Revisiting cross-country poverty convergence in the developing world with a special focus on Sub-Saharan Africa

The literature on poverty convergence is sparse and much of the empirical evidence relies on Ravallion (2012) who found a lack of poverty convergence across some ninety Less Developed Countries (LDCs) during 1980-2007. This paper revisits cross-country poverty convergence using data from the same sources but an extended period of 1980-2014. We find that while poverty convergence remains absent across LDCs, it is present in Sub-Saharan Africa (SSA) during the extended period. Initial poverty canceling the effectiveness of growth in reducing poverty explains the lack of poverty convergence across LDCs; while a strong growth effect dominating the adverse effect of initial poverty on growth effectiveness explains the strong poverty convergence found in SSA. A direct adverse link between initial poverty and subsequent growth - which Ravallion (2012) recognized as the main impediment to poverty convergence during 1980-2007 - is not found in this study. 2019 Elsevier Ltd.
