A weekly expense for most families is filling up their car(s) with petrol, but this activity is becoming increasingly expensive and is putting added pressure on lower and middle income families in particular. For those families on lower incomes, a tank of petrol represents a much larger percentage of their income than it does for a higher income household. Assuming that petrol for a month costs you £70 and your monthly income is £500, as a percentage of your income, a tank of petrol costs you 14%. Whereas, if your income is £900, the percentage falls to 7.7% and with a monthly take-home pay of £2000, the cost of a month’s petrol as a percentage of your income is just 3.5%. This is a stark indication of why those on lower incomes feel the burden of higher petrol prices (and indeed, higher prices for any essential items) more than other families.
The price of petrol will today be debated by MPs, following an e-petition signed by more than 100,000 people and having the support of more than 100 MPs. When in power, the Labour government proposed automatic fuel-tax increases, but these were scrapped by the Coalition. However, in January, the government plans to increase fuel duty by 3p a litre and further increases in prices are expected in August in line with inflation. This could mean that the price of unleaded petrol rises to over 1.40p per litre.
And it’s not just households that are feeling the squeeze. The situation described in the first paragraph is just as relevant to firms. The smaller firms, with lower turnover and profits are feeling the squeeze of higher petrol prices more than their larger counterparts. Any businesses that have to transport goods, whether to customers or from wholesalers to retailers etc, are seeing their costs rise, as a tank of petrol is requiring more and more money. To maintain profit margins, firms must pass these cost increases on to their customers in the form of higher prices. Alternatively, they keep prices as they were and take a hit on profitability. If prices rise, they lose customers and if prices are maintained, profitability suffers, which for some companies, already struggling due to the recession, may not be an option.
Mr. Halfon, the Tory MP whose motion launched the e-petition said that fuel prices were causing ‘immense difficulties’ and the Shadow Treasury Minister Owen Smith has said:
‘With our economic recovery choked off well before the recent eurozone crisis, we need action.’
With inflation at 5.2% (I’m writing an hour or so before new inflation data is released on 15/11/11), higher prices for many goods is putting pressure on households. This is possibly contributing towards sluggish growth, as households have less and less disposable income to spend on other goods, after they have purchased their essential items, such as groceries and petrol. A criticism leveled at oil companies is that they quickly pass on price rises, as the world price of oil increases, but do not pass on cuts in oil prices. The issues raised in the debate and how George Osborne and David Cameron respond, together with inflation data for the coming months, may play a crucial role in determining just how much a tank of petrol will cost in the new year.

Questions
- As the price of petrol rises, why do people continue to buy it? What does it suggest about the elasticity of this product?
- Why do higher prices affect lower income families more than higher income families?
- What are the arguments (a) for and (b) against George Osborne’s planned 3p rise in petrol duty?
- Do you think that higher prices are contributing towards sluggish growth? Why?
- What type of tax is imposed on petrol? Is it equitable? Is it efficient?
- Why can the oil companies pass price rises on to petrol stations, but delay passing on any price reductions? Is there a need for better regulation and more pressure on oil companies to change their behaviour?
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 UK Supermarket industry is intensely competitive. It’s hard to slot it directly into a specific market structure, but it has many characteristics of an oligopoly – a market dominated by a few firms with intense competition, both price and non-price.
This competititve aspect of the market structure has become even more important as trading conditions become harsher. The latest development sees Sainsbury’s announcing its price promotion – it will match certain prices offered by Tesco and Asda in a bid to attract customers from its rivals.
The supermarket industry has a history of intense price wars and we can only expect them to increase. This is certainly in the interests of customers, as we face ever decreasing prices. It’s a market in which it certainly pays to shop around and compare prices. The following articles consider the latest developments in one of the most competitive markets out there.

- Are the price wars being carried out by Tesco, Sainsbury’s and Asda in the interests of consumers?
- What aspects of non-price competition have been undertaken by the big supermarket contenders? On what factors does the relative success of these pricing strategies depend?
- What might explain the growing presence of fast food companies in the top 100?
- How could the supermarkets use the concept of elasticity in determining the most effective pricing strategy?
- How has the economic climate affected the supermarket industry? Would you expect the impact to be smaller or larger than that in other sectors of the economy? Explain your answer.
Stock markets have been plummeting. The FTSE 100 index was 6055 on 7 July 2011; by 10 August, it was 17% lower at 5007. Since then it has risen as high as 5418, but by 13 September was down to 5092. Other stock markets have fared worse. The French index fell 30% between early July and September 13, and the German DAX index fell 32% over the same period.
These falls in share prices reflect demand and supply. Investors are worried about the future of the eurozone and the health of the European economy as Greek default looks more and more likely and as the debts of various other European countries, such as Portugal, Ireland and Spain, seem increasingly unsustainable in an environment of sluggish economic growth. They are also worried about high public-sector debt in the USA and the likelihood that global recovery will peter out.
The ‘bear’ market (falling share prices) reflects increased selling of shares and a lack of demand. Not only are investors worried about the global economy, they are also speculating that share prices will fall further, thereby compounding the falls (at least until the ‘bottom’ is reached).
But why have share prices fallen quite so much? And does it matter to the general public that this is happening? The following articles seek to answer these questions.

Friday 5 August 2011 saw the end of a very bad fortnight for stock markets around the world. In Japan the Nikkei 225 had fallen by 8.2%, in the USA the Dow Jones had fallen by 9.8%, in the UK the FTSE 100 was down 11.6% and in Germany the Dax was down 14.9%. In the first five days of August alone, £148 billion had been wiped off the value of the shares of the FTSE 100 companies and $2.5 trillion off the value of shares worldwide.
But why had this happened and what are likely to be the consequences?
The falls have been caused by the growing concerns of investors about the health of the global economy and the global financial system. There are worries that the European leaders at their summit on 21 July did not do enough to prevent the default of large countries such as Spain and Italy. There are concerns that the US political system, following the squabbling in Congress over raising the sovereign debt ceiling for the country, may not be up to dealing with the country’s huge debts. Indeed, the rating agency, Standard & Poor’s, downgraded the USA’s credit rating from AAA to AA+. This is the first time that the USA has not had top rating.
Then there are worries about the general slowing down of the world economy and how this will compound the problem of sovereign debt as it hits tax revenues and makes it harder to reduce social security payments. Underlying all this is the fear that the problem of indebtedness that contributed to the banking crisis of 2007/8 has not gone away; it has simply been transferred from banks to governments. As Robert Peston states in his article, linked to below:
The overall volume of indebtedness in the economy is therefore still with us – although it has been shuffled from financial sector to public sector.
And if you took the view four years ago that the quantum of debt in the system was unsustainably large, then you would argue that by propping up the banks, the day of reckoning was being postponed, not cancelled.
… just like the awakening in 2007 to the idea that many of the housing loans and associated financial products were worthless, so there is a growing fear that a number of financially overstretched governments, especially in the eurozone, will not be able to repay their debts in full.
Which brings us to the consequences. Key to the answer is confidence. If governments can reassure markets over the coming days and weeks that they have credible policies to support highly indebted countries in the short term and to sustain demand in the global economy (e.g. through further quantitative easing in the USA (QE3)); and if they can also reassure markets that they have tough and credible policies to reduce their debts over the longer term, then confidence may return. But it will not be an easy task to get the balance right between sustaining recovery in the short term and fiscal retrenchment over the long term. Meanwhile consumers are likely to become even more cautious about spending – hardly the recipe for recovery.
