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?

The traditional macroeconomic issues are well-known: unemployment, inflation, economic growth and the balance of payments. However, the environment, and specifically climate change, have become increasingly important objectives for the global economy. Over recent months, many countries have announced new policies and measures to tackle climate change.

The costs of not tackling climate change are well-documented, but what about the costs of actually tackling it? Why is a changing climate receiving such attention and what are the economics behind this problem? The articles below consider this important issue.

  2. Apart from imposing limits on emissions, what other interventionist policies could be used? What are the advantages and disadvantages of each of them?
  3. According to the EU, the cost of tackling climate change is very high. So, why are we doing it? See if you can carry out a cost-benefit analysis!
  4. Why is climate change presenting a problem for insurance companies? Can it be overcome?

Many industries are struggling in the current climate and, in particular, car sales have been at an all time low. General Motors was the biggest car company in the world, but recently we have seen them becoming the biggest industrial bankruptcy, which will have consequences for many car manufacturers around the world. UK car sales were 25% lower in May 2009 than at the same time last year and Chrysler will sell most of their assets to Fiat when they form a strategic alliance in a bid to help them exit bankruptcy protection.

The troubles of the carmakers have passed up the production chain to automotive suppliers, component manufacturers and engineering firms, and down the chain to the dealerships at a time when consumer confidence has taken a knock. The following articles look at some of the recent developments in the car industry and consider their likely economic impact.

Questions

  1. What is a strategic alliance and how should it help Chrysler?
  2. What are some of the methods that governments have used to help stimulate the car industry? Consider their advantages and disadvantages.
  3. Think about the consequences beyond the car industry of the decline of General Motors. Who is likely to suffer? Will there be any winners?
  4. General Motors was established in 1908. How were they able to expand so quickly and what do you think are the main reasons for their current decline?
  5. The article in The Economist suggests that, despite the current problems in the car industry and the global recession, selling cars will never really be a problem. What do you think are the reasons for this?

The following link is to a video charting the growth of China and the UK over the past 200 years and projecting forward to 2014. The video is from Gapminder, a site that allows you to compare countries’ performance in terms of a large range of economic and social indicators.

The introduction to this video states, “200 years ago, United Kingdom was a leading nation of the world – both in regard to health and economy. In this video, Hans Rosling details UK’s 200-year journey, to present time, and also shows that China, in the coming five years, will narrow the gap to UK faster than ever.”

Crisis narrows China–UK gap Hans Rosling, Gapminder (2/6/09)

Questions

  1. Why has the gap in GDP per head narrowed between the China and the UK?
  2. Why is the gap likely to narrow further over the next five years?
  3. Identify the factors that will determine how much the gap is likely to narrow in this period.

The following articles look at a recently published book by George Akerlof of the University of California, Berkeley, and Robert Shiller of Yale. They examine the role of what Keynes called ‘animal spirits’ and is the title of the book.

The motivation to make economic decisions (to buy, to sell, to invest, etc) may not be ‘rational’ in the sense of carefully weighing up marginal costs and marginal benefits. Rather it can be one of over-optimism in good times or over-pessimism in bad times. Just as individuals have ‘mood swings’, so there can be collective mood swings too. After all, confidence, or lack of it, is contagious. This motivation that drives people to action is what is meant by animal spirits.

But are animal spirits a blessing to be nurtured or a curse to be reined in? Should governments seek to constrain them?

Questions

  1. Describe what is meant by ‘animal spirits’ and their effects on human behaviour.
  2. Why may animal spirits make economies less stable?
  3. How may animal spirits help to explain exchange rate overshooting?
  4. Discuss whether governments should seek to constrain animal spirits and make people more ‘rational’? Also consider what methods governments could/should use to do this?
