This paper assesses the impact of capital flight on growth in thirty-one sub-Saharan African countries. It first considers the “macro fundamentals ” hypothesis that capital flight would be lower in a country whose government adhered to “sound ” macroeconomic policies. Analytical considerations fail to support this hypothesis. Second, it develops a growth estimating equation derived from the Harrod-Domar framework. The growth estimations support the conclusion that capital flight had a major impact on growth over the last three decades, 1980–2010. The negative impact was greatest for the petroleum-exporting countries and those affected by internal conflict, but it was also substantial for the other countries, with a few exceptions.
