The UK energy industry (electricity and gas) is an oligopoly. There are six large suppliers: the ‘Big Six’. These are British Gas (Centrica, UK), EDF Energy (EDF, France), E.ON UK (E.ON, Germany), npower (RWE, Germany), Scottish Power (Iberdrola, Spain) and SSE (SSE Group, UK). The Big Six supply around 73% of the total UK market and around 90% of the domestic market.
Energy suppliers buy wholesale gas and electricity and sell it to customers. The industry has a considerable degree of vertical integration, with the energy suppliers also being involved in both generation and local distribution (long-distance distribution through the familiar pylons is by National Grid). There is also considerable horizontal integration, with energy suppliers supplying both electricity and gas and offering ‘dual-fuel’ deals, whereby customers get a discount by buying both fuels from the same supplier.
Smaller suppliers have complained about substantial barriers to entry in the industry. In particular, they normally have to buy wholesale from one of the Big Six. Lack of transparency concerning their costs and internal transfer prices by the Big Six has led to suspicions that they are charging more to independent suppliers than to themselves.
Under new regulations announced by Ofgem, the industry regulator, the Big Six will have to post the prices at which they will trade wholesale power two years in advance and must trade fairly with independent suppliers or face financial penalties. In addition, ‘a range of measures will make the annual statements of the large companies more robust, useful and accessible.’ According to the Ofgem Press Release:
From 31 March new rules come into force meaning the six largest suppliers and the largest independent generators will have to trade fairly with independent suppliers in the wholesale market, or face financial penalties. The six largest suppliers will also have to publish the price at which they will trade wholesale power up to two years in advance. These prices must be published daily in two one-hour windows, giving independent suppliers and generators the opportunity and products they need to trade and compete effectively.
But will these measures be enough to break down the barriers to entry in the industry and make the market genuinely competitive? The following articles look at the issue.

Microsoft’s Office suite is the market leader in the multi-billion dollar office software market. Although an oligopoly, thanks to strong network economies Microsoft has a virtual monopoly in many parts of the market. Network economies occur when it saves money and/or time for people to use the same product (software, in this case), especially within an organisation, such as a company or a government.
Despite the rise of open-source software, such as Apache’s OpenOffice and Google Docs, Microsoft’s Office products, such as Word, Excel and PowerPoint, still dominate the market. But are things about to change?
The UK government has announced that it will seek to abandon reliance on Microsoft Office in the public sector. Provided there are common standards within and across departments, it will encourage departments to use a range of software products, using free or low-cost alternatives to Microsoft products where possible. This should save hundreds of millions of pounds.
Will other governments around the world and other organisations follow suit? There is a lot of money to be saved on software costs. But will switching to alternatives impose costs of its own and will these outweigh the costs saved?

UK Supermarkets: a prime example of an oligopoly. This industry is highly competitive and over the past decade, but particularly since the onset of the credit crunch, price wars have been a constant feature of this market. You could barely watch a full programme on commercial TV without seeing one of the big supermarkets advertising that their prices were lower than everyone else’s! So, despite oligopoly being towards the ‘least competitive’ end of the market structure spectrum, this is an example of just how competitive the market can actually be.
With household incomes being squeezed, in particular by another oligopolistic industry (energy) and with the ‘middle market’ being pinched by higher-end retailers and budget retailers, the supermarket sector is facing uncertain times. Asda’s sales growth has continued to slow and in response, the giant supermarket chain will be launching a £1 billion price-cutting campaign. Tesco is the market leader, but Sainsbury’s and Asda have been battling over the second spot. One of Asda’s selling points is its low prices. Perhaps not as low as Aldi and Lidl, but this new pricing strategy will aim to bring its prices further below Tesco, Sainsbury’s and Morrisons and
close the gap with the two big discount supermarkets. As Andy Clarke, Asda’s Chief Executive, said:
We regard ourselves as the UK’s leading value retailer and it is against this backdrop that I have today set out our strategic priorities which will improve, extend and expand the business over the next five years.
So, what will be the impact of lower prices? It appears as though Asda is marketing itself towards the budget end of the pricing spectrum, perhaps aiming to become fiercer competitors with Aldi and Lidl and let Tesco and Sainsbury’s do battle with the higher-end retailers, such as Waitrose and Marks and Spencer. Lower prices should cause a substitution effects towards Asda’s products, as many of them will have relatively price elastic demand. If the other supermarkets don’t respond, this should lead to sales growth. However, the key to an oligopoly is interdependence: the actions of one firm will affect all other firms in the market. The implications then, are that Tesco may react to this pricing strategy by engaging in its own price cuts, especially as the Christmas period approaches. The characteristic of interdependence was evident in the aftermath of Asda’s announcement when shares in Tesco and Morrisons both fell, showing how the markets were responding.
Of course, there are many other factors that affect a consumer’s decision as to whether to shop at Asda, Tesco or any other big supermarket. In the area where I live, we have a Tesco and a Morrisons (a few years ago, we had neither!). I don’t shop at Asda, as the nearest branch is over 30 miles away – even if prices were significantly lower, it would be more expensive to get there and back and a lot less convenient. For others, it may be loyalty and not just of the ‘I’ve shopped there all my life’ kind! For some, clubcard vouchers from Tesco may be preferred to Asda’s offerings and thus tiny price differences between the supermarkets may have little effect on a consumer’s decision as to where to shop. Many products at supermarkets are relatively cheap and thus as the proportion of our income that we spend on these goods is pretty low, any change in price doesn’t cause much of an effect on our demand.
It’s not just a pricing strategy where money is being invested by Asda. More investment will be going into their online services and more stores will be created, kin particular in London and the South East where their presence is low, but demand appears to be high. Improving ‘product quality, style and design’ will also be on the agenda, all with the aim of boosting sales growth and securing its position as the second largest retailer in the sector, perhaps with a long term aim of one day overtaking Tesco. The following articles consider the supermarket battleground.

As Elizabeth noted in Fuelling the Political Playing Field, there has been much debate recently about energy prices in the UK. Four of the ‘Big Six’ energy companies have now announced price rises. They average 9.1% – way above the rate of consumer price inflation and even further above the average rate of wage increases. What is more, they are considerably above the rate of increase in wholesale energy prices, which, according to Ofgem, have risen by just 1.7% in the past year.
The bosses of the energy companies have appeared before the House of Commons Energy and Climate Change Select Committee to answer for their large price increases. The energy companies claim that the increases are necessary to cover not only rising wholesale prices, but also green levies by the government and ‘network charges’ for investments in infrastructure. 
However, it is hard to see how, even taking into account all three of these possible sources of cost increases, the scale of price increases can be justified.
Another possible explanation for the price hikes is that they are partly the result of a system of transfer pricing (see). The energy industry is vertically integrated. Energy companies are not only retailers to customers, but also generators of electricity and wholesale shippers of gas. It is possible that, by the producing/shipping arms of these companies charging higher prices to their retailing arms, the retailers’ costs do indeed go up more than the wholesale market cost. The result, however, is higher profits for the producing arms of these businesses. In other words, a higher transfer price allows profits to be diverted from each company’s retailing arm to its producing arm.
This is an argument for making the wholesale market more competitive and for stopping the by-passing of this market by producing arms of companies selling directly to their retailing arms. What the companies are being accused of is an abuse of market power and possibly of colluding with each other, at least tacitly, to support the continuation of such a practice.
So is the answer a price freeze, as proposed by the Labour Party? Is it an investigation of the energy market by the Competition Commission? Or is it, at least as a first step, much more openness by the energy companies and transparency about their pricing practices? Or is it to encourage consumers to switch between energy companies, including the smaller ones, which at present account for less than 5% of energy supply? The videos, podcasts and articles consider these issues.

Questions
- Why may the costs of energy paid by the energy retailers to energy producers/shippers have risen more than the wholesale price?
- Explain what is meant by transfer pricing. How could transfer pricing be used to divert profits between the different divisions of a business?
- How can transfer pricing be designed by multinational companies to help them minimise their tax bills?
- Why is policing transfer pricing arrangements notoriously difficult?
- What evidence is there to show that switching between retailers by customers can help to drive retail energy prices down?
- How did the old electricity pool system differ from the current wholesale system?
- Should electricity companies be forced to pool the electricity they generate and not sell it to themselves through bilateral deals?
- Comment on the following: “The current electricity trading arrangements ‘create the very special incentive for the oligopolists. …The best of all possible worlds is where nobody invests. As supply and demand close up, the price spikes upwards, and supernormal profits result.'”
‘Farm-gate’ milk prices (the price paid to farmers) have been rising in the UK. In July they reached a record high of 31.4p per litre (ppl). This was 5.1ppl higher than in July 2012. There were further price rises this month (October). Sainsbury’s increased the price it pays farmers by nearly 2ppl to 34.15ppl and Arla Foods by 1.5ppl to 33.13ppl. Muller Wiseman is set to raise the price it pays to 32.5p per litre.
And yet many farmers are struggling to make a profit from milk production, claiming that their costs have risen faster than the prices they receive. Feed costs, for example, have risen by 2.12ppl. On average, farmers would need over 38p per litre just to cover their average variable costs. What is more, exceptional weather has reduced yields per cow by some 7%.
Meanwhile, in the USA, supply has risen by some 1.3% compared with a year ago. But despite this, the prices of dairy products are rising, thanks to strong demand. Cheese and butter prices, in particular, are rising rapidly, partly because of high demand from overseas. Demand for imported dairy products is particularly high in China, where supply has fallen by some 6% in the past couple of months.
The problem for dairy farmers in the UK is partly one of the power balance in the industry. Farmers have little or no market power. Supermarkets, however, have considerable market power. As large oligopsonistic buyers, they can put downward pressure on the prices paid to their suppliers. These are mainly large processing firms, such as Robert Wiseman Dairies, Arla Foods and Dairy Crest. They, in turn, can use their market power to keep down the price they pay to farmers.
