BP has just published its latest projection of energy trends – its Energy Outlook 2030. According to the press release:

World energy growth over the next twenty years is expected to be dominated by emerging economies such as China, India, Russia and Brazil while improvements in energy efficiency measures are set to accelerate.

The following podcast from the Financial Times features a discussion of the report and the factors affecting oil prices and their relationship to economic growth

Questions

  1. What are the most powerful driving forces behind the demand for energy?
  2. Why does the report forecast virtually no increase in energy demand in developed countries? What assumptions are made about growth rates in OECD and non-OECD countries?
  3. What factors would lead to a substitution of sustainable energy sources for fossil fuels? What would detrmine the size of such substitution?
  4. What is the role of the price elasticity of demand for and supply of oil and the income elasticity of demand for oil in determining oil consumption in different parts of the world?
  5. Why may high energy prices not necessarily mean ‘doom’?

The recession caused a large rise in unemployment in many countries. In the USA the rise has been particularly steep, where unemployment now stands at 14.5 million, or 9.8% of the labour force. Unemployment has continued to rise despite renewed growth in the US economy, where the latest annual real GDP growth is 2.6% (measured in Q3 2010). The rise in unemployment has been blamed on ‘sticky wages’ – i.e. the reluctance of wage rates to fall.

But are wages genuinely sticky as far as the average worker is concerned? They may be in many specific jobs with specific employers, but many workers made redundant then find work in different jobs at lower rates of pay. For them, their wage has fallen, even if particular jobs are paying the same as before.

So what are the consequences of this? Does the willingness of workers to accept lower paid jobs mean that the labour market is flexible and that people will thus price themselves into work? If so, why is employment still rising? Or does a reduction in real wages for many people dampen spending and hence aggregate demand, thereby reducing the demand for labour? If so, why is GDP rising?

The following articles look at the apparent stickiness of wages and the implications for the labour market and the macroeconomy.

Questions

  1. Why might nominal wages be sticky downwards in specific jobs in specific companies?
  2. Why might nominal average wages in the economy not be sticky downwards?
  3. Why is unemployment rising in the USA?
  4. Why might there be a problem of hysteresis in the USA that provides an explanation of the reluctance of unemployment to fall?
  5. Why might a fall in wages end up being contractionary?
  6. What lessons can be learned from the Great Depression about cures for unemployment?
  7. How might unemployment be brought down in the USA?
  8. Why may making wages somewhat more flexible, as opposed to perfectly flexible, not be a good thing?

Bank rate in the UK has been at the historically low level of 0.5% since March 2009 and the MPC decision on 13 January was to leave the rate unchanged (see also). But inflation has been well above the Bank of England’s target of 2% since December 2009 and it could well rise further as international commodity prices are soaring. Some economists are thus arguing that Bank rate should rise. This is crucial, they say, to dampen inflationary expectations.

Other economists, however, argue that aggregate demand is likely to remain depressed and that the economy is operating with a large negative output gap. What is more, house prices are falling, as are real wages (see Bosses gain – workers’ pain)

In the following extract from BBC Radio 4’s Today Programme, two economists, Charles Goodhart and Willem Buiter, both former members of the MPC, debate the issue.

Monetary Policy Committee Decisions Bank of England

Questions

  1. What are the arguments for a rise in Bank rate at the current time?
  2. What are the arguments against a rise in Bank rate at the current time?
  3. What information would you require to decide which of the arguments was the more powerful?
  4. Why is it difficult to decide the size of the output gap?
  5. To what extent do the arguments for and against a rise in Bank rate depend on the factors determining expectations, and what expectations are important here?
  6. To what extent are exchange rates relevant to the effectiveness of interest rate policy?

Two reports on business confidence in the UK have just been published. The first, by Lloyds TSB Commercial, is its twice-yearly Business in Britain Report. The second is the Quarterly Economic Survey by the British Chambers of Commerce. Both reports paint a mixed picture about business confidence.

First the good news: the export sector is booming. Demand for exports is being boosted by (a) the depreciation of the pound, with the sterling exchange rate index some 20% lower now compared with the start of 2008 and (b) rapid economic growth in China, India and many other developing countries. Not surprisingly many exporting companies are looking to a bright future and are willing to invest.

Now the bad news. Domestic demand for many products is declining, especially services. This is not surprising given the rise in VAT, cuts in public spending and consumers cautious about their employment and income prospects in the coming year. With rapid cost-push inflation from higher oil and commodity prices, real incomes are set to fall and with it the level of real consumer demand (see Bosses gain – workers’ pain).

So where is the economy heading? The mixed picture painted by the two reports mean that the economy is likely to remain on the cusp. But with the export sector being much smaller than the domestic market, worries are likely to persist that economic growth may well slow significantly and the economy might return to recession. The main hope is that the restocking and replacement investment that follow a recession may be enough to provide just enough extra demand to avoid the ‘double dip’.

  3. Why is the manufacturing sector as a whole experiencing relatively strong economic growth?
  4. If the service sector shrank by x% and the manufacturing sector grew by x%, what would be likely to happen to the rate of economic growth in the economy? What else would you need to know to establish the precise rate of economic growth?
  5. The BCC said both the government and the Bank of England must “act forcefully to support growth”. What measures would this include?

Here’s an interesting example of oligopoly – one you probably haven’t considered before. It’s the art market. And it’s not just one market, but a whole pyramid of markets. At the bottom are the ‘yearning masses’ of penny-poor artists, from students to those struggling to make a living from their art, with studios in their attic, garden shed or kitchen table. At the top of the pyramid are those very few artists that can earn fantastic sums of money by selling to collectors or top galleries. Then there are all the layers of markets in between, where artists can earn everything from a modest to a reasonable income.

The pyramid is itself depicted as a work of art, which you can see in the linked article below. It’s worth studying this piece of art carefully as well as reading the article.

Questions

  1. Identify the increasing barriers to entry as you work up the art market pyramid.
  2. Are there any other market imperfections in the art market that you can identify from the diagram?
  3. What are the key differences between the ‘primary market, tier 1’, the ‘primary market, tier 2’ and ‘the secondary market’?
  4. Are artists ‘rational maximisers’? If so, what is it they are trying to maximise? If not, why not?
  5. How would you set about determining the ‘worth’ of a piece of art? How do possible future value of a piece of art determine its present value?
