One of the interesting things about the recent recession was the dilemma that it posed for governments. As aggregate demand fell, unemployment rose, incomes fell, which reduced demand further and so national output began to decline. Obviously there were many other factors contributing to this decline, in particular the housing market, but the long and the short of it is, aggregate demand was falling. With the AD curve shifting inwards, we would expect the average price level to fall at the same time: i.e. inflation doesn’t tend to be much of a problem during a recession. It is this fact that posed something of a dilemma. In the recession, not only was aggregate demand low, but inflation was rising. The explanation for this: in large part due to rising commodity prices – a supply-side shock. Governments had to deal with low national output and inflation: this combination made policy changes much more complex.
While prices for many goods and commodities did fall significantly after their peak in 2008, there has been a gradual rise again and there seems to be no end in sight. Headline food prices, in particular, have increased almost to their 2008 levels, although in real terms prices are still lower. Onions in India; cabbage, pork and mackerel in South Korea; chillies in Indonesia – the list goes on. The rapidly rising prices of these basic foodstuffs has, in many cases, led to emergency government intervention. However, there are fewer concerns this time round, as many hope that the causes of these higher prices are not just the increases in demand but crucially temporary supply shocks. Bloomberg’s Businessweek Assistant Managing Editor, Sheelah Kolhatkar, said:
There are a lot of reasons [for rising prices]. Weather is cited as a big one. There’s been sort of freak weather in different parts of the world. Russia experienced a drought. There are floods in Australia. There’s been sort of freezing weather in Florida. Our own Midwest experienced flooding earlier this year. And because the market for a lot of these food commodities is global, when something strange happens somewhere, that can affect a crop.
On the other hand, there are growing concerns at the timing of this inflation: the developed world has barely escaped from recession. How is it that inflation can already be a problem? Furthermore, with loose monetary policy in many countries, rising food and commodity prices could continue for some time.
An interesting question to consider is which countries will be affected the most? In Britain, like other developed countries, food consumption accounts for between 15 and 20 per cent of a household budget. However, in developing countries, food can take up between 50 and 75 per cent of a houshold budget, so any rise in food prices is disastrous.
What does it mean for the recovery? Well, if food (a necessity) is increasing in price, households have little choice but to pay the higher prices. This means they have less disposable income for other goods, hence aggregate demand may be adversely affected. The following articles will hopefully give you some ‘food for thought’!

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.
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?
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?
