The UK economy is suffering from a lack of aggregate demand. Low spending in real terms is preventing the economy from growing. A simple solution would seem to be to stimulate aggregate demand through fiscal policy, backed up by even looser monetary policy. But this is easier said than done and could result in undesirable consequences in the medium term.
If increased borrowing were to be used to fund increased government expenditure and/or cuts in taxes, would any resulting growth be sufficient in the medium term to reduce the public-sector deficit below the initial level through automatic fiscal stabilisers? And would the growth be sustainable? The answer to this second question depends on what happens to the supply side of the economy. Would there be an increase in aggregate supply to match the increase in aggregate demand?
This second question has led many economists to argue that we need to see a rebalancing of the economy. What is needed is an increase in investment and exports, rather than an increase in just consumer expenditure funded by private borrowing and government current expenditure funded by public borrowing.
But how will exports and investment be stimulated? As far as exports are concerned, it was hoped that the depreciation of the pound since 2008 would give UK exporters a competitive advantage. Also domestic producers would gain a competitive advantage in the UK from imports becoming more expensive. But the current account deficit has actually deteriorated. According to the EU’s AMECO database, in 2008 the current account deficit was 1% of GDP; in 2012 it was 3.7%. It would seem that UK producers are not taking sufficient advantage of the pound’s depreciation, whether for exports or import substitutes.
As far as investment is concerned, there are two major problems. The first is the ability to invest. This depends on financing and things such as available land and planning regulations. The second is the confidence to invest. With not little or no growth in consumer demand, there is little opportunity for the accelerator to work. And with forecasts of sluggish growth and austerity measures continuing for some years, there is little confidence in a resurgence in consumer demand in the future. (Click here for a PowerPoint of the above chart. Note that the 2013 plots are based on AMECO forecasts.)
So hope of a rebalancing is faint at the current time. Hence the arguments for an increase in government capital expenditure that we looked at in the last blog post (The political dynamite of calm economic reflection). The problem and the options for government are considered in the following articles.

Questions
- Draw a diagram to illustrate the effects of a successful policy to increase both aggregate demand and aggregate supply. What will determine the effect on the output gap?
- For what reasons has the UK’s current account deteriorated over the past few years while those of the USA and the eurozone have not?
- Using ONS data, find out what has happened to the UK’s balance of trade in (a) goods and (b) services over the past few years and explain your findings.
- Why are firms reluctant to invest at the moment? What policy measures could the government adopt to increase investment?
- With interest rates so low, why don’t consumers borrow and spend more, thereby aiding the recovery?
Recent figures from the ONS suggest that the UK lags well behind its competitors in terms of labour productivity. In terms of output per hour worked, Germany produces 22% more than the UK, France produces 26% more, the USA produces 27% more, the Netherlands 31% more and Ireland 43% more. The first chart illustrates some of these figures.
(Click here for a PowerPoint of this chart.)
And in the past few years the problem has been getting worse. This is shown in the second chart. This, however, is a relatively recent phenomenon. Until 2006, the gap was narrowing, but since then it has widened. (Click here for a PowerPoint of the second chart.)
What has caused this widening of the gap? Part of the problem is a historical lack of investment in the UK. Between 2005 and 2012, the UK invested on average 15.7% of GDP. The USA invested 16.5%, Germany 17.9% and France 20.1%. And part of the problem has been the cut back in private-sector investment in response to the recession (which has been deeper in the UK) and in public-sector investment as part of the government’s austerity measures.
Part of the problem has been lower levels of inward investment. Inward direct investment to the UK in 2011 was only 24 per cent of that in 2007. In France, Germany, Italy and the USA, the figures were 43, 50, 66 and 105 per cent respectively.
Part of the problem has been the size of the financial sector in the UK. This is considerably larger as a proportion of the economy than in most the UK’s major competitors. And it was this sector most hard hit by the crisis of 2007/8.
With this poor productivity performance, you might expect unemployment to have soared. In fact, the UK has one of the lowest unemployment rates of the developed countries and in recent months it has been falling while other countries have seen their unemployment rates rise.
In fact, low productivity and high employment are compatible. If people produce less than their counterparts abroad, then more people will be needed to produce the same level of output. The problem, of course, is that this only works if wages are kept down. Indeed, wages have fallen in real terms and now stand at the level of 10 years ago.
The problem of falling real wages is that this translates into a lack of demand – especially when people are trying to reduce their debts. Not only does this result in a lack of economic growth, it discourages firms from investing – and investment is one of the prime drivers of future productivity growth!
The following articles explore the problem of low productivity and its relationship with employment and with both short-term and long-term economic growth.

Investment is crucial in all sectors of the economy. With growing demand for travel abroad, airports across the world have begun implementing investment strategies to increase capacity. Airport bosses at Heathrow are currently considering a 5 year investment plan that is expected to cost £3 billion.
Although investment is certainly needed and passengers will benefit in the long run, the cost of this investment will have to be met by someone. If these plans are approved by the airport bosses, it is likely that ticket prices will be pushed upwards to pay for it. Any increase in charges will have to receive approval by the Civil Aviation Authority (CAA). The plan at the moment would see ticket prices, via landing charges, increase by £19.33 per passenger before a further rise to £27.30. The impact on customers has already been raised as a key concern.
If the investment plans proceed, Heathrow expects to see its passenger numbers increase by 2.6m over the next 5 years, despite the proposed price hikes. This would naturally increase revenue and this money would provide at least some of the funds to repay the cost of the investment.
The price rises have been described as ‘incredibly steep’ and there are concerns that they will penalize customers. Airlines, such as Virgin Atlantic have recognized the need for more investment, but are more focused on finding ways to provide it without the price rises.
However, Colin Matthews, the Heathrow Chief said:
Heathrow faces stiff competition from other European hubs and we must continue to improve the service we offer passengers and airlines.
Passengers have already seen prices rise and Heathrow’s cost base has been described by British Airways as ‘inefficient’. Despite the fact that the decision by the CAA is not expected until January 2014, speculation will undoubtedly continue until any decision is reach. The following articles consider this case.

When you look at the linked articles below, I’m sure many of you will be thinking that this is an odd choice for an economics blog! However, part of the economic relevance of ‘cyber-crime fighters’ relates to the relative skills of workers and the gap that exists between the most and least skilled workers in the UK.
Crime has always existed, but as technology has developed the types of crime committed have grown along with the complexity of them. For certain crimes, a very skilled individual is needed. With this emergence of technologically advanced crimes, those fighting crimes have also had to improve their skills and techniques. Thus crime-fighters have become more technologically advanced as well.
The problem is that the number of skilled workers able to deal with things like cyber crime has not kept pace with the demand for them and thus we have a skills gap. Usage of the Internet has continued to grow, creating more and more opportunities for cyber crime. However, the UK supply of IT and cyber-security professionals has not been able to keep pace. Therefore, we have a shortage of skilled labour in this area.
More investment into research and education is occurring, with the aim of addressing this shortage, but it is expected to take many years before supply catches up to demand. In particular, more investment is needed in the sciences and technology subjects at school to create the supply at university level. The NAO said that:
‘The current pipeline of graduates and practitioners are unable to meet demand.’
A second area of relevance to economics is the cost of cyber crime. The NAO estimated that the cost is somewhere between £18bn and £27bn per annum. However, on the other side, is there a case that crime actually benefits the macroeconomy by requiring government investment. As cyber crime has grown, so has the demand for cyber-crime fighters and this has created more jobs. With more jobs comes increased spending and the benefits of the multiplier. The following articles consider cyber crime and the impact it is having.

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.
