Sachs has popularized a strong finding: Distance from the equator
explains a great deal of the variation in income *levels* between
countries. The further from the equator, the richer countries are.
There are also some parallel findings for growth - controlling for other
factors, growth is slower in the tropics than in temperate zones.
Question: What would controlling for racial composition do to these
results? Clearly there is high collinearity between race and latitude,
though modern transportation is weakening the connection. If you do
both latitude and racial composition, what would happen? Does anyone
have hard evidence on this?
