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.

Questions
- What was being forecast for economic growth and inflation for 2012 (a) one year ago; (b) two years ago?
- What are the main reasons for the inaccuracy of forecasts?
- How might forecasting be made more reliable?
- If sentiment is a key determinant of economic activity, how might politicians increase the confidence of firms and consumers? What are the political constraints on doing this?
- Explain the following statement from the Guardian article: “The problem … is that last decade’s tailwind has become this decade’s headwind.” Why is it difficult to forecast the strength of this ‘headwind’?
- How useful is it to use past trends as a guide to the future course of the economy?
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.

Questions
- Explain the way in which the price mechanism works as resources become scarce. Use a diagram to help your explanation.
- As raw materials become scarce, prices of the goods that use them to work or require them to be produced will be affected. Explain this interdependence between markets.
- Why is investment from an oil company such a concern for Professor Marmont?
- Why is there unlikely to be any impact in the short run from this new breakthrough?
- If such a technology could be put into practice, what effect might this have on the price of petrol?
- 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.

Original post
As a resident of Bristol it is with considerable interest that I’m following the development of the Bristol pound, due for launch in September 2012. One Bristol pound will be worth one pound sterling.
The new currency will be issued in denominations of £1, £5, £10 and £20 and there is a local competition to design the notes. Participating local traders will open accounts with Bristol Credit Union, which will administer the scheme. It has FSA backing and so all deposits will be guaranteed up to £85,000.
The idea of a local currency is not new. There are already local currencies in Stroud in Gloucestershire, Totnes in Devon, Lewes in East Sussex and Brixton in south London. The Bristol scheme, however, is the first to be introduced on a city-wide scale. The administrators are keen that use of the currency should be as easy as possible; people will be able to open accounts with Bristol Credit Union, pay bills online and pay shopkeepers by mobile phone text message (a system used in many countries, but not in the UK).
As the money has to be spent locally, the aim is to help local business, of which more han 100 have already signed up to the scheme. Bristol has a large number of independent traders – in fact, the road where I live is off the Gloucester Road, which has the largest number of independent traders on one street in the UK. The organisers of the Bristol pound are determined to preserve the diversity of shops and prevent Bristol from becoming a ‘clone town’, with high streets full of chain stores.
But how likely is the scheme to encourage people to shop in independent shops and deal with local traders? Will the scheme take off, or will it fizzle out? What are its downsides?
Update
The Bristol pound was duly launched on September 19 and there has been much local interest. The later videos and articles below look at reactions to the new currency and at its chances of success in driving local business.

Questions
- What are the advantages of having a local currency?
- What are the dangers in operating a local currency?
- What steps can be taken to avoid the dangers?
- Can Bristol pounds be ‘created’ by Bristol Credit Union? Could the process be inflationary?
- What market failures are there in the pattern of shops in towns and cities? To what extent is the growth of supermarkets in towns and the growth of out-of-town shopping malls a result of market failures or simply of consumer preferences?
- Are local currencies only for idealists?
- What benefits are there for shoppers in Bristol of using Bristol pounds?
With the deepening euro crisis, the slide back into recession in many developed countries and the slowing down of fast-growing developing countries, such as China and India, confidence is waning.
But just as pessimism increases, so too does uncertainty. The global economy is getting more and more difficult to forecast. So should economists give up trying to forecast? Should we rely on guesswork and hunch, or looking into crystal balls?
Bank of England representatives have been appearing before the Treasury Select Committee. And they have reiterated the consensus that things are getting more difficult to forecast. As Mervyn King said in his evidence:
There is just enormous uncertainty out there. I have no idea what is going to happen in the euro area.
And this uncertainty is making people cautious, which, in turn, damages recovery. As Dr King went on to say:
There is no doubt that with the additional uncertainty this year there’s evidence of people behaving in a very defensive way, being unwilling to invest and of course the most extreme example of that would be if we were to get to a liquidity trap where essentially the main assets people wanted to hold were claims on the central bank.
Part of the reason for the uncertainty about global growth prospects is uncertainty about what European leaders will decide about the future of the eurozone. Another is uncertainty about how people will respond to the uncertainty of others. But predicting how others will predict is very difficult as they will themselves be predicting what others will predict. This dilemma was observed by Keynes when observing how investors on the stock market behaved, all trying to predict what others will do, and is known as the Keynesian Beauty Contest dilemma (see also).
So are governments and central banks powerless to counteract the uncertainty and pessimism? Can they restore confidence and growth? Members of the Bank of England’s Monetary Policy Committee believe that further action can be taken to stimulate aggregate demand. Further quantitative easing and cuts in interest rates could help as, according to Dr King, we are not yet in a liquidity trap.

Questions
- Why is it worth economists forecasting, even if those forecasts rarely turn out to be totally accurate?
- Why is it particularly difficult in current circumstances to forecast the state of the macroeconomy 12 months hence – let alone in two or three years?
- In what ways is the global macroeconomic situation deteriorating? What can national governments do about it?
- What limits the effectiveness of government action to deal with the current situation?
- What is meant by the liquidity trap? Are we close to being in such a situation today?
- Explain what is meant by the Keynesian Beauty Contest? How is this relevant today in explaining economic uncertainty and the difficulty of forecasting the economy?
