The aim of this study is to check if  remittances and aid  are  complements or substitutes  in the growth process in West African Economic Monetary Union (WAEMU). Clearly it aims to check if  remittances and  aid complete  each other to increase economic growth.  By using  data on the sample of  WAEMU Countries with panel Dynamic Ordinary Least Squares (DOLS) on the period 1980-2015, the results show that remittances  and aid have  a  substitution  link. The  results also highlight that  remittances  have  a  negative effect on growth, but  aid has no  significant  effect  on growth.
