From October 2007 to March 2009, stock markets around the world fell massively. In the UK, the FTSE 100 fell from a peak of 6752 on 15 October 2007 to a trough of 3461 on 9 March 2009 (a fall of 49 per cent). By the end of August 2009 it had reached 4944 (a rise since March of 43 per cent). Does this mean that the March value represented an over-correction downwards? Did the subsequent rise represent an over-correction upwards? Are stock markets about to plummet? The following two articles reflect on the past and look into the future!

Questions

  1. What is meant by the ‘efficient (capital) market hypothesis’?
  2. If stock markets are overvalued, does this mean that they are inefficient?
  3. Why might (a) stock markets plummet in the near future; (b) carry on rising? Why don’t the ‘experts’ know which will happen?
  4. Explain why markets may over-shoot their long-term equilibrium value?

This podcast is from BBC Radio 4’s Today Programme. It consists of an interview with James Berresford, chief executive of VisitEngland, and Tracy Corrigan, of the Daily Telegraph on the topic of ‘staycations’ – a term used to refer to people holidaying at home rather than going abroad. Staycations are up, but why is this the case; how much have people switched; and is it really a cheaper option?

Questions

  1. What are the determinants of demand for staycations? How have these impacted on the demand for staycations in the UK in summer 2009?
  2. How are the (a) price; (b) income and (c) cross-price elasticities of demand for staycations relevant in determining the demand for staycations?
  3. Why is imperfect information an important problem in making a decision about where to take a holiday and how do risk attitudes affect the decision?
  4. Why has unemployment risen more than the UK national average in many seaside towns?

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’?

Tea prices have soared in recent months. Explanations can be found on both the demand and supply side. But while this might be bad news for tea drinkers, the news is more mixed for tea growers. So just what are the causes and consequences of the price rises? The following linked articles look at the issues.

Questions

  1. Identify the factors on the demand and supply sides that have led to the rise in tea prices. Draw a diagram to illustrate your answer.
  2. Under what circumstances will farmers benefit from a rise in tea prices? What is the relevance of the market price elasticity of demand to your explanation?
  3. If the price of tea in the shops rises, will this necessarily mean a rise in the price to tea growers and in the wages of workers on tea plantations? Explain using concepts of competition and market power.
  4. What will be the effect of using more land for growing tea on (a) the price of tea and (b) the incomes of tea growers?

Many primary commodity prices have fallen during the recession, but have recovered somewhat as the recession has bottomed out and hopes of a recovery have grown.
