Numerous investigations have been carried out to find the effect of foreign direct investment (FDI) on economic growth. Several studies have been carried out in both developed and developing countries (Akinlo, 2004). The purpose of this study is to investigate the empirical relationship between FDI and per capita GDP growth of the developing countries of West Africa (Senegal, Mali and The Gambia) from 2005 to 2023. A static fixed panel model was used to estimate the impact of FDI inflows. Given the potential endogeneity of FDI with respect to economic growth, the study also employed a two-stage least square (2SLS) estimation method to ensure robust causal inference. The model consists of FDI, percentage working population, secondary school enrollment, literacy rate and trade openness. The results confirmed a statistically significant and positive effect of FDI on per capita GDP growth. The study concludes that FDI inflows can contribute to the economic growth in Sengal, Mali and The Gambia.
