Both business and consumer confidence are affected by the state of the economy. A recession, or even a slowdown in the economy, will make people worried for their jobs and future incomes and hence cut back on spending and either save more or reduce their debts. Similarly firms are likely to cut back on investment if they are pessimistic about the future. But both consumer demand and investment are components of aggregate demand. A cut in aggregate demand will drive the economy further into recession and cause even greater pessimism. In other words, there is a feedback loop. Recession causes pessimism and hence a fall in aggregate demand, which, in turn, worsens the recession.

A similar process of feedback occurs in times of optimism. If the economy recovers, or is thought to be about to do so, the resulting optimism will cause people and firms to spend more. This rise in aggregate demand will help the process of recovery (see Accelerating the recession and Animal Spirits).

The following article by Robert Shiller, co-author of Animal Spirits: How Human Psychology Drives the Economy, and Why It Matters for Global Capitalism, looks at the swing from pessimism to optimism over the past few months.

Questions

  1. Explain why “confidence has rebounded so quickly in so many places” in recent weeks.
  2. Is Robert Shiller’s explanation of feedback loops consistent with the accelerator theory?
  3. In what circumstances do business and consumer psychology result in destabilising speculation and what causes turning points in the process? Why may such turning points be difficult to predict?
  4. Examine the monthly Economic Sentiment Indicator (ESI) for the UK from the ‘Business and Consumer Surveys: Time Series’ link above. You will need to refer to the final column in the Excel ESI Monthly worksheet (Column GV). Chart the movements in this indicator over the past three years. Also chart the quarterly growth in UK GDP over the same time period. You can find data from Economic and Labour Market Review (ONS), Data tables, Table 1.01, Column YBEZ. Is ESI a leading or a lagging indicator of GDP?
  5. What implications does Shiller’s analysis have for the management of the economy?
  6. Why may stock market movements not be a ‘random walk’?

Investment in the UK in quarter 2 2009 fell by the largest amount since records began in 1965. Why has this happened and what does it tell us about the determinants of investment? Does it mean that businesses are short sighted or risk averse, or does the lack of investment reflect a lack of finance in the aftermath of the credit crunch. The following articles look at the data and what they signify.

Questions

  1. Chart the quarterly percentage change in business investment and quarterly economic growth on the same diagram. (See the second ONS link above and also Gross domestic product: Preliminary estimate – 2nd Quarter 2009 and GDP growth (revised estimate).
  2. Why has investment fallen so dramatically?
  3. Is the pattern of investment and GDP growth consistent with the accelerator theory?
  4. To what extent is investment a leading or a lagging indicator of economic activity?

With the world economy in recession, major exporting countries are suffering more than many, especially exporters of high-quality manufactured products, many of which have a high income elasticity of demand. Germany, the world’s largest exporter, has been particularly hard hit. In the year to April 2009, the value of German exports fell by 28.7 per cent. The following articles look at the data and some of the explanations.

Questions

  1. Why have German exports fallen considerably more than German GDP? How can the accelerator theory help to explain the fall in German exports?
  2. If economic sentiment recovers in Germany, how will this affect (a) aggregate demand; (b) imports; (c) exports?
  3. Find out what has happened to the euro exchange rate index and assess whether movements in the euro have contributed to Germany’s export performance (see for example the Bank of England Statistical Interactive Database).
