This book provides a comprehensive search for the basic political drivers of international development cooperation, based on the policy and performance of the OECD countries from the early 1960s to the present. The author focuses on the stated and implemented policies of the four so-called frontrunners and the Western hegemon, scrutinizing the changing trends in the justifications, objectives and guidelines set for the policy and their evolving performance vis-a-vis the international ODA target. Through extensive research, the work examines predominant world-views, societal value systems and foreign policy traditions, in order to find the policy drivers that vary nation to nation and how development assistance has evolved globally.
