Structural Change and Inequality in Africa

Abstract

This paper examines how inequality could be tackled through structural transformation using unit record data from the Demographic and Health Surveys (DHS) for Africa. Results suggest inequality between countries tends to be higher when the share of labour employed or value-added in the agriculture sector is higher, while no association is observed for industry and services sectors contributions to GDP or employment. Within-country inequality however tends to be strongly affected by structural change. A 1 standard deviation growth in the movement of labour from low- to high-productivity sectors could decrease overall inequality by 0.5% and inequality of opportunity by 1.1%. Results from other data sources strongly support these findings suggesting that positive structural transformation could lead to sustained reduction in inequality in Africa. Other factors correlated strongly with inequality reduction include human capital, which tend to have large and significant income or asset reducing effect in Africa, particularly at higher level of education, while the pace of urbanisation exacerbates it incidence.
