Here’s an interesting example of oligopoly – one you probably haven’t considered before. It’s the art market. And it’s not just one market, but a whole pyramid of markets. At the bottom are the ‘yearning masses’ of penny-poor artists, from students to those struggling to make a living from their art, with studios in their attic, garden shed or kitchen table. At the top of the pyramid are those very few artists that can earn fantastic sums of money by selling to collectors or top galleries. Then there are all the layers of markets in between, where artists can earn everything from a modest to a reasonable income.
The pyramid is itself depicted as a work of art, which you can see in the linked article below. It’s worth studying this piece of art carefully as well as reading the article.

Questions
- Identify the increasing barriers to entry as you work up the art market pyramid.
- Are there any other market imperfections in the art market that you can identify from the diagram?
- What are the key differences between the ‘primary market, tier 1’, the ‘primary market, tier 2’ and ‘the secondary market’?
- Are artists ‘rational maximisers’? If so, what is it they are trying to maximise? If not, why not?
- How would you set about determining the ‘worth’ of a piece of art? How do possible future value of a piece of art determine its present value?
Market failure occurs when the free market fails to deliver an efficient allocation of resources. Pollution by cars is a prime example of a negative externality or an external cost. We pay road tax and face high tax rates on petrol, but another form of government intervention is due to come into effect. From the 1st January 2011, nine models of electric car will be eligible for grants of up to £5000 (although only three models will be immediately available). By subsidising certain electric cars, the government is aiming to give people an incentive to switch to these so-called more environmentally friendly cars, as they will now be cheaper.
There are concerns, however, that generating the electricity to charge these cars still emits carbon dioxide. The Transport Secretary, Philip Hammond, said:
There’s no point in switching the car fleet to running on electricity if the electricity emits vast amounts of carbon dioxide.
So is the electric car the car of the future?

Questions
- What is the purpose of a subsidy? Using a diagram explain how it will work and what the impact should be.
- Why is pollution an example of a market failure? Illustrate this on a diagram.
- Why could electric cars also be an example of a market failure? Illustrate this on a diagram.
- How will the subsidy aim to encourage more firms to produce electric cars and also more consumers to buy them?
- Is there an argument for increased investment in technology to produce electric cars more cheaply and more effectively?
- Why is there such a high demand for car usage?
A two-week international climate change summit opened in Cancún, Mexico, on 29 November. But will the talks make any progress in tackling global warming? Will mechanisms be put in place to ensure that the previously agreed ceiling of 2°C warming is met?
After the largely unsuccessfuly talks in Copenhagen a year ago, hopes are not high. But a likely rise in global temperatures of considerably more than 2°C could have disasterous global consequences. Indeed, new evidence suggests that even a ceiling of 2°C may be too high and that, as temperatures rise towards that level, domino effects will start that may become virtually unstoppable. As Andrew Sims in the Guardian article notes:
This is the problem. Once the planet warms to the point where environmental changes that further add to warming feed off each other, it becomes almost meaningless to specify just how much warmer the planet may get. You’ve toppled the first domino and it becomes virtually impossible to stop the following chain of events. Honestly, nobody really knows exactly where that will end, but they do know it will end very, very badly.
The following podcasts and articles look at the importance of reaching international agreement but the difficulties of doing so.

Questions

- What can governments do to internalise the externalities of greenhouse gas emissions?
- What insights can game theory provide into the difficulties of reaching binding climate change agreements?
- What are likely to be the most effective mechanisms for getting people to adapt their behaviour?
- Can nudge theory be used to change our habits towards the environment?
- Explain the use of equity weights in judging the effects of climate change. Are they a practical way forward in devising environmental policy?
You might think that small environmentally-friendly companies would be moving into the green energy market: that setting up a wind farm, for example, would be a perfect business opportunity for a small company. In fact, the big companies are taking over this market. As the Der Spiegel article below states:
Europe’s wind energy sector is currently experiencing a major transformation. New massive offshore wind parks are soon expected to crop up off Europe’s coastline. Big companies like Siemens and General Electrics are increasing their stakes in a market worth billions. But experts warn that a new energy oligopoly may soon emerge.
So what is it about the wind energy market that makes it suitable for an oligopoly to develop? The two articles explore this question.

Questions
- What market failures are there in the wind energy market?
- What barriers to entry are there in the wind energy market?
- What economies of scale are there in this market?
- How are changes in this market affecting the minimum efficient scale of companies?
- Would there be room in the market for enough competitors to prevent collusion?
- How might the authorities prevent (a) open and (b) tacit collusion in the wind energy market?
- Do small wind energy companies have any market advantages?
Student fees are set to rise to between £6000 and £9000 per year from 2012 (see Will students be Browned off?. But I’m sure you know that already! Not surprisingly, there has been considerable debate about the effects on student debt and whether potential students will be put off from applying to university. But there is another issue, explored in the article below. This is the question of the ‘marketisation’ of higher education.
With the exception of the STEM subjects (science, technology, engineering and maths) universities will no longer receive any teaching subsidy from the government. Teaching will have to be funded from student fees. This means that provision will depend on supply and demand. If there is a high demand for certain courses, then the courses will be financially viable for universities. If not, they will have to close (unless the university chooses to cross-subsidise them from other profitable courses).
This might be fine if the market for university places were perfectly competitive and if questions of inequality of access were fully taken into account. But the higher education market is not perfect. The article looks at some of these imperfections and why, therefore, a pure market system will fail to achieve the optimum allocation of university places.
Browne’s Gamble London Review of Books, Stefan Collini (4/11/10)
Questions
- What information failures are there in the market for higher education places?
- What externalities are involved in higher education and will this lead to an over or underprovision of higher education in a pure market system?
- Apart from externalities and information asymmetries, what other market failures apply to the market for student places in HE?
- What are the arguments for subsidising non-STEM subjects (as well as STEM ones)? Should these subsidies vary from course to course and from university to university?
- What is the best way of tackling the problem of unequal access to higher education?
