Billions of plastic bags are used and discarded each year around the world and these cause considerable environmental damage – a form of market failure. In this podcast we consider the extent of the problem and policies that countries around the world are adopting to try to minimise this market failure. Many countries, including China, have banned single-use plastic bags completely, while others, such as Ireland, have chosen to tax them to try to limit their use.

Britain’s recycling strategy is under risk following a collapse in waste paper prices. Three quarters of UK waste paper is exported to Far Eastern buyers, but demand from this region has collapsed in recent months. The price collapse has led to a surplus of recyclable paper and some local authorities have proposed using Ministry of Defence (MoD) sites to store the waste while there is no market or use for it.

Questions
- Define the terms (i) private cost and (ii) external cost.
- What are the external costs resulting from disposing of waste paper and other recyclable products in landfill sites?
- Using diagrams as appropriate, illustrate the changes that have taken place in the market for waste paper.
- Evaluate two strategies that the government could adopt to increase the price of waste paper.
- Discuss the likely success of a policy of storing waste on MoD sites to await an upturn in the recycling market..
“The economic crisis is petty by comparison to the nature crunch. But they have the same cause.” This is how George Monbiot starts his article below. The comparison between the financial crisis may seem an unlikely one, but global warming and the resultant economic costs could also have a significant effect on the world economy.

Questions
| 1. | Define the terms (i) external cost (ii) private cost (iii) social costs. |
| 2. | Using diagrams as appropriate show the reasons why the market economy may fail to allocate scarce resources appropriately. |
| 3. | “If the global economy keeps growing at 3% a year (or 1700% a century) it too will hit the wall.”. Discuss possible policies that may help prevent this situation arising. |
A significant illegal trade in ‘e-waste’ has developed with thousands of discarded computers arriving every day in the ports of West Africa. Once there, children are often used to dismantle them and extract metals . However, this has resulted in huge toxic dumps and serious health problems for resident in the surrounding area.

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? |
