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

  1. Think about how we define abundance. Is body heat an abundant resource?
  2. Why are energy and oil prices so high? How does scarcity affect their price?
  3. Could this source of heating be described as a market failure? If so, how could we illustrate this on a diagram?
  4. 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?
  5. Is this heating method something other firms could benefit from? How could they decide whether it is cost-effective?
  6. Is there a role for the government to encourage more firms to use this method? Explain your answer.

$8 billion – this is the likely cost of the BP oil leak, which spilled 206 million gallons of oil into the Gulf of Mexico. Whilst the oil leak has been stopped for some time, there were ongoing concerns that the leak would re-appear due to the underwater pressure. The cost of stopping the leak has been substantial, but BP will face further costs, as the company begins to pay out compensation.

$20 billion is the compensation that residents of the Gulf of Mexico will receive. Further to this, BP has said that it will invest more money in promoting the tourism industry there, which has suffered from the oil spill. However, what about the fishing industry? Although compensation will be paid for the losses incurred, will this continue in the long term? The oil may cause a loss in productivity in certain populations of sea-life. How will this impact us? If certain fish became scarcer, then their price will rise accordingly, whether you purchase the fish at a shop or have it as a meal in a restaurant. To make matters worse, the hurricane season has arrived in the affected areas, which will make the clean-up effort even harder.

As BP’s share price has fallen, individuals have suffered from lower dividends. Jupiter Income Trust had almost 10% of their portfolio invested in BP, which largely explains the 9 per cent drop in their payout.

The annual Agricultural Outlook for the next ten years has just been published jointly by the OECD and the UN Food and Agriculture Organization (FAO). Click here and here for audio presentations of the report by the FAO’s Jacques Diouf and the OECD’s Angel Gurría.

The report argues that world recovery will raise agricultural prices. This will be partly the direct result of higher demand and partly the result of higher prices of agricultural inputs, such as fertilisers and fuel. But prices will not rise back to the peak levels of 2007/8. These higher prices, however, would have a positive effect on world food output, especially in the BRICs (Brazil, Russia, India and China). This, in turn, would limit the price rises.

So is this good news for food producers and consumers? The following articles look at the issues

Questions

  1. Explain what is likely to happen to food prices. What are the explanations given in the report?
  2. Represent the analysis on a supply and demand diagram (or diagrams).
  3. What is the relevance of (a) income elasticity of demand, (b) price elasticity of demand, (c) cross-price elasticity of demand, (d) price elasticity of supply, in explaining the likely future movements of food prices and why some food prices are likely to rise faster than others?
  4. What factors are likely to impact on the production of food in developing countries?

As the global recession began to take hold during 2008, so many commodity prices plummeted. Oil prices fell from over $140 per barrel in mid July 2008 to around $35 per barrel by the end of the year (a mere quarter of the price just 6 months previously). From early 2009, however, prices started rising again and have continued to do so during 2010. By mid April 2010, the price of oil had risen to $85 per barrel.

And it’s not just oil prices that have been rising. The prices of metals such as copper, nickel and zinc have been soaring. Since the beginning of February 2010, copper prices have risen by 18%, zinc prices by 20% and nickel prices by 46%. As the article from the Independent states:

The Office for National Statistics said that the input price index for materials and fuels purchased by the manufacturing industry rose 10.1 per cent in the year to March and rose 3.6 per cent between February and March alone. The ONS added that prices of imported materials as a whole, including imported crude oil, rose 4.4 per cent between February and March.

Much of the explanation for this has been the global recovery. But while raw material prices have been rising, grain prices have been relatively steady and recently have fallen. So how can this be explained? The answer, as always with commodity prices, lies with demand and supply, as you will see when you read the following articles.
