Aid unpredictability and absorptive capacity: analyzing disbursement delays in Africa

This paper examines the extent to which aid disbursement delays could be used as an indicator of the aid unpredictability and absorptive capacity in recipient countries. Since many recipient countries are dependent on aid, disbursement delays might matter for its effectiveness. The emphasis is put on the so-called pipeline approach, according to which, in the short run, disbursement constraints may lead to huge delays and weak rates of aid disbursement relative to commitments. After the literature review on disbursement delays, we use the framework of programmable aid to run some econometric estimations through a dynamic model, an ARDL, for a panel of 48 African countries during the period of 1975-2008. We find disbursement constraints mainly at the short-run level, while the main donor's specific factors seem to be the selectivity and the degree of aid fragmentation. Disbursement rates and rhythms are also influenced by the economic performance and governance quality of the recipient countries and the share of grants in aid modalities. Bilateral donors are found to under-perform in comparison with multilateral donors in terms of the rhythm of aid disbursement.
