Inequality, Poverty, and the Intra-Household Allocation of Consumption in Senegal
利用塞内加尔家庭内部消费数据，量化了忽视家庭内不平等对总体不平等和贫困的估计偏差，发现家庭内不平等解释了14%的不平等，且家庭结构是关键因素。
Abstract Intra-household inequalities have long been a source of concern for policy design, but there is very little evidence about their effects. The current practice of ignoring inequality within households could lead to an underestimation of both overall inequality and poverty levels, as well as to the misclassification of some individuals with regard to their poverty status. Using a novel survey for Senegal in which consumption data were collected at a disaggregated level, this paper quantifies these various effects. In total, two opposing effects, one on mean and one on inequality, compensate each other in terms of the overall poverty rate, but individual poverty statuses are affected. Intra-household consumption inequalities account for 14 percent of inequality in Senegal. This study has also uncovered the fact that household structure and organization are key correlates of intra-household inequality and individual risk of poverty.
