No market is perfect and when the market mechanism fails to deliver an efficient allocation of resources, we say the market fails and hence there is justification for some government intervention. From a monopolist dominating an industry to a manufacturing firm pumping out pollution, there are countless examples of market failure.
The Guardian is creating a guide to climate change, covering areas from politics to economics. The problem of climate change has been well documented and this blog considers a particular issue – the case for climate change or the environment as a market failure. In many cases just one market failure can be identified, for example an externality or a missing market. However, one of the key problems with climate change is that there are several market failures: externalities in the form of pollution from greenhouse gases; poor information; minimal incentives; the problem of the environment as a common resource and the immobility of factors of production, to name a few. Each contributes towards a misallocation of resources and prevents the welfare of society from being maximised.
When a market fails, intervention is justified and economists argue for a variety of policies to tackle the above failures. In a first-best world, there is only one market failure to tackle, but in the case of the environment, policy must be designed carefully to take into account the fact that there are numerous failings of the free market. Second-best solutions are needed. Furthermore, as the problem of climate change will be felt by everyone, whether in a developed or a developing country, international attention is needed. The two articles below are part of the Guardian’s ultimate climate change guide and consider a huge range of economic issues relating to the problem of environmental market failure.

Questions
- What is meant by market failure?
- What are the market failures associated with the environment and climate change? In each case, explain how the issue causes an inefficient allocation of resources and thus causes the market to fail? You may find diagrams useful!
- What is meant by the first-best and second-best world?
- What does a second-best solution aim to do?
- Using diagrams to help your explanation, show how a tax on pollution will have an effect in a first best world, where the only market failure is a negative externality and in a second best world, where the firm in question is also a monopolist.
- What solutions are there to the problem of climate change? How effective are they likely to be?
- Does the need to tackle climate change require international co-operation? Can you use game theory to help your explanation?!
The UK hosted the third Clean Energy Ministerial conference on 25/26 April 2012. More than 20 energy ministers from around the world attended. In his address, David Cameron, gave his backing to more wind farms being built in the UK, both onshore and offshore.
Currently just under 10 per cent of the UK’s electricity is generated from renewable sources. But to meet agreed EU targets this must increse to at least one-third by 2020. Most of this will have to come from wind.
But whilst wind turbines create no CO2 emissions, electricity generated from wind is currently some 15% more expensive than from gas. To make wind power profitable, energy companies are required by law to generate a certain percentage of their electricity from renewables and the cost is passed on to the consumer. This adds some £20 per year to the average household energy bill.
Over the coming years, many new power plants will have to be built to replace the electricity generated from older plants that reach the end of their life. So what types of plant should be built? Unfortunately measuring the costs and benefits from power generation is not easy. For a start, energy needs are not easy to predict. But more importantly, electricity generation involves huge environmental and social externalities. And these are extremely difficult to measure.
What is more, the topic is highly charged politically. The social costs do not fall evenly on the population. People might favour wind turbines, but they do not want to see one outside their window – or from their golf course!
The following videos and articles will give you some insight into the difficulties that any decision makers face in making the ‘right’ decisions about electricity generation

- Why is difficult to predict the future (financial) cost per kilowatt-hour of electricity generation by the various methods?
- Why is it difficult to estimate the demand for electricity in 10 years’ time?
- Identify the external benefits and costs of electricity generation from (a) onshore wind turbines; (b) offshore wind turbines.
- Is ‘willingness to pay’ a good method of establishing the value of external benefits and costs?
- What are the steps in a cost–benefit analysis?
- What types of problems are there in measuring external benefits and costs?
My son Andrew Sloman (see also) is currently in Goa. My wife Alison and I went to visit him over half term – our first trip to India. Goa is a beautiful state, with wonderful beaches, fantastic food and perfect weather in February. But inland from this tourist haven lies an environmental disaster caused by the open-cast extraction of iron ore.
This tiny state by Indian standards produces more than 60% of India’s iron ore exports. Whilst, along with tourism, the iron ore industry has been one of the largest contributors to the Goan economy, its environmental footprint is massive. Deforestation and water and air pollution are just three of the environmental externalities.
So should a cap be placed on the amount of iron ore that is mined? Should the industry be taxed more heavily? Should tough environmental standards be imposed on the industry? Or should it simply be allowed to continue, given its large contribution to the Goan economy? Or, at the other extreme, should the industry be closed? The linked article looks at some of the issues. Try to identify, as an economist, what information you would require in order to come to a conclusion to these questions.
Greens’ shout for cap on iron ore mining falls on deaf ears Times of India, Paul Fernandes (28/2/12)
Questions
- What negative externalities are involved with the Goan iron ore industry? Are there any positive externalities?
- What difficulties are there in measuring the negative externalities?
- How would you set about doing a cost–benefit analysis of (a) expanding the Goan iron ore industry; (b) shutting it?
- Explain the following: “The net present value of the opportunity cost for 25 years at 12% social discount rate of giving it up is greater than its environmental cost by Rs 14,449 crore, the report states.” (A crore is 10 million and Rs is the symbol for an Indian Rupee, where £1 = approximately 78 rupees.)
- What difficulties are there in attempting to take distribution into account when doing a cost–benefit analysis?
On June 20, the Review of the Government’s case for a High Speed Rail programme was published. This was commissioned by the Transport Select Committee from the independent consultancy, Oxera.
The programme is initially for a high-speed rail link form London to Birmingham and then subsequently for two additonal routes from Birmingham to Manchester and from Birmingham to Leeds. The whole thing is known as the ‘HS2 Y programme’
Oxera’s brief was to ‘provide an independent review of the economic case for the programme and to provide a set of questions that the Committee could use to probe the evidence base put forward by witnesses during its inquiry.’ In considering the economic case, Oxera focused on the economic, social and environment impacts, both monetary and non-monetary.
The summary to the report states that:
Overall, the case for the High Speed Rail programme seems to depend on whether and when the capacity is needed, the selection of the best VfM [value-for-money] approach to delivering that capacity, the degree of uncertainty around the monetised benefits and costs of the preferred options, and judgements on the balance of evidence relating to non-monetised items, such as environment and regeneration impacts (which are likely to be substantive in their own right but not fully set out in the Government’s assessment).
On July 19, the Institute for Economic Affairs, the pro-free-market think-tank, published a highly critical disussion paper, challenging the case for HS2. The paper, High Speed 2: the next government project disaster? arges that:
There is a significant risk that High Speed 2 (HS2) will become the latest in a long series of government big-project disasters with higher-than-forecast costs and lower-than-forecast benefits. HS2 is not commercially viable and will require substantial and increasing levels of subsidy. Taxpayers will therefore bear a very high proportion of the financial risks, which are wholly under-represented in the Economic Case presented by the Department for Transport.
The publication of the report and the IEA discussion paper has fueled the debate between supporters and opponents of HS2, as the articles below demonstrate.
Update
In November 2011, the House of Commons Transport Select Committee came out in favour of the government’s HS2 plans. According to the committee’s chair, Louise Ellman:
A high speed rail network, beginning with a line between London and the West Midlands, would provide a step change in the capacity, quality, reliability and frequency of rail services between our major cities.
A high speed line offers potential economic and strategic benefits which a conventional line does not, including a dramatic improvement in connectivity between our major cities, Heathrow and other airports, and the rest of Europe.
However, she did raise some issues that would need addressing concerning the overall level of investment in the rail network and the encironmental impact of HS2.
Investment in HS2 must not lead to reduced investment in the ‘classic’ rail network. We are concerned that the Government is developing separate strategies for rail and aviation, with HS2 separate from both. We call again for the publication of a comprehensive transport strategy.
Investment in high speed rail has potential to boost growth but may have a substantial negative impact on the countryside, communities and people along the route. This must be better reflected in the business case for HS2 and future phases of the project. We would encourage the Government to follow existing transport corridors wherever possible.
Further update
In January 2012, the government approved HS2. The Transport Secretary, Justine Greening, said:
I have decided Britain should embark upon the most significant transport infrastructure project since the building of the motorways by supporting the development and delivery of a new national high speed rail network.
The ‘articles for further update’ below give reactions to the announcement.

- Why are the costs and benefits subject to great uncertainty?
- How should this uncertainty be taken into account by decision-makers?
- Explain the process of discounting in cost–benefit analysis. How should the rate of discount be chosen?
- What are the main criticisms of the report made by the IEA discussion paper?
- Assess these criticisms.
Ministers from around the world met in Durban in the first two weeks of December 2011 to hammer out a deal on tackling climate change. The aim was that this would replace the Kyoto Treaty, due to expire at the end of 2012.
International climate change agreements are particularly difficult to achieve, as there are several market failures involved. Also, there is considerable ‘gaming’, as each country seeks to negotiate a deal that benefits the world as a whole but which minimises the disadvantages to their own particular country.
The conference ended on the 11 December with a last-minute deal. Both developed and developing countries would for the first time work on a legally binding agreement to limit emissions. This would be drawn up by 2015 and to come into force after 2020. The following articles assess the significance of the agreement and whether it represents real progress or little more than a deal to work on a deal.
