The price of road fuel is falling. Petrol and diesel prices in the UK are now at their lowest level since February 2011. The average pump price for a litre of unleaded petrol has fallen to 130.44p in November – down nearly 8p per litre since September.
According to the AA, the reduction in price equates to a fall in the average monthly expenditure on petrol of a two-car family of £14.49 – down from £252.54 to £238.05. This saving can be used for spending on other things and can thus help to boost real aggregate demand. The fall in price has also helped to reduce inflation.
But will lower fuel prices lead to a rise in fuel consumption? In other words, will some of the savings people make when filling up be used for extra journeys? If so, how much extra will people consume? This, of course depends on the price elasticity of demand.
The following articles explain why the price of road fuel has fallen and look at its consequences.

In market capitalism, the stock of manufactured capital provides a flow of output. The profitability of the use of that capital depends on the cost of investing in that capital and the cost of using it, and on the flow of revenues from that capital. Discounted cash flow techniques can be used to assess the profitability of a given investment in capital; the flows of costs and revenues are discounted at a market discount rate to give a net present value (NPV). If the NPV is positive (discounted revenues exceed discounted costs), the investment is profitable; if it is negative, the investment is unprofitable. (See Economics, 8th edition, section 9.3.)
There may be market imperfections in the allocation of investment, in terms of distorted prices and interest rates. These may be the result of market power, asymmetry of information, etc., but in many cases the market allows capital investment to be allocated relatively efficiently.
Natural capital
This is not the case with ‘natural capital’. Natural capital (see also) is the stock of natural resources and ecosystems that, like manufactured capital, yields a flow of goods and services into the future.
Natural capital, whilst it can be improved or degraded by human action, is available without investment. Thus the natural capital of the oceans yields fish, the natural capital of the skies yields rain and the natural capital of forests reduces atmospheric CO2.
Even though some natural capital is owned (e.g. private land), much is a common resource. As such, it is free to use and tends to get overused. This is the Tragedy of the Commons – see, for example, the following news items: A modern tragedy of the commons and Is there something fishy going on?.
Natural capital accounting
But would it be possible to give a value to both the stock of natural capital and the goods and services provided by it? Would this environmental accounting enable governments to tax or subsidise firms and individuals for their use or enhancement of natural capital?
On 21 and 22 November 2013, the first World Forum on Natural Capital took place in Edinburgh. This brought together business leaders, politicians, economists, environmentalists and other scientists to discuss practical ways of taking natural capital into account in decision making. Central to the forum was a discussion of ways of valuing natural capital, or ‘natural capital accounting’. As the forum site states:
Natural capital accounting is a rapidly evolving new way of thinking about how we value the economic benefits we derive from our natural environment. The World Forum on Natural Capital will bring together world-class speakers, cutting edge case studies and senior decision makers from different sectors, in order to turn the debate into practical action.

But if natural capital is not owned, how is it to be priced? How will the costs and benefits of its use be valued? How will inter-generational effects be taken into account? Will firms price natural capital voluntarily if doing so reduces their profits? Will firms willingly extend corporate social responsibility to include corporate environmental responsibility? Will governments be prepared to introduce taxes and subsidies to internalise the costs of using natural capital, even if the effects extend beyond a country’s borders? Will natural capital accounting measure purely the effects on humans or will broader questions of maintaining and protecting environmental diversity for its own sake be taken into account? These are big questions and ones that various organisations are beginning to address.
Despite problems of measurement and incentives, sometimes there are clear economic benefits from careful evaluation and management of natural capital. Julia Marton-Lefèvre is Director General of the International Union for Conservation of Nature (IUCN). According to the first Guardian article below:
Her favourite example of natural capital working in practice comes from Vietnam, where “planting and protecting nearly 12,000 hectares of mangroves cost just more than $1m but saved annual expenditures on dyke maintenance of well over $7m. And that only accounts for coast maintenance: mangroves are also nurseries for fish, meaning livelihoods for fishing and source of nutrients … “
One organisation attempting to value natural capital is The Economics of Ecosystems and Biodiversity project (TEEB). It also looks at what organisational changes are likely to be necessary for the management of natural capital.
Based on data collected from 26 early adopter companies (60% of them with $10 Billion+ revenues each) across several industry sectors this provides real life evidence on the drivers and barriers for natural capital management.
Pricing the environment is a highly controversial issue. Critics claim that the process can easily be manipulated to serve the short-term interests of business and governments. What is more, where tradable permits markets have been set up, such as the EU’s Emissions Trading Scheme (ETS), prices have often been a poor reflection of social costs and have been open to manipulation. As Nick Dearden, director of the World Development Movement (WDM), says:
It is deeply ironic that the same financial markets that caused the economic crisis are now seen as the solution to our environmental crisis. It’s about time we learnt that financial markets need to be reined in, not expanded. Pricing these common resources on which people depend for their survival leaves all of us more exposed to the forces of the global economy, and decisions about whether or not to protect them become a matter of accounting.
The measurement of natural capital and setting up systems to internalise the costs and benefits of using natural capital is both complex and a political minefield – as the following articles show.

The Conservatives have pledged that, if they win the next election, they will hold a referendum in 2017 on whether or not the UK should remain in the EU. The Prime Minister has also said that he will renegotiate the terms of UK membership and push for reforms to the EU to cut administrative costs, reduce intervention and make the EU more competitive. We are likely to be bombarded with arguments for and against membership over the coming months.
In a contribution to the debate, the CBI has just published research showing that membership of the EU benefits the UK by up to £78 billion per year – £3000 per household. It also conducted a poll of its members which shows that the vast majority (78%, including 77% of SMEs) want to remain part of the EU, believing that membership brings net benefits to their business and the economy more generally.
However, as the Director-General of the CBI, John Cridland, said:
But the EU isn’t perfect and there is a growing unease about the creeping extension of EU authority. Europe has to become more open, competitive and outward looking if we are to grow and create opportunities and jobs for all our citizens.
The following articles and documents look at the CBI’s arguments.

A bumper harvest should be good news for farmers – but not if it drives down prices. This is the position facing many Australian farmers. After a relatively wet summer a year ago and a mild winter this year, crop yields have soared. But the prices farmers can get in wholesale markets have been so low that many have resorted to setting up their own farm shops or selling in farmers’ markets or from the backs of ‘utes’ (utility vehicles, i.e. pickup trucks) or at roadside stalls.
And the supply problem is not just one of increased domestic supply: cheap food imports, often of inferior quality, have been flooding into Australia. Increasing food exports,
especially to Asia, would help Australian farmers, but here again there is competition in these markets from other countries.
The problem of increased Australian supply is even more serious for Australian farmers in areas where harvests have not been so good. Australia is a huge country and conditions, although generally favourable this year, have been poor in some areas. Here farmers face the double disaster of low output and low prices.
Australian dairy farmers too are facing problems of falling prices. Price deregulation and the monopsony power of supermarkets have driven down
the price of milk and other dairy products. Since deregulation in 2000, the number of dairy farms has halved, as many smaller family farms go out of business and larger ‘industrial-scale’ farms grow.
So are there any solutions? The BBC article looks at things being done in Tasmania to help small farmers, but questions whether small farmers have much of a future more generally in Australia?

Each year in November, the Living Wage Foundation publishes figures for the hourly living wage that is necessary for people to meet basic bills. The rate for London is calculated by the Greater London Authority and for the rest of the UK by the Centre for Research in Social Policy at Loughborough University.
The 2013 update was published on 4 November. The Living Wage was estimated to be £8.80 in London and £7.65 in the rest of the UK.
Two things need to be noted about the Living Wage rate. The first is that the figure is an average and thus does not take into account the circumstances of an individual household. Clearly households differ in terms of their size, the number of wage earners and dependants, the local costs of living, etc. Second, the figures have been reduced from what is regarded as the ‘reference’ living wage, which is estimated to be £9.08 outside London. The reason for this is that people earning higher incomes have seen their living standards squeezed since 2009, with prices rising faster than average post-tax-and-benefit wages. Thus, the Living Wage is capped to reflect the overall decline in living standards. As the Working Paper on rates outside London explains:
From 2012 onwards, two kinds of limit have been put on the amount that the Living Wage as applied can rise in any one year. The first limits the increase in the net income (after taxes and benefits) requirement for each household on which the living wage calculation is based, relative to the rise in net income that would be achieved by someone on average earnings. The second limits the increase in the living wage itself (representing gross income) relative to the increase in average earnings.
Nevertheless, despite this capping of the living wage, it is still significantly higher than the UK National Minimum Wage, which currently stands at £6.31 for those aged 21 and over. This can be seen from the chart (click here for a PowerPoint).
Paying the Living Wage is voluntary for employers, but as The Guardian reports:
A total of 432 employers are now signed up to the campaign, up from 78 this time last year, including Legal & General, KPMG, Barclays, Oxfam, Pearson, the National Portrait Gallery and First Transpennine Express, as well as many smaller businesses, charities and town halls. Together they employ more than 250,000 workers and also commit to roll out the living wage in their supply chain.
But as The Observer reports:
The number of people who are paid less than a ‘living wage’ has leapt by more than 400,000 in a year to over 5.2 million, amid mounting evidence that the economic recovery is failing to help millions of working families.
A report for the international tax and auditing firm KPMG also shows that nearly three-quarters of 18-to-21-year-olds now earn below this level – a voluntary rate of pay regarded as the minimum to meet the cost of living in the UK. The KPMG findings highlight difficulties for ministers as they try to beat back Labour’s claims of a “cost of living crisis”.
According to the report, women are disproportionately stuck on pay below the living wage rate, currently £8.55 in London and £7.45 elsewhere. Some 27% of women are not paid the living wage, compared with 16% of men. Part-time workers are also far more likely to receive low pay than full-time workers, with 43% paid below living-wage rates compared with 12% of full-timers.
But although paying a living wage may be desirable in terms of equity, many firms, especially in the leisure and retailing sectors, claim that they simply cannot afford to pay the living wage and, if they were forced to, would have to lay off workers.
The point they are making is that it is not economical to pay workers more than their marginal revenue product. But this raises the question of whether a higher wage would encourage people to work more efficiently. If it did, an efficiency wage may be above current rates for many firms. It also raises the question of whether productivity gains could be negotiated in exchange for paying workers a living wage
These arguments are discussed in the following podcast.

Questions
- How is the Living Wage calculated?
- What are the reasons for announcing a Living Wage figure that is lower than a reference living wage? Assess these reasons.
- If there are two separate figures for the Living Wage for London and the rest of the UK, would it be better to work out a living wage for each part, or even location, of the UK?
- Why might it be in employers’ interests to pay at least the Living Wage? Does this explain why more and more employers are volunteering to pay it?
- Assess the Labour Party’s pledge, if they win the next election, that ‘firms which sign up to the living wage will receive a tax rebate of up to £1000 for every low-paid worker who gets a pay rise, funded by tax and national insurance revenue from the higher wages’.
- Which is fairer: to pay everyone at least the Living Wage or to use tax credits to redistribute incomes to low-income households?
