When crude oil prices go up, the prices of petrol and diesel go up pretty well straight away and by the full amount, or more, of the crude price rise. When crude prices go down, however, road fuel prices are often slow to fall; and when they do, the fall is less than the full fall in crude prices.

In response to complaints of motorists and haulage companies, the Office of Fair Trading has announced that it will investigate the link between crude prices and prices at the pump. It will report in January 2013.
The review will consider questions of competition and market power. In particular, it will look at the power of the oil companies in determining the wholesale price of road fuel.
It will also examine the retail fuel sector and whether supermarkets are driving out independent retailers. The claim of many independent petrol stations is that supermarkets are selling below cost as a lost leader to encourage people to shop in their stores. They also claim that supermarkets use their buying power to obtain fuel more cheaply.
What is more, most of the petrol stations that are not part of supermarkets are owned by the oil companies. Again, independents claim that oil companies supply fuel more cheaply to their own stations than to independents.
As a result of what many independents see as unfair competition, many are driven out of business. Today there some 9000 petrol stations in the UK; 20 years ago there were twice as many.
The following articles look at the remit of the OFT investigation and at the competition issues in the road fuel market.

- What is meant by the terms ‘monosony’ and ‘oligopsony’? Which companies in the road fuel market have significant monopsony/oligopsony power?
- What determines the price elasticity of demand for road fuel in (a) the short run; (b) the long run? What implications does this have for the value of the short-run and long-run price elasticities?
- Where is the abuse of market power likely to occour in the road fuel market?
- To what extent is it in the consumers’ interests for supermarkets to sell road fuel below average cost?
- Examine the data for pump prices and crude oil prices and establish whether there is any truth in the claim that pump prices adjust rapidly to a rise in crude prices and slowly to a fall in crude prices.
Rail companies will be permitted to raise average regulated rail fares next year by 6.2%. Not surprisingly, this has been met with dismay and anger by rail travellers, especially long-distance commuters, who could see their annual season tickets going up by several hundred pounds.
Some fares, such as advance tickets, are unregulated. Others, such as anytime, off-peak and season tickets, are regulated by the government. The formula for working out permitted price rises for regulated fares is RPI plus 3%, where RPI is the July annual inflation rate based on the retail price index.
The RPI figure was announced by the ONS on 14 August and was a surprisingly high 3.2% – up from 2.8% in June: see Table 21 in the ONS’s CPI And RPI Reference Tables, July 2012. (Click here for a PowerPoint of the chart on the left.) Hence average fares can rise by 3.2% + 3% = 6.2%.
Rail travellers are angry on three counts:
First, the RPI measure of inflation is generally around 0.5% higher than the CPI measure (which is used for working out public-sector pay increases and the uprating of pensions and benefits). The July figure for CPI inflation was 2.6%.
Second, the extra 3% added on top of RPI means that that rail fares are going up more rapidly than other prices, and incomes too. The reason given for this is to shift the burden of funding the railways from the taxpayer to the traveller.
Third, the formula applies to average fares. Rail companies can raise particular regulated fares by up to 5 percentage points more than the formula provided they raise other fares by less than the formula. Thus some fares are set to rise by 11.2% – including some of the most expensive season tickets.
The government justified the increases by arguing that the higher fares will allow more investment by the rail companies, which could result in lower costs in the future. Nevertheless, two thirds of the revenue from the above-inflation increases will go to the government and only one third to the rail companies.

Questions
- What are the arguments for and against the general principle of using an RPI+X formula for regulating rail fares?
- What are the arguments for and against allowing train operating companies to raise regulated rail fares by an average of RPI plus 3%, with 2 of the 3 percent above RPI inflation going to the government?
- In what ways are travellers likely to respond to the higher prices?
- Why are some travellers likely to have a much lower price elasticity of demand for rail travel than others? What determines this price elasticity of demand?
- What externalities exist in rail transport? How should this impact on the government’s rail pricing strategy?
- How is infrastructure development funded for (a) rail, (b) roads and (c) airports? Does this lead to an efficient allocation of transport investment?
- How does rail pricing in the UK compare with that in other European countries? Should other European countries follow the UK’s policy of above inflation fare increases to fund rail investment?
A campaign to introduce a tax on disposable plastic bags in England has been launched by various pressure groups, including The Campaign to Protect Rural England (CPRE), Keep Britain Tidy, the Marine Conservation Society and Surfers Against Sewage. Plastic bags, they maintain, litter streets and the countryside and pollute the seas, where they cause considerable damage to marine life.
They propose a tax of 5p per bag, which would be passed on to consumers. Such a levy has already been introduced in Wales in October 2011. As a result, plastic bag use in Wales has dropped dramatically (see also the full report from the Welsh Government). The Scottish Government and the Northern Ireland Assembly are also planning introducing similar charges.
Many other governments have introduced taxes, charges or bans on plastic bags and many more are considering introducing such measures. Ireland introduced a 15 euro cent charge on single-use plastic bags as far back as 2002 and saw a 94% reduction in plastic bag use (328 per person per year to 21). The charge was raised to 22 euro cents in 2007 after bag use rose to 30 per person.
Other countries have banned plastic bags altogether: some, such as Rwanda and Somalia have banned all plastic bags; others, such as China and South Africa have banned very thin bags; others, such as Italy, have banned non-biodegradable ones.
In the USA, various states or districts have introduced levies and in the EU, where more than four billion bags are thrown away each year, the European Commission will soon publish proposals for limiting the use of plastic bags.
So what are the arguments for limiting the use of plastic bags? Why is it not enough to leave things simply to the market? And if the use of plastic bags is to be reduced, what’s the most efficient way of doing so? Are there any problems with alternatives to plastic bags? The following articles and reports consider these questions?

The 2012 London Olympics opened on 27 July. This has been the result of years of planning and investment in infrastructure since London won the bid in 2005.
It is estimated that hosting the Games will have cost over £9bn. It is therefore interesting to consider the long-run impact on a host city years after the last medal has been won. We might expect host cities to achieve increased growth due to the benefits from the improved infrastructure and the impact of increased publicity and exposure on trade, capital and population.
This has recently been investigated in a paper published in the Economic Inquiry by Stephen Billings and James Holladay which looks at the impact hosting the Games has on GDP and trade (working paper available here). One difficulty with trying to identify the impact of hosting the Games, is that only certain cities will have a chance of being chosen as hosts and these may be cities that are more likely to experience future growth. If this is the case, it would appear that the future growth was due to hosting the Games when it would in fact have been likely to occur anyway. In order to control for this, the above paper compares the winners with losing finalists in the selection process for host cities. For example under this approach London would be compared with Singapore, Moscow, New York and Madrid. In addition, subsequent matching processes are also used to select appropriate cities for comparison.
They find that larger cities in wealthier countries are more likely to be chosen to host the Games. However, once comparisons with other appropriate cities are made, overall, they find that hosting the Games has no effect on a cities population, growth or trade. One explanation provided is that the intense competition to host the Games means the potential gains are competed away via escalated promises in order to increase a cities chances of being selected. In addition, they note that there may well still be considerable specific benefits from the investments made to host the Games.
It is also clear that there are both positive and negative externalities from hosting the Games that, whilst difficult to measure, ideally should be taken into account. On the negative side, these include the extra hassle anybody travelling to work in London during the Games will face. On the other hand, on the positive side, it is hoped that part of the long-run legacy of the Games will be increased interest and participation in sport which would result in substantial health benefits.

Questions
- Explain how intense competition to host the Games might result in benefits being competed away.
- Can you think of any other externalities resulting from the Olympic Games?
- Why are the impact of externalities difficult to measure?
- What other factors should be taken into account when assessing the costs and benefits of hosting the Games?
- Do you think the decision to bid to host the Games should be purely based on a cost-benefit analysis?
Barclays’ Chief Executive, Bob Diamond, has resigned following revelations that Barclays staff had been involved in rigging the LIBOR in the period 2005–9, including the financial crisis of 2007–9.
So what is the LIBOR; how is it set; what were the reasons for Barclays (and other banks, as will soon be revealed) attempting to manipulate the rate; and what were the consequences?
The LIBOR, or London interbank offered rate, is the average of what banks report that they would have to pay to borrow from one another in the inter-bank market. Separate LIBORs are calculated for 15 different lending periods: overnight, one week, one month, two months, three months, six months, etc. The rates are set daily as the average of submissions made to Thomson Reuters by some 15 to 20 banks (a poll overseen by the British Bankers’ Association). Thomson Reuters then publishes the LIBORs, along with all of the submissions from individual banks which are used to calculate it.
Many interest rates around the world are based on LIBORs, or their European counterpart, EURIBORs. They include bond rates, mortgage rates, overdraft rates, etc. Trillions of dollars worth of such assets are benchmarked to the LIBORs. Thus manipulating LIBORs by even 1 basis point (0.01%) can result in millions of dollars worth of gains (or losses) to banks.
The charge, made by the Financial Services Authority, is that Barclays staff deliberately under- or overstated the rate at which the bank would have to borrow. For example, when interbank loans were drying up in the autumn of 2008, Barclays staff were accused of deliberately understating the rate at which they would have to borrow in order to persuade markets that the bank was facing less difficulty than it really was and thereby boost confidence in the bank. In other words they were accused of trying to manipulate LIBORs down by lying.
As it was the LIBORs were rising well above bank rate. The spread for the one-month LIBOR was around 1 to 1.2% above Bank Rate. Today it is around 0.1 to 0.15% above Bank Rate. Without lying by staff in Barclays, RBS and probably other banks too, the spread in 2008 may have been quite a bit higher still.
The following articles look at the issue, its impact at the time and the aftermath today.

When crude oil prices go up, the prices of petrol and diesel go up pretty well straight away and by the full amount, or more, of the crude price rise. When crude prices go down, however, road fuel prices are often slow to fall; and when they do, the fall is less than the full fall in crude prices.
