Chapter 7 of ‘In
Open Seas’
In
the last 200 years, world per capita incomes (measured by market output) have
risen over ten times on average– more so in the most affluent countries. In the
previous 200 years they are thought to have risen about 10 percent. Can the
miracle growth of the last two centuries continue? Stein’s law says that ‘if
something cannot go on forever, it will stop’. But when? Perhaps ‘soon’, at
least for the affluent economies.
Secular
stagnation is the notion that affluent economies are moving into a low economic
growth stage for a long period, if not forever. (For economists, ‘secular’
means the ‘long term’, of indefinite duration.) Are we there yet?
There
are some economists who think that the world economy may already be in secular
stagnation and that GDP per capita will not grow much in the long term. Indeed,
secular stagnation has been a common concern of the profession; among the
greats who have pondered on it are Thomas Malthus, David Ricardo, Karl Marx,
John Maynard Keynes and Joseph Schumpeter. However, there is no consensus among
today’s economists that the rich economies face the prospect of long-term
stagnation compared to their experiences of the last two centuries. There is
even less consensus on why it may happen.
It
is generally accepted that international real (adjusted for inflation) interest
rates are low compared to the past and are likely to remain low for some time.
In principle, low interest rates ought to stimulate an investment boom, but
none is evident. That seems to suggest that in rich countries businesses do not
see growth opportunities.
Business
sees opportunities in poorer countries, although they may be hesitant to invest
there because of political instability. Many poorer economies are growing
faster than the rich ones. However, even the economic growth of the star
performer, China, is slowing down. Japan too, was once growing very quickly but
it slowed to the rich economies’ rate once it caught up. This suggests the
rapid growth occurred by Japan as a poor country adopting rich countries’
technologies. Once that had and Japan was using the top ones, its economy
slowed down to their rate.
Another
concern is that much of today’s growth is dependent upon ultimately
unsustainable financial behaviour. There is bound to be at least another major
financial crash sometime in most readers’ lifetimes and that will almost
certainly set back the international (or individual countries’) growth track.
Mechanisms
Ending Growth
Why
might growth rates in rich economies stagnate? Here are some possible
explanations. They are not exclusive.
First,
the shift from the non-market economy to the market economy – evident in
the rise of food preparation (and consumption) outside the home, that home
dressmaking is much less common and that more of childcare occurs outside the
family – may be near exhausted. New Zealand has already very high labour force
participation by women – among the highest in the world. Can we squeeze any
more blood out of the kitchen?
Second,
if economic growth has been as dependent on consuming natural resources, as
the previous chapter explored, then we may be reaching the point where such
exploitation is ending, especially if we stop using as sumps for polluting
waste air (greenhouse gases and smoke emissions), fresh (waste and runoff) and
sea water (including plastic bags) – the alternatives are more expensive
measured in GDP terms.
Third,
it is possible there is a slowdown of new growth-promoting technologies compared
to the last two centuries. As Chapter 4 discussed, economists think that a
major drive of economic growth has been technology rather than capital
accumulation. This may explain why poorer countries are still growing. They are
upgrading their technologies to rich-country levels. When they reach that
level, they will grow at the rich-country rates.
American
economist Robert Gordon, who has done more research in the area than anyone
else, argues that today’s innovations are not comparable to those of a century
ago – like electricity and the internal combustion engine. We may know whether
he is right in a hundred years, although there certainly seems to be an ongoing
multitude of new innovations if not as dramatic as the ones Gordon cites.
Why?
One possibility is that the technologies at the back of the warehouse (Chapter
4) are less exciting than the one’s near the front which have already been
discovered. I am not sure about that. One suggestion is that those at the back
are harder to get at, since the researcher has to work their way through all
the technologies at the front of the warehouse, so one needs to know a lot more
nowadays.
A
third possibility is that the new technologies do not give a commercial
return. For instance, the contribution to wellbeing of new pharmaceutical
drugs, costly to generate, may far outstrip their contribution to GDP. (Not
in Narrow Seas mentions the impact of efficient contraception which hardly
appears in GDP but made a dramatic impact to wellbeing.)
A
variation on the social valuable innovations which don’t give commercial
returns is infrastructure, which is often cited as generating a high return to
the economy. Generally the return does not go directly to the investor but is
spread widely, which is why private investors tend to be uninterested (unless
there is a public subsidy). While public-debt-constrained governments have
difficulties funding infrastructure without raising taxation, motorists sit
fuming in a traffic jam unwilling to pay the taxes to improve roads.
A
fifth possibility is there are increasingly severe difficulties measuring
conventional economic growth as we shift from the product economy to the
service economy.
A
sixth is that the degree of monopolisation seems to be increasing in key
sectors with the incumbents resisting new entrants. This may be because they
are often ‘common carriers’ (natural monopolies) with the technologies
favouring only one significant provider. (Examples are the immensely profitable
Facebook and Google whose revenue comes more from advertising than the services
they provide to users – similar to newspapers.) That may slow down economic
growth by stifling genuine innovation. (I certainly think that natural
monopolies should be regulated in the public good. If that generates economic
growth as well as improving wellbeing, so be it.)
A
seventh possibility is that secular stagnation is a rich-economy phenomenon
because the rich countries offshore production to poorer economies. I
wrote about this in my Globalisation and the Wealth of Nations.
Essentially, the ability of poor countries to produce many of the same products
using lower paid workers switches economic growth in their favour, whereas in
the past circumstances favoured the now-rich producers. Even so, there remain
opportunities for affluent countries to provide advanced precision products, as
Germany’s capital goods exports to China demonstrates.
The
world’s regional balance of economic activity is always changing, which must
imply some regions are in relative decline. Once Northern England was more
affluent that Southern England (which is why many New Zealander’s
nineteenth-century ancestors came from the south). Booming parts of the US are
now rust-belts. The South Island once had a larger population than the North
Island. Over the long run, there are changes in the relative rankings of
economies by per capita GDP. Observe that in Europe and the US economic
development moved from increasingly congested centres to the periphery (in
Europe from Britain to Finland and the Mediterranean; in the US from the
Northeast and Midwest to the South and Pacific West). Now, the same processes
move industry offshore, so when Japan reached rich country status some of its
industries moved on to South Korea, Taiwan and South East Asia.
The
underlying economic model suggests that the developing country shifts its
labour out of its low-productivity farm sector into a medium-productivity
manufacturing sector which exports to the rich. (The cognoscenti will recognise
here a ‘Lewis’ model of growth; West Indian Arthur Lewis was the first
non-European Nobel Laureate economist.)
A
final theory is that a lot of economic growth is a kind of Ponzi scheme,
especially that which depends upon the financial sector. It argues that
investors are benefiting today from trading worthless financial paper with
others who expect similar returns in the future. One day they will not be
delivered. Such arrangements may not be illegal, but they are painful when they
collapse. Much of the 2008 Global Financial Crisis can be explained this way.
(Economic growth depending on environmental depletion is also a kind of Ponzi
scheme.)
Secular
stagnation may have begun towards the end of the twentieth century – perhaps as
the result of a slowing down of the rate of technological innovation which
could be commercialised (although others of the explanations above may have
also contributed). The financial sector speculative boom in the first decade of
this century disguised the sluggishness. The GFC ended the boom.
A
Stagnant New Zealand?
The
full model of the offshore movement of manufacturing to poorer countries (the
seventh possibility) has an interesting prediction, especially for New Zealand.
These new manufacturing countries will suffer a food deficit because their
agricultural sectors will not be able to deliver all the food demanded by the
more-affluent city workers. The price of foodstuffs then rises relative to the
price of manufactures.
That
has been already happening over the last forty-odd years because of
industrialisation in East and South East Asia. The rising prices have been to
New Zealand’s benefit (because it gets paid more for the same production). In
contrast, the food terms of trade had been generally falling in the twentieth
century before the 1980s.
This
adds to the promise for the New Zealand economy. The foundation of New
Zealand’s prosperity has been its resource base – especially, land, sun and
water – which it has processed and exported. Is New Zealand running out of the
resources to fully reap the gains?
What
if Economic Growth is Dependent Upon Environmental Depletion?
To
return to the second possible explanation. Suppose past economic growth has
been partially dependent upon depleting the environment (as well as
innovation). There are two major ways the depletion happens.
One
is that there is a resource – such as coal – which gets mined out. This may be
thought of as converting a not-priced non-market resource into a priced market
one (relating to our first possible explanation of why we may be facing secular
stagnation).
A
variation on this is that a resource may be used as a sump – sewerage and
runoff into water, carbon dioxide into the air. The implication is that if we
had a wider measure of economic activity it would include a measure of
environmental depletion analogous to capital depreciation in GDP. Thus far it
has proved difficult to calculate in a convincing way. Moreover, it would make
little difference to current measures of material wellbeing (consumption).
Rather the wellbeing would stagnate and fall in the future – sounds like a
Ponzi scheme.
But
environmental depletion may impact on material wellbeing. Suppose it was
decided to remedy the sumps or even just to stop using them. That would divert
resources which could be used for increasing consumption. Some people would say
that would increase their psychic wellbeing. Fair enough. (Robert Fulghum’s All
I Really Need to Know I Learned in Kindergarten says ‘Put things back where
you found them; clean up your own mess’.) Whatever such actions would do for
psychic wellbeing, the material economic outcome would appear as secular
stagnation.
A
slightly different issue is that much of New Zealand’s capital investment has
been shoddy – leaky and earthquake prone buildings for example. Like remedying
of environmental depletion, remedying poorly built structures will involve
redirecting economic activity from adding to material consumption to
consolidating past gains.
The
Implications of Secular Stagnation
Predictions
are hard to make, particularly about the future. So we do not know whether
international secular stagnation is something to really worry about, or just
another passing fad. However, I should not be surprised if economic growth
among the rich countries is markedly lower in the future than it has been in
the past. The secular stagnation scenario sees a continuous slow down but we
should not rule out crashes followed by a very slow recovery as happened in
2008 and after.
The
clue for me is real interest rates. Those in the US, which set world rates,
dropped from 5% p.a. in the 1980s, to 2% p.a. in the 1990s, and to just 1% p.a.
in the 2000s. Since the Global Financial Crisis occurred, they have averaged a
negative 1% p.a (yup, nominal interest rates have been below the rate of
inflation). They may recover but that is not what the forward looking long-term
interest rate on US government bonds says. Low interest rates are indicative of
a lack of investment opportunities relative to available savings.
There
is a terrible inertia in human thinking when it is not chasing frivolous
fashion. There is real danger we will not adapt to the new circumstances which
may be, if there is secular stagnation or much slower growth, totally different
from the experiences (particularly in rich countries) over the last two
centuries.
Adding
to the inertia of thinking about economic growth is that the growth rate and
the profit rate are inextricably entwined. Low long-term growth means low
long-term profitability. In the short-term business can squeeze wages, shifting
the share of total income towards profits, but that cannot go on for ever.
There is a basic long-run mechanism that drives profit rates towards interest
rates plus a risk premium. That is why some of the great stagnationist thinkers
saw an end of capitalism. Thus far capitalism has survived despite such
predictions, because of its ability to morph into new forms, overcoming the
inertia, or perhaps because technological innovations has kept generating new
commercial investment opportunities – up to now.
Even
so, practical inertia will not prevent the public rhetoric pressing for growth
will remain prominent. It is largely unaffected by evidence and research, so
why should new circumstances and evidence change its approach?
The
Risks of Overestimating Interest Rates
The
danger is that we base our future on the past growth rate; if it is markedly
lower we will make poor decisions. Suppose real interest rates remain near zero
but individuals plan their retirement on their savings based on a real return
of 5 percent p.a. (low compared to the rate many investment advisers talk
about). They are going to have a low-income retirement relative to their
working-age income and their plans (their New Zealand Superannuation benefit is
not going to grow much either).
They
may convince themselves they can get a higher return by investing in high risk
schemes. But not everyone can get a higher-than-average return on their
investment. Ergo, some are going to get lower returns. In a low-growth,
low-return economy some of those involved in risky investment are going to lose
a lot of their savings. (Not you of course, someone else.) People who lose
their savings are usually incensed, forgetting that it was they who decided to
invest in high-risk schemes. That some schemes proved fraudulent or
near-fraudulent heightens the anger. But other investments fail through bad
luck or events outside the control of the investment manager, especially if
they were betting on higher growth rates than the actual outcome.
The
same trap applies to business. If their plans are based on expected growth and
there is long-term stagnation, the firms will over-commit themselves and fail.
That does not mean there are no business opportunities during secular
stagnation – picture theatres were built during the Great Depression – but
there are fewer.
Similarly
for government investment, except that failure results in higher taxes or
public debt. It is fashionable to argue the case for public infrastructure but
the underlying case is a cautious one. There is a need for catchup of a
backlog, and some new infrastructure may be vital to wellbeing – addressing the
three (fresh, waste and storm waters), for instance. But such investment gives
a financial return (in higher tax revenues to the government) only if there is
economic growth.
So,
any transition from the high material growth rates of the past two centuries to
lower (or zero) ones will not be easy. Possibility the usual economic rules of
the last eighty-odd years are going to be stood on their head posing quite a
challenge.
How
We Might Cope with Slow Economic Growth in the Future?
Thinking
about the economic future one cannot avoid making some assessment of the likely
course of material economic growth. If it is going to be slower than rich
countries have been used to – there may even be secular stagnation. How are we
to cope?
Chapter
2 argued we should shift the economic focus from material economic growth to
wellbeing. But that does not mean that all the traditional concerns have become
obsolete.
People
still need jobs as a part of their involvement in their community and sense of
worth. Thus avoiding stressful unemployment (which includes
underemployment) and promoting quality job creation should be an important
public policy priority.
Inequality
is dealt with in a later chapter. There will be significant gains in aggregate
wellbeing by lifting the relative incomes of those at the bottom.
Economic growth which fails to change the relativities is of little relevance.
Diversity
should be celebrated, with tolerance and respect. No group is privileged, but
attention should be paid to the smaller ones. I have spent my entire life as a
minority of one – so have you, if you have an independent sense of your
self-worth. There is a current fashion to promote a society based on love. That
seems to me to be a bit excessive in the case of some people, but we should be
kind to them.
At
our level of affluence, material consumption is not as important as the quality
of life. That gives great significance to health care in all its
dimensions. That care needs resources (as well as kindness). But we need to
break away from assessments like ‘adopting my policies is worth so many
billions of dollars’ which plays into the hands of those overemphasising GDP.
The
same approach should be applied to safety – both personal and physical.
It is not an area I know a lot about, although the law and order brigade seems
to know even less.
Opportunity,
or as Amartya Sen describes it, achieving capabilities is a key element
of the good society and of individual wellbeing. A crucial element of that
capability for each of us is creativity and achievement. There are so many
social impediments to many New Zealanders being able to achieve what they are
capable of. That is discussed in future chapters including the way education
system has been captured by commercial considerations aimed at lifting GDP. The
result is that people’s access to developing their capabilities has been
limited. It is a repeat of an earlier theme. Prioritising material output in an
affluent society damages wellbeing.
Finally
in the list is sustainability. Earlier generations bequeathed to my
generation opportunity and wellbeing. We owe the same to later generations.
Observe
that the above list of objectives applies whether the affluent society is in a
growth boom or in secular stagnation.
The
list does not rule out the market economy, nor the need for a high-level – but
sustainable – material output. But we should not confuse any analysis of growth
with wellbeing; as the Maslow hierarchy makes clear, we should not be obsessed
with GDP in the way that neoliberal policies have been.
Nor
does the analysis reject an honourable role for business. It contributes to
wellbeing in a number of ways. This is its purpose, not the pursuit of material
output, as sadly Rogernomics thought. Business needs to be humble about what it
can do, as we all need to be.
