Are the direct and indirect growth effects of remittances significant?

Development economists believe that migrant workers' remittances are an important source of funds for long-run growth. Therefore, recent studies have investigated the growth effects of remittances but reached different conclusions. In these studies, the rate of growth of output is simply regressed on both remittances and the channels through which remittances affect growth. Thus, no distinction has been made between the indirect and direct growth effects of remittances. Such regressions may give unreliable estimates because the channels may also capture some growth effects of remittances, making the growth effects of remittances insignificant. In this study, we make a distinction between the indirect and direct growth effects of remittances. Our model is estimated with panel data of 40 high remittance recipient countries with the system generalized method of moment. We found that remittances have no direct growth effects but they have small indirect growth effects
