A Gaia Economist Slips into Error

Molly Scott Cato writes (28 May) on ‘Gaian Economics’ HERE

‘All other green campaigns become futile without tackling the economic system and its ideological defenders. Economics is only dismal because there are not enough of us making it our own. Read on and become empowered!’

‘Less Osborne More Hobsbawm’

Advocates of a market view of the economy and proponents of further and faster globalisation both tend to seek inspiration from the work of Adam Smith, who is taken to be the founding father of market economics. Smith's work The Wealth of Nations, was published in 1776, only on the cusp of the industrial revolution and before its technological advance had had the chance to impact widely on social and economic structures.

The economist who better represents the theory that has come to dominate our modern world is rather David Ricardo, whose most famous work Principles of Political Economy and Taxation was published in 1817, some 40 years after that of Smith, and whose work set the parameters for the world of laissez-faire capitalism and export-led growth that we inhabit today. Ricardo was attempting to theorise the economic reality of a world where labour and land were made subject to market forces, as they had been to only a limited extent in Smith's day.

In an excellent article in the New Statesman back in March, Robert Skidelsky made clear George Osborne's debt to Ricardo, whose economic theories he rather brutally summarised in the following phrase: 'It goes like this: the private sector creates wealth and the government squanders it. The smaller the government – the less it taxes and spends – the more the economy will thrive.' Moreover to a Ricardian there is no fundamental distinction between taxation and government borrowing: borrowing is merely deferred taxation.

This is an article of faith, unsupported by empirical evidence. …

… Economics is a complex system, where numerous variables interact in ways that can never be predictable. This is why jokes about one-armed economists are just foolish: there will always be a multitude of answers to every question and predicting the future is a mug's game. Hence the wise economist leaves his options open, and makes sure that the politicians he is advising do the same.’


Comment
A preliminary observation: Molly (the name by which she writes, so I am not being patronising) adopts the label of economics as the ‘dismal science, and “everyone knows that economics is the dismal science [and] almost everyone knows that it was given this description by Thomas Carlyle, who was inspired to coin the phrase by T. R. Malthus's gloomy prediction that population would always grow faster than food, dooming mankind to unending poverty and hardship.”

However, the facts are different and Molly ought to know the truth about the use of ‘the dismal science’ label, and I assume she does not know, otherwise if she did know she would be ashamed:

“Carlyle's target was not Malthus, but economists such as John Stuart Mill, who argued that it was institutions, not race, that explained why some nations were rich and others poor. Carlyle attacked Mill, not for supporting Malthus's predictions about the dire consequences of population growth, but for supporting the emancipation of slaves. It was this fact—that economics assumed that people were basically all the same, and thus all entitled to liberty—that led Carlyle to label economics "the dismal science."

It was this fact—that economics assumed that people were basically all the same, and thus all entitled to liberty—that led Carlyle to label economics "the dismal science.
" Quoted from: David M. Levy and Sandra J. Peart , 22 JANUARY 2001: “The Secret History of the Dismal Science. Part I. Economics, Religion and Race in the 19th Century” HERE:

Carlyle’s bitter attack on Mill came from disgraceful and scurrilous pamphlet entitled: "An Occasional discourse on the Negro Question" 1849 (which is the polite version – it was originally called ‘on the N----- Question’), and was written by the 'great' Thomas Carlyle.

This episode shows that liberal-minded people do not have a monopoly of the social virtues, which is also clear from today’s representatives, such as Molly, or, indeed, the distinguished historian, Professor Eric Hobsbawm in her title.

On the substance of Molly’s article, I am not in total support of her side-blast at David Ricardo, or more pointedly, I have more fundamental disagreements over Ricardo’s influence on economics than an alleged error of George Osborne, the British Chancellor.

Smith’s criticized the consequences of the discovery by government that it could add to its capacity for extracting revenue from taxation from some of its citizens (always unpopular) by borrowing, which was less painful politically, governments soon realized. In fact, because they often needed to borrow to fund their dynastic wars, governments displaced loan repayments and their interest costs to the future, which caused yet more borrowing and interest burdens to future taxpayers.

It is not clear to me the significance of Professor Skidelski’s or Rucardo’s point about Taxation and Borrowing. I do know that the habit of medieval Kings who simply expropriated their lenders when it was expedient to do so is not available to modern governments under the rule of law and that defaulting on debts likewise has downsides, including morally too.

However, Ricardo’s main malign error concerned his analytical devices, which when taken up by the neo-classical economists from the 1870s, especially the mathematically obsessed, has been quite damaging. In order to get determinate ‘solutions’ the assumption of decreasing returns from agricultural examples lead to uni-dimensional economics, which produced fine equations, wonderful graphs, and, eventually, an absence of people from economics, perhaps the most significant loss to unreality, yet attempted by its practitioners. In the extreme, the triumph of ‘general equilibrium’, seen as the pinnacle of economics as a science, is actually a minor triumph of analysis that does not conform (i.e., explain) social reality.

Disequilibrium rules. Equilibrium is at best partial – never general as the persistence of temporary relapses into recessions and depressions, followed by temporary booms, shows. Whether this is ‘good’ or ‘bad’ thing is less important than the recognition that it happens. The question is whether societies can live with these events, with the subsequent question of whether- and more particularly ‘which’ - political interventions to ‘correct’ these events makes things ‘better’ or ‘worse’.

Adam Smith made (very) few predictions. His almost entire approach was historical – how did we get to where we are – and not predictive. If anything he remained sceptical of predictions and of the likelihood that political elites would choose the appropriate policies to remove existing anomalies –they were, more often, the cause, not the cure, of errors in economic management (mercantile political economy). I confess, not to having much faith in ‘gaia economics’, or other would be salvation (New Economics Foundation, etc.,).

But I mean no malice. I will read what Molly writes, and wait and see.

Further Comments on Jeff Weintraub and Adam Smith's Explanations of Rising Real Wages

Dear Jeff Weintraub

Thank you for your interesting response to my comments on your debate with your students (incidentally, I admire your excellent scholarly dialogic debating style, intended to help your students think for themselves rather than just thoughtlessly accept what they are taught).

Incidentally, I was unable to send my comments direct to you because I could find no contact email address on your site (mine is: gavink9ATgmailDOTcom).

I accept that among the requirements of teaching about the classical economists it must include covering Ricardo et al, and it is clearly necessary to be comprehensive. However, I find the inclusion of Ricardo in discussions of Adam Smith’s meanings is often, at least for me, exasperating, as Ricardo’s theoretical ‘improvements’ showed he had a quite different understanding of what Smith’s political economy was about. Ricardo is popular as a ‘theorist’, with several modern economists, with whom I maintain friendly relations (e.g., Terry Peach of Manchester), but I find the gap between Ricardo on Smith’s historical approach is near impossible to bridge (though, of course, that is no reason ever to fall out over it).

I am sure that we would agree on quite a lot about Smith if we were in the same room. If it comes down to explaining “whether Smith has a satisfactory theoretical explanation for how and why …. in a market economy… [it produced] … a broad-based improvement in most people's standard of living”, I would start with what Smith was saying and never, from bitter experience, with what modern economists, including Ricardo, say he said or meant.

I must defer to you in agreeing that he did not state his ideas or method explicitly in a manner acceptable to modern theorists. There are explanations in WN, but it is wrapped-up in non-formal language, and we have to dig it out, so to speak. It is worth the trouble of doing so. Better that way in my view than adopting ‘theoretical reasoning’ that turns out to be wrong (biological subsistence only) and ‘clarifiers’ used to predict immiseration.

The view outside Ricardo’s windows (and from Marx and Engels’s even loftier perches) was quite depressing and misleading. The new urban, not to say wretched, poor were growing faster numerically from immigration (Ireland) and the ‘attraction’ of the cities from the land (then no rural paradise, to put it mildly) than the capacity of new forms of manufacturing and trade activities to provide employment, from which real incomes could rise (6p a day for six year-olds beat nothing a day). Though evidence of rising real incomes from 1760-1860s onwards conforms to the historical trends identified by Smith. This often, but not always, miserable introduction to the commercial economy is an experience all too familiar in parts of the world today, which many ‘westerners’ do not appreciate – our ancestors paid their heavy ‘admission’ price to the Age of Commerce, not us.

Output was sold to the population in ever-greater amounts with slowly rising quality (differentiated, of course, across the income classes). Take a simple indicator: the growth in the manufacture of ‘conveniences and amusements’ in the form of children’s toys from the 1750s onwards. What somebody earned as wages from making, they spent to purchase other ‘necessaries and conveniences’, and, on occasion, second- or third-hand ‘amusements’ of life. [Smith in WN reports that King James VI and 1st’s former wedding-bed was an ‘ornament’ at an alehouse in Scotland (WN II.iii.39: 347).]

All this, and much else, was over-shadowed by all the very real oppressive social interventions, despite which, market relationships had produced and continued to produce broad-based, if initially minute, improvements in growing numbers of people's standards of living over several decades and centuries. The Malthusian trap was foiled for the first time in millennia. There were, however, many laws and political barriers left to reform – most waited until the 20th century, but much are still with us, plus plenty of new ones.

There was also ‘middle-ranking’ (‘wives of Aldermen’, TMS I.iii.2.6.8: 57) rank, place and prejudices operating against common folk getting ‘above themselves’ and imitating the dress sense and habits of their ‘betters’ (mocked by US folk lore in ‘Yankee Doodle’ and his feathered hat, which he called ‘Macaroni’; unhappily, a most unlikely scene in 18th-century Scotland).

As small manufacturing gave way to workshops, and the numbers of skilled labourers increased, plus new trades (mechanization) and new supervisory posts proliferated, real incomes increased for new occupations. The Mechanics Institutes movement (teaching young artisans to work with new skills in chemistry, physics, maths, and designs in the new industries) began to appear in the 1800s (among them the predecessor of Heriot-Watt University in 1821).

The ‘pinhead’ example should be placed in context. New working methods required new mechanical apparatus (beautifully illustrated and detailed in Diderot’s Encyclopedia, 1751-77), which required new manufacturing capacity, and was a process that grew and accelerated in new industries from then on. These cost more – much more after steam power was harnessed – with higher demand for the necessary skills and education to design and make them. These also raised the real wages of new grades of labour and undermined the survival-only subsistence pessimism of Ricardo (and Malthus). Increasing, not decreasing, returns to scale became a feature of the non-agricultural economy, not really challenged until the 1920s, nor really integrated into growth theory until Romer in the 1980s – so much for ‘theorists’ not catching up with the real world.

The absence in Smith of a ‘theoretical explanations’ for all these events in the real world is worth setting good students the task of thinking about (it should make them even better students). But I am wary of changing from ‘what works in practice, but may not work in theory’ (Adam Smith’s political economy) into an exercise of adopting something that ‘works in theory, but definitely does not work in practice’ (including the dead-end of diminishing returns). However, I accept your challenge and will return to the subject in due course.

I am glad that I spotted your article and was able to join a debate if only from the sidelines. Good students deserve good teachers, and on this evidence, fortunately, Daniel Albornoz and David Kanter, have found one.
