The driving importance of foreign aid shows no sign of abating. Widespread and acute poverty still ravages many countries of the world and the understanding of how aid affects the economies of the recipient countries is still far from perfect. This work attempts to bring together many aspects of the literature on the subject of aid. It presents a broad survey and also provides a more specific treatment of elements of aid that have yet to be explored. It can serve as both a reference work as well as a research monograph and should be of use to students, as well as to researchers and policy makers.
