Tag: income elasticity of demand

This autumn has been one of the mildest on record. Whilst this may be very nice for most of us, certain industries have been suffering. For example, gas and electricity consumption is down as people delay turning on their heating. One sector particularly badly hit has been clothing. Sales of winter clothes are substantially down and many retailers are longing for colder weather to boost their sales.

Of course, this is not helped by consumer incomes. With inflation at around 5% and average (pre-tax) weekly earnings currently rising by less than 2%, real incomes are falling. In fact over the year, even nominal disposable incomes are down 2.1%, given the rise in national insurance and income tax. And the problem of falling incomes is compounded by worries over the future state of the economy – whether it will go back into recession, with further falls in real income and rises in unemployment.

It’s no wonder that retailers are longing for some cold weather and for their customers to return from the seaside or their garden barbecues to the shopping malls. Look out for the ‘sales’ signs: they’re beginning to spring up as desperate retailers seek to attract wary customers.

With pressure on household incomes, many have had to forego spending on luxuries and travel is seen by many as just that – a luxury they can no longer afford. Add on to this some unexpected external shocks and it’s unsurprising to see a company such as Thomas Cook, the second largest holiday business in the world, in talks with banks. It provides some 19 million holidays per year, but has seen a relatively rapid deterioration in its finances.

Its debts total in September 2011 was some £900 million and the value of the company has declined significantly in recent times. However, the most notable decline has been since it emerged that Thomas Cook was in talks with its banks in preparation for tougher times to come. It is hoping to receive £100 million from a range of banks including HSBC and Lloyds, but on this news Thomas Cook share prices fell by some 75%. However, Thomas Cook has said that the company is simply requesting money as a cushion and that it is not in a desperate financial situation. As the Acting Chief Executive, Sam Weihagen said, ‘I think investors should have confidence in Thomas Cook’.

Many factors have contributed towards Thomas Cook’s current situation – volcanic ash clouds, political unrest and unkind weather, but also some internal strategic decisions, such as their continued focus on package holidays, despite the fact that data suggests 2 in 3 people that go to Spain (a popular package destination) are actually not on a typical package holiday. The key thing with travel is that it is very much based on confidence (as we have also seen with the banking sector). If confidence in a company declines, people stop booking holidays with them and so further financial issues are created. This issue is even more significant when a well known brand name, such as Thomas Cook is the company in trouble. Nothing else makes such great headlines as a well known brand in trouble. So, should holiday makers be concerned? The following articles consider the situation that Thomas Cook faces.

Questions

  1. Explain the reason why share prices have fallen for Thomas Cook. Use a diagram showing the demand and supply of shares to support your explanation.
  2. Distinguish between the internal and external factors that have contributed to Thomas Cook’s current position.
  3. Under which aspect of PEST and STEEPLE analysis would you place the above influences?
  4. In the Telegraph article, an industry source says: ‘In a business like this you need a very conservative capital structure because you don’t know what’s going to come and bite you.’ What is meant by ‘a very conservative capital structure’?
  5. What action can Thomas Cook take to try to improve its current financial position? Think about both costs and revenues.
  6. What type of good would you class a holiday as? Based on this, what sort of figure would you place on the income elasticity of demand for holidays?
  7. How likely do you think it is that other travel companies are also experiencing similar financial issues to Thomas Cook?

The price of petrol at the pumps has risen substantially over the past few years. In the UK, according to the AA, the average price between January and June 2011 was 133.13p. In the same period in 2010 it was 116.68p; and in the same period in 2008 it was 109.00p.

Over the first six months of 2011, the amount of petrol sold fell by 5.2 per cent. This was on top of the decline in consumption over the previous four years. Between 2006 and 2010 consumption of petrol fell by 17.4%. The consumption of petrol and diesel are given in the following table.

UK consumption of petrol and diesel (tonnes millions)

Questions

  1. What factors have caused a fall in consumption of petrol?
  2. If you choose to spend a set amount on petrol, what is your price elasticity of demand?
  3. What determines the price elasticity of demand for petrol?
  4. Why has the consumption of diesel fallen less than that of petrol?
  5. Under what circumstances would an increase in tax on road fuel of 3p per litre (as planned for January 2012), result in a decrease in tax revenue? Why would the price elasticity of demand for road fuel have to be significantly greater than 1 (ignoring the minus sign) and not merely above 1 for this to be the case?
  6. Why is it likely that people’s price elasticity of demand for road fuel will become less elastic the more they have cut back on consumption?
  7. Why is the demand for petrol likely to be more elastic with respect to (a) price, and (b) income over the longer term?
  8. To what extent is the demand for road fuel a ‘derived demand’?
  9. To what extent is the fall in the consumption of petrol a reflection of a movement along the demand curve for petrol or a shift in the demand curve? Explain.

Anyone investing in commodities over the past few weeks will have been in for a bumpy ride. During the first part of 2011, commodity prices have soared (see A perfect storm brewing?). This has fuelled inflation and has caused the Bank of England to revise upwards its forecast for inflation (see Busy doing nothing see also Prospects for Inflation).

But then in the first week of May, commodity prices plumetted. On the 5 May, oil prices fell by 7.9% – their largest daily amount since January 2009. Between 28 April and 6 May silver prices fell from $48.35 per ounce to just over $33.60 per ounce – a fall of over 30%. And it was the same with many other commodities – metals, minerals, agricultural raw materials and foodstuffs.

Many financial institutions, companies and individuals speculate in commodities, hoping to make money buy buying at a low price and selling at a high price. When successful, speculators can make large percentage gains in a short period of time. But they can also lose by getting their predictions wrong. In uncertain times, speculation can be destabilising, exaggerating price rises and falls as speculators ‘jump on the bandwagon’, seeing price changes as signifying a trend. In more stable times, speculation can even out price changes as speculators buy when prices are temporarily low and sell when they are temporarily high.

Times are uncertain at present. Confidence fluctuates over the strength of the world recovery. On days of good economic news, demand for commodities rises as people believe that a growing world economy will drive up the demand for commodities and hence their prices. On days of bad economic news, the price of commodities can fall. The point is that when undertainty is great, commodity prices can fluctuates wildly.

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?”
