Much has been written on Margaret Thatcher following her death at the age of 87 on April 8. But getting a calm assessment of both her time in office and her legacy is not easy. And it’s clear why: she created both stronger loyalty and stronger opposition than any other UK Prime Minister.

As economists, however, we should try to be as dispassionate as possible in assessing the effects of policies. There is always a normative question of the relative desirability of different economic outcomes – and you will have your own views on the relative importance of objectives such as economic growth, greater equality and greater social cohesion – but to determine cause and effect, or at least correlation, requires a careful examination of the evidence. Also, drawing lessons for future policy requires a careful modelling of the economy and the effects of changing economic variables.

The following articles have been selected from the hundreds that have appeared in the press in the past few days. Whilst they cannot be claimed to be totally ‘objective’, taken together they give a good overview of her economic policies and her economic legacy.

You may well have been surprised by the amount of coverage of her death and at the fervour of her supporters and critics. But this bears witness to the huge effect she had on both the political scene and on the UK economy – for good or bad.

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.

It’s a relatively common dish to see on a menu at a restaurant: mackerel. This particular fish has been promoted as a healthy and sustainable dish, but now its sustainability is coming into question and the Marine Conservation Society has taken it off its ‘fish to eat’ list. My brother Hugh is a marine biologist and often comments on which fish we should be avoiding due to sustainability issues (especially given how much I like fish!) So, how is this an economics issue?

There a couple of key things to pick out here. Firstly, with the conservationists’ warning of this issue of unsustainability, they have been asking consumers to reduce the amount of mackerel they buy. This will naturally have an impact on fisherman. If consumers do listen to the conservationists and hence reduce their demand for mackerel, we could see a fall in the price of this fish and a reduction in the fishermen’s turnover. It could be that we see a switch in consumption to other more sustainable fish, especially if we see some form of intervention.

Another area concerning economics is the idea of over-fishing. For years, there have been disputes over who has the rights to these fish stocks. In the past, the Faroe Isles and Iceland have increased their quotas significantly, as mackerel appear to have migrated to their shores, contributing to this question of sustainability. Iceland and the Faroe Isles have ‘unilaterally agreed their quotas … as they are not governed by the common fisheries policy’.

The question is: when fisherman catch one additional mackerel, what are they considering? Do they think about the private benefit to them (or their company) or do they consider the external cost imposed on others? Whenever one fish is taken from the sea, there is one less fish available for other fishermen.

This leads to over-consumption of fish and contributes towards the well-documented depletion of fish stocks and ‘The Tragedy of the Commons’, if account is not taken of the external cost imposed on other fishermen.

The total catch is now far in excess of what has been scientifically recommended and previously agreed upon by all participating countries. Negotiations to introduce new catch allowances have so far failed to reach agreement.

There are hopes that an international policy on quotas can be agreed to ensure mackerel levels return to or remain at a sustainable level. However, at present no progress has been made. Until some form of an agreement is reached, fishermen around Iceland and the Faroe Isles will continue to battle against the conservationists. The following articles consider this fishy topic.

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

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.

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?
