This paper investigates the effect of foreign direct investment (FDI) on economic growth conditional on the institutional quality of host countries. We first develop several theoretical arguments to show that institutional heterogeneity may be an explanation for the mixed results of previous empirical studies. Second, using a panel smooth regression model on a large sample of developing countries, we show that FDI has a positive effect on growth only beyond a certain threshold of institutional quality. To benefit from FDI‐led growth, institutional reforms should thus precede FDI attraction policies. Additionally, some reforms seem to promote faster marginal effects of FDI, while institutional complementarities may lead to an incremental effect on growth.

This paper investigates the effect of FDI on economic growth conditional on the institutional quality of host countries. We consider institutional heterogeneity to be an explanation for the mixed results of previous empirical studies and we develop several arguments to show that institutional quality modulates the intensity of FDI impact on growth. Using a comprehensive data set for institutional quality, we test this hypothesis on a sample of 94 developing countries over the period . The use of Panel Smooth Transition Regression (PSTR) allows us to identify both the heterogeneity and the threshold of institutional quality that influence the FDI growth effect. These results have significant implications for policy sequencing in developing countries. In order to benefit from FDI-led growth, the improvement of the institutional framework should precede FDI attraction policies. While some features of institutional quality have an immediate effect on fostering FDI-led growth, others need a consistent accumulation of efforts, therefore challenging the effectiveness of institutional reforms in developing countries.
