The Supermarket Battleground

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.

An energy cartel?

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.'”

Milk prices: who gets the cream?

‘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.

Miliband’s freeze

For all households, energy is considered an essential item. As electricity and gas prices rise and fall, many of us don’t think twice about turning on the lights, cooking a meal or turning on the heating. We may complain about the cost and want prices brought down, but we still pay the bills. But, is there anything that can be done about high energy prices? And if there is, should anything be done?

The worlds of politics and economics are closely linked and Ed Miliband’s announcement of his party’s plans to impose a 20-month freeze on energy prices if elected in 2015 showed this relationship to be as strong as ever. The price freeze would certainly help average households reduce their cost of living by around £120 and estimates suggest businesses would save £1800 over this 20 month period. The energy companies have come in for a lot of criticism, in particular relating to their control of the industry. The sector is dominated by six big companies – your typical oligopoly, and this makes it very difficult for new firms to enter. Thus competition is restricted. But is a price freeze a good policy?

Part of the prices we pay go towards investment in cleaner and more environmentally friendly sources of energy. Critics suggest that any price freeze would deprive the energy sector of much needed investment, meaning our energy bills will be higher in the future. Furthermore, some argue this price freeze suggests that Labour is abandoning its environmental policy. Energy shortages have been a concern, especially with the cold weather the UK experienced a few years ago. This issue may reappear with price freezes. As Angela Knight, from Energy UK, suggests:

Freezing the bill may be superficially attractive, but it will also freeze the money to build and renew power stations, freeze the jobs and livelihoods of the 600,000-plus people dependent on the energy industry and make the prospect of energy shortages a reality, pushing up the prices for everyone.

There is a further concern and that is that large energy companies will be driven from the UK. This thought was echoed by many companies, in particular the British Gas owner Centrica, commenting that:

If prices were to be controlled against a background of rising costs it would simply not be economically viable for Centrica to continue to operate and far less to meet the sizeable investment challenge that the industry is facing…The impact of such a policy would be damaging for the country’s long-term prosperity and for our customers.

Share prices naturally fluctuate with global events and a political announcement such as this was inevitably going to cause an effect. But, perhaps the effect was not expected to be as big as the one we saw. Share prices for Centrica and SSE fell following the announcement – perhaps no great shock – but then they continued to fall. The market value tumbled by 5% and share prices kept falling. This has led to Ed Miliband being accused of ‘economic vandalism’ by a major shareholder of Centrica, which is hardly surprising, given the estimated cost of such a price freeze would be £4.5 billion.

The economic implications of such a move are significant. The announcement itself has caused massive changes in the FTSE and if such a move were to go ahead if Labour were elected in 2015, there would be serious consequences. While families would benefit, at least in the short term, there would inevitably be serious implications for businesses, the environmental policy of the government, especially relating to investment and the overall state of the economy.

Apple found guilty of coordinating the fixing of e-book prices

Apple was last week found guilty in the US for its role in the fixing of e-book prices. A subsequent hearing will now be held to determine the damages that Apple will be forced to pay. However, Apple vehemently denies the allegations and looks set to appeal the decision.

To understand what the US Department of Justice (the European Commission has also brought a case) is objecting to, we need to look back to how pricing in this rapidly growing market has evolved over time.

Until the end of 2009 e-books were sold under a wholesale pricing model. Here, publishers charge retailers a wholesale price per book and retailers are then free to charge final consumers whatever price they choose. This all changed in the US (there were also similar developments in Europe) during an eventful period of a few days in January 2010 when Apple unveiled its iPad for April release.

The publisher Macmillian proposed that Amazon switch to an agency pricing model under which the publisher sets the retail price. This is typically referred to by economists as Resale Price Maintenance (RPM). Interestingly, RPM has a long history in the book industry. In the UK for example, throughout most of the last century publishers set prices under the Net Book Agreement, until this broke down in the mid 1990s. In addition, in some countries, for example Germany, books continue to be sold under RPM.

Macmillan also threatened Amazon that if it preferred to keep wholesale pricing it would delay the supply of e-book releases to them. Amazon initially responded by refusing to stock Macmillan titles. However, soon after Amazon ceded to Macmillan’s proposal. Despite this, Amazon made clear its dissatisfaction to its customers:

We have expressed our strong disagreement and the seriousness of our disagreement by temporarily ceasing the sale of all Macmillan titles. We want you to know that ultimately, however, we will have to capitulate and accept Macmillan’s terms because Macmillan has a monopoly over their own titles, and we will want to offer them to you even at prices we believe are needlessly high for e-books.

It turned out that 5 of the 6 major publishers (including Macmillan) had already agreed the same agency terms to sell e-books for Apple devices. Like Macmillan, the other publishers all then also imposed agency pricing on Amazon. Furthermore, crucial to the contracts agreed with Apple was a so called ‘most-favoured customer’ clause which guaranteed that e-books would not be sold elsewhere at prices below those charged to Apple customers. Effectively, therefore, this clause made it necessary for the publishers to impose agency terms on Amazon. The Department of Justice objected to this and believed consumers would be harmed due to higher prices. All of the publishers involved eventually decided to settle the case, leaving Apple alone to fight the case in court.

In the decision Judge Cote concluded that:

the publisher defendants conspired with each other to eliminate retail price competition in order to raise e-book prices, and that Apple played a central role in facilitating and executing that conspiracy. Without Apple’s orchestration of this conspiracy, it would not have succeeded as it did in the Spring of 2010.

It is interesting to consider the reasons why the publishers would be keen to take control of the prices Amazon charges for e-books. Evidence suggests that Amazon was frequently retailing e-books at substantial discounts and even below wholesale costs. One explanation for this is that Amazon was keen to increase demand for Kindle devices. The publishers, on the other hand, might well be concerned about the implications of Amazon dominating the e-book market. Potentially, this would give Amazon significant bargaining power over them.

Of course, such dominance might also have knock-on effects on consumer prices in the long-run. Whether the publishers will be permitted to use agency pricing to mitigate such concerns in the future remains unclear and depends on whether the competition authorities object to agency pricing per se or just the coordinated way in which it was achieved.

As the articles below demonstrate, opinion is strongly divided for and against the judgement against Apple.
