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
- Identify the various factors that are causing rises in commodity prices. In each case state whether they are supply-side or demand-side factors.

- To what extent are rising food prices the result of (a) short-term (i.e. reversible) factors; (b) long-term trends?
- Why are food prices in the shops rising faster in the UK than in many other countries?
- To what extent is the future of food security and prices and moral issues?
- Why may current oil price rises become an opportunity for the future?
- What might be the respective roles be of government, business and consumers in responding to natural resource constraints?
Periodically, the BBC hosts debates on major global topics. The following links are to the January 2011 debate on the state of the world economy and on what policies governments and central banks should pursue.
Should governments be boosting aggregate demand by raising government expenditure and cutting taxes in order to stimulate growth and plan to bring down deficits over the long term once growth is established? Or should they embark on tough fiscal consolidation now by cutting government expenditure and/or raising taxes in order to stimulate confidence by international financiers, thereby keeping long-term interest rates down and creating the foundations for sustainable economic growth? The debate considers these two very different policy approaches.
The participants in the debate are Joseph Stiglitz (Professor of Economics, Columbia University), Christina Romer (Professor of Economics, University of California, Berkeley and Adviser to Barack Obama (2009–10)), George Papaconstantinou (Finance Minister of Greece), Dominique Strauss-Khan (Managing Director, IMF) and Zhou Xiaochuan (Governor, Chinese Central Bank). The debate is in five separate webcasts.

Questions
- What are the arguments for maintaining economic stimulus, at least for the time being? What are the relative merits of fiscal and monetary stimulus? Explain whether such policies are consistent with Keynesian polcies.
- What are the arguments for tough fiscal consolidation? Explain whether such policies are consistent with new classical policies.
- How successful have US policies been in stimulating the US economy?
- What role can China play in the recovery and long-term growth of the global economy and are there any imbalances that need correcting?
- Why might countries’ domestic policies result in currency wars? Is currency realignment necessary for sustained global growth?
- How important are consumer and business confidence to short-term recovery and long-term growth and to what extent do government policies respond to swings in confidence?
The world’s population is set to go on rising – at least to 2050. And as population rises, so will the demand for food. But here we come up against a potentially catastrophic illustration of the law of diminishing returns. Population is set to grow, but the world supply of land is pretty well fixed. And with global warming, some land may become unusable.
According to Sir John Beddington, an expert in population biology and lead author of a government-commissioned report, The Future of Food and Farming, there could be serious consequences of this population rise, including rapid rises in the demand for food, rising food prices, rising land prices, the degradation of land, growing food poverty in many developing countries, growing political unrest and serious environmental damage. As the report’s Executive Summary states:
The global food system will experience an unprecedented confluence of pressures over the next 40 years. On the demand side, global population size will increase from nearly seven billion today to eight billion by 2030, and probably to over nine billion by 2050; many people are likely to be wealthier, creating demand for a more varied, high-quality diet requiring additional resources to produce. On the production side, competition for land, water and energy will intensify, while the effects of climate change will become increasingly apparent. The need to reduce greenhouse gas emissions and adapt to a changing climate will become imperative. Over this period globalisation will continue, exposing the food system to novel economic and political pressures.
Any one of these pressures (‘drivers of change’) would present substantial challenges to food security; together they constitute a major threat that requires a strategic reappraisal of how the world is fed.
The report specifically looks at five key challenges for the future:
A. Balancing future demand and supply sustainably – to ensure that food supplies are affordable.
B. Ensuring that there is adequate stability in food prices – and protecting the most vulnerable from the volatility that does occur.
C. Achieving global access to food and ending hunger – this recognises that producing enough food in the world so that everyone can potentially be fed is not the same thing as ensuring food security for all.
D. Managing the contribution of the food system to the mitigation of climate change.
E. Maintaining biodiversity and ecosystem services while feeding the world.
So what can be done and how realistic are the policy solutions? The following broadcasts and articles examine the arguments

BP has just published its latest projection of energy trends – its Energy Outlook 2030. According to the press release:
World energy growth over the next twenty years is expected to be dominated by emerging economies such as China, India, Russia and Brazil while improvements in energy efficiency measures are set to accelerate.
The following podcast from the Financial Times features a discussion of the report and the factors affecting oil prices and their relationship to economic growth

Questions
- What are the most powerful driving forces behind the demand for energy?
- Why does the report forecast virtually no increase in energy demand in developed countries? What assumptions are made about growth rates in OECD and non-OECD countries?
- What factors would lead to a substitution of sustainable energy sources for fossil fuels? What would detrmine the size of such substitution?
- What is the role of the price elasticity of demand for and supply of oil and the income elasticity of demand for oil in determining oil consumption in different parts of the world?
- Why may high energy prices not necessarily mean ‘doom’?
Bank rate in the UK has been at the historically low level of 0.5% since March 2009 and the MPC decision on 13 January was to leave the rate unchanged (see also). But inflation has been well above the Bank of England’s target of 2% since December 2009 and it could well rise further as international commodity prices are soaring. Some economists are thus arguing that Bank rate should rise. This is crucial, they say, to dampen inflationary expectations.
Other economists, however, argue that aggregate demand is likely to remain depressed and that the economy is operating with a large negative output gap. What is more, house prices are falling, as are real wages (see Bosses gain – workers’ pain)
In the following extract from BBC Radio 4’s Today Programme, two economists, Charles Goodhart and Willem Buiter, both former members of the MPC, debate the issue.
