“…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). Finally, we add to the literature on regional and ethnic favoritism in the distribution of resources (Alesina, Michalopoulos, and Papaioannou, 2016;Alesina, Baqir, and Easterly, 1999;Francois, Rainer, and Trebbi, 2015), and highlight the potential multiplier effects of regional favoritism in domestic redistribution of health resources post an epidemic.…”
