There is significant academic evidence that growth in one country tends to have a positive impact on growth in neighboring countries. This paper contributes to this literature by assessing whether growth spillovers tend to vary significantly across world regions and by investigating the contribution of transport and communication infrastructure in promoting neighborhood effects. The paper is global, but the main interest is on Sub-Saharan Africa. The authors define neighborhoods both in geographic terms and by membership in the same regional trade association.
