Putterman's Wold Migration Matrix
"When Putterman and Weil used the matrix to investigate the effects of the post-1500 population movements on income differences today, the results were “almost breathtaking.” The power of regional origins is illustrated by the fact that in a 125-country regression, 44 percent of the variance in current per capita GDP is accounted for by entering only the share of the population’s ancestors that lived in Europe in 1500....

Putterman and Weil reflect on the implications of this work in a column on Voxeu.org, a Web site featuring research-based policy analysis and commentary from leading economists:

Second, the influence of population origins suggests that there is something that human families and communities transmit from generation to generation — perhaps a form of economic culture, a set of attitudes or beliefs, or informally transmitted capabilities — that is of at least similar importance to economic success as are more widely recognized factors like quantities of physical capital and even human capital in the narrower sense of formal schooling. If we understand which culturally transmitted factors are important and what contributes to their emergence and propagation, we might be able to design policy interventions that could help less successful groups and countries to close their developmental gaps.”

We could just rerun the analysis, substituting National IQ for GDP.

Obviously, the thing that families transmit, the very defining characteristics of a family, is genes. Are they intentionally being thick-headed or?

This is pretty cool too, as it focuses on the migration of intellectuals in Europe:
