This paper reviews the literature on corruption, anti-corruption efforts and aid, with a focus on: (i) tools for measuring corruption; (ii) the social science literature on the country-level causes of corruption and its relationship to poor governance; (iii) donor approaches to reducing corruption – both specific anti-corruption interventions and broader governance measures; and (iv) the debates and evidence on aid modalities and corruption.
