This article challenges a long-held development-policy assumption that
aid and foreign-direct investment (FDI) serve as substitutes or
complements in accelerating the development of the world's poorer
countries. We show both theoretically and empirically that aid and FDI
affect development differently. Aid contributes powerfully to both
economic growth and human development, and the higher the level of human
capital in a country, the more aid contributes. By contrast, FDI, at best,
has no effect on economic growth and actually slows the rate of human
development in less-developed countries. We find no evidence that the
degree of democratic responsiveness in government conditions the
effectiveness of either aid or FDI, although we do find that democracy
independently increases human development in all but the most developed
countries. Our results demonstrate that FDI and aid are not, and cannot
be, substitutes in the development of the world's poorer countries.
Nor even can they be thought of as complements—certainly not at mid
to low levels of development. In the end, poor countries need democracy
and aid, not FDI.We are extremely grateful
to Susan Rose-Ackerman, Gustav Ranis, Frances Rosenbluth, Kenneth Scheve,
and participants at the Leitner Political Economy Seminar at Yale
University in December 2003 for very helpful comments. We also received
valuable suggestions from two anonymous reviewers. Stephen Kosack would
