SUMMARY
Sub-Saharan Africa (SSA) countries have benefited for more than fifty years from international aid in the form of loans and/or donations. Nevertheless, they seem not to benefit from these massive financial resources (ODA) they receive because their economic and social situation is not very good. This study aims to assess the impact of ODA on economic growth in SSA and to see if its effect on growth is conditioned by the quality of the economic policy. The estimates are conducted on a dynamic panel of twenty-three SSA countries running from 1985 to 2014. With macroeconomic data from the World Bank's CD-ROM (World Development Indicators, 2015), the Generalized Method of Moment (GMM) system from Blundel and Bond (1998) was used. The results show that the impact of ODA on growth is not significant. Subsequently, when squared aid (ODA2) is included in the estimate, ODA becomes significant, meaning that a substantial amount of assistance is required to be effective in raising the economic growth rate of the SSA countries. In addition, the effectiveness of ODA is conditioned by the quality of the economic policy. This seems to be bad in SSA, hence the negative impact of the aid on economic growth.
