BK helps make the case for open borders in poor countries:
Interesting point by Jones: if high-IQ people produce positive externalities well above their market wages in poor countries, then citizenists in poor countries should be willing to offer larges subsidies for high-IQ immigration:
“If IQ has the sizeable positive externalities posited here, then there may be room for a Coasian bargain between countries with low current LV IQ and higher IQ individuals in other countries. One purely suggestive possibility: If the ratio of private to public benefits of higher IQ are even half as large as the 6:1 ratio suggested by Jones and Schneider (2010), a low LV IQ country could rationally offer a 100% subsidy for any wages a high IQ immigrant earns in excess of that nation’s median wage. In practical terms, a 10 year income tax holiday for permanent immigrants with engineering degrees could accomplish the same goal of encouraging high IQ immigration. “
Favoring engineers seems too much like “picking winners,” and I don’t think the research is really there to support anything so specific (don’t forget that the most obvious externality of engineers, that they invent things, is global in nature) but a simpler policy recommendation to derive from this argument would probably imply that poor countries should simply open their borders to immigrants from rich countries. Rich countries generally have higher average IQ, certainly higher levels of education, and probably other traits– work ethic, perhaps, or trustworthiness– that make their home countries productive. I don’t have great data on this– go, IMPALA!— but I’m pretty sure it wouldn’t be very easy for an immigrant from the US or Western Europe, with or without an engineering degree, to migrate to India or Malawi or China or Russia and just get a job, never mind a tax holiday. Why don’t poor countries offer free immigration to holders of US, EU, Japanese or South Korean passports? I suspect that it’s some combination of (a) elite protectionism– a corrupt business elite makes the rules and doesn’t want the competition from capable Westerners or East Asians– and (b) global norms– rich countries have migration restrictions and they’re either blindly imitating or else retaliating out of pride against countries that exclude them. But it would be interesting to investigate further.
Related thoughts: (1) Would it be easy for rich countries to negotiate away restrictions against their nationals working in poor countries, in return for a bit more openness to migrants from those countries, or perhaps other concessions, e.g., aid or trade? (2) Would a high-profile open-borders movement in the US and/or Western Europe, even while unsuccessful domestically, change the climate of ideas and persuade poor countries to open their borders to migration, to gain the “moral high ground?”
