In June 2014, the Gas and Electricity Markets Authority (which governs the energy regulator, Ofgem) referred Great Britain’s retail and wholesale gas and electricity markets to the Competition and Markets Authority (CMA). The market is dominated by the ‘big six‘ energy companies (British Gas, EDF, E.ON, npower, Scottish Power and SSE) and Ofgem suspected that this oligopoly was distorting competition and leading to higher prices.
The CMA presented its report on 10 March 2016. It confirmed its preliminary findings of July and December 2015 “that there are features of the markets for the supply of energy in Great Britain that result in an adverse effect on competition”. It concludes that “the average customer could save over £300 by switching to a cheaper deal” and that “customers could have been paying about £1.7 billion a year more than they would in a competitive market”.
It made various recommendations to address the problem. These include “requiring the largest suppliers to provide fuller information on their financial performance” and strengthening the role of Ofgem.
Also the CMA wants to encourage more people to switch to cheaper suppliers. At present, some 70% of the customers of the big six are on default standard variable tariffs, which are more expensive than other tariffs available. To address this problem, the CMA proposes the setting up of “an Ofgem-controlled database which will allow rival suppliers to contact domestic and microbusiness customers who have been stuck on their supplier’s default tariff for 3 years or more with better deals.”
Another area of concern for the CMA is the 4 million people (16% of customers) forced to have pre-payment meters. These tend to be customers with poor credit records, who also tend to be on low incomes. Such customers are paying more for their gas and electricity and yet have little opportunity to switch to cheaper alternatives. 
For these customers the CMA proposed imposing transitional price controls from no later than April 2017 until 2020. These would cut typical bills by some £80 to £90 per year. In the meantime, the CMA would seek to remove “restrictions on the ability of new suppliers to compete for prepayment customers and reduce barriers such as debt issues that make it difficult for such customers to switch”.
Despite trying to address the problem of lack of competition, consumer inertia and barriers to entry, the CMA has been criticised for not going further. It has also been criticised for the method it has chosen to help consumers switch to cheaper alternative suppliers and tariffs. The articles below look at these criticisms.

Questions
- Find out the market share of the ‘big six’ and whether this has changed over the past few years.
- What, if any, are the barriers to entry in the gas and electricity retail markets?
- Why are the big six able to charge customers some £300 per household more than would be the case if they were on the cheapest deal?
- What criticisms have been made of the CMA’s proposals?
- Discuss alternative proposals to those of the CMA for dealing with the problem of excessive prices of gas and electricity.
- Should Ofgem or another independent not-for-profit body be allowed to run its own price comparison and switching service? Would this be better than the CMA’s proposal for allowing competitors access to people’s energy usage after 3 years of being with the same company on its standard tariff and allowing them to contact these people?
Two surveys have been released looking at the quality of life in cities and the levels of happiness of their residents. The first is a three-yearly Eurobarometer survey by the European Commission focusing on 83 European cities/conurbations. This survey finds that, despite growing concerns about immigration, terrorism and stagnant real incomes, levels of satisfaction have remained stable since the 2012 survey. In all except six cities, at least 80% of respondents say that they are satisfied to live in their city. The highest scores (above 98%) are in the north of Europe.
The second is the 2016 Quality of Life Survey (an annual survey) by the consultancy firm, Mercer. This looks at cities worldwide, particularly from the perspective of employees of multinational companies being placed abroad. The survey found that the top ten cities by quality of life include seven in Europe, and that the five safest cities in the world are all in Europe.
So what is it that makes the quality of life so high in many European cities, especially those in Germany, Austria, Switzerland, the Netherlands and Scandinavia? Is it that income per head is higher in these cities? In other words, is the quality of life related to GDP?
The answer is only loosely related to GDP. What seems more important is people’s income relative to other people and whether their income relative to other people is rising.
But people regard the quality of life in cities as depending on other factors than simple relative income. One factor common across all cities is household composition. People are least happy if they live on their own.
Other factors include: a feeling of safety; how well integrated different ethic and social groups are felt to be; the quality of public transport; the cleanliness of the city; health care provision and social services; the quality of schools and other educational establishments; sports facilities; cultural facilities; parks and other public spaces; the quality of shops, restaurants and other retail outlets; 
the quality and price of housing; the ease of getting a job; trust in fellow citizens; environmental factors, such as air quality, noise, traffic congestion and cleanliness; good governance of the city. The top three issues are health services, unemployment and education and training.
Although cities with higher incomes per head can usually afford to provide better services, there is only a loose correlation between income per head and quality of life in cities. Many of the factors affecting quality of life are not provided by the market but are provided publicly or are part of social interaction outside the market.

- Identify a particular city with which you are relatively familiar and assume that you were responsible for allocating the city’s budget. What would you spend more money on, what less and what the same? Provide a justification for your allocation.
- Discuss the following passage from the Bloomberg article: “What is striking is that there appears to be a correlation between those who report high levels of satisfaction and those who view foreigners in their city as an advantage. Conversely, respondents who complained loudest about transportation, public services, safety and other issues tended to view the presence of foreigners far less favorably.”
Wikipedia is a free on-line encyclopedia which is compiled and maintained by some of the people who use it regularly. It has been estimated that on any given day 15% of all internet users visit the website. Anyone can write new articles or edit existing material. The encyclopedia has over 5 million entries. So how is it financed?
If you visit the Wikipedia website at the moment you will be greeted by the following message:
DEAR READERS, We’ll get right to it: This week we ask you to help Wikipedia. To protect our independence, we’ll never run ads. We’re sustained by donations averaging about £10. Only a tiny portion of our readers give. If everyone reading this right now gave £2, our fundraiser would be done within an hour. That’s right, the price of a cup of coffee is all we need. We’re non-profit with costs of a top website: servers, staff and programs. We believe everyone should have access to free knowledge, without restriction or limitation. If Wiki We believe everyone should have access to free knowledge, without restriction or limitation. If Wikipedia is useful to you, please take one minute to keep our work going another year. Thank you.pedia is useful to you, please take one minute to keep our work going another year. Thank you.
Wikipedia Foundation, the not-for-profit company that manages the Wikipedia website, has been running these donation drives for a number of years. The 2014/15 financial year was their most successful to date as 4 million donations were made by people from all over the world. 
A total of $75 million was raised compared with $15 million in 2009/10. Although the average contribution was $15.20 in 2014/15, some people contributed over $250,000!
Many of you studying economics might find these figures surprising as Wikipedia would appear to have some of the characteristics associated with public goods. On the one hand, the material is perfectly non-rival. If someone decides to read an entry on Wikipedia it does not prevent other users from being able to read the same article. The article does not get used up or depleted in the act of being read. On the other hand, however, it is possible to exclude non-payers from gaining access to the material. For example in June 2010, the Times and Sunday Times introduced a subscription service for access to on-line versions of the newspapers. The New York Times recently announced that it had one million digital subscribers. However given its non-rivalrous nature, material could be shared between payers and non-payers. Groups of people could even get together and share one subscription.
The statement provided by Wikipedia clearly expresses the importance it attaches to free access. Given that it is non-rivalrous in consumption and free of charge to all users, does economic theory predict that people will (i) make voluntary monetary donations (ii) contribute and edit the on-line entries?
If all users are driven by narrowly self-interested preferences and act in a rational manner, then they will not pay and no donations will be made. People will choose to free ride as they can read exactly the same material whether they have paid for it or not.
Given the results of the fund-raising drive are so at odds with this prediction, it suggests that a significant number of Wikipedia users have either altruistic preferences and/or respond to social norms.
If a rational self-interested person receives no monetary payment for writing or editing an entry would they ever contribute to the website? Given the effort involved it would seem highly unlikely. However the Wikipedia website claims that over 125,000 people contribute regularly. They are referred to as ‘Wikipedians’.
One possible explanation for this behaviour is that some individuals gain utility/pleasure from other people reading and finding their entries both useful and interesting. This utility might increase with the number of potential readers. Therefore keeping access free is a motivating factor for a number of contributors as it maximises the potential readership of their entries. However, the number of contributors fell by a one third between 2007 and 2014.
An interesting question is whether the quantity and quality of contributions would increase if Wikipedia implemented a subscription service which generated enough revenue to enable contributors to be paid but also significantly reduced the number of users.
An alternative way of generating revenue would be to allow advertisements on the website while keeping access free of charge. This option has been resisted so far.

Pubs are closing down in the UK at the rate of 29 per week. The total number has fallen from 67,000 in 1982 to approximately 52,000 this year. In response to this decline the government has recently announced some changes to the way the relationship between pub owners and their tenants are regulated.
The ownership of pubs in the UK changed dramatically after a report on the beer market was published by the Monopolies and Mergers Commission (MMC) in 1989. When this investigation took place over 75% of the beer in the UK was produced by the six largest brewing businesses (Bass, Allied Lyons, Grand Metropolitan, Whitbread, Scottish and Newcastle, Courage) which owned over half the pubs. The nature of the relationship between these breweries and the landlords of the pubs they owned caused the greatest concerns.
Some pubs are run as managed houses. In this type of business relationship the person who manages and runs the pub (the publican) is a direct employee of the brewery. However, in many instances this is not the case. Instead they are independent entrepreneurs who enter into a tenancy agreement with the owner of the pub. In other words they rent the pub from the brewery and have some freedom over the way it is run including the setting of prices.
These arrangements have proved to be very controversial because of one particular aspect of many of the tenancy agreements – the exclusive supply contract. Known as the ‘tied lease model’, ‘beer tie’ or ‘wet rent’, it significantly reduces the freedom of publicans to run the business, as they have to purchase almost all their beverages from the brewery that owns the pub.
The MMC report in 1989 concluded that a significant reason for the increasing real price of beer was the market power exerted by the brewers through the tied lease model. It recommended that the number of pubs owned and operated by the brewers should be substantially reduced. Known as the ‘Beer Orders’, the brewers responded by gradually selling off 14,000 pubs. They also eventually sold the breweries to international rivals and companies such as Whitbread and Bass moved into the retail, leisure and hotel sectors. Whitbread currently owns Costa, Brewers Fayre and Premier Inn hotels while Bass, renamed Intercontinental Hotels Groups, owns both Crown Plaza and Holiday Inn hotels.
The beer tie between the pubs and the big national breweries might have disappeared but the tied lease arrangement still exists. Instead of being tied to national brewers, many publicans are tied to either smaller regional breweries, such as Everards and Adnams, or another type of business – the pub company known as ‘pubcos’. Some of the larger pubcos include Enterprise Inns, Punch Taverns, Mitchells&Butlers and JD Weatherspoon. They negotiate deals with the breweries and then supply the beer to their pubs.
In 2014, The British Beer and Pub Association estimated that two-fifths of pubs in the UK were owned by pubcos, while another fifth were owned by regional breweries. In 2013, The Department for Business, Innovation and Skills estimated that 48 per cent of pubs in the UK had landlords who were tied to either a regional brewer or a pub company.
The ownership of pubs may have changed radically over the past 20 years but the tied lease system continues to be extremely controversial. The main argument against the system is that it leads to tied publicans having to pay significantly above free market prices for their beer. The pubcos accept this claim but maintain that, in return for being in a tied lease, the publican pays a lower rent and receives business support services.
Parliament passed the Small Business, Enterprise and Employment Act in March 2015 (see Part 4). This included provisions for the introduction of:
|
|
| • |
a statutory Pubs Code to govern the relationship between the businesses that own the pubs and their tenants; |
| • |
a new independent Adjudicator to enforce the code; |
| • |
a Market Rent Only (MRO) option. |
In October 2015 the government announced some proposals for how the MRO option could be implemented as part of its consultation process with the industry. These include giving the tied publican the right to ask for a rent assessment every five years or whenever the owner of the pub significantly changes the beer prices it charges the tenant. As part of this rent assessment the publican can take the option to switch to an MRO contract. This gives them the freedom to purchase beer from any supplier rather than being tied to those supplied by the owner of the pub.
Enterprise Inns, the largest pubco, operates nearly all of its pubs on the tied lease model. In response to the changes proposed by the Government, the company has announced plans significantly to increase the number of its directly managed pubs from just 16 to 800.
Could the tied lease system finally be about to end?

After two weeks of negotiations between the 195 countries attending the COP21 climate change conference in Paris, a deal has been reached on tackling climate change. Although the deal still has to be ratified by countries, this is a major step forward in limiting global warming. Before it can formally come into force, it must have been ratified by at least 55 countries, accounting for at least 55% of global greenhouse gas emissions.
The deal goes much further than previous agreements and includes the following:
- A limit on the increase in global temperatures to ‘well below’ 2°C above pre-industrial levels and efforts pursued to limit it to 1.5°C.
- A recognition that the pledges already made ahead of the conference by 186 countries and incorporated into the agreement are insufficient and will only limit global temperature rise to 2.7°C at best.
- Countries to update their emissions reductions commitments every five years – the first being in 2020. Such revised commitments should then be legally binding.
- A global ‘stocktake’ in 2023, and every five years thereafter, to monitor countries’ progress in meeting their commitments and to encourage them to make deeper cuts in emissions to reach the 1.5°C goal. This requires a process of measurement and verification of countries’ emissions.
- To reach a peak in greenhouse gas emissions as soon as possible and then to begin reducing them and to achieve a balance between sources and sinks of greenhouse gases (i.e. zero net emissions) in the second half of this century.
- Developed countries to provide the poorest developing countries with $100bn per year by 2020 to help them reduce emissions. This was agreed in Copenhagen, but will now be continued from 2020 to 2025, and by 2025 a new goal above $100bn per year will be agreed.
- The development of market mechanisms that would award tradable credits for green projects and emissions reductions.
- A recognition that the ‘loss and damage’ associated with climate-related disasters can be serious for many vulnerable developing countries (such as low-lying island states) and that this may require compensation. However, there is no legal liability on developed countries to provide such compensation.
Perhaps the major achievement at the conference was a universal recognition that the problem of global warming is serious and that action needs to be taken. Mutual self interest was the driving force in reaching the agreement, and although it is less binding on countries than many would have liked, it does mark a significant step forward in tackling climate change.
But why did the conference not go further? Why, if there was general agreement that global warming should be tackled and that global temperature rise should ideally be capped at 1.5°C, was there not a binding agreement on each country to apply this cap?
There are two reasons.
First, it is very difficult to predict the exact relationship, including its timing, between emissions and global temperature rise. Even if you could make limits to emissions binding, you could not make global temperature rise binding.
Second, even if there is general agreement about how much emissions should be reduced, there is no general agreement on the distribution of these reductions. Many countries want to do less themselves and others to do more. More specifically, poor countries want rich countries to do all the cutting while many continue to build more coal-fired power stations to provide the electricity to power economic development. The rich countries want the developing countries, especially the larger ones, such as China, India and Brazil to reduce their emissions, or at least the growth in their emissions.
Then there is the difference between what countries vaguely pledge at a global conference and what they actually do domestically. Many developed countries are keen to take advantage of currently cheap fossil fuels to power economic growth. They are also still investing in alternative sources of fossil fuels, such as through fracking.
As we said in the previous blog, game theory can shed some useful insights into the nature and outcome of climate negotiations. ‘The global optimum may be for a strong agreement, binding on all countries. The Nash equilibrium, however, may be a situation where countries push for their own interests at the expense of others, with the final agreement being much more minimalistic.’
‘Minimalistic’ may be too strong a description of the outcomes of the Paris conference. But they could have been stronger. Nevertheless, judged by the outcomes of previous climate conferences, the deal could still be described as ‘historic’.
