line was based on half the minimum wage in 2008.
