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

  1. Make a list of the private costs and benefits of a high-speed rail link.
  2. 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?
  3. 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?
  4. How would you propose compensating the residents of the Chilterns? Are there any problems with your proposal?
  5. Will such a rail link benefit everyone? How are the concepts of Pareto efficiency and opportunity cost relevant here?
  6. To what extent would this rail link solve the transport problems we face in the UK. Think about the impact on congestion.

From the end of January to the beginning of March, the sterling exchange rate index fell by over 6% – from 81.7 to 76.5. Against the dollar, the fall has been even more dramatic, falling from $1.62 to $1.49 (a fall of 8%). What are the reason for this? And is the depreciation likely to continue? The following clip looks at what has been going on and whether the reasons are political, or whether there are other economic fundamentals that have contributed to sterling’s fall.

As the news item, A Greek tragedy reported, the level of debt in Greece and also in Portugal, Spain, Ireland and Italy, has caused worries, not just for their creditors, but also for the whole eurozone. Here we give you the opportunity to listen to a podcast from the Guardian in which some of the paper’s main economic columnists, along with Observer commentator, William Keegan, discuss the effects of this debt on the euro. To quote the introduction to the podcast:

“In Brussels, European leaders have pledged ‘determined and co-ordinated’ action to help Greece – they won’t let it fail. Our Europe editor Ian Traynor says the announcement of a deal was designed to keep the markets happy.

But leaders of wealthier euro nations like Germany are hoping they won’t have to ask their voters to bail Greece out. Kate Connolly, our Berlin correspondent, explains why Germans are so reluctant to provide financial assistance.

It’s being seen as a defining moment for the euro. Economics editor Larry Elliott says not signing Britain up to the single currency was the best decision Gordon Brown ever made.”

Questions

  1. To what extent is Greece’s debt a problem for the whole eurozone?
  2. Consider the arguments for and against bailing Greece out (a) by stronger eurozone countries, such as Germany and France; (b) by the IMF.
  3. What support for Greece would minimise the problem of moral hazard?
  4. How would you set about establishing whether the current eurozone is an optimal currency area?
  5. How do the current problems of debt affect the arguments about whether Britain should adopt the euro?

In several of the posts in recent months we’ve considered the possible use of a Tobin tax as a means of reducing speculation in financial markets and possibly raising substantial amounts in tax revenue. See, for example: Tobin or not Tobin: the tax proposal that keeps reappearing and A Tobin tax – to be or not to be?. Although James Tobin’s original proposals referred to a tax on foreign exchange transactions, recent proposals have been to impose such a tax on a whole range of financial transactions.

Added impetus has been given to the move to adopt Tobin taxes by the publication of a video from an organisation known as the Robin Hood Tax Campaign. To quote the site “The Robin Hood Tax is a tiny tax on bankers that would raise billions to tackle poverty and climate change, at home and abroad. By taking an average of 0.05% from speculative banking transactions, hundreds of billions of pounds would be raised every year. That’s easily enough to stop cuts in crucial public services in the UK, and to help fight global poverty and climate change.”

So would this version of a Tobin tax work? The following videos and articles examine the proposal.

The health of an economy is generally measured in terms of the growth rate in GDP. A healthy economy is portrayed as one that is growing. Declining GDP, by contrast, is seen as a sign of economic malaise; not surprisingly, people don’t want rising unemployment and falling consumption. The recession of 2008/9 has generally been seen as bad news.

But is GDP a good indicator of human well-being? The problem is that GDP measures the production of goods and services for exchange. True, such goods and services are a vital ingredient in determining human well-being. But they are not the only one. Our lives are not just about consumption. What is more, many of our objectives may go beyond human well-being. For example, the state of the environment – the flora and fauna and the planet itself.

Then there is the question of the capital required to produce goods and maintain a healthy and sustainable environment. Capital production is included in GDP and the depreciation of capital is deducted from GDP to arrive at a net measure. But again, things are left out of these calculations. We include manufactured capital, such as factories and machinery, but ignore natural capital, such as rain forests, coral reefs and sustainable ecosystems generally. But the state of the natural environment has a crucial impact on the well-being, not only of the current generation, but of future generations too.

In the video podcast below, Professor Sir Partha Dasgupta, from the Faculty of Economics at the University of Cambridge and also from the University of Manchester, argues that the well-being of future generations requires an increase in the stock of capital per head, and that, in measuring this capital stock, we must take into account natural capital. In the paper to which the podcast refers, he argues “that a country’s comprehensive wealth per capita can decline even while gross domestic product (GDP) per capita increases and the UN Human Development Index records an improvement.”

Questions

  1. Why might a rise in GDP result in a decline in human well-being?
  2. In what sense is nature ‘over exploited’?
  3. What is meant by ‘comprehensive wealth’ and why might comprehensive wealth per capita decline even though the stocks of both manufactured capital and human capital are increasing?
  4. What is meant by ‘shadow prices’ in the context of natural capital?
  5. How might economists go about measuring the shadow prices of capital?
  6. What factors should determine the rate of discount chosen for projects that impact on the future state of the environment?
