After weak Christmas trading, Tesco issued a profit warning – its first in 20 years. Following this, their shares fell in value by some £5bn, but this was met with an announcement of the creation of 20,000 jobs in the coming years, as part of a project to train staff, improve existing stores and open new ones. Yet, Tesco has reported another quarter of falling sales.

Trading times have been challenging and the fact that the UK’s biggest supermarket is struggling is only further evidence to support this. In the 13 weeks to the 26th May 2012, Tesco reported a decline in like-for-like sales of 1.5%. Although much of the £1bn investment in Tesco is yet to be spent, the fact that sales have fallen for a full year must be of concern, not only to its Chief Executive, but also to analysts considering the economic future for the UK.

Consumer confidence remains low and together with tight budgets, shoppers are continuing to be very cautious of any unnecessary spending. Part of Tesco’s recent drive to drum up sales has been better customer service and a continuing promotion war with the other supermarkets. This particular sector is highly competitive and money-off coupons and other such promotions plays a huge part in the competitive process. Whilst low prices are obviously crucial, this is one sector where non-price competition can be just as important.

Although Tesco sales in the UK have been nothing to shout about – the Chief Executive said their sales performance was ‘steady’ – its total global sales did increase by 2.2%. The Chief Executive, Mr Clarke said:

‘Internationally, like-for-like sales growth proved resilient, despite slowing economic growth in China…Against the backdrop of continued uncertainty in the eurozone, it is pleasing to see that our businesses have largely sustained their performance.’

A boost for UK sales did come with the Jubilee weekend and with the Olympics just round the corner, Tesco will be hoping for a stronger end to the year than their beginning. The following articles consider Tesco’s sales and the relative performance of the rest of the sector.

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.

Questions

  1. Illustrate the effect of a tax being imposed on petrol. What happens to the equilibrium price and quantity?
  2. Despite fuel duty pushing up the price of petrol, why has there been such a small decline in the quantity of petrol individuals use?
  3. Evaluate the case for and against a road charging scheme.
  4. Why are tax revenues from motoring expected to decline over the next decade?
  5. Climate change has become an increasingly important focus of government policy. To what extent is the current road ‘crisis’ a positive sign that policies to tackle climate change are working?
  6. If a road charging scheme went ahead and prices were varied depending on traffic, time etc, what name would you give to this strategy?
  7. Why would it be possible to charge a higher price at peak times and a lower price for cars using country roads?
  8. Is there an argument for privatising the road network? Is it even possible?

Centrica, owners of British Gas, has warned that electricity and gas prices in the UK are set to rise in the autumn. Centrica blames this on the expected rise in the costs of wholesale gas and other non-energy inputs.

One of the other ‘big six’ energy suppliers, E.On, has responded by saying that it will not raise energy prices this year. Whether it will raise prices after 1 Jan next year remains to be seen.

Last autumn, household energy prices rose substantially: between 15.4% and 18% for gas and between 4.5% and 16% for electricity. This spring, in response to lower wholesale energy prices, suppliers cut prices for either electricity or gas (but not both) by around 5%.

The government and various pressure groups are encouraging consumers to use price comparison sites to switch to a cheaper supplier. The problem with this is that supplier A may be cheaper than supplier B one month, but B cheaper than A the next. Nevertheless, switching does impose some degree of additional competitive pressure on suppliers.

More powerful pressure could be applied by ‘collective switching’. This is where a lot of people switch via an intermediary company, which sources a deal from an energy supplier. This collective buying is a form of countervailing power to offset the oligopoly power of the suppliers. Such schemes are being encouraged by the Energy Minister, Ed Davey.

The other approach, apart from doing nothing, is for Ofgem, the energy regulator, to impose tough conditions on pricing. But at present, Ofgem’s approach has been to try to make the market more competitive (see also), rather than regulating prices.

Questions

  1. What are the barriers to entry in the electricity supply market?
  2. How competitive is the retail energy market at present?
  3. To what extent do price comparison sites put pressure on energy companies to reeduce prices or limit price increases?
  4. What scope is there for collective buying of gas and electricity from the six energy suppliers by (a) households; (b) firms?
  5. Assess Ofgem’s package of proposals for a simpler and more competitive energy market.

Cartels are formal collusive agreements between firms, typically to fix prices, restrict output or divide up markets. As in the case of monopoly, the lack of competition may harm consumers, who are likely to have to pay higher prices. This, as economic theory demonstrates, results in a reduction in overall welfare.

For this reason competition authorities throughout the world now impose substantial fines on firms found to be involved in collusive activities and participants also face the threat of substantial jail sentences.

One of the most famous cartels is the Organization of Petroleum Exporting Countries (OPEC). This is an agreement between 12 countries to limit their production of oil. The OPEC cartel has been in place for over 50 years. Arguably, the intergovernmental nature of the cartel and political ramifications of intervening have meant that OPEC has been able to operate free from prosecution for so long.

However, very interestingly Freedom Watch, a US public interest group founded by a former US Department of Justice lawyer, has this week filed a lawsuit against OPEC for violation of competition laws. Quoted in the above press release, Larry Klayman, the founder of Freedom Watch, says that:

These artificially-inflated crude oil prices fall hard on the backs of Americans, many of whom cannot afford to buy gasoline during these severely depressed economic times.

Furthermore, how some of the members use the profits gained from the cartel is also called into question. He also goes on to suggest that the lack of intervention from US government agencies may be because the leaders of both political parties:

… line their pockets from big oil interests and are just sitting back and not doing anything.

This is not the first time that Freedom Watch has served a lawsuit on OPEC. In 2008, at an OPEC meeting in Florida:

In a bold move in front of members of the news media, Freedom Watch Chairman and Chief Legal Counsel Larry Klayman literally jumped out from behind a line of TV cameras and microphones on Friday, October 24, to serve a complaint on an OPEC oil minister.

That complaint was unsuccessful.

It will be fascinating to see the outcome of this latest case and, if successful, the implications for OPEC – updates to appear on this blog in due course.

John Von Neumann was a mathematician and one of his many accolades was applying mathematics and his observations of traditional games to create a new discipline – Game Theory. This involves a mathematical approach to decision making whereby different strategies can be assessed. It a tool that not only can be used in Economics, but also can be applied to a broad range of areas and fields of study.

Just as I arrived at work, I was listening to Radio 4 and heard the introduction to the programme In our Time. This one in particular caught my attention because of the name mentioned – Von Neumann, and after arriving in my office I then listened to the discussions surrounding game theory.

The main link is to the discussion from BBC Radio 4, led by Melvyn Bragg, with guests: Ian Stewart, a Professor of Mathematics from the University of Warwick; Andrew Colman, a Professor of Psychology at the University of Leicester and Richard Bradley, a Professor of Philosophy from the LSE. I’ll keep it brief and simply say enjoy!
