Harmony or Cacophony? A Disaggregated Analysis of Aid Fragmentation

Aid effectiveness is widely understood to suffer when multiple donors operate in the same space, but recent studies indicate benefits of fragmentation. We posit that these mixed findings may reflect differences across aid sectors – and also show how the level of implementation can condition the interpretation of results. Cross-national time-series analysis of 152 countries implies aid fragmentation can promote child survival and improve governance. However, analysis of subnational variation in Sierra Leone and Nigeria suggests the presence of more donors is associated with worse health outcomes, but better governance outcomes. Having more donors in a locality may thus be beneficial when they are working to improve the systems through which policies are implemented, but harmful if they target policy outcomes directly. A survey of Nigerian civil servants suggests potential mechanisms: fragmentation in health aid may lead to internal "brain drain" and pressure to alter projects, whereas diversity in governance aid might promote meritocratic behavior.
