Spatial Decomposition of Poverty in Niger: Shapley Decomposition Approach

Abstract

This paper examines the prevalence of poverty in Niger, using the Shapley approach. In doing so, I use a cross-sectional data for 2011/2014. The measurement index for well-being is consumption (the aggregate of food and non-food expenditure). The choice of consumption is premised on the common knowledge that it is not easily influenced by the volatility of income to price shocks and changes, as it tends to smoothen over time. The results obtained from the Shapley decomposition approach support the prevalence of poverty in Niger, with the rural areas being the more affected group.
