The law of demand tells us that when the price of a good falls, quantity demanded will rise. But, firms want to know much more than this. They need to know by how much quantity demanded will rise – we refer to this as the price elasticity of demand (PED) and we can categorise it as relatively inelastic or elastic, depending on by how much demand changes relative to the change in price. The price elasticity of demand is crucial for a firm to know, as it gives them vital information about the best price to charge and getting the price right is probably the most important element in a successful business. As Warren Buffett said in a meeting with the staff from the Federal Crisis Inquiry Commission:
‘Basically, the single most important decision in evaluating a business is pricing power. You’ve the power to raise prices without losing business to a competitor, and you’ve got a very good business. And if you have to have a prayer session before raising the price by a tenth of a cent, then you got a terrible business.’
The grammar may not be entirely correct, but hopefully you get the gist! Should a firm increase price or reduce it? Whatever action it takes, there will be an effect on demand, total revenue and profit. The key question is: what will be the effect? The answer depends on the PED.
If a firm is selling a product for which there are no close substitutes, we would expect demand to be relatively inelastic. This means that the firm can increase the price it charges without seeing any large fall in quantity. On the other hand, if a firm faces a lot of competition and hence there are many substitutes for a product, then demand becomes much more elastic – any increase in a firm’s price will lead to a proportionately larger decrease in the quantity demanded, as customers will simply switch to a cheaper alternative. The article below looks at the concept of price elasticity of demand and how it is used in practice by competing firms.

The snow the UK has seen over the past two winters created massive disruption, but that is only one reason for hoping for a milder winter to come. With the cold weather, the UK economy faced threats of gas shortages, as households turned on their heating. However, despite the freezing temperatures, many households were forced to turn off their heating regularly, due to the excessive bills they would face. This trend is expected to be even more prevalent if the 2011/12 winter is as cold, as fuel tariffs are predicted to rise. The Bank of England has said that gas and electricity prices could rise this year by 15% and 10% respectively. British Gas’s Parent company, Centrica said:
“In the UK the forward wholesale prices of gas and power for delivery in winter 2011/12 are currently around 25% higher than prices last winter, with end-user prices yet to reflect this higher wholesale market price environment.”
These predictions might see the average UK household paying an extra £148 over the next year. Although these are only estimates, we are still very likely to see many households being forced to turn off their heating. One thing which therefore is certain: a warmer winter would be much appreciated!

Are we heading for ‘perfect storm’ in commodity production and prices? Certainly the prices of many commodities have soared in recent months. These include the prices of foodstuffs such as dairy products, cooking oils and cereals, crude oil, cotton, metals and many other raw materials. The overall world commodity price index has risen by 28% in the past 12 months. The following are some examples of specific commodities:
Price rises in the 12 months to February 2011
• Wheat 62%
• Maize 59%
• Coffee 70%
• Beef 39%
• Sugar 46%
• Palm kernal oil 142%
• Soybean oil 50%
• All food price index 32%
• Crude oil 20%
• Cotton 132%
• Fine wool 55%
• Softwood timber 25%
• Iron ore 78%
• Copper 29%
• Tin 55%
• All metals index 58%
• Rubber 79%.
The problems are both short term and long term, and on both the demand and supply sides; and the effects will be at micro, macro and global levels. Some hard choices lie ahead.
The following webcast, articles and reports explore both the current position and look into the future to ask whether rising commodity prices are likely to continue or even accelerate.
The first link is to a BBC World Debate which considers the following issues: “Is scarcity of natural resources a serious challenge for developing and advanced economies? How great is the risk that scarcity might lead to conflict, both within and between nations? Might a scramble for resources lead to a retreat from globalisation and to greater protectionism?”

Oil is a commodity like any other – its price is affected by demand and supply. Back in 2003, with the impending war in Ira and strikes in Venezuela, oil prices increased and continued to do so as further supply concerns developed in Saudi Arabia, Russia and Nigeria. This upward trend continued until 2008, when with the growing banking turmoil and demand for oil falling, the price began to decline. However, the crisis in Libya is only making matters worse. Its credit-rating has been downgraded with the potential for it to be lowered further and concerns are deepening about the country’s crude exports. As Libya is the world’s 12th largest exporter of oil, these supply concerns have started to push up oil prices once more.
With inflation rates already high and political turmoil pushing oil prices up further, consumers and firms are feeling the squeeze. These changes have also been reflected on stock markets across the world. Analyst, Michael Hewson at CMC Markets said:
‘Given the fact that we have seen massive gains in stock markets over the last few months, investors have been nervous about a possible correction for some time… The tensions in the Middle East with Libya imploding and concerns that the unrest could spread to Saudi Arabia could provide a catalyst for (this) correction.’
The disruption in the Middle East has caused companies such as Eni of Italy and Repsol YPF of Spain to shut down production, leading to output losses of some 22% of Libya’s production. As supply contracts from this region, prices will inevitably rise. However, the Saudi oil Minister has said that he is ready to boost production to offset any decline, but that at present there is no oil crisis. So, what can we expect to happen to oil prices in the coming months? It will all depend on changes in demand and supply.

Demand and supply determine prices, but when it comes to factors of production, such as labour, their ‘price’ is largely influenced by their productivity. This helps to explain why doctors are paid more than cleaners and Premiership footballers more than amateurs. But, can it really explain a £50 million transfer price for Fernando Torres, as he moves from Liverpool to Chelsea? Undoubtedly he’s a good footballer, but are his skills worth the price paid? The same question can be asked about David Luiz – a price of £25 million; Andy Carroll – a price of £36 million and a bargain price for Luis Suarez – a mere £23 million! How can teams, such as Chelsea afford to spend so much money, despite making a loss of £70.9 million in the year to June 2010? How much would they have lost had they not won the Premier league and the FA cup?
With the country facing the possibility of returning to recession and the trouble that Portsmouth FC found itself in last season, UEFA’s ‘financial fair play’ rules seemed like a good idea. But, they appear to have been thrown out the window. £200 million was spent on a handful of footballers, as libraries across the UK are shut down due to a lack of funds. The Premier League in the UK generated a higher income than any other, equal to £2.3 billion. However, 14 of our clubs made substantial losses. The amount owed to banks or the owners backing these clubs came in at a mere £3 billion. As the big clubs in the UK push up the prices, more and more ‘small’ clubs are being competed out of the market.
