This volume provides a set of six case studies from West Africa. These assess the benefits of growth (or the costs of a lack of growth) in terms of poverty reduction in those countries. The first part of this book describes the experience of two countries (Ghana and Senegal) that achieved high levels of growth in the 1990s, and that also experienced important reductions in poverty, even though growth was not strictly pro-poor. The second part describes the experience of two other countries (Burkina Faso and Cape Verde) that also achieved high levels of growth in the 1990s, but where there was an initialperception that growth did not lead to much poverty reduction. The more detailed analysis of poverty presented here suggests however that these two countries did witness a sharp reduction in their population share in poverty, as would have been expected given their growth record. Finally, in the third part, the authors argue that a lack of growth in the 1990s in Guinea-Bissau and Nigeria has been a key reason for their persistently high levels of poverty.Overall, the case studies in this Working Paper make a strong case for the positive impact of growth on poverty reduction in West Africa. However, they also point to theneed to pay close attention to changes in inequality, because such changes have limited the gains from growth for the poor in several of the countries considered here.
