The Income Lever and the Allocation of Aid
提出了衡量一国减少自身贫困的货币能力的概念和指标（收入杠杆），并展示如何用这些工具指导预算或援助分配，基于不同规范标准构建指数对国家减贫能力进行排序。
The article develops a concept and a measure of the monetary capacity of a country to reduce its own poverty and shows how these tools can be used to guide budget allocations or the allocation of aid. The authors call this concept the income lever. Making use of tax and distributive theory, the article shows how different redistributive criteria correspond to the different normative criteria of the income lever. It then constructs various income lever indexes based on these criteria and uses such indexes to rank countries according to their own capacity to reduce poverty.
