While most governments' eyes are on the banking crisis, a much bigger issue - the environmental crisis - is passing them by, says Andrew Simms. In the Green Room this week, he argues that failure to organise a bailout for ecological debt will have dire consequences for humanity.

"Nature Doesn't Do Bailouts!" said the banner strung across Bishopsgate in the City of London.

Civilisation's biggest problem was outlined in five words over the entrance to the small, parallel reality of the peaceful climate camp. Their tents bloomed on the morning of 1 April faster than daisies in spring, and faster than the police could stop them.

Here we are, faced with the loss of an environment conducive to human civilisation, and we find governments prostrate before barely repentant banks, with their backs to a far worse ecological crisis

Across the city, where the world's most powerful people met simultaneously at the G20 summit, the same problem was almost completely ignored, meriting only a single, afterthought mention in a long communique.

World leaders dropped everything to tackle the financial debt crisis that spilled from collapsing banks.

Gripped by a panic so complete, there was no policy dogma too deeply engrained to be dug out and instantly discarded. We went from triumphant, finance-driven free market capitalism, to bank nationalisation and moving the decimal point on industry bailouts quicker than you can say sub-prime mortgage.

But the ecological debt crisis, which threatens much more than pension funds and car manufacturers, is left to languish.

It is like having a Commission on Household Renovation agonise over which expensive designer wallpaper to use for papering over plaster cracks whilst ignoring the fact that the walls themselves are collapsing on subsiding foundations.

Beyond our means

Each year, humanity's ecological overdraft gets larger, and the day that the world as a whole goes into ecological debt - consuming more resources and producing more waste than the biosphere can provide and absorb - moves ever earlier in the year.

The same picture emerges for individual countries like the UK - which now starts living beyond its own environmental means in mid-April.

Solar panels
Bad market design, feeble carbon reduction targets and the recession have all conspired to drive down the cost of carbon emission permits

Because the global economy is still overwhelmingly fossil-fuel dependent, the accumulation of greenhouse gases and the prognosis for global warming remain our best indicators of "overshoot".

World famous French free-climber Alain Robert, known as Spiderman, climbed the Lloyds of London building for the OneHundredMonths.org campaign as the G20 met, to demonstrate how time is slipping away.

Using thresholds for risk identified by the Intergovernmental Panel on Climate Change (IPCC), on current trends, in only 92 months - less than eight years - we will move into a new, more perilous phase of warming.

It will then no longer be "likely" that we can prevent some aspects of runaway climate change. We will begin to lose the climatic conditions which, as Nasa scientist James Hansen points out, were those under which civilisation developed.

Small dividend

As "nature doesn't do bailouts", how have our politicians fared who ripped open the nation's wallet to save the banks?

Not good.

According to the International Monetary Fund (IMF), the UK spent a staggering 20% of its GDP in support of the financial sector.

Yet the amount of money that was new and additional, announced in the "green stimulus" package of the Treasury's Pre-Budget Report, added-up to a vanishingly small 0.0083% of GDP.

Globally, the green shade of economic stimulus measures has varied enormously. For example, the shares of spending considered in research by the bank HSBC to be environmental were:

  • the US - 12%
  • Germany - 13%
  • South Korea - 80%

The international average was around 15%. HSBC found the UK planned to invest less than 7% of its stimulus package (different from the bank bailout) in green measures.

Comparing the IMF and HSBC figures actually reveals an inverse relationship - proportionately, those who spent more on support for finance had weaker green spending.

So here we are, faced with the loss of an environment conducive to human civilisation, and we find governments prostrate before barely repentant banks, with their backs to a far worse ecological crisis.

Extreme markets

On top of low and inconsistent funding for renewable energy, the shift to a low carbon economy is being further frustrated by another market failure in the trade for carbon seen, for example, in the EU's Emissions Trading Scheme.

Climbing building
"Spiderman" scaled the Lloyds Building in support of the climate campaign

Bad market design, feeble carbon reduction targets and the recession have all conspired to drive down the cost of carbon emission permits, wrecking economic incentives to grow renewable energy.

Worse still, the difficulty of accounting to ensure that permits represent real emissions has led both energy companies and environmentalists to warn of an emerging "sub-prime carbon market".

Relying on market mechanisms is attractive to governments because it means they have less to do themselves. But they will fail if carbon markets are just hot air.

There seems to be a hard-wired link between memory failure and market failure.

As the historian E J Hobsbawm observed in The Age of Extremes: "Those of us who lived through the years of the Great Slump still find it almost impossible to understand how the orthodoxies of the pure free market, then so obviously discredited, once again came to preside over a global period of depression in the late 1980s and 1990s".

Perhaps the greatest failure is one of imagination.

Some people alive today lived through those past recessions and depressions. They know they can be nasty and need averting.

But the last time the Earth's climate really flipped was at the end of the last Ice Age, more than 10,000 years ago. No one can remember what that felt like.

Lessons of history

Looking forward, the IPCC's worst case scenario warns of a maximum 6C rise over the next century.

Looking back, however, indicates that an unstable climate system holds worse horrors.

Work by the scientist Richard Alley on abrupt climate change indicates the planet has previously experienced a 10C temperature shift in only a decade, and possibly "as quickly as in a single year".

And, around the turn of the last Ice Age, there were "local warmings as large as 16C".

Imagine that every day of your life you have taken a walk in the woods and the worse thing to happen was an acorn or twig falling on your head.

Then, one day, you stroll out, look up and there is a threat approaching so large, unexpected and outside your experience that can't quite believe it, like a massive gothic cathedral falling from the sky.

In tackling climate change we need urgently to recalibrate our responses, just as governments had to when they rescued the reckless finance sector.

Then officials had to ask themselves "is what we are doing right, and is it enough?"

They must ask themselves the same questions on the ecological debt crisis and climate change.

The difference is, that if they fail this time, not even a long-term business cycle will come to our rescue. If the climate shifts to a hotter state not convivial to human society, it could be tens of thousands of years, or never, before it shifts back.

Remember; nature doesn't do bailouts.

Comments:

I think this is a good example of market failure as resources such as professionals are immediately allocated to resolve the current economic crisis when there is a bigger impending global crisis since many years back: global warming.

I feel that the UK government is undermining the effects of this economic problem as they only intend to invest less than 7% of its stimulus package in green measures compared to the amount it is investing in support of the financial sector, which is about 20% of its GDP. The international average of spending on environmental issues is on the average, 15%.

Furthermore, the government is relying too much on the market mechanism, as the adjustment of the market is natural due to demand and supply factors and requires little of their intervention. However, environmental problems, if left to the market, will worsen as producers will ignore any quota and continue to harm the environment to increase their revenues, that the marginal social cost is higher than their marginal private cost, which causes the environment to lose out more.

Hence i feel that the governments should do more to tackle the environmental issues, to resolve the market failure by allocating enough resources and attention to the causes of global warming.

The problem of overtaxing and undertaxing

Taxes are compulsory payments made to the government by firms and individuals, and they are implemented to reduce production and consumption levels to the socially efficient level, where MSB=MSC.

Governments should impose a tax that is equal to the marginal external cost (MEC). However, it is difficult to measure the exact MEC and therefore, it is hard for the government to impose the correct amount of tax. This will lead to the problem of overtaxing or undertaxing. Both overtaxing and undertaxing leads to market failure as resources are still not allocated efficiently.

Undertaxing brings the economy closer to the optimal level. However, overtaxing discourages producers from producing and this leads to quantity supplied being lower than expected. This may even lead to multinational companies withdrawing their investments and investing in other countries with lower taxes. This is an undesirable outcome as a new inefficiency is created.

Thus, overtaxing is more problematic.

Mini mindmap!


this is a mindmap on the examples of externalities

examples of externalities

What are Externalities?

An externality is a cost or benefit that affects someone not directly involved in the production or consumption of a good, and which occurs without compensation. Externalities are in effect a type of market failure. When an externality exists, either too much or too little is either produced or consumed than the market price dictates.

There are Positive and Negative externalities, external cost or benefit, and as a subsection of each there are producer and consumer externalities. Here is an example of each:

Positive Producer Externality/ external benefit in production
Education creates a positive externality because more educated people are less likely to engage in violent crime, which makes everyone in the community, even people who are not well educated, better off.

Positive Consumer Externality/ external benefit in consumption
An individual planting an attractive garden in front of his house may provide benefits to others living in the area, and even financial benefits in the form of increased property values for all property owners.

Negative Producer Externality/ external cost in production
The harvesting by one fishing company in the ocean depletes the stock of available fish for the other companies and overfishing may be the result. This is an example of a common property resource, sometimes referred to as the Tragedy of the commons.

Negative Consumer Externality/ external cost in consumption
An example would be when someone throws away the wrapping to a present. The wrapping is then eaten by a farm animal and the animal dies

Factor leading to market failure: Inefficiency

Market failure occurs when the price mechanism has failed to achieve efficiency in resource allocation and equity in income and wealth distribution.

Economic efficiency is only achieved when it is not possible to change the existing allocation of resources in a way that makes one person better off without making someone else worse off.
This can only be achieved when productive efficiency and allocative efficiency is met.

Looking into allocative efficiency, we must ensure that every sector in the market produces an output whereby MSB = MSC. Only at this output level, will then the sum of consumer and producer be maximized, leading to yet another maximization of soceity's welfare.

Under perfect competition and no externalities, there would be no divergence between private and social costs and benefits---------> MPB=MSB, MPC=MSC.
The result is that the market equilibrium output coincides with the socially optimum output and hence the resources in the market would be used efficiently.

However, if MSC was to exceed MSB, it would lead to a welfare loss and hence a situation of allocative inefficiency where the soceity's welfare is not maximized.

In conclusion, it is vital for the government to ensure that the society's welfare is maximized in order for the market to progress. He should focus on the inefficieny in resource allocation if there is any to correct market failure.

Is overtaxing or undertaxing more problematic?

Taxes are compulsory payments made to the government by individuals and firms. Both overtaxing and undertaxing lead to the inefficient allocation of resources, resulting in market failure.

While undertaxing brings the economy closer to the optimal level, overtaxing may discourage producers from producing and output produced will be lower than the optimal level. In some circumstances, foreign producers may even decide to locate elsewhere to avoid paying such high taxes. In the latter, society's welfare is even lower than before tax. Thus, overtaxing is definitely more problematic as compared to undertaxing.

On the other hand, most cities are building new slums faster than they can save from destruction and renew their old slums. Urban decay and blight are diffusing into new areas faster than all the huge sums of money spent on urban redevelopment and public housing can relieve existing slums. This would definitely happen as long as our urban tax system subsidises slums by undertaxing and deter improvements by overtaxing.

Moreover, overtaxing may add on to the burdens of the lives of the people and firms. Thus, this may make the lives of the people more difficult and firms may close down due to the high taxation.

Thus, it is no doubt that overtaxing is more problematic than undertaxing.

Overtaxing is more problematic.

Overtaxing is more problematic.

Taxes are complulsory payments to be made to the government by firms and individuals.

In the case of external cost in production, taxing is one of the solutions to reduce production & consumptions levels. This is to achieve social efficiency, where MSB(marginal social benefit)=MSC(marginal social cost).

As it is difficult to measure the exact external cost in production, overtaxing or undertaxing may occur. Undertaxing will, more probably, allow social efficiency to be attained. The optimal level will be reached. However, if overtaxing occurs, producers will be discouraged instead. Either they will produce less, or more firms will back out from the market.

Also, foreign producers may choose to re-allocate(in other countries) if they feel the taxes imposed are too high. This leads to the welfare of the society to be lower than it was before the tax was imposed.

Therefore, overtaxing is definitely more problematic than undertaxing.

How to Overcome Market Failure?

Market failure occurs when the price mechanism is unable to allocate resources efficiently and equitably. This is where the government needs to intervene and come up with solutions to enable the allocation of scarce resources.

Now then, how can market failure be overcome?

(With reference to this Video: http://www.youtube.com/watch?v=Unh9uJggjRg)

In the event of external cost of production, the government should intervene and carry out various plans, such as implementing taxes or providing subsidies. This is to correct externalities to obtain social efficiency, where Marginal Social Benefits=Marginal Social Costs (MSB=MSC).

Taxes are payments that producers and consumers are required to make to the government.

In the event of external benefit in production and/or external benefit in consumption, subsidies should be granted by the government to producers. This is in a bid to increase supply(in the case of external benefit in production) and to increase demand(in the case of external benefit in consumption).

Case study: Primary healthcare in S'pore

Some background information
  • A recent study by Wong CY et al revealed that, which quantified the perception that as compared to last decade, GPs are operating under more trying conditions.
  • Costs have increased: rentals by 31.4%, drugs by 41.7%, utilities/ laboratory by 58.8%. However consultation fees have only increased by 25.4%, and the GP's income has largely stagnated over the past 10 years (mean monthly income 2006: $10,524, 2007: $10,271).

How will this trend lead to market failure in Singapore?
  • Figure 1 above shows how low quality standards and especially low pricing, led to a lower combined supply curve.
  • The actual demand for good GP care by patients has also declined.
  • An uninformed patient faces a combined supply of good (well trained) and less well trained GPs, and knows he has a chance of drawing an "adverse selection", because he may have little knowledge on how to differentiate between the two - there is asymmetry of information.
  • He thus lowers his demand curve, and is not willing to pay a premium, even if he sees a doctor with "GDFM" or "MMed" tagged to his name.
  • Lower price (consult fees) drives out better quality.
  • Less doctors are willing to supply service at this price. Junior doctors are not keen to take up further FM training, and trained ones are not keen to join the market.
  • Consumers will then face the GP market with even worse adverse selection.
  • As the demand curve adjusts lower and lower (the red line in Figure 1 above), and the combined supply curve shifts further from that of good GP care, there will come a point in time when supply of bad quality exceeds demand, and only the bad ones are left in market. This is market failure of healthcare.
Solution?
  • The Family Physician Register introduces an Appraisal Mechanism to objectively resolve the asymmetry of information and differentiate the well trained GPs from the rest.
  • Doctors who chose to take up the 2-3 year of FM training would be able to signal to the patients that they were serious about upgrading of skills in order to offer better treatment.
  • The need to invoke the support of the so-called 4Ps - people, press, policy makers and profession is recognized. The public and our patients need to be convinced that they are well trained and capable to take on mainstream Family Medicine, chronic disease management, right-siting, integrated care.
In conclusion, when more consumers are aware of the value and willing to pay the due worth of good care, then the demand-supply curves will meet at a different point, preventing market failure.
