The UK government has just given the go-ahead for the building of two new nuclear reactors at Hinkley Point in Somerset. The contract to build and run the power station will go to EDF, the French energy company.

The power station is estimated to cost some £14 billion to build. It would produce around 7% of the UK’s electricity. Currently the 16 nuclear reactors in the UK produce around 19%. But all except for Sizewell B in Suffolk are due to close by 2023, although the lives of some could be extended. There is thus a considerable energy gap to fill in the coming years.

Several new nuclear power stations were being considered to help fill this gap, but with rising capital costs, especially following the Fukushima disaster in Japan, potential investors pulled out of other negotiations. Hinkley Point is the only proposal left. It’s not surprising that the government wants it to go ahead.

All that remains to agree is the price that EDF can charge for the electricity generated from the power station. This price, known as the ‘strike price’, is a government-guaranteed price over the long term. EDF is seeking a 40-year deal. Some low carbon power stations, such as nuclear and offshore wind and wave power stations, have high capital costs. The idea of the strike price is to reduce the risks of the investment and make it easier for energy companies to estimate the likely return on capital.

But the strike price, which will probably be agreed at around £95 per megawatt hour (MWh), is roughly double the current wholesale price of electricity. EDF want a price of around £100 per MWh, which is estimated to give a return on capital of around 10%. The government was hoping to agree on a price nearer to £80 per MWh. Either way, this will require a huge future subsidy on the electricity generated from the plant.

There are several questions being asked about the deal. Is the strike price worth paying? Are all the costs and benefits properly accounted for, including environmental costs and benefits and safety issues? Being an extremely long-term project, are uncertainties over costs, performance of the plant, future market prices for electricity and the costs of alternative forms of power generation sufficiently accounted for? Will the strike price contravene EU competition law? Is the timescale for construction realistic and what would be the consequences of delays? The articles consider these questions and raise a number of issues in planning very long-term capital projects.

From early January to late February 2013, the average pump price of petrol in the UK rose by over 6p per litre – a rise of 4.7% in just seven weeks. There have also been substantial rises in the price of diesel.

The higher prices reflect a rise in the dollar wholesale price of oil and a depreciation in the pound. From 2 January to 21 February the pound fell from $1.63 to $1.53 – a depreciation of 6.1% (see). Crude oil prices (in dollars) rose by just under 7% over this period. With oil imports priced in dollars, a weaker pound pushes up the price of oil in the UK. The price has then been pushed up even higher by speculation, fuelled by the belief that prices have further to rise.

The higher price of road fuel, plus the general squeeze on living standards from the recession, with prices rising faster than wages, has caused a reduction in the consumption of road fuel. Petrol sales have fallen to their lowest level for 23 years. Sales in January 2013 were 99m litres down on the previous month’s sales of 1564m litres (a fall of 6.3%).

Not surprisingly motorists’ groups have called for a reduction in fuel taxes to ease the burden on motorists. They also argue that this will help to drive recovery in the economy by leaving people with more money in their pockets.

Equally not surprisingly, those concerned about the environment have welcomed the reduction in traffic, as have some motorists who like the quieter roads, allowing journey times to be cut, with resulting reductions in fuel consumption per mile.

The following videos and articles discuss the causes of the most recent fuel price rises and also examine the responsiveness of demand to these higher prices and to the reductions in real incomes.

As resources become scarce, the price mechanism works to push up the price (see, for example, Box 9.11 in Economics 8th ed). If you look at the price of petrol over the past few decades, there has been a general upward trend – part of this is due to growth in demand, but part is due to oil being a scarce resource. Many millions have been spent on trying to find alternative fuels and perhaps things are now looking up!

Air Fuel Synthesis, a small British company, has allegedly managed to make ‘petrol from air’. Following this, the company has unsurprisingly received finance and investment offers from across the world. However, the entrepreneur Professor Marmont has said that he does not want any company from the oil industry to get a stake in this firm. This doesn’t mean that investment is not needed or on the cards, as in order to increase production of petrol from thin air financing is needed. Professors Marmont said:

We’ve had calls offering us money from all over the world. We’ve never had that before. We’ve made the first petrol with our demonstration plant but the next stage is to build a bigger plant capable of producing 1 tonne of petrol a day, which means we need between £5m and £6m

Whilst the process appears to be a reality, Air Fuel Synthesis is a long way from being able to produce en masse. However, it does offer an exciting prospect for the future of petrol and renewable energy resources in the UK. At the moment oil companies appear to be uninterested, but if this breakthrough receives the financing it needs and progress continues to be made, it will be interesting to see how the big oil companies respond. The following articles consider this break-through.

The energy sector has a history of criticism with regards to prices and practices. In the past, Ofgem have tried to make the sector more competitive, by ensuring that price comparisons are easier. At the beginning of this year, many of the big six providers announced price cuts, but within the next few weeks, we will see the reverse occurring, as energy prices begin to rise.

British Gas has announced price rises of 6% from 16th November that will affect over 8 million customers by adding approximately £80 per year to the annual dual fuel bill. Npower will also put its prices up 10 days later (8.8% for gas and 9.1% for electricity), creating higher bills for 3 million people.

In January of this year, when we saw energy prices fall, it was not solely due to Ofgem’s findings. We had a relatively mild winter, which reduced the demand for energy and this fed into lower prices. As the winter now approaches once more, demand for energy will begin to increase, feeding into prices that are now higher.

Furthermore, the energy companies have said that a range of external factors are also adding to their costs and putting increasing pressure on them to increase their charges. Npower’s Chief Commercial Officer said:

“There is never a good time to increase energy bills, particularly when so many people are working hard to make ends meet…But the costs of new statutory schemes, increases in distribution charges and the price of gas for the coming winter are all being driven up by external factors, for example government policy”

Significant investment is needed in the energy sector. Energy companies are required to set aside money for maintaining and improving the national grid and investing in renewable energy, such as wind and solar power. In order for the energy companies to fund these investments, more money must be raised and the logical method is to put up prices. However, critics are simply blaming ‘these very big lazy companies’ who are passing ‘above-inflation price rises’ onto already squeezed households.

Part of this is undoubtedly to do with the market structure of this sector. A typical oligopoly creates a market which, under certain circumstances, can be highly competitive, but because of barriers to entry that prevent new firms from entering the market may charge higher prices and be inefficient. Indeed, Ofgem has plans to reduce the power of the main energy providers by forcing them to auction off some of the electricity they generate. The aim of this is to free up the market and make it more competitive.

While only three providers have announced price rises, it is inevitable that the other three will follow. The relative increases will create incentives for consumers to switch providers, but crucial to this is an ability to understand the different tariffs on offer and lack of clarity on this has been a big criticism previously levelled at the energy sector. Indeed, half of UK customers have never switched energy providers. Perhaps this is the time to think about it, firstly as a means of saving money and secondly as a means of putting the energy companies in competition with each other. The following articles consider this market.

Virgin’s franchise to run the West Coast Main Line from London to Birmingham, Manchester, Liverpool, Glasgow and Edinburgh was due to expire in December. The Department of Transport thus invited tenders to run a new 13-year franchise, worth around £5 billion, and on 15 August announced that the franchise had been awarded to FirstGroup. It had bid substantially more than Virgin.

Virgin immediately challenged the decision, arguing that FirstGroup’s figures were flawed. According to the second BBC article below:

It argued that FirstGroup’s revenue projections were wildly optimistic – that passenger growth of 6% a year was unlikely given that Virgin had seen growth of 5% a year from a much lower base. This level of passenger growth would have seen FirstGroup’s revenue from the franchise grow by more than 10% a year, which was simply unrealistic, Virgin argued.

And it is not alone. “Everybody in the industry thought that this bid was not sustainable and that the risks had not been taken into account by the Department for Transport,” says rail industry expert Christian Wolmar.

If revenue targets are not met, the franchisee doesn’t have the money to pay the government the promised fee for the contract, which in FirstGroup’s case was back-loaded towards the end of the 13-year term.

After making its decision, the Transport Secretary at the time, Justine Greening, said that the process of assessing the bid was robust and fair and conducted with due diligence. Sir Richard Branson of Virgin strongly and publicly disagreed and Virgin decided to take the Department of Transport to court. The court case was scheduled to begin on 4 October.

However, in preparing its case to put to the court, the Department of Transport uncovered significant errors in the evaluation of the bids. These errors involved the overestimation of passenger numbers, the undervaluation of risk and a failure to take inflation into account. The errors stemmed from inputting the data incorrectly.

The errors were so serious that the new Transport Secretary, Patrick McLoughlin, on the day before the court case was due to begin, announced that he was scrapping the contract to FirstGroup and would invite new bids. All four of the original bidders would have their costs refunded, amounting to some £40 million.

The minister also announced that he was setting up two reviews. One would seek to establish just what went wrong in the assessment of the West Coat Main Line bids and what lessons could be learned. This is due to report at the end of October. The other review would examine the wider rail franchise programme and how bids are appraised. In the meantime, three other franchise competitions had been ‘paused’ pending the results of this second review, due to report in December.

The articles look at the problems of assessing bids and properly taking into account risks associated with both revenue and cost projections. Not surprisingly, they also look at the politics of this amazing and unprecedented U-turn

Rail companies will be permitted to raise average regulated rail fares next year by 6.2%. Not surprisingly, this has been met with dismay and anger by rail travellers, especially long-distance commuters, who could see their annual season tickets going up by several hundred pounds.

Some fares, such as advance tickets, are unregulated. Others, such as anytime, off-peak and season tickets, are regulated by the government. The formula for working out permitted price rises for regulated fares is RPI plus 3%, where RPI is the July annual inflation rate based on the retail price index.

The RPI figure was announced by the ONS on 14 August and was a surprisingly high 3.2% – up from 2.8% in June: see Table 21 in the ONS’s CPI And RPI Reference Tables, July 2012. (Click here for a PowerPoint of the chart on the left.) Hence average fares can rise by 3.2% + 3% = 6.2%.

Rail travellers are angry on three counts:

First, the RPI measure of inflation is generally around 0.5% higher than the CPI measure (which is used for working out public-sector pay increases and the uprating of pensions and benefits). The July figure for CPI inflation was 2.6%.

Second, the extra 3% added on top of RPI means that that rail fares are going up more rapidly than other prices, and incomes too. The reason given for this is to shift the burden of funding the railways from the taxpayer to the traveller.

Third, the formula applies to average fares. Rail companies can raise particular regulated fares by up to 5 percentage points more than the formula provided they raise other fares by less than the formula. Thus some fares are set to rise by 11.2% – including some of the most expensive season tickets.

The government justified the increases by arguing that the higher fares will allow more investment by the rail companies, which could result in lower costs in the future. Nevertheless, two thirds of the revenue from the above-inflation increases will go to the government and only one third to the rail companies.

A campaign to introduce a tax on disposable plastic bags in England has been launched by various pressure groups, including The Campaign to Protect Rural England (CPRE), Keep Britain Tidy, the Marine Conservation Society and Surfers Against Sewage. Plastic bags, they maintain, litter streets and the countryside and pollute the seas, where they cause considerable damage to marine life.

They propose a tax of 5p per bag, which would be passed on to consumers. Such a levy has already been introduced in Wales in October 2011. As a result, plastic bag use in Wales has dropped dramatically (see also the full report from the Welsh Government). The Scottish Government and the Northern Ireland Assembly are also planning introducing similar charges.

Many other governments have introduced taxes, charges or bans on plastic bags and many more are considering introducing such measures. Ireland introduced a 15 euro cent charge on single-use plastic bags as far back as 2002 and saw a 94% reduction in plastic bag use (328 per person per year to 21). The charge was raised to 22 euro cents in 2007 after bag use rose to 30 per person.

Other countries have banned plastic bags altogether: some, such as Rwanda and Somalia have banned all plastic bags; others, such as China and South Africa have banned very thin bags; others, such as Italy, have banned non-biodegradable ones.

In the USA, various states or districts have introduced levies and in the EU, where more than four billion bags are thrown away each year, the European Commission will soon publish proposals for limiting the use of plastic bags.

So what are the arguments for limiting the use of plastic bags? Why is it not enough to leave things simply to the market? And if the use of plastic bags is to be reduced, what’s the most efficient way of doing so? Are there any problems with alternatives to plastic bags? The following articles and reports consider these questions?

Barclays’ Chief Executive, Bob Diamond, has resigned following revelations that Barclays staff had been involved in rigging the LIBOR in the period 2005–9, including the financial crisis of 2007–9.

So what is the LIBOR; how is it set; what were the reasons for Barclays (and other banks, as will soon be revealed) attempting to manipulate the rate; and what were the consequences?

The LIBOR, or London interbank offered rate, is the average of what banks report that they would have to pay to borrow from one another in the inter-bank market. Separate LIBORs are calculated for 15 different lending periods: overnight, one week, one month, two months, three months, six months, etc. The rates are set daily as the average of submissions made to Thomson Reuters by some 15 to 20 banks (a poll overseen by the British Bankers’ Association). Thomson Reuters then publishes the LIBORs, along with all of the submissions from individual banks which are used to calculate it.

Many interest rates around the world are based on LIBORs, or their European counterpart, EURIBORs. They include bond rates, mortgage rates, overdraft rates, etc. Trillions of dollars worth of such assets are benchmarked to the LIBORs. Thus manipulating LIBORs by even 1 basis point (0.01%) can result in millions of dollars worth of gains (or losses) to banks.

The charge, made by the Financial Services Authority, is that Barclays staff deliberately under- or overstated the rate at which the bank would have to borrow. For example, when interbank loans were drying up in the autumn of 2008, Barclays staff were accused of deliberately understating the rate at which they would have to borrow in order to persuade markets that the bank was facing less difficulty than it really was and thereby boost confidence in the bank. In other words they were accused of trying to manipulate LIBORs down by lying.

As it was the LIBORs were rising well above bank rate. The spread for the one-month LIBOR was around 1 to 1.2% above Bank Rate. Today it is around 0.1 to 0.15% above Bank Rate. Without lying by staff in Barclays, RBS and probably other banks too, the spread in 2008 may have been quite a bit higher still.

The following articles look at the issue, its impact at the time and the aftermath today.

World leaders have been meeting in Rio de Janeiro at a United Nations Conference on Sustainable Development. The conference, dubbed ‘Rio+20′, refers back to the first UN Conference on Environment and Development (UNCED) held in Rio 20 years ago in June 1992.

The 1992 conference adopted an Agenda 21. It was “comprehensive plan of action to be taken globally, nationally and locally by organizations of the United Nations System, Governments, and Major Groups in every area in which human impacts on the environment.”

The 2012 conference has looked at progress, or lack of it, on sustainability and what needs to be done. It has focused on two major themes: “how to build a green economy to achieve sustainable development and lift people out of poverty, including support for developing countries that will allow them to find a green path for development; and how to improve international coordination for sustainable development.” Issues examined have included decent jobs, energy, sustainable cities, food security and sustainable agriculture, water, oceans and disaster readiness.

But just what is meant by sustainable development? The conference defines sustainable development as that which meets the needs of the present without compromising the ability of future generations to meet their own needs. “Seen as the guiding principle for long-term global development, sustainable development consists of three pillars: economic development, social development and environmental protection.”

The articles below look at prospects for national and global sustainability. They also look at a new measure of national wealth, the Inclusive Wealth Index (IWI). This index has been developed under the auspices of the International Human Dimensions Programme on Global Environmental Change (IHDP) and published in its Inclusive Wealth Report 2012 (see report links below).

The IWR 2012 was developed on the notion that current economic production indicators such as gross domestic product (GDP) and the Human Development Index (HDI) are insufficient, as they fail to reflect the state of natural resources or ecological conditions, and focus exclusively on the short term, without indicating whether national policies are sustainable.

The IWR 2012 features an index that measures the wealth of nations by looking into a country’s capital assets, including manufactured, human and natural capital, and its corresponding values: the Inclusive Wealth Index (IWI). Results show changes in inclusive wealth from 1990 to 2008, and include a long-term comparison to GDP for an initial group of 20 countries worldwide, which represent 72% of the world GDP and 56% of the global population. (Click on chart for a larger version.)

So will growth in IWI per capita be a better measure of sustainable development than growth in GDP per capita? The articles also consider this issue.

No market is perfect and when the market mechanism fails to deliver an efficient allocation of resources, we say the market fails and hence there is justification for some government intervention. From a monopolist dominating an industry to a manufacturing firm pumping out pollution, there are countless examples of market failure.

The Guardian is creating a guide to climate change, covering areas from politics to economics. The problem of climate change has been well documented and this blog considers a particular issue – the case for climate change or the environment as a market failure. In many cases just one market failure can be identified, for example an externality or a missing market. However, one of the key problems with climate change is that there are several market failures: externalities in the form of pollution from greenhouse gases; poor information; minimal incentives; the problem of the environment as a common resource and the immobility of factors of production, to name a few. Each contributes towards a misallocation of resources and prevents the welfare of society from being maximised.

When a market fails, intervention is justified and economists argue for a variety of policies to tackle the above failures. In a first-best world, there is only one market failure to tackle, but in the case of the environment, policy must be designed carefully to take into account the fact that there are numerous failings of the free market. Second-best solutions are needed. Furthermore, as the problem of climate change will be felt by everyone, whether in a developed or a developing country, international attention is needed. The two articles below are part of the Guardian’s ultimate climate change guide and consider a huge range of economic issues relating to the problem of environmental market failure.
