Aid Effectiveness—Opening the Black Box
分析援助资金如何影响发展结果，指出因果链复杂且充满噪音，难以回答政策制定者关心的关键问题，并探讨了援助交付方式的新趋势。
This paper examines the causality chain linking aid flows to development outcomes. It argues that many of the questions policymakers and economists would like data to answer simply cannot be answered due to the complexity and noise along links in the chain, and the problem of attribution. It then examines what is known about aid effectiveness along different links in the causality chain. Finally, it turns to recent trends in the way aid is delivered and the new model that appears to be emerging.
