Aid and Growth: What Does the Cross-Country Evidence Really Show?
在纠正了增长较差可能吸引更多援助的偏差后，发现跨国数据中援助流入与经济增长之间几乎没有稳健的正向或负向关系，且援助效果不因政策或地理环境而异。
We examine the effects of aid on growth in cross-sectional and panel data-after correcting for the possible bias that poorer (or stronger) growth may draw aid contributions to recipient countries. Even after this correction, we find little robust evidence of a positive (or negative) relationship between aid inflows into a country and its economic growth. We also find no evidence that aid works better in better policy or geographical environments, or that certain forms of aid work better than others. Our findings suggest that for aid to be effective in the future, the aid apparatus will have to be rethought.
