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.

Up until a year ago, milk and cheese prices were soaring woldwide (see Cheddar – the king of cheeses at £2000 per tonne). A surging world economy and rapidly growing demand from China and India were driving up commodity prices, including milk and milk-based producs. In the UK, average farmgate prices for milk had risen from 19 pence per litre (ppl) in 2006 to 27.4ppl by October 2008 (see here for data). Since then, however, as the global economy has plunged into recession, milk prices have fallen. By September 2009, the farmgate price had fallen by over 18 per cent to around 22.4ppl. With rising costs for fuel and cattle feed, many dairy farmers are now making a loss and are either quitting, or considering quitting, the industry.
It’s a similar story in Europe, North America and other dairy producing regions of the world. In Europe “the mood is turning sour. Last week 300 tractors dragged milk containers over fields in southern Belgium, dumping a day’s worth of production (see video). Similar protests were made in Germany, France, the Netherlands and Luxembourg. The crisis has driven many EU farmers into a ‘milk strike’, with thousands refusing to deliver to the industrial dairy conglomerates that produce everything from skimmed milk to processed cheese.”
So is this just market forces in action and will prices rise again as the world economy recovers? Or is it a reflection, in part, of the monopsony power of the supermarkets and the milk processing industry? The following articles look at the issues, both in the UK and the rest of Europe and in the USA.

Questions
- For what reasons are many dairy farmers now making a loss?
- For what reasons has the power balance in the wholesale milk market shifted towards milk purchasers (such as supermarkets) and away from farmers?
- How would a phased liberalisation of EU milk production help the UK’s dairy farmers?
- Discuss the likely effectiveness of the European Commission’ proposed measures to help dairy sector in short, medium and long term.
- What is likely to happen to milk prices over the next two years and what will be the likely effect on supply? Explain your answer and consider the relevance of price elasticity of supply.
- “Agriculture officials and farmers in Vermont, New Hampshire and Massachusetts have launched a program called Keep Local Farms. … Organizers say they hope to appeal to consumers’ growing taste for local foods” (see final linked article above). What determines the likely effectiveness of such ‘buy local’ movements? What incentives are there for people to buy local? If countries in general encourage people to buy local, is this a zero sum game? Explain.
The US Institute of Medicine of the National Academies has recently published a 92-page on report on childhood obesity and the use of taxes on junk foods to tackle the problem. In the report, titled Local Government Actions to Prevent Childhood Obesity, “a panel of experts suggested such taxes could play an important role in helping children make healthier eating choices”.
Meanwhile, in Australia, the Federal Government’s preventive health taskforce argued, amongst other things, that “junk food advertising should be phased out, the cost of cigarettes should be more than $20 a packet, and soft drinks and cask wine should be hit with higher taxes”.
So how effective are higher taxes in achieving a reduction in ill health associated with eating, drinking and smoking? If adopted, what is the socially optimum design and rates of such taxes? What other complementary policies could be adopted? The following articles consider the issues.

- What other policies would you advocate to tackle the problems associated with consuming unhealthy products? How would they affect the price elasticity of demand for such products.

Tea prices have soared in recent months. Explanations can be found on both the demand and supply side. But while this might be bad news for tea drinkers, the news is more mixed for tea growers.
