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.

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’?
Oil prices have been rising in recent weeks. At the beginning of October 2010, the spot price of Brent Crude was $80 per barrel. By December it has passed $90 per barrel. There is some way to go before it gets to the levels of mid-2008, when it peaked at over $140 per barrel (only then to fall rapidly as the world slid into recession, bottoming out at around $34 per barrel at the end of 2008).
Higher oil prices are a worry for governments around the world as they threaten higher inflation and put recovery from recession in jeopardy. You will probably have noticed the higher petrol prices at the pumps. If you spend more on petrol, you will have less to spend on other things.
So why have oil prices risen and are they likely to continue rising? The following articles examine the causes of the recent surge and look ahead to the likely response from OPEC and the path of oil prices next year.

Questions
- Explain why oil prices have been rising. Use a diagram to illustrate your answer.
- How can the concepts of price elasticity of demand, income elasticity of demand and price elasticity of supply help to explain the magnitude of oil price movements?
- Examine what is likely to happen to oil prices over the coming months. What are likely to be the most important factors in determining the direction and size of the price movements? Distinguish between demand-side and supply-side effects in your answer.
- What are ‘crude futures’? Explain how actions in the futures market are likely affect spot prices.
- To what extent can OPEC control oil prices?
- If crude oil prices go up by x%, would you expect petrol station prices to go up by approximately x%, or by more than or less than x%? Explain.
- Why have central heating oil prices risen by around 70% of over the past three months? What are the implications of your answer for the type of market structure in which central heating oil companies are operating?
Multinational companies bring many advantages to host nations. Whether it is creating jobs, income, investment or sharing technology, governments across the world try to encourage firms to set up in their country. However, once a multinational has been set up, it’s natural for the owners and managers to favour their own countries when decisions have to be made. If there is some new investment planned, where to put it will be a key decision and not just for the firm. New investment may mean new jobs and better working environments. If job cuts are necessary, the decision-maker’s country of origin may determine where they occur.
This so-called ‘Headquarters effect’ is apparent in the case of Siemens, which has guaranteed the safety of all German jobs, both now and in the future. Those employees in the UK are understandably concerned. If job cuts are needed and German workers will not be affected, it takes little intelligence to realise that their jobs may be at risk. The following discussion by Robert Peston considers this issue.

Questions
- What is the ‘Headquarters effect’?
- The article states: “The HQ effect implies that when a British plant is owned by an overseas company, it may be more vulnerable to being closed down if the going gets tough”. Why is this the case?
- What are the advantages and disadvantages of multinational investment to (a) the multinational company and (b) the host country?
- How is multinational investment affected by the business cycle?
- It Trent UK were to shut down or if a particular office was closed in one part of the country, what type of unemployment would be created?
Russia is now ranked alongside Zimbabwe on the worldwide corruption index, despite the fact that the Russian authorities have been doing their best to tackle it. The Russian bribery ‘industry’ is worth some $300 billion per year and those who can be bought include several government officials.
The Russian economy is in much need of foreign investment, but the growing world of bribery is deterring international businesses from investing in Russia. Not only will they face the costs of building and running the business, but they are also likely to face substantial costs in trying to get the paperwork through, as IKEA found. Having said that they would never resort to bribery, IKEA had to pay $4 million for investment in local infrastructure and donate a further $1 million for local government projects just to get the 300+ permits they needed to begin construction. This then led to further bribes and a number of lawsuits. For some companies, the delays caused by not paying a bribe may actually cost more than the bribe itself.
The following webcast and articles look at the case of IKEA and the push by foreign businesses to avoid the clutches of Russian bribery.

Questions
- Why is Russia in need of significant foreign investment? How would it help the economy?
- Can we classify IKEA (or any other company that uses bribery) as a risk-lover? Explain your answer.
- If a foreign firm wants to invest in Russia, which type of expansion do you think would be the easiest and the least open to bribery?
- IKEA began building without the necessary permits, but then ‘the bureaucrats took advantage of the situation’. Was IKEA operating under conditions of risk or uncertainty?
- In the article ‘IKEA masters rules of business’, Lennart Dahlgren said: “If we had waited to receive them all, we would have lost years”. What economic concept is being referred to?
- To what extent is government intervention and international co-operation needed to tackle corruption in Russia?
