One of the key Budget measures was a change in the car tax regime. The Chancellor, Alistair Darling, introduced a new banded system annual vehicle excise duty (VED) based on the level of emissions of the vehicle. The cars with the lowest levels of emissions will be exempt from VED, but at the other end of the spectrum, the highest polluting vehicles will face an annual VED of around £440. However, this will be substantially higher in the year of purchase of the vehicle and this so-called ‘showroom tax’ will raise the tax level to £950 in the first year of purchase.

Questions

1. Explain how the highest polluting vehicles affect the socially optimal equilibrium in the market for car travel.
2. Using supply and demand diagrams as appropriate, illustrate the likely impact of the new car tax regime in 2009-10 on the equilibrium in the market for car travel. What is the significance of the concepts of price elasticity of demand and consumer surplus in your analysis?
3. Discuss the likely effectiveness of the new banded car tax regime at reducing the average level of emissions from cars. Would raising the tax on petrol and diesel be a more efficient method of achieving the same goal?

The Civil Aviation Authority (CAA) – the regulatory body for Britain’s airports – has allowed the main airport operator BAA to increase substantially the landing charges it levies on airlines. The airlines have reacted angrily and argued that the higher charges will simply be passed on to passengers in the form of higher fares.

BAA to raise landing fees BBC News Online

Questions

1. Explain the regulatory system in operation for the control of landing fees at UK airports .
2. Explain why the CAA has increased the landing fees that BAA can charge for planes landing at UK airports.
3. Is raising landing fees an efficient method of internalising the externalities associated with air travel?
4. Evaluate the extent to which the higher landing fees will be passed on to airline passengers. Use diagrams as appropriate. You may also like to consider the relevance of the price elasticity of demand for air travel in determining the extent to which the higher landing fees can be passed on by the airlines.

2008 may yet come to be seen as the year that marks the death of the single-use plastic bag. Many countries around the world, including China, have banned their use and February 2008 has seen Marks and Spencer announcing a 5p charge per plastic bag in an attempt to reduce their usage. Even government departments have faced criticism over their use as promotional tools. For more details on plastic bag bans and policies relating to limiting their usage, see our 2007/8 podcast on The economics of plastic bags elsewhere on the site.

Questions

1. What are the social costs and benefits resulting from the use of single-use plastic
bags?
2. Using diagrams as appropriate, show how the equilibrium price and quantity of plastic bags differs from the social optimum.
3. Evaluate two possible policies that the government could use to reduce the use of plastic bags.

In the article below, Ashley Seager from the Guardian argues that the government is doing little to encourage the take-up and adoption of alternative forms of energy generation for households. Indeed he argues hat the situation has got worse and not better in recent months with changes in the system. Only 270 houses were helped with the fitting of photovoltaic systems last year. In Germany the equivalent figure was 130,000.

Questions

1. Assess the external costs and external benefits resulting from installing a photovoltaic electricity generation system on a house.
2. Using diagrams as appropriate, show how the installation of photovoltaic cells on houses will alter the socially optimal market equilibrium.
3. Evaluate two policies that the government could use to encourage the more widespread adoption of alternative methods of generating power.

Rapidly rising food prices have led to instability in many countries and have fuelled inflation in less developed economies where food spending is a greater proportion of overall consumer spending. A number of factors have contributed to this rapid rise in prices, but one important contributory factor is the move towards growing crops that can be used as bio-fuels in the developing world and this shift in production is having a knock-on effect in world food markets.
