This study assesses the impact of foreign direct investment (FDI) inflows on economic growth and domestic investment in a panel of Economic Co-operation and Development (OECD) countries during the period of 1990–2017 by utilizing the method of fixed-effects and system generalized method of moments (GMM). The findings show that FDI inflows are positively and significantly associated with the economic growth of the host economy. When considering the origin of FDI, we find that FDI from developed countries contributes to the growth rate in the receiving economy, while FDI from developing countries shows no significant effect. Importantly, FDI does not appear to crowd in or out domestic investment. Only FDI from developed countries is associated with crowding in of domestic investment.
