Calls for an independent Scotland have focused on a variety of economic issues. These have included taxation, government spending, currency, fiscal policy and monetary policy. However, the BBC News article below looks at another factor which may be affected by a ‘yes’ vote – the price of stamps.
Having just returned from 10 days in the Highlands, I certainly agree with the BBC article that it would be an expensive business to deliver to the remotest parts of Scotland and would definitely require ‘trains, planes, ferries, Land Rovers and vans’ and, in an extreme case, a fishing boat.
So is the price we pay for postage to less rural areas of the UK used to subsidise the higher costs of delivery to the remotest parts of Scotland and, in particular, to the small islands off the Scottish coastline? What would a ‘yes’ vote mean for the cost of stamps in Scotland and in the remainder of the UK? The following articles consider this rather odd question.
Why postage should be cheaper in UK if Scots vote ‘Yes’ BBC News, Brian Milligan (19/4/14)
Tories warn over post service costs The Courier (6/4/14)
Questions
- What happened when the Royal Mail was privatised?
- What are the benefits and costs of privatisation?
- Using a cost and revenue diagram, explain how the different costs of delivery between urban parts of the UK and the remotest parts of Scotland should be reflected in different prices of postage.
- If the price of postage is the same for delivery everywhere in the UK, use your diagram to explain how this happens.
- What does your diagram suggest will happen to the price of postage stamps if a ‘subsidy’ is no longer available?
The energy market is complex and is a prime example of an oligopoly: a few dominant firms in the market and interdependence between the suppliers. Over 95% of the market is supplied by the so-called ‘big six’ and collectively they generate 80% of the country’s electricity. There are two further large generators (Drax Power Limited and GDF Suez Energy UK), meaning the electricity generation is also an oligopoly.
This sector has seen media attention for some years, with criticisms about the high profits made by suppliers, the high prices they charge and the lack of competition. Numerous investigations have taken place by Ofgem, the energy market regulator, and the latest development builds on a simple concept that has been a known problem for decades: barriers to entry. It is very difficult for new firms to enter this market, in particular because of the vertically integrated nature of the big six. Not only are they the suppliers of the energy, but they are also the energy generators. It is therefore very difficult for new suppliers to enter the market and access the energy that is generated.
Ofgem’s new plans will aim to reduce the barriers to entry in the market and thus make it easier for new firms to enter and act as effective competitors. The big six energy generators are vertically integrated companies and thus effectively sell their energy to themselves, whereas other suppliers have to purchase their energy before they can sell it. The regulator’s plans aim to improve transparency by ensuring that wholesale power prices are published two years in advance, thus making it easier for smaller companies to buy energy and then re-sell it. Andrew Wright, the Chief Executive of Ofgem, said:
These reforms give independent suppliers, generators and new entrants to the market, both the visibility of prices, and [the] opportunities to trade, [that] they need to compete with the largest energy suppliers…Almost two million customers are with independent suppliers, and we expect these reforms to help these suppliers and any new entrants to grow.
Although such reforms will reduce the barriers to entry in the market and thus should aim to increase competition and hence benefit consumers, many argue that the reforms don’t go far enough and will have only minor effects on the competitiveness in the market. There are still calls for further reforms in the market and a more in-depth investigation to ensure that consumers are really getting the best deal. The following articles consider this ongoing saga and this highly complex market.

In market capitalism, the stock of manufactured capital provides a flow of output. The profitability of the use of that capital depends on the cost of investing in that capital and the cost of using it, and on the flow of revenues from that capital. Discounted cash flow techniques can be used to assess the profitability of a given investment in capital; the flows of costs and revenues are discounted at a market discount rate to give a net present value (NPV). If the NPV is positive (discounted revenues exceed discounted costs), the investment is profitable; if it is negative, the investment is unprofitable. (See Economics, 8th edition, section 9.3.)
There may be market imperfections in the allocation of investment, in terms of distorted prices and interest rates. These may be the result of market power, asymmetry of information, etc., but in many cases the market allows capital investment to be allocated relatively efficiently.
Natural capital
This is not the case with ‘natural capital’. Natural capital (see also) is the stock of natural resources and ecosystems that, like manufactured capital, yields a flow of goods and services into the future.
Natural capital, whilst it can be improved or degraded by human action, is available without investment. Thus the natural capital of the oceans yields fish, the natural capital of the skies yields rain and the natural capital of forests reduces atmospheric CO2.
Even though some natural capital is owned (e.g. private land), much is a common resource. As such, it is free to use and tends to get overused. This is the Tragedy of the Commons – see, for example, the following news items: A modern tragedy of the commons and Is there something fishy going on?.
Natural capital accounting
But would it be possible to give a value to both the stock of natural capital and the goods and services provided by it? Would this environmental accounting enable governments to tax or subsidise firms and individuals for their use or enhancement of natural capital?
On 21 and 22 November 2013, the first World Forum on Natural Capital took place in Edinburgh. This brought together business leaders, politicians, economists, environmentalists and other scientists to discuss practical ways of taking natural capital into account in decision making. Central to the forum was a discussion of ways of valuing natural capital, or ‘natural capital accounting’. As the forum site states:
Natural capital accounting is a rapidly evolving new way of thinking about how we value the economic benefits we derive from our natural environment. The World Forum on Natural Capital will bring together world-class speakers, cutting edge case studies and senior decision makers from different sectors, in order to turn the debate into practical action.

But if natural capital is not owned, how is it to be priced? How will the costs and benefits of its use be valued? How will inter-generational effects be taken into account? Will firms price natural capital voluntarily if doing so reduces their profits? Will firms willingly extend corporate social responsibility to include corporate environmental responsibility? Will governments be prepared to introduce taxes and subsidies to internalise the costs of using natural capital, even if the effects extend beyond a country’s borders? Will natural capital accounting measure purely the effects on humans or will broader questions of maintaining and protecting environmental diversity for its own sake be taken into account? These are big questions and ones that various organisations are beginning to address.
Despite problems of measurement and incentives, sometimes there are clear economic benefits from careful evaluation and management of natural capital. Julia Marton-Lefèvre is Director General of the International Union for Conservation of Nature (IUCN). According to the first Guardian article below:
Her favourite example of natural capital working in practice comes from Vietnam, where “planting and protecting nearly 12,000 hectares of mangroves cost just more than $1m but saved annual expenditures on dyke maintenance of well over $7m. And that only accounts for coast maintenance: mangroves are also nurseries for fish, meaning livelihoods for fishing and source of nutrients … “
One organisation attempting to value natural capital is The Economics of Ecosystems and Biodiversity project (TEEB). It also looks at what organisational changes are likely to be necessary for the management of natural capital.
Based on data collected from 26 early adopter companies (60% of them with $10 Billion+ revenues each) across several industry sectors this provides real life evidence on the drivers and barriers for natural capital management.
Pricing the environment is a highly controversial issue. Critics claim that the process can easily be manipulated to serve the short-term interests of business and governments. What is more, where tradable permits markets have been set up, such as the EU’s Emissions Trading Scheme (ETS), prices have often been a poor reflection of social costs and have been open to manipulation. As Nick Dearden, director of the World Development Movement (WDM), says:
It is deeply ironic that the same financial markets that caused the economic crisis are now seen as the solution to our environmental crisis. It’s about time we learnt that financial markets need to be reined in, not expanded. Pricing these common resources on which people depend for their survival leaves all of us more exposed to the forces of the global economy, and decisions about whether or not to protect them become a matter of accounting.
The measurement of natural capital and setting up systems to internalise the costs and benefits of using natural capital is both complex and a political minefield – as the following articles show.

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.

- 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.'”
HS2 has been a controversial topic for some time now. Between the disruption it would cause to countless neighbourhoods and the protests that have emerged and the debate about the cost effectiveness of the project, it’s been in the news a fair amount. The transport network in the UK needs improving, not only for businesses located here, but also to encourage more investment into the country. HS2 is one of the solutions offered.
The latest estimate for the cost of HS2 is over £40 billion. However, many suggest that the benefits HS2 will bring do not cover the full costs. Furthermore, as noted above, other concerns include the disruption that it will bring to countless households who will be living along the proposed routes. Cost benefit analysis have been carried out to determine the viability of the project, but they are invariably difficult to do. As they involve determining all of the private and social costs and benefits and putting a monetary estimate onto them, there will inevitably be factors that are over-looked, under-estimated or over-estimated. The suggestions here are that the costs have been under-estimated and the benefits over-estimated.
In September, KPMG produced a report that estimated the overall benefit to the UK economy would be a boost to growth of 0.8%, which would benefit many businesses and communities. The British Chambers of Commerce said:
Business communities in dozens of cities and towns, from many parts of the UK, remain strongly supportive of HS2.
The railway network is also approaching full capacity and this is one of the reasons why HS2 has been proposed. A government source said:
We need to do something because our railways are nearly full, but the alternative to HS2 is a patch and mend job that would cause 14 years of gridlock, hellish journeys and rail replacement buses … The three main routes to the north would be crippled and the economy would be damaged.
However, this report has faced criticism, in particular because it ignored a variety of supply-side constraints and because they argue it would be more effective to simply update the existing network.
However, a new government-commissioned report has suggested that this alternative to HS2 would involve 14 years of weekend route closures and much longer journey times. However, those in favour of updating existing routes have said that this new report commissioned by the government is ‘a complete fabrication’. Hilary Wharf of the HS2 Action Alliance commented:
This government-funded report is a complete fabrication. The main alternative to HS2 involves longer trains and reduced first-class capacity to provide more standard class seats…No work is required at Euston to deliver the necessary capacity increase. Work is only required at three locations on the WCML [West Coast Main Line], and this is comparable to the work being carried out on the route at present.
The debate regarding HS2 will continue for the time being and it is just another area that is fuelling the political playing field. Whatever is done, the rail network certainly requires investment, whether it is through HS2 or upgrades to the existing routes. The following reports and articles consider the latest developments and controversy regarding HS2.
