We construct an open economy disequilibrium model to assess the welfare effects of aid in different macroeconomic regimes. Aid is shown to have different effects in different unemployment regimes because it increases the social costs of wage-price rigidities in the classical regime but decreases them in the Keynesian unemployment regime. A link is made with the two-gap model, but we highlight the role of real exchange rate misalignment (failure to clear the NTgoods market). We finally give simple formulas for the welfare effects of aid in different regimes that should help in empirical application.
