Aid and Growth: What Meta-Analysis Reveals
重新审视了元分析文献中关于外援对经济增长影响的假设，发现援助对增长有显著正向效应，且该效应并非出版偏误所致，并解释了为何结果与其他研究不同。
Abstract Recent literature in the meta-analysis category where results from a range of studies are brought together throws doubt on the ability of foreign aid to foster economic growth and development. This article assesses what meta-analysis has to contribute to the literature on the effectiveness of foreign aid in terms of growth impact. We re-examine key hypotheses, and find that the effect of aid on growth is positive and statistically significant. This significant effect is genuine, and not an artefact of publication selection. We also show why our results differ from those published elsewhere.
