Talking proper

Oliver Kamm’s book Accidence Will Happen: The non-pedantic guide to English usage is a treat. I’ve always tried to write clearly about economics, a field strewn with jargon used in proper (as shorthand) and improper (as obfuscation) ways. I believe clear writing is a pretty reliable guide to clear thinking on the part of the author, and always liked George Orwell’s famous essay Politics and the English Language.


Accidence Will Happen is a heartfelt plea to respect the vitality of English as a living language whose usage changes. It scorns the “shibboleths” of grammar pedants and usage sticklers. (Orwell too argued against the tyranny of ‘standard English’, although his rules for writing are over-rigid in their turn.)

I largely agree with Oliver Kamm, even though I have a fondness for using ‘whom’ in the ‘right’ places and considering ‘data’ to be a plural. And this observation in the book strikes me as true and to the point: “Shibboleths are not rules of grammar, let alone marks of civilisation: they are a means of keeping divisions sharp. …. The sticklers’ clause is not about culture but about class.”

As an observer of teens who attended the local school, this class distinction is evident in the way the kids from middle-class families readily switch between standard English at home and the local London street dialect with their friends. And growing up myself in a working-class household in north west England, it was all too clear that losing one’s regional accent was a requirement for upward mobility.

The moral is: pause before you sneer at the greengrocer’s stray apostrophes.


Enlightenment values

I’ve been slowly reading The Shape of the New: Four Big Ideas and How They Made the Modern World by Scott Montgomery and Daniel Chirot. Slowly because it’s too big to carry in my bag on the tube. It’s an intriguing history of the modern world as shaped by – yes – Big Ideas. The authors’ argument is that: “Ideas have been among the primary forces behind modern history during the past three centuries.”

This isn’t a new argument in itself. In the context of economic history, Joel Mokyr’s The Gifts of Athena and his The Enlightened Economy give pride of place to ideas, then embodied in innovations.


And as Keynes famously said at the close of The General Theory:

“The ideas of economists and political philosophers, both when they are right and when they are wrong, are more powerful than is commonly understood. Indeed the world is ruled by little else. Practical men, who believe themselves to be quite exempt from any intellectual influence, are usually the slaves of some defunct economist. Madmen in authority, who hear voices in the air, are distilling their frenzy from some academic scribbler of a few years back. I am sure that the power of vested interests is vastly exaggerated compared with the gradual encroachment of ideas. Not, indeed, immediately, but after a certain interval; for in the field of economic and political philosophy there are not many who are influenced by new theories after they are twenty-five or thirty years of age, so that the ideas which civil servants and politicians and even agitators apply to current events are not likely to be the newest. But, soon or late, it is ideas, not vested interests, which are dangerous for good or evil.” (The quotation is usually shortened but it’s better in full.)

The Shape of The New does though have a distinctive version of the ideas that created our world. The first four chapters cover Adam Smith (morality and self-interest in political economy), Karl Marx (the desire for revolutionary redemption), Charles Darwin (embedding humanity in nature, the scientific method turned on ourselves) and the Jefferson-Hamilton debates (the nature and meaning of democracy). I knew the least about the last of these, so found it particularly interesting. The second half turns to the backlashes: the counter-Enlightenment all the way through to Fascism; and Christian and Muslim counter-reactions to modernity.

As the book concludes, the debates are still live, although of course taking new forms constantly. Those of us who hold Enlightenment values dear have to fight for them.

However, it ends with a bit of a damp squib, the conclusion being that the humanities are essential in higher education, and one of the most important aspects of study should be the history of ideas. I do happen to agree (even in economics), but it’s a rather low key ending to an ambitious and interesting book.


Economics of empire – then and now

I’ve enjoyed reading Tristram Hunt’s Ten Cities that made an Empire, out now in paperback. It’s a clever prism on British imperialism, taking a tour of major colonial cities and using a period in their history to explore the wider politics and economics of colonialism, and the cultural relations between the “mother country” and her colonies as expressed in architecture and urban design in particular.

The geographic and historical tour starts in Boston in the late 18th century (the Revolutionary War), then Bridgetown, Barbados (looking at slavery and the triangular Atlantic trade), Dublin (and the painful relationship between the two countries), Cape Town (as the base for the extension of Empire), Calcutta (early Indian adventurism by the East India Company), Hong Kong (the opium wars), Bombay (the apogee of Victorian Empire), Melbourne (and the distinctive characteristics of an Anglo-Saxon colony), New Delhi (and the independence movement) and Liverpool (where Empire ended on 22 April 1981 when Tate & Lyle closed its refinery and the docks stood empty, Tate & Lyle blaming EU membership and the change in trading patterns that involved).

The wide perspective makes very clear the commercial interests driving the politics of imperialism, from the slave trade to the exploitation of Indian cotton supplies and the market it provided for cheap Lancashire textiles, and the eastern triangular trade of Indian opium to China, Chinese luxuries to Britain and British manufactures to India. I can’t read anough about the Lancashire cotton industry for obvious reasons & have The Empire of Cotton: A New History of Global Capitalism on my wish-list.

There was also a *fabulous* In Our Time recently about the Lancashire weavers standing (at great cost to themselves) with the Union and the slaves during the American Civil War – Abraham Lincoln presented a statue to Manchester afterwards, in recognition of the support.

Modern globalization is driven just as much by drugs, arms and slavery, or people trafficking as we now call it; but these are veiled and never discussed in policy conversations, although of course the financial and professional support these trades require is big business. Nor do economists analyse it much; after all, you can’t download the data from the internet and run it through Stata. I often think we should take this illicit global economy far more seriously.

Economics meets physics – literally

By chance, two books about the intersection of economics and the physical world have landed recently here at Enlightenment Towers recently, The Remaking of the Mining Industry by David Humphreys and Power Density: A key to understanding energy sources and uses by Vaclav Smil.

I love business histories, with all their detail about how decisions get made with no reference at all to marginal cost=marginal revenue, and David Humphreys used to be chief economist of Rio Tinto and then Norislk Nickel in Russia. He knows more than probably anyone about the economics of the mining industry, so this book promises to be full of interesting nuggets (so to speak). Paging through, one of his main themes looks to be the importance of geopolitics for the industry, and the role of government in creating a stable legal framework that will enable investment with a decades-long payoff to occur. He concludes: “The world does not have a resource problem. It cannot be ruled out, however, that it may face an investment problem.”

I also like Vaclav Smil’s previous books, Made in the USA: the rise and retreat of American manufacturing and Making the Modern World: Materials and Dematerialization (well of course I’d like that one!), packed full of engineering insight. This one tells me that power density is “the rate of energy flux per unit of area” – huh? – and that moving to low power density renewable fuels will require “a profound spatial restructuring of the energy system.” My guess is that it means new transmission and distribution grids, but I’ll have to read it to be sure. The final sentence, in bold italics reads: “New energy arrangements are both inevitable and desirable, but without any doubt, if they are to be based on large scale conversions of renewable energy resources, then the societies dominated by megacities and concentrated industrial production will require a profound spatial restructuring of the energy system, a process with many major environmental and socioeconomic consequences.”

Economists behaving badly

I woke up this morning to find Roger Farmer and Noah Smith had been discussing my review of Richard Thaler’s excellent new book Misbehaving. Roger and Noah are presumably asleep now, giving me the opportunity to chip in again.

To recap, I expressed some unease about the eagerness with which economics is embracing behavioural psychology. Roger agreed, tweeting:

Here is his follow-up post on the subject. Noah replied:

@farmerrf @diane1859 @MarkThoma I already smashed the argument that behaviorism = oppression!

His Bloomberg column argues that we economists need to accept whatever the empirical evidence tells us about how people behave and using it to improve our models. The fear of Big Brother government is overdone, he argues.

My anxiety is not really about the paternalism involved in using nudges, because to govern is to be paternalistic which is why elections are vital; and of course it’s preferable to have better than worse outcomes. I’m more worried by the habit almost all economists have of thinking about policy as if society is our play pen and we are benign, omniscient deities, outside society. My sense is that the enthusiasm for behavioural “anomalies” is that it gives us new toys to play with. There is a characteristically striking Adam Curtis blog post on this tendency, which I suggest my students look at when I do the behavioural policies lecture in my course.

So my conclusion is not that we reject behavioural insights, but that we develop a more becoming humility. We pay far more attention to how the data we use are created and what they mean. We remind ourselves that “rational” is not the benchmark from which human behaviour diverges in anomalous way (cf Gerd Gigerenzer). We recall that not everyone is like us (especially as most of ‘us’ dominating economic thinking are male, white, western). We note that people change their behaviour in response to policies (as @billwells_1 pointed out in the Twitter debate, arguing it is better to inform people about the consequences of their ‘non-rational’ choices).

In short, we recognise that economics is a social science characterised by performativity, reflexivity, and great uncertainty. That’s all. (I’ve gone on about this before – anyone interested might like to look at my Tanner Lectures (pdf) and Pro Bono Economics lecture.)
