Traffic congestion is both frustrating and costly. As The Economist article below states:
Congestion does more than irritate drivers. It makes employees and deliveries late, it snarls up modern “just-in-time” supply chains and it clogs up labour markets by making commuting difficult. The cost of all this is almost impossible to measure. But a big review of transport carried out by Rod Eddington, a one-time boss of British Airways, put the cost between £7 billion and £8 billion ($10.6-$12.2 billion) a year.
So what can be done about it? The report, published by the Confederation of British Industry (CBI), looks at various solutions. These range from staggering work times, car sharing and working from home, to improving roads and road pricing.
As economists we should look at the relative costs and benefits of alternative solutions in coming to sensible policy solutions. The problem is that people are often very emotional about traffic schemes. They may complain about sitting in traffic jams, but don’t want to pay to tackle the problem. There is thus a political element in any debate about solutions. Not surprisingly, the government has shied away from introducing road pricing
So what are the best solutions to traffic congestion and how do we overcome the political obstacles? The following articles look at these questions.

Transport issues in the UK are always newsworthy topics, whether it is train delays, cancelled flights, the quality and frequency of service or damage to the environment. Here’s another one that’s been around for some time – high-speed rail-links. Countries such as France and Germany have had high-speed rail links for years, but the UK has lagged behind. Could this be about to change?
The proposal is for a £30bn 250mph high-speed rail link between London and Birmingham, with the possibility of a future extension to Northern England and Scotland. This idea has been on the cards for some years and there remains political disagreement about the routes, the funding and the environmental impact. Undoubtedly, such a rail-link would provide significant benefits: opening up job opportunities to more people; reducing the time taken to commute and hence reducing the opportunity cost of living further away from work. It could also affect house prices. Despite the economic advantages of such a development, there are also countless problems, not least to those who would be forced to leave their homes.
People in the surrounding areas would suffer from noise pollution and their views of the countryside would be changed to a view of a train line, with trains appearing several times an hour at peak times and travelling at about 250mph. Furthermore, those who will be the most adversely affected are unlikely to reap the benefits. Perhaps the residents of the Chilterns would be appeased if they were to benefit from a quicker journey to work, but the rail-link will not stop in their village. In fact, it’s unlikely that they would ever need to use it. There are significant external costs to both the residents in the affected areas and to the environment and these must be considered alongside the potential benefits to individuals, firms and the economy. Given the much needed cuts in public spending and the cost of such an investment, it will be interesting to see how this story develops over the next 10 years.

Questions
- Make a list of the private costs and benefits of a high-speed rail link.
- Now, think about the external costs and benefits. Try using this to conduct a Cost-Benefit Analysis. Think about the likelihood of each cost/benefit arising and when it will arise. What discount factor will you use?
- There are likely to be various external costs to the residents of the Chilterns. Illustrate this concept on a diagram. Why does this represent a market failure?
- How would you propose compensating the residents of the Chilterns? Are there any problems with your proposal?
- Will such a rail link benefit everyone? How are the concepts of Pareto efficiency and opportunity cost relevant here?
- To what extent would this rail link solve the transport problems we face in the UK. Think about the impact on congestion.
There has been much criticism of the European Emissions Trading Scheme, the world’s most significant cap-and-trade (tradable permits) scheme for curbing greenhouse gas emissions. The main criticism is that the scheme has failed to make significant cuts in pollution. The cap was so loose in the first phase (2005–07) that by the end of this period, carbon was trading for as little as €0.02 per tonne. Although the cap on emissions was tightened by 7 per cent for phase 2 (2008–12) (see Economics, 7th ed, Box 12.5), causing the carbon price to rise to about €30.00 per tonne by mid 2009, since then the price has fallen as industry has cut output in response to the recession. By February 2010, the carbon price was around €12.50 per tonne (see the Guardian article Carbon price falls to new low). For carbon price data see the European Climate Change site.
The experience of the ETS has resulted in many people in the USA and elsewhere calling for the use of carbon taxes rather than cap and trade as the best means for reducing greenhouse gas emissions. Others have called for a mix of measures. In the US Senate, three senators are seeking to overturn cap-and-trade proposals and take a sector-by-sector approach to cutting emissions.
But increasingly the evidence, supported by economic argument, is that cap and trade does work – or can be made to work – and that it is a better policy tool than carbon taxes. The following articles look at cap and trade and assess whether it really is the best alternative.

UK Parliament’s Environmental Audit Committee has concluded that the European Emissions Trading Scheme (ETS) is not working as it should. Thanks to a total emissions cap that is too low in a time of recession, the carbon price has fallen. The result is that there is no longer sufficient of an incentive for firms to invest in green technology. As the Financial Times article (below) reports:
The committee has urged the government to consider other measures, such as a floor price for carbon dioxide emissions, which would provide industries with greater certainty over the price of carbon and help to ensure the system of pricing was effective.
The MPs said a price of €100 per tonne of CO2 could be necessary to encourage investment, compared with current prices of about €13.
So is the committee correct? Or is a low price of carbon merely temporary, with firms realising that the price will rise as the European economy recovers? The following articles examine the issues.

- Compare the relative merits of a cap-and-trade system with green taxes.
The UK section of the North Sea used to be sufficient to supply all of the country’s gas requirements, but now some has to be imported from countries such as Norway. With the cold weather, the usage of gas has increased to record levels and there are now concerns for future supplies, especially if the cold weather returns.
However, the National Grid has said that there isn’t a problem, despite a glitch with a Norwegian gas supply. Gas supplies from various sources have been increased to deal with this record demand. There have been calls for Britain to build more gas storage facilities and the National Grid did issue ‘gas balancing alerts’, asking power firms and other large industries to cut back on their gas consumption. There are suggestions that even if supplies of gas aren’t a problem at the moment, we could see serious shortages in a few years.
Following growing demand for gas supplies, wholesale prices rose, but they did fall again when supplies were increased. Prices of household bills could be affected in the future, but for now, it’s too soon to tell. However, rising prices could spell further trouble for ours and other economies suffering from extreme weather on top of a financial crisis. Economic recovery could be put in jeopardy.
This fear of gas shortages and security of supply has led environmental and business groups to argue that Britain needs to diversify its energy supplies and become less dependent on foreign exports. This issue fits in with the latest developments in new investment in wind turbines.
Who knew that something as beautiful as snow could cause so much trouble and provide so much economic analysis!

- To what extent should the government have been able to forecast this higher demand? Should better contingency plans have been in place?
- The article from CNN Money looks at the effect of rising prices of oil and energy and how this is likely to affect consumer spending. Why could rising prices of these commodities adversely affect economic recovery?
- What is an ‘interruptible contract’ and how useful have they been in dealing with these gas shortages?
