Building on the growing body of empirical literature on aid effectiveness–including two of my recent publications—Amanda Glassman and Denizhan Duran at the Center for Global Development just published an interesting working paper that achieves two things simultaneously: it provides an excellent overview of the dramatic increase of Development Assistance in Health (DAH) globally during the past decade while also, for the first time as far as I am aware, ranking the individual performance of national as well as multilateral donor agencies in DAH. Echoing some of the findings documented in a recent paper by Bill Easterly and Claudia Williamson published in World Development, their analysis uncovers wide variation in both allocative efficiency and DAH agencies’ effectiveness as reliable, transparent and supportive partners for institutional development in recipient countries. The UK’s DFID ranks highest overall, followed by the Dutch and Danish aid agencies. GFATM is the highest-ranked multilateral agency in the sample. Conversely, selected UN agencies (clustered) rank lowest among multilateral organizations. Major bilateral donors such as Japan, Belgium and France also find themselves at the bottom of Glassman’s and Duran’s results.
