The Limits To Complexity

The following essay was written by Ashvin Pandurangi, a law student at George Mason University. In it, he tackles the topic of our present predicaments in the light of complexity, a topic of course first and famously put center stage by Professor Joseph Tainter in the 1980's (listen to a fascinating recent Tainter interview here).

The Limits To Complexity


A Fundamentally Flawed Perspective

The current U.S. administration has its eyes dead set on more fiscal stimulus and/or monetary easing to counter the ever-growing threat of severe deflation on the horizon. Despite the trillions added to our Treasury and Fed’s balance sheets in 2008-09, the 2010 Q2 GDP number is anemic (1.6%) even when it can be trusted as accurate. Most of the ever-optimistic (and late-to-reality) American investment banks have significantly revised their estimates for 2010 H2 GDP down to around 2%, while most serious analysts agree it will be closer to a negative print. Existing and New Homes sales in July 2010 have experienced record declines in the absence of government subsidies (~27% and ~35%).

Unemployment remains significantly higher than reported, as U-6 hovers at 17% and shows no signs of improving (includes workers who have given up looking for jobs – can we blame them when there are 5 workers for every job?). Close to 40 million Americans are on food stamps, 5 million on emergency unemployment benefits and 500,000 recently filed initial jobless claims in one week. Equity outflows from institutional investing firms have continued for months unabated and have totaled over $50 billion year-to-date. Confidence indicators have been gradually deteriorating among consumers and businesses, and that does not bode well for the largest pyramid scheme in human history.

On the other side of the American political divide, conservative Republicans who claim to identify with tea party activists argue for fiscal austerity and less government regulation/intervention in the economy. Leaving aside the glaring hypocrisy of these politicians (many of them contributed greatly to a doubling of the federal debt and expansion of subsidies/entitlements from 2000-08), there are still several other troubling aspects to their alleged views. One of these aspects is the gross injustice of asking a majority of the population to forego promised entitlements and economic relief after we already decided to bail out a small minority of the population.

Two wrongs don’t make a right, but neither does one wrong and a humiliating slap to the collective face. Another is the fact that many of these politicians have no idea what their policies really entail for the economy. As explained in sections below, it’s not as simple as cutting deficits, letting the free market take over and watching the flowers bloom as the sun shines on a new day in America. There will be a chaotic descent into economic depression and a need for governments to help mitigate the damages and promote structural reforms to the debt-based, fossil fuel economy. Speaking of fossil fuels, these politicians and pundits also naively ignore the critical issues of climate change and peak oil production or assume unregulated free(-falling) markets can eventually solve these issues on their own, without much negative impact to the economy.

The main critique of this essay is that the viewpoints described above have a fundamentally flawed perspective on our current economic predicament. Whether it’s the left or the right, the free marketers or the socialists or many of the shades in between, the mainstream consensus is one of desperate hope for a rapid return to continuous economic growth, low unemployment, relatively cheap finance and rapid consumption of natural resources. More generally, there is an insatiable lust for maintaining complexity in our modern systems of economic exchange and social organization. Of course, this critique is not true of everyone in the mainstream camps described above, but I find it telling that we rarely (almost never) hear the word “complexity” or phrase “peak” anything mentioned in their bitter debates.

Complexity Analogized

One of the most familiar complex systems to Americans is our country's inter-connected network of highways, which allow the interstate travel of goods and capital (humans included). This flow mainly passes through large urban centers that act as hubs for the rest of the network. We could have built these highways and then left drivers to their own decisions on how to use them, but it became clear that completely unregulated networks of travel imposed unacceptable safety/economic risks for our society. In fact, the potential risks and instabilities of such a system were so large that it may have completely broken down before it led to any significant gains. Instead, we resorted to licensing procedures and various vehicle and highway regulations.

People who wish to take advantage of the highway system must first be taught the basics of operating a vehicle and pass a test of their knowledge. They must also follow the regulations imposed on them (speed limits, traffic lights, signs, etc.) and maintain their vehicles (annual inspections) under threat of economic or physical punishment. There is also the requirement that drivers get insured for accidents so that they will not pass off the cost onto taxpayers or innocent victims. All of the above are top-down policies used to manage a complex system containing numerous interacting variables. Many motor vehicle accidents still happen and many people still die each year because of them, but we have decided to put up with that level of instability in return for the efficiencies created. One can argue that even this somewhat balanced system is long-term unsustainable and destructive (especially considering environmental costs), but at least it has yet to fall apart.

Now we can compare the highway system to the significantly more complex, expansive networks of the global economy and specifically the financial markets that make international trade/investment possible on a global scale. Individual countries (or even major cities in the larger state economies) can be considered the central hubs for much of these economic flows. The flows are greatly aided by the use of financial instruments (bonds, letters of credit, etc.) that are much easier to “manufacture” than the goods/services being exchanged, though they may be harder to comprehend. Financial markets provide humanity with a method for pulling future energy/resources (real or perceived) into the present, which allows for greater levels of present-day trade, consumption and investment. The key point here is that these sources of energy/resources may not exist and/or be easily utilized in the much depended on future. A system can only retain or evolve its complexity as long as new energy/resource inputs are provided to it in ever-larger doses.

The credit bubble over the last few decades reflects an exponential growth of complexity in the global economy (and in all of human civilization as a result). In 1929 at the beginning of the Great Depression, the U.S. private debt to GDP ratio was about 150%. Fast forward to 2007, and we have more than doubled that ratio to a staggering 300%+ and many other countries have also followed in our misallocated footsteps (housing bubbles have developed in Canada, China, India, Australia and many Euro-zone countries to name a few). America could rightfully be accused as the primary driver of this bubble, since we have the global reserve currency and much of the debt incurred by people in other countries was denominated in dollars. We owe much of that status to our bloated military-industrial complex and reckless/malicious expansionist policies (the U.S. has 700+ military bases established around the world).

We also see that public debt levels in the global economy have reached levels much higher than those in the 1930s. The public debt to GDP ratio for the U.S. is either 90% (total national debt), 150% (total debt including GSE debt) or 900% (total debt including GSEs and unfunded entitlement obligations), with the latter two being the most accurate, which is probably why the Chairman of the Joint Chiefs of Staff (Mike Mullen) called it the “single biggest threat” to national security. As a result of this debt-fueled private and public spending spree, economic activity has reached a very large scale and scope around the globe and many new inter-dependencies have been created between countries, corporations and individuals. American people have increasingly found themselves relying on megalithic grocery/retail stores to secure supply of food and consumer goods from across the planet, while American corporations rely on labor, parts and services from many different countries.

Several global institutions have been designed to impose a top-down management structure for these complex economic and political relationships. Similar to state and federal regulatory bodies within a country, they are commissioned to “alleviate” inherent instabilities that arise from the operations of a complex, dynamic system. Needless to say, they have predictably failed at this goal even more miserably than the central governments of nation-states. The global credit (complexity) bubble is currently in the process of imploding due to its inherent Ponzi dynamics.

As is the case with any Ponzi scheme, it can only be maintained if new entrants continue buying into it, but most economic actors (individuals, corporations and governments) are now saturated with debt as their cash flows have stagnated or declined (they can barely afford to pay down existing debts, let alone take on new debt). Multiple claims to existing real wealth are destroyed as the bubble implodes and our societal systems, which are mal-adapted to credit contraction and slow/negative growth, begin to experience immense destructive pressure. This process is quite evident in the Euro-zone, where entire “sovereign” states are quickly descending into utter insolvency despite the newly-formed credit facilities of the ECB and IMF (the latter recently decided to eliminate the borrowing cap on their facility in a final act of desperation).

We must also keep in mind the role of feedback loops when discussing complex dynamics, since variable elements of a system constantly interact with each other in unexpected, but also generally predictable ways. As a system’s complexity increases, negative feedbacks provide a certain level of stability and the system can self-organize at a relatively stable equilibrium. However, at peak levels of complexity the negative feedbacks are overwhelmed by instabilities that have formed, and on the way down predictable positive feedbacks are the hallmarks.

In a complex economic system that has reached peak financial activity, debt destruction from pay-downs and defaults leads to falling aggregate demand, suppressed prices, shrinking profit margins, increased unemployment, which further reduces demand and suppresses prices. American states on the brink of bankruptcy are all too familiar with these positive feedback loops, as their high rates of unemployment have led to low tax revenues, leading to spending cuts/tax hikes, leading to lower incomes and higher unemployment, leading to even lower tax revenues and massive fiscal deficits. These are just two of many positive feedback loops which occur in a debt deflation, and it is important to remember there are other factors involved and cross-interactions between separate loops within a system. They are also not limited to just the economy but eventually find their way into politics and societal trends at large.

The Devil’s in the Details

Neo-Keynesians’ House of Cards

President Obama’s administration, with the aid of various academics (such as Paul Krugman) and media pundits (such as those on CNBC), have embarked on a mission to restore “business as usual” economic growth through the use of fiscal stimulus, “loose” monetary policy and direct government intervention in the economy. The American Reinvestment Recovery Act allocated about $820 billion to various local governments and companies in an effort to create jobs. What they don’t tell you about the ARRA is how much of that money, as a matter of necessity, is wasted in bureaucratic institutions that distribute and keep track of the money as it is funneled down to economic actors.

Much of the money also goes to funding extremely misguided projects, such as tax credits for homebuyers that incentivized the construction of new homes when there is already a year’s worth of excess supply. Sometimes the money goes to fund the repair of roads that don’t even need any repair, as I have personally witnessed in my own community. New estimates have made clear that it is unlikely more than 1 million jobs were created by the ARRA stimulus, which amounts to $820,000 per job, some of which were not even productive for the general economy. Debt saturation and peak complexity is the primary reason why every additional debt-dollar spent into the economy produces significantly less than a dollar of productive economic value. The most that can be said by the administration about this fiscal stimulus is that it redistributed wealth from working class taxpayers to…well, other working class taxpayers, but also REITs (real estate investment trusts) and banks, and a bunch of money was lost in the process.

The loose monetary policies being used include keeping the federal funds rate and discount rate at close to 0% (rate at which banks can borrow from each other and the Fed) and purchasing debt assets such as mortgage-backed securities and treasury bonds (“quantitative easing” to inject liquidity into banks). Our central bank is now sitting on a portfolio of around $2 trillion in securities and has recently decided to keep that value constant by reinvesting principal pay-downs on mortgage and agency debt into long-term treasuries.

The above policies serve to keep a floor on mortgage rates and finance our government’s deficits at low interest (what used to be stealth monetization is now just monetization), while also providing cash to banks with the alleged hope that they will lend it out into the economy, where consumers and businesses will spend/invest the loaned money. Out there in the real world, no such lending has happened, as the banks are sitting on $1+ trillion in cash and the Fed is caught in a liquidity trap. This trap implies that any small increase in rates will have a disproportionate inverse effect on debt servicing costs and therefore spending and investment. As the notable Australian economist Steve Keen likes to point out, when the Fed’s objective is to create growth in the productive economy, the above policies simply amount to pushing on a string.

Private markets are currently saturated with debt and therefore very few people want to borrow money, and very few lenders want to make loans at affordable rates since debtors can barely pay back what they owe now. As mentioned before, interest rates have bottomed out and there is minimal economic activity to show for it. The velocity of money in the economy has collapsed, and the Fed’s policies merely transfer large sums of taxpayer money to major banks that use it to blow more speculative bubbles in stocks, bonds, commodities, and derivative bets on the price movements of those assets. A prominent blogger/author named Charles Hugh Smith would ask “cui bono” (who benefits?) from these policies, and the answer would not be 90%+ of our population (the top 1% hold 33.8% of all wealth and more than 50% of all stocks and bonds in America). Maybe a better question is who loses, and the answer to that would be a solid majority of American taxpayers and savers (since interest paid on deposits remains at next to nothing).

Another tactic used by the current administration is to directly intervene in the housing market to keep mortgage rates low and support prices, since they view housing as the primary cause of the current crisis. The U.S. Treasury (taxpayers) is currently guaranteeing more than 90% of all new mortgages issued in the last year through the government-sponsored enterprises of Fannie, Freddie and also the FHA. As we can see with the large downturn in recent housing data, this intervention has merely allowed us to kick the can a few feet down the road, and the can became significantly larger after we kicked it.

In effect, these interventionist policies keep prices artificially elevated for a little while and loan losses off of banks’ balance sheets, while homes become even less affordable for financially responsible people looking to buy. Even with record low mortgage rates, people are refusing to take on more debt to purchase an over-priced house unless there is a promise of a government handout lurking in the background, and the government simply cannot afford many more handouts. What much of the above interventionist policies amount to is a substitute of private debt held by politically influential groups for public debt held by the taxpayers and future generations, which ultimately creates even more disturbances in public credit markets and crowds out what’s left of private investment (more money has to go towards financing deficits).

The administration has also presented several “structural” fixes of the health care and financial industries for public consumption. These bills were thousands of pages long and filled with new regulations and tweaks to existing ones that really did nothing to address the underlying fundamental problems with these systems. The health care bill did little more than give the health insurance companies 30 million new customers through government mandate, and the “finreg” bill failed to break up the TBTF banks, audit the Fed or create transparency for risky derivative products. More importantly, these new top-down regulations have the inherent feature of creating unintended consequences in our complex society, despite the alleged best intentions of their creators, and can even make the targeted problem worse.

The financial reform bill created new restrictions on “angel investors” which will inadvertently stymie the creation/expansion of small businesses, while the behemoth investment banks will continue to exploit financial markets by hiring teams of lawyers to easily bypass the new regulations that affect them (as they are currently doing with the “Volcker Rule”) or by simply buying off the regulators. Meanwhile, as the administration pretends to combat fraudulent practices in the financial industry by creating a “Consumer Finance Protection Agency” (housed in the Fed), they actively aid financial institutions in committing accounting fraud by suspending federal rules that require them to mark their assets to market value (just another part of what many term “extend and pretend” policy).

Finally, another recent tactic of current governments has been the use of central bank intervention to suppress a politician’s worst nightmare in a deflationary economy, currency appreciation. The Swiss National Bank has admittedly bought up billions worth of Euros to prevent the Swiss Franc from appreciating too much during the ongoing European sovereign debt crisis of 2010, but they ended up taking significant losses on those transactions (and I’m confident that Germany didn’t mind the boost to exports provided by the Euro at 1.20 against the dollar). We can be rest assured that the central banks of the U.S., Japan and China have done the same type of intervention and will continue to do so when they feel it necessary.

Disregarding the inherent unsustainable nature of major economies racing to the bottom of the currency depreciation endgame, the marginal benefits of these interventions have severely contracted as their half-lives become shorter and shorter. Currency investors (who manage to trade $4T daily with 50x leverage) have realized that a central banker pushing a button somewhere to buy a few billion here and there will not change the fundamental economic realities faced by the global economy. Diminishing marginal returns, whether they are those of interventions or investments, are best viewed as a function of decelerating complexity. Razor thin margins in the global economy are no accident, but only the logical destination of our complex, infinite growth-based systems.

We should also consider the possibility that some or all of the above policies will miraculously be successful in creating sustained economic growth, price inflation, and wealth creation. In the case of such a rare event, the question still remains of when and how intervention can be stopped, and whether we will return to the same credit-based, consumption economy we had in the past. Will we merely restart the credit bubble and restore our modern lifestyles in the developed world? These questions in turn raise the issues of continued over-consumption of resources, environmental destruction and accelerating climate change, which are the most important long-term issues that humanity faces. After all, how long can an economy continue growing when billions of its supporting members around the world are dying of starvation, thirst and/or resource wars?

Our Disingenuous “Saviors”

Conservative politicians/pundits who adhere to the Tea Party mentality are, at best, disingenuous in their promises of returning to the status quo of economic growth and complexity with fiscal conservatism and small government. They suggest that many of our economic ills can be cured if we simply withdraw all government fiscal/monetary supports and drastically reduce public spending. Now it is true that spending should be drastically cut in certain areas, and intervention should be drawn down to a large extent, but the question then becomes what happens if we do that and not much else.

The break down of complexity in a system does not adhere to human concepts of fairness, order or social stability. If these politicians actually follow through with what they promise, a lot of wealth will be destroyed as asset prices, wages and business profit margins fall drastically. Societies grown accustomed to continual growth and high standards of living will have their expectations dashed and will experience the societal equivalent of post-traumatic stress disorder. There will be deterioration in social order, an increase in crime rates, and an exacerbation of people’s distrust/paranoia of all groups perceived as “different” or those claiming a right to the same piece of economic pie (the increasingly heated debates over illegal immigration is a great example of this dynamic).

Austerity measures are being pushed heavily in European countries and by many people in America concerned about public debt. Their concerns are entirely valid and something should be done to reduce deficits, but we must also be candid with the global population about what the term “austerity” really implies. It is actually another way of promoting reduced complexity in our modern society. Just as our debt-fueled private and public spending sprees have pulled forward energy/resources to maintain and evolve complexity, a global or nationwide savings plan would pull the resource rug out from under our extremely complex systems. This loss of complexity necessarily means much less economic activity and access to goods/services across distant locations.

For example, a $1 trillion reduction in government spending could easily translate into an equivalent or slightly higher reduction in GDP. As profit margins for businesses are squeezed from price deflation, more people will be laid off and that will further reduce demand and prices in a classical positive feedback. A deflationary spiral into depression is an extremely messy process, and when it stems from a financial crisis, fragile supply chains of goods/services will be disrupted since producers, distributors and purchasers will have limited or no access to letters of credit. This aspect of a debt deflation was clear during the first Great Depression, when farmers would throw perfectly good milk into ditches while other people were starving down the road.

The conservatives and libertarians also rave about the need for a complete extraction of government from economic and financial markets. While this extraction would certainly allow natural forces to take over and bring about a steady-state equilibrium sooner, it will be extremely ugly for some years. The method in which this is done is also important, because an immediate withdrawal of government supports from housing and financial markets would trigger major declines in economic growth and employment, as recent economic data should make evident. It would be more sensible to at least attempt a gradual withdrawal of support coupled with targeted aid to those most harmfully affected by the ensuing deflationary spiral. We should also remember that there’s a difference between funneling taxpayer money to banks via bailouts, quantitative easing, zero interest rate policy and various government backstops, and the government implementing fundamental structural reforms to the current setup of our financial institutions and credit markets. The latter must eventually be done to prevent the same exploitative systems we currently have from regaining their former levels of societal entrenchment.

Innovative Suggestions and Unanswered Questions

There are several other suggestions for “solving” our problematic encounter with peak complexity that attempt to restart sustained economic growth without introducing loads of new private/public debt or harsh austerity measures. For one, the government could abolish the Fed and literally print their own money (as Lincoln did with his greenbacks) and distribute it to households so they can pay down debts and spend/invest in the productive economy. This would allow banks to regain some value on their bad loans while also allowing consumers to get out of debt and regain some old spending/investing habits. We could also couple these monetary injections with structural reforms to the financial sector, limiting the ability of private banks to create unlimited credit and blow speculative bubbles. However, we can't analyze this situation in the vacuum of the American productive economy, since after all we are a part of a larger financial complex that stretches across the entire globe. I still find suggestions such as this one to be significantly more sensible than pure Neo-Keynesian or Libertarian policy prescriptions, so I will simply present a few questions that immediately come to mind (some of these are semi-rhetorical):

How will the domestic banks react as their debts are paid down with freshly printed money? Will they be concerned about inflation?

What about institutional investors currently holding cash and treasuries as their primary assets? Will this new stimulus spark a "risk on" mentality where assets/commodities are bid up and treasuries are dumped for cash to invest in risk plays? Can the Fed soak up all of these dumped treasuries and keep interest rates from rising and consuming a large part of government revenue (which would turn us into a much bigger Greece)?

What about our foreign creditors who will see others dumping treasuries while debts incurred to buy their cheap goods are being paid back with printed money? It is true that there will be much more debt overhang than money printed in the stimulus program, but hyperinflation is not so much an economic event as a sociopolitical one (internal or external loss of confidence in government institutions).

How much moral hazard will be created by such a significant bailout of debtors and creditors? Is current moral hazard already so high that marginal additions to it will be insignificant, or will it push us to a point where people, corporations and their politicians will refuse to ever abandon the current Ponzi system?

Another interesting policy idea is printed monetary stimulus and tax cuts for households combined with central bank monetization of treasury debt to offset lost tax revenues and keep interest rates stable. The federal income tax could be greatly reduced or even eliminated, and monetization could make up for the revenue shortfalls that result. This particular idea was actually mentioned by Ben Bernanke when speaking about Japan’s prolonged deflation and possible policy responses in a similar situation. Of course, with another idea designed to maintain the path of modern civilization comes more troubling questions (and all of the questions above still apply) :

As the dollar is devalued from printed stimulus and debt monetization, how will other major economies stuck in deflationary traps react to appreciating currencies and decreasing exports?

Follow up: Exactly how ugly can a trade war between major economies get?

How much stimulus will have to be applied before consumers and investors heal their scars, pull the cash out of mattresses and start spending/investing again?

Will the government pay back its expanded deficits with printed money, and if so what does this mean for the prospects of real or perceived inflation?

What will occur when “organic” growth has restarted and we attempt to unwind the drastic monetary policy interventions that have been undertaken? How do we restore our tax revenues in an acceptable way?

In light of these unanswered questions and others not asked yet, it appears that the more “innovative” suggestions offered to solve our predicament are still underestimating our complex, global society’s unpredictable reactions to various manipulations at the margin. Similar to the mainstream policies heavily criticized earlier, they certainly tend to ignore the tougher questions regarding what we will do to create a more sustainable society once we are successful in restarting economic growth for the time being. In all fairness, that issue is much broader in scope and more complicated to properly analyze, but it should always be lingering in the background. Taking into consideration all of the above criticisms of policies that attempt to maintain economic complexity, it is hard not to conclude that greatly reduced complexity is the only path to sustainability. There may not be anything “wrong” with our desire to maintain the complex systems we have evolved up to this point in time, except the fact that this desire may not be compatible with the laws of nature.

The Limits to Complexity

In 1972, several authors published a book entitled The Limits to Growth that explored the relationship between exponential population growth and finite resource supply/production. What they basically attempted to model was the extent to which a broad system (such as human civilization) could increase and maintain its complexity (best measured by population) in an environment with resource constraints that increase in an exponential or non-linear fashion. They viewed technological advances as a linear process that could not keep pace with the effects of population growth and resource depletion. In a subsection of the book, the authors made clear that their model was designed to illustrate what they termed “broad behavior modes” of human systems rather than make specific predictions regarding peak resources and population growth. They expanded on that concept using the following example:

If you throw a ball straight up into the air, you can predict with certainty what its general behavior will be. It will rise with decreasing velocity, then reverse direction and fall down with increasing velocity until it hits the ground. You know that it will not continue rising forever, nor begin to orbit the earth, nor loop three times before landing. It is this sort of elemental understanding of behavior modes that we are seeking with the present world model. If one wanted to predict exactly how high a thrown ball would rise or exactly where and when it would hit the ground, it would be necessary to make a detailed calculation based on precise information about the ball, the altitude, the wind, and the force of the initial throw. Similarly, if we wanted to predict the size of the earth's population in 1993 within a few percent, we would need a very much more complicated model than the one described here.”


With the above example, the authors are in essence describing a complex, dynamic system whose specific behaviors are unpredictable. The global economy certainly fits into this category, and of course it is entirely based on our current supply of energy/resources or the loosely estimated future supply we have borrowed against. This latter aspect of complexity represents the top of our global economic pyramid that is in the process of breaking down via “financial crises”, but more on that later. Our task here is not to determine exactly how the system will behave in the near future, but to take a bird’s eye view of general trends between multiple interacting variables. This perspective is something our current leaders, media pundits and mainstream academics fail to account for, and that’s why many of their “solutions” fall way short of achieving anything sustainable and are many times extremely destructive. We desperately need a fresh, new perspective on our current economic predicament before we can figure out the best ways to navigate through it.

Standing On the Brink of Release

Buzz Holling was instrumental in describing the adaptive cycles of complex ecological systems, and specifically he studied forest ecosystems. He identified 4 general stages of evolution in complex ecological systems (what he termed "fractal adaptive cycles"), and these could just as easily be applied to human systems that have been built on the foundation of those ecological systems (my descriptions will be greatly simplified – follow the referenced sources for more detail) :

1. Growth – The system finds an abundance of available resources and spaces which are exploited for material wealth, and this flow of energy/resources allows the development of many inter-dependencies, efficiencies and specialized functions. Diversity of agents within the system increases as does overall wealth.

2. Conservation – The system’s rapid growth decelerates as it becomes highly specialized and opportunities for novel exploitation strategies diminish. Increasing amounts of energy are directed towards conserving the existing system instead of growth, and “wealth” is extracted from the periphery to central parts of the system. The system’s complex inter-dependencies become more rigid and less resilient to disruptions that may propagate throughout the highly-connected networks of the system (Holling described the system at this stage as “an accident waiting to happen”).

3. Release – A relatively small triggering event exceeds the margins of error allowed in the system and pushes it into a chaotic liberation of energy and resources. The previous structures, relationships and complexities of the system are rapidly dismantled as central hubs deteriorate and networks are disconnected.

4. Reorganization – The fractured parts of the previous system re-structure themselves into more complicated relationships, but not necessarily in the way they were organized during the first growth phase. Typically, this phase leads to a restarting of the adaptive cycle in which many new opportunities for innovative development become available.

It is also important to note that complex ecosystems are typically composed of smaller systems and are also embedded in larger systems, creating a nested set of self-similar structures. Typically, the larger system can absorb much of the release from smaller systems contained within it, and act as a “memory bank” that allows rapid regeneration of the smaller system. If an individual American company goes bankrupt, its assets can typically be absorbed and immediately put back to use by other companies in that economic sector (assuming it does not have TBTF status). However, if the larger system is synchronized with the smaller system during the release and reorganization phases, then it could potentially lead to what Holling terms a “poverty trap”, in which low levels of wealth and connectivity are persistent.

It is pretty easy to see the progression of our global economy through the stages listed above. Since the industrial revolution, our fossil fuel inheritance has allowed local economies to become increasingly specialized, efficient and inter-connected with others to create even more efficiencies through trade and investment. On top of that, a smaller system of global finance has developed through equity and credit markets that traditionally facilitated productive investments in people, businesses and governments. Of course the last few decades have seen a rise in what can most accurately be called Ponzi finance, in which major creditors extract wealth from the global population by pushing non-productive debt on them and taking control of political institutions that could potentially stand in their way. To be fair to the debt pushers, we (in the developed world mostly) have gladly bought their drugs and have remained their loyal addicts to the bitter end.

The 2008 subprime housing crisis was the spark that ignited the release of our complex financial system, and unfortunately finance is such a large part of the global economy that there is not much of a larger economic system to absorb the fallout. It is also true that our oil-subsidized industrial economy is approaching its own stage of release that cannot be absorbed by an alternative energy economy, and as if things weren’t dire enough, it is arguably the case that our entire atmospheric system is synchronized as well due to the ongoing process of carbon emissions and climate change (the effects of which we are certainly experiencing now). The processes of growth and conservation in these systems of varied scales may have been temporally different, but it appears that the tipping points triggering release are converging within a few decades at most.

Instead of building resilience in the face of exponentially increasing complexity and decelerating growth, we have pushed forward full speed ahead and concentrated increasing amounts of resources/wealth in our corporate/governmental central hubs. We have become extremely vulnerable to any shocks that could potentially propagate throughout the system, as we recently witnessed when a few major banks held the entire global economy hostage. Now our debt-saturated governments are trying to save the current system by concentrating even more wealth in the center, but nature clearly has other plans. It is painfully clear that politicians, corporate executives, corporate media and all other central actors that have power to implement large-scale policies promoting resilience have chosen (intentionally or inadvertently – does it really matter?) their own material interests over that of the masses. We, as individuals and communities, must choose to implement our own policies of resilience, because we are ultimately a part of a much larger system than the economic, political or social systems that have been imposed on us.

We Can Survive With No Regrets

Some people find economic theories and abstract mathematic principles extremely dry and unfamiliar. I’m pretty interested in economics and finance, but I still find it painfully boring to watch Ben Bernanke testify about monetary policy in front of Congressional representatives, who probably find it even more boring than I do (which may explain their weak excuses for questions). But most people familiar with the modern world, especially those of us in fully “developed” countries, have intimate experience with complexity on a daily basis. We are constantly bombarded with facts and data regarding events and trends progressing around the world. We attend colleges with dozens of specialized majors and tracks of study within those majors. People constantly tell us that the world has become “smaller” due to telecommunications technology, which is true in a sense, but they fail to mention the world has also become exponentially more complex.

It is especially easy for us to identify the advantages of increased growth and complexity. These advantages are mostly materialistic in the sense that we have more financial “wealth” and higher standards of living. The disadvantages are sometimes harder to grasp since they are more ephemeral in nature. We are more isolated from nature, disconnected from local communities and uncertain about the future. Some of our most basic concepts and values, such as fairness, equality, cooperation, compassion and ethical behavior, have been watered down to the point of being topics for dinner tables or the occasional academic journal, but nothing else.

There are certainly material disadvantages to a complex, highly-dependent society as well, since many people have lost the knowledge/ability to grow food, build things, fix things and generally be self-sufficient. However, there has been at least one extremely important advantage to complexity in the development of advanced communications technology, and especially the internet which has connected billions of people across the globe. Insightful thinkers can use the internet to communicate their ideas to people in a distant location such as me, and I can then use their ideas to write a short essay such as this one, and send it to several others. We can use the communications networks to take back some level of knowledge, cooperation and resilience that we may have lost.

There are five general areas of resilience that every individual and family should understand and take incremental steps towards. These include food security, water security, energy security, health security, and financial security. There are many tremendous writers out there that have written and spoken volumes on these issues and have generously shared their knowledge with anyone willing to read or listen.

The quicker we individually quit acting like deer caught in the headlights, and take actions towards resilience, the better off we will be as a collective species on a planetary system that has generously supported us, and continues to do so. The upcoming years will truly be a unique, eventful chapter in the history of human evolution. Perhaps in whatever records of history that may survive this rapid transformation, we will be known as the “peak generations” who sacrificed their extraordinary wealth, lifestyles, and comforts for a more simple form of social organization, where we re-organized to create a sustainable, just society. More likely, we will end up being the “peak generations” that fought desperately to defy reality and ended up in a heap of our own rubble. Either way, we should not focus on what society thinks about us now or how we will be remembered in the future. We should only be focused on doing what needs to be done, and then we should do it with no regrets.

Peak Oil is History

The marketing blurb on the back cover of the first edition of my first book, Reinventing Collapse, described me as "a leading Peak Oil theorist." When I first saw it, my jaw dropped -- and remained hanging. You see, if you run through a list of bona fide leading Peak Oil theorists -- your Hubberts, your Campbells, Laherrères, Heinbergs, Simmonses and a few others worth mentioning, you will not find a single Orlov among them. In vain would you search the annals and conference proceedings of the Association for the Study of Peak Oil for any trace of your humble author. But now that this howler is in print and circulated in so many copies, I suppose I have no choice but to try to live up to the expectation it set.

My disqualifications aside, now does seem to be an auspicious moment to hold forth with a new piece of Peak Oil theory, because this is the year when, for the first time, just about everyone is ready to admit that Peak Oil is real, in essence, though some are not quite ready to call it by that name. Just five years ago everyone from government officials to oil company executives treated Peak Oil theory as the work of a lunatic fringe, but now that conventional world oil production peaked in 2005, and all liquids world production peaked in 2008, everyone is ready to concede that there are serious problems with growing the global oil supply. And although some people still feel skittish about using the term Peak Oil (and a few experts still insist that the peak must be referred to as "an undulating plateau," which, if anything, is a graceful turn of phrase) the differences of opinion now largely stem from a refusal to accept the terminology of Peak Oil rather than the substance of peaking global oil production. This is, of course, quite understandable: it is awkward to suddenly jump from shouting "Peak Oil is bunk!" to shouting "Peak Oil is history!" in a single bound. Such acrobatics are only safe if you happen to be a politician or an economist.

Now that the matter has been largely settled, I feel that the time is ripe for me to weigh in on the subject and declare, unequivocally, that Peak Oil is indeed bunk. Not the part about global oil production reaching a peak sometime right around now then declining inexorably: that part seems true enough. Nor the part about oil production in any given province becoming constrained by geology and technology once the peak is reached: that part, under properly designed experimental conditions, seems predictive as well. In fact, the depletion model has been confirmed beautifully by the example of the continental United States minus Alaska since 1970. But the idea that this same depletion model can be applied to the planet as a whole, is, I feel, something that must be rejected as utterly and completely bogus. To see what I mean, look at a typical Peak Oil chart (Fig. 1) that shows global oil production climbing up to a peak and then declining.

Image

Observe that the upward slope has a lot of interesting structure to it. There are world wars, depressions, imperial collapses, oil embargoes, discoveries of giant oil fields, not to mention the ugly boom and bust cycles that are the bane of capitalist economies (whereas socialist ones have sometimes been able to grow, stagnate and eventually collapse far more gracefully). It is a rugged slope, with cliffs and crevasses, craggy outcrops and steep inclines. Now look at the downward slope: is it not shockingly smooth? Its geologic origin must be completely different from that of the upward slope. It appears to be made up of a single giant moraine, piled to the angle of repose near the top, with some spreading at the base, no doubt due to erosion, with a gradual transition into what appears to be a gently sloping alluvial plain no doubt composed of silt from the runoff, which is then followed by a vast perfectly flat area, which might have been the bottom of an ancient sea. If climbing up to the peak must have required mountaineering techniques, the downward slope looks like it could be negotiated in bathroom slippers. One could do cartwheels all the way down, and be sure of not hitting anything sharp before gently rolling to a stop sometime around 2100. Mathematically, the upward slope would have to be characterized by some high-order polynomial, whereas the downward slope is just e-t with a little bit of statistical noise. This, you must agree, is extremely suspicious: a natural phenomenon of great complexity that, just when it is forced to stop growing, turns around and becomes as simple as a pile of dirt. Where else have we observed this sort of spontaneous and sudden simplification of a complex, dynamic process? Physical death is sometimes preceded by slow decay, but sooner or later most living things go from living to dead in an abrupt transition. They don't shrivel continuously for decades on end, eventually becoming too small to be observable. And so I like to call this generic and widely accepted Peak Oil case the Rosy Scenario. It's the one in which industrial civilization, instead of keeling over promptly, joins an imaginary retirement community and spends its golden years tethered to a phantom oxygen tank and a phantom colostomy bag.

The really odd thing is that the Rosy Scenario can be quite accurate, under ideal circumstances, when applied to individual countries and oil-producing regions. For instance, suppose one of the world's largest oil producers, which started out with more oil than Saudi Arabia, reaches Peak Oil in, say, 1970, but then promptly goes off the gold standard, foists its paper currency on the rest of the world by backing it up with the threat of force including the possibility of a nuclear first strike, eventually comes to import over 60% of its petroleum, much of it on credit, and, a few decades later, goes bankrupt. Then, over the intervening decades, its domestic oil production would indeed exhibit this wonderfully gentle geologically and technologically constrained curve -- up to the point of national bankruptcy.

Image
Fig. 2

Past the point of national bankruptcy circumstances are bound to become decidedly non-ideal, but the implications of this remain unclear. Will that hapless country still be able continue borrowing money internationally in order to import enough oil to keep its economy functioning, and, if so, under what terms, and for how much longer? It would be nice to know how this story ends ahead of time, but unfortunately all we can do is wait and see.

But we do have another example (Fig. 3), which may offer some insights into what we mean when we say that circumstances will be “non-ideal.” The country that is currently the world's largest oil producer reached Peak Oil around 1987. Its sclerotic, geriatric, ideologically hidebound, systemically corrupt leadership was unable to grasp the importance of this fact, and just three years later the country was bankrupt and, shortly thereafter, it dissolved politically. In this case, plummeting oil production became the country's leading economic indicator: it plummeted, then the GDP plummeted, then coal and natural gas production plummeted, and a decade later the economy was down 40%. Behind these numbers was a precipitous drop in life expectancy and a pervasive atmosphere of despair in which many lives were either lost or ruined.

But as long as no messy internal or external political or economic factors interfere with the natural depletion curve, the après-Peak predictions of Peak Oil theory do seem to hold. (When I say “ideal circumstances,” I suppose that I must mean circumstances that are ideal from the point of view of sentient though irrational hydrocarbon molecules, whose desire is to be pumped out of the ground and burned up as quickly and efficiently as possible, because it is unclear who else ultimately benefits, but let's not quibble.) Since the problem of not having enough oil to go around is known to cause all sorts of nasty political and economic problems, and since this is exactly the problem we should expect to encounter soon after the world reaches Peak Oil, the base assumption on which the predictions of Peak Oil theory for global oil production rest is not realistic. The specialists who are in a position to predict Peak Oil are not able to gauge its economic and political effects, and so all they can do is give us the Rosy Scenario as an ultimate upper bound. However, this caveat is not spelled out as clearly as it should be. The result is that we might as well be working with a theory which predicts that, once global Peak Oil is reached, delicious chocolate petits fours will spontaneously bake themselves into existence and fly into our mouths on dainty gossamer wings of marzipan.

The Peak Oil theory-based explanation is that while the upward slope is economically constrained, the downward slope is only constrained by the geology of depleting oil reservoirs and by oil extraction technology, which is subject to thermodynamic limits and cannot improve forever without encountering diminishing, then negative, returns. While the oil supply is growing, oil demand fluctuates, resulting in numerous ups and downs in production superimposed on the overall upward trend as production tries to match demand. But on the downward side, demand permanently exceeds supply, and so every barrel of oil that can be produced at each instant will be produced.

When extrapolating the aftermath of local oil production declines to global Peak Oil, the unstated assumption is that the global economy will continue to function with uncanny smoothness at the level of demand that can be met, while unmet demand will be cleanly washed off into the gutter by a strong, steady stream of economic and political nonsense. This will all sort itself out spontaneously with rational market participants responding to price signals and deciding at each instant whether they should:

A. continue consuming oil in the manner to which they have become accustomed, or

B. quietly wander off and die without calling attention to themselves or making a fuss.

Where else have we seen such flawless organization, in situations where a key commodity -- like, say, food, or drinking water -- becomes critically scarce? Anywhere? Anywhere at all?

And I suppose a further unstated assumption is that a shrinking economy (what with all this unmet demand and resulting attrition among market participants) can function much as a growing one does, without suffering a financial collapse. Special financial instruments called credit-default swaps can be used as a hedge against increased counterparty risk from your counterparties dying in droves from self-inflicted wounds, although after a while these instruments would become a bit too expensive. But I don't suppose that much of anything can be done about the economic growth projections baked into every single financial plan at every level. Once these turn out to be unfounded, then all the debt pyramids will come tumbling down. And since a fiat currency (such as the US Dollar) is composed of debt -- credit advanced based on a promise of future growth -- it is unclear how and with what the remaining oil will continue to be purchased. The end of growth is an imponderable; start talking about it, and everyone suddenly decides that it's lunchtime and starts ordering drinks. At least the French have a proper word for it: décroissance (literally, “de-growth”); here in the anglophone world all we can do is gibber and mumble about “double-dips.” Perhaps Geithner and Bernanke can come up with a dance number to illustrate.

Let us look at it another way. As I mentioned, Peak Oil theory has been quite good at predicting the depletion profile of certain stable and prosperous countries and provinces. But these predictions become meaningless when extrapolated to the world as a whole, for one very obvious reason: the world cannot import oil. Let me say it again, this time in title-case, bolded and centered, to emphasize the significance of this statement:

Planet Earth Can't Import Oil

When faced with insufficient domestic oil production, an industrialized country has but two choices:

1. Import oil

2. Collapse

But when faced with insufficient global oil production, an industrialized planet has just one choice: Choice Number 2.

Some might argue that there is a third choice: start using less oil right away. However, in practice this turns out to be equivalent to Choice Number 2. Using less oil involves making some radical, often technologically challenging, politically unpopular, and therefore expensive and time-consuming changes. These may be as technologically advanced (and unrealistic) as replacing the current motor vehicle fleet with electric battery-powered vehicles and a large number of nuclear power plants to recharge their batteries, or as simple (and quite realistic) as moving to a place that is within walking or bicycling distance from your work, growing most of your own food in a kitchen garden and a chicken coop, and so on. But whatever these steps are, they all require a certain amount of preparation and expense, and a time of crisis (such as when oil supplies suddenly run short) is a notoriously difficult time to launch into long-range planning activities. By the time the crisis arrives, either a country has already prepared as much as it could or wanted to (thereby delaying the onset of collapse) or it has not, bringing the crisis on sooner, and making it more severe. The oft-cited Hirsch Report states that it would take twenty years to prepare for Peak Oil in order to avoid a severe and prolonged shortage of transportation fuels, and so, given that the peak was back in 2005, we now have minus five years left to lollygag before we have to start preparing. According to Hirsch et al., we have failed to prepare already.

Some might also wonder why a shortage of oil should automatically trigger a collapse. It turns out that, in an industrialized economy, a drop in oil consumption precipitates a proportional drop in overall economic activity. Oil is the feedstock used to make the vast majority of transportation fuels -- which are used to move products and deliver services throughout the economy. In the US in particular, there is a very strong correlation between GDP and motor vehicle miles traveled. Thus, the US economy can be said to run on oil, in a rather direct and immediate way: less oil implies a smaller economy. At what point does the economy shrink so much that it can no longer meet its own maintenance requirements? In order to continue functioning, all sorts of infrastructure, plant and equipment must be maintained and replaced in a timely manner, or it stops functioning. Once that point is reached, economic activity becomes constrained not just by the availability of transportation fuels, but also by the availability of serviceable equipment. At some point the economy shrinks so much as to invalidate the financial assumptions on which it is based, making it impossible to continue importing oil on credit. Once that point is reached, the amount of transportation fuels available is no longer limited just by the availability of oil, but also constrained by the inability to finance oil imports.

The initial shortage of transportation fuels need not be large in order to trigger this entire cascade of events, because even a small shortage triggers a number of economically destructive feedback loops. A lot of fuel is wasted by idling in line at the few gas stations that remain open. More fuel is wasted by topping off -- keeping the tank as full as possible, not knowing when and where you will be able to fill it again. Even more fuel disappears from the market because people are hoarding it in jerrycans and improvised containers. As the shortages drag on and spread, fuel is hoarded, and a black market for it develops: fuel diverted from official delivery channels and siphoned from gas tanks becomes available on the black market at inflated prices. And so the effect of even a minor initial shortage can easily snowball into an economic disruption sufficient to push the economy over physical and financial thresholds and toward collapse.

If at this point you are starting to feel despondent, then -- I am sorry to have to say this, but you must be a lightweight, because there is more -- lots more to consider. Peak Oil's Rosy Scenario may look pretty, but even a rose has its thorns. And there are a number of other issues which need to be considered and taken into account within a single, integrated view.

First, the rosy post-Peak Oil global production profile is based on reserve numbers which have been overstated. Much of the remaining oil is in the Middle East, in OPEC countries, and these countries overstated their reserves by various large amounts during OPEC's “quota wars” back in the 1980s. While other OPEC members sheepishly cooked up bogus numbers that looked vaguely real, Saddam Hussein, who was always a bit of a showboat, rounded up Iraq's reserve numbers up to a nice round number: 100 billion barrels. And so OPEC reserves turn out to have been inflated by some large amount -- about a third at a minimum. Nor is OPEC unique in overstating their reserve numbers. Energy companies in the US play much the same game in order to please Wall Street. Set your bathroom slippers aside; to negotiate Peak Oil's downward slope you will need good mountaineering equipment.

Second, there is a phenomenon called Export Land Effect: oil-exporting countries, when their production starts to falter, have a strong tendency to cut exports before cutting into domestic consumption. To be sure, there are some countries that have surrendered their resource sovereignty to international energy companies and have lost control over their export policies. There are also some despotic regimes that starve their domestic consumers but to continue to earn the export revenue needed to prop up the regime. But most countries will only export their surplus production. This means that it will become impossible to buy oil internationally long before all the wells run dry, leaving oil importing countries out in the cold. Thus, if you live in an oil-importing country and thought you could negotiate the downward slope of Peak Oil in your hiking boots, put them aside. You will need a parachute.

Third, although total quantities of oil produced throughout the world were increasing up until 2005, the amounts of oil-based products (gasoline, diesel, etc.) delivered to their points of use peaked years earlier, in terms of usable energy derived. This was because more and more energy has been required to get a barrel of oil out of the ground and to refine it. Supplies of available crude oil have tended to become harder to extract, heavier, and more sulfur laden, plus the demand for more gasoline (as opposed to distillates or bunker fuels) with less lead for boosting octane add up to more energy being wasted. Energy Returned on Energy Invested (EROEI) went from 100:1 at the dawn of the oil age, when some strong-backed lads could dig you an oil well using picks and shovels, to an average of 10:1, now that oil production requires deepwater platforms (that sometimes blow up and poison entire ecosystems), horizontal drilling and fracturing technology, secondary and tertiary recovery using water and nitrogen injection, oil/water separation plants, and all sorts of other technical complexities which consume more and more of the energy they produce. As EROEI decreases from 10:1 toward 1:1, the oil industry comes to resemble an obese but famished wet-nurse ravenously sucking her own breast at the crib of a starving infant. At some point it will no longer be economically possible to deliver diesel or gasoline to a gas station. When that point comes is not certain, but there are some indications that 3:1 is the minimum EROEI that the oil industry requires in order to sustain itself. The effect of decreasing EROEI is to make the gentle slope of the Rosy Scenario much steeper. The slope no longer looks like a mound of pebbles -- more like lava flowing into the sea and solidifying in a cloud of steam. There may be plenty of energy left, but much of it is going to go by the wayside, and you might not be able to get close enough to it to roast your marshmallows.

Fourth, we must consider the fact that our modern global oil industry is highly integrated. If you need a certain specialty part for your drilling operation, chances are it can be sourced from just one or two global companies. Chances are this company has some very important, highly technical operations in a country that just happens to be an oil importer. The significance of this becomes clear when one considers what happens to that company's operations once Export Land Effect becomes felt. Suppose you are a national oil company in an oil-rich nation that still has enough oil left for domestic consumption, although it was recently forced to fire all of its international customers. Your oil fields are huge but mature, and you can only keep them in production by continuously drilling new horizontal wells just above the ever-rising water cut and maintaining well pressure by injecting seawater underneath. If you stop or even pause this activity, then your oil, at the wellhead, will quickly change in composition from slightly watery oil to slightly oily water, which you might as well just pump back underground. And now it turns out that the equipment you need to keep drilling horizontal wells comes from one of these unlucky countries that used to import your oil but now cannot, and the technicians who used to build your equipment have given up trying to find enough black-market gasoline to drive to work and are busy digging up their suburban backyards to grow potatoes. A short while later your drilling operations run out of spare parts, your oil production crashes, and most of your remaining reserves are left underground, contributing to an increasingly important reserve category: never-to-be-produced reserves.

When these four factors are considered together, it becomes difficult to imagine that global oil production could gently waft down from lofty heights in a graceful smooth and continuous curve spanning decades. Rather, the picture that presents itself is one of stepwise declines happening in more and more places, and eventually encompassing the entire planet. Whoever you are, and wherever you are, you are likely to experience this as a three-stage process:

Stage 1: You have your current level access to transportation fuels and services

Stage 2: You have severely limited access to transportation fuels and services

Stage 3: You have no access to transportation fuels and severely restricted transportation options

How long Stage 2 will last will vary from one place to another. Some places may go directly to Stage 3: gasoline tankers stop coming to your town, all the local gas stations close, and that is that. In other places, a thriving black market may give you some access to gasoline for a few years longer, at prices that will allow some uses, such as running an electrical generator at an emergency center. But your ability to successfully cope with Stage 2, and to survive Stage 3, will be determined largely by the changes and preparations you are able to make during Stage 1.

It should be expected that the vast majority of people will have done nothing to prepare, remaining quite unaware of the fact that this is something they should have been doing. Quite a few people can be expected to take a few small steps in a sensible direction, such as installing a wood stove, or insulating their home, or in a seemingly sensible but ultimately unhelpful direction, such as wasting their money on a new hybrid car or wasting their energies on trying to form a new political party or to lobby one of the existing ones. Some will buy a homestead, equip it for life off the grid, start growing all their own food (perhaps transporting their perishable surplus to a nearby farmer's market by cargo bicycle or by boat), and home-school their children, putting an emphasis on the classics and on agriculture, animal husbandry and other perennially useful knowledge. Some will flee to a place where transportation fuels are scarce already, and where a moped is considered a labor-saving device -- for your donkey or camel.

Unfortunately, it is hard to foresee which changes and adaptations will succeed and which will fail, because so much depends on the circumstances, which are sure to be unpredictable and vary from place to place, and on the person or persons involved: the uncertainty is just too great. But there is one thing of which we can be quite sure: that Peak Oil's Rosy Scenario, which projects a long and gradual global oil production decline, is bunk. Knowing this fact should impart a sense of urgency. Whether we use that sense of urgency foolishly or wisely is up to us, and our success may be a matter of luck, but having a sense of urgency is not at all bad. If we wish to prepare, we most likely have a few months, we may have a few years, but we certainly do not have a few decades. Let those who would have you believe otherwise first consider the issues I have raised in this article.

Poverty of Imagination in an Age of Diminishing Resources

Slide show from the talk I just gave at Community Action Partnerships Annual Convention.
