Aid, Volatility and Growth Again. When Aid Volatility Matters and When it Does Not

Abstract : In previous papers we have argued that aid is likely to mitigate the negative effects of external shocks on economic growth (i.e. that aid is more effective in countries which are more vulnerable to external shocks). Recently an important debate has emerged about the possible negative effects of aid volatility itself. However, the cushioning effect of aid may involve some volatility in aid flows, which then is not necessarily negative for growth. In this paper we examine to what extent the time profile of aid disbursements may contribute to an increase or a decrease of aid effectiveness. We first show that aid, even if volatile, is not clearly as pro-cyclical as often argued, and, even if pro-cyclical, is not necessarily destabilizing. We measure aid volatility by several methods and assess pro-cyclicality of aid with respect to exports, thus departing from previous literature, which usually assess pro-cyclicality of aid with respect to national income or fiscal receipts. The stabilizing/destabilizing nature of aid is measured by the difference in the volatility of exports and the volatility of the aid plus exports flows. Then, in order to take into account the diversity of shocks to which aid can respond, we consider the effect of aid on income volatility and again find that aid is making growth more stable, while its volatility reduces this effect. We finally evidence through growth regressions that the higher effectiveness of aid in vulnerable countries is to a large extent due to its stabilizing effect.
