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.

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.

In 2010/11, government funding for UK universities will be 7 per cent less (£518m) than in 2009/10. This has led to calls for substantial increases in student fees in order to stave off a serious funding crisis for many universities. One such call has come from David Blanchflower. As the first article below states:

“A leading economist has called for students from well-off families to be charged the ‘market rate’ of up to £30,000 a year to go to university. David ‘Danny’ Blanchflower, a former member of the Bank of England’s monetary policy committee, said the “poor have been subsidising the rich” for too many years.”

But just what are the arguments for and against a substantial rise in fees and who should pay any rise in fees? Should it be only students of very well-off parents or should it include middle-income parents too? Or if student loans are available to cover higher fees, why should not the same fees apply to all students? Then there is the question of who benefits from a university education? How much should external benefits be taken into account?

Questions

  1. Why is the government planning to make substantial cuts to university funding?
  2. What are the arguments for and against the university sector bearing a larger percentage cut than most other areas of government expenditure?
  3. Should any rise in fees be born by parents or by students from future income?
  4. Identify the external benefits from higher education? How does the existence of such externalities affect the arguments about the appropriate charges for higher education?
  5. What are the economic arguments for and against moving towards more two-year degrees.
  6. Discuss the case for and against increasing the participation rate in higher education to 50 per cent of young people.
  7. Is higher education a ‘merit good’ and, if so, what are the implications for charging for higher education?

At the end of two weeks of often acrimonious wrangling between representatives from 193 countries, an agreement – of sorts – was reached at the climate change summit in Copenhagen. What was this agreement? It was an ‘accord’ brokered by the USA, China, India, Brazil and South Africa.

This Copenhagen Accord contains three elements. The first is a recognition of the need to prevent global temperatures rising by more than 2 degrees Celsius above pre-industrial levels. The second is a commitment by developed countries to give $30bn of aid between 2010 and 2012 to developing countries for investment in green technology and to mitigate the effects of climate change. In addition, a goal was set of providing $100bn a year by 2020. The third is for rich countries to give pledges on emissions reductions and for developing countries to give pledges on reducing emissions increases. Developed countries’ pledges will be scrutinised by the UN Framework Convention on Climate Change, while developing countries will merely be required to submit reports on their progress in meeting their pledges.

But this is only an accord. It has no legal status and was merely ‘recognised’ by the countries at the conference. What is more, the target of limiting temperature rises to 2C does not contain a date by which temperature rises should peak. Also, as countries are not required to submit targets for emissions until February 2010, it is not clear how these targets will be kept low enough to meet the temperature target and there is no identification of penalites that would apply to countries not meeting their pledges.

Not surprisingly, reactions around the world have been mixed. The following podcasts and articles look at these reactions and at the economic mechanisms that will be required to meet the 2C limit

Questions

  1. What incentives exist for countries to agree to tough pledges to reduce emissions?
  2. Was the very limited nature of the Copenhagen Accord a Nash equilibrium? Explain.
  3. Is the carbon price a good indicator of the effectiveness of measures to curb emissions?
  4. Must any agreement have verifiable targets for each country of the world if it is to be successful in curbing carbon emissions?
  5. Is a cap-and-trade system the best means of achieving emissions reductions? Explain.

The New Economic Foundation (NEF) is “an independent think-and-do tank that inspires and demonstrates real economic well-being.” It aims “to improve quality of life by promoting innovative solutions that challenge mainstream thinking on economic, environmental and social issues. We work in partnership and put people and the planet first.” It has just published a study into pay, A Bit Rich: Calculating the real value to society of different professions (see link below). This argues that narrow notions of productivity, whilst having some relation to pay, are a poor way of judging the worth of particular jobs to society.

“In this report NEF … takes a new approach to looking at the value of work. We go beyond how much different professions are paid to look at what they contribute to society. We use some of the principles and valuation techniques of Social Return on Investment analysis to quantify the social, environmental and economic value that these roles produce – or in some cases undermine.

Our report tells the story of six different jobs. We have chosen jobs from across the private and public sectors and deliberately chosen ones that illustrate the problem. Three are low paid – a hospital cleaner, a recycling plant worker and a childcare worker. The others are highly paid – a City banker, an advertising executive and a tax accountant. We recognise that our incentives are created by the institutions and systems around us. It is not our intention therefore, to target the individuals that do these jobs but rather to examine the professions themselves.”

So, to what extent do rates of pay reflect the ‘true value’ of what is being created? How could we establish this ‘true value’? Does pay even reflect marginal productivity in the narrow private sense? The report and the articles look at these issues.

Questions

  1. What is meant by the marginal productivity theory of wage determination? Does the NEF study undermine this theory? Explain.
  2. Why are elite bankers, tax accountants and advertising executives paid so much more than hospital cleaners, waste recycling workers and childcare workers?
  3. “Until the prices of goods and services reflect the true costs of their production, incentives will be misaligned. This means damaging activities will be relatively cheap and profitable, while positive activities will be discouraged.” Explain this statement and whether you agree with it.
  4. To what extent can the misalignment of pay and social worth be explained by externalities?
  5. What is the basis for arguing that tax accountants and City bankers have negative social worth? Do you agree? Explain.
  6. What would happen if hospital cleaners were give a pay rise and bankers given a pay cut so that cleaners ended up with a higher pay than bankers?
  7. In the light of the NEF study, what policies should the government adopt toward pay inequality?
