Herman Daly: Towards A Steady-State Economy
It is doubtful we can adequately inform energy policy without addressing the linkages between equity, the environment, finance, and our end goals. I post this on theoildrum not only because Herman is one of my tribal elders but because his eloquence, courage and foresight on these issues have historically been, and continue to be, ahead of the curve. During his resignation speech from the World Bank, Herman recommended the Bank take "a few antacids and laxatives to cure the combination of managerial flatulence and organizational constipation giving rise to such a high-pressure internal environment." To improve interactions with the external world he prescribed "new eyeglasses and a hearing aid."
Nearly 15 years later, here is Professor Daly's current synopsis of the state of economics and his prescriptions for change.

A Steady-State Economy(Editors note: underlined words are in original; bold, italicized, hyperlinks and images added)
A failed growth economy and a steady-state economy are not the same
thing; they are the very different alternatives we face.
The Earth as a whole is approximately a steady state. Neither the
surface nor the mass of the earth is growing or shrinking; the inflow of
radiant energy to the Earth is equal to the outflow; and material imports
from space are roughly equal to exports (both negligible). None of this
means that the earth is static—a great deal of qualitative change can
happen inside a steady state, and certainly has happened on Earth. The
most important change in recent times has been the enormous growth of
one subsystem of the Earth, namely the economy, relative to the total
system, the ecosphere. This huge shift from an “empty” to a “full” world
is truly “something new under the sun” as historian J. R. McNeil calls it in
his book of that title. The closer the economy approaches the scale of the
whole Earth the more it will have to conform to the physical behavior
mode of the Earth. That behavior mode is a steady state—a system that
permits qualitative development but not aggregate quantitative growth.
Growth is more of the same stuff; development is the same amount of
better stuff (or at least different stuff). The remaining natural world no
longer is able to provide the sources and sinks for the metabolic
throughput necessary to sustain the existing oversized economy—much
less a growing one.
Economists have focused too much on the economy’s
circulatory system and have neglected to study its digestive tract.
Throughput growth means pushing more of the same food through an
ever larger digestive tract; development means eating better food and
digesting it more thoroughly. Clearly the economy must conform to the
rules of a steady state—seek qualitative development, but stop
aggregate quantitative growth. GDP increase conflates these two very
We have lived for 200 years in a growth economy. That makes it
hard to imagine what a steady-state economy (SSE) would be like, even
though for most of our history mankind has lived in an economy in which
annual growth was negligible. Some think a SSE would mean freezing in
the dark under communist tyranny. Some say that huge improvements in
technology (energy efficiency, recycling) are so easy that it will make the
adjustment both profitable and fun.
Regardless of whether it will be hard or easy we have to attempt a
SSE because we cannot continue growing, and in fact so-called
“economic” growth already has become uneconomic. The growth
economy is failing. In other words, the quantitative expansion of the
economic subsystem increases environmental and social costs faster than
production benefits, making us poorer not richer, at least in high consumption
countries. Given the laws of diminishing marginal utility and
increasing marginal costs this should not have been unexpected. And
even new technology sometimes makes it worse. For example, tetraethyl
lead provided the benefit of reducing engine knock, but at the cost
spreading a toxic heavy metal into the biosphere; chlorofluorocarbons
gave us the benefit of a nontoxic propellant and refrigerant, but at the
cost of creating a hole in the ozone layer and a resulting increase in
ultraviolet radiation. It is hard to know for sure that growth now increases
costs faster than benefits since we do not bother to separate costs from
benefits in our national accounts. Instead we lump them together as
“activity” in the calculation of GDP.
Ecological economists have offered empirical evidence that growth
is already uneconomic in high consumption countries (see ISEW, GPI,
Ecological Footprint, Happy Planet Index). Since neoclassical economists
are unable to demonstrate that growth, either in throughput or GDP, is
currently making us better off rather than worse off, it is blind arrogance
on their part to continue preaching aggregate growth as the solution to
our problems. Yes, most of our problems (poverty, unemployment,
environmental degradation) would be easier to solve if we were richer--
that is not the issue. The issue is: Does growth in GDP any longer really
make us richer? Or is it now making us poorer?
The classical steady state takes the biophysical dimensions—
population and capital stock (all durable producer and consumer goods)—
as given and adapts technology and tastes to these objective conditions.
The neoclassical “steady state” (proportional growth of capital stock and
population) takes tastes and technology as given and adapts by growth in
biophysical dimensions, since it considers wants as unlimited, and
technology as powerful enough to make the world effectively infinite. At a
more profound level the classical view is that man is a creature who must
ultimately adapt to the limits (finitude, entropy, ecological
interdependence) of the Creation of which he is a part. The neoclassical
view is that man, the creator, will surpass all limits and remake Creation to
suit his subjective individualistic preferences, which are considered the
root of all value. In the end economics is religion.
Accepting the necessity of a SSE, along with John Stuart Mill and
the other classical economists, let us imagine what it might look like. First
a caution—a steady-state economy is not a failed growth economy. An
airplane is designed for forward motion. If it tries to hover it crashes. It is
not fruitful to conceive of a helicopter as an airplane that fails to move
forward. It is a different thing designed to hover. Likewise a SSE is not
designed to grow.
Following Mill we might define a SSE as an economy with constant
population and constant stock of capital, maintained by a low rate of
throughput that is within the regenerative and assimilative capacities of
the ecosystem. This means low birth equal to low death rates, and low
production equal to low depreciation rates. Low throughput means high
life expectancy for people and high durability for goods. Alternatively, and
more operationally, we might define the SSE in terms of a constant flow
of throughput at a sustainable (low) level, with population and capital
stock free to adjust to whatever size can be maintained by the constant
throughput that begins with depletion of low-entropy resources and ends
with pollution by high-entropy wastes.
How could we limit throughput, and thus indirectly limit stocks of
capital and people in a SSE? Since depletion is spatially more
concentrated than pollution the main controls should be at the depletion
or input end. Raising resource prices at the depletion end will indirectly
limit pollution, and force greater efficiency at all upstream stages of
production. A cap-auction-trade system for depletion of basic resources,
especially fossil fuels, could accomplish a lot, as could ecological tax
reform, about which more later.
If we must stop aggregate growth because it is uneconomic, then
how do we deal with poverty in the SSE? The simple answer is by
redistribution—by limits to the range of permissible inequality, by a
minimum income and a maximum income. What is the proper range of
inequality—one that rewards real differences and contributions rather
than just multiplying privilege? Plato thought it was a factor of four.
Universities, civil services and the military seem to manage with a factor
of ten to twenty. In the US corporate sector it is over 500. As a first step
could we not try to lower the overall range to a factor of, say, one
hundred? Remember, we are no longer trying to provide massive
incentives to stimulate (uneconomic) growth! Also, since we are not
trying to stimulate aggregate growth, we no longer need to spend billions
on advertising. Instead of treating advertising as a tax-deductible cost of
production we should tax it heavily as a public nuisance. If economists
really believe that the consumer is sovereign then she should be obeyed
rather than manipulated, cajoled, badgered, and lied to.
Free trade would not be feasible for a SSE, since its producers
would necessarily count many costs to the environment and the future
that foreign firms located in growth economies are allowed to ignore. The
foreign firms would win in competition, not because they were more
efficient, but simply because they did not pay the cost of sustainability.
Regulated international trade under rules that compensated for these
differences (compensating tariffs) could exist, as could “free trade”
among nations that were equally committed to sustainability in their
domestic cost accounting. One might expect the IMF, the World Bank, and
the WTO to be working toward such regulations. Instead they vigorously
push both free trade and free capital mobility (i.e., deregulation of
international commerce). Protecting an efficient national policy of cost
internalization is very different from protecting an inefficient firm.
The case for guaranteed mutual benefit in international trade, and
hence the reason for leaving it “free”, is based on Ricardo’s comparative
advantage argument. A country is supposed to produce the goods that it
can produce more cheaply relative to other goods, than is the case in
other countries. By specializing according to their comparative advantage
both trading partners gain, regardless of absolute costs (one country
could produce all goods more cheaply, but it would still benefit by
specializing in what it produced relatively more cheaply and trading for
other goods). This is logical, but like all logical arguments comparative
advantage is based on premises. The key premise is that while capital
(and other factors) moves freely between industries within a nation, it
does not move between nations. If capital could move abroad it would
have no reason to be content with a mere comparative advantage at
home, but would seek absolute advantage—the absolutely lowest cost of
production anywhere in the world. Why not? With free trade the product
could be sold anywhere in the world, including the nation the capital just
left. While there are certainly global gains from trade under absolute
advantage there is no guarantee of mutual benefit. Some countries could
The IMF-WB-WTO ( Washington Consensus) contradict themselves in service to the interests
of transnational corporations. International capital mobility, coupled with
free trade, allows corporations to escape from national regulation in the
public interest, playing one nation off against another. Since there is no
global government they are in effect uncontrolled. The nearest thing we
have to a global government (IMF-WB-WTO) has shown no interest in
regulating transnational capital for the common good. Their goal is to help
these corporations grow, because growth is presumed good for all—end
of story. If the IMF wanted to limit international capital mobility to keep
the world safe for comparative advantage, there are several things they
could do. They could promote minimum residence times for foreign
investment to limit capital flight and speculation, and they could propose
a small tax on all foreign exchange transactions (Tobin tax). Most of all
they could revive Keynes’ proposal for an international multilateral
clearing union that would directly penalize persistent imbalances in
current account (both deficit and surplus), and thereby indirectly promote
balance in the compensating capital account, reducing international
One problem for the SSE already raised by the demographic
transition to a non growing population is that it necessarily results in an
increase in the average age of the population—more retirees relative to
workers. Adjustment requires either higher taxes, older retirement age, or
reduced retirement pensions. The system is hardly in “crisis”, but these
adjustments are surely needed to achieve sustainability. For many
countries net immigration has become a larger source of population
growth than natural increase. Immigration may temporarily ease the age
structure problem, but the steady-state population requires that births
plus in-migrants equal deaths plus out-migrants. It is hard to say which is
more politically incorrect, birth limits or immigration limits? Many prefer
denial of arithmetic to facing either one.
The SSE will also require a “demographic transition” in populations
of products towards longer-lived, more durable goods, maintained by
lower rates of throughput. A population of 1000 cars that last 10 years
requires new production of 100 cars per year. If more durable cars are
made to last 20 years then we need new production of only 50 cars per
year. To see the latter as in improvement requires a change in perspective
from emphasizing production as benefit to emphasizing production as a
cost of maintenance. Consider that if we can maintain 1000 cars and the
transportation services thereof by replacing only 50 cars per year rather
than 100 we are surely better off—the same capital stock yielding the
same service with half the throughput. Yet the idea that production is a
maintenance cost to be minimized is strange to most economists. Shifting
taxes from value added to throughput would promote this minimizing
effort. One adaptation in this direction is the service contract that leases
the service of equipment (ranging from carpets to copying machines),
which the lessor/owner maintains, reclaims, and recycles at the end of its
Although the main thrust of reforms for the SSE is to bring newly
scarce and truly rival natural capital and services under the market
discipline, we should not overlook the opposite problem, namely, freeing
truly non rival goods from their artificial enclosure by the market. There
are some goods that are by nature non-rival, and should be freed from
illegitimate enclosure by the price system. I refer especially to knowledge.
Knowledge, unlike throughput, is not divided in the sharing, but multiplied.
Once knowledge exists, the opportunity cost of sharing it is zero and its
allocative price should be zero. International development aid should more
and more take the form of freely and actively shared knowledge, along
with small grants, and less and less the form of large interest-bearing
loans. Sharing knowledge costs little, does not create unrepayable debts,
and it increases the productivity of the truly rival and scarce factors of
production. Existing knowledge is the most important input to the
production of new knowledge, and keeping it artificially scarce and
expensive is perverse. Patent monopolies (aka “intellectual property
rights”) should be given for fewer “inventions”, and for fewer years.
What would happen to the interest rate in a SSE? Would it not fall
to zero without growth? Not likely, because capital would still be scarce,
there would still be a positive time preference, and the value of total
production may still increase without growth in physical throughput—as a
result of qualitative development. Investment in qualitative improvement
may yield a value increase out of which interest could be paid. However,
the productivity of capital would surely be less without throughput
growth, so one would expect low interest rates in a SSE, though not a
Would it be possible to have qualitative improvement (e.g.
increasing efficiency) forever, resulting in GDP growth forever? GDP would
become ever less material-intensive. Environmentalists would be happy
because throughput is not growing; economists would be happy because
GDP is growing. I think this should be pushed as far as it will go, but how
far is that likely to be? Consider that sectors of the economy generally
thought to be more qualitative, such as information technology, turn out
on closer inspection to have a substantial physical base, including a
number of toxic metals.
Also, if expansion is to be mainly for the sake of the poor it must
be comprised of goods the poor need—clothing, shelter, and food on the
plate, not ten thousand recipes on the Internet. In addition, as a larger
proportion of GDP becomes less material-intensive, the terms of trade
between more and less material-intensive goods will move against the less
material-intensive, limiting incentive to produce them. Even providers of
information services spend most of their income on cars, houses, and
trips, rather than the immaterial product of other symbol manipulators.
Can a SSE maintain full employment? A tough question, but in
fairness one must also ask if full employment is achievable in a growth
economy driven by free trade, off-shoring practices, easy immigration of
cheap labor, and widespread automation? In a SSE maintenance and repair
become more important. Being more labor intensive than new production
and relatively protected from off-shoring, these services may provide
more employment. Yet a more radical rethinking of how people earn
income may be required. If automation and off-shoring of jobs increase
profits but not wages, then the principle of distributing income through
jobs becomes less tenable. A practical solution (in addition to slowing
automation and off-shoring) may be to have wider participation in the
ownership of businesses, so that individuals earn income through their
share of the business instead of through fulltime employment. Also the
gains from technical progress should be taken in the form of more leisure
rather than more production—a long expected but under-realized
What sort of tax system would best fit a SSE? Ecological tax
reform, already mentioned, suggests shifting the tax base away from
value added (income earned by labor and capital), and on to “that to
which value is added”, namely the throughput flow, preferably at the
depletion end (at the mine-mouth or well-head, the point of “severance”
from the ground). Many states have severance taxes. Taxing the origin
and narrowest point in the throughput flow induces more efficient
resource use in production as well as consumption, and facilitates
monitoring and collection. Taxing what we want less of (depletion and
pollution), and ceasing to tax what we want more of (income, value
added) would seem reasonable—as the bumper sticker puts it, “tax bads,
not goods”. The shift could be revenue neutral and gradual. Begin for
example by forgoing $x revenue from the worst income tax we have.
Simultaneously collect $x from the best resource severance tax we could
devise. Next period get rid of the second worst income tax, and
substitute the second best resource tax, etc. Such a policy would raise
resource prices and induce efficiency in resource use. The regressivity of
such a consumption tax could be offset by spending the proceeds
progressively, by the limited range of inequality already mentioned, and
by the fact that the mafia and other former income tax cheaters would
have to pay it. Cap-auction–trade systems will also increase government
revenue, and auction revenue can be distributed progressively.
Could a SSE support the enormous superstructure of finance built
around future growth expectations? Probably not, since interest rates and
growth rates would be low. Investment would be mainly for replacement
and qualitative improvement. There would likely be a healthy shrinkage of
the enormous pyramid of debt that is precariously balanced atop the real
economy, threatening to crash. Additionally the SSE could benefit from a
move away from our fractional reserve banking system toward 100%
One hundred percent reserves would put our money supply back
under the control of the government rather than the private banking
sector. Money would be a true public utility, rather than the by-product of
commercial lending and borrowing in pursuit of growth. Under the existing
fractional reserve system the money supply expands during a boom, and
contracts during a slump, reinforcing the cyclical tendency of the
economy. The profit (seigniorage) from creating (at negligible cost) and
being the first to spend new money and receive its full exchange value,
would accrue to the public rather than the private sector. The reserve
requirement, something the Central Bank manipulates anyway, could be
raised from current very low levels gradually to 100%. Commercial banks
would make their income by financial intermediation (lending savers’
money for them) as well as by service charges on checking accounts,
rather than by lending at interest money they create out of nothing.
Lending only money that has actually been saved by someone
reestablishes the classical balance between abstinence and investment.
This extra discipline in lending and borrowing likely would prevent such
debacles as the current “sub-prime mortgage” crisis. 100% reserves
would both stabilize the economy and slow down the Ponzi-like credit
A SSE should not have a system of national income accounts, GDP,
in which nothing is ever subtracted. Ideally we should have two accounts,
one that measures the benefits of physical growth in scale, and one that
measures the costs of that growth. Our policy should be to stop growing
where marginal costs equal marginal benefits. Or if we want to maintain
the single national income concept we should adopt Nobel laureate
economist J. R. Hicks’ concept of income, namely, the maximum amount
that a community can consume in a year, and still be able to produce and
consume the same amount next year. In other words, income is the
maximum that can be consumed while keeping productive capacity
(capital) intact. Any consumption of capital, manmade or natural, must be
subtracted in the calculation of income. Also we must stop the
asymmetry of adding to GDP the production of anti-bads without first
having subtracted the generation of the bads that made the anti-bads
necessary. Note that Hicks’ conception of income is sustainable by
definition. National accounts in a sustainable economy should try to
approximate Hicksian income and abandon GDP. Correcting GDP to
measure income is less ambitious than converting it into a measure of
welfare, discussed earlier.
The logic of the SSE is reinforced by the recent finding of
economists and psychologists that the correlation between absolute
income and happiness extends only up to some threshold of “sufficiency,”
and beyond that point only relative income influences self-evaluated
happiness. This result seems to hold both for cross-section data
(comparing rich to poor countries at a given date), and for time series
(comparing a single country before and after significant growth in
income). Growth cannot increase everyone’s relative income. The welfare
gain of people whose relative income increases as a result of further
growth would be offset by the loss of others whose relative income falls.
And if everyone’s income increases proportionally, no one’s relative
income would rise and no one would feel happier. Growth becomes like an
arms race in which the two sides cancel each other’s gains. A happy
corollary is that for societies that have reached sufficiency, moving to a
SSE may cost little in terms of forgone happiness. The “political
impossibility” of a SSE may be less than it previously appeared.
Nevertheless it is one thing to imagine the possibility of a SSE, but
something else to chart a transition thereto from a failed growth
economy. Can one transform an airplane into a helicopter without first
landing, or perhaps crashing? In order even to take such a task seriously
one has to realize that the growth economy is heading for a big crash.
Whether the measures suggested above are sufficient to convert the
growth airplane to a steady-state helicopter is hard to say, but I do think
they are probably necessary, and at a minimum would be useful guides for
reconstruction after the crash. They also may prove capable of being
applied gradually in mid air. For example, a cap-auction-trade system
could begin with a generous cap followed by a gradual pre-announced
schedule of tightening. The limits to income inequality could begin far
apart, and be gradually tightened. Ecological tax reform could substitute
at first only the worst value added taxes by the best throughput taxes, as
mentioned earlier. Compensatory tariffs to protect national costinternalization
policies could be imposed and raised gradually. Reserve
requirements for banks could be raised gradually to one hundred percent.
Patent monopolies could be gradually reduced and knowledge gradually
restored to its proper status as a non rival good. Downsizing of the IMFWB-
WTO from a servant of global integration in the interests of
transnational capitalist growth to something closer to Keynes’ nationbased
multilateral clearing union for international payments—this would
be more difficult to do gradually. But nations may begin individually to
withdraw from these institutions as it becomes more evident that they
have abandoned the federated internationalist nature of their Bretton
Woods Charter in favor of an economically integrated globalist vision of
capital-dominated growth, and are as yet incapable of conceiving the
possibility, much less recognizing the reality, of uneconomic growth.
While these transitional policies will appear radical to many, it is worth remembering that, in addition to being amenable to gradual application, they are based on the conservative institutions of private property and decentralized market allocation. They simply recognize that private property loses its legitimacy if too unequally distributed, and that markets lose their legitimacy if prices do not tell the whole truth about costs. In addition, the macro-economy becomes an absurdity if its scale is structurally required to grow beyond the biophysical limits of the Earth. And well before that radical physical limit we are encountering the conservative economic limit in which extra costs of growth become greater than the extra benefits.
Ten Point Policy Summary1. Cap-auction-trade systems for basic resources. Cap limits to biophysical scale according to source or sink constraint, whichever is more stringent. Auction captures scarcity rents for equitable redistribution. Trade allows efficient allocation to highest uses.
2. Ecological tax reform—shift tax base from value added (labor and capital) and on to “that to which value is added”, namely the entropic throughput of resources extracted from nature (depletion), through the economy, and back to nature (pollution). Internalizes external costs as well as raises revenue more equitably. Prices the scarce but previously unpriced contribution of nature.
3. Limit the range of inequality in income distribution—a minimum income and a maximum income. Without aggregate growth poverty reduction requires redistribution. Complete equality is unfair; unlimited inequality is unfair. Seek fair limits to inequality.
4. Free up the length of the working day, week, and year—allow greater option for leisure or personal work. Full-time external employment for all is hard to provide without growth.
5. Re-regulate international commerce—move away from free trade, free capital mobility and globalization, adopt compensating tariffs to protect efficient national policies of cost internalization from standards-lowering competition from other countries.
6. Downgrade the IMF-WB-WTO to something like Keynes’ plan for a multilateral payments clearing union, charging penalty rates on surplus as well as deficit balances—seek balance on current account, avoid large capital transfers and foreign debts.
7. Move to 100% reserve requirements instead of fractional reserve banking. Put control of money supply and seigniorage in hands of the government rather than private banks.
8. Enclose the remaining commons of rival natural capital in public trusts, and price it, while freeing from private enclosure and prices the non rival commonwealth of knowledge and information. Stop treating the scarce as if it were non scarce, and the non scarce as if it were scarce.
9. Stabilize population. Work toward a balance in which births plus immigrants equals deaths plus out-migrants.
10. Reform national accounts—separate GDP into a cost account and a benefits account. Compare them at the margin, stop growing when marginal costs equal marginal benefits. Never add the two accounts.
