As we saw in Part 1 of this blog, oil prices have fallen by some 46% in the past five months. In that blog we looked at the implications for fuel prices. Here we look at the broader implications for the global economy? Is it good or bad news – or both?

First we’ll look at the oil-importing countries. To some extent the lower oil price is a reflection of weak global demand as many countries still struggle to recover from recession. If the lower price boosts demand, this may then cause the oil price to rise again. At first sight, this might seem merely to return the world economy to the position before the oil price started falling: a leftward shift in the demand for oil curve, followed by a rightward shift back to where it was. However, the boost to demand in the short term may act as a ‘pump primer’. The higher aggregate demand may result in a multiplier effect and cause a sustained increase in output, especially if it stimulates a rise in investment through rising confidence and the accelerator, and thereby increases capacity and hence potential GDP.

But the fall in the oil price is only partly the result of weak demand. It is mainly the result of increased supply as new sources of oil come on stream, and especially shale oil from the USA. Given that OPEC has stated that it will not cut its production, even if the crude price falls to $40 per barrel, the effect has been a shift in the oil supply curve to the right that will remain for some time.

So even if the leftward shift in demand is soon reversed so that there is then some rise in oil prices again, it is unlikely that prices will rise back to where they were. Perhaps, as the diagram illustrates, the price will rise to around $70 per barrel. It could be higher if world demand grows very rapidly, or if some sources of supply go off stream because at such prices they are unprofitable.

The effect on oil exporting countries has been negative. The most extreme case is Russia, where for each $10 fall in the price of oil, its growth rate falls by around 1.4 percentage points (see). Although the overall effect on global growth is still likely to be positive, the lower oil price could lead to a significant cut in investment in new oil wells. North sea producers are predicting a substantial cut in investment. Even shale oil producers in the USA, where the marginal cost of extracting oil from existing sources is only around $10 to £20 per barrel, need a price of around $70 or more to make investment in new sources profitable. What is more, typical shale wells have a life of only two or three years and so lack of investment would relatively quickly lead to shale oil production drying up.

The implication of this is that although there has been a rightward shift in the short-run supply curve, if price remains low the curve could shift back again, meaning that the long-run supply curve is much more elastic. This could push prices back up towards $100 if global demand continues to expand.

This can be illustrated in the diagram. The starting point is mid-2014. Global demand and supply are D1 and S1; price is $112 per barrel and output is Q1. Demand now shifts to the left and supply to the right to D2 and S2 respectively. Price falls to $60 per barrel and, given the bigger shift in supply than demand, output rises to Q2. At $60 per barrel, however, output of Q2 cannot be sustained. Thus at $60, long-run supply (shown by SL) is only Q4.

But assuming the global economy grows over the coming months, demand shifts to the right: say, to D3. Assume that it pushes price up to $100 per barrel. This gives a short-run output of Q3, but at that price it is likely that supply will be sustainable in the long run as it makes investment sufficiently profitable. Thus curve D3 intersects with both S2 and SL at this price and quantity.

The articles below look at the gainers and losers and at the longer-term effects.

I found this interesting article on the BBC News website about three students in Nigeria who have created an online job search company. Only five years later, this company now is valued in the millions and employs over 100 people.

The article below contains some interesting insights into the Nigerian job market and the key to success for this company. In particular, they note the effect of the multiplier through job creation and how this has been used to benefit the wider economy. This is particularly pertinent given the severe unemployment problem that has affected this African economy. It has helped 35,000 people to find jobs in the past two years.

  1. What are the main causes of the unemployment problem in Nigeria?
  2. The company itself employs hundreds of people, but indirect employment effects have also occurred. How has this happened?
  3. How important are entrepreneurs in African countries as a means of helping their development?

While much of the UK is struggling to recover from recession, the London economy is growing strongly. This is reflected in strong investment, a growth in jobs and rapidly rising house prices.

There are considerable external economies of scale for businesses locating in London. There is a pool of trained labour and complementary companies providing inputs and services are located in close proximity. Firms create positive externalities to the benefit of other firms in the same industry or allied industries.

London is a magnet for entrepreneurs and highly qualified people. Innovative ideas and business opportunities flow from both business dealings and social interactions. As Boris Johnson says in the podcast, “It’s like a cyclotron on bright people… People who meet each other and spark off each other, and that’s when you get the explosion of innovation.”

Then there is a regional multiplier effect. As the London economy grows, so people move to London, thereby increasing consumption and stimulating further production and further employment. Firms may choose to relocate to London to take advantage of its buoyant economy. There is also an accelerator effect as a booming London encourages increased investment in the capital, further stimulating economic growth.

But the movement of labour and capital to London can dampen recovery in other parts of the economy and create a growing divide between London and other parts of the UK, such as the north of England.

The podcast examines ‘agglomeration‘ in London and how company success breeds success of other companies. It also looks at some of the downsides.

HS2 has been a controversial topic for some time now. Between the disruption it would cause to countless neighbourhoods and the protests that have emerged and the debate about the cost effectiveness of the project, it’s been in the news a fair amount. The transport network in the UK needs improving, not only for businesses located here, but also to encourage more investment into the country. HS2 is one of the solutions offered.

The latest estimate for the cost of HS2 is over £40 billion. However, many suggest that the benefits HS2 will bring do not cover the full costs. Furthermore, as noted above, other concerns include the disruption that it will bring to countless households who will be living along the proposed routes. Cost benefit analysis have been carried out to determine the viability of the project, but they are invariably difficult to do. As they involve determining all of the private and social costs and benefits and putting a monetary estimate onto them, there will inevitably be factors that are over-looked, under-estimated or over-estimated. The suggestions here are that the costs have been under-estimated and the benefits over-estimated.

In September, KPMG produced a report that estimated the overall benefit to the UK economy would be a boost to growth of 0.8%, which would benefit many businesses and communities. The British Chambers of Commerce said:

Business communities in dozens of cities and towns, from many parts of the UK, remain strongly supportive of HS2.

The railway network is also approaching full capacity and this is one of the reasons why HS2 has been proposed. A government source said:

We need to do something because our railways are nearly full, but the alternative to HS2 is a patch and mend job that would cause 14 years of gridlock, hellish journeys and rail replacement buses … The three main routes to the north would be crippled and the economy would be damaged.

However, this report has faced criticism, in particular because it ignored a variety of supply-side constraints and because they argue it would be more effective to simply update the existing network. However, a new government-commissioned report has suggested that this alternative to HS2 would involve 14 years of weekend route closures and much longer journey times. However, those in favour of updating existing routes have said that this new report commissioned by the government is ‘a complete fabrication’. Hilary Wharf of the HS2 Action Alliance commented:

This government-funded report is a complete fabrication. The main alternative to HS2 involves longer trains and reduced first-class capacity to provide more standard class seats…No work is required at Euston to deliver the necessary capacity increase. Work is only required at three locations on the WCML [West Coast Main Line], and this is comparable to the work being carried out on the route at present.

The debate regarding HS2 will continue for the time being and it is just another area that is fuelling the political playing field. Whatever is done, the rail network certainly requires investment, whether it is through HS2 or upgrades to the existing routes. The following reports and articles consider the latest developments and controversy regarding HS2.

In a News Item of 1 October, Over the Cliff, we looked at the passing of the deadline that same day for Congress to agree a budget. We also looked at the looming deadline for Congress to agree a new higher ceiling for Federal Government debt, currently standing at $16.699 trillion. Without an agreement to raise the limit, the government will start becoming unable to pay some of its bills from around 17 October.

One week on and no agreement has been reached on either a budget or a higher debt ceiling.

Failure to agree on a budget has led to the ‘shut-down’ of government. Only essential services are being maintained; the rest are no longer functioning and workers have been sent home on ‘unpaid leave’. This has led to considerable hardship for many in the USA. It has had little effect, however, on the rest of the world, except for tourists to the USA being unable to visit various national parks and monuments.

Failure to raise the debt ceiling, however, could have profound consequences for the rest of the world. It could have large and adverse effects of global growth, global trade, global investment and global financial markets. The articles below explore some of these consequences.

  3. How would a continuation of the partial government shut-down impact on the US private sector?
  4. What multiplier effects on the rest of the world are likely to arise from a cut in US government expenditure or a rise in taxes? What determines the size of these multiplier effects?
  5. Explain the likely effect of the current crisis on the exchange rate of the dollar into other currencies.
