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?

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!

  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?

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.
