Dirty Work and the Domestic Politics of Aid

Abstract Historically the United States uses both bilateral aid and influence over multilateral development finance to further its geopolitical objectives. Past studies explain the choice between these two instruments based on either a divided government effect or whether the recipient government is a traditional US ally (the dirty work hypothesis). We advance a theory explaining the bilateral/multilateral choice in terms of the confluence of these factors and test its predictions using United Nations Security Council voting, US bilateral aid flows, and World Bank lending. Results confirm theoretical expectations: higher bilateral aid goes to allies who support the United States in the Security Council but only when the US government is not divided and higher World Bank lending goes to non-allies who support the United States in the Security Council but only when the US government is divided. This detailed understanding of the link between domestic politics and governance in international organizations has important implications as the international order moves beyond a US-dominated system.
