Via Econlog, Paul Romer says:
"I would distinguish questions about development from questions about growth. Development is the set of questions around why some people, some nations have very low standards of living compared with others...
What's wrong in many parts of the world is they don't have these institutions, and of the two [kinds], it's much more the market institutions which are fundamentally lacking, because if you think about it, a poor country in sub-Saharan Africa could get enormous benefits from just making use of what's already known in the rest of the world without necessarily contributing to that body of knowledge itself. If they could just put in place institutions that let them essentially freeload, take advantage of what's already known, they could do much better."
Most of the difference between the third and first world is in agricultural technology. So what Paul is saying is why are the Africans and Amazonian Brazilians so stupid that they don't just adopt the latest high-yielding, rust resistant variety of Winter Wheat from Iowa? It must be their institutions, Paul sayeth. Well, of course, their soils are completely unsuitable for wheat developed for Iowa. African pests are completely unlike European or North American pests. What Africans need is a higher yielding variety of Cassava, developed for Africa -- except they can't exactly take that technology from rich countries now, can they?
