From early January to late February 2013, the average pump price of petrol in the UK rose by over 6p per litre – a rise of 4.7% in just seven weeks. There have also been substantial rises in the price of diesel.
The higher prices reflect a rise in the dollar wholesale price of oil and a depreciation in the pound. From 2 January to 21 February the pound fell from $1.63 to $1.53 – a depreciation of 6.1% (see). Crude oil prices (in dollars) rose by just under 7% over this period. With oil imports priced in dollars, a weaker pound pushes up the price of oil in the UK. The price has then been pushed up even higher by speculation, fuelled by the belief that prices have further to rise.
The higher price of road fuel, plus the general squeeze on living standards from the recession, with prices rising faster than wages, has caused a reduction in the consumption of road fuel. Petrol sales have fallen to their lowest level for 23 years. Sales in January 2013 were 99m litres down on the previous month’s sales of 1564m litres (a fall of 6.3%).
Not surprisingly motorists’ groups have called for a reduction in fuel taxes to ease the burden on motorists. They also argue that this will help to drive recovery in the economy by leaving people with more money in their pockets.

Equally not surprisingly, those concerned about the environment have welcomed the reduction in traffic, as have some motorists who like the quieter roads, allowing journey times to be cut, with resulting reductions in fuel consumption per mile.
The following videos and articles discuss the causes of the most recent fuel price rises and also examine the responsiveness of demand to these higher prices and to the reductions in real incomes.

It’s a relatively common dish to see on a menu at a restaurant: mackerel. This particular fish has been promoted as a healthy and sustainable dish, but now its sustainability is coming into question and the Marine Conservation Society has taken it off its ‘fish to eat’ list. My brother Hugh is a marine biologist and often comments on which fish we should be avoiding due to sustainability issues (especially given how much I like fish!) So, how is this an economics issue?
There a couple of key things to pick out here. Firstly, with the conservationists’ warning of this issue of unsustainability, they have been asking consumers to reduce the amount of mackerel they buy. This will naturally have an impact on fisherman. If consumers do listen to the conservationists and hence reduce their demand for mackerel, we could see a fall in the price of this fish and a reduction in the fishermen’s turnover. It could be that we see a switch in consumption to other more sustainable fish, especially if we see some form of intervention.
Another area concerning economics is the idea of over-fishing. For years, there have been disputes over who has the rights to these fish stocks. In the past, the Faroe Isles and Iceland have increased their quotas significantly, as mackerel appear to have migrated to their shores, contributing to this question of sustainability. Iceland and the Faroe Isles have ‘unilaterally agreed their quotas … as they are not governed by the common fisheries policy’.
The question is: when fisherman catch one additional mackerel, what are they considering? Do they think about the private benefit to them (or their company) or do they consider the external cost imposed on others? Whenever one fish is taken from the sea, there is one less fish available for other fishermen.
This leads to over-consumption of fish and contributes towards the well-documented depletion of fish stocks and ‘The Tragedy of the Commons’, if account is not taken of the external cost imposed on other fishermen.
The total catch is now far in excess of what has been scientifically recommended and previously agreed upon by all participating countries. Negotiations to introduce new catch allowances have so far failed to reach agreement.
There are hopes that an international policy on quotas can be agreed to ensure mackerel levels return to or remain at a sustainable level. However, at present no progress has been made. Until some form of an agreement is reached, fishermen around Iceland and the Faroe Isles will continue to battle against the conservationists. The following articles consider this fishy topic.

Questions
- Why are quotas set by the EU for fishing? Who do they apply to?
- Why is there an externality from fishing?
- What is the Tragedy of the Commons? Using a diagram with average and marginal revenue product and average and marginal cost illustrate the market equilibrium and the social optimum. Why are they different?
- Following on from question 3, what does this suggest about the role of governments?
- If the conservationists’ request regarding buying less mackerel is successful, what impact might this have on fishermen and fisheries?
- If consumers do switch to buying other fish, what would happen to the equilibrium in the mackerel market and in the market for other fish? Think about this question in terms of general equilibrium analysis.
As resources become scarce, the price mechanism works to push up the price (see, for example, Box 9.11 in Economics 8th ed). If you look at the price of petrol over the past few decades, there has been a general upward trend – part of this is due to growth in demand, but part is due to oil being a scarce resource. Many millions have been spent on trying to find alternative fuels and perhaps things are now looking up!
Air Fuel Synthesis, a small British company, has allegedly managed to make ‘petrol from air’. Following this, the company has unsurprisingly received finance and investment offers from across the world. However, the entrepreneur Professor Marmont has said that he does not want any company from the oil industry to get a stake in this firm. This doesn’t mean that investment is not needed or on the cards, as in order to increase production of petrol from thin air financing is needed. Professors Marmont said:
We’ve had calls offering us money from all over the world. We’ve never had that before. We’ve made the first petrol with our demonstration plant but the next stage is to build a bigger plant capable of producing 1 tonne of petrol a day, which means we need between £5m and £6m
Whilst the process appears to be a reality, Air Fuel Synthesis is a long way from being able to produce en masse. However, it does offer an exciting prospect for the future of petrol and renewable energy resources in the UK. At the moment oil companies appear to be uninterested, but if this breakthrough receives the financing it needs and progress continues to be made, it will be interesting to see how the big oil companies respond. The following articles consider this break-through.

- As raw materials become scarce, prices of the goods that use them to work or require them to be produced will be affected. Explain this interdependence between markets.
- Why is investment from an oil company such a concern for Professor Marmont?
- Why is there unlikely to be any impact in the short run from this new breakthrough?
- If such a technology could be put into practice, what effect might this have on the price of petrol?
- How might oil companies react to the growth in this technology?
The energy sector has a history of criticism with regards to prices and practices. In the past, Ofgem have tried to make the sector more competitive, by ensuring that price comparisons are easier. At the beginning of this year, many of the big six providers announced price cuts, but within the next few weeks, we will see the reverse occurring, as energy prices begin to rise.
British Gas has announced price rises of 6% from 16th November that will affect over 8 million customers by adding approximately £80 per year to the annual dual fuel bill. Npower will also put its prices up 10 days later (8.8% for gas and 9.1% for electricity), creating higher bills for 3 million people.
In January of this year, when we saw energy prices fall, it was not solely due to Ofgem’s findings. We had a relatively mild winter, which reduced the demand for energy and this fed into lower prices. As the winter now approaches once more, demand for energy will begin to increase, feeding into prices that are now higher.
Furthermore, the energy companies have said that a range of external factors are also adding to their costs and putting increasing pressure on them to increase their charges. Npower’s Chief Commercial Officer said:
“There is never a good time to increase energy bills, particularly when so many people are working hard to make ends meet…But the costs of new statutory schemes, increases in distribution charges and the price of gas for the coming winter are all being driven up by external factors, for example government policy”
Significant investment is needed in the energy sector. Energy companies are required to set aside money for maintaining and improving the national grid and investing in renewable energy, such as wind and solar power. In order for the energy companies to fund these investments, more money must be raised and the logical method is to put up prices. However, critics are simply blaming ‘these very big lazy companies’ who are passing ‘above-inflation price rises’ onto already squeezed households.
Part of this is undoubtedly to do with the market structure of this sector. A typical oligopoly creates a market which, under certain circumstances, can be highly competitive, but because of barriers to entry that prevent new firms from entering the market may charge higher prices and be inefficient. Indeed, Ofgem has plans to reduce the power of the main energy providers by forcing them to auction off some of the electricity they generate. The aim of this is to free up the market and make it more competitive.
While only three providers have announced price rises, it is inevitable that the other three will follow. The relative increases will create incentives for consumers to switch providers, but crucial to this is an ability to understand the different tariffs on offer and lack of clarity on this has been a big criticism previously levelled at the energy sector. Indeed, half of UK customers have never switched energy providers. Perhaps this is the time to think about it, firstly as a means of saving money and secondly as a means of putting the energy companies in competition with each other. The following articles consider this market.

Virgin’s franchise to run the West Coast Main Line from London to Birmingham, Manchester, Liverpool, Glasgow and Edinburgh was due to expire in December. The Department of Transport thus invited tenders to run a new 13-year franchise, worth around £5 billion, and on 15 August announced that the franchise had been awarded to FirstGroup. It had bid substantially more than Virgin.
Virgin immediately challenged the decision, arguing that FirstGroup’s figures were flawed. According to the second BBC article below:
It argued that FirstGroup’s revenue projections were wildly optimistic – that passenger growth of 6% a year was unlikely given that Virgin had seen growth of 5% a year from a much lower base. This level of passenger growth would have seen FirstGroup’s revenue from the franchise grow by more than 10% a year, which was simply unrealistic, Virgin argued.
And it is not alone. “Everybody in the industry thought that this bid was not sustainable and that the risks had not been taken into account by the Department for Transport,” says rail industry expert Christian Wolmar.
If revenue targets are not met, the franchisee doesn’t have the money to pay the government the promised fee for the contract, which in FirstGroup’s case was back-loaded towards the end of the 13-year term.
After making its decision, the Transport Secretary at the time, Justine Greening, said that the process of assessing the bid was robust and fair and conducted with due diligence. Sir Richard Branson of Virgin strongly and publicly disagreed and Virgin decided to take the Department of Transport to court. The court case was scheduled to begin on 4 October.
However, in preparing its case to put to the court, the Department of Transport uncovered significant errors in the evaluation of the bids. These errors involved the overestimation of passenger numbers, the undervaluation of risk and a failure to take inflation into account. The errors stemmed from inputting the data incorrectly.
The errors were so serious that the new Transport Secretary, Patrick McLoughlin, on the day before the court case was due to begin, announced that he was scrapping the contract to FirstGroup and would invite new bids. All four of the original bidders would have their costs refunded, amounting to some £40 million.
The minister also announced that he was setting up two reviews. One would seek to establish just what went wrong in the assessment of the West Coat Main Line bids and what lessons could be learned. This is due to report at the end of October. The other review would examine the wider rail franchise programme and how bids are appraised. In the meantime, three other franchise competitions had been ‘paused’ pending the results of this second review, due to report in December.
The articles look at the problems of assessing bids and properly taking into account risks associated with both revenue and cost projections. Not surprisingly, they also look at the politics of this amazing and unprecedented U-turn
