“…While some studies concluded that aid does not affect or even negatively affects economic growth (Boone, 1994;Easterly, 2003;Easterly, 2008;Gyimah-Brempong et al, 2012;Moyo, 2008), others showed a positive relationship between aid and growth (Arndt et al, 2015;Clemensn et al, 2004;Galiani et al, 2014;Lof et al, 2015) with a decreasing marginal return of aid (Collier & Dollar, 2001;Dalgaard et al, 2004;Durbarry et al, 1998;Hansen & Tarp, 2001). Others else concluded that aid is only effective at supporting positive economic growth when recipient countries adopt good economic policies (Burnside & Dollar, 2000;Burnside & Dollar, 2004;Chauvet & Guillaumont, 2003).…”
