In today’s episode of Politically Dicey But Important Topics Of Research …

The newspaper article summarising the research: http://www.guardian.co.uk/science/2010/jun/30/disease-rife-countries-low-iqs

People who live in countries where disease is rife may have lower IQs because they have to divert energy away from brain development to fight infections, scientists in the US claim.

The controversial idea might help explain why national IQ scores differ around the world, and are lower in some warmer countries where debilitating parasites such as malaria are widespread, they say.

Researchers behind the theory claim the impact of disease on IQ scores has been under-appreciated, and believe it ranks alongside education and wealth as a major factor that influences cognitive ability.

Abstract

In this study, we hypothesize that the worldwide distribution of cognitive ability is determined in part by variation in the intensity of infectious diseases. From an energetics standpoint, a developing human will have difficulty building a brain and fighting off infectious diseases at the same time, as both are very metabolically costly tasks. Using three measures of average national intelligence quotient (IQ), we found that the zero-order correlation between average IQ and parasite stress ranges from r = −0.76 to r = −0.82 (p < 0.0001). These correlations are robust worldwide, as well as within five of six world regions. Infectious disease remains the most powerful predictor of average national IQ when temperature, distance from Africa, gross domestic product per capita and several measures of education are controlled for. These findings suggest that the Flynn effect may be caused in part by the decrease in the intensity of infectious diseases as nations develop.

For reference, the Flynn effect:  http://en.wikipedia.org/wiki/Flynn_effect

The Flynn effect describes an increase in the average intelligence quotient (IQ) test scores over generations (IQ gains over time). Similar improvements have been reported for other cognitions such as semantic and episodic memory.[1]  The effect has been observed in most parts of the world at different rates.

The Flynn effect is named for James R. Flynn, who did much to document it and promote awareness of its implications. The term itself was coined by the authors of The Bell Curve.[2]

The effect’s increase has been continuous and approximately linear from the earliest years of testing to the present. There are numerous explanations to the Flynn effect and also some criticism. There is currently a discussion if the Flynn effect has ended in some developed nations since the mid 1990s.

Thinking about Human Rights (and UNICEF)

Before I begin:  UNICEF has a campaign in the UK at the moment to raise awareness of children being denied their rights around the world.  You can see the homepage for the campaign here.  You can donate here.

Here are some things to keep in mind when thinking about human rights:

  • A right is a particular form of liberty.  It is the freedom to do something.
  • An obligation or mandate is the opposite of a right.  A right involves a conscious choice; thus the phrase “to exercise one’s right.”  If there is no choice available, there is no right.
  • One person having a right often implies denying another right from a second person.  Suppose that you work for me.  If I have the right to fire you, you cannot have the right to a guaranteed job with me.  If you have the right to go on strike, I cannot have the right to fire you for going on strike.
  • Sometimes having a right does not impede the rights of others.  A right to make use of a non-rival good is the classic example.
  • Exercising a right is not necessarily in a person’s best interest.  I have the right to gamble all of my money at a casino, but it probably wouldn’t be wise to do so.
  • Every decision of consequence for everybody, everywhere, is subject to a constraint of some kind.  There are only 24 hours in a day, the resources at your disposal are finite and, eventually, you will die.
  • If a person, operating under a constraint, chooses to not do something, it does not imply that their right has been denied to them.

These last two points, while logical, create problems for many advocacy groups.  Consider the woman who, subject to constraints in her finances and the wages on offer for various jobs she can perform, chooses to become a prostitute.  Consider the subsistence-farming family that, subject to constraints in it’s finances and the wages on offer for alternative work, chooses to keep it’s children away from school and working on the farm.

It is largely for this reason that many people advocate what they call “economic rights”.  Although there are various versions of this (e.g. minimum wages, the welfare state, etc.), you can think of them as a government, on behalf of the entire population, instituting a guaranteed minimum income.

Now, while there are strong moral arguments for such a guarantee (which I fully support and agree with), this is not a right.  This is a mandated transfer of income from high-income citizens to low-income citizens.  For the rich, it is an obligation (the opposite of a right) and for the poor, it does not directly increase the range of choices available to them.  Instead, it indirectly increases that range by relaxing one of their constraints.

I say again:  I fully support providing a minimum income to all people by means of a welfare state; nobody should live in poverty.  But this is not a right.  It is a moral duty.  Calling this an “economic right” is a deliberate obfuscation for marketing purposes.  People pay more attention and money when a person’s “rights” are being denied than when they simply have a moral obligation to help.

I love the work done by UNICEF. I think they are just about the best NGO on the planet. My wife and I donate money to them. They make an express point of telling you how much of the money you give will go to administration costs or to more fundraising.

I just wish they could raise those funds without confusing things by saying that Aklima’s right to education is being denied to her.  I recognise that they have to.  I just wish that they didn’t.

Note to self: holidaying in Greece will soon be cheap

Megan McArdle directs the world to this piece in the FT.  From the FT article:

The European Commission said on Tuesday it would endorse Athens’ plan to bring back under control the public sector deficit, which last year reached almost 13 per cent of gross domestic product.

Under a three-year plan, the Greek government seeks to cut the national budget deficit to less than 3 per cent of GDP by the end of 2012.

and:

In response to criticism that earlier plans had not included sufficient spending cuts, Mr Papandreou also announced an across-the-board freeze in public sector wages which, together with cuts in allowances, would reduce the public sector wage bill by 4 per cent. The government has also pledged to raise the retirement age.

If the Greek government can achieve this without massive, nation-wide strikes, I’ll be terrifically impressed.  Megan’s comments:

Everyone is expressing optimism. But while this sort of belt-tightening is necessary for Greece to stay in the EU, it’s going to come at a huge cost. Greece is already in recession–that’s why its budget problems loom so large–and the fiscal contraction will only make them deeper. Meanwhile, the EU will be setting its interest rates to meet the needs of larger, healthier members (and inflation-hawk bondholders). Tight fiscal and monetary policy means a long, painful period ahead for the Greeks.

This is the dilemma that faced Argentina with its monetary peg to the dollar; ultimately, it led to devaluation and default. We will see if Greece can whether [sic] it better.

I don’t think that this sort of belt-tightening is strictly necessary in the near term.  Germany will, again, fund a bail-out if it really comes down to it because, if nothing else, the loss to Germany of a member of the EU dropping the currency is greater than the loss to Germany of paying for Greece’s debt.

It’s clearly necessary in the long term that Greece get it’s fiscal house in order, but since they’re in such a severe recession, this isn’t really the time to do it (financial market pressure aside).  This is, in essence, the same debate that is gripping America, although there the pressure to address the deficit is coming from a successful political strategy of the opposition rather than, much as that same opposition might like, pressure from the markets.

Ultimately, what the EU needs is individual states to be long-term fiscally stable and to have pan-Europe automatic stabilisers so that areas with low unemployment essentially subsidise those with high unemployment.  Ideally it would avoid straight inter-government transfers and instead take the form of either encouraging businesses to locate themselves in the areas with high unemployment, or encouraging individuals to move to areas of low unemployment.  The latter is difficult in Europe with it’s multitude of languages, but not impossible.

In a perfect world where all regions of the EU currency zone were equally developed, this would simply replace the EU development grants.  But this isn’t a perfectly world …

On China

Menzie Chinn emphasises that for the purposes of estimating country shares in global GDP, it is necessary to think of them in nominal terms.  On that basis, China is large, but only half the size of the Euro zone and well under half the size of America.  Therefore, he implies, an increase in demand from China won’t really contribute as much to global growth as people might be hoping.

Nevertheless, people do seem to be wondering about China as an engine of global growth in demand.  The reason is simple:  Despite a near catastrophic collapse in world trade, China’s economy is still growing while those of  other export-oriented countries like Japan or Germany are falling precipitously.

Clearly part of the reason for the continued Chinese growth, like in Australia, is the successful use of a fiscal stimulus to boost local demand (the Australian rebound was also helped by the fact that, by not manufacturing much, their decline in investment was offset by a fall in imports and (price) changes in natural resource exports occur with a significant lag).

Brad Setser has explored the Chinese stimulus a little.  He writes:

I initially underestimated the magnitude of China’s stimulus by focusing on the (fairly modest) change in the government’s fiscal balance. It is now clear that the majority of China’s stimulus has been off-budget: the huge increase in lending by state owned banks mattered far more than the change in the budget of the central government. The expected loss on these loans can be considered a form of fiscal stimulus.

Which is a fascinating way to conduct government business.

Ecuador defaults. Wait, no. Yes. Maybe?

Felix Salmon points out the absurdity of the situation:

A couple of major developments on the Ecuador front: yesterday, finance minister Elsa Viteri came out with the rather stunning decision that the country would make the coupon payments on its 2015 global bonds — despite deciding to default on the 2012s and the 2030s. And today, the Ecuador CDS auction closed at 31.375%, meaning that anybody holding an Ecuador CDS will receive 68.625 cents on the dollar.

Viteri’s decision opens up a major legal battle: there’s no doubt that Ecuador’s legions of creditors will attempt to attach those coupon payments the minute they arrive in the US. And I, for one, can’t imagine for a second that holders of the 2012s and the 2030s will take Ecuador up on any forthcoming offer to buy their bonds back at 30 cents on the dollar when the country is happily paying the 2015s in full.

This is not the first time Ecuador has tried to pay some foreign creditors without paying others who are pari passu. Ten years ago it tried a very similar trick with its Brady bonds — with disastrous results. But I don’t think that Ecuador has any grand strategy here; instead, the most likely hypothesis is that a well-connected financier has greased enough palms to make sure that he gets paid out on both his 2015s and his credit default swaps.

What all this means in practice is that Ecuador is now behaving so erratically that there’s no point even attempting to deal or negotiate with the present administration in anything like good faith. Instead, the holders of the 2015s will thank their lucky stars and hope that they actually receive their money; the professional vultures will be spending a lot of time in federal court in lower Manhattan; and most of the rest of the holders of the 2012s and the 2030s will simply wait for the next Ecuadorean president to come along. Because this one just isn’t acting logically.

*sigh*

When can social change occur?

Somebody much smarter than I am was kind enough to read my little post on Endogenous Growth Theory.  At lunch today, they drew attention to this item that I mentioned:

I’m not aware of anything that tries to model the emergence of ground-breaking discoveries that change the way that the economy works (flight, computers) rather than simply new types of product (iPhone) or improved versions of existing products (iPhone 3G). In essence, it seems important to me that a model of growth include the concept of infrastructure.

The question was raised:

Could it be that times of significant social change have a tendency to coincide with with the introduction (i.e. either the invention or the adoption) of new forms of infrastructure? [*]  A new type of mobile phone hardly changes the world, but the wide-spread adoption of mobile telephony in a country certainly might change the social dynamic in that country.

It’s something to ponder …

[*] My intelligent friend is not an economist and would probably prefer to think of this as a groundbreaking discovery rather than just the development of a new type of infrastructure.

New Scientist is loopy

New Scientist has a feature this week blaming the unsustainable destruction of the environment on an obsession with economic growth and calling for a move to a growth-free world.  The answers to the questions raised by the collection of articles (all essentially repeating each other) are straightforward and widely recognised:

  • As the supply of something dwindles or the demand for it rises, the price of that thing will rise.  If we run low on some particular natural resource or our demand for it at the current price proves greater than the supply, the price will rise.  That will cause demand to fall and will spur innovation in searching for an alternative.  Trains in Britain first ran on coal-fired steam engines.  Eventually the price of coal rose too high and they switched over to diesel.  The price of oil was going up too, so after that they moved to electric engines.  The transitions aren’t perfectly smooth, I’ll grant you – there are discrete jumps that can make it a bumpy ride – but it does happen.
  • Externalities exist, both good and bad.  Actions that come with positive externalities ought to be subsidised.  Actions that come with negative externalities ought to be penalised.  We’re producing too much carbon dioxide?  Make the polluters pay.  Whether it should be through taxes or a trading system is a matter of debate, but bring it in.  We’re over-fishing in the North Atlantic?  Impose a tax directly on the fishermen for every fish they catch.  When the cost of doing a bad thing rises, people do it less and innovate to find an alternative.
  • Yes, extreme inequality is a Bad Thing ™.  It’s true that for some time we’ve had worsening inequality because of low growth among the poor and high growth among the rich, but that doesn’t mean that growth is bad per se, only that the composition of growth is around the wrong way.  It is far better to have low growth for the rich and high growth for the poor (so they catch up) than to have no growth at all and rely entirely on redistribution.  Redistribution should happen, yes, but primarily for the purposes of enabling the poor to grow faster.  Have the rich pay for the health care and education of the poor.

You don’t think this all this is possible?  Of course it’s possible.  Here is an article from Der Spiegel from April 2008 talking about solar power and the Sahara desert.  Here is a map from that same article:

The caption reads:  “The left square, labelled “world,” is around the size of Austria. If that area were covered in solar thermal power plants, it could produce enough electricity to meet world demand. The area in the center would be required to meet European demand. The one on the right corresponds to Germany’s energy demand.

If the cost of coal- and gas-fired electricity production were high enough, this would happen so fast it would make an historian’s head spin.

Sing it from the rooftops

A bunch of serious economists have been pointing to this comment by Paul Collier. It is so good that I’m going to reproduce it in full:

The sharp increase in the world price of staple foods is an inconvenience for consumers in the rich world, but for consumers in the poorest countries, especially in Africa, it is a catastrophe. Despite the predominance of peasant agriculture, most African countries are net food importers and food accounts for over half of the budget of low-income households. This is the result of decades of agricultural stagnation combined with growing populations. Although many of the net purchasers are rural, evidently the problem is at its most intense in the urban slums. These slums are political powder kegs and so rising food prices have already triggered riots. Indeed, they sow the seeds of an ugly and destructive populist politics.

Why have food prices rocketed? Paradoxically, this squeeze on the poorest has come about as a result of the success of globalization in reducing world poverty. As China develops, helped by its massive exports to our markets, millions of Chinese households have started to eat better. Better means not just more food but more meat, the new luxury. But to produce a kilo of meat takes six kilos of grain. Livestock reared for meat to be consumed in Asia are now eating the grain that would previously have been eaten by the African poor. So what is the remedy?

The best solution to a problem is often not closely related to its cause (a proposition that that might be recognized in the climate change debate). China’s long march to prosperity is something to celebrate. The remedy to high food prices is to increase food supply, something that is entirely feasible. The most realistic way to raise global supply is to replicate the Brazilian model of large, technologically sophisticated agro-companies supplying for the world market. To give one remarkable example, the time between harvesting one crop and planting the next, in effect the downtime for land, has been reduced an astounding thirty minutes. There are still many areas of the world that have good land which could be used far more productively if it was properly managed by large companies. For example, almost 90% of Mozambique’s land, an enormous area, is idle.

Unfortunately, large-scale commercial agriculture is unromantic. We laud the production style of the peasant: environmentally sustainable and human in scale. In respect of manufacturing and services we grew out of this fantasy years ago, but in agriculture it continues to contaminate our policies. In Europe and Japan huge public resources have been devoted to propping up small farms. The best that can be said for these policies is that we can afford them. In Africa, which cannot afford them, development agencies have oriented their entire efforts on agricultural development to peasant style production. As a result, Africa has less large-scale commercial agriculture than it had fifty years ago. Unfortunately, peasant farming is generally not well-suited to innovation and investment: the result has been that African agriculture has fallen further and further behind the advancing productivity frontier of the globalized commercial model. Indeed, during the present phase of high prices the FAO is worried that African peasants are likely to reduce their production because they cannot finance the increased cost of fertilizer inputs. While there are partial solutions to this problem through subsidies and credit schemes, large scale commercial agriculture simply does not face this problem: if output prices rise by more than input prices, production will be expanded because credit lines are well-established.

Our longstanding agricultural romanticism has been compounded by our new-found environmental romanticism. In the United States fears of climate change have been manipulated by shrewd interests to produce grotesquely inefficient subsidies for bio-fuel. Around a third of American grain production has rapidly been diverted into energy production. This switch demonstrates both the superb responsiveness of the market to price signals, and the shameful power of subsidy-hunting lobby groups. Given the depth of anti-Americanism in Europe it is, of course, fashionable to criticize the American folly with bio-fuels. But Europe has its equivalent follies.

First, the European Commission is now imitating the American bio-fuels policy. At present the programme is small enough to be unimportant, but we need to pull it back before it does real damage. We have surely learnt enough about European agriculture to realize how important it is to kill this incipient scam before we are engulfed by it. But the true European equivalent of America’s folly with bio-fuels is the ban on GM. Europe’s distinctive and deep-seated fears of science have been manipulated by the agricultural lobby into yet another form of protectionism. The ban on both the production and import of genetically modified crops has obviously retarded productivity growth in European agriculture: again, the best that can be said of it is that we are rich enough to afford such folly. But Europe is a major agricultural producer, so the cumulative consequence of this reduction in the growth of productivity has most surely rebounded onto world food markets. Further, and most cruelly, as an unintended side-effect the ban has terrified African governments into themselves banning genetic modification in case by growing modified crops they would permanently be shut out of selling to European markets. Africa definitely cannot afford this self-denial. It needs all the help it can possibly get from genetic modification. Not only is Africa currently being hit by rising food prices, over the longer term it will face climatic deterioration in the context of a rapidly growing population.

While the policies needed for the long term have been befuddled by romanticism, the short term global response has been pure beggar-thy-neighbour. It is easier for urban slum dwellers to riot than for farmers: riots need streets, not fields. And so, in the internal tussles between the interests of poor consumers and poor producers, the interests of consumers have prevailed. Governments in grain-exporting countries have swung prices in favour of their consumers and against their farmers by banning exports. These responses further politicize and fragment an already confused global food market. They increase the risks of investing in commercial-scale food production and drive up prices further in the food-importing countries. Unfortunately, trade in agriculture has been the main economic activity to have resisted being subject to global rules. We need stronger and fairer globalization, not less of it.

What can I say?  Just this:  Amen.

*sigh* (Zimbabwe)

This is from The Independent. It’s a fairly short article, so I’ll include it in full (all emphasis is mine):

Chinese troops have been seen on the streets of Zimbabwe’s third largest city, Mutare, according to local witnesses. They were seen patrolling with Zimbabwean soldiers before and during Tuesday’s ill-fated general strike called by the opposition Movement for Democratic Change (MDC).

Earlier, 10 Chinese soldiers armed with pistols checked in at the city’s Holiday Inn along with 70 Zimbabwean troops.

One eyewitness, who asked not to be named, said: “We’ve never seen Chinese soldiers in full regalia on our streets before. The entire delegation took 80 rooms from the hotel, 10 for the Chinese and 70 for Zimbabwean soldiers.”

Officially, the Chinese were visiting strategic locations such as border posts, key companies and state institutions, he said. But it is unclear why they were patrolling at such a sensitive time. They were supposed to stay five days, but left after three to travel to Masvingo, in the south.

China’s support for President Mugabe’s regime has been highlighted by the arrival in South Africa of a ship carrying a large cache of weapons destined for Zimbabwe’s armed forces. Dock workers in Durban refused to unload it.

The 300,000-strong South African Transport and Allied Workers Union (Satawu) said it would be “grossly irresponsible” to touch the cargo of ammunition, grenades and mortar rounds on board the Chinese ship An Yue Jiang anchored outside the port.

A Satawu spokesman Randall Howard said: “Our members employed at Durban container terminal will not unload this cargo, neither will any of our members in the truck-driving sector move this cargo by road. South Africa cannot be seen to be facilitating the flow of weapons into Zimbabwe at a time where there is a political dispute and a volatile situation between Zanu-PF and the MDC.”

Three million rounds of AK-47 ammunition, 1,500 rocket-propelled grenades and more than 3,000 mortar rounds and mortar tubes are among the cargo on the Chinese ship, according to copies of the inventory published by a South African newspaper.

According to Beeld, the documentation for the shipment was completed on 1 April, three days after the presidential vote.

Zimbabwe and China have close military ties. Three years ago, Mr Mugabe signed extensive trade pacts with the Chinese as part of the “Look East” policy forced on him by his ostracising by Western governments over human rights abuses. The deal gave the Chinese mineral and trade concessions in exchange for economic help.

The shadow Foreign Secretary William Hague called on David Miliband to demand a cessation of arms shipments.

A South African government spokesman Themba Maseko said it would be difficult to stop the shipment.

*sigh*

Farm subsidies promote terrorism

Well, maybe not directly, but it bears thinking about. It’s not a new idea, either, but I thought I’d put it out there anyway …

US and European farm subsidies artificially suppress world crop prices by causing American and European farmers to produce more than they profitably otherwise could. By the World Bank’s estimates, the prices of course grains, rice and wheat would rise by between 4% and 7% relative to other prices if all subsidies and other impediments to trade were removed (hat tip: Dani Rodrik).

That means that farmers in places like Afghanistan turn to other crops like poppies (for heroin). Since drugs are illegal, the farmers can only sell their crops through black (well, in Afghanistan, grey) markets that are controlled, America tells us, by people who support and funnel profits to the Taliban and al-Qa’ida.

Those Afghani farmers don’t really care what they grow. They just want to make a profit, like anybody else. How do we know this? Because when the price of crops goes up for other reasons, they happily started switching to planting wheat:

In parts of Helmand Afghan farmers are this year sowing wheat instead of poppy – not because they have suddenly been converted to the argument that producing heroin is not in the national interest.

Market forces have been the deciding factor – with wheat prices doubling in the past year, and the street price of heroin falling, it is now more cost effective to grow wheat.

So there you have it. If America was serious about fighting drugs and terrorism, it would cut it’s farm subsidies.
