Seminar | The nexus between consumption inequality and multidimensional poverty in Ghana

This study documents changes in consumption inequality in Ghana from 2005 to 2017. It focused on the causal link from consumption inequality to household multidimensional poverty.

The research was done by members of ACEIR’s Kenya node: Dr Raymond E. Kofinti, Prof. Damiano K. Manda, Dr Martine Olechea, and Prof. Germano Mwabu.

The team used three rounds of the Ghana Living Standards Survey, augmented with district-level administrative data. Consumption inequality was measured by using the Gini coefficient at the district level, and multidimensional poverty was measured using the Oxford Poverty and Human Development Initiative's index. The control function approach was employed to measure the effect of consumption inequality on multi-dimensional poverty. 

The researchers found an upward trend in district consumption inequality at the national level between 2005 and 2017, which is consistent with the inequality trends for the Savannah and Forest ecological zones but not with the trends for the Coastal zone.

The main result from the regression analysis was that inequality increased multidimensional poverty, a finding that was robust to alternative measures of inequality and poverty. They also found that the association between poverty and inequality was more pronounced in rural areas and amongst male-headed households.

Neighbourhood unrest was an important channel through which inequality operated to increase multidimensional poverty. The authors put forward policies that the government can use to reduce both poverty and inequality in Ghana.
