Oil prices have seen a relentless rise in recent weeks with much speculation that they will go over $100 a barrel in the near future. The high oil price has seen the average price of petrol go over £1 per litre in the UK, shortages and rationing in Tehran and violence in Yemen. So what is causing oil prices to rise and what impact is this likely to have on the global economy?

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.

Bolivia may have the second largest gas reserves in Latin America but it also has an acute shortage of diesel. People have blamed a variety of causes: smugglers, the government and nationalisation. In truth, the cause may be a combination of all these factors, but whatever the cause, the diesel shortage is acting as a significant constraint on further economic development and is an ongoing headache for the President Evo Morales.

Price controls – limiting the price of goods through government intervention in a market – have fallen out of fashion to a great extent as an economic policy tool in the past couple of decades, but they may be making a comeback in Argentina, Russia and China according to the article below from Slate magazine.

Independent school fees have generally risen faster than inflation and a relatively inelastic value of the price elasticity of demand seems to have led to their revenues increasing. Demand has stayed high despite the above-inflation fee increases. However, a recent report suggests that fees have risen relative to average earnings and that independent schools have become less affordable. This may, the report argues, make some schools relatively more vulnerable to a fall in the number of places demanded.

Public school fees ‘risk pricing parents out’ Guardian (18/9/2007)

Questions

1. Identify the main factors affecting the value of the price elasticity of demand for places at independent schools.
2. Discuss the extent to which the value of the price elasticity of demand for places at independent schools is likely to change as fees increase relative to average earnings.
3. Assess the extent to which competition in the market for independent schools affects the level of fees (the market price) and the value of the price elasticity of demand for places.
