As the news from the Gulf of Mexico goes from very bad to even worse, so BP is increasingly coming under the international spotlight for its approach to risk management and safety. Was it sufficiently cautious? Could the accident on April 20 that killed 11 men and has been gushing some 800,000 gallons per day of crude oil into the sea have been averted? When the consequences of a pipe rupture are so catastrophic, is ‘catastrophic risk’ appropriately priced? As Tony Hayward, BP’s Chief Executive, told the Financial Times (see links below): “It was ‘an entirely fair criticism’ to say the company had not been fully prepared for a deep-water oil leak.”

One insight into BP’s approach to risk has come to light with the leaking of a 2002 memo from BP on how human life ought to be valued in any cost–benefit analysis of a project. As the Chicagoist summarises the memo:

A two page document prepared by risk managers in 2002 titled “Cost benefit analysis of three little pigs” shows the type of thinking BP put into risk assessment. The memo shows, in cartoonish fashion, that blast resistant trailers for BP’s workers weren’t necessary, because the cost was too high. In 2005, a refinery caught fire, killing 15 and injuring 170 people.

So how should catastrophic risk be taken into account? What does a company do when the probability of a disaster is extremely low and yet the costs of such a disaster, were it to occur, are extremely high?

Below you will find links to the manifestos of the three main UK-wide parties for the general election on May 6. It’s not our role to suggest to those of you living in the UK with the right to vote how you should vote. The one thing we would suggest is that you consider carefully what the parties are proposing.

What is clear is that the state of the economy and the policies necessary to tackle economic problems are central to all the manifestos. As a student of economics, you should be able to assess the manifestos in terms of how the parties set out the economic problems facing the UK and what they propose doing about them.

So look through the manifestos below and then answer the questions we’ve posed about the UK economy and about the economic policies being proposed. If you are uncertain about how to answer them, then ask yourself what extra information would I need to enable me to give a good answer.

The manifestos (in alphabetical order)
The Conservative Party manifesto
The Labour Party manifesto
The Liberal Democrat Party manifesto

Other sources
We are reluctant to recommend newspaper articles, as all newspapers at election time tend to be highly partisan and are therefore likely to give you a very specific ‘spin’ on the parties’ proposals. Perhaps the two best independent sources are the BBC and the Institute for Fiscal Studies. See:
Election analysis 2010 Institute for Fiscal Studies
Election 2010 BBC News
Stephanomics Stephanie Flanders’ blog (this links to the archive).

Questions

  1. How do the analyses of the economic problems facing the UK differ between the three manifestos?
  2. Compare the policies of the three parties for cutting the public-sector deficit. Consider the following issues: the size and nature of any cuts in government expenditure; the size and nature of any tax increases; the timing of the meaures.
  3. What assumptions are being made about the determinants of aggregate demand over the coming months and the role of fiscal policy in this?
  4. Compare the policies of the three parties towards the distribution of income. To what extent have the parties taken into account possible incentive/disincentive effects of policies of redistribution?
  5. To what extent are the parties proposing using the tax system to tackle problems of externalities? Give examples and assess how effective the policies are likely to be.
  6. To what extent do each of the manifestos leave you with unanswered questions about the economy and how their proposed policies will tackle economic problems?

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.

Questions

  1. Why does the market fail to achieve the socially optimal amount and pattern of road use?
  2. What externalities are involved in road use?
  3. What are the arguments for and against increased road building as the solution to traffic congestion?
  4. Assess the arguments for and against road pricing
  5. If increasing use is to be made of road pricing, what is the best form for road pricing to take?

  7. Assuming you were in government and were acutely aware of how your policies might be perceived by the public and the press, what would you do about traffic 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.

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?
