Validating stereotypes since 2005.
I'm not sure where to put this item which may be of interest:63A regression relating differences in fertility rates to our distance measures reveals a very significant and largeeffect of genetic distance on fertility differences. These results are available upon request. page40 of Diffusion of Development Spolaore,...accessible on current postings of Isteve.com
Thanks. Interesting that it was done by economists. The correlation between genetic distance and income is similar to that of IQ and income, only stronger. This suggests that progress is dependent upon, in addition to IQ, other variations in human populations. I asked for results on the correlation of genetic distance and fertility to see how it compares to IQ and fertility.
I emailed Enrico Spolaore about the correlation and he responded thus:"We find a positive correlation between genetic distance and population growth, which we report in the paper - we have not calculated the correlation with fertility."
One point of interest in Diffusion of Development is that they mention the effect described by Solow, in which faster population growth makes progressively more difficult, an increment in per capita growth in production.They interpret genetic distance from the zero point of the industrial revolution as proxying for barriers to diffusion of technology.Also they reference sources of historical data for incomes per capita between countries going back centuries: e.g. Angus Maddison's.
