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.

Questions

1. Use supply and demand analysis to illustrate the reasons for the shortages in diesel in Bolivia.

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.

Questions

1. Using supply and demand diagrams as appropriate, illustrate the ways in which price controls have been used to influence prices in Argentina and Russia and China.
2. Examine the reasons why the Argentinean government has chosen to implement price controls for energy.
3. Discuss the likely effectiveness of price controls in combating inflation in Russia, China and Argentina.

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.

You do perhaps need to check the date for this story, but once you have established that it wasn’t written on April 1st, you can start to take it a little more seriously. An alliance of an American oil company and food producer is to turn pig fat into diesel fuel. The fuel will apparently have the same chemical properties as diesel but a lower carbon dioxide content and zero sulphur, so should be beneficial for the environment the companies argue.

Pig fat to be turned into diesel BBC News Online (19/4/07)

Questions

1. Using diagrams as appropriate, compare and contrast the environmental impact of conventional diesel and the new pig fat bio-diesel.
2. Discuss the extent to which the new pig fat diesel will be better for the environment than conventional diesel.
3. Evaluate two policies that the government could implement to encourage the use of alternative fuels like the new pig fat bio-diesel.

Changes in house prices could be considered a national obsession in the UK and recent speculation about a property crash or a crash in the buy-to-let sector of the market has been no exception. Many commentators differ about the possible direction of house prices with average annual increases of around 10% continuing. So will the sector crash? Or won’t it? The articles below consider some of the issues on the supply side and the demand side of the market.
