Running low on energy

The UK economy faces a growing problem of energy supplies as energy demand continues to rise and as old power stations come to the end of their lives. In fact some 10% of the UK’s electricity generation capacity will be shut down this month.

Energy prices have risen substantially over the past few years and are set to rise further. Partly this is the result of rising global gas prices.

In 2012, the response to soaring gas prices was to cut gas’s share of generation from 39.9% per cent to 27.5%. Coal’s share of generation increased from 29.5% to 39.3%, its highest share since 1996 (see The Department of Energy and Climate Change’s Energy trends section 5: electricity). But with old coal-fired power stations closing down and with the need to produce a greater proportion of energy from renewables, this trend cannot continue.

But new renewable sources, such as wind and solar, take a time to construct. New nuclear takes much longer (see the News Item, Going nuclear). And electricity from these low-carbon sources, after taking construction costs into account, is much more expensive to produce than electricity from coal-fired power stations.

So how will the change in balance between demand and supply affect prices and the security of supply in the coming years. Will we all have to get used to paying much more for electricity? Do we increasingly run the risk of the lights going out? The following video explores these issues.

An auditing of competition

The Big Four are well known: Deloitte, Ernst and Young, KPMG and PWC. They act as auditors for 90% of the UK’s stock-market listed companies. They have a very close relationship with the companies that they audit and because of this have faced criticism of not warning of the financial crisis. A further accusation is that the relationship between auditors and managers has become blurred.

In some sense, there is a problem of divorce of ownership from control. The companies that are audited by the Big Four have shareholders who are interested in profits and their dividends. But they employ managers who are responsible for the day-to-day running of the business. However, there are concerns that the auditors have become more concerned with meeting the interests of the managers and not of the shareholders. It has been suggested that the company’s management tend to ‘present their accounts in the most favourable light, whereas shareholder interests can be quite different.’ Laura Carstensen, the chair of the Audit Investigation Group said:

It is clear that there is significant dissatisfaction amongst some institutional investors with the relevance and extent of reporting in audited financial reports … management may have incentives to present their accounts in the most favourable light, whereas shareholder interests can be quite different.

The Big Four have been criticised for limiting competition in the industry. The Competition Commission has said that companies typically stay with the same auditing firm and this acts to limit competition. One suggestion to encourage competition is to enforce rotation of Auditors. However, the Big Four have said that the market remains competitive, ‘healthy and robust’ and that any enforcement as noted above would not be in the public interest. Other, smaller auditing companies have praised the preliminary report of the Competition Commission. One firm said:

No one solution will achieve market correction, but rather a combination of tendering requirements, encouragement of transparency and dialogue between auditors, companies and investors, and reform of outdated exclusionary practices should provide a backdrop for a healthier FTSE 350 audit market.

The report is not yet final, but the future of the Big Four is somewhat uncertain, especially with the European Commission’s desire to break them up. The following articles look at this industry.

Anyone want to take a bite out of Apple?

The technology sector is highly complex and is led by Apple. However, as the tablet market is continuing to grow, it is becoming increasingly competitive with other firms such as Samsung gaining market share. Although both firms sell many products, it is the growing tablet market which is one of the keys to their continued growth.

Tablet PCs have seen a growth in the final quarter of 2012 to a high of 52.5 million units, according to IDC. Although Apple, leading the market, has seen a growth in its sales, its market share has declined to 43.6%. Over the same period, Samsung has increased its market share from 7.3% to 15.1%. While it is still a huge margin behind Apple in the tablet PC market, Samsung’s increase in sales from 2.2 million to 7.9 million is impressive and if such a trend were to continue, it would certainly cause Apple to take note.

It’s not just these two firms trying to take advantage of this growing industry. Microsoft has recently launched a new tablet PC and although its reception was less than spectacular, it is expected that Microsoft will become a key competitor in the long run. There are many factors driving the growth in this market and the war over market share is surely only just beginning. The chart shows the 75.3% growth in sales in just one year. (Click here for a PowerPoint of the chart.)

A Research Director at IDC said:

We expected a very strong fourth quarter, and the market didn’t disappoint…New product launches from the category’s top vendors, as well as new entrant Microsoft, led to a surge in consumer interest and very robust shipments totals during the holiday season’

Apple has been so dominant in this sector that other companies until recently have had little success in gaining market share. However, with companies such as Samsung and ASUS now making in-roads, competition is likely to become fierce. There are already concerns that Apple’s best days are behind it and its share price reflects this. People are now less willing to pay a premium price for an Apple product, as the innovations of its competitors have now caught up with those of the leading brand name. The following articles consider this growing market.

A 3p delay?

Increases in the cost of living over the past few years have put many families under financial pressure. One of the main factors that has been hurting households is the price of petrol and diesel. Road fuel duty was due to be increased last August, but the Chancellor delayed it in June. However, a planned 3p rise in duty by the Coalition, which has faced rebellion from numerous MPs may now be delayed further, following a hint from the Treasury.

The government has said that it will do everything it can to support struggling families with the cost of living and this has led many to conclude that in the Autumn Statement, the Chancellor will delay the planned 3p rise. Labour was defeated in its efforts to force a delay of the proposed 3p duty rise, as Tory bankbenchers were given this hint that the Treasury would decide to delay the increase anyway. The Economic Secretary to the Treasury said that fuel duty is part of the government’s strategy to help cut the cost of living. He commented that fuel duty was 20% lower in real terms compared to March 2000, when it was at its peak.

If we had continued with the policies of the previous government, quite simply prices would be higher, fuel would be 10p more expensive per litre. I know some will call for a further freeze in fuel duty today. I can assure them this government understands the financial pressures hard-working families are facing. Subject to the constraints of the public finances, this government is determined to help families with the cost of living.

A key economic question to consider is why is fuel one of the products that is frequently taxed? When a tax is imposed on a product, its price will rise and as the law of demand tells us, this will cause people to purchase less of it. But, what is so special about petrol? Why do people continue to purchase petrol even when its price rises? The following articles consider the concerns surrounding the 3p fuel duty rise.

Comet fall from the sky

For those looking to buy larger electrical appliances at cheaper prices, things might be looking up, as Comet have begun heavy discounting after entering administration. Deloitte, as the administrator, will now begin the search for a buyer for this retailer, while Comet aims to raise the funds to rescue the company.

Comet was bought by OpCapita last year, but with poor performance continuing across the 200+ stores, we could be about to see the demise of this retailer. Over 6,000 jobs are now at risk, although Deloitte has maintained that stores will continue to trade and that redundancies will not be made. One of the administrators said:

‘Our immediate priorities are to stabilise the business, fully assess its financial position, and begin an urgent process to seek a suitable buyer which would also preserve jobs.’

The retail environment has inevitably suffered over the past few years, with well-known companies such as Woolworths, Optical Express and JJB Sports (to name a few) entering administration. Comet, therefore seems to be the latest in a long line of sad trading stories. So, which factors have contributed towards the collapse of this giant retailer?

Over the past few years, online retailers have gained a larger and larger market share. These internet retailers do not have the same overhead costs that Comet and other high street retailers face. To open a store in an area where customers are in high supply, premium rents must be paid and this adds to the cost of running any given store. In order to cover these higher costs, higher prices can result and this, together with consumers facing tight budgets, has led many customers to look at the cheaper alternatives online. Deloitte has also said that Comet has been suffering from a lack of credit, which has meant that it has not been able to purchase stock in the run-up to Christmas. Deloitte commented that:

‘The inability to obtain supplier credit for the peak Christmas trading period means that the company had no realistic prospect of raising further capital to build up sufficient stock to allow it to continue trading.’

Concerned customers are naturally emerging, wondering whether items they have ordered and paid for will actually turn up. However, Deloitte’s reassurance that trading will continue may go some way to relieving their concern. The following articles consider how Comet has fallen from the sky.

Questions

  1. Why does the retail environment remain very weak?
  2. Explain why Deloitte suggest that a lack of first time home buyers has played a part in the demise of Comet.
  3. Why has a lack of credit contributed towards Comet’s downfall?
  4. Should customers be concerned about how Comet’s demise (if indeed a buyer is not found) might affect prices in other retailers such as Currys, given that they will now have a larger share of the market?
  5. Why has online trading contributed towards the harsher retail environment for the high street stores? You should think about fixed and variable costs in your answer.
  6. Why are companies such as Apple doing so well relative to other companies, such as Comet and JJB Sports? Is there a secret to their success?
  7. What impact might this collapse have on local labour markets, given Comet employs so many people? Think about the effect on wages, unemployment and on claimants of benefits.

A shock for energy provision

EU environmental legislation is beginning to cause problems in the UK. As it prohibits coal-fired power plants from generating power, they will be forced to close. This means that the UK will be forced to rely more on imported energy, which could lead to price rises, as energy shortages emerge.

Ofgem, the energy regulator has said that the risk of a gas shortage is likely to be at its highest in about 3 years time, as the amount of spare capacity is expected to fall from its current 14% to just 4%. Energy shortages have been a concern for some time, but the report from Ofgem indicates that the predicted time frame for these energy shortages will now be sooner than expected. Ofgem has said that the probability of a black-out has increased from 1 in 3,300 years now to 1 in 12 years by 2015.

The government, however, has said that its Energy Bill soon to be published will set out plans that will secure power supply for the UK. Part of this will be through investment, leading to new methods of generating energy. The Chief Executive of Ofgem, Alistair Buchanan said:

‘The unprecedented challenges in facing Britain’s energy industry … to attract the investment to deliver secure, sustainable and affordable energy supplies for consumers, still remain.’

One particular area that will see growth is wind-farms: a controversial method of power supply, due to the eye-sore they present (to some eyes, at least) and the noise pollution they generate. But with spare capacity predicted to fall to 4%, they will be a much needed investment.

Perhaps of more concern for the everyday household will be the impact on energy prices. As we know, when anything is scarce, the price begins to rise. As energy shortages become more of a concern, the market mechanism will begin to push up prices. With other bills already at record highs and incomes remaining low, the average household is likely to feel the squeeze. The following articles and the Ofgem report considers this issue.

What’s driving the premiums up?

Everyone who drives in the UK is required to take out car insurance. Whilst fully comprehensive is voluntary, it is compulsory to have at least third party insurance, which covers damage to other vehicles. Insurance premiums are calculated based on a number of different variables, such that two people driving the same car may face wildly different costs.

Although there are many insurance companies to choose from, this industry has been referred to the Competition Commission by the OFT as it was ‘worried the structure of the market was making costs and premiums unnecessarily high.’

According to Moneysupermarket, the average cost of car insurance reached a high of £554 in April 2011, but have fallen by £76 since. With tight incomes across the UK for many families, high car insurance premiums is another strain and thus this investigation will come at an apt time, even though the findings of the CC may not be reported for 2 years. The Association of British Insurers (ABI) said that the investigation would:

‘bring much-needed reforms to the market that will, in turn, result in lower car insurance premiums for consumers’.

The problem seems to be that when an individual is involved in an accident and sends their car off for repairs, their insurance company doesn’t have much control over the bills they end up paying, which can be inflated by £155 each time. This therefore leads into higher costs for the insurance company, which are then passed on the driver in the form of an increased premium. Other concerns were that courtesy cars were being offered, at an estimated cost of £560 per vehicle (according to the OFT) and that drivers were using these cars for longer than necessary, once again causing costs to rise.

Altogether, it has been suggested that the actions of the insurance company of ‘not-at-fault’ drivers, car hire companies, repairers and brokers push up the prices for ‘at-fault’ drivers’ insurance companies. Given that any insurance company is just as likely to be the ‘at-fault’ insurance company, they all face rising costs.

Back in May, the OFT had already decided that the car insurance market required a more detailed investigation, because of the ‘dysfunctionality’ of the market. Following a public consultation, the industry will now face an investigation by the CC. One additional area that may be of interest to the CC came to light last year, where it was found that insurance companies were claiming against themselves in a bid to drive up premiums. Although the investigation will take some time, it is still a timely review for many drivers, who have seen the cost of motoring reach record highs. The following articles consider the market for car insurance.

The road ahead

The Office for Budget Responsibility has said that the UK Treasury will face a shortfall of £13bn in motoring taxes within a decade. Although car usage continues to rise putting increasing pressure on the road infrastructure, the greener and more fuel efficient cars being produced are driving down the tax revenues generated from motoring.

A report by the IFS has put forward the case for replacing the existing system of taxes on cars and fuel by a new road charging system. If no such change occurs, the IFS has forecast that with more electric cars and hence lower revenues raised from fuel and vehicle excise duties, the shortfall facing the Treasury would require an increase in fuel duty of some 50%. Instead of this, the solution could be to charge individuals for every mile of road they use, with the ‘price’ varying depending on the degree of congestion. For example, at peak times the price would be higher, where as for those in the countryside where roads are traditionally much quieter, charges would be lower. The IFS said:

‘Such a move would generate substantial economic efficiency gains from reduced congestion, reduce the tax levied on the majority of miles driven, leave many (particularly rural) motorists better off, and provide a stable long-term footing for motoring taxes without necessarily raising net additional revenue from drivers.’

Government policy across the world has been increasingly focused on climate change, with targets for emissions reductions being somewhat ambitious. However, many car manufactures who were told to reduce emissions significantly are on the way to meeting these targets and this success is a key factor contributing towards this new road ‘crisis’ that could soon be facing the government. The following articles consider the possibility of a road charging scheme.

A taxing pint of beer

Binge drinking is a problem that has seen much attention, especially with regards to minimum price controls. However, in this blog, we consider attention in this sector concerning taxation on beer.

Alcohol is widely considered to be a de-merit good with negative externalities imposing external costs on society. This is one of the reasons why taxes are imposed on alcoholic beverages. By increasing production costs to the firms providing these drinks, prices rise and hence the policy aims to discourage consumption.

During the recession, many businesses have seen demand fall and one sector hit particularly hard because of this and very high tax rates has been the local pub community. Duty on beer has increased since 2008 by some 42%. As such, many rural and suburban communities have seen their local watering holes close down and this has led to a campaign by CAMRA to force a debate in Parliament, as a means of protecting ‘one of Britain’s oldest and best loved institutions’. Data suggests that 12 pubs per week are closing down, thus the future of the industry is now under threat. This may also have further damaging effects on local communities, as it may adversely affect the social aspect of communities. Camra’s Chief Executive, Mike Benner said:

‘Whether situated in a small village, city high street, or on the edge of a housing estate, pubs are so central to our society that whole communities can grow around a particular pub.’

According to a study, pubs in Lancashire and the West Midlands have been hardest hit by the pub closures. If pubs don’t pass the tax increase on to consumers in the form of higher prices, then they must bear the burden. If they do pass the tax rises on to consumers then the larger chain firms can increase their market share by selling at a lower price. They are also facing growing pressure from the supermarket industry, which are able to sell cheap alcohol, also contributing to going to the pub becoming an ‘unaffordable activity’. The following articles consider this industry.

What’s in and What’s out?

The rate of inflation in the UK is measured using the Consumer Prices Index (CPI). This is made up of a basket of goods and the ONS updates this ‘basket’ each year to ensure it is representative of what the average UK household buys. The basket contains 700 items, with 180,000 individual prices collected each month.

In recent years, items such as lip gloss have been added to the basket of goods and in the latest adjustment, the ONS has added tablet computers, amongst other things. This is a market that has seen enormous growth. It has been added to the basket as a means of giving a more accurate representation of the price changes faced by the average consumer. The ONS has made it clear that items are not added simply because they are new or removed simply because spending on them has fallen.

‘In each of these cases, the item has not been added because spending has increased or because the product is new on the market … It is purely as part of the rebalancing of the basket to improve its representation of overall price change.’

It is essential that these changes are made each year, as consumer buying habits do fluctuate considerably. One area in particular has been consumer responses to changes in technology. For example, developing and printing colour film has been removed as, with the development of digital cameras, this is no longer reflective of what a representative household spends its money on. Further to this, some items that have previously been used in calculating the RPI have now been added to the CPI, again to give a clearer picture of household spending in the UK.
