What Is the Aggregate Economic Rate of Return to Foreign Aid?
通过模拟方法验证2008年以来实证研究的连贯性，并计算外国援助回报率的合理范围，发现其与公共投资回报率相当，且未对生产率产生显著负面影响。
In recent years, academic studies have been converging towards the view that foreign aid promotes aggregate economic growth. We employ a simulation approach to: (i) validate the coherence of empirical aid-growth studies published since 2008; and (ii) calculate plausible ranges for the rate of return to aid. Our results highlight the long run nature of aid-financed investments and the importance of channels other than accumulation of physical capital. We find the return to aid lies in ranges commonly accepted for public investments and there is little to justify the view that aid has had a significant pernicious effect on productivity.
