Paul CollierLast week, we solicited your questions for award-winning Oxford University economist Paul Collier, author of The Bottom Billion and the just-published Wars, Guns, and Votes: Democracy in Dangerous Places.
In his answers below, Collier talks about why the impact of colonialism on Africa is exaggerated, how African countries are “too big to be nations, yet too small to be states,” and his belief that the I.Q. of a country’s citizens is “not closely related to the performance of an economy.”
Readers came through with great questions, and there is much to learn and admire in Collier’s answers. Thanks to all involved. (Here, by the way, are our past Q&A’s; send suggestions for future Q&A’s here.)

To what extent can the root causes of the gap between Western and African economic output be traced to cultural differences such as the rule of law, individualism, capitalism, and representative democracy? To what extent is African poverty a result of European colonialism and to what extent was European colonialism possible because of African poverty? Chicken or egg? — Mark Tueting

I am doubtful of cultural explanations. In South Korea people used to shuffle along the sidewalks; now they rush. The value of time has increased. East Asia was diagnosed as being incapable of development because of Confucian ethics!
I think that the continuing impact of colonialism on Africa is exaggerated. Ethiopia virtually escaped it and hasn’t done much better than the others — same with Sierra Leone and Liberia. European colonialism was helped militarily by African poverty, but the poverty also kept Europeans away. Take the Italians for example: only 3,000 settlers in their colony of Eritrea, versus vastly more emigrants to America.

What activities/goods/services are cheap in the first world but expensive in Africa, and why? Please answer this question from both a consumer’s perspective and from a business owner’s perspective.
– William Cross

Anything that is imported because of tariffs and monopoly distribution channels. Many services are badly organized such as retail distribution. On the other hand, some e-services are very good value in Africa.

What impact will the current recession have on the poorest/bottom billion? What policy intervention by Western/poor-country governments would make a significant difference and is realistic to expect?
– Rachel Eden

Recession: very different transmission channels, remittances down hit ordinary households, and the drop in commodity prices hits government revenues. But it is not all doom and gloom; Africa will still grow, unlike the U.S. and the U.K.
Policy intervention: a really easy one would be to require our banks, plus the tax-haven banks, to be as transparent about corrupt money deposited in them as about money linked to terrorism.

What do you think of Dambisa Moyo‘s argument that foreign aid to Africa should be reduced because it engenders dependency and undermines entrepreneurship? — Frank

Dambisa was my student, and I am delighted that young Africans are no longer prepared to have their continent defined by victimhood. They recognize that Africans can shape their own future. However, I don’t agree with her that aid is useless. Especially with the drying up of private finance, now is the hour for public international money; it is needed. It is, however, often badly used.

As an American citizen, what actions can I take to improve conditions for the bottom billion? Is there federal legislation I can advocate for or a charity I can donate to? — Kathleen Lisson

Legislation: extend the Africa Growth and Opportunity Act. Charities: Kiva and lots of exciting social enterprise. WorldVision is pretty sensible in my experience.

Do you think a lot of the countries in Africa are too small or too big (too many different cultures, identities, and tribes) to ever be able to function properly? — Neil Mc

Neil, this is the punchline from my new book, Wars, Guns, and Votes: Too big to be nations, yet too small to be states. So sadly, yes, I agree.

What do you think of Richard Lynn‘s findings about race differences in intelligence and their relatedness to Africa’s continuing state of underdevelopment? In his work, Mr. Lynn compiled the results of numerous studies which appear to show fairly unambiguously that average I.Q.’s in sub-Saharan Africa are below 70. Studies furthermore show that this disadvantage is almost certainly inherited genetically. — Denis Bider

I don’t know this stuff and don’t want to. But I am just about prepared to believe that the average Chinese person is smarter than the average Englishman. Despite this, the average Englishman is more than 10 times richer than the average Chinese person — so intelligence is manifestly not closely related to the performance of an economy.

With the exception of some very mountainous countries (Switzerland, Bhutan, etc.), almost all successful countries have had some amount of coastal land. There are several land-locked African nations; do you think there is any hope that they can develop successfully without coastal access? If not, how could this problem be addressed? — Kevin MN

I think that this is a very severe problem. They should not have become countries, but they have, so we need something more helpful. E-services, plus much better transport links to the coast would help.

I’m always amazed that the IQ myth pops up so many times. Its been debunked over and over again, but I think it must be comforting to people. First of all, IQ tests suck. Most are poorly designed. Designed by white westerners for white westerners; A putter is to golf as a ___________ is to tennis. And even when test attempt to adapt, this ignores the crucial fact that factors other than inheritance affect IQ. In fact, poverty has an overwhelmingly negative impact on IQ. Poor nutrition, poor education, and poor living conditions result in people with poor IQ’s. Change those conditions, and the IQ’s will rise.
Does anyone else get the impression that Mr. Collier’s responses were the bare minimum he could muster. Several of the answers were shorter than the questions they responded to. I know that the Freakonomics bloggers aren’t responsible for Mr. Collier’s answers, but I hope that future interviewers respond a bit more seriously.
I think the IQ question is relevant. Collier’s answer seems like a flip response to an uncomfortable question – surely the gap between the average Englishman and Chinese person is not large enough to explain anything in either direction.
I don’t really buy the racial IQ difference theory, it seems much more likely that poor nutrition and education are to blame. But that doesn’t change the fact of low IQs! A serious analysis has to take this fact into account, since low IQ is a crippling handicap to a country’s development, especially when combined with brain drain.
“do you think there is any hope that they can develop successfully without coastal access?”
Chicago is more or less proof that inland regions can succeed economically. They need free trade and better transport links.
“Too big to be nations, yet too small to be states.”
Should this be the other way around, or am I missing something here?
Karl said” In fact, poverty has an overwhelmingly negative impact on IQ. Poor nutrition, poor education, and poor living conditions result in people with poor IQ’s. Change those conditions, and the IQ’s will rise.”
Society seems to judge poverty based on a group of people having less than another group of people.
For example in the US we hear 40 million people don’t have health insurance. Well, 200 years ago no one had health insurance. Some how we have arrived at a point in time where health insurance is some how a necessity according to some.
It used to be, you got sick, you died. So if today, a person gets sick and dies, is that person any worse off than he would have been 200 years ago? I say not.
But what we are doing to basicaly saying: there are these people who get sick and get healthcare that saves them, it is not fair that other people dont. It is pure envy. If health insurance is a human right, then you are telling me that 200 years ago no one had their human right? That certainly is not the way that the people living at the time thought of it.
Just becuase I do better, does not mean that someone else who does not do as well is some how suffering injustice.
His answers are too short. This does get me excited about any books he wrote.
I don’t know anything about Richard Lynn’s IQ testing, but it strikes me as extremely unlikely that the average sub-saharan african has an IQ that is three standard deviations below the american norm. That would mean that your average subsaharan african has a lower IQ than 99% of americans.
My experience with africans from africa is not large, not representative, and not specifically sub-saharan, but I haven’t run across any africans that belong in that bottom 1%. I would give 4 to 1 odds that the cited study has easily identifiable methodological problems.
