Does aid affect inequality?

We show that there was a negative correlation between pro-poor aid and inequality in the period before the mid-2000s. This article provides an explanation for this observed relationship. Using panel data on 34 countries for the period 1996-2014, we test the hypothesis that pro-poor aid has an inequality-reducing effect. To demonstrate that the negative correlation is not spurious, we use dynamic panel techniques with alternative specifications. We show that the share of pro-poor aid has a negative effect on inequality. In addition, we show that the interaction term between the poverty rate and the change in pro-poor aid has a significant effect. These empirical results are consistent with our theoretical predictions. The results imply that aid can reduce inequality by altering the allocation of aid, rather than by increasing the amount of aid.
