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.

Most students have a student loan: you need it to live; to buy text books; to survive. So, what do you do if your student loan hasn’t appeared in your bank account? This is a problem that many students have been facing. The Student Loans Company said that even after most courses had started, 175,358 students had still not had their loan application processed. This represented 16% of applications. There are various reasons given for this delay, but one that appears more often is the current economic downturn. This has been a crucial factor in so many students being without the necessary finance to begin university. Another reason is that many documents have been misplaced. On the other hand, a spokesman for the Student Loans Company (SLC) said that actually delays this year were no worse than in previous years, even though this is the first year when students applied directly to the SLC. Does this suggest that actually the whole system of student loans is still inefficient and needs to be overhauled again? Is there a better method?

In order to help students, many universities have made emergency payments to those without their loans. What’s the opportunity cost of this money? Surely it could be used for other purposes. Universities have seen their highest ever number of applications, although there has been a drop in Scottish student numbers and there are suggestions that tuition fees will increase again. What are the implications of the problems with student loans and the massive increase in university applications?

Questions

  1. Why has the recession had an impact on university applications?
  2. Should universities be able to set their own fees? What are the advantages and disadvantages of such a system? How could fees be determined?
  3. Primary and Secondary education is a merit good and free in the UK. What do we mean by a merit good and how can we illustrate the positive externalities associated with education? Why is higher education not free to the student? Aren’t there positive externalities associated with it?
  4. If tuition fees increase, student debt levels after graduation will be higher. What is the likely impact of this on the students themselves and on the economy?
  5. What the likely consequences for (a) students (b) universities of the delays in student loans?

A report from Cycling England has suggested that a £70m investment in cycling each year could save the government £520m per year. The savings result from the positive benefits of increased cycling – lower carbon dioxide emissions and lower NHS costs as we become healthier. But, do the numbers add up?

Investment in cycling could save £520m, government told Guardian (17/9/07)

Questions

1. Define the terms (i) external benefits (ii) external costs and (iii) marginal social benefit.
2. Identify three external benefits that result from increased cycling.
3. Using diagrams as appropriate, show how the market equilibrium and the socially optimum level of cycling will differ.
4. Discuss policies that the government could adopt to move the market closer to the social optimum.
