The FT goes green
Clearly Beyer does not appreciate the irony of his statement. No previous type of society would be rich enough to provide sufficient waste food for his like to live on. His whinge sets the tone for the rest of the magazine including its interview with James Lovelock and a piece on the efforts of the village of Ashton Hayes to go carbon neutral.

On food and life expectancy
FOOD FOR THOUGHT: India Knight (Comment, last week) writes: “Our ancestors existed on red meat, and there is no evidence to show they all died of breast cancer.” But almost all of them died before the age of 30. Statistically, they would have had little risk of breast cancer relative to all life’s other dangers whether they ate red meat or not. Even by 1800 life expectancy was only about 35 years. She also says “organic food is the way forward”. Our ancestors only ate this along with fresh air and plenty of physical activity – and still died by 30. – Dr Ian Horman, co-author of 2 Million Years of the Food Industry, Blonay, Switzerland.
Happy Danes
“Women generally classed themselves as happier than men, while the old and young tended to be happier than people in their middle years.
“The Cambridge team has now begun to analyse what makes people in some countries happier than others. One of the most consistent trends is that those with the highest levels of happiness also reported the highest levels of trust in their governments, the police and the justice system, as well as those around them. Happier people also tended to have plenty of friends and acquaintances, as well as at least one very close friend, or a partner.”
A (highly mathematical) paper co-authored by Dr Corrado on the subject is available on the Cambridge University website.

An authoritarian happy place
Bhatan. Inconvenient, that it, for those who praise the Himalayan kingdom for having Gross National Happiness, rather than GDP, as a national goal:
* The Bhutanese are obliged to wear knee-length tunics and full-length
dresses in public.
* It is run by a council of royally approved ministers.
* Parliament¹s members are either elected, Buddhist clergy or picked by the
king.
* The Nepali speaking and Hindu minority has suffered discrimination. They
were forced to wear Buddhist costume and prove their right to citizenship by
obeying strict rules.

Book review on the new economics
Diane Coyle is annoyed. She argues with considerable justification that economics, the subject in which she has immersed herself for her entire adult life, is caricatured by critics. Those who attack the discipline often do so from a position of ignorance. They are unaware of the huge advances economics has made in the past 20 years.
The Soulful Science is Coyle's attempt to set the record straight. It is essentially an overview of the key developments in economic thought over the past two decades. With a PhD in economics from Harvard she has the theoretical background to understand often arcane debates. And as a former economics journalist she has the ability to translate them into lucid language.
Summarising, what is itself, a summary of a huge range of ideas is a difficult task. But much of the book focuses on the core idea of "rational economic man". Neo-classical economy theory was based on the idea that humans were utility maximising, unremittingly rational and had access to perfect information. In other words, humans were assumed to be Vulcan - or at least half-Vulcan - like Star Trek's logical Mr Spock. Coyle explains how each of these core assumptions has come under attack in the new economics.
The idea of utility maximisation is an old one. It assumes that humans are motivated by a desire to maximise their wealth. As a result of this drive, it is argued, society benefits.
Coyle shows how this core assumption has come under attack in recent years. Environmentalists argue that measures such as GDP do not take into account environmental damage to the economy. Some economists, such as America's Robert Frank and Richard Layard in Britain, argue that rich countries should pursue happiness rather than further affluence. Others, such as Barry Schwartz, have argued that individuals suffer as a result of the vast amount of consumer choice available.
The idea of human rationality has also been called into question. Economists have increasingly drawn on insights from psychology which show that humans often do not behave rationally. This insight has opened up behavioural economics as an important new field of study with behavioural finance as a key sub-branch. In 2002, Daniel Kahneman and Vernon Smith were awarded the Nobel price for research in this area.
Research into the economics of information has also yielded Nobel prizes. In different ways Joseph Stiglitz, George Akerlof and Michael Spence examined the implications of some people having access to better information than others. Their insights have helped governments to create new markets, such as those involved in trading carbon.
While Coyle is right to argue that critics need to be aware of these developments, it does not follow that the discipline is beyond reproach. On the contrary, both the new-style economists and the old-style neo-classical economists share many key assumptions, despite their differences.
The idea of "economic man" illustrates this point. Both accept as a starting point the idea that the economy, and society more generally, is essentially an aggregate of individuals. Different generations of economists differ over the exact character of the individuals involved but all sides tend to be imbued with this individualistic starting point.
In contrast, classical political economy - including the likes of Adam Smith, Karl Marx and David Ricardo - had a much greater sense of the social. It viewed society as more than a collection of individuals - the human world had to be understood in terms of the web of social relations around which life is organised. For example, organising society around the principle of profitability had direct consequences for the operation of laws that govern social interaction.
The current generation of economists use the word "social" a lot, but the sense in which they use it is limited. In contemporary parlance the term "social" refers to interpersonal relations. For example, "social networks" means the personal relationships between individuals. In contrast, "social" in the older sense of the term referred to the set of relations around which production and consumption were organised.
This diminished sense of the social helps to explain why contemporary economics tends to be so ahistorical. Economists can happily make generalisations about the operation of institutions 10 years ago, 1,000 years ago - even 10,000 years ago. They fail to see what is specific to market relations and underestimate the importance of changes over time.
Coyle's discussion of utility is a perfect example of this lack of sensitivity to historical shifts. The shift away from emphasising utility to one focusing on happiness is not primarily the result of theoretical development by economists. The economists' discussion reflects a broader disaffection with economic growth and prosperity in society at large. Since the 1970s it has become increasingly common for the benefits of mass affluence to be called into question. This anxiety about popular prosperity then, itself, has to be explained in terms of broader social changes.
From this wider perspective it is clear that Coyle is wrong to portray the emphasis on happiness as more human than the focus on economic growth. On the contrary, the immense benefits of a society based on affluence have made it easier for humans to realise their potential. In contrast, the happiness agenda reduces humans to the level of cows chewing grass in a field. The advocates of happiness would have us pursue individual contentment in the narrowest sense of the term rather than more demanding objectives.
The Soulful Science should be read by anyone who wants a lucid and authoritative introduction to contemporary economic thought. But the limitations of the new economics have themselves to be fully investigated.

America’s economic decline becomes clear
The increasingly popular idea that the world is "decoupling" from America is misleading. It is not that the integration of the world economy is lessening in any way. The real trend is for a decline in the relative importance of America in the global economy.
Proponents of the decoupling thesis argue that the world is becoming less dependent on America. Two weeks ago the International Monetary Fund argued that Asia could weather an American soft landing. Last week Merrill Lynch went even further and argued that Asia could ride an American recession without any significant problems.
Their evidence is essentially that Asia in particular, and the rest of the world in general, is already weathering an American slowdown. In addition, both Asia and Europe are becoming more integrated regions in trade terms. China is becoming central to the new Asian economy while Europe is becoming increasingly integrated between its East and West.
This misses the fact that the world is still closely linked to America in other ways. Most notably there are huge capital flows between America and the rest of the world.
More importantly, America's relative decline should have already been apparent before its recent slowdown. As Fund Strategy has previously argued the idea that America was the locomotive of global growth earlier this decade was always misleading. It was primarily Asian production that was subsidising American consumption. Asia has long been the engine driving the world economy (see Fund Strategy book review, February 6, 2006).
What has happened recently is that the declining relative importance of America has simply become more obvious. Although America is still the world's largest economy it no longer has the overwhelming weight it once enjoyed. The balance is shifting towards Asia while the developing world is growing in relative importance compared with the advanced nations.
As a result of these shifts a new world economy is emerging. China is taking a far larger role than in the past. Asia and Europe are both becoming more internally integrated regions. The developing countries have more weight in global economic affairs. And America, increasingly in hock to the rest of the world, is moving towards losing its pre-eminent position.

Migration plays key role in development
“Migrants worldwide sent home an estimated $300 billion last year — nearly three times the world’s foreign-aid budgets combined. These sums — “remittances” — bring Morocco more money than tourism does. They bring Sri Lanka more money than tea does.
“The numbers, which have doubled in the past five years, have riveted the attention of development experts who once paid them little mind. One study after another has examined how private money, in the form of remittances, might serve the public good. A growing number of economists see migrants, and the money they send home, as a part of the solution to global poverty.”
This point is alluded to in my 17 April post on the globalisation of labour chapter in the latest World Economic Outlook from the International Monetary Fund. It is examined in more detail in an essay in chapter two (PDF) of the April 2005 World Economic Outlook.

Inequality fear in Latin America
“Perhaps the region’s greatest ongoing concerns are social and economic inequalities – which remain the most significant in the world. Globalization continues to drive both real inequalities, via income stratification within the region, and perceived inequalities, as local populations observe fast growth elsewhere. Many Latin Americans continue to suspect that global prosperity is leaving them behind, a perception seemingly resistant to decreases in absolute poverty. Political reform, the encouragement of small and medium enterprises and, crucially, education, remain the region’s best mitigators of inequality-driven populist backlash.”
The report echoes a discussion organised by the Organisation of American States held earlier this year. See my 13 March post.

Newsweek balanced on climate change
“Fairly or not, the tilt is destined to favor the countries of the rich North, to the detriment of the poorer South. Within a few decades or so, a balmy Greenland may again deserve its name.
“Russia, long a half-frozen terra incognita, will find its interior frontiers thrown wide open as the Siberian tundra turns to fertile prairie. Scorching heat and drought may devastate agriculture along the equator. The rain forests of the Amazon could be savanna by 2100, according to Brazilian researchers. The vast Sahara will grow ever larger. But America and other rich nations will be left relatively unscathed, because they are removed from equatorial regions that will be hardest hit, and wealthy enough to adapt.”
The newsmagazine also alludes to the possibility that the developing world could adapt to climate change if it has the necessary resources. “The problem is poverty, not climate,” it says. Even the most vulnerable countries, such as Bangladesh, can cope with climate change if they develop fast enough.

Globalised labour is great benefit to all
One of the most important but least discussed topics in understanding the world economy is the globalisation of labour. It is therefore welcome that the International Monetary Fund has included a chapter on the subject in its key twice-yearly World Economic Outlook.
The IMF estimates that the effective global labour force has risen fourfold over the past quarter century. Most of this increase has taken place since 1990.
There are several channels through which this globalisation process occurs. Increasing trade, offshoring of production and migration all contribute to a more global role for labour.
The objections to this process are unconvincing. Labour's globalisation should be supported as an unqualified good. Many of the objections are based on the common misconception that economics is a zero-sum game. In other words, one person's gain is - erroneously - seen as another person's loss.
In reality the globalisation of labour represents a more efficient allocation of resources in the global economy. The size of the world economic pie can grow larger because labour is distributed where it is needed. Everyone can benefit from the growth this process generates.
Critics who attack globalised labour for resource shortages blame the wrong people for such problems. For instance, it is not immigrants who are to blame for the chronic shortage of reasonable housing in the south east of England. Successive governments have discouraged housebuilding through excessive regulation. Often this takes the form of defending the "green belt" around London and other environmental regulations. In the name of defending the planet both migrant workers and the indigenous population have to rely on a stock of ageing and excessively expensive homes.
Another objection to globalised labour is cultural. The charge is that high levels of migrant labour will undermine the integrity of national cultures. Such views are insufferably parochial. The mixing of people from different backgrounds is a positive development. In any case, the similarities between people are far more important than the differences.
It should also be remembered that the globalisation of labour is immensely beneficial to developing countries. Remittances from overseas workers and the proceeds of international trade play a key role in the development process.

Global growth reducing extreme poverty
The number of people living below the $2 a day threshold is also falling. However, at 2.6 billion people it still accounts for almost half the population of the developing world.
Two related factors seem to be behind the drop in extreme poverty. First, the rapid rate of growth in developing countries overall in recent years. On average the rate of GDP growth per head has average 3.9% a year since 2000. Second, the spectacular growth of East Asia and China in particular.
Interestingly the World Bank seems keen to emphasise that other factors besides economic growth also play a role in poverty reduction. However, part of this discussion seems to be on relative inequality - a different although related question - rather than absolute living standards.

Tom Friedman calls for green patriotism
“Well, I want to rename “green.” I want to rename it geostrategic, geoeconomic, capitalistic and patriotic. I want to do that because I think that living, working, designing, manufacturing and projecting America in a green way can be the basis of a new unifying political movement for the 21st century. A redefined, broader and more muscular green ideology is not meant to trump the traditional Republican and Democratic agendas but rather to bridge them when it comes to addressing the three major issues facing every American today: jobs, temperature and terrorism.”
The underlying theme in Friedman’s piece is that environmentalism can be a unifying ideology for America: “a new green ideology, properly defined, has the power to mobilize liberals and conservatives, evangelicals and atheists, big business and environmentalists around an agenda that can both pull us together and propel us forward. That’s why I say: We don’t just need the first black president. We need the first green president. We don’t just need the first woman president. We need the first environmental president. We don’t just need a president who has been toughened by years as a prisoner of war but a president who is tough enough to level with the American people about the profound economic, geopolitical and climate threats posed by our addiction to oil — and to offer a real plan to reduce our dependence on fossil fuels.”
He concludes by calling for what he calls “an ethic of stewardship”: “Stewardship is what parents do for their kids: think about the long term, so they can have a better future. It is much easier to get families to do that than whole societies, but that is our challenge. In many ways, our parents rose to such a challenge in World War II — when an entire generation mobilized to preserve our way of life. That is why they were called the Greatest Generation. Our kids will only call us the Greatest Generation if we rise to our challenge and become the Greenest Generation.”
Friedman has a related documentary on "Green: The New Red, White and Blue" on the Discovery Channel and article in Foreign Policy on “the first law of petropolitics”.

Anti-corruption hurts poor countries
There are several reasons to object to anti-corruption. It strengthens Western interference in the affairs of poorer countries. It distracts from the need to find ways to promote economic development. And it encourages a corrosive climate of distrust.

Protectionist threat to global growth
The past few days have seen mixed news on the world economy. The bad news emanates from America while good news originates in emerging markets.
Probably the worst news is America's decision to impose tariffs on imports of "coated free sheet paper" from China. The Commerce Department has deemed that China is providing unfair subsidies to this industry. Therefore, so the argument goes, America needs to take action to level the playing field between the two sides.
Clearly America's move is symbolic. It is concerned about China's huge trade surplus with the US. The tariffs on paper are therefore designed to encourage China to curb its exports to the US or buy more American goods.
Some might argue America's recently announced free trade agreement with South Korea to an extent offsets its protectionist measures against China. But this is the wrong way to look at the move. The bilateral deal with Korea, giving it preferential access to the American market, is another form of protectionism. America rewards some countries and penalises others as part of a concerted trade policy.
It would be far better if America lived up to its rhetoric of free trade. In principle trading relations between different countries have the potential to benefit all parties in the relationship. Living standards can rise as each country focuses on what it can produce most efficiently.
In contrast, protectionism threatens to fracture the world economy. It could lead to a situation in which there is less trade, not more. As a result everyone, particularly the poorer countries, could suffer.
Fortunately some good news has offset the bad. Figures from the Asian Development Bank, in its annual Asian Development Outlook, forecasts GDP growth in developing Asian at 7.6% in 2007 and 7.7% in 2008. The two demographic giants of the region, China and India, together account for much of this growth.
Even better news is the expansion of the African economies. The continent looks set to grow by 5.8% in 2007 after its 5.7% in 2006, according to the United Nations' Economic Report on Africa 2007. It is growing from a meagre base but the trajectory is hopeful. The main worrying sign is its continuing dependence on primary commodity exports.
If only America, and the West in general, allows the emerging economies to continue to grow then everyone could benefit.

Urbanisation benefits the poor
It is true that an increasing proportion of the world’s poor are living in urban areas. But this trend is likely to be because of the growth of cities in absolute terms. About three-quarters of the developing world’s poor still live in rural areas.
The paper also looks at national and regional differences in patterns of poverty. It looks like it should repay closer examination.

Another climate change report
It was also striking that a New York Times leader followed the example of Britain’s Stern Review in arguing there is a choice between doing nothing – or “denial” – and an approach centred on managing energy demand. The Times argued that following last week’s supreme court decision and the publication of the new IPCC report: “One would hope that these events would shake President Bush out of his state of denial and add his authority to the chorus of governors, legislators and business leaders calling for an aggressive regulatory and technological response to the dangers of global warming.” The idea that there might be other ways to tackle climate change, notably bolstering energy supply, is not even considered.

On hedonic adaptation
There is nothing wrong with psychologists studying human happiness. But those who see happiness as a goal for humans to pursue are wrong. Many important and worthwhile enterprises – such as bringing up a family or learning another language – do not necessarily bring happiness. And the emphasis on individual contentment tends to downgrade the importance of prosperity to human welfare.

Noise and stench in Olde England
“The personal liberty of every freeborn Englishman and woman to spit, dump and defecate meant considerable misery for everyone. In the streets of London you would stumble over ‘the disagreeable Objects of bleeding Heads, Entrails of Beasts, Offals, raw Hides, and the Kennels flowing with Blood and Nastiness’. I never knew that ‘Mount Pleasant’, near Gray’s Inn, was actually a bitterly ironic name for a huge man-made heap of the most nauseous offal and ordure. It is now, of course, home to the Guardian newspaper.”
It should complement other books I have previously cited to help show how living conditions have improved enormously over the years. These include Judith Flanders’ Consuming Passions (Harper Press) on how few consumer goods we used to have (see 14 August 2006 post) and Lawrence Keeley’s War Before Civilization (Oxford UP 1997) on how murder was rife before modern times (see 30 July 2006 post).

America’s disappearing “middle class”?

Africa update
* Economic growth. Africa grew by 5.7% in 2006 after a 5.3% increase in 2005, according to the United Nations’ Economic Report on Africa 2007. Although this growth is relatively strong it should be noted that African economies are starting from an exceedingly low base. The report also makes the point that Africa still depends heavily on the export of primary commodities such as crude oil, metals and minerals.
* Aid. Aid to Africa was static last year and overall aid spending fell according to the Organisation for Economic Cooperation and Development. This is despite the fanfare around the Gleneagles G8 summit in 2005 when Tony Blair, the British prime minister, extracted pledges from governments to boost aid spending. Although the European Union, including Britain, increased spending both America and Japan spent much less.
It would be naïve to rely on Western governments to promote African government. However, these figures do show the hollowness of their promises on aid.
* Book. On Wednesday evening attended a University of Westminster seminar on The State They’re In given by Matthew Lockwood. The book is ostensibly an attack on the prevailing consensus on African development held by the likes of the British government and aid agencies. It argues that it is in the interests of the West to promote African developmental states, following the East Asian model, to help develop Africa.
Although the book is presented as a critique its conclusions are remarkably similar to the mainstream view. Lockwood sees African corruption as a big problem while ignoring the low horizons embodied in notions such as sustainable development. His book is also endorsed by the likes of Bob Geldof, Duncan Green (the head of research at Oxfam) and Shriti Vadera (an adviser to the British Chancellor).

US supreme court backs climate consensus
“It is a victory for a world whose environment seems increasingly threatened by climate change. It is a vindication for states like California that chose not to wait for the federal government and acted to limit emissions that contribute to global warming. And it should feed the growing momentum on Capitol Hill for mandatory limits on carbon dioxide, the principal greenhouse gas.”
In contrast the Wall Street Journal condemned what it called he “jolly green justices”:
“[I]sn't this something for Congress to decide? Global warming was already a hot topic in 1990, when Congress last amended the Clean Air Act. Yet it declined to enact amendments that would have forced the EPA [Environmental Protection Agency] to set CO2 emissions standards. The Members have since been engaged in periodic brawls over whether and how to regulate CO2, but, voila, the High Court has now declared that it shall be so.”
In my view the Journal is closer to the truth. Political decisions on how to react to climate change should be a matter for political debate. Science is best left to the scientists. Leaving such decisions to judges is the worst possible outcome.

Panic attacks “neo-liberal” model
“The importance of these comparisons is that they consistently show that countries with social democratic or corporatist models of capitalism have markedly higher levels of social well-being than those, such as the US and UK, with a liberal free-market model.
“Equally important, the reason for this is not that they have higher gross domestic product per head but that their social attitudes, objectives and policies are very different. Unlike the US and, since 1979, the UK, these countries attach great importance to social cohesion and, therefore, to equality of opportunity.”
It seems to me what Panic is missing is the need to raise the living standards of the poor in America and Britain still further. The need is for more growth rather than less. It is also striking that much of the discussion of well-being is underpinned by a fear of social breakdown.

Microfinance – a crack in the consensus
“Critics on the left charge that micro-finance privatizes social safety networks, while conservatives dismiss it as charity disguised as enterprise. Wonks weigh in with studies like "The Myths and Magic of Microcredit" and "Money Is Not Enough." Insiders turn on the industry. Loïc Sadou-let, a former World Bank economist who worked in microfinance in Guatemala, estimates that only about 300 of nearly 25,000 microlenders have reached financial "sustainability," meaning they are able to cover all costs.”
A critical essay by Thomas Dichter, an international aid expert, is also available on the Cato Institute website. In his view most such credit is likely to be use to fund consumption rather than investment.

Poverty debate in Britain – and more on US
Polly Toynbee, Guardian columnist and alleged expert on poverty, wrote a column complaining that too little attention is paid to poverty. What she missed is the fact that, as I have written previously on spiked, the poverty debate has not disappeared but recast in different terms.
The Economist wrote that the bargain that has existed for the past 20 years has to be failing. The rich are getting richer but the poor are not becoming better off too. It also quoted the Tories as saying that Britain is getting a more American pattern of income distribution without a corresponding rise in philanthropy.
On Spiked Rob Lyons pointed out that absolute living standards are rising even if relative ones are not. He also argued that the discussion of poverty has taken a more moral tone than in the past.
Meanwhile, the New York Times carried an article this week on a new analysis showing that the American income gap widened in 2005. The piece was based on a study of Internal Revenue Service data by Professor Emmanuel Saez, an economist at the University California, Berkeley, and Professor Thomas Piketty of the Paris School of Economics. The two authors have also done longer-term studies on income inequality in America.
