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 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.

In a previous blog, Anyone got a crystal ball?, we reported on the Bank of England’s and other agencies’ difficulty in making forecasts. As the Governor, Mervyn King, said, “There is just enormous uncertainty out there.”
The Bank of England has just published its November Inflation Report. This quarterly publication gives forecasts of inflation, GDP and other indicators. It is clear that forecasting hasn’t become any easier. In his opening remarks, Dr. King says:
Continuing the recent zig-zag pattern, output growth is likely to fall back sharply in Q4 as the boost from the Olympics in the summer is reversed – indeed output may shrink a little this quarter. It is difficult to discern the underlying picture. It is probably neither as good as the zigs suggest nor as bad as the zags imply.

The Inflation Report looks at the various factors affecting aggregate demand, inflation, unemployment and aggregate supply. It is quite clear on reading the report why there is so much uncertainty.

A salutary lesson is to look back at previous forecasts and see just how wrong they have been. The chart above shows the forecasts for GDP made in the Inflation Reports of Nov 2012 and Aug 2011. You can see that they are significantly different and yet just 15 months apart. You might also like to compare the forecasts made a year ago (or even two!) about 2012 with the actual situation today. A good source for this is the Treasury’s Forecasts for the UK economy. This collates the forecasts from a range of independent forecasters.
The inaccuracy of forecasting is an inevitable consequence of a highly interdependent world economy that is subject to a range of economic shocks and where confidence (or lack of it) is a major determinant of aggregate demand. But when firms, governments, individuals and central banks have to make plans, it is still necessary to project into the future and try to forecast as accurately as possible – even though it might mean keeping your fingers firmly crossed.

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.

- How might oil companies react to the growth in this technology?
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.
