Financing Public Investment Through Foreign Aid : Consequences for Economic Growth and Welfare

This paper develops a theoretical framework for understanding the mechanism through which foreign aid affects macroeconomic performance.

Structural characteristics of the recipient economy are important in determining the extent to which external assistance can aid growth and welfare
