Time to Stop Worshipping Economic Growth

By Brent Blackwelder

Brent Blackwelder

There are physical limits to growth on a finite planet. In 1972, the Club of Rome issued their groundbreaking report—Limits to Growth (twelve million copies in thirty-seven languages). The authors predicted that by about 2030, our planet would feel a serious squeeze on natural resources, and they were right on target.

In 2009, the Stockholm Resilience Center introduced the concept of planetary boundaries to help the public envision the nature of the challenges posed by limits to growth and physical/biological boundaries. They defined nine boundaries critical to human existence that, if crossed, could generate abrupt or irreversible environmental changes.

The global economy must be viewed from a macro-perspective to realize that infringement of the planetary boundaries puts many life support ecosystems in jeopardy. Without functional ecosystems, the very survival of life forms, as well as human institutions, is put in doubt, including any economy. There is no economy on a dead planet!

These boundaries apply to the economy because the economy is a wholly-owned subsidiary of the ecosystems that make life on earth possible. (Some understanding of ecology should be a prerequisite for an advanced degree in economics!) Scientists are concerned that we have already overstepped the boundaries on biogeochemical flows (nitrogen) and biosphere integrity (genetic biodiversity).

Today’s global economy and the various regional and national economies regularly neglect planetary boundaries. Crossing a boundary is tantamount to crashing through a guardrail and plunging over a cliff. The blind encouragement of economic growth that does not respect these boundaries is setting up human civilizations for collapse. Two of the most harmful types of growth are ruthless and futureless.

Ruthless growth benefits a few at the top but does nothing for the middle class. One of the reasons that Bernie Sanders’ presidential campaign has attracted larger and larger audiences is that he says the most crucial issue facing the United States is the gross discrepancy between the middle class and the billionaire class.

Futureless growth destroys resources, such as water, forests, fisheries, and farmland that will be needed by our children and grandchildren, and by wildlife. Futureless growth directly conflicts with common family values. We tell our children to save for the future rather than squander their money. We don’t tell them to outspend their peers. We don’t tell them to judge the quality of their lives based on material possessions and quarterly financial reports.

To remain within the nine planetary boundaries, nations must shed the fetish of economic growth and transition to a true-cost, steady state economy. Some of the critical transition steps include:

  1. Replacing the GDP as a measure of well-being (lots of work has been done on coming up with an index of sustainable productivity).
  2. Getting the Securities and Exchange Commission (SEC) to require corporations to disclose their pollution externalities (the SEC is not hopeless, as can be seen by its recent decision to require CEOs to publish their salaries along with those of the average workers at their companies).
  3. Going to a four-day work week to secure fuller employment (this has happened in some European countries; Canadian economist Peter Victor has papers on why this is a crucial transition step).
  4. Dematerializing the economy (i.e., so that it’s cheaper to repair an appliance than it is to buy a new one).
  5. Identifying the areas in which the economy should grow—and those where it should shrink or degrow (i.e., the usage of fossil fuels must shrink sharply, and in so doing, roof-top solar will grow to become a much larger part of the global economy).
  6. Identifying the most heinous types of economic growth (ruthless and futureless) and showing how their costs exceed their benefits.
  7. Stabilizing population to keep humanity from further transgression of the nine boundaries.

There are about seven billion people on earth today, and forecasts indicate there will be nine billion by 2050. Already, almost one billion malnourished people are feeling the squeeze, as they painfully bear testimony to the truth of what Malthus predicted two centuries ago. Key first steps to stabilizing population in a progressive way are:

  1. Empowerment of women.
  2. Requiring all foreign assistance to be designed so that women will be better off as a result.
  3. Making contraceptives widely available.

Our global economy is treating the planet as if it were a business in a liquidation sale. Even environmental organizations—devoted to environmental protection— have been slow to acknowledge the major causes of environmental degradation, such as perverse economic incentives encouraging raw resource extraction and non-renewable energy use. We need environmental leaders to speak out for a new, just, and true-cost economy; and to challenge the mindless embracing of economic growth—even ruthless and futureless growth. Environmental leaders should be driving the push toward refocusing economic thinking on the changes that we will have to make if we are going to move to a healthier economy that exists within the nine planetary boundaries. Only if humanity stays within these nine boundaries can it continue to develop and thrive for generations to come.



Appropriate Scarcity

By Robert A. Herendeen

  … appealing to people to restrain themselves [by] self-enforced abstinence alone is a waste of time. By and large, we consume as much as our incomes allow…. changes… cannot take place without constraints that apply to everyone rather than everyone else. Manmade global warming cannot be restrained unless we persuade the government to force us to change the way we live.

—George Monbiot, Heat (2006/2009)

The results indicate that the likelihood of paying a positive amount for supporting renewable energy is higher under a mandatory scheme compared to a voluntary payment option in the UK.

—Elcin Akcura, “Mandatory vs. voluntary payment for green electricity,” Ecological Economics (2015)


herendeen.3I believe Monbiot says it true. And Akcura (who knew?) provides research-based confirmation.

I envision fulfilling, challenging, joyful lives within environmental constraints, but I can’t imagine that happening without societal signals to reinforce consistent behavior. If level of consumption is a problem, then scarcity is a necessary part of the solution. In the least disruptive and potentially fairest sense, this means using prices to determine demand. To cut to the conclusion: my favorite example is a carbon tax.

Monbiot’s statement is frightening, Draconian, and an apparent non-starter politically… almost. But the consequence of denying it leads to several futile proposals and viewpoints which permeate the literature, both scholarly and public. They are futile because they do not produce results that are big enough and fast enough to beat back anthropogenic climate change. Hearing them repeatedly frustrates me. These are:

1. We citizens are being sold the idea that economic growth (especially GDP) is good by government bureaucracies that need it to stay alive, and by corporations that want it because they are greedy (e.g., “the 1%”).

2. We are personally acquisitive because of intensive advertising. Otherwise, we would readily embrace “enough is plenty.”

3. A steady state economy will only be achieved when a new human consciousness emerges. That is not exactly imminent, but it’s in sight.

4. Peer pressure will solve the classic (game theoretic?) problems of free riders, defection, and over-riding competitive ambition in general.

The human beings that I observe, work and live with, and love, largely don’t fit these principles. This includes me. We need help. So, about these points:

1. Most of us don’t know or care what GDP is. However, we do have explicit or implicit desires for material/experiential growth at the personal or familial level. Such as: a larger house, a vacation cottage, a new car, a foreign eco-tour, increased travel to visit the grandkids, a secure college fund or retirement package, some new clothes—probably before the old ones wear out. Sum these aspirations over the population and you have pressure for overall growth.

Recently I asked who in my circle at the edge of academia in a progressive college town wants zero personal or professional economic growth. Not soon-to-graduate students looking for the first job. Not immigrants who arrive with almost nothing. Not newlyweds considering starting a family. Not academics building research programs or pursuing tenure. Not college presidents. Not development officers of green non-profit organizations. Not the mayor or city council. And of course not the usual suspects in the business community. I finally concluded that some well-off retirees seem to want zero growth….that’s about it.

2. Watch a TV auto ad and it’s difficult not to suspect—and resent—advertising’s role in fanning the flames of demand. (Mmmmm, a lone car on an otherwise unoccupied road accelerating against the shriek of the engine and the announcer’s deep n’ throaty voice…). But what advertising seduced Pharaoh Ramesses II into carving four 65-foot-tall likenesses of himself from native rock at Abu Simbel ca. 1250 BC? Or the government of Dubai into erecting the 2,722 foot (i.e, 0.52 mile) Burj Khalifa Tower in 2009 AD? I believe essentially all of us are hard-wired to want more of something for some reason. If there is good evidence that advertising is the culprit in overall consumption growth and not just in choosing between spending options, let’s see it.

3. Given the three-millennia separation of the two above construction projects, I think it is wishful thinking to expect Homo sapiens to spontaneously embrace zero growth collectively any time soon.

4. But even if 99+% of us do that, what about the non-cooperators? To the extent that the world is zero-sum (a politically incorrect but applicable description if there really are limits), it takes only a few competitively acquisitive individuals to produce a mess. If the few want more, sooner or later they will destabilize a group of otherwise modest, cooperative individuals. Envy kicks in, or defensive measures to avoid losing. An example of the latter: What to do when the tax bill on your modest abode skyrockets when Ringo Starr and Mick Jagger move in next door (aka the “Aspen effect”)? Try to maintain your modest lifestyle and move 40 miles downriver, or do what it takes to get into the high production/consumption game yourself?

All this brings me back to Monbiot’s bald and bold statement: there is negligible action without effective, broadly felt, implementable…scarcity. In other words, “appropriate scarcity” is not optional; it is necessary. Yes, increasing the price of “bads” is a frequent theme on these pages, but often only as one item in a longish list of principles based on Herman Daly’s powerful writings. Rather, it should be at the top of the list.

There is no question that accomplishing scarcity (for fossil energy, say) by caps and/or taxes is politically, socially, economically, and humanly difficult—a global top-ten red flag. I believe that at the U. S. national level at least, it is feasible. Equity impacts can be minimized by income tax rebates to lower-income households. Other impacts, especially regional, are tougher. In general, moving slowly reduces disruption, but we have scant time. What I hope for is national-level appropriate scarcity of fossil fuels. Done right (a daunting task, to be sure), we can reinforce our own behavior in doing what we (say we) must do to restrain global warming, and have good lives doing it.

Five Myths About Economic Growth

by Brian Czech

Brian CzechMyth #1. It’s economic.

To be economic, something has to be worth more than it costs. Economic activity, per se, is more beneficial than detrimental. Technically speaking, “marginal utility is greater than marginal disutility.”

If you liked a rug, but liked your grandkids more, it wouldn’t be smart to grab the rug out from under them. That’s basic microeconomics. Yet if we look around and reflect a bit, doesn’t it seem like all that economic activity is pulling the Big Rug out from the grandkids at large? Water shortages, pollution, climate change, noise, congestion, endangered species… it’s not going to be a magic carpet ride for posterity.

Growth was probably economic for much of American history. But we have to know when times have changed and earlier policy goals are outdated. In the 21st century, when we’re mining tar sands, fracking far and wide and pouring crude oil by the ton into the world’s finest fisheries, trying to grow the economy even further is looking like a fool’s errand. That’s basic macroeconomics.

Myth #2. Economic growth is often miraculous.

Right now we’ve got the Chinese miracle. We’re supposed to be on the cusp of an Indian miracle. Seems like we already had a more general Asian miracle, having to do with “tigers.”

We’ve had Brazilian, Italian, Greek (yes Greek), Spanish and Nordic miracles. There’s been the Taiwan miracle, the miracle of Chile and even the Massachusetts miracle. Don’t forget the earlier Japanese miracle and more than one historic German miracle.

Let’s hope these aren’t the kinds of miracles they use to determine sainthood. Saint Dukakis, anyone?

No, economic growth was never, anywhere, a “miracle.” It’s never been more than increasing production and consumption of goods and services in the aggregate. It entails an increasing human population or per capita consumption; these go hand in hand in a growing economy. It’s measured with GDP.

Whoop-de-do, right? Maybe Wall Street investors and journalists are an excitable lot, and it’s easy enough to be surprised by a growth rate, but “miracle?”

Myth #3. Growth isn’t a problem for the environment, because we’re dematerializing the economy.

Now that would be a miracle.

Let’s get one thing straight: The economy is all about materials. “Goods,” in other words. Oh sure, services matter too. But the vast majority of services are for purposes of procuring, managing or enjoying our goods.

The biggest service sector, transportation, is responsible for enormous environmental (and social) impacts. Transportation is instructive, too, about the relationship between goods and services. People don’t line up at cash registers demanding random acts of transportation. No, it’s all about moving materials—goods or people—from point A to point B, and moving them economically. Every form of transportation takes energy as well as copious supplies of materials (for vehicles and infrastructure) and space.

With all the talk of “de-materializing,” surely there must be services that transcend the physical, right? What about the Information Economy?

Myth #4. The human economy went from hunting and gathering through agriculture and on to manufacturing, and finally to the Information Economy.

Don’t forget our lesson from the transportation sector: no transportation for transportation’s sake. In the “Information Economy,” what’s all that information going to be used for? If it’s not going to be used in activities such as agriculture and manufacturing (and transportation) how is it going to matter for economic growth?

The fact is, there never was—or always was—an information economy. Pleistocene hunters needed to read mammoth tracks more than we need to read our Twitter feed.

Now when it comes to processing information, the computer was more or less a “revolutionary” invention, like the internal combustion engine was for transportation. But what’s less material about it? Just as today’s hunters have semi-automatic rifles with high-power scopes, they have (material) computers that help them gather information for buying more (material) guns, scouting more (material) terrain and shooting more (material) deer. Anything about that seem greener than before?

Information has proliferated alright, in lock step with the material goods and services it’s been used for. Yet to speak of the “Information Economy” seems like grabbing for some type of economic miracle, and we’ve all seen how cheap miracles are in economic rhetoric.

Myth #5. At least economic growth is egalitarian, because a rising tide lifts all boats.

Once upon a time the rising tide metaphor may have had some merit. In the 21st century—think resource wars, climate change, endang­ered species—it’s more like a rising tide flooding all houses. Which brings us back to Myth #1.

It seems like all the talk of economic growth was overblown, more the result of Wall Street excitement and political rhetoric than sober thought. Maybe what we really want is economic slenderizing.



Preempting a Misleading Argument: Why Environmental Problems Will Stop Tracking with GDP

by Brian Czech

Brian CzechI hate to say I told you so, and could be too dead to do so, so I’ll tell you in advance: One decade soon, environmental problems will stop tracking with GDP.

But the reasons? Well, they probably aren’t what you think, especially if you’ve been drinking the green Kool-Aid.

For decades, big-picture ecologists and eventually the “ecological economists” pointed out the fundamental conflict between economic growth and environmental protection. Every tick of GDP came with the tock of habitat loss, pollution, and, as we gradually realized, climate change. A growing GDP requires a growing human population or a growing amount of goods and services per person. In the American experience of the 20th century, it was easy to see both – population and per capita consumption – spiraling upward, and just as easy to see the environmental impacts reverberating outward. Much of the world saw the same, although in some countries GDP growth was driven almost entirely by population growth.

Unfortunately, a lot of time was spent overcoming fallacious but slick-sounding shibboleths like “green growth,” “dematerializing” the economy, and the “environmental Kuznets curve.” It seemed these were – or easily could have been –designed by advertisers on Madison Avenue, Big Money in general, or economists in their service, to prevent consumers and policy makers from responding rationally to environmental deterioration. Suggestive phrases such as “consumer confidence” spurred the consumer along, buying more stuff to increase the profits of corporations and, in turn, the campaign purses of politicians.

Meanwhile, those who studied, wrote, or simply worried about the effects of economic growth on the environment (and therefore the future economy) were portrayed and marginalized as tree huggers, earth firsters, or, as I once heard them called by a Scotland Yard detective at an intelligence conference, “the great unwashed.”

Some of us had to go so far as debating economists and, shockingly, ecologists who parroted the 1990’s political rhetoric that “there is no conflict between growing the economy and protecting the environment.” I even debated a future president of The Wildlife Society (TWS), who at the time was a biologist employed by the timber industry and a gadfly in TWS attempts to formulate a TWS position on economic growth. After our debate, I was told he was roundly defeated, and in subsequent years he refrained from the win-win rhetoric. (Hopefully it was that ability to reconnoiter with the truth that explains his electoral victory.)

Those of us who recognized the conflict between economic growth and environmental protection won the debates because we were right and we demonstrated it, ad nauseum, theoretically and empirically. We had to study the issue up and down, inside and out, because Big Money had far more resources to try defeating us at every turn. Eventually we published enough articles, organized enough conferences, and won enough debates that today, at least in professional natural resources circles, you’d seem, well… no smarter than a hedgehog if you tried to claim we can have our cake and eat it too.

So it is with ample irony that soon enough, we’ll enter an age where GDP won’t track with biodiversity loss, pollution, climate change, and other indicators of environmental deterioration. Why? Because, at some point during the 21st century and perhaps very soon, there won’t be enough resources left for GDP growth. Just as surely as the conflict between economic growth and environmental protection, there is a limit to growth, and it’s not as far off as the growth polyannas would have you think.

Let’s consider what happens to biodiversity – nonhuman species in particular – in the days beyond growth. Long after GDP growth grinds to a halt, biodiversity will continue declining for two reasons. The first is that many of the environmental effects of earlier GDP growth will be delayed. For example, when a species’ habitat is degraded by a pipeline here and a timber sale there, the species doesn’t instantly disappear. Yet a marginal drop in the rate of reproduction and a marginal increase in the rate of mortality can put the species on a path to extinction just as surely as you pay taxes.

Furthermore, habitat degradation can itself be a drawn-out process. The polar ice caps are on their way out, and polar bears along with them. Yet the ice won’t be gone and the polar bear won’t be extinct for some decades, probably well after GDP has stopped growing. And the polar bear is on the tip of the iceberg, as species en masse may be ushered off the poles as if on some geological conveyor belt running at the speed of climate change.

The second reason biodiversity will continue to decline long after GDP stops growing is because the cessation of GDP growth doesn’t mean corporations and countries will stop trying to grow the GDP. Far from it. As long as economic growth remains the primary policy goal of nations, the environmental impact of pursuing such growth will worsen, because nations will be pulling out all the stops to achieve it. This too is a process already underway; witness the mining of tar sands for exceedingly crude oil.

Yet tough times for the truth await because the next wave of polyannas will be busy perverting the truth from a different angle. Instead of arguing that GDP growth was a benefit to biodiversity  – with the shallow argument that it put more money into conservation programs – they’ll be pointing to the fact that species are declining despite no growth in GDP. “Where’s the correlation,” they’ll ask, “between GDP and biodiversity loss?”

Alas, we’ve been careful all along, as good scientists are, to note that correlation doesn’t prove causality. Likewise, a lack of correlation doesn’t disprove causality. Economic growth – increasing production and consumption of goods and services in the aggregate, entailing a growing population and per capita consumption – has been the limiting factor for wildlife in the aggregate for the broad sweep of Homo sapiens’ reign on Earth. Beginning in the 1930s such growth was measured with GDP, and beginning in the 1970s species endangerment in the U.S. was measured by the length of the list of federally listed threatened and endangered species.

For decades the correlation between GDP and species endangerment was like the correlation between chickens and eggs. A statistic called the R-squared value was even used to measure just how tight. As such, the correlation was simply additional, circumstantial evidence for the conflict between economic growth and biodiversity conservation. It was never essential, though, for it was bloodily evident that the causes of species endangerment were a list of economic sectors, infrastructure, and byproducts. To think it wasn’t the economy causing all that species endangerment was like thinking all that lung cancer in the 70’s had nothing to do with cigarettes.

Now when the Marlboro man stopped smoking, he didn’t stop choking. No, he continued choking, all the way to death, from lung cancer and chronic obstructive pulmonary disease. But hey, in those final non-smoking years, the correlation between cigarettes and cancer cells was non-existent. Would anyone put it past Big Tobacco (the Seven Dwarves come to mind) to use this lack of correlation as evidence that tobacco doesn’t cause cancer?

Didn’t think so.

Well, Big Money – Wall Street, Madison Avenue, K Street too – we’re on to you. We know you’ll claim in decades to come that economic growth is not the cause of environmental deterioration. You’ll use the lack of correlation between GDP and species listings as one of your unscrupulous arguments. And you’ll be as wrong then as you have been heretofore.

Stick that in your pipe and smoke it preemptively.

The Guardian and Monbiot versus Forbes and Worstall

Dalyby Herman Daly

In his Guardian column, criticizing growth as “The Insatiable God,” George Monbiot writes:

Is it not also time for a government commission on post-growth economics? Drawing on the work of thinkers like Herman Daly, Tim Jackson, Peter Victor, Kate Raworth, Rob Dietz and Dan O’Neill, it would investigate the possibility of moving towards a steady state economy: one that seeks distribution rather than blind expansion; that does not demand infinite growth on a finite planet…

It is no surprise that we at CASSE strongly agree with Monbiot. Nor does it come as a surprise that a columnist for Forbes, Tim Worstall, would disagree. What is surprising is that Worstall uses me in support of his position (with which I disagree) and against Monbiot (with whom I agree). How does he manage such a reversal? By conflating growth (quantitative physical increase) with development (qualitative improvement), and claiming that 80% of GDP increase is due to qualitative “growth” (total factor productivity), and is therefore independent of increase in physical resource use–when in reality the “total” factor productivity increase in question is mainly caused by an increase in physical resource throughput. This requires further explanation.

In a previous article, also criticizing Monbiot, Worstall states his position more completely, as quoted below, [my brackets inserted].

Value add [added] is economic growth, not more stuff. And we can take this insight to an extreme as well, that extreme being the steady state economy proposed by Herman Daly. In this world resources are only abstracted from the environment if this can be done sustainably. And we recycle everything of course [not energy or highly dispersed materials]. So, in such a world can we still have economic growth? We have no more access to more stuff to make stuff out of: so is growth still possible? Yes, of course it is. For we can still discover new methods of adding value to those resources that we do have available to us through our recycling. Daly calls this qualitative growth rather than the quantitative growth that we cannot have. [Actually I speak of “qualitative improvement” to emphasize that technology is not a cardinally measurable quantity that can properly be said to grow]. But there’s absolutely no difference at all between this and the more conventional economic descriptions of growth. Qualitative growth is akin to growth through an increase in total factor productivity as opposed to growth via the use of more inputs [only remember that “more inputs” should include natural resources, but does not]. And Bob Solow once pointed out that 80% of the growth in the market economies in the 20th century came from tfp (total factor productivity) growth, not the consumption of more resources. We’re just using different words to describe exactly the same thing here [not really].

Now if this were true we could keep resource throughput constant, avoiding most of the increasing environmental costs of growth, and still have 80% of historical GDP growth. Once matter-energy throughput is stabilized at an ecologically sustainable level we could presumably have significant GDP growth forever with minimal environmental costs, thanks to increasing total factor productivity. I would be happy if that were true, but I am pretty sure that it is not. Nevertheless, if Forbes believes it, maybe they would then endorse a policy of limiting resource throughput (cap-auction-trade or carbon tax), and be content with still significant GDP growth based only on total factor productivity increase? Don’t hold your breath. Worstall explicitly discounts any notion of resource scarcity, so why limit throughput? But, just for good measure, he argues here that even with resource scarcity, technology can, by itself, provide most of our accustomed growth, as it supposedly has in the past.

Worstall’s source for the 80% figure is the “Solow Residual,” which is commonly misinterpreted as a measure of total factor productivity. As calculated, it is a measure of “two-factor” productivity, the two factors being labor and capital. The Cobb-Douglas production function that underlies this calculation omits natural resources, the classical third factor. This means that it cannot possibly be an accurate analytical representation of production. It is like a recipe that includes the cook and the oven, but omits the list of ingredients.

Value added has to be added to something, namely natural resources, by something, namely labor and capital. The cook and the oven add value to the ingredients, but nothing happens without the ingredients. Our empty-world economic accounting attributes all value to labor and capital, and treats natural resources in situ as superabundant free gifts of nature. But in today’s full world, resources are not only scarce but have become the limiting factor. Leaving the limiting factor out of the analysis makes the Cobb-Douglas production function not only incomplete, but also actively misleading.

Nevertheless, Worstall’s 80% figure comes from respected economists who have used the Cobb-Douglas production function in a statistical correlation–an exercise to see how much of increased production can be statistically explained by increases in labor and capital. The residual, what is not explained by labor and capital increase, is attributable to all causes other than labor and capital, including, for example, technology improvement and increased material and energy throughput (natural resource use).

A large residual indicates weak explanatory power of the theory being tested–in this case the Cobb-Douglas theory that production increase is due only to capital and labor increase. But instead of being embarrassed by a large unexplained residual, some economists were eager to “explain” it as an indirect measure of technological progress, as a measure of improvement in total factor productivity. But is technology the only causative factor reflected in the residual? No, there are surely others, most especially the omitted yet rapidly increasing flow of natural resources, of energy and concentrated minerals. The contribution of energy and materials from nature to production is also part of the residual, likely dwarfing technological improvement. Yet the entire residual is attributed to technology, to total factor productivity, or more accurately “two-factor” productivity, in the absence of natural resources, the classical third factor.

As the natural resource flow greatly increases, and capital and labor transform that growing resource flow into more products, then of course the measured productivity of capital and labor increases. This increased “total” factor productivity, due mostly to increase in the ignored factor of natural resources, is then appealed to as evidence of the unimportance of natural resources, given the “empirical finding” that total factor productivity improvement (technology) “explains” so much of the observed increase in production. This reasoning is clearly specious. It is the increased resource use that explains the increase in total factor productivity (i.e. two-factor productivity), which cannot then be used as a reason to discount the importance of its own cause, namely an increased flow of natural resources. Indeed, the unimportance of natural resources could not possibly be an empirical finding of any statistical analysis based on the Cobb-Douglas production function, because that function assumes the unimportance of natural resources from the beginning by omitting them as a factor of production. This is a big confusion and Worstall is not the only one misled by it.

In conclusion, I think the Guardian and Monbiot’s position is not in the least weakened by the criticism from Forbes and Worstall, but that reliance on the Cobb-Douglas production function should certainly be weakened.

The Kingdom of God: A Steady State Economy?

Editor’s Note: the below has been modified and cross-posted from Mission Catalyst, Issue 4, 2014

by Brian Czezh

BrianCzechI’ll never forget the privilege, maybe five years ago, of addressing a small, interdenominational group of faith leaders in Washington, DC. They’d asked me to talk about limits to economic growth and to give a synopsis of the steady state economy as an alternative to growth. We then went around the group, perhaps eight in all, and discussed the issues. One pastor, deep in thought, summarily theologized, “The steady state economy; now that’s the Kingdom of God.” I can hear it like it was yesterday.

The rest of the conversation isn’t quite so vivid. As a long-time advocate of the steady state economy, maybe I got too excited to focus, thinking of the possibilities with God on our side! Also, it’s not like the pastor (Episcopal as I recall) had a full-fledged steady-state theology developed, at least at the time. Macroeconomics is not something he or the rest of the group had thought much about, but they’d definitely taken an interest in protecting the environment, or “caring for Creation” as some like to say.

And yet, if there is a place for common sense in theology, there is plenty to suggest the pastor was right on track. Would anyone be driving a Hummer in the Kingdom of God? Or building a McMansion? Wearing a fur coat? Presumably the trappings of conspicuous consumption would seem more befitting of…you know, that other place.

The pastor knew something was awry with the quest for ever more. Striving for more and more stuff isn’t caring for Creation. Think, for example, what it means to life on earth–all of Creation–with economic growth as the primary policy goal of so many nations. If you were to list the causes of species endangerment, it would read like a Who’s Who of the economy. A proliferation of all such activities is hardly wise husbandry.

But to really assess the relationship or relevance of economic growth to the Kingdom of God, and prior to any thorough theological assessment, we must have a solid grasp of exactly what economic growth is. It’s not enough to make vague references to Hummers or ask, “What would Jesus drive?”

In textbook terms, then, economic growth is increasing production and consumption of goods and services in the aggregate. It requires increasing human population and/or per capita consumption, and almost always entails both. The metric used to measure economic growth is GDP, or gross domestic product.

The phrase “in the aggregate” is actually quite important. Sometimes we hear confusing talk about “green jobs” and even “green growth.” It may well be that replacing oil wells with vast arrays of solar panels and wind towers provides different jobs than we had in the past and doesn’t result in as many carbon emissions. But that one development–replacing fossil fuels with renewable energy–is hardly economic growth. It’s a sectoral readjustment that may or may not accompany economic growth: increasing production and consumption of goods and services in the aggregate. If we do manage to generate enough power from renewable sources to have even more agriculture, mining, logging, ranching, milling, manufacturing, and service sectors all the way from transportation to entertainment, what happens to all the wildlife habitat?

The fact is, in the push for GDP growth, God’s creatures suffer. To put it in the technical terms of ecological economics, as the human economy grows, natural capital is reallocated out of the economy of nature and is converted into consumer goods and manufactured capital. How is that caring for Creation? The steady state economy–stabilized population and per capita consumption, in simplest terms–means a stable environment for all the other creatures.

A growing number of citizens and activists are taking note that pulling out all the stops for GDP growth isn’t making man any happier. It has even become popular in sustainability circles to discredit GDP, as if it’s a meaningless indicator. However, attacking GDP is like shooting the messenger, or shooting the metric to be more accurate. Yes, it is perfectly true and important to realize that GDP is not a measure of wellbeing, but GDP is a solid indicator of the size of an economy. Despite all the talk of “green growth,” real GDP (“real” meaning adjusted for inflation) cannot increase without more impact on the environment.

Here is where a bit of theology seems to dovetail nicely with biology. The Bible says, “All flesh is grass” (Isaiah 40:6). While the direct theological implication seems more about the insignificance of man on Earth, relative to God, this verse is more than mere metaphor. The fact is that the foundation of the “economy of nature,” or Creation, is indeed plants, or “grass” in the words of Isaiah. No plants, no animals: no grass, no flesh.

This truth happens to be a central pillar of ecology. Every good ecology textbook will have a thorough discussion of “trophic levels.” Living beings in nature start with the plants at the base, literally and figuratively. Plants are called “producers” because they produce their own food in the process of photosynthesis. All other beings are “consumers” of some type. Primary consumers eat plants directly; secondary consumers eat the primary consumers. Primary consumers are often called herbivores; secondary consumers are “predators.” These are the three basic trophic levels: producers, primary consumers, and secondary consumers.

Meanwhile the book of Genesis says that God created mankind in his own image. It seems fitting, then, that the economy of man is like a microcosm of Creation, or the economy of nature. Man’s economy has producers (agricultural and extractive sectors), primary consumers (manufacturing), and secondary consumers including the purchasers of consumer goods and services in the market.

In order to have increasing production and consumption of goods and services in the aggregate, there must be more surplus produced at the base of the trophic structure. In other words, there must be more agricultural and extractive activity to free the hands for the division of labor into manufacturing, services, and “green” jobs. More and more money spent means more and more environmental impact; more erosion of the Creation.

Finally, no discussion of a steady state economy can be complete without the issue of population. Hopefully common sense suffices for understanding how we cannot have perpetual population growth on a finite planet. We humans aren’t like angels on the head of a pin. We have minimum material and energy requirements for survival.

My theology is amateurish at best, but isn’t the Kingdom of God supposed to lead to the final Kingdom of Heaven? It would seem that, at some stage, after life on Earth, the Kingdom of Heaven comes to its fruition of souls. So perhaps our good pastor was thinking ahead–way ahead–on the population front! Meanwhile, doing the best we can at caring for Creation entails serious efforts toward stabilizing our population as well as tempering our consumption.

It’s not easy advancing the steady state economy as the sustainable alternative to economic growth. If money is the root of all evil, we have a nasty force working against us: Big Money! The corporate forces in the world don’t want us talking about limits to growth or a steady state economy. They want governments pulling out all the stops for GDP growth.

On the other hand, they don’t exactly have the ultimate Commander in Chief on their side!

An Economics Fit for Purpose in a Finite World

by Herman Daly

Herman DalyCausation is both bottom-up and top-down: material cause from the bottom, and final cause from the top, as Aristotle might say. Economics, or as I prefer, “political economy,” is in between, and serves to balance desirability (the lure of right purpose) with possibility (the constraints of finitude). We need an economics fit for purpose in a finite and entropic world.

As a way to envision such an inclusive economics, consider the “ends-means pyramid” shown below. At the base of the pyramid are our ultimate means, low entropy matter-energy–that which we require to satisfy our purposes–which we cannot make, but only use up. We use these ultimate means, guided by technology, to produce intermediate means (artifacts, commodities, services, etc.) that directly satisfy our needs. These intermediate means are allocated by political economy to serve our intermediate ends (health, comfort, education, etc.), which are ranked ethically in a hierarchy by how strongly they contribute to our best perception of the Ultimate End. We can see the Ultimate End only dimly and vaguely, but in order to ethically rank our intermediate ends we must compare them to some ultimate criterion. We cannot avoid philosophical and theological inquiry into the Ultimate End just because it is difficult. To prioritize logically requires that something must go in first place.

Ultimate Political Economy

The ends-means pyramid or spectrum relates the basic physical precondition for usefulness (low entropy matter-energy) through technology, political economy, and ethics, to the service of the Ultimate End, dimly perceived but logically necessary. The goal is to unite the material of this world with our best vision of the good. Neoclassical economics, in neglecting the Ultimate End and ethics, has been too materialistic; in also neglecting ultimate means and technology, it has not been materialistic enough.

The middle position of economics is significant. Economics in its modern form deals with the allocation of given means to satisfy given ends. It takes the technological problem of converting ultimate means into intermediate means as solved. Likewise it takes the ethical problem of ranking intermediate ends with reference to a vision of the Ultimate End as also solved. So all economics has to do is efficiently allocate given means among a given hierarchy of ends. That is important, but not the whole problem. Scarcity dictates that not all intermediate ends can be attained, so a ranking is necessary for efficiency–to avoid wasting resources by satisfying lower ranked ends while leaving the higher ranked unsatisfied.

Ultimate political economy (stewardship) is the total problem of using ultimate means to best serve the Ultimate End, no longer taking technology and ethics as given, but as steps in the total problem to be solved. The total problem is too big to be tackled without breaking it down into its pieces. But without a vision of the total problem, the pieces do not add up or fit together.

The dark base of the pyramid is meant to represent the fact that we have relatively solid knowledge of our ultimate means, various sources of low entropy matter-energy. The light apex of the pyramid represents the fact that our knowledge of the Ultimate End is much less clear. The single apex will annoy pluralists who think that there are many “ultimate ends.” Grammatically and logically, however, “ultimate” requires the singular. Yet there is certainly room for plural perceptions of the nature of the singular Ultimate End, and much need for tolerance and patience in reasoning together about it. However, such reasoning together is short-circuited by a facile pluralism that avoids ethical ranking of ends by declaring them to be “equally ultimate.”

It is often the concrete bottom-up struggle to rank particular ends that gives us a clue or insight into what the Ultimate End must be to justify our proposed ranking.

As a starting point in that reasoning together, I suggest the proposition that the Ultimate End, whatever else it may be, cannot be growth in GDP! A better starting point for reasoning together is John Ruskin’s aphorism that “there is no wealth but life.” How might that insight be restated as an economic policy goal? For initiating discussion, I suggest: “maximizing the cumulative number of lives ever to be lived over time at a level of per capita wealth sufficient for a good life.” This leaves open the traditional ethical question of what is a good life, while conditioning its answer to the realities of economics and ecology. At a minimum, it seems a more convincing approximation to the Ultimate End than today’s impossible goal of “ever more things for ever more people forever.”

Three Limits to Growth

by Herman Daly

Herman DalyAs production (real GDP) grows, its marginal utility declines, because we satisfy our most important needs first. Likewise, the marginal disutilitiy inflicted by growth increases, because as the economy expands into the ecosphere we sacrifice our least important ecological services first (to the extent we know them). These rising costs and declining benefits of growth at the margin are depicted in the diagram below.

3 Limits Graph

From the diagram we can distinguish three concepts of limits to growth.

1. The “futility limit” occurs when marginal utility of production falls to zero. Even with no cost of production, there is a limit to how much we can consume and still enjoy it. There is a limit to how many goods we can enjoy in a given time period, as well as a limit to our stomachs and to the sensory capacity of our nervous systems. In a world with considerable poverty, and in which the poor observe the rich apparently still enjoying their extra wealth, this futility limit is thought to be far away, not only for the poor, but for everyone. By its “non satiety” postulate, neoclassical economics formally denies the concept of the futility limit. However, studies showing that beyond a threshold self-evaluated happiness (total utility) ceases to increase with GDP, strengthen the relevance of the futility limit.

2. The “ecological catastrophe limit” is represented by a sharp increase to the vertical of the marginal cost curve. Some human activity, or novel combination of activities, may induce a chain reaction, or tipping point, and collapse our ecological niche. The leading candidate for the catastrophe limit at present is runaway climate change induced by greenhouse gasses emitted in pursuit of economic growth. Where along the horizontal axis it might occur is uncertain. I should note that the assumption of a continuously and smoothly increasing marginal cost (disutility) curve is quite optimistic. Given our limited understanding of how the ecosystem functions, we cannot be sure that we have correctly sequenced our growth-imposed sacrifices of ecological services from least to most important. In making way for growth, we may ignorantly sacrifice a vital ecosystem service ahead of a trivial one. Thus the marginal cost curve might in reality zig-zag up and down discontinuously, making it difficult to separate the catastrophe limit from the third and most important limit, namely the economic limit.

3. The “economic limit” is defined by marginal cost equal to marginal benefit and the consequent maximization of net benefit. The good thing about the economic limit is that it would appear to be the first limit encountered. It certainly occurs before the futility limit, and likely before the catastrophe limit, although as just noted that is uncertain. At worst the catastrophe limit might coincide with and discontinuously determine the economic limit. Therefore it is very important to estimate the risks of catastrophe and include them as costs counted in the disutility curve, as far as possible.

From the graph it is evident that increasing production and consumption is rightly called economic growth only up to the economic limit. Beyond that point it becomes uneconomic growth because it increases costs by more than benefits, making us poorer, not richer. Unfortunately it seems that we perversely continue to call it economic growth! Indeed, you will not find the term “uneconomic growth” in any textbook in macroeconomics. Any increase in real GDP is called “economic growth” even if it increases costs faster than benefits.

Economists will note that the logic just employed is familiar in microeconomics—marginal cost equal to marginal benefit defines the optimal size of a microeconomic unit, be it a firm or household. That logic is not usually applied to the macro-economy, however, because the latter is thought to be the Whole rather than a Part. When a Part expands into the finite Whole, it imposes an opportunity cost on other Parts that must shrink to make room for it. When the Whole itself expands, it is thought to impose no opportunity cost because it displaces nothing, presumably expanding into the void. But the macro-economy is not the Whole. It too is a Part, a part of the larger natural economy, the ecosphere, and its growth does inflict opportunity costs on the finite Whole that must be counted. Ignoring this fact leads many economists to believe that growth in GDP could never be uneconomic.

Standard economists might accept this diagram as a static picture, but argue that in a dynamic world technology will shift the marginal benefit curve upward and the marginal cost curve downward, moving their intersection (economic limit) ever to the right, so that continual growth remains both desirable and possible. However, the macroeconomic curve-shifters need to remember three things. First, the physically growing macro-economy is still limited by its displacement of the finite ecosphere, and by the entropic nature of its maintenance throughput. Second, the timing of new technology is uncertain. The expected technology may not be invented or come on line until after we have passed the economic limit. Do we then endure uneconomic growth while waiting and hoping for the curves to shift? Third, let us remember that the curves can also shift in the wrong directions, moving the economic limit back to the left. Did the technological advances of tetraethyl lead and chlorofluorocarbons shift the cost curve down or up? How about nuclear power? Adopting a steady state economy allows us to avoid being shoved past the economic limit. We could take our time to evaluate new technology rather than letting it blindly push growth that may well be uneconomic. And the steady state gives us some insurance against the risks of ecological catastrophe that increase with growthism and technological impatience.

Transformative Common Sense in Vermont

by Eric Zencey

Eric ZenceyChances are that when you hear the phrase “Comprehensive Economic Development Strategy,” you don’t immediately think of dramatic change in the established political-economic order of things. The words don’t seem revolutionary. They certainly don’t call to mind images of furtive guerillas toting rifles or of throngs in public squares using chains and ropes to topple statues. Chances are equally good that unless you hang out with economic development officers or land use planners, you’d have a hard time rounding up a dozen people who’d sit still long enough to hear what a CEDS is, let alone why it might be of interest to them. But despite the dry name, the document recently released by Vermont’s Department of Commerce and Community Development portends a quiet, far-reaching revolution in governance in the Green Mountain State–and perhaps on a larger stage.

The potential for this enormous change is signaled in a short, clear statement from the report’s Executive Summary:

…This CEDS sets out a unique, overarching goal: it proposes to not only grow jobs and wages and increase our Gross Domestic Product, but also to improve the Genuine Progress Indicator (GPI)…by 5% over baseline over the next five years.

With this language, Vermont becomes the first state to make explicit use of an alternative indicator in setting goals for economic development. The commitment to use the GPI in this way places Vermont in the forefront of a growing national movement to integrate the GPI into social and economic policy. Because GDP-based economic development is so wrong-headed, this commitment is a matter of common sense; and yet, because GDP-based economic development is so deeply woven into the substance and texture of our political economy, using basic common sense here is a powerfully transformative act.

The faults and flaws of GDP as a measure of economic progress are well known and don’t need to be repeated in detail here. It was never intended to serve as a measure of economic wellbeing, and one of the largest problems in using it for that purpose is that it doesn’t subtract environmental damage as a cost of economic development. Instead, it simply ignores these losses as externalities–until and unless money is spent to correct them, at which time the remediation of the cost is transformed, as if magically, into an apparent economic benefit. (This is a macroeconomic instance of what is generally called the broken window fallacy.) Negative environmental externalities occur when economic activity exceeds one of the planet’s local, regional, or global source-and-sink limits and thereby imposes harm, damage, cost or loss on innocent third parties–people who neither produce nor consume the goods whose production damages the environment. (Traditional economists don’t talk of “innocent” third parties when they discuss externalities, but the morally charged language is appropriate. Why should it be acceptable for profit-seekers to impose uncompensated loss on the general public?)

Because these externalities have their origin in ecosystem limits, and GDP treats the externalities as if they didn’t exist, it’s fair to call GDP an infinite planet statistic. Brian Czech has argued recently that what GDP measures best is environmental impact. While GDP isn’t a perfect measure of environmental impact—some of the things we consume cause less environmental damage per dollar than others—it seems a decent proxy, since in general it’s true that the larger the economy in GDP terms, the larger its environmental impact.

In contrast, the Genuine Progress Indicator subtracts environmental and other costs from the ledger, giving a more accurate bottom line. In doing so, GPI applies the principles of double-entry bookkeeping to the economy as a whole. The invention of double entry bookkeeping was a crucial to the growth of capitalism; a business can’t stay in business for long if its managers have no idea how its debits stack up against its credits, how its costs compare to revenues. And what’s true at the micro scale is true, in this instance, at the macro scale: because GDP systematically miscounts costs as benefits, we’re about to go environmentally broke–the entire economy may go out of business as climate change and loss of biodiversity bring dramatic, civilization-threatening change.

There is nothing in the Genuine Progress Indicator that says, explicitly, “there are ecological limits to economic growth.” But because it subtracts environmental costs from economic benefits, the GPI is a finite planet indicator that will, if implemented accurately, lead policy makers to this realization. Consistent, accurate compilation of the GPI will make clear that for any given ecosystem, at some point economic growth that is rooted in that system costs more in ecosystem service losses than it brings in economic gains.

This means that there are limits to the amount of economic production the planet’s ecosystems can support. Obviously, that fact has implications for economic development and the policies that promote it. Foremost among those implications is the necessity of abandoning the traditional “jobs and GDP” focus of development policy. As noble as it may be to aim to assure every aspiring worker the dignity of useful work, and as comforting as it is to think that we can continually add to our national stock of wealth by perpetually growing our national income, neither goal can be accomplished forever (or even, arguably, in the near term) through policies that take GDP growth or job growth as their sole and solitary focus. A commitment to perpetual full employment that is not also connected to an effort to limit population growth is at bottom a commitment to perpetual economic growth, a chimerical ideal. And because GDP so badly miscounts costs and benefits, failing to keep them separate, any policy effort that aims solely at increasing GDP is destined to be fatuous.

In announcing a development goal that is couched in terms of the GPI, Vermont has put itself on a path that will lead away from traditional “jobs and GDP” thinking–though the divergence of the two paths is not yet fully clear to policy makers. (Recall that the CEDS document aims not only at improving the GPI but also to “grow jobs and wages and increase…GDP.”) No doubt many of the legislators and policy makers who supported the state’s adoption of GPI as a better accounting system did not and would not embrace the notion that there are limits to economic growth. But the contrast between new-think and old-think, between finite and infinite planet thinking, between promoting sustainable economic activity and continuing the “growth forever, business-as-usual” mindset can only become clearer with time. As awareness of the GPI and its precepts filters into state decision-making processes, Vermont will find itself increasingly led to develop in ways that are sustainable and that do not damage the delivery of ecosystem services to its citizens. That kind of development will give the state a competitive edge in the region and nation, as it lays a foundation for the sustainable, post-petroleum, post-perpetual-growth economy that must come to the entire planet, in one version or another, sooner or later. (After all, the one thing you can know about an unsustainable system is that it won’t last.) Vermont’s policy use of the GPI is transformative common sense that will make that inevitable transition smoother and less disruptive for all Vermonters.

Gross Domestic Problem: Don’t Shoot the Measurement

by Brian Czech

BrianCzechA battle is brewing on the outskirts of the general public. A rising tide of quixotic activists is trying to overthrow a time-tested American institution. Like the Battle in Seattle, where the IMF was put on public trial, this new struggle will get a lot of attention, but the institution will remain.

The “institution” in this case is a metric: GDP, or Gross Domestic Product. But GDP isn’t any old metric, like widgets assembled or the price of potatoes. GDP is thoroughly institutionalized at the center of our domestic policy arena. When fiscal and monetary policies are crafted, each is judged according to the likely effects on GDP. If something will increase GDP, it must be good and will likely be adopted. GDP growth is the king of policy goals.

The central logic of pursuing GDP growth is “a rising tide lifts all boats.” As long as GDP continues to grow, it is mathematically possible to have more jobs and increase the amount of GDP available per person. In other words, the “standard of living” can increase with GDP.

The rising tide logic made perfect sense during most of the 20th century, when there was a lot of open water and plenty of boat-building material. But such is not the case in the 21st century. Growing the GDP entails population growth or growth in consumption per person; usually both. Trying to grow the GDP these days causes as many problems as it solves. Biodiversity loss, climate change, and pollution are some of the obvious ones. Noise, congestion, and stress are too. It doesn’t look like GDP growth increases the standard of living after all, unless your idea of living standards is particularly anal.

A more nuanced problem is that GDP growth is addictive, kind of like NFL football or World Cup soccer. It has societies and governments all over the world scrambling like hamsters to keep “the score” from shrinking. Crazy things are done in the name of GDP growth: huge rivers are dammed, Keystone pipelines are built, Supreme Courts kick people out of their homes. (Remember Kelo vs. New London?) A society hell-bent on GDP growth is like a junkie doing whatever nasty thing it takes for the next high, rather than doing the right thing for himself and his family.

Yet the realization is gradually spreading that GDP growth can’t continue forever. This reality is causing societal angst and discomfort. For many, especially in the economics profession and business world, the response is denial. “The world can, in effect, get along without resources” is how Robert Solow, the Nobel prize-winning economist, put it.

But among those with their feet firmly on the ground, seeing the limits to growth materialize, the responses aren’t always prudent either. One such response has been to shoot the measurer, or to be more metaphorically accurate, to shoot the measurement of GDP. The politics of this makes for some exceptionally strange bedfellows. From tree-hugging Earth Firsters to staid Austrian-school economists to think tanks funded by the Rockefeller Brothers fund, performing an exorcism of GDP from the spirit of our political economy is all the rage.

The motives of the GDP antagonists differ wildly, reminiscent of the NRA joining the ACLU to fend off the NSA. Pro-growth, free-market economists don’t like government getting any credit for anything, and GDP calculations include government spending, so GDP must be an evil spirit. On the other end of the spectrum, no-growth proponents who see the government as a force to defeat the pro-growth capitalists (and economists) think… something quite odd. They think that, if we refuse to even acknowledge GDP, we’re less likely to be obsessed with its growth, and we can focus more on healthier goals such as better education and healthcare.

It’s shoddy logic at best. It’s akin to an alcoholic thinking, “If I don’t count those beers I drink, I’m not as likely to drink so many. Then I can focus more on my book-learning and health.”

Shall we have a toast? Let’s drink to not counting those beers!

No, the fact is that the alcoholic needs to count those beers more than ever. The diabetic needs to monitor that blood sugar. The obese patient needs to monitor that scale. You get the picture: As our economy exceeds the capacity of the planet to sustain us and future generations, we need to monitor the size of our economy more closely than ever. And there is no better measurement of the size of our economy than GDP.

Due to the fundamental structure of the economy, the size of the economy – as measured by GDP – is a perfectly valid indicator of environmental impact. Agricultural and extractive sectors form the base, which must expand to support the growth of manufacturing and service sectors – yes even the “information economy.” This structure, which is the closest thing in economics to an inescapable law of physics, gives us the “trophic theory of money,” which says that the level of expenditure (GDP, in other words) is proportionate to environmental impact including such tangibles as biodiversity loss, climate change, and pollution in the aggregate.

Those who think technological progress can somehow decouple GDP growth from environmental impact haven’t thought hard enough about the relationship between technological progress and the GDP growth that was based on pre-existing levels of technology. The two go hand in hand, which again in the 20th century was a fine thing. The two going hand in hand in the 21st century tells us nothing except that technological progress cannot reconcile the conflict between economic growth and environmental protection.

So let’s not shoot the measurer or the measurement. Let our friends in the Bureau of Economic Analysis calculate GDP as consistently as they’ve done for over 80 years. They perform a valuable service, and GDP is an invaluable metric. Instead of shooting it, let’s help to ensure the appropriate attitude toward ever-growing GDP: that is, a growing sense of alarm and a concomitant determination to stabilize the size of this economic ship before it sinks as surely as the Titanic.
