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?!
A recent post on this blog referred to what sounds a fascinating new book, What Money Can’t Buy: The Moral Limits Of Markets, by Michael Sandel. The Guardian also recently featured an extract from this book.
As the earlier blog post discussed, our lives are now dominated by markets. Economists typically believe markets are the best way to allocate resources as, if the market mechanism works correctly, the resulting equilibrium maximizes economic welfare as measured by the sum of consumer and producer surplus. In particular, all consumers that are willing to pay a price above the market price are able to buy the product.
Fundamental to the measurement of consumer welfare is the notion that consumers will be prepared to buy a product as long as their willingness to pay exceeds the price. It therefore follows that consumers are more likely to buy the product as the price falls and, if they do so, gain increasing surplus. However, the extract from Michael Sandel’s book provides a number of interesting examples which suggest that in some situations this might not be the case.
One example concerns the storage of nuclear waste in Switzerland. When surveyed, 51% of the residents of the small Swiss village of Wolfenschiessen, said that they would be prepared to accept the waste being stored nearby. However, somewhat surprisingly, this figure fell to 25% when the residents were told that they would be compensated for the inconvenience. Furthermore, the figure remained at this low level even when the proposed compensation was increased to over £5000 per person.
Sandel argues that this is because, once compensation is introduced, financial incentives crowd out public spirit. He suggests that:
putting a price on the good things in life can corrupt them.
For economists, this potentially has important implications for how we evaluate market outcomes and our belief that the market equilibrium is always the optimal outcome. Furthermore, it suggests that in some circumstances allowing the market mechanism to allocate resources may not be the ideal solution.

Questions
- How is consumer surplus calculated?
- How does the market mechanism allocate resources?
- How would you explain the responses of the residents in the Swiss village?
- Do you think the Swiss residents would respond in the same way if the compensation offered was increased even further?
- What type of products and services do you think might be less well suited to being provided by markets?
Here’s a question that goes to the heart of economics and the social sciences generally: how desirable is the market system?
Our lives are dominated by markets. Whether in working or consuming, we operate in a market economy in which money is exchanged for goods or services. But also financial and product markets determine much of the structure of society, where most things seem to have a price.
But whilst, as a positive statement, we can say that money and markets are all around us, does that make them desirable? Markets provide signals and incentives; but are the signals the right ones? What are the incentives and how do we respond to them? And are these responses optimal?
You will probably have studied various ways in which markets fail to provide the optimal allocation of resources. But what are the limits of markets as a mechanism for social choices? And is there some more fundamental issue about the morality of a society that is organised around markets?
These are questions considered in the following podcast. It is an episode from BBC Radio 4’s Start the Week programme, hosted by Andrew Marr, with guests Michael Sandel, Diane Coyle and Grigory Yavlinksy. Here are the programme details:
Andrew Marr discusses the relationship between markets and morals with the political philosopher Michael Sandel. In his latest book, What Money Can’t Buy, Sandel questions the dominance of the financial markets in our daily lives, in which everything has a price. But the economist Diane Coyle stands up for her much maligned profession, and points to the many benefits of a market economy. The Russian economist Grigory Yavlinksy argues against viewing the world of money as separate from culture and society: he believes the financial crisis was merely a symptom of a wider moral collapse, and that it is time to examine the way we live.

- What, according to Michael Sandel, is the difference between a market economy and a market society?
- Is the market society a relatively new phenomenon, or does it go back hundreds of years?
- To what extent is the greed expressed through markets and encouraged by markets affecting/infecting society and human relationships generally?
- What is the role of morality and trust in determining the desirability of market relationships?
- To what extent does a market economy allow people, rich and poor, to live separately from each other and not interact as joint members of society?
- What are the value systems promoted by marketisation? Should certain aspects of human life be outside these value systems?
- To what extent is the crisis of capitalism a crisis of economics?
- What policy alternatives are there for rebalancing society?
- What is the role of economists in advising on policy alternatives?
The Office for Budget Responsibility has said that the UK Treasury will face a shortfall of £13bn in motoring taxes within a decade. Although car usage continues to rise putting increasing pressure on the road infrastructure, the greener and more fuel efficient cars being produced are driving down the tax revenues generated from motoring.
A report by the IFS has put forward the case for replacing the existing system of taxes on cars and fuel by a new road charging system. If no such change occurs, the IFS has forecast that with more electric cars and hence lower revenues raised from fuel and vehicle excise duties, the shortfall facing the Treasury would require an increase in fuel duty of some 50%. Instead of this, the solution could be to charge individuals for every mile of road they use, with the ‘price’ varying depending on the degree of congestion. For example, at peak times the price would be higher, where as for those in the countryside where roads are traditionally much quieter, charges would be lower. The IFS said:
‘Such a move would generate substantial economic efficiency gains from reduced congestion, reduce the tax levied on the majority of miles driven, leave many (particularly rural) motorists better off, and provide a stable long-term footing for motoring taxes without necessarily raising net additional revenue from drivers.’
Government policy across the world has been increasingly focused on climate change, with targets for emissions reductions being somewhat ambitious. However, many car manufactures who were told to reduce emissions significantly are on the way to meeting these targets and this success is a key factor contributing towards this new road ‘crisis’ that could soon be facing the government. The following articles consider the possibility of a road charging scheme.

Questions
- Illustrate the effect of a tax being imposed on petrol. What happens to the equilibrium price and quantity?
- Despite fuel duty pushing up the price of petrol, why has there been such a small decline in the quantity of petrol individuals use?
- Evaluate the case for and against a road charging scheme.
- Why are tax revenues from motoring expected to decline over the next decade?
- Climate change has become an increasingly important focus of government policy. To what extent is the current road ‘crisis’ a positive sign that policies to tackle climate change are working?
- If a road charging scheme went ahead and prices were varied depending on traffic, time etc, what name would you give to this strategy?
- Why would it be possible to charge a higher price at peak times and a lower price for cars using country roads?
- Is there an argument for privatising the road network? Is it even possible?
Binge drinking is a problem that has seen much attention, especially with regards to minimum price controls. However, in this blog, we consider attention in this sector concerning taxation on beer.
Alcohol is widely considered to be a de-merit good with negative externalities imposing external costs on society. This is one of the reasons why taxes are imposed on alcoholic beverages. By increasing production costs to the firms providing these drinks, prices rise and hence the policy aims to discourage consumption.
During the recession, many businesses have seen demand fall and one sector hit particularly hard because of this and very high tax rates has been the local pub community. Duty on beer has increased since 2008 by some 42%. As such, many rural and suburban communities have seen their local watering holes close down and this has led to a campaign by CAMRA to force a debate in Parliament, as a means of protecting ‘one of Britain’s oldest and best loved institutions’. Data suggests that 12 pubs per week are closing down, thus the future of the industry is now under threat. This may also have further damaging effects on local communities, as it may adversely affect the social aspect of communities. Camra’s Chief Executive, Mike Benner said:
‘Whether situated in a small village, city high street, or on the edge of a housing estate, pubs are so central to our society that whole communities can grow around a particular pub.’
According to a study, pubs in Lancashire and the West Midlands have been hardest hit by the pub closures. If pubs don’t pass the tax increase on to consumers in the form of higher prices, then they must bear the burden. If they do pass the tax rises on to consumers then the larger chain firms can increase their market share by selling at a lower price. They are also facing growing pressure from the supermarket industry, which are able to sell cheap alcohol, also contributing to going to the pub becoming an ‘unaffordable activity’. The following articles consider this industry.

- In this market, would the tax be more likely to be borne by the producers or consumers? Explain your answer and illustrate on the previous diagram why this is the case.
- Why are supermarkets able to compete local pubs out of the alcohol market? Do you think a minimum price will have any effect?
- What is a de-merit good? Illustrate the concept of a negative externality on a diagram.
- Explain how a de-merit good causes the market to fail. To what extent does the tax on beer solve the market failure?
- Why are there likely to be adverse effects on local communities? Could this have an adverse effect on economic activity in the area?
