Budget Support Versus Project Aid: A Theoretical Appraisal
通过模型比较有条件预算支持与项目援助的效果，发现当援助方与受援方偏好一致且援助规模较小时，预算支持更优；若无法观察受援方类型，则需更高条件性来区分政府承诺度。
Should donors interested in the effectiveness of developmental programmes rely on conditional budget support or on project aid? To answer this question, we present a model in which only a subset of developmental expenditures can be subject to conditionality. We show that budget support is preferable to project aid when the preferences of donors and recipients are aligned, and when assistance is small relative to the recipients' own resources. Furthermore, when donors cannot observe the recipient's type, they may impose higher levels of conditionality to separate committed governments from uncommitted ones.
