Back in September 2012, I wrote a post on whether capitalism is a
mode of production that just suffers a series of crises, booms or
slumps, or is instead (or also) a system that will eventually break down
and collapse when it passes it ‘use-by’ date. I think I still hold to
my tentative conclusions in that post (http://thenextrecession.wordpress.com/2012/09/12/crisis-or-breakdown/). In that post, I referred to a paper by Robert J Gordon, a professor at North-Western University entitled, Is US economic growth over? – see http://www.nber.org/papers/w18315 and http://www.voxeu.org/article/us-economic-growth-over.
In that paper Gordon argued that the rapid technological progress
under the capitalist mode of production in the last 250 years is now
over. Growth in real GDP per capita, at least in the US economy, will
be slower that in any extended period since the Civil War. Gordon
argued there are six headwinds that will slow future innovation: an
ageing population in the mature economies; rising inequality; an
increasing lack of competitive advantage for the mature capitalist
economies; poorer education because public investment in education is
being destroyed; increasing environmental regulations; and excessive
debt. Gordon concluded that US real economic growth could fall to just
an average 0.2% a year for the foreseeable future compared 2-3% of the
past.
Whether those headwinds justify such slower economic growth is open
to question. Gordon suggested that capitalism drove the productive
forces (and thus economic growth) upwards from about 1750 to 1950. But
since then it has been in a downward spiral that no longer takes the
productive forces forward. Capitalism, at least in the mature economies,
has had its day.
Well, Gordon’s paper came in for a lot of flack from mainstream
economics. The arguments against Gordon centred round his claim that
technological progress had come to an end. Both arch Keynesian guru,
Paul Krugman and arch Chicago neoclassical economist John Cochrane
agreed that their “gut feeling” was that Gordon is too pessimistic about the future of technology. As Gordon put it in a sequel paper to his 2012, just released (Gordon 050314), “A
controversy about the future of U.S. economic growth was ignited by my
paper released in late summer 2012.1 The debate began with my prediction
that over some indefinite period of time into the future, perhaps 25 to
40 years, the growth of real per-capita disposable income of the bottom
99% of the U.S. income distribution would average 0.2% per year,
compared to 2.0% per year in the century before 2007. This prediction
set off a firestorm of controversy with commentary, blogs, and op-eds
around the world.”
Gordon admitted that he was talking about the US and no other economies where the ‘headwinds’ may be less and agreed that “there is plenty of room for “catch-up growth” in the emerging markets of the world”. And he was looking at potential growth not actual real GDP.
Gordon was criticised for underestimating the new technologies that
will come into play in driving up productivity growth over the next few
decades. In his sequel paper, he says “the primary role of the
headwinds in predicting slow future growth escaped notice in the initial
round of controversy about innovation” He retorts: “there is no
need to forecast that innovation in the future will “falter,” because
the slowdown in the rate of productivity growth over the past 120 years
already occurred more than four decades ago. This sequel paper explains
why the pace of innovation declined after 1972. The future forecast
assumes that innovations in the next 40 years will be developed at the
same pace as the last four decades, but reasons for scepticism are
provided for that prediction.”
So Gordon claims that he does not need to predict poor innovation
from here still to conclude that US economic growth is set to slow to a
trickle over the next few decades. Gavyn Davies, the Keynesian
economist and former chief economist at Goldman Sachs, who now blogs for
the Financial Times, agreed that the prospects for increased living
standards for the average American household do not look good (The
economic future of Americans – some arithmetic, http://blogs.ft.com/gavyndavies/2014/03/02/the-economic-future-of-americans-some-arithm).
Gordon predicts the real living standards of all but the top 1% in
the income distribution will barely grow at all in the decades ahead and
that this experience of the vast bulk of the population has been no
better than that since 1973. Over the whole of that period, median real
household income has actually risen by only 0.1% per annum.
However, Davies’ successor at Goldman Sachs, Jan Hatzius, is less
pessimistic. Hatzius points out that the trend in college attendance
continues to expand strongly, so he does not see why the contribution of
education to productivity growth should decline. Hatzius also reckons
that the rise in the profits share cannot continue indefinitely, and
cites evidence that the share of the top 1% in the wage distribution
stopped rising in 1997. He therefore reckons that rising inequality will
be much less of a factor in the decades ahead. Even so, as Davies
points out, the resulting future growth in median household income is
still only 1-1.5%. This is what US capitalism offers most Americans at
best, and that assumes no more major recessions or slumps.
But is technology and innovation really going to fail to deliver
better growth over the next few decades? The rise of robots and
artificial intelligence is predicted by some to have an exponential
effect in what has been called the ‘second machine age’ in Andrew McAfee and Erik Brynjolfsson’s influential book on the march of the robots. I intend to return to this issue in a future post.
But what cannot be denied is the productivity growth in the US and
other major capitalist economies has been slowing since the 1970s –
neoliberalism has failed to innovate. US output per hour of work since
1972 has risen by only about 1.3% a year, apart from the brief dot.com
boom in the late 1990s. And real output growth per worker has slowed
from a mediocre 2.4% a year (as Gordon recorded) in the last 20 years to
just 1% a year over the past three years.
Many critics of Gordon’s view argue that this slowdown is temporary
and is caused by the effects of the Great Recession and the cyclically
weak recovery since. Once capitalists start to invest more,
productivity growth will recover to the previous trend. The only
problem with that argument is that there is still little sign of any
significant return to the previous trend in business investment growth.
I did a quick analysis of US business investment growth. In 2013,
real spending on business investment in the US rose 3.8%, little more
than half the rate achieved prior to Great Recession. And what is
especially noticeable is that spending on hi-tech innovatory equipment,
the previously dynamic high growth sector with an average of 10-20%
annual growth, is very weak, now growing at a pace slower than overall
real GDP.
Hi-tech spending on both equipment and software has fallen as a share
from 4.7% of US GDP in 2000 to 3.5% in 2013. It is this area that is
key to boosting productivity. What is the reason for this slowdown in
investment in new technology? Well it appears to be that the cost of
new equipment and software is just too high relative to the realised and
expected return on those investments – in other words, the rate of
profit is not high enough.
Kenneth Rogoff, of Reinhart and Rogoff fame (or infamy, see my post, http://thenextrecession.wordpress.com/2013/04/17/revising-the-two-rrs/), pitched in on Gordon’s predictions in a recent article (Malthus, Marx, and Modern Growth).
He agreed that there were obstacles to continuing the ‘previous
success’ of capitalism. There was environmental degradation; growing
inequality within countries; aging populations that don’t work; and the
risk of financial crashes. Yet he remained optimistic that capitalism
can overcome these challenges. After all, “so far, every prediction
in the modern era that mankind’s lot will worsen, from Thomas Malthus to
Karl Marx, has turned out to be spectacularly wrong… despite a
disconcerting fall in labour’s share of income in recent decades, the
long-run picture still defies Marx’s prediction that capitalism would
prove immiserating for workers. Living standards around the world
continue to rise.”
Rogoff continues that technological progress has trumped obstacles to economic growth in the past. “Will
each future generation continue to enjoy a better quality of life than
its immediate predecessor? In developing countries that have not yet
reached the technological frontier, the answer is almost certainly yes.
In advanced economies, though the answer should still be yes, the
challenges are becoming formidable.” So the mainstream economists
remain broadly optimistic about the future of capitalism, despite
Gordon’s prognostications – not surprisingly.
In my post in September 2012, I reckoned that capitalism could get a
further kick forward from exploiting the hundreds of millions coming
into the labour forces of Asia, South America and the Middle East? This
would be a classic way of compensating for the falling rate of profit
in the mature capitalist economies. I have calculated before that the
world rate of profit (not just the rate of profit in the mature G7
economies) stopped rising in the late 1990s and has not recovered to the
level of the golden age for capitalism in the 1960s, despite the
massive potential global labour force. It seems that even the
countervailing factors of foreign investment in the emerging world,
combined with new technology, have not been sufficient to keep pushing
up the world rate of profit, so far (see roberts_michael-a_world_rate_of_profit.).
I’ll be revisiting these measurements of the world rate of profit in a
future post in the light of new work done by a young Marxist economist
from Argentina.
Yes, crises are endogenous to capitalism because of the main
contradiction within the capitalist mode of production, of accumulation
for profit and not need. But also it is possible for capitalism to
recover and soldier on ‘endogenously’ when sufficient old capital is
destroyed in value (and sometimes physically) to allow for a new period
of rising profitability. Capitalism can only be replaced by a new
system of social organisation through conscious action of human beings,
in particular by the majority class of people (the working class
globally). Without such conscious action, capitalism can stumble on.
Maybe the mainstream economists will be proved right and the new
technology in the pipeline will be applied by a resurgent capitalist
revival to boost productivity and growth, but Gordon’s evidence suggests
otherwise.
