“…Aid interventions, for the most part, are delivered in the form of projects that respond to specific needs such as construction or improvement of roads or healthcare facilities, provision of anti‐malaria mosquito nets, immunization campaigns, improved nutrition, and so on. Thus, the direct impact of aid may be more discernible at the sectoral level (Simpasa, Shimeles, & Salami, 2015), and targeted interventions may be more effective in reducing infant mortality (Boone, 1996; Mary & Gomez y Paloma, 2015). Nonetheless, cross‐country studies may be useful to understand the impact of per capita aid expenditure on health outcomes in poor countries, even though they may miss out on sectoral and project level information, which micro‐level studies are better equipped to deal with (Kotsadam, Østby, Rustad, Tollefsen, & Urdal, 2018; Findley, Powell, Strandow, & Tanner, 2011).…”
