“…First, aid can influence tax revenue: A negative relationship plausible when aid (especially grants) is viewed by recipient countries as a politically cheaper source of revenue crowds out domestic taxation; and a positive relationship plausible when aid strengthens revenue administration or supports tax policy reform through technical assistance, projects and budget support. Recent cross‐country and country‐specific research on the impact of aid on taxation provides insights to show how donors can support increasing tax revenue rather than allowing aid to substitute for domestic effort (Bwire et al, 2017; Clist, 2016; Clist & Morrissey, 2011; Mascagni & Timmis, 2017; Tagem, 2017). This is through behavioural effects, gauged by the political costs of aid and tax that offset each other (Morrissey, 2015b; Morrissey & Torrance, 2015; Tagem, 2017); the positive impact of transfers of ideas and practices through technical assistance and projects for capacity building (Goldsmith, 2001; Tagem, 2017); and the stability of donor–recipient relations that manifests itself in the stability of foreign aid flows (Tagem, 2017).…”
