The Fungibility of Health Aid Reconsidered
重新评估一项有影响力的研究，该研究认为健康援助长期完全可替代；考虑预算外援助后，发现可替代程度更不确定，甚至可能仅有限可替代。
This article draws further attention to the importance of taking into account off-budget aid when estimating the degree of foreign aid fungibility. It does so by re-evaluating the results of a recent, influential paper which concluded that health aid is fully fungible in the long run. Allowing for the presence of off-budget aid indicates that the degree of fungibility of health aid is much more uncertain than at first blush appears. Under plausible assumptions about the role of off-budget aid, the conclusion of full fungibility is overturned and at most only a limited degree of fungibility is found.
