This research review offers an insight to some of the most important questions economists and policymakers have been grappling over. A substantial amount of research has been carried out using cross-country regression models, resulting in a better and improved understanding of the linkage between economic growth and poverty reduction. The literature on cross-country regressions, however, has led to conflicting conclusions. Reconciling diverging messages makes it difficult to accurately inform policy-making. Based on a selection of influential papers, this volume provides a critical review of the literature. Scholars who envision a world free of extreme poverty will find this analysis particularly valuable.
