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?
People are beginning to get used to low oil prices and acting as if they are going to remain low. Oil is trading at only a little over $30 per barrel and Saudi Arabia is unwilling to backtrack on its policy of maintaining its level of production and not seeking to prevent oil prices from falling. Currently, there is still a position of over supply and hence in the short term the price could continue falling – perhaps to $20 per barrel.
But what of the future? What will happen in the medium term (6 to 12 months) and the longer term? Investment in new oil wells, both conventional and shale oil, have declined substantially. The position of over supply could rapidly come to an end. The Telegraph article below quotes the International Energy Agency’s executive director, Fatih Birol, as saying:
“Investment in oil exploration and production across the world has been cut to the bone, falling 24% last year and an estimated 17% this year. This is… far below the minimum levels needed to keep up with future demand. …
It is easy for consumers to be lulled into complacency by ample stocks and low prices today, but they should heed the writing on the wall: the historic investment cuts raise the odds of unpleasant oil security surprises in the not too distant future.”
And in the Overview of the IEA’s 2016 Medium-Term Oil Market Report, it is stated that
In today’s oil market there is hardly any spare production capacity other than in Saudi Arabia and Iran and significant investment is required just to maintain existing production before we move on to provide the new capacity needed to meet rising oil demand. The risk of a sharp oil price rise towards the later part of our forecast arising from insufficient investment is as potentially de-stabilising as the sharp oil price fall has proved to be.
The higher-cost conventional producers, such as Venezuela, Nigeria, Angola, Russia and off-shore producers, could take a long time to rebuild capacity as investment in conventional wells is costly, especially off-shore.
As far as shale oil producers is concerned – the prime target of Saudi Arabia’s policy of not cutting back supply – production could well bounce back after a relatively short time as wells are re-opened and investment in new wells is resumed.

But, price rises in the medium term could then be followed by lower prices again a year or two thereafter as oil from new investment comes on stream: or they could continue rising if investment is insufficient. It depends on the overall balance of demand and supply. The table shows the IEA’s forecast of production and consumption and the effect on oil stocks. From 2018, it is predicting that consumption will exceed production and that, therefore, stocks will fall – and at an accelerating rate.
But just what happens to the balance of production and consumption will also depend on expectations. If shale oil investors believe that an oil price bounce is temporary, they are likely to hold off investing. But this will, in turn, help to sustain a price bounce, which in turn, could help to encourage investment. So expectations of investors will depend on what other investors expect to happen – a very difficult outcome to predict. It’s a form of Keynesian beauty contest (see the blog post A stock market beauty contest of the machines) where what is important is what other people think will happen, which in turn depends on what they think other people will do, and so on.

Pork – a favourite food of many Brits, whether it’s as a key ingredient of a roast dinner or a full English Breakfast! But, British pig farmers may be in for a tricky ride and we might be seeing foreign pork on our plates in the months to come. This is because of the falling price of pork, which may be driving local farmers out of the market.
As we know, market prices are determined by the interaction of demand and supply and as market conditions change, this will affect the price at which pork sells at. This in turn will have an impact on the incomes of farmers and hence on farmers’ ability to survive in the market. According to forecasts from Defra, specialist pig farms are expected to see a fall in income by 46%, from £49,400 to £26,500 in 2016. A key driver of this, is the decline in the price of pork, which have fallen by an average of £10 per pig. This loss in income has led to pig farmers facing the largest declines of any type of farm, even beating the declines of dairy farmers, which have been well-documented.
If we think about the forces of demand and supply and how these have led to such declines in prices, we can turn to a few key things. Following the troubles in Russia and the Ukraine and Western sanctions being imposed on Russia, a retaliation of sorts was Russia banning European food imports. This therefore reduced demand for British pork. Adding to this decline in demand, there were further factors pushing down demand, following suggestions about the adverse impact that bacon and ham have on health. If pig farmers in the UK continue with the number of pigs they have and bearing in mind they would have invested in their pig farms before such bans and warnings were issued, then we see supply being maintained, demand falling and prices being pushed downwards.
Zoe Davies, Chief Executive of the National Pig Association said:
“This year is going to be horrendous for the British pig industry … Trading has been tough for at least 18 months now and we are starting to see people leave. We’re already seeing people calling in saying they’ve decided to give up. All we can hope is that more people leave European pig farms before ours do.”
We can also look to other factors that have been driving pig farmers out of business, including a strong pound, the glut of supply in Europe and productivity in the UK. Lily Hiscock, a commentator in this market said:
“It is estimated that the average pig producer is now in a loss-making position after 18 months of positive margins … The key factors behind the fall in markets are the exchange rate, UK productivity and retail demand … Indeed, pigmeat seems to be losing out to cheaper poultry meat in consumers’ shopping baskets … The recent fall in prices may stimulate additional demand, and a strengthening economy could help, but at present these are hopes rather than expectations.”
The future of British pig farms is hanging in the balance. If the economy grows, then demand may rise, offsetting the fall in demand being driven by other factors. We will also see how the exit of pig farmers affects prices, as each pig farmer drops out of the market, supply is being cut and prices rise. Though this is not good news for the farmers who go out of business, it may be an example of survival of the fittest. The following articles consider the market for pork.

Economics, but not as we know it. As the introduction to this programme on BBC radio 4 suggests, there has been criticism and concern about the way in which we think about economics. About, how it’s taught; the lessons we learn and whether we need to have a re-think. Tomas Sedlacek is a Czech economist and has a different way of thinking about this subject.
Humanomics is certainly a new way of thinking about economics and considering how it links and can be applied to a wide range of areas: the Bible; movies such as Fight Club and the Matrix. This 30 minute discussion between Evan Davies and Tomas Sedlacek provides some interesting insights and thoughts on some of the current challenges facing this subject and some novel insights into how we could change our thinking.

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’.
