This book analyses the current understanding of how trade and aid work, and then examines a range of specific examples of how one has been used to support the other and how both developed countries and developing countries have found difficulty in reconciling the different approaches. Some of the worst apparent conflicts come from badly designed aid or trade policies, not from intrinsic inconsistency, and there is evidence that aid can be used to assist in trading more effectively than it has been in recent years, and that the resulting trade may be 'good for development'.
