Identifying differences and similarities between donors regarding the long-term allocation of official development assistance

ABSTRACT Advanced countries have pledged to mobilize additional financial resources to developing countries, including funding from multiple sources other than official development assistance (ODA), known as foreign aid. However, the effect of the novel coronavirus pandemic has raised doubts about the feasibility of such a pledge, highlighting, once again, the possible role of ODA and the importance of explaining its allocation, which could be of vital relevance for understanding its effectiveness. This study analyzes a vast number of bilateral and multilateral donors by applying a novel methodology in the context of aid allocation – principal-component factor analysis – covering the period 1990–2015. The results revealed four distinct clusters of donors: (i) the proportionally largest Western European donors, characterized by a significant number of beneficiaries, especially low-income countries; (ii) donors that are predominantly driven by structural links with recipients, especially links derived from colonial connections; (iii) a group of mainly Eastern European donors who are engaged with lower-income countries in Eastern Europe and Western Asia; and (iv) a group of Asian and Oceanian donors that select their partners mainly based on the geographical proximity criterion.
