The Post-Growth Challenge — Secular Stagnation, Inequality and the Limits to Growth | CUSP Working Paper No 12

Abstract

Critics have long questioned the feasibility (and desirability) of exponential growth on a finite planet. More recently, mainstream economists have begun to suggest some ‘secular’ limits to growth. Sluggish recovery in the wake of the financial crisis has revived discussion of a ‘secular stagnation’ in advanced economies, in particular. Declining growth rates have in their turn been identified as instrumental in increased inequality and the rise of political populism. This paper explores these emerging arguments paying a particular attention to the dynamics of secular stagnation. It explores the underlying phenomenon of declining labour productivity growth and unpacks the close relationships between productivity growth, the wage rate and social inequality. It also points to the historical congruence (and potential causal links) between declining productivity growth and resource bottlenecks. Contrary to some mainstream views, this paper finds no inevitability in the rising inequality that has haunted advanced economies in recent decades, suggesting instead that it lies in the pursuit of growth at all costs, even in the face of challenging fundamentals. This strategy has hindered technological innovation, reinforced inequality and exacerbated financial instability. At the very least, this paper argues, it is now time for policy to consider seriously the possibility that low growth rates might be ‘the new normal’ and to address carefully the ‘post-growth challenge’ this poses.

Abstract
Critics have long questioned the feasibility (and desirability) of exponential
growth on a finite planet. More recently, mainstream economists have
begun to suggest some ‘secular’ limits to growth. Sluggish recovery in the
wake of the financial crisis has revived discussion of a ‘secular stagnation’
in advanced economies, in particular. Declining growth rates have in their
turn been identified as instrumental in increased inequality and the rise of
political populism. This paper explores these emerging arguments paying a
particular attention to the dynamics of secular stagnation. It explores the
underlying phenomenon of declining labour productivity growth and
unpacks the close relationships between productivity growth, the wage rate
and social inequality. It also points to the historical congruence (and
potential causal links) between declining productivity growth and resource
bottlenecks. Contrary to some mainstream views, this paper finds no
inevitability in the rising inequality that has haunted advanced economies
in recent decades, suggesting instead that it lies in the pursuit of growth at
all costs, even in the face of challenging fundamentals. This strategy has
hindered technological innovation, reinforced inequality and exacerbated
financial instability. At the very least, this paper argues, it is now time for
policy to consider seriously the possibility that low growth rates might be
‘the new normal’ and to address carefully the ‘post-growth challenge’ this
poses.

‘[The GDP] measures everything… except that which makes life
worthwhile.’
Robert Kennedy, 1968
1 Introduction
The pursuit of economic growth has been a defining feature of the global
economy for well over half a century.
1
Growth narratives are evident in every
sphere: economic, secular, social and political. Indeed, their prevalence and
centrality in political discourse is so pronounced that it is credible to speak
of something like a ‘growth fetish’
2
– a predominant, often unquestioned
assumption that economic expansion is an irreducible good without which
social progress is impossible.
Critics of this view also have a long pedigree. Robert Kennedy’s speech at
the University of Kansas in March 1968, fifty years ago this year, remains
both resonant and prescient of the ensuing critique. The publication of the
Club of Rome’s Limits to Growth report four years later established the
resource and environmental parameters of the growth critique. Their
analysis too has stood the test of time.
3
Political responses to the Club of Rome were striking. Politicians of almost
every hue stood up to repudiate the report. US President Ronald Reagan saw
fit to insist on several occasions that there are ‘no limits to economic growth,
because there are no limits to human ingenuity’,
4
an argument which owes
more to rhetoric than to logic. But the economist Kenneth Boulding, giving
evidence to a US House of Representatives Select Committee hearing in 1973
responded differently. ‘Anyone who believes that exponential growth can
continue indefinitely on a finite planet,’ he remarked, ‘is either a madman
or an economist’.
5
The final decades of the twentieth century saw the central issue largely
relegated to questions about the speed and efficiency with which it would
be possible to ‘decouple’ economic growth from its material impacts and
thereby avoid the need to transform the economic system itself. Ecological

modernisation (later eco-modernism) prevailed as the politically acceptable
face of ecological concern
6
and the deeper critique was kept alive largely
through marginal voices such as those of economists such as Herman Daly,
Marilyn Waring and Richard Douthwaite, supported at times by a parallel
argument about the social limits to growth.
7
In the decade that has passed since the financial crisis of 2008 however,
there has been a resurgence of interest in the growth critique from a variety
of different perspectives.
8
A deeper recognition of the environmental and
social limits to growth has certainly played some part in this more recent
debate. But a fascinating new dimension has arisen. As economic
uncertainty continues to haunt the most developed countries, some
mainstream economists were prepared to flirt with the idea that lower
growth rates were not simply a temporary or cyclical phenomenon in the
wake of the crisis.
The term ‘secular stagnation’ – first coined in the 1930s – was revived to
describe a decline in the rate of economic growth in advanced nations that
appears to be only partly to do with the financial conditions of 2008 and to
have its roots in factors that predate the crisis by several decades at least. As
the futurist Martin Ford has suggested, there are ‘good reasons to believe
that the economic goldilocks period has come to an end for many developed
nations.’ Low and perhaps declining growth rates may be here to stay.
One of the aims of this paper is to explore both the causes and the potential
implications of such a slowdown. Section 2 discusses the evidence both for
the slowdown and for its historical development over time. Section 3
explores one particular aspect of this dynamic, namely the puzzle of
declining productivity growth, and speculates on the link between this
phenomenon and the declining energy return on energy investment. Section
4 elaborates on some of the most important impacts of the decline,
particularly in terms of rising income and wealth inequalities.
Finally, Section 5 draws together the threads of the analysis together to
propose a novel interpretation of recent ‘crises of capitalism’. Specifically, I
argue that rising inequality and the resulting political instability are neither
the accidental aftermath of the financial crisis nor the inevitable result of

declining growth rates, but rather the consequence of continuing to cling to
the ‘growth fetish’ at a time when economic (and resource) fundamentals
are operating in the wrong direction. The ‘post-growth’ challenge of the
paper’s title is not so much about trying to ‘turn growth down’ but rather
about protecting social progress in the face of what some well-known
economists are now prepared to call the ‘new normal’.

2 Secular Limits to Growth
In November 2013, five years after the collapse of Lehman Brothers, the
former World Bank chief economist and US Treasury Secretary Larry
Summers gave a speech to the International Monetary Fund’s annual
research conference which sent something of a shock wave through the
audience. He suggested that the slow growth rates and continuing
uncertainties of the post-crisis years were not just temporary after-effects
of the financial crisis itself. ‘The underlying problem may be there forever,’
he said.
10
Summers was certainly not the only, or the first, economist to make such a
claim.
11
But he was certainly the most well-known economist to do so. The
repercussions were profound. It suddenly became acceptable to ask
previously unthinkable questions. What if there just wasn’t so much growth
to be had anymore? What if sluggish demand was not just a cyclical
downturn but a deeper reluctance on the part of business to invest and of
consumers to spend, a more entrenched change in economic fundamentals?
Could an era of lower growth rates (Figure 1) be the ‘new normal’?
12
Not everyone agreed that the slowdown was a result of sluggish demand.
Some argued that the problem was one of supply. US economist, Robert
Gordon suggested that a slowdown in the rate of economic growth is the
result of a decline in the pace of innovation – many of the big technological
advances of the last two centuries are now over – together with six
‘deflationary headwinds’ which are taken to include: an aging population,
rising inequality, and the ‘overhang’ of consumer and government debt.

economic fundamentals pointed to serious problems for the growth paradigm.

14
Both the supply-side and the demand-side explanations are interesting from
the perspective of this paper. Ecological economists have argued for some
time that the enormous growth in productivity of advanced economies was
only possible at all because of the abundance of high-quality fossil energy
sources.
15
Any slowing down in the availability or quality of such sources
might be expected, as the Club of Rome suggested back in 1972, to slow
down overall productivity and reduce industrial output. Is it possible that
the slowing down in supply highlighted by Gordon and others is a direct
consequence of these dynamics?
The demand side explanation is more attuned to the possibility that there
are social limits to growth. The existence of diminishing returns to income
could certainly play a role in the stagnation of demand. In fact, one partial
explanation for Japan’s ‘lost decades’ has been that the nation experienced
a saturation in consumer demand from an ageing population more inclined

The Hodrick-Prescott (HP) filter is a statistical tool used to remove the cyclical component of
macroeconomics data and expose the underlying long-term trend. See for example:

chosen for this analysis is typical for time series data with an annual frequency. Note that the
linear trend associated with the HP filter is the same as the linear trend associated with the
underlying data.

to save than to spend. Is it conceivable that social dynamics are now
contributing to a demand-side secular stagnation in the advanced
economies? Could this already be having a knock-on impact on the global
economy?
Economists are divided on whether the slow-down is a result of demand or
supply-side forces. Jean-Baptiste Say once argued that ‘supply creates its
own demand’ because making things provides people with income which
they must then spend back into the economy. If this were really the case,
then as long as the supply potential of the economy continues to grow, there
should be no bottlenecks on growth. One of John Maynard Keynes’
contributions to economics was to show how this could go wrong, once the
demand for money and financial assets came into the picture. If people
hoarded money or used it to buy (or speculate in) financial assets, then
incomes never find their way back in as demand.
In his response to those arguing that the problem was with supply rather
than demand, Summers invoked a kind of ‘inverse Say’s Law’: namely, that
a lack of demand could itself create a lack of supply. For reasons similar to
those highlighted by Keynes, he argued that a slowdown in demand,
combined with increasing investment in financial assets would divert
funding away from productive investment, thus diminishing the supply
potential of the economy. Perhaps most pertinently, he pointed out that
creating more and more cheap money (through low interest rates and
quantitative easing) could not solve this problem, because cheap money
only encourages speculative lending.
16
An even more pressing argument, which I return to in the following section,
is that this process of cheap money and increasing speculation tends to
inflate asset prices and increase inequality. There have been suggestions
that inequality itself has a tendency to suppress growth, partly because
richer people have a lower propensity to consume. This accelerates the
money hoarding process, increases inequality again and suppressing growth
further.
17
Whatever the balance between supply and demand side factors, the global
implications of a ‘secular stagnation’ are now beginning to become clear.
The trend rate of growth in the global GDP was 5.5% in 1966; by 2016 it was
little more than 2.5% (Figure 1). The highest global growth rate in the last
half a century occurred in the year 1973: ironically, the year of the first oil

crisis. By the time of the second oil crisis in 1979, the trend growth rate had
fallen to a little over 3%, during which oil prices had effectively quadrupled,
after several decades of stability.

price point: pre-1984 – Arabian Light; post-1984 – Brent Crude
It is plausible that the two successive crises had something at least to do
with a subsequent suppression of the growth rate. By 1980, the price of oil
(Figure 2) had reached the equivalent of $100/bbl (measured in today’s
money). Conventional wisdom would certainly suggest that such price rises
would have a profound impact on economic growth by increasing the costs
of business and depressing people’s real spending power. The global
slowdowns in 1974/5 and 1981/2 are usually attributed to the oil price
shocks.
Conventional economics suggests that any real decline in resource quality
should be visible in rising prices in the economy, allowing markets to
respond efficiently by developing substitutes. What is clear from the history
of the last few decades (Figure 2) is that this relationship is much more
complex (and volatile) in practice than theory suggests. Substantial price
rises did indeed accompany the oil crises. But in the years following the two

crises, there was a lengthy decline in oil prices which lasted right through to
the end of the 1990s. By 1998, the oil price had fallen to less than $20 (in
2016 prices), lower than it had been for a quarter of a century. During that
time (Figure 1), the decline in the growth rate had certainly stabilised.
Indeed, the trend global growth rate had actually increased slightly.
At this point, it is useful to introduce the question of government policy,
which clearly had some impact both on oil prices and on growth rates in the
aftermath of the oil crises and in the run up to the financial crisis. In
particular, it’s useful to identify two very distinct approaches, associated
with contrasting schools of economic thought: Keynesianism on the one
hand, and monetarism on the other.
Developed in response to the Great Depression in the 1930’s, John Maynard
Keynes macroeconomics saw a critical role for government in maintaining
economic stability. If supply potential was not enough to keep growth going
(as Says had argued), governments could not rely on households and firms
simply to go on spending during the hard times. They must play an active
role in stimulating the economy to ‘kick-start’ growth again. The strategy
worked, up to a point, in the wake of the Depression. It was exemplified in
particular by Franklin D Roosevelt’s ‘New Deal’ in the States.
The initial response to the slowing down of growth rates in the aftermath of
the first oil crisis was Keynesian. Governments attempted to spend their way
out of the ensuing recession. The problem was that economic fundamentals
were working against this policy. It was not a reduction in demand, per se,
that was standing in the way of growth and leading to unemployment, but
rather a reduction in real spending power caused by higher prices, resulting
in particular from the high price of oil. Having government attempt to
stimulate demand further was (momentarily at least) having the perverse
impact of simply pushing up prices even further leading to high levels of
inflation, with no reduction in unemployment.
Faced with this situation, governments abandoned Keynes and turned
instead to monetarism – the brainchild of Chicago school economist Milton
Friedman. Built on a neo-liberal philosophy with a strong belief in the free
market as the best regulator of human affairs, monetarism had no truck with
fiscal stimulus (or indeed with government intervention generally) and
argued instead that the route out of low growth was to reduce the cost of
money, so that firms would more easily invest in the productive capacity of
the economy and households could fund any temporary constraints on
spending through debt. These mechanisms for financial liquidity would free

up the economy to grow again, allowing prices to fall and employment to
bounce back.
The growth rate did recover slightly over the next two decades. Or at the
very least, the decline in the global growth rate appears to have been halted.
It is not unreasonable to suggest that this stabilisation was in part a
consequence of looser monetary policy in the advanced economies during
the 1980s and early 1990s.
So when oil prices started to rise again following the attack on the Twin
Towers in September 2001 and rising political instability in the Middle East,
governments once again thought they knew what to do. A burst of increased
liquidity had ‘saved’ the global economy from the crises of the mid-1970s.
The thing to do was to continue to ensure that money was available for
investors to invest and for households to spend. Governments around the
world ushered in a period of cheaper money: a significant decline in the
interest rate, a loosening of financial regulation, an unprecedented degree
of financial innovation.
There are several lessons from all this. One of them is that the interaction
of political instability, government policy and supply-side constraint is
capable of masking entirely the simple relationship between price and
resource quality. It’s almost impossible for the market to detect what’s
going on in terms of resource quality from the visible signal of prices on the
market. A second lesson is the potentially damaging impact of volatile prices
on the real economy. Though not in itself a signal of underlying scarcity an
oil price of $147 a barrel – reached in July 2008 – was certainly instrumental
in creating uncertain global economic conditions, even if it wasn’t the
immediate trigger for the financial crisis.
Perhaps even more important are the effects of government policy on the
stability of the financial system. The policies pursued in the wake of the oil
crisis, designed to keep the growth rate going, irrespective of underlying
fundamentals, were complicit in generating an increasing fragility in
financial markets. Loose monetary policy facilitated a continued reduction
in public debt burdens, but the effect was in part at least simply to transfer
this debt to the private sector. While interest rates were low and debt
burdens were not too high, this didn’t seem to matter much. But as more
and more households accumulated more and more debt, the conditions for
instability were accumulating.

10 | CUSP WORKING PAPER No. 12
By the early 2000s, firms, banks and households had become ‘overleveraged’
(Figure 3). The policy response was to pump more and more money into the
system by lowering interest rates further and relaxing financial regulations.
All it needed was a change in the rate of defaults on ‘subprime’ loans and
the bubble would have to burst. This was the era of ‘easy money’, the ‘age of
irresponsibility’ as then Prime Minister Gordon Brown called it, and it led
inexorably to the financial crisis.

‘The question then arises,’ wrote Summers in 2014, ‘can we identify any
stretch during which the economy grew satisfactorily under conditions that
were financial sustainable?.’
20
His answer, and indeed the answer of a
number of other economists, was: no. Chasing growth through loose
monetary policy in the face of challenging underlying fundamentals had led
to financial bubbles which destabilised finance and culminated in crisis.

11 | CUSP WORKING PAPER No. 12
One of the key lessons from Figure 3 is the steep rise in public debt following
the collapse of Lehman Brothers. In the wake of the crisis, western
governments committed trillions of dollars to securitise risky assets,
underwrite threatened savings, recapitalise failing banks and re-stimulate
the economy in the wake of the crisis.
No one pretended this was anything other than a short-term solution. Many
even accepted that it was potentially regressive: a temporary fix that
rewarded those responsible for the crisis at the expense of the taxpayer. But
it was excused on the grounds that the alternative was simply unthinkable.
Collapse of the financial markets would have led to a massive and
completely unpredictable global meltdown. Entire nations would have been
bankrupted. Commerce would have failed en masse. The humanitarian costs
of failing to save the banking system would have been enormous.
But government bailouts precipitated further crises. Country after country,
particularly across the Eurozone, found themselves negotiating rising
deficits, unwieldy sovereign debt and down-graded credit ratings.
21
Austerity policies, brought in to control deficits and protect ratings, failed
to solve the underlying issues. Worse, they created new social problems of
their own.
The withdrawal of social investment caused rising inequality, deepening
unemployment, worsening health outcomes and an increasingly agitated
public. The injustice of bailing out the architects of the crisis at the expense
of its victims has become plain for all to see. To this day, growth rates have
not yet returned to those of the pre-crisis era, let alone to those that
characterised the mid 1960s, and the conditions for wider social and political
unrest remain palpable.
22
3 The Productivity Puzzle
Up to this point, I have presented the story of economic growth over the last
half century almost as though it were a single global phenomenon. Clearly,
it isn’t. There are signficant differences in particular between the more
advanced economies and the emerging market and developing economy
21

countries. Furthermore, these differences have themselves changed over
time.
Figure 4: Growth Rate in OECD GDP per capita: 1966 – 2016
Source: Author’s calculations from World Development Indicators Database (WB 2017); moving
trend calculated using HP Filter with lamda = 100.
In the mid-1960s, growth in the global economy was dominated by the
advanced nations, where the growth rate in per capita GDP was at least half
a percentage point higher than the global average and almost five
percentage points higher than growth in the developing economies. By the
time of the financial crisis that had already changed. Some of the poorest
economies in parts of sub-Saharan Africa and South East Asia still had per
capita growth rates below 1% per annum. But growth rates in the emerging
markets (China, India, Brazil, for instance) had long since overtaken growth
rates in the OECD nations. In the advanced economies, meanwhile, per
capita growth had fallen substantially from its mid 1960s peak of around 4%
to something closer to 1% per annum (Figure 4).
The significance of this fall is perhaps best captured by extrapolating
forwards to the point at which the growth rate reaches zero. Whereas for the
global GDP per capita (Figure 1), the point at which growth disappeares is
more than 60 years into the future, for GDP per capita in the OECD nations,
the point is brought forwards dramatically. In less than a decade, on current

trends, there would be no growth at all in GDP per capita across the OECD
nations.

with lamda = 100. Extrapolation of the linear trend suggest that labour productivity growth
reaches zero by 2028.)
A part of the reason for the steepness of this fall, of course, is the severe
recession during and after the financial crisis, which was deeper for the
OECD nations than it was for other parts of the world. In fact, the moving
trend appears to show a pronounced upturn since that time, indicating
perhaps that the OECD nations are able to ‘turn the corner’ and achieve
higher growth levels again. A closer look at the reasons for this upturn,
however, suggests caution in interpreting the trend in this way.
Figure 5 shows the year-on-year growth in labour productivity – defined as
the GDP produced per hour worked on average across the economy. Though
labour productivity growth starts out in more or less the same place as the
growth in GDP per capita at the start of the period, the speed of decline is
noticeably faster, there is no partial recovery in the aftermath of the second
oil crisis and there is nothing in the way of an upturn during the final years.
Labour productivity was growing at only 0.7% per year in 2016, significantly
slower than the growth in GDP per capita.

These differences between the GDP per capita growth and the underlying
labour productivity growth have important implications. Labour
productivity is defined here as the GDP generated (on average) by each hour
of labour worked in the economy, that is the GDP divided by the total hours
worked in the economy. The total hours worked in the economy can be
characterised as the average hours worked by each person in the workforce
multiplied by the number of people in the workforce. The number of people
in the workforce can also be written as the population multiplied by a
‘workforce participation rate’.
A little mathematics reveals that the GDP per capita is equal to the labour
productivity multiplied both by the workforce participation rate and the
average number of hours worked by each member of the workforce. If the
workforce participation rate and the average hours worked were to remain
constant, the GDP per capita would be directly proportional to the labour
productivity.
23
In this case, the growth rate in GDP per capita would always
be equal to the growth rate in labour productivity. It is evident from Figures
4 and 5 that this is not the case.
Specifically, growth in labour productivity has declined faster than growth
in the GDP. Mathematically, this means either that the workforce
participation rate has risen over time or else that the average number of
hours worked by each worker in the economy is increasing. In fact, both of
these things have happened at different times during the last half a century
or so. Until recently, the average hours worked had been declining across
most the OECD but participation rates had increased, allowing the growth
rate in GDP per capita to decline more slowly than the decline in labour
productivity growth. Since the financial crisis, there has been an increase in
the average hours worked across many advanced economies, including the
UK and the US. People are working longer hours in order to sustain their
desired income levels.
24
The broad point is that the rate of labour productivity growth tells us
something fundamental about the capacity of the economy to deliver
income growth. It is central to our understanding of how hard people have
to work in order to sustain a given income level. Specifically, when labour
productivity growth across the economy declines faster than the growth in
23
If lp is labour productivity, N is the workforce, P is the population, n = N/P is the workforce
participation rate and h is the number of hours worked on average by each member of the work
force, then it follows first that GDP = lp * h * N and therefore that GDP per capita = GDP/P = (lp * h
* N)/P = lp * h * n. W hen h and n are constant, GDP is directly proportional to lp.

average income, it means that people on average must work longer hours for
that income. Figure 5 suggests that, on current trends, labour productivity
growth will decline to zero across the OECD by around 2028. In about a
decade, it is entirely possible that per capita GDP growth could only be
achieved by having a greater proportion of the population in the workforce
or by having people work on average for longer hours.
This finding is particularly puzzling in the face of a completely opposite
proposal, namely that advances in technology (specifically, in artificial
intelligence and robotisation) are poised to make such massive increases in
labour productivity that vast swathes of the current workforce, far from
being asked to work for longer, will find themselves redundant because there
is no longer enough work for human beings to do. The jury is still out on
where (in which sectors) this displacement is most likely to occur, when it is
likely to arrive and the extent to which it will be a good or a bad thing for
the economy as a whole. The most puzzling question is why it is not already
visible in the labour productivity statistics.

this case the UK – for which a long time-series on labour productivity exists.
The UK was the first country to industrialise, it typifies the structure of late-
modern western economies, and may well be facing the challenges of post-
industrialism sooner than other OECD countries. Understanding the trend
in labour productivity growth in the UK therefore offers a useful starting
point to understanding the challenges to the future of economic growth
more widely.
Figure 6 shows the trend in labour productivity growth in the UK since the
beginning of the 20th Century. It is an extraordinary story. Broadly speaking,
trend labour productivity growth rose more or less continually from the
beginning of the century until about the mid-1960s, aside from ups and
downs related to the two world wars and the Great Depression. Since the
mid-1960s however, with virtually no remission at all, the trend in labour
productivity growth has been falling. This fall was at best slowed down, but
never entirely reversed by the introduction of extraordinary new
technologies such as personal computing, electronic communications and
the internet.
The period between the second oil crisis and the collapse of the dotcom
bubble at the turn of the millennium witnessed a kind of plateau in labour
productivity growth. Certainly the decline was not so fast during these years.
But since 9/11, labour productivity growth in the UK has dropped
precipitously. It’s particularly important to recognise that this decline
preceded the financial crisis itself by at least a decade (from the post oil
crisis plateau) and more likely by several decades. By 2016, the trend labour
productivity growth rate in the UK was just 0.12%, lower than at any point
in more than a century.
Again, to be clear, the only way to squeeze economic growth out of an
economy with virtually no productivity growth at all is to have a higher
workforce participation or to have people working longer hours. The clear
rise and fall of the trend therefore carries some important lessons about the
development of modern society, the potential for income growth and the
relationship to people’s work-life balance and standard of living.
It may also have some bearing on the discussion in preceding sections. There
is no common agreement as to the causes of the pattern shown in Figure 6.
The suggestion that the rise and fall of productivity growth is associated
with the availability of physical resources such as energy and minerals is
clearly one that merits further attention. The similarity between the rise and

17 | CUSP WORKING PAPER No. 12
fall in labour productivity shown in Figure 6 and some recent studies of the
energy return on energy invested (EROI) in fossil fuels is striking.
Figure 7: Energy Return on Energy Investment in Canada: 1945 – 2009
Source: Author’s working using data from Friese 2011
Figure 7 shows the rise and fall of EROI in oil and gas production in Canada
between the end of the second world war and the financial crisis. It
illustrates clear rise and fall in EROI over the time period. A similar study
for the US found that the EROI of US oil and gas production increased from
around 16:1 in 1920 to around 30:1 in 1970. Subsequently, however, the
EROI declined and in 2010 was estimated to be only 10:1. Most EROI studies
across multiple countries show declining EROI in the last two to three
decades. So the idea that the rise and fall in labour productivity growth has
something to do with the underlying physical resources is certainly not
fanciful.
25
On the other hand, Figure 6 doesn’t particularly support the idea that
secular stagnation is a demand-side phenomenon. Labour productivity can
decline in an economy in recession, because of labour hoarding – firms hang
on to people rather than letting them go, in expectation that things will get
better soon and in the hope of avoiding rehiring costs. For this reason,

labour productivity growth tends to fall naturally during a recession. But the
sustained decline in labour productivity growth witnessed during the last 5
decades suggests a much less cyclical trend, which can’t quite be explained
through labour hoarding.
Another possible candidate for the decline is the structure of both demand
and supply. Late modern economies are characterised by a shift from
primary and secondary manufacturing of material products towards the
provision of services. This shift occurs both in the supply structure of the
economy (for a variety of reasons) and the demand structure. On the supply
side, there is a tendency for advanced economies to export basic extraction
and processing activities to countries with lower labour costs and lower
environmental regulations.
On the demand side, it is possible that, once basic material needs are
satisfied, people turn more to service-based activities as the destination for
disposable income, rather than to even more material products. Service-
based activities are generally understood to be less amenable to growth in
labour productivity – partly because the core-value proposition in such
activities relates to the time spent by human beings in delivering the service.
In other words a mixture of demand side changes and the supply side
implications of those changes could be behind the decline witnessed in
Figure 6.
26
Finally, it is possible that the financial structure of the global economy plays
some role in the plight in which advanced economies in particular appear
now to find themselves. In support of growth, advanced economies in
particular have attempted to increase liquidity through a mixture of
financial innovation, low interest rates, and (more recently) direct monetary
financing (particularly of the financial sector itself). This has tended to
stimulate speculative investment at the expense of productive investment
in the real economy. Whether this has held back labour productivity growth
is not entirely clear. It has certainly made it more difficult to invest in the
transition to low-carbon and resource efficient technology which might
offset the environmental limits to growth. It has also had some profound
social and political implications, as we shall now see.

4 The Age of Inequality
In 2014, the French economist Thomas Piketty published his treatise on
Capitalism in the 21st Century. It was an immediate, if unlikely, best-seller: a
voluminous economic text book that had a global impact. Its fame rested
on two main features. The first was the spotlight that it shone on rising
inequality, particularly in the advanced economies. Specifically, Piketty and
his colleagues showed that the post-tax income of the richest percentiles of
the US population received a rising share of the national income over the
past half century. By 2015, the richest 10% of the population received almost
40% of the national income, higher than at any time since 1945. The post-
tax income share of the richest 1% had risen even faster than that of the top
10%, and by 2015 stood at over 15% of the national income, higher than at
any point since 1940 (Figure 8).
Figure 8: Post-tax income shares of top 10% and top 1% in the US: 1935-2015
Source: Author’s workings using data from Piketty et al 2017
The second striking feature of Piketty’s bestselling work was a particular
argument about the causes of rising inequality. Specifically, the French
economist argued that rising inequality was a direct and inevitable result of
the declining growth rate. There are various heuristic arguments to support
this view. Certainly, there’s an uncanny inverse resemblance between the
U-shaped curve shown in Figure 8 and the inverted U-shaped curves shown
in Figures 6 and 7. Could it be that rising economic growth, built on

increased labour productivity, is precisely what allowed society to reduce
inequality through the first half of the 20th Century?
This was precisely the idea behind what became known as ‘trickle-down’
theory: the hypothesis that economic growth is the best (and perhaps only)
way to bring poor people out of poverty and reduce the inequality that
divides society and undermines political solidarity. It was President
Kennedy who popularised the idea that a ‘rising tide lifts all boats’. Wealth
generation for the richest should flow back into society as the rich spend
their income on more and more goods and services. Setting aside for the
moment the environmental impacts of this increased throughput, the
process should at least allow for income growth amongst the very poorest,
who would find employment in the manufacturing sectors that provided for
this increasing expenditure. With labour productivity rising, production
costs would fall, allowing employers to compensate their employees with
ever higher wages. With more spending power in the economy generally,
even the poorest sectors of society would be encouraged to spend more into
the economy. And so the virtuous cycle would continue.

In fact, as Piketty and his colleagues have shown, in the immediate post-war
years, the benefits of growth did flow predominantly to the poorest in
society. Between 1946 and 1980, the lowest income percentiles in the US
received the highest income growth, while the highest income percentiles
received the lowest income growth. The average real growth in per capita
GDP during the period was around 2%. Average income growth in the lowest
percentile was three times this, at 6%, while income growth in the richest
percentile was little more than half the economy wide average (Figure 9 –
blue lines and markers). Not surprising then, that inequality was broadly
declining over that period.
In the period since 1980, the story has been a very different one. Average
income growth in the US was lower to start with, at only 1.4%, on average
between 1980 and 2014. But the striking part of the story was the reversal in
the fortunes of the poorest and richest as beneficiaries of that growth. The
incomes of the bottom 50% of the population grew at a meagre 0.6%, only
half the average rate of growth of the economy as a whole, while the incomes
of the richest 5% grew at 1.7% per annum, significantly above the average
income growth (Figure 9 – red lines and markers).
The story within the story is even more striking. Since 1980, it was
increasingly the super-rich who benefited from whatever growth the
economy could provide. The average growth rate of the top 0.001% of the
population was over 6%, allowing them to increase their post-tax earnings
by a factor of seven over the last three decades. The poorest 5% saw their
post-tax incomes fall in real terms over the same period.
Could declining labour productivity growth have had something to do with
this story? In theory, yes. Neoclassical economics assumes that wage
growth follows labour productivity growth. If each hour of work is 2% more
productive each year, then in theory, employers can afford to pay workers a
2% rise, without facing any additional costs. But when labour productivity
growth is falling or stagnant, wage growth is also sluggish, so that even
when GDP growth is buoyed up by fiscal or monetary policy, it tends to leave
workers on the whole less well off in the economy.
Figure 10 illustrates the relationship between labour’s share of income and
inequality in the US. It illustrates clearly the role that declining wage share
has had in rising inequality. Since the turn of the millennium in particular,
workers have seen less of the national income than the owners of capital.
Some of this decline could certainly be associated with the decline in labour
productivity.

When workers have more power than employees, for instance when the
employment rate is very high, then wage growth can exceed labour
productivity growth. Typically, this leads to higher costs for producers,
which must either be absorbed out of profits or else passed on to consumers,
leading to inflation, and potentially depressing the economy. On the other
hand, when employers have more power than workers, for instance when
unemployment is high and there is a surfeit of labour, they can depress wage
growth and reap the rewards of productivity growth as increased profits.
These dynamics appear to have favoured the bargaining power of capital
over the bargaining power of labour in recent years. Certainly, one of the
challenges of recent years is that, as productivity growth has slowed down,
the rate of labour compensation has been suppressed considerably below the
growth in labour productivity. Specifically, since the first oil crisis,
cumulative growth in the wage rate has fallen substantially below
cumulative growth in labour productivity (Figure 11).

Policy is critical in determining the effect of underlying economic factors on
social inequality. In the advanced economies over the last decades the
balancing act of fiscal and monetary policy has been to try and keep growth
going, while maintaining low levels of inflation. But a fall in the underlying
labour productivity growth has made this task increasingly difficult. We
have already seen how financial deregulation in pursuit of economic growth
was one of the factors leading to the financial crisis in 2008/9. Another of
the effects of this loose monetary policy was to exacerbate inequality.
There are several channels through which this acceleration of inequality
occurs. In the first place, cheap money leads to financial speculation. Those
with access to capital can achieve substantial capital gains as asset prices
rise. When wealth is already unequally distributed, this tendency leads
directly to higher income inequality. As income inequality increases, it leads
to excessive investment funds, because richer households tend to have a
high propensity to save than poorer ones. This excess of savings leads to
more speculation, pushing asset prices up again and accelerating inequality
further. But it also depresses growth, partly through the reduced spending
power of poorer households and partly through the crowding out of

investment in the real economy. Policy responses which attempt to
stimulate investment by reducing the interest rate, end up making money
cheaper and incentivising more speculation, fuelling a vicious cycle of rising
inequality.
27
The news is not all bad. Across countries, inequality has declined in recent
decades. The global Gini coefficient fell from almost 70 in 1988 to 62.5 in
2013, as the emerging and developing nations began to catch up with the
advanced economies.
28
Within these emerging and developing economies,
inequality has also declined – although Gini coefficients in such countries
tend still to be considerably higher than they are in advanced economies.
But across the advanced economies, inequality has increased and its
consequences are threatening to destabilise western democracy and
undermine political legitimacy.
29
All of this appears to support the hypothesis that rising inequality is an
inevitable result of a declining growth rate. Not only does a decline in labour
productivity leave wage earners less well off than the owners of capital, but
this trend appears to be exacerbated by factors which have depressed wage
growth in the advanced economies well below labour productivity growth,
leading to further inequality.
It is tempting at this point to accept Piketty’s case in its entirety:
“Capitalism in the 21st Century is faced with inevitable and rising inequality,
precisely because the growth rate is slowing down”. There are two core
strands to Piketty’s argument in defence of this claim. One of them concerns
the power that accrues increasingly to the owners of capital, once the
distribution of both capital and income becomes skewed. The power of
accumulated or inherited wealth to set the conditions for the rates of return
to capital and labour increasingly favours the owners of capital over wage-
earners and reinforces the advantages of the rich over the poor. This
certainly seems to be visible in the US data (Figure 11).
The other part of Piketty’s argument is a formal derivation which attempts
to relate the share of income flowing to the owners of capital as a function
of the growth rate. Specifically, Piketty shows that capital’s share of income
is directly proportional to the rate of return on capital multiplied by the
savings rate and inversely proportional to the growth rate. This inverse
proportionality on the growth rate means that, all things being equal, as the
27

growth rate falls, the share of income going to the owners of capital will rise.
Unless the distribution of capital is itself entirely equal (a situation which
clearly does not pertain at the moment) the relationship therefore presents
the spectre of an explosive rise in inequality as the growth rate declines to
zero.
30
Figure 12: Income inequality with an unequal distribution of capital assets
Source: Jackson and Victor 2017, Figure 5; solid lines indicate scenarios where the savings rate
remains unchanged over the course of the run; dashed lines indicate scenarios where the savings
rate falls to zero as the growth rate declines; the red lines indicate a high elasticity of substitution
between labour and capital (when it is easy to substitute capital for labour); green lines represent
low elasticity (where it is harder to substitute capital for labour); the blue lines represent the case
where the elasticity of substitution is 1.
31
In fact, it turns out (Figure 12) that the ceteris paribus clause is absolutely
vital. The behaviour of the share of income going to capital depends
crucially on what happens to the savings rate in the economy. It also
depends on what happens to the rate of return on capital, and this in its turn
depends on something called the elasticity of substitution between labour
and capital – broadly speaking the ease with which it’s possible for the
owners of capital to substitute capital for labour. If the savings rate remains

constant (as Piketty assumed) and it is relatively easy for the owners of
capital to protect their returns by substituting away from costly labour with
cheap capital, then it is indeed possible for income inequality to rise
explosively as growth rates decline.
However, there is absolutely no inevitability at all that a declining growth rate
leads to explosive (or even increasing) levels of inequality. If the savings rate
remains constant, but the elasticity of substitution between capital and
labour is low, a radically different future emerges, wage labour is protected,
the rate of return on capital falls as capitalists continue to try and save, but
income inequality declines significantly.
In reality, this latter scenario is not particularly likely to occur. It is more
likely that any decline in the rate of return on capital would lead to a
declining savings rate. When this happens, the economy is considerably less
sensitive to the substitutability between labour and capital. Rates of return
fall more or less slowly according to whether the elasticity of substitution is
(respectively) lower or higher, but in both cases remain comparable with
those achieved in a growing economy. Income inequality falls in both cases,
even before fiscal interventions. Not surprisingly, fiscal interventions are
considerably more effective in such an economy than in one with constant
savings and high elasticity of substitution.
The most worrying counter-example is the case where there is a continual
increase in the capital-to-output ratio and a high substitutability between
capital and labour. It is possible to envisage scenarios in which this occurs.
For instance, with increasing automation dominated by relatively few
companies with a high degree of monopoly power over labour, there are
clearly conditions under which income inequality increases significantly,
posing exactly the dangers that Piketty has highlighted.
On the other hand, it is possible to envisage circumstances in which there is
far less substitutability between labour and capital even under conditions of
rising capital to output ratio such as those that might prevail in the
transition to a low-carbon economy. This would of course involve protecting
the quality and intensity of people’s time in the workplace from substitution
by the owners of capital. But such a proposal is not a million miles from
suggestions that government should act as ‘employer of last resort’ in
stabilising an unstable economy.

In short, the idea that rising income inequality is an inevitable consequence
of falling growth rates is fundamentally wrong. On the contrary, an economy
with a declining growth rate might equally be headed towards lower income
inequality and greater stability of employment. The choice, it turns out, lies
in the underlying structure of economic relations and, in particular, in the
relations between labour (the workforce in paid employment in the economy)
and capital (the owners of productive and financial assets).
5 Confronting the Post-Growth Challenge
A decade after the onset of the financial crisis, governments around the
world are as wedded to the goal of economic growth as they have ever been.
The expectation is that a return to ‘normal’ levels of growth will not just
solve our economic woes, but is the only possible way to bring poor people
out of poverty.
In the name of growth, successive governments have justified austerity,
reduced their commitments to welfare spending, cut taxes for the richest
and withdrawn vital safety nets for the poorest in society. These regressive
policies are busy compounding the injustice of income inequality with
something even worse: inequalities in healthcare, in longevity, in basic
security, in human dignity. These new and deepening inequalities are
beginning to undermine the social fabric of society and threaten political
stability.
The same strategy is depleting finite resources and placing increased risks
on the environment. Declines in the quality of physical resources are already
evident and the dynamics of depletion place ever greater costs on society.
Authoritative estimates of the costs associated with unmitigated climate
change are salutary. Without investment in newer cleaner technologies,
these additional risks will also depress the potential for growth.
Behind these conditions lies a steady decline in the rate of growth of labour
productivity, stemming from roughly half a century ago (Figure 6). The
reasons for this decline are contested. Some point to a variety of secular
‘headwinds’ – such as rising debt overhang – which slow down demand, as
well as to basic technological factors that put the brake on supply. Others
have pointed to a diminution in demand in the advanced economies in
particular.

28 | CUSP WORKING PAPER No. 12
There remains a disturbing possibility that the huge productivity increases
that characterised the early and middle twentieth Century were a one-off,
something we can’t just repeat at will, despite the wonders of digital
technology. A fascinating – if worrying – contention is that the peak growth
rates of the 1960s were only possible at all on the back of a huge and deeply
destructive exploitation of dirty fossil fuels (Figure 7); something that can
be ill afforded – even if it were available – in the era of dangerous climate
change and declining resource quality. Low (and declining) rates of
economic growth may well be the ‘new normal’.
The critical question is how policy should respond to this not-so-new reality.
Over the last few decades, capitalism has had a very specific response. From
the early 1970s onwards, falling labour productivity growth has been
rewarded with even lower wage growth (Figure 11). Faced with diminishing
returns, producers and shareholders have systematically protected profit by
depressing the rewards to labour. Governments have encouraged this
process through loose monetary policy, poor regulatory oversight and fiscal
austerity. The outcome for many ordinary workers has been punitive. As
social conditions deteriorated, the threat to democratic stability has become
palpable.
The prevalent ‘rescue narrative’ relies on an assumption that productivity
growth will recover, primarily through new technological breakthroughs.
Candidate ‘saviours’ in these rescue narratives are various. For some,
innovation will arrive from investment in the same clean, low-carbon
technologies that are needed to tackle climate change and offset resource
depletion. For others, innovation will come from a new digital revolution:
increased automation, robotisation, artificial intelligence.
But the conditions for any of this enhanced investment remain uncertain at
best. Financial instability, debt overhang and rising inequality haunt the
financial ecosystem within which these new investment portfolios must
flourish. The dynamics of loose monetary policy continue to favour
speculation in financial assets rather than investment in the productive
capacity of the economy.
The low carbon investment scenario is particularly vulnerable to policy
uncertainty. Without clear regulatory guidance or a market price on carbon,
leveraging the trillions of dollars of investment needed to meet climate
change targets looks extremely challenging. Commitments to the Paris
Agreement have yet to be met with clear delivery plans.

29 | CUSP WORKING PAPER No. 12
The two investment strategies may also turn out to be in competition with
each other. While some believe that enhanced automation will reduce our
overall carbon footprint, the current evidence for this is at best partial and
mostly anecdotal. It is essentially a strategy that substitutes capital for
labour on a massive scale. Since capital assets require material inputs, the
likelihood is that it will have a higher resource footprint and higher carbon
emissions than a strategy that is more labour intensive.
The social consequences of increased automation might be even more
unpalatable than the environmental impacts. In particular, without quite
radical policy intervention, including a massive redistribution in the
ownership of capital assets, the enhanced automation scenario is likely to
lead to an unequal and increasingly polarised society. Of particular concern
is that these technologies are qualitatively different from those which
produced the massive rise in productivity growth up to the mid 1960s.
The technological revolution of the 19th and early 20th Century tended to
increase the potential for workers to improve their productivity of their
labour. This led to higher wages and greater spending power in the economy.
The expansion of consumer demand provided a further stimulus to growth
and productivity improvement. Putting technology in the hands of workers
created new jobs in the economy and allowed for a general improvement in
the quality of life of citizens.
There is a real danger that new digital and robot technologies will remove
the need for whole sections of the working population, leaving those who
don’t actually own the technologies without income and without bargaining
power. Meanwhile the owners of these technologies are likely to acquire
unprecedented market power, and the conditions for ordinary workers will
deteriorate even further. This is essentially the world described by the upper
line in Figure 12 above, in which it becomes easy to substitute capital for
labour, difficult to maintain demand and impossible to stop inequality rising
steeply.
33
Reaching beyond these potentially destructive conditions is not impossible.
There is an emerging interest in ideas around de-growth and in the
economics of a potential ‘post-growth’ society.
34
These approaches tend to
accept that beyond a certain point, and for a variety of reasons, economic
growth is neither desirable nor indeed feasible. Whether for secular reasons,
or from a decline in resource quality, or from the need to curtail damaging
33

environmental impact, proponents of these ideas attempt to envision the
social conditions (and economic implications) of a world in which, for the
advanced economies at least, it is necessary to do without growth.
Addressing inequality under such conditions is a particular concern.
Reaching one or other of the worlds described by the lower lines in Figure
12 requires us to confront certain fundamental aspects of capitalism. For
example, without a proactive distribution of resources, it is difficult to see
how the social devastation of a highly unequal society is to be avoided.
Without proactive labour and income policies, it is difficult to see how
incomes for ordinary people can be maintained, let alone improved. And
without state investment, it is difficult to see how basic services can be
maintained for the majority of the population.
A key issue for government, in conditions of declining growth, is the ability
to maintain the fiscal headroom within which to protect democratic
legitimacy. Electorates tend to punish administrations badly when social
investment falls. If declining growth is met with fiscal austerity it is likely to
lead to progressively worse social outcomes and increasing political fragility.
One way in which government may attempt to improve this situation is
through recovering political control over the creation and supply of money.
Some surprisingly conventional voices have called for an end to banks’
power to create debt-based money and the implementation of a so-called
‘sovereign money’ system.
A recent IMF working paper identifies several clear advantages to this,
better control of credit cycles, the potential to eliminate bank runs, and
dramatic reductions in both government and private debt. Under such a
system the state would no longer have to raise money for investment and
welfare on commercial bond markets. Instead they could spend directly into
the economy, as and when financing was needed, subject only to the caveat
that such spending was non-inflationary. Proposals for such systems are
currently under consideration in Iceland and in Switzerland.
35
Such ideas tend to be regarded at best as marginal distractions by
mainstream economists and at worst as obstacles to growth. Sectors which
make vital contributions to our quality of life, provide decent work, and
substantially reduce our material footprint are derided as ‘stagnant’ because
35

31 | CUSP WORKING PAPER No. 12
they have a lower potential for labour productivity growth. Social
investment is seen as irrelevant to the pursuit of profit.
In a growth-obsessed world it is easy to end up overlooking the parts of the
economy that matter most to human wellbeing. By understanding and
planning for the conditions of the ‘new normal’ associated with low growth
rates, it is possible to identify more clearly the features that define a
different kind of economy. A simple shift of focus opens out wide new
horizons of possibility.
Another such ‘backstop’ policy, which has received increasing attention
recently is the idea of a universal basic income. When the availablity of wage
labour declines and the downward pressure on wage growth increases, the
dynamics of inequality sharpen considerably. In the absence of policy
measures to combat these conditions, they are likely to lead to further
stagnation in demand and increasing political instability. The provision of a
universal basic income at a level sufficient to ensure basic minimum living
standards could do much to offset these destabilising influences.
36
Elaborating on these ideas is beyond the scope of this paper. Rather, my
principal aim has been to tease out the underlying dynamics of a global
economic and social system in crisis. In the process I have attempted to
illustrate more precisely how the strategy of chasing after growth in the face
of challenging fundamentals is leading to rising instability and the fractured
politics of a deeply unequal world.
But the suggestion that rising inequality is somehow an inevitable result of
a decline in the growth rate is fundamentally wrong. More correct would be
to argue that rising instability (both social and financial) is result of trying
to protect the growth rate in the face of an underlying decline in productivity,
by privileging the interests of the owners of capital over the interests of
those employed in wage labour in the economy. Reversing this trend by
raising the labour productivity growth rate through selective technologies is
a highly uncertain strategy that may exacerbate the environmental and
social problems of the 21st century.
In the light of that analysis, it is clearly pertinent to look beyond the
outcomes associated with the continued pursuit of the prevailing economic
paradigm. Elsewhere, I have argued that the task of elaborating a less

32 | CUSP WORKING PAPER No. 12
capitalistic, more resilient post-growth economy is precise, definable,
meaningful, and pragmatic.
37
Clearly, such ideas fly in the face of much conventional wisdom. They will
be most challenging of all for highly capitalistic societies. But the dangers
for capitalism are not confined to the challenge from emerging economies
for whom the transition may be easier. The dynamics of the existing growth-
based paradigm are driving environmental damage, exacerbating social
inequality and contributing to increased political instability. There has
never been a more urgent need to question the growth imperative. There has
never been a more opportune time to develop the design concepts for a
resilient post-growth society.
