FDI doesn't help with economic development?

The Winter issue of International Organization has an article by Stephen Kosack and Jennifer Tobin entitled Funding Self-Sustaining Development: the Role of Aid, FDI and Government in Economic Success.(Not sure if the link will work) The Abstract says:

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.

Its a long article with a fair amount of math so i don't understand much of it. Plus there no pretty pictures so i doubt i actually understand any of it. But if there thesis is correct then it brings about some questions and throws a few develomist theories in the pit of wrong theories. It also shows that aid is needed a lot more then its currently available.

I'm somewhsurprisedsed on how little coverage there is on this article. No blogs have covered this article even though it might have a resounding effect in the development community(Probably not, but i'm trying to hype this so i can get credit for being the first one to highlight this very improtant article that might change the very nature of human knowledge). I will cover more tomorrow with another post where i actually read the article with both eyes rather then my current state of having one eye shut. Maybe I'm a pirate develomist. aarrr there be aid!
