This paper examines whether domestic output growth helps attract capital inflows and, in turn, capital inflows help boost output growth in a set of 38 Sub-Saharan African countries. Using a two-step approach to address reverse causality and omitted variable issues, the paper finds that output growth in countries in Sub-Saharan Africa does not attract capital inflows. However, aid and foreign direct investment inflows enhance growth, while sovereign debt inflows do not. A 1 percent increase in the level of real aid inflows raises growth of real output per capita by 0.022 percentage point. For foreign direct investment inflows, the figure is 0.002 percentage point.
