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.

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.

The combination of high global demand for milk and variable weather has led to a rapid rise in the price of milk. Cheese is made from milk (sorry to state the obvious!) and so cheese prices have risen to a new high in excess of £2000 per tonne and further price hikes are expected. One conclusion that could be drawn from this is that it is better to have a takeaway pizza now rather that in a month’s time, but what other effects is this price increase for milk likely to have?

Questions

1. Identify the key determinants of demand for cheese.
2. Using diagrams as appropriate, illustrate and explain the changes that have taken place in the market for cheese.
3. Assess the extent to which the price increase for milk can be passed on to consumers of associated products like yoghurt and cheese.

January 2007 saw unseasonably cold weather in California and the big freeze that occurred may have destroyed up to 70% of the Californian orange crop. Prices as a result of oranges are likely to treble in US shops. The impact on prices elsewhere in the world may be less, but is still likely to be significant as California is an important area in global terms. Oddly the price of orange juice is unlikely to be affected as very few of the Californian oranges go for turning into juice. The majority of oranges for juice are grown in Florida.

Questions

1. Using supply and demand diagrams as appropriate, explain the impact of the freezing weather in California on the world price of oranges.
2. Using supply and demand diagrams as appropriate, compare and contrast (a) the change in the price of oranges and orange juice and (b) the change in the price of oranges in the USA and the rest of the world..
3. Examine the likely impact of the cold weather in California on prices of other foods.
