The pound has been rising against the US dollar recently. And as the dollar has fallen, so the prices of various commodities, such as gold and silver, have been rising. So what are the reasons for these currency and commodity price movements? The simple answer is that they merely reflect changes in demand and supply. But why have demand and supply been changing? Are there changes in the underlying economic fundamentals, or do they largely reflect speculation in times of uncertainty and resulting market overcorrection? The following articles address these questions.

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?

  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?

The recession of the past few months has taken its toll on organic farmers. Until recently, the industry was booming as consumers switched to products perceived as greener, healthier and more ethically produced. Now, as many consumers are feeling the pinch, they are switching to cheaper foodstuffs. The resulting decline in demand for organic food has turned profit into loss for many organic farmers. According to the first of the linked articles below, at least two organic farmers are leaving the movement each week.

But what will happen as the economy recovers and people start turning back to organic products? Given that it takes some two years to convert to organic standards, there could be supply shortages next year.

Questions

  1. How close to perfect competition is the market for organic foods?
  2. What determines whether an organic farmer should continue in the market even though a loss is being made?
  3. What can you conclude about the income and price elasticities of demand for organic produce and the cross-price elasticity of demand for organic food with eating out?
  4. What is likely to happen to the market for organic food over the next two years?

The European Commission is concerned that the economic downturn may have put the livelihoods of dairy farmers at risk. To try to prevent any problems for farmers, the Commission has re-introduced export subsidies for dairy products. The last time subsidies were paid to dairy farmers was June 2007 and the EU insists that the payment will meet World Trade Organisation (WTO) rules.

  4. Discuss the likely reaction of other countries to the EU’s payment of export subsidies to dairy farmers.

Somali pirates have been much in the news recently with their high profile captures of oil tankers and other ships. The impact on shipping in the area is clear and this has disrupted trade in the region, but an unforeseen impact has been on the total worldwide catch of tuna. The Indian Ocean is one of the richest sources of tuna in the world and the pirate activity has led to a fall of around 30% in the total tuna catch.
