“…Our work also contributes to the economics literature on the role of donor aid in development (Alesina and Dollar, 2000;Burnside and Dollar, 2000;Easterly, 2006;Nunn and Qian, 2014;Bräutigam and Knack, 2004). While a robust literature has found mixed results on the benefits of foreign aid for development (Burnside and Dollar, 2000;Moyo, 2009), a more recent literature has noted that health aid may have positive impacts on human capital outcomes particularly in asset constrained regions (Odokonyero et al, 2015;Kotsadam et al, 2018;Gyimah-Brempong, 2015;Miguel and Kremer, 2004;Bandiera et al, 2019;Ndikumana and Pickbourn, 2017). Our paper provides quantitative evidence of the barriers to targeting donor aid and adds to the evidence of partial crowd-out that may occur, in areas like routine vaccination, when donor aid increases in response to epidemics of infectious disease (Bloom, Canning et al, 2004;Deserrano, Nansamba, and Qian, 2020;Aldashev, Marini, and Verdier, 2019).…”
