Tag: cross-price elasticity of demand

Are we heading for ‘perfect storm’ in commodity production and prices? Certainly the prices of many commodities have soared in recent months. These include the prices of foodstuffs such as dairy products, cooking oils and cereals, crude oil, cotton, metals and many other raw materials. The overall world commodity price index has risen by 28% in the past 12 months. The following are some examples of specific commodities:

Price rises in the 12 months to February 2011

• Wheat 62%
• Maize 59%
• Coffee 70%
• Beef 39%
• Sugar 46%
• Palm kernal oil 142%
• Soybean oil 50%
• All food price index 32%
• Crude oil 20%
• Cotton 132%
• Fine wool 55%
• Softwood timber 25%
• Iron ore 78%
• Copper 29%
• Tin 55%
• All metals index 58%
• Rubber 79%.

The problems are both short term and long term, and on both the demand and supply sides; and the effects will be at micro, macro and global levels. Some hard choices lie ahead.

The following webcast, articles and reports explore both the current position and look into the future to ask whether rising commodity prices are likely to continue or even accelerate.

The first link is to a BBC World Debate which considers the following issues: “Is scarcity of natural resources a serious challenge for developing and advanced economies? How great is the risk that scarcity might lead to conflict, both within and between nations? Might a scramble for resources lead to a retreat from globalisation and to greater protectionism?”

Questions

  1. Identify the various factors that are causing rises in commodity prices. In each case state whether they are supply-side or demand-side factors.
  2. How can the price elasticity of demand and supply, the income elasticity of demand and the cross-price elasticity of demand be used to analyse the magnitude of the price rises?
  3. To what extent are rising food prices the result of (a) short-term (i.e. reversible) factors; (b) long-term trends?
  4. Why are food prices in the shops rising faster in the UK than in many other countries?
  5. To what extent is the future of food security and prices and moral issues?
  6. Why may current oil price rises become an opportunity for the future?
  7. What might be the respective roles be of government, business and consumers in responding to natural resource constraints?

The annual Agricultural Outlook for the next ten years has just been published jointly by the OECD and the UN Food and Agriculture Organization (FAO). Click here and here for audio presentations of the report by the FAO’s Jacques Diouf and the OECD’s Angel Gurría.

The report argues that world recovery will raise agricultural prices. This will be partly the direct result of higher demand and partly the result of higher prices of agricultural inputs, such as fertilisers and fuel. But prices will not rise back to the peak levels of 2007/8. These higher prices, however, would have a positive effect on world food output, especially in the BRICs (Brazil, Russia, India and China). This, in turn, would limit the price rises.

So is this good news for food producers and consumers? The following articles look at the issues

Questions

  1. Explain what is likely to happen to food prices. What are the explanations given in the report?
  2. Represent the analysis on a supply and demand diagram (or diagrams).
  3. What is the relevance of (a) income elasticity of demand, (b) price elasticity of demand, (c) cross-price elasticity of demand, (d) price elasticity of supply, in explaining the likely future movements of food prices and why some food prices are likely to rise faster than others?
  4. What factors are likely to impact on the production of food in developing countries?

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?

With recession biting, many people are cutting back on spending. This has not been even across products, however. People have tended to shift from more luxurious products, such as foreign holidays and branded products, to holidays at home and supermarkets’ own-brand products (see Shoppers opt for supermarket brands Financial Times (4/8/09)). There has also been a decline in spending on consumer durables, such as cars, furniture and kitchen appliances.

One sector that has fared better than most, however, is the teenage market. “So far it seems teenagers have not cut back on their shopping. Teen-targeted retailers such as Primark, New Look, H&M, Asos and Hot Topic are all weathering the recession better than rivals aimed at an older demographic.” This is a quote from the first of the two linked articles below, which look at this market and its future prospects.

Questions

  1. How is spending on particular products during a recession related to their income elasticity of demand? How does the income elasticity of demand depend on the length of the time period under consideration?
  2. Why has the teenage market been less susceptible to the recession than many other markets?
  3. To what extent will being ‘bargain savvy’ be enough for teenagers to survive the recession without having to make substantial changes in spending patterns? Consider the concept of price elasticity of demand in your answer.

22nd November marks the day when Americans celebrate Thanksgiving Day. However, the cost of this celebration has increased by 11% in the last year according to figures from the American Farm Bureau Federation. One of the main causes of this is the rise in turkey prices but other factors were important as well.

Questions

1. Using supply and demand analysis, illustrate the price changes for turkeys identified in the article.
2. Consider possible factors that may have led to the price changes for turkeys identified in the article.
3. Discuss the likely change in the quantity of turkeys demanded as a result of the price rise.
4. What is the likely approximate value of the cross elasticity of demand for cranberry sauce with respect to the price of turkeys?
