Economic growth is normally seen as the most important long-term macroeconomic objective. Without economic growth, so it is argued, people will be unable to achieve rising living standards. But, according to Nicholas Stern, Professor of Economics and Government at the London School of Economics, former head of the Government Economic Service, former World Bank chief economist and author of the 2006 Stern Review on the Economics of Climate Change, countries will need to reconsider making growth the goal of their societies.
Speaking to students at the People’s University of Beijing, Lord Stern warned that unless substantial cuts were made in carbon emissions, the effects of global warming would have devastating effects on people’s lives. As the Stern report stated, “Climate change will affect the basic elements of life for people around the world – access to water, food production, health, and the environment. Hundreds of millions of people could suffer hunger, water shortages and coastal flooding as the world warms.” The implications are that countries must making cutting carbon emissions a priority and must reconsider their growth strategies. In his speech he said that “Beijing should shift the economy away from heavy industry, manufacturing for exports and other high-emission activities. Instead, it should focus more on domestic consumption, service industries and low-carbon technology.”
So should countries rethink their economic objectives? Is economic growth either a necessary or sufficient condition for an increase in human welfare? Read the articles and then consider the questions below.

Questions
- Are the objectives of economic growth and tackling gobal warming necessarily incompatible?
- What would a low carbon growth strategy look like?
- What would you include in the opportunity costs of maintaining a high growth strategy compared with switching to a lower carbon, lower growth one?
- Consider whether economic growth is (a) a necessary condition; (b) a sufficient condition for a growth in the wellbeing of the human race.
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
- Do you think the evidence suggests that the outlook for the global economy is improving?
- Why will Britain probably take longer to recover from the recession than other major economies?
- What is the theory behind low interest rates helping the economic recovery?
- Which policies have the UK and other governments used to tackle this economic downturn? Would any others have been more successful?
- In what ways and for what reasons are countries economically interdependent?
With recession biting, many people are cutting back on spending. This has not been even across products, however. People have tended to shift from more luxurious products, such as foreign holidays and branded products, to holidays at home and supermarkets’ own-brand products (see Shoppers opt for supermarket brands Financial Times (4/8/09)). There has also been a decline in spending on consumer durables, such as cars, furniture and kitchen appliances.
One sector that has fared better than most, however, is the teenage market. “So far it seems teenagers have not cut back on their shopping. Teen-targeted retailers such as Primark, New Look, H&M, Asos and Hot Topic are all weathering the recession better than rivals aimed at an older demographic.” This is a quote from the first of the two linked articles below, which look at this market and its future prospects.

Questions
- How is spending on particular products during a recession related to their income elasticity of demand? How does the income elasticity of demand depend on the length of the time period under consideration?
- Why has the teenage market been less susceptible to the recession than many other markets?
- To what extent will being ‘bargain savvy’ be enough for teenagers to survive the recession without having to make substantial changes in spending patterns? Consider the concept of price elasticity of demand in your answer.
Preliminary figures for Quarter 2 UK GDP suggest that the UK economy has been declining faster than many had expected. Does this mean that the recession in the UK will be more prolonged, or can we expect a return to growth by the end of the year? How much does the outcome depend on policy decisions taken now and what should be done in terms of quantitative easing and other policy measures?
The answers to these questions depend to some extent on the reliability of the figures, which, after all, are only preliminary estimates. Past estimates have tended to understate the level of output and growth, but could the latest estimates understate the depth of the recession? The following articles look at the figures and their implications for policy. The two articles from The Economist look at the global context.

Questions
- What factors will determine whether the UK economy starts to growth again by the end of 2009?
- Plot the quarterly growth rate of GDP from 2007 Q1. Plot two lines on the same graph: one from the 2008 Q4 estimates and one from the 2009 Q2 estimates (see last two links above). How would you explain the discrepancies between the figures?
- What policy measures would you recommend to the Bank of England and the government in the light of the GDP estimates?
- ’The deeper and longer the recession, the more will potential (as well as actual) output fall.’ Do you agree with this statement? Explain your answer.
- Referring to the two Economist articles, what conditions are necessary for sustained long-term economic growth?
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.
