"This paper explores the current debates on aid and growth. It begins by providing an overview of three different views of the aid growth relationship: there is (1) no relationship (or a negative one), (2) a positive relationship, usually with diminishing returns; or (3) a conditional relationship in which aid works in some circumstances but not in others ... It then explores in depth one of the newer contributions to the debate - evidence that different types of aid have different relationships to growth." (Quoted from paper)
