Nigeria, GDP, and all that jazz

Mine is the kind of household where we spent Sunday afternoon eagerly waiting for the announcement about the rebasing of Nigeria’s GDP, or in other words the updating of the weights on the different components that add up to GDP to reflect their share in the economy. Like a number of other African economies, it had been more than 20 years since the construction of Nigeria’s GDP statistics was last updated in this way. It happens roughly every five years in most OECD countries – the US had a significant one last year.

The announcement was worth waiting for: taking due account of sectors like films, music and mobiles took the level of GDP up by 89%, and makes Nigeria’s economy bigger in absolute terms than South Africa’s. The rebased statistics also show a marked change in the structure of the economy, as this chart from the official presentation shows.

Nothing real has changed, the economic problems like poverty and inequality and a poorly-functioning state remain, but the confidence effects on investors and entrepreneurs could be significant. Expectations are crucially important for economic decisions.

As it happens, if you want to read more about this, my [amazon_link id=”0691156794″ target=”_blank” ]GDP: A Brief But Affectionate History [/amazon_link]has a section specifically on the subject. Razia Khan of Standard Chartered, @raziakkhan, kindly tweeted key bits of it yesterday, and is a key person to follow on the subject.

Hard Times, continued

Just arrived: [amazon_link id=”0300203772″ target=”_blank” ]Hard Times: The Divisive Toll of the Economic Slump[/amazon_link], by Tom Clark with Anthony Heath. It’s the fruit of a research project that ran from 2007-2012 in the US and UK, documenting the social effects of unemployment, foreclosure, increasing inequality. The researchers asked people in certain communities to keep diaries, which are combined here with data, interviews, and more conventional academic description. It looks a good companion, albeit totally different in style, to [amazon_link id=”0571251293″ target=”_blank” ]The Unwinding[/amazon_link] (wonderful book – I reviewed it here) – although without having read this one, I wonder how the US/UK comparison will work, given how different the two countries are.

As an aside, [amazon_link id=”014143967X” target=”_blank” ]Hard Times[/amazon_link] is one of the few Charles Dickens novels I enjoyed – aversion therapy in the form of school English lessons put me off the better known ones like [amazon_link id=”1853260045″ target=”_blank” ]Great Expectations[/amazon_link]. I did much better with the ones I read myself, [amazon_link id=”B004EHZXVQ” target=”_blank” ]A Tale of Two Cities[/amazon_link] being by far his best.

A lucky escape

It was a mistake to go into Daunt Books on Cheapside yesterday when I had 20 minutes spare before lunch. In a lucky escape, I got out with only three paperbacks: [amazon_link id=”1781681678″ target=”_blank” ]Altai[/amazon_link] by Wu Ming, [amazon_link id=”0099584972″ target=”_blank” ]The Golden Egg[/amazon_link] by Donna Leon, and [amazon_link id=”0571310303″ target=”_blank” ]Geek Sublime: Writing Fiction, Coding Software[/amazon_link] by Vikram Chandra. The blurb asks: Can code ever be called beautiful? It promises the book looks at the links between logic gates and modernism, geeks and machismo, and Indians and coding. Irresistible.

Capital in the 19th century

During the mid-late 1970s era of high inflation, I was a teenager growing up in a household with two parents who worked, but not in jobs with unions that could deliver inflation-beating wage increases, and whose small savings were held in a building society account. Rising food and energy prices made things tough. Marked as we all our by personal experience, I’ve ever since believed inflation to be harmful for people on relatively low incomes, tending to mean declining real earnings and negative returns on savings.

The early section of Piketty’s [amazon_link id=”067443000X” target=”_blank” ]Capital in the 21st Century[/amazon_link] has given me pause for thought. He contrasts the Victorian and Edwardian era of stable prices and rentier wealth (in the form of land and then government bonds) with the post-1920s era of declining importance in inherited wealth. He writes:

“Capital is never quiet: it is always risk-oriented and entrepreneurial, at least at its inception, yet it always tends to transform itself into rents as it accumulates in large enough amounts.” (p115-116)

The point of accumulation is to build up enough to stop working, whether at the scale of a character in an Austen or [amazon_link id=”0140440178″ target=”_blank” ]Balzac novel[/amazon_link], or at the scale of a colonial power like France or Britain.

What changed with the onset of the violent 20th century was inflation. In the 19th century, when governments built up war debts, rentier classes bought the government bonds and could live securely on the repayments. “In the 20th century, a totally different view of public debt emerged, based on the conviction that debt could serve as an instrument of policy aimed at raising public spending and redistributing wealth for the benefit of the least well-off members of society. The difference between these two views is fairly simple: in the 19th century, lenders were handsomely reimbursed, thereby increasing private wealth; in the 20th century, debt was drowned by inflation and repaid with money of decreasing value.” (p132)

France inflated far more dramatically than the UK in the period 1913-1950, and French public debt dropped from 80% to 30% of national income over that period. The UK had a colossal 200% of GDP debt in 1950, but made up for it with inflation in the 1950s and especially the 1970s. In both cases, though, inflation was the means of expropriating the rentier classes and, Piketty argues, one of the key reasons the 20th century bucked the tendency of capitalism to create and enhance entrenched wealth inequality. So this is obviously a different perspective on inflation from my teenage perception.

I was chatting about this to Professor Dieter Helm, who chairs the UK’s Natural Capital Committee and is writing a book about valuing natural capital (which will be a must-read when it’s out). He pointed out that the shift towards an inflationary regime coincided with a generational rebellion against the Victorian emphasis on thrift and investment for the future, in favour of consumption and the present. In Britain, the Bloomsbury Group – including Keynes – exemplified this; see for example Michael Holroyd’s tome on [amazon_link id=”0099332914″ target=”_blank” ]Lytton Strachey[/amazon_link].

This all makes one wonder about the next few decades – I’d bet on a return to inflation and expropriation of the bond-holding classes (pensioners?), even though the pressing concern is deflation. But this is a bet, not a forecast. Besides, the future the Victorians built is the one we’re still living off, the infrastructure and institutions. Anybody who cares about sustainability (in its broadest sense) must surely be thinking in terms of tilting the balance away from consumption and towards investment. Towards capital, in fact, which makes its distribution all the more important.

Capital, statistics and stories

Two hundred pages into Piketty’s [amazon_link id=”067443000X” target=”_blank” ]Capital in the 21st Century[/amazon_link], I’ve found plenty of interest but am not yet bowled over as some reviewers have been. Still, 400 pages to go. I’m not going to live tweet the reading experience but will pick up on some interesting points as I go along before perhaps attempting an overall review.

[amazon_image id=”067443000X” link=”true” target=”_blank” size=”medium” ]Capital in the Twenty-First Century[/amazon_image]

A mere 58 pages in, I was calling out ‘hear, hear’ when I read this:

“One conclusion stands out in this brief history of national accounting: national accounts are a social construct in perpetual evolution. They always reflect the preoccupations of the era in which they were conceived. We should be careful not to make a fetish of the published figures.”

This is needless to say completely in harmony with my own view in [amazon_link id=”0691156794″ target=”_blank” ]GDP: A Brief But Affectionate History[/amazon_link].

[amazon_image id=”0691156794″ link=”true” target=”_blank” size=”medium” ]GDP: A Brief but Affectionate History[/amazon_image]

Too many economists pay no attention to the figures they are using, simply downloading time series from handy databases and telling stories around them. This chart showing ONS revisions to 1990s UK GDP data (or something similar) should be pinned above every economist’s desk as a reminder that the figures, although they’re all we have to measure the tide of economic events, are as broad brush as can be. The late 80s boom was even boomier than we remember, but the subsequent bust far less severe. As a reminder, there were a few things happening in 1992 – a general election in April, double digit interest rates in the summer, ‘Black Wednesday’ in September.

The present national accounts – as I describe in my book – co-evolved with Keynesian macroeconomics. The accounting identity C+I+G+(X-M) segued into the theory of aggregate demand and its successors. We’re stuck with GDP until the next Keynes conceives a theory of aggregate dynamics fit for a largely intangible, service and information driven economy, when there will have to be a different statistical framework.

PS I should add that it was @BenChu_ who alerted me to the 1990s revisions
