Abstract: | Many African democracies experience highly variable aid flows. This article examines the influence of aid changes on presidential incumbent advantage in Africa. Aid changes influence the odds of incumbents winning reelection, with aid increases helping incumbents, but this effect is only present when the aid change occurs in the year before an election. Aid changes in earlier or later time periods have no influence. Case studies of elections in Ghana and Malawi reveal causal mechanisms linking aid changes to incumbent advantage and support the finding that aid changes have a limited window of influence. |
