This article assesses the heterogeneous effects of immigration on economic growth depending on both the origin and the destination countries. Following the development of a growth model augmented by human capital of immigrants, we estimate it in a dynamic panel setup using the system-GMM estimator. We find that the growth-enhancing effect of immigration is significantly larger when immigration flows from developed to developing economies than when it does to those that include both developed and developing economies. We interpret these results as evidence of immigrants from developed countries bringing with them their advanced knowledge into the developing countries.
