Rail companies will be permitted to raise average regulated rail fares next year by 6.2%. Not surprisingly, this has been met with dismay and anger by rail travellers, especially long-distance commuters, who could see their annual season tickets going up by several hundred pounds.

Some fares, such as advance tickets, are unregulated. Others, such as anytime, off-peak and season tickets, are regulated by the government. The formula for working out permitted price rises for regulated fares is RPI plus 3%, where RPI is the July annual inflation rate based on the retail price index.

The RPI figure was announced by the ONS on 14 August and was a surprisingly high 3.2% – up from 2.8% in June: see Table 21 in the ONS’s CPI And RPI Reference Tables, July 2012. (Click here for a PowerPoint of the chart on the left.) Hence average fares can rise by 3.2% + 3% = 6.2%.

Rail travellers are angry on three counts:

First, the RPI measure of inflation is generally around 0.5% higher than the CPI measure (which is used for working out public-sector pay increases and the uprating of pensions and benefits). The July figure for CPI inflation was 2.6%.

Second, the extra 3% added on top of RPI means that that rail fares are going up more rapidly than other prices, and incomes too. The reason given for this is to shift the burden of funding the railways from the taxpayer to the traveller.

Third, the formula applies to average fares. Rail companies can raise particular regulated fares by up to 5 percentage points more than the formula provided they raise other fares by less than the formula. Thus some fares are set to rise by 11.2% – including some of the most expensive season tickets.

The government justified the increases by arguing that the higher fares will allow more investment by the rail companies, which could result in lower costs in the future. Nevertheless, two thirds of the revenue from the above-inflation increases will go to the government and only one third to the rail companies.

Questions

  1. What are the arguments for and against the general principle of using an RPI+X formula for regulating rail fares?
  2. What are the arguments for and against allowing train operating companies to raise regulated rail fares by an average of RPI plus 3%, with 2 of the 3 percent above RPI inflation going to the government?
  3. In what ways are travellers likely to respond to the higher prices?
  4. Why are some travellers likely to have a much lower price elasticity of demand for rail travel than others? What determines this price elasticity of demand?
  5. What externalities exist in rail transport? How should this impact on the government’s rail pricing strategy?
  6. How is infrastructure development funded for (a) rail, (b) roads and (c) airports? Does this lead to an efficient allocation of transport investment?
  7. How does rail pricing in the UK compare with that in other European countries? Should other European countries follow the UK’s policy of above inflation fare increases to fund rail investment?

A campaign to introduce a tax on disposable plastic bags in England has been launched by various pressure groups, including The Campaign to Protect Rural England (CPRE), Keep Britain Tidy, the Marine Conservation Society and Surfers Against Sewage. Plastic bags, they maintain, litter streets and the countryside and pollute the seas, where they cause considerable damage to marine life.

They propose a tax of 5p per bag, which would be passed on to consumers. Such a levy has already been introduced in Wales in October 2011. As a result, plastic bag use in Wales has dropped dramatically (see also the full report from the Welsh Government). The Scottish Government and the Northern Ireland Assembly are also planning introducing similar charges.

Many other governments have introduced taxes, charges or bans on plastic bags and many more are considering introducing such measures. Ireland introduced a 15 euro cent charge on single-use plastic bags as far back as 2002 and saw a 94% reduction in plastic bag use (328 per person per year to 21). The charge was raised to 22 euro cents in 2007 after bag use rose to 30 per person.

Other countries have banned plastic bags altogether: some, such as Rwanda and Somalia have banned all plastic bags; others, such as China and South Africa have banned very thin bags; others, such as Italy, have banned non-biodegradable ones.

In the USA, various states or districts have introduced levies and in the EU, where more than four billion bags are thrown away each year, the European Commission will soon publish proposals for limiting the use of plastic bags.

So what are the arguments for limiting the use of plastic bags? Why is it not enough to leave things simply to the market? And if the use of plastic bags is to be reduced, what’s the most efficient way of doing so? Are there any problems with alternatives to plastic bags? The following articles and reports consider these questions?

Barclays’ Chief Executive, Bob Diamond, has resigned following revelations that Barclays staff had been involved in rigging the LIBOR in the period 2005–9, including the financial crisis of 2007–9.

So what is the LIBOR; how is it set; what were the reasons for Barclays (and other banks, as will soon be revealed) attempting to manipulate the rate; and what were the consequences?

The LIBOR, or London interbank offered rate, is the average of what banks report that they would have to pay to borrow from one another in the inter-bank market. Separate LIBORs are calculated for 15 different lending periods: overnight, one week, one month, two months, three months, six months, etc. The rates are set daily as the average of submissions made to Thomson Reuters by some 15 to 20 banks (a poll overseen by the British Bankers’ Association). Thomson Reuters then publishes the LIBORs, along with all of the submissions from individual banks which are used to calculate it.

Many interest rates around the world are based on LIBORs, or their European counterpart, EURIBORs. They include bond rates, mortgage rates, overdraft rates, etc. Trillions of dollars worth of such assets are benchmarked to the LIBORs. Thus manipulating LIBORs by even 1 basis point (0.01%) can result in millions of dollars worth of gains (or losses) to banks.

The charge, made by the Financial Services Authority, is that Barclays staff deliberately under- or overstated the rate at which the bank would have to borrow. For example, when interbank loans were drying up in the autumn of 2008, Barclays staff were accused of deliberately understating the rate at which they would have to borrow in order to persuade markets that the bank was facing less difficulty than it really was and thereby boost confidence in the bank. In other words they were accused of trying to manipulate LIBORs down by lying.

As it was the LIBORs were rising well above bank rate. The spread for the one-month LIBOR was around 1 to 1.2% above Bank Rate. Today it is around 0.1 to 0.15% above Bank Rate. Without lying by staff in Barclays, RBS and probably other banks too, the spread in 2008 may have been quite a bit higher still.

The following articles look at the issue, its impact at the time and the aftermath today.

World leaders have been meeting in Rio de Janeiro at a United Nations Conference on Sustainable Development. The conference, dubbed ‘Rio+20’, refers back to the first UN Conference on Environment and Development (UNCED) held in Rio 20 years ago in June 1992.

The 1992 conference adopted an Agenda 21. It was “comprehensive plan of action to be taken globally, nationally and locally by organizations of the United Nations System, Governments, and Major Groups in every area in which human impacts on the environment.”

The 2012 conference has looked at progress, or lack of it, on sustainability and what needs to be done. It has focused on two major themes: “how to build a green economy to achieve sustainable development and lift people out of poverty, including support for developing countries that will allow them to find a green path for development; and how to improve international coordination for sustainable development.” Issues examined have included decent jobs, energy, sustainable cities, food security and sustainable agriculture, water, oceans and disaster readiness.

But just what is meant by sustainable development? The conference defines sustainable development as that which meets the needs of the present without compromising the ability of future generations to meet their own needs. “Seen as the guiding principle for long-term global development, sustainable development consists of three pillars: economic development, social development and environmental protection.”

The articles below look at prospects for national and global sustainability. They also look at a new measure of national wealth, the Inclusive Wealth Index (IWI). This index has been developed under the auspices of the International Human Dimensions Programme on Global Environmental Change (IHDP) and published in its Inclusive Wealth Report 2012 (see report links below).

The IWR 2012 was developed on the notion that current economic production indicators such as gross domestic product (GDP) and the Human Development Index (HDI) are insufficient, as they fail to reflect the state of natural resources or ecological conditions, and focus exclusively on the short term, without indicating whether national policies are sustainable.

The IWR 2012 features an index that measures the wealth of nations by looking into a country’s capital assets, including manufactured, human and natural capital, and its corresponding values: the Inclusive Wealth Index (IWI). Results show changes in inclusive wealth from 1990 to 2008, and include a long-term comparison to GDP for an initial group of 20 countries worldwide, which represent 72% of the world GDP and 56% of the global population. (Click on chart for a larger version.)

So will growth in IWI per capita be a better measure of sustainable development than growth in GDP per capita? The articles also consider this issue.

No market is perfect and when the market mechanism fails to deliver an efficient allocation of resources, we say the market fails and hence there is justification for some government intervention. From a monopolist dominating an industry to a manufacturing firm pumping out pollution, there are countless examples of market failure.

The Guardian is creating a guide to climate change, covering areas from politics to economics. The problem of climate change has been well documented and this blog considers a particular issue – the case for climate change or the environment as a market failure. In many cases just one market failure can be identified, for example an externality or a missing market. However, one of the key problems with climate change is that there are several market failures: externalities in the form of pollution from greenhouse gases; poor information; minimal incentives; the problem of the environment as a common resource and the immobility of factors of production, to name a few. Each contributes towards a misallocation of resources and prevents the welfare of society from being maximised.

When a market fails, intervention is justified and economists argue for a variety of policies to tackle the above failures. In a first-best world, there is only one market failure to tackle, but in the case of the environment, policy must be designed carefully to take into account the fact that there are numerous failings of the free market. Second-best solutions are needed. Furthermore, as the problem of climate change will be felt by everyone, whether in a developed or a developing country, international attention is needed. The two articles below are part of the Guardian’s ultimate climate change guide and consider a huge range of economic issues relating to the problem of environmental market failure.

Questions

  1. What is meant by market failure?
  2. What are the market failures associated with the environment and climate change? In each case, explain how the issue causes an inefficient allocation of resources and thus causes the market to fail? You may find diagrams useful!
  3. What is meant by the first-best and second-best world?
  4. What does a second-best solution aim to do?
  5. Using diagrams to help your explanation, show how a tax on pollution will have an effect in a first best world, where the only market failure is a negative externality and in a second best world, where the firm in question is also a monopolist.
  6. What solutions are there to the problem of climate change? How effective are they likely to be?
  7. Does the need to tackle climate change require international co-operation? Can you use game theory to help your explanation?!
