The paper examines the effectiveness of foreign aid in promoting economic growth. It challenges the common belief that aid has no significant impact on growth and that aid is only effective when accompanied by good policies. The authors argue that aid does have a positive effect on growth, even in countries with unfavorable policy environments. They review existing literature on the aid-savings, aid-investment, and aid-growth relationships, and find that a coherent and positive picture of the aid-growth link emerges. The paper discusses the macroeconomic impact of aid, the aid-savings relationship, and the aid-investment relationship. It also addresses the issue of endogeneity and non-linear effects in the aid-growth relationship. The authors conclude that aid has a positive impact on growth, and that this impact is more significant when combined with good policies. The paper also highlights the importance of using appropriate econometric methods and considering the non-linear effects of aid on growth. The authors argue that the aid-growth relationship is complex and that further research is needed to fully understand its implications.The paper examines the effectiveness of foreign aid in promoting economic growth.
