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.
It is the Bank of England’s responsibility to ensure that inflation remains on target. They use interest rates and the money supply to keep inflation within a 1% band of the inflation target set by the government = 2%. However, for the past 12 months, we have had an inflation rate above the 3% maximum and this looks set to continue. Official figures show that the CPI inflation rate has risen to 3.3% in November, up from 3.2% in October 2010 – above the inflation target. There was also movement on the RPI from 4.5% to 4.7% during the same months. The ONS suggests that this increase is largely down to record increases in food, clothing and furniture prices: not the best news as Christmas approaches. It is not just consumers that are facing rising prices, as factories are also experiencing increasing costs of production, especially with the rising cost of crude oil (see A crude story). Interest rates have not changed, as policymakers believe prices will be ‘reined in’ before too long.
However, the government expects inflation to remain above target over the next year, especially with the approaching increase in VAT from 17.5% to 20%. As this tax is increased, retail prices will also rise and hence inflation is likely to remain high. There is also concern that retailers will use the increase in VAT to push through further price rises. A report by KPMG suggests that 60% of retailers intend not only to increase prices to cover the rise in VAT, but to increase prices over and above the VAT rise.
Despite the planned VAT rise spelling bad news for inflation, it could be the spending cuts that offset this. As next year brings a year of austerity through a decrease in public spending, this could deflate the economy and hence bring inflation back within target. However, there are suggestions that more quantitative easing may be on the cards in order to stimulate growth, if it appears to be slowing next year. The Bank of England’s Deputy Governor, Charles Bean said:
“It is certainly possible that we may well want to undertake a second round of quantitative easing if there is a clear sign that UK output growth and with it inflation prospects are slowing,” Bean told a business audience in London.”
The following articles consider the rising costs experienced by firms, the factors behind the inflation and some of the likely effects we may see over the coming months.

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.

- 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?
As students, many of you probably have a student identification card, which you might use when you go to the cinema or when you buy something in a shop offering student discounts. Your parents or grandparents, if they are 60 or over, may get similar discounts, and your younger siblings or nieces and nephews may pay nothing for certain services.
It doesn’t cost a cinema more to provide a seat for an adult than it does for a child, a student or a senior citizen. So, why is it that firms can charge different groups of consumers different prices, even though they are consuming the same good or service? We are, of course, referring to the ability of a firm to price discriminate. The following short cases look at the concept in action.

GDP (or Gross Domestic Product) measures the value of output produced within a country over a 12-month period. It is this figure which we use to see how much the economy is growing (or shrinking). We can also look at how much different sectors contribute towards this figure. Over the past few decades, there has been a significant change in the output of different sectors, as a percentage of GDP, within the UK economy. In particular, the contribution of manufacturing has diminished, while services have grown rapidly.
However, there is one specific area that is making a growing contribution towards UK GDP and is expected to see acceleration in its growth rate by some 10% annually over the next few years: the internet. Although the internet is not an economic sector, the Boston Consulting Group (BCG) said that if it was, it would be the UK’s fifth largest sector and according to a report by Google, it is worth approximately £100 billion per year to the UK economy. Furthermore, it is an area in which the UK is one of the leading exporters. The emergence of the internet has transformed industries and individual businesses and the trend looks set to continue. The report by Google found that some 31 million adults bought goods and services online over the past year, spending some £50 billion.
What are the benefits for businesses of internet shopping and does it have an impact on the retail outlets on Britain’s highstreets? The answer is undoubtedly yes, but is it good or bad? What does the emergence of this new ‘sector’ mean for the UK economy?
