Oil affects our everyday lives. Whether it’s to heat your house, to run your car or to work out production costs, the price of oil is important. Commodity prices are determined by the interaction of demand and supply and oil prices are no different. As demand and supply for products and for oil itself change, so will the price of oil. However, any changes in the price of this valuable commodity will also have effects on macroeconomic variables, such as inflation. From a high of $147 (£90) per barrel in July 2008, it fell to $30 by the end of the year. But since then it doubled to reach $60 by May and has been around the $70 mark since.

How have these fluctuations affected the economy? Should more be invested in extraction? Extracting oil is an expensive process and requires huge investment, which is problematic given the current recession and various funding issues. The following articles consider this problem, as well as the impact it is likely to have on our economic recovery.

All nations are interdependent and few have escaped the recent economic turmoil that began with the collapse of the sub-prime mortgage market in America. Businesses have gone under; interest rates have been cut and then cut again; profits have fallen; unemployment has risen and expectations have remained gloomy.

But, what’s the latest? How is the British economy faring and what about the rest of the world? Some sources suggest that we are already in a recovery, whereas others suggest that the current downturn is not yet over. House prices recovered somewhat in July, but various sources suggest that they experienced their biggest fall in August. The following articles look at recent economic developments.

Questions

  1. Do you think the evidence suggests that the outlook for the global economy is improving?
  2. Why will Britain probably take longer to recover from the recession than other major economies?
  3. What is the theory behind low interest rates helping the economic recovery?
  4. Which policies have the UK and other governments used to tackle this economic downturn? Would any others have been more successful?
  5. In what ways and for what reasons are countries economically interdependent?

The output gap is defined as ‘the difference between actual and potential output.’ When actual output exceeds potential output, the gap is positive. When actual output is less than potential output, the gap is negative. The size of the output gap traces the course of the business cycle. In the current recession, the output gap is negative in all major economies. The worry in recent months has been that a persistent large negative gap could lead to a downward deflationary spiral. Evidence is emerging, however, that the recession may be bottoming out and the danger of deflation easing. But just how big is the current negative output gap? As the article below from The Economist states, “Estimating how big the output gap is, and how much of a deflationary threat it still poses, is not easy.”

So how is the output gap measured in practice? How do we measure ‘potential output’? The two articles consider this issue of measurement and the relationship between the output gap and the rate of inflation. The last two links are to data sources giving estimates of the output gap. The first is from the European Commission and the second is from the OECD. As you will see, there are differences in their estimates.

Questions

  1. Why is it difficult to measure potential output? (See both The Economist article and Box 1.3.2 from the European Economy: Economic Forecast, Spring 2009.)
  2. What is meant by the ‘NAIRU’? Why may it have risen during the recession? How would you set about estimating the value of the NAIRU?
  3. How might you infer the size of the output gap from the behaviour of inflation?
  4. Plot the output gap for two countries of your choice using data from both the European Economy and the OECD Economic Outlook for the years 2004 to 2010. Discuss the differences between (a) the two plots for each country and (b) the two countries.

The global economy has been in a recession since December 2007, but have we now passed the worst of it? Whilst companies are still going bankrupt, unemployment is still rising, the housing market is still looking pretty gloomy and government debt surely can’t go up anymore, there are indications that we’ve reached the bottom of the recession. There are murmurs that the economy may start to recover towards of the end of the year.

But, of course, economics wouldn’t be economics if there wasn’t considerable disagreement. Many still believe that the worst is yet to come. According to the OECD, the recession is ‘near the bottom’. Yet, output in the UK is still set to decline by 4.3% in 2009, and by 2010 the budget deficit is predicted to have grown to 14%. Unemployment is at its highest since November 1996, but US consumer confidence is said to be rising and the pound is climbing. Read these articles and make up your mind about the state of the UK and global economy!!

Questions

  1. What are the typical characteristics of a recession? Do the current statistics of the four main macroeconomic objectives fit in with what economic theory tells us?
  2. Which policies would governments normally implement to get a economy into the expansionary/recovery phase of the business cycle and how do they work?
  3. Why is consumer confidence so key to economic recovery?
  4. What type of banking regulation is needed to prevent a similar crisis happening again?
  5. Movements in the housing market are often seen as indicators of the state of the economy. Why is this?

The term hyperinflation is almost an understatement when it comes to describing the level of inflation in Zimbabwe. In July 2008, inflation was estimated to be 231 million per cent. In January 2009, two estimates were made: one of 5 sextillion per cent (5 and 21 zeros); the other of 6.5 quindecillion novemdecillion per cent (65 and 107 zeros). These figures are simply mind-boggling for most people living in low-inflation economies.

Commentators say that prices can double in a single day and this can render banknotes useless very quickly. In fact, local banknotes are scarcely used as people turn to overseas currencies that offer more stability. Recognising this, in late January 2009 the government officially allowed foreign currencies to be used in Zimbabwe as well as the Zimbabwe dollar.

In an attempt to stabilise the currency the Zimbabwean central bank on more than one occasion has tried dropping several zeros from the currency. But this has had little effect and in January 2009 a new series of banknotes was issued, including a Z$100 trillion note. This is unlikely to be the last issue though, but what comes after a trillion?

Questions

  1. Define the term hyperinflation.
  2. Analyse the main causes of hyperinflation.
  3. Discuss policies that the Zimbabwean government could adopt to try to reduce the level of inflation in the economy.
  4. Assess the impact of hyperinflation on the other major macro-economic targets.
  5. Research another instance of hyperinflation and write a brief summary of the cause(s) and the solution(s). You may find the Wikipedia entry on hyperinflation a good starting point.
