In this article we re-examine the relationship between remittances and economic growth placing special attention to the non-linearity of this relationship. Previous studies have ignored the non-linearity of the relationship between remittances and economic growth or have used a quadratic term to capture non-linearity. We show that the relationship between remittances and growth is neither linear nor quadratic and propose the use of a semiparametric model to avoid the risk of misspecification bias from imposing an arbitrary functional form. We find evidence of a positive relationship between remittances and growth in parametric estimations, however, such relationship disappears when non-linearity is taken into account using nonparametric techniques.
