Few issues in the development process raise as much heat as the role of the international private sector in the form of transnational corporations (TNCs) and foreign direct investment (FDI). This article reviews the most recent research on the impact of FDI on economic growth and poverty reduction in developing countries. A brief history of FDI is given. This is followed by discussion of the conceptual transmission mechanisms linking FDI, growth, and poverty. The available empirical evidence is then discussed.
