The paper examines empirically the proposition that aid to poor countries is detrimental for external competitiveness, giving rise to Dutch disease type effects. At the aggregate level, aid is found to have a positive effect on growth. A sectoral decomposition shows that the effect is (i) significant and positive in the tradables and the nontradables sectors, and (ii) equally strong in both sectors. The paper thus provides no empirical support for the hypothesis that aid reduces external competitiveness in developing countries. A possible reason for this finding is the existence of large idle labour capacity that prevents the real exchange rate from appreciating.
