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 east coast mainline from London to Edinburgh is a ‘premium route’. This means that it is one of the lines in the UK that is profitable. When the franchises come up for renewal on such lines, potential operators bid to pay the government for the franchise. National Express won the eight-year franchise in 2007 for a total of £1.4 billion, paid in annual rising instalments.

Although the east coast mainline is still profitable, the recession has meant that passenger numbers have been insufficient for National Express to make its annual payments to the Department for Transport and still be left with a profit. As a result, the government will take the franchise into public ownership later this year. This specially created nationalised company will then operate trains on the route until a new franchise is awarded to a private company at the end of 2010.

So why has this proved necessary? Is it all down do the depth of the recession? Or was the £1.4 billion cost of the franchise unrealistically expensive? Would the answer be for National Express to merge with another operator, such as the First Group? Or should the government be prepared to waive, or at least reduce, the franchise payments until passenger numbers are growing fast enough? Or is it time to rethink the whole UK model of rail privatisation and perhaps return to a nationalised rail system? The articles below consider the issues.

Questions

  1. Consider the relative merits of temporary nationalisation of the east coast mainline services with providing temporary support for National Express.
  2. Should profitable rail franchises be awarded to the highest bidder? Similarly, should loss-making franchises be awarded to companies bidding for the lowest subsidy?
  3. Discuss the arguments for and against a complete re-nationalisation of the railways.
  4. With reference to the final article above, explain what is meant by a Special Purpose Vehicle and whether it was an appropriate means for National Express to fund its £1.4 billion franchise. What dangers are associated with this and other new forms of ‘no-risk capitalism’? Is there a ‘moral hazard’ in this form of capitalism?

In an attempt to revive the fortunes of the French restaurant industry, where demand has been flagging during the recession, the French government slashed VAT on restaurant meals from the standard 19.6 per cent to 5.5 per cent from 1 July 2009. But how much of the tax cut will be passed on to customers; will there be an equal percentage price cut for all items on any particular restaurant’s menu; what will be the impact on consumer demand; and what will be the impact on the government’s tax revenue? The following articles look at the issues.

Restaurants’ VAT cut from today The Connexion (1/7/09)
French diners feast on benefits after generous cut in restaurant tax Guardian (1/7/09)
France Whacks Food Tax The Wall Street Journal (2/7/09)

Questions

  1. Using a demand and supply diagram, demonstrate the effect of a VAT cut on the price of a particular item on a menu.
  2. Examine the factors that will determine (a) the average percentage price cut made by a particular restaurant and (b) the percentage price cut on a particular item on the menu.
  3. “One third of the VAT cut is supposed to help pay for price cuts with another third going to increase staffing. The final third should go to improving restaurant facilities.” Consider the likelihood of this occurring.
  4. “The measure will cost the French state 2.38 billion euros a year.” How, do you think, this figure was arrived at and how accurate is the figure likely to be? Are there any circumstance under which the tax cut could increase tax revenues?

“As the global economic crisis forces everyone to downsize, the self-sufficient worker once again has a chance, whether as a farmer growing vegetables for local consumption or as an open-source software developer who makes a living in his basement office.” So argues the first article linked to below. Does this mean that economies of scale are over-exaggerated? Should developing countries provide more support to small-scale production as a growth and development strategy? And does small-scale production provide benefits beyond those of production and profit? Does it meet broader human and social needs? The articles explore the issues: the first two in the context of the developed world and the other four in the context of developing countries.

Questions

  1. What are the benefits of ‘a return to yeomanry’ (a) to the individuals themselves; (b) to society and the environment?
  2. Why might it prove a risky strategy for those embarking on small-scale production? How could governments help to reduce the risks for the producers? Should they?
  3. Discuss whether fostering small-scale farming is an appropriate development strategy for developing countries. What specific policy measures should governments adopt?
  4. Is land reform (a) a necessary condition; (b) a sufficient condition if small-scale farming is to flourish in developing countries? What pitfalls are there from a policy of land reform?

The early part of the current recession, dating from April 2008, had much in common with the Great Depression dating from June 1929. But the Great Depression lasted three years. So does this grim prospect await the world this time round? Or have we learned the lessons of the past and will the policies of giving economies a large fiscal stimulus, combined with bank rescues and quantitative easing, help to pull the world out of recession this year? The following articles look at the issues.
