Aid Effectiveness on Accumulation: A Meta Study
对43篇研究发展援助对积累影响的论文进行元分析，发现援助中约25%转化为投资，其余75%被储蓄下降抵消，但结果差异大，积累是否增加存疑。
SUMMARY The AEL (aid effectiveness literature) studies the macroeconomic effects of development aid using cross‐country or panel data econometrics. It contains 97 papers of which 43 study whether development aid leads to increasing accumulation. The aggregate results of the 43 studies are that aid increases investment with about 25% of the aid, while most of the remaining 75% of the effect is crowded out by a fall in savings. However, these aggregate results are so variable that it is dubious if accumulation rises.
