A response to the pressing need to address and clarify the substantial ambiguity within current literature, this edited volume aims to deepen readers’ understanding of the impact of foreign aid on development outcomes based on the latest findings in research over the past decade. Foreign aid has long been seen as one of two extremes: either beneficial or damaging, a blessing or a curse. Consequently, many readers perceive aid’s effectiveness based on the work of scholars who are assessing the impact of aid from one of two antithetical perspectives. This book takes a different approach, shedding light on recent research that can deepen our understanding of the complex relationship between aid and its aftereffects. Drawing from an extensive set of studies that have explored micro and macro impacts of foreign aid for recipient nations, chapter authors highlight more layered and nuanced findings, with a focus on donor characteristics, political motives, and an evaluation of aid projects and their effectiveness, including the differential impact based on type of aid. This volume is the first of its kind to unpack aid as a complex rather than a unitary concept and explore the wide areas of grey that have long enshrouded foreign aid.
