Gold prices have been soaring in recent months. In fact, such is the demand for the precious metal that Harrods has just started selling gold bars. “The Knightsbridge department store yesterday began selling bars of pure Swiss gold bullion as part of a range that is being displayed in a miniature vault on the lower ground floor” (see eighth link below).

In November 2008, gold was trading at around $750 per ounce; by October 2009, the price had reached $1080 per ounce. Why has this happened? Will the trend continue? What does it signify about the world economy – both its current and likely future state? The following articles look at the causes and effects of this new ‘golden age’.

Questions

  1. Use a demand and supply diagram to illustrate the change in the price of gold between November 2008 and October 2009. Does the explanation lie largely of the demand or the supply side? Use the concepts of price elasticity of demand and supply to explain the size of the price change for any given shift in demand or supply.
  2. How is the price of gold related to the strength of the US dollar?
  3. Explain whether gold is a commodity or a currency (or both).
  4. What is meant by the ‘head and shoulders pattern’ in the price of gold? Is the use of ‘patterns’ a good way of predicting future prices? Give reasons why it may or may not be.

The housing market has been very volatile over the past year or so. House prices crashed, but then appeared to stabilise. Since then, however, different sources have given very different opinions and predictions about future movements. According to Nationwide Building Society, house prices have increased by an average of £53 a day during September, but others suggest that they remain stable and that they may fall again in 2010.

Not only are house prices important to those buying and selling, but the state of the housing market is also crucial for the recovery of the economy. For example, the construction industry has suffered over the past year and, as of the 2nd October 2009, unemployment in this sector stood at 17.1%. As more and more workers lose their jobs, their disposable income falls and hence demand in the economy is affected. With the possibility of an election debate between the party leaders, many will be waiting to see what their strategies are to revitalise a struggling economy.

Questions

  1. Why are recent movements in the housing market going to be a problem for first-time buyers?
  2. The ‘Stamp duty holiday’ will soon come to an end. What do you think will be the impact on the demand for and supply of houses and hence equilibrium prices over the next 6 months?
  3. One of the reasons why house prices have stabilised is a lack of supply. How does this affect equilibrium prices?
  4. Why is the economy so affected by changes in house prices? Think about what happens when construction workers lose their jobs and how this affects aggregate demand. Then consider how the macroeconomy will be affected.
  5. When demand for houses increases, why do prices increase so rapidly? Consider elasticity.

Oil affects our everyday lives. Whether it’s to heat your house, to run your car or to work out production costs, the price of oil is important. Commodity prices are determined by the interaction of demand and supply and oil prices are no different. As demand and supply for products and for oil itself change, so will the price of oil. However, any changes in the price of this valuable commodity will also have effects on macroeconomic variables, such as inflation. From a high of $147 (£90) per barrel in July 2008, it fell to $30 by the end of the year. But since then it doubled to reach $60 by May and has been around the $70 mark since.

How have these fluctuations affected the economy? Should more be invested in extraction? Extracting oil is an expensive process and requires huge investment, which is problematic given the current recession and various funding issues. The following articles consider this problem, as well as the impact it is likely to have on our economic recovery.

Questions

  1. How is the price of oil determined? Why is it so volatile? How is price elasticity of demand relevant to your answer?
  2. Over the coming ten years, which factors are likely to affect (a) demand for oil (b) supply of oil?
  3. Explain whether the price of oil is likely to rise faster or less fast than general prices.
  4. How do changes in the price of oil affect the government’s macroeconomic objectives and its policy decisions?
  5. Explain why the price of oil is such an important consideration for firms

Up until a year ago, milk and cheese prices were soaring woldwide (see Cheddar – the king of cheeses at £2000 per tonne). A surging world economy and rapidly growing demand from China and India were driving up commodity prices, including milk and milk-based producs. In the UK, average farmgate prices for milk had risen from 19 pence per litre (ppl) in 2006 to 27.4ppl by October 2008 (see here for data). Since then, however, as the global economy has plunged into recession, milk prices have fallen. By September 2009, the farmgate price had fallen by over 18 per cent to around 22.4ppl. With rising costs for fuel and cattle feed, many dairy farmers are now making a loss and are either quitting, or considering quitting, the industry.

It’s a similar story in Europe, North America and other dairy producing regions of the world. In Europe “the mood is turning sour. Last week 300 tractors dragged milk containers over fields in southern Belgium, dumping a day’s worth of production (see video). Similar protests were made in Germany, France, the Netherlands and Luxembourg. The crisis has driven many EU farmers into a ‘milk strike’, with thousands refusing to deliver to the industrial dairy conglomerates that produce everything from skimmed milk to processed cheese.”

So is this just market forces in action and will prices rise again as the world economy recovers? Or is it a reflection, in part, of the monopsony power of the supermarkets and the milk processing industry? The following articles look at the issues, both in the UK and the rest of Europe and in the USA.

Questions

  1. For what reasons are many dairy farmers now making a loss?
  2. For what reasons has the power balance in the wholesale milk market shifted towards milk purchasers (such as supermarkets) and away from farmers?
  3. How would a phased liberalisation of EU milk production help the UK’s dairy farmers?
  4. Discuss the likely effectiveness of the European Commission’ proposed measures to help dairy sector in short, medium and long term.
  5. What is likely to happen to milk prices over the next two years and what will be the likely effect on supply? Explain your answer and consider the relevance of price elasticity of supply.
  6. “Agriculture officials and farmers in Vermont, New Hampshire and Massachusetts have launched a program called Keep Local Farms. … Organizers say they hope to appeal to consumers’ growing taste for local foods” (see final linked article above). What determines the likely effectiveness of such ‘buy local’ movements? What incentives are there for people to buy local? If countries in general encourage people to buy local, is this a zero sum game? Explain.

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!
