It is widely acknowledged that the supply of oil and gas will eventually run out. As these resources are depleted, prices will inevitably rise. However, with heating and energy bills at extremely high levels, a new ‘resource’ in Sweden has been used to heat buildings: Body Heat!
Hundreds of thousands of people pass through Stockholm Central Station every day and rather than letting the body heat these people generate go to waste, a Swedish firm, Jernhusen, is now ‘collecting’ their heat, converting it into hot water and then using this as a new heating resource. Klass Johnasson, one of the creators of the system said:
This is old technology being used in a new way. The only difference here is that we’ve shifted energy between two different buildings.
The Swedish firm has found that the system is not only environmentally friendly, but it is also good business practice, as it has reduced the energy costs of the block by some 25%, which, during a recession and with high energy prices, is no small thing!
The costs and benefits of such a system will inevitably vary from country to country, but in Sweden’s case, it is a viable method of heating, given their high energy prices and low winter temperatures. They are not stealing the heat from anyone, but are simply converting the excess heat that is already there. Obviously, the fact that the firm owns the station, and also the land between the station and their building, is helpful in ‘transferring’ the energy, but the firm argues that even if this wasn’t the case, it’s nothing co-operation wouldn’t solve. Is this the future of low-cost and low-carbon heating?

Questions
- Think about how we define abundance. Is body heat an abundant resource?
- Why are energy and oil prices so high? How does scarcity affect their price?
- Could this source of heating be described as a market failure? If so, how could we illustrate this on a diagram?
- Consider the Swedish firm’s profit-maximising price and output. The new heating method is said to reduce their costs – will it affect their average and/or marginal costs? Show the impact on a diagram. What happens to the firm’s profits?
- Is this heating method something other firms could benefit from? How could they decide whether it is cost-effective?
- Is there a role for the government to encourage more firms to use this method? Explain your answer.
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?
For most people, buying a new car is a luxury and in times of hardship it is a luxury that many cannot afford. Sales of new cars did grow during 2010 by 1.8% compared to the previous year, although the end of the car scrappage scheme in March 2010 did see a fall in sales. Sales went from being 19.9 per cent up on 2009 in the first half of the year, to being 13.8 per cent down for the remainder of 2010. On top of this, they are predicted to fall by some 5% over the coming 12 months.
Part of the explanation of this trend is the VAT rise. While an extra 2.5% is hardly noticeable on many every day items (as we saw when VAT was reduced to 15%), it will have a much larger effect on more expensive items, such as cars.
It was expected that people thinking of buying a new car would try to beat the VAT rise and so car firms hoped for a surge in sales during December. However, this did not occur and with VAT at 20% during 2011, car prices will rise: a £15,000 car will cost an extra £320. Another contributing factor to the lower than expected sales in December was the snow. Retail sales in December collapsed by 37.5%, where as fleet sales, which are less likely to be affected by the adverse weather rose by 5.1%. Similar patterns were seen in Spain, Italy and France, but in Germany sales were up by 7% on the year from December 2009.
The good news for the UK car industry is that the second half of 2011 is expected to see growth, so there may be some recovery. Furthermore, UK-built cars have seen a rise in sales – up by 17%. Finally, as petrol prices continue to rise, it is hoped that this might encourage people to trade in their less efficient old cars for more fuel-efficient new cars. This will certainly be an industry to watch over the next few months.

Questions
- What type of tax is VAT? Illustrate the effect of such a tax on a diagram and explain why the higher the price of the good, the bigger the impact of the VAT rise. How might this impact inflation?
- Why are car sales expected to fall in the UK over the coming year? Given this expected trend, what might we expect to see in terms of car prices?
- What impact might rising petrol prices have on new car purchases? What figure would you expect to see for cross elasticity of demand?
- How might the expected decline in car sales affect the UK economy over the next 12 months?
- What type of market structure is the car industry? (Think about the characteristics of monopolistic competition and oligopoly.)
- How did the car scrappage scheme help car sales?
- What might explain the different trend seen in the German car industry?
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?

There has been a 38% increase in profit margins made by energy companies in the last 2 months and it is this which has prompted an investigation by Ofgem, the electricity and gas market regulator in the UK. Alistair Buchanan, Ofgem’s chief executive, said:
“With Britain facing an investment bill of £20bn over the next 10 years, consumers have the right to expect that the energy retail market is providing them with value for money. Our analysis published today shows an increase in company margins from £65 to £90 at a time of rising energy prices, which causes Ofgem to rightly ask if companies are playing it straight with consumers.”
Three of the big six suppliers have recently announced price rises and the fast-track review by Ofgem will consider whether consumers should be better protected. Scottish Power has increased gas prices by 2% and electricity prices by nearly 9%, meaning some customers may pay an extra £138 per year. British Gas is also planning on raising prices from December 10th, with gas and electricity bills expected to increase by 7%. Scottish and Southern Energy said it will increase domestic gas tariffs by 9.4%. EDF has promised a price freeze – at least until after the winter and nPower and E.ON are yet to announce their plans, but we can expect some form of a price rise.
While the review won’t make any difference to customer bills in the short term, Ofgem does have the power to make some changes to the way the companies are run. It is also expected that Ofgem will ask for more legislative support from the government and the Competition Commission. Although there are several suppliers in the energy market, each has market power and their dominance is preventing new firms from entering. As Adam Scorer, Director of Reputation and Impact at Consumer Focus, said:
“They do not feel the hot breath of competition on their necks.”
