One example of an oligopoly was recently discussed on this blog –supermarkets. Here, is another classic example: the energy sector. It is dominated by six big firms, which hold the majority of the market in an industry with high barriers to entry; there is inter-dependence between the firms; and there are accusations of price fixing and collusion – all typical features of an oligopoly that may operate against consumers’ interests.
There have been numerous investigations into the actions of these energy providers, owing to their high prices, a lack of competition and significant profits. Developments in the industry have focused on reducing the barriers to entry created by the vertical integration of the incumbent firms in order to make it easier for new firms to enter, thus boosting competition.
However, the latest step is the biggest one, with the energy regulator, Ofgem, referring this industry to the Competition and Markets Authority (CMA). The investigation is likely to last 18 months and will ‘leave no stone unturned in establishing the truth behind energy prices’.
One of the key things that will be investigated is the accusation of profiteering and thus whether the big six should be broken up. This would inevitably lead to reductions in entry barriers and more opportunities for new firms to enter the market, thereby creating a much needed increase in competition. The Chief Executive of Ofgem, Dermot Nolan said:
Now is the right time to refer the energy market to the CMA for the benefit of consumers…There is near-unanimous support for a referral and the CMA investigation offers an important opportunity to clear the air. This will help rebuild consumer trust and confidence in the energy market as well as provide the certainty investors have called for.
Further comments were made about the energy sector and the future direction in terms of market reforms. This was another reason given for the referral to the CMA. Dermot Nolan added:
A CMA investigation should ensure there are no barriers to stop effective competition bearing down on prices and delivering the benefits of these changes to consumers.
The impact of this latest news will undoubtedly be felt by the big six, with share prices already taking a small hit, as investors start to look ahead to the potential outcome, despite any decision not being expected for a good 18 months.

Questions
- How well does the energy sector fit the structure of an oligopoly?
- What are the barriers to entry in the energy market? How can this referral to the CMA help to reduce them?
- Which factors determine the price of energy?
- The big six have been accused of profiteering. What is meant by this and why is it against the public interest?
- Why has it taken so long for such a referral to take place?
- In the BBC News article, the suggestion is that this investigation could lead to a ‘major structural change’. What is meant by this and why is it a possibility?
Last month the Swiss air freight company Kuehne + Nagel International AG was fined just over NZ$3m (around £1.5m) by the New Zealand Commerce Commission for their part in a price fixing cartel that ran for 5 years.
In 2002 the firms in the industry faced higher costs due to increased security measures imposed by the British government. They formed a cartel to agree to pass these increased costs on to their customers for air freight services from the UK to a number of countries, including New Zealand. The investigation by the New Zealand competition authority followed a leniency application by one of the participants in 2007. Five other participants had previously been fined, but Kuehne + Nagel decided to fight the case. The fine imposed on them brought the total fines to almost NZ$12m (around £6m).
A previous post on this site highlighted how golf played a prominent role in several previous cartels. However, this cartel seemed to have had a fixation on gardening and referred to the cartel as the gardening club. Other parties involved in the cartel were referred to as fellow gardeners and the agreed upon price as the price for asparagus! When a participant suspected a rival may have cheated on the cartel agreement email exchanges such as this one took place:
I hear… concerns about the price of produce from the garden of Velcro, which appears to be operating as a charitable cooperative for the benevolence of vegetable eaters rather than growers…
It is not known whether the Kuehne + Nagel employees involved in the cartel were placed on gardening leave during the investigation!

Questions
- Why is an increase in costs likely to trigger price fixing behaviour?
- Why might the members want to use code names to run a cartel’s activities?
- Why do competition authorities grant leniency to cartel members that inform them about price fixing behaviour?
Calls for an independent Scotland have focused on a variety of economic issues. These have included taxation, government spending, currency, fiscal policy and monetary policy. However, the BBC News article below looks at another factor which may be affected by a ‘yes’ vote – the price of stamps.
Having just returned from 10 days in the Highlands, I certainly agree with the BBC article that it would be an expensive business to deliver to the remotest parts of Scotland and would definitely require ‘trains, planes, ferries, Land Rovers and vans’ and, in an extreme case, a fishing boat.
So is the price we pay for postage to less rural areas of the UK used to subsidise the higher costs of delivery to the remotest parts of Scotland and, in particular, to the small islands off the Scottish coastline? What would a ‘yes’ vote mean for the cost of stamps in Scotland and in the remainder of the UK? The following articles consider this rather odd question.
Why postage should be cheaper in UK if Scots vote ‘Yes’ BBC News, Brian Milligan (19/4/14)
Tories warn over post service costs The Courier (6/4/14)
Questions
- What happened when the Royal Mail was privatised?
- What are the benefits and costs of privatisation?
- Using a cost and revenue diagram, explain how the different costs of delivery between urban parts of the UK and the remotest parts of Scotland should be reflected in different prices of postage.
- If the price of postage is the same for delivery everywhere in the UK, use your diagram to explain how this happens.
- What does your diagram suggest will happen to the price of postage stamps if a ‘subsidy’ is no longer available?
According to latest evidence from the Bank for International Settlements, in April 2013 some £3.2 trillion ($5.3 trillion) of foreign exchange was traded daily on global foreign exchange (forex) markets. About 40% of forex dealing goes through trading rooms in London. This market is highly profitable for the UK economy. But all is not well with the way people trade. There is a scandal about rate fixing.
Exchange rates on the forex market are freely determined by demand and supply and fluctuate second by second, 24 hours a day, except for weekends. Nevertheless, once a day rates are fixed for certain trades. At 4pm GMT a set of reference rates is set for corporate customers by banks and other traders. The rates are set at the free market average over the one minute from 16:00 to 16:01. The allegation is that banks have been colluding, through text messaging and chat rooms, to manipulate the market over that one minute.
Since the early summer of 2013, the Financial Conduct Authority (FCA) in the UK, along with counterparts in the USA, Switzerland, Hong Kong and elsewhere, has been looking into these allegations. Last week (4/3/14), the Bank of England suspended a member of its staff as part of its own investigation into potential rigging of the foreign exchange market. The allegation is not that the staff member(s) were involved in the rigging but that they might have known about it.
The Bank said that, “An oversight committee will lead further investigations into whether bank officials were involved in forex market manipulation or were aware of manipulation, or at least the potential for such manipulation.”
Meanwhile, the House of Commons Treasury Select Committee has been questioning Bank of England staff, including the governor, Mark Carney, about the scandal. Speaking to the Committee, Martin Wheatley, head of the FCA said that the investigation over rigging had been extended to 10 banks and that the allegations are every bit as bad as they have been with Libor.

Questions
- For what reasons would sterling appreciate against the dollar?
- Most of forex trading is for speculative purposes, rather than for financing trade or investment. Why is this and does it benefit international trade?
- If foreign exchange rates fluctuate, is it not a good thing that banks collude to agree the 4pm fixed rate? Explain.
- What was the Libor scandal? Why are some people arguing that the current forex scandal is worse?
- What can the FCA do to prevent collusion over exchange rates?
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.
