Economics studies the choices people make. ‘Rational choice’ involves the weighing up of costs and benefits and trying to maximise the surplus of benefits over costs. This surplus will be maximised when people do more of things where the marginal benefit exceeds the marginal cost and less of things where the marginal cost exceeds the marginal benefit. But, of course, measuring benefits and costs is not always easy. Nevertheless, for much of the time we do make conscious choices where we consider that choosing to do something is ‘worth it’: i.e. that the benefit to us exceeds the cost.
When we make a choice, often this involves expenditure. For example, when we choose to buy an item in a shop, we spend money on the item, and also, perhaps, spend money on transport to get us to the shop. But the full opportunity cost includes not only the money we spend, but also the best alternative activity sacrificed while we are out shopping.
Then there are the benefits. Not all pleasurable activity costs us money. The sight of beautiful contryside or the pleasure of the company of friends may cost us very little, if anything, in money terms. But they may still be very valuable to us.
If we are to make optimal decisions we need to have some estimate of all costs and benefits, not just ones involving the payment or receipt of money. This applies both to individual behaviour and to collective decisions made by governments or other agencies.
Cost–benefit analysis seeks to do this to help decisions about new projects, such as a new road, a new hospital, environmental projects, and so on. But just how do we set about putting a value on the environment – on the pleasure of a walk in bluebell woods, on protecting bird life in wetlands or sustaining ecosystems?
For the first time there has been a major study that attempts to value the environment. According to the introduction to the report:
The UK National Ecosystem Assessment (UK NEA) is the first analysis of the UK’s natural environment in terms of the benefits it provides to society and the nation’s continuing prosperity. Carried out between mid-2009 and mid-2011, the UK NEA has been a wide-ranging, multi-stakeholder, cross-disciplinary process, designed to provide a comprehensive picture of past, present and possible future trends in ecosystem services and their values; it is underpinned by the best available evidence and the most up-to-date conceptual thinking and analytical tools. The UK NEA is innovative in scale, scope and methodology, and has involved more than 500 natural scientists, economists, social scientists and other stakeholders from government, academic and private sector institutions, and non-governmental organisations (NGOs).
The following podcast and webcast look at the report and at some of the issues it raises in terms of quantifying and incorporating environmental costs and benefits into decision taking.

Questions
- How would you set about valuing the benefits of woodlands?
- According to the report, the health benefits of living close to a green space are worth up to £300 per person per year. How much credance sould we attach to such a figure?
- What do you understand by the ‘ecosystem approach’ and the term ‘ecosystem services’?
- Explain Figure 2 on page 3 of Chapter 2 of the report.
- Should decision makers quantify only those benefits of ecosystems experienced by humans? Would all environmentalists agree with this approach?
- What are the advantages and disadvantages of quantifying all costs and benefits in money terms?
- Compare the consequences over the next 50 years of a ‘world markets’ scenarios with that of a ‘nature at work’ scenario.
- What policy implications follow from the report?
Inequality is growing in most countries. This can be illustrated by examining what has been happening to countries’ Gini coefficient. The Gini coefficient measures income inequality, where 0.00 represents perfect equality, with everyone in the country earning the same, and 1.00 represent perfect inequality, with one person earning all the country’s income. (Note that sometimes it is expressed as the ‘Gini index’, with 100 representing perfect inequality). In virtually all countries, the Gini coefficient has been rising. In the OECD countries it has risen by an average of 0.3% per annum over the past 25 years. The OECD average is now 0.31.
But despite the fact that the Gini coefficient has been rising, its value differs markedly from one country to another, as does its rate of change. For example, Finland’s Gini coefficient, at 0.26, is below the average, but it has been rising by 1.2% per annum. By contrast, Turkey’s Gini coefficient, at 0.41, is above the average and yet has been falling by 0.3% per annum.
The most unequal of the developed countries is the USA. According to OECD data, its Gini coefficient is 0.38, well above the values in the UK (0.34), Japan (0.33), Germany (0.30) France (0.29) and Denmark (0.26). What is more, inequality in the USA has been increasing by an average of 0.5% per annum since the mid 1980s.
According to the United Nations’ Human Development Report 2010, the USA’s Gini coefficient is even higher, at 0.41 (see Table 3 of the report). But this is still below that of Russia, with a figure of 0.44, a figure that has markedly worsened over time, along with those of other former Soviet countries. According to the report (page 72):
The worsening is especially marked in countries that were part of the former Soviet Union – which still have relatively low Gini coefficients because they started with low inequality. Transition has eroded employment guarantees and ended extensive state employment. Before the fall of the Berlin Wall, 9 of 10 people in socialist countries were employed by the state, compared with 2 of 10 in Organisation for Economic Co-operation and Development economies. While the privileged elite (the nomenklatura) often attained higher material well-being, the measured differences in income were narrow.
The Gini coefficient for Russia is the same as the average of the 39 developing countries with the lowest level of human development &nbash; and developing countries are generally much less equal than developed ones. Of course, some developing countries have an even higher Gini coefficient: for Angola the figure is 0.59; for Haiti it is 0.60.

The Greek economy is suffering. In April 2010, a €45 billion bailout package was agreed between Greece and the IMF and the EU. This was increased to €110 billion in May 2011. (The bailout loans expire in 2013.) In return for the loans, Greece agreed to tough austerity measures, involving tax increases, clamping down on tax evasion and government expenditure cuts. These measures have succeeded in cutting the deficit by 5 percentage points, but it still stood at 10.5% of GDP in 2010. Public-sector debt rose from 127% of GDP in 2009 to 143% in 2010. The market cost of borrowing on two-year government bonds currently stands at 23% per annum – a sign of a serious lack of confidence by investors in Greece’s ability to repay the loans.
The austerity measures have brought great hardship. Unemployment has soared. In February 2011, it reached 15.9%; in February last year it was 12.1%. According to the IMF’s World Economic Outlook (Table A2), Greek real GDP fell by 2.0% in 2009, by 4.5% in 2010 and is forecast to fall by 3.0% in 2011. But with GDP falling, this brings automatic fiscal stabilisers into play: lower incomes mean lower income tax revenues; lower expenditure means lower VAT revenue; higher unemployment means that more people claim unemployment-related benefits. This all makes it harder to meet the deficit reduction targets through discretionary tax rises and government expenditure cuts and makes it even more important to cut down on tax evasion. But, of course, the more taxes rise and the more government expenditure is cut, the more this suppresses aggregate demand. The austerity measures have thus worsened the recession.
On May 9, the ratings agency Standard & Poor’s downgraded Greece’s rating to B (15 points below the top rating of AAA and 6 points into ‘junk’ territory). It now has the lowest rating in Europe along with Belarus.
Worries have been growing that Greece might be forced to default on some its debt, or choose to do so. This would probably mean an extension of repayment periods. In other words, bondholders would be paid back in full but at a later date. This has been referred to as ‘debt re-profiling’. This could cause a renewed loss of confidence, not only in the Greek economy, but also in banks that are major lenders to Greece and which would be exposed in the case of default or restructuring.
The IMF and the ECB have been quick to stress that Greece can continue to manage its debt and that, if necessary, another loan might be negotiated. Anticipations are that Greece could indeed ask for a further bailout. But is this the answer? Or would it be better if Greece sought a restructuring of its debt? The following webcasts and podcasts consider the issue.

The Chancellor of the Exchequer, George Osborne, delivered the annual Budget on 23 March. He was very keen to have a ‘Budget for growth’ given the pessimism of consumers (see Table 1, UK, line 3, in Business and Consumer Survey Results, February 2011) and the bad news on inflation (see 4.4% and rising?).
But what could he do? Despite being urged by the Labour opposition to stimulate aggregate demand by cutting the deficit more slowly, he ruled out this alternative. It would be perceived by markets, he argued, as a sign that he was ‘gong soft’ on the commitment to tackle the deficit.
If stimulating aggregate demand directly was out, the alternative was to use supply-side policy: to provide more favourable conditions for business by cutting ‘red tape’, providing tax incentives for investment, reducing regulations, simplifying tax, cutting corporation tax financed by tax increases elsewhere, creating 21 ‘enterprise zones’ and funding extra apprenticeships and work experience placements.
The links below give details of the measures and consider their likely effectiveness. Crucially, the Budget will be much more successful in encouraging investment if people think it will be successful. In other words, its success depends on how it affects people’s expectations. Will it help confidence to return – or will the impending tax increases and cuts on government expenditure only make people more pessimistic?

Are we heading for ‘perfect storm’ in commodity production and prices? Certainly the prices of many commodities have soared in recent months. These include the prices of foodstuffs such as dairy products, cooking oils and cereals, crude oil, cotton, metals and many other raw materials. The overall world commodity price index has risen by 28% in the past 12 months. The following are some examples of specific commodities:
Price rises in the 12 months to February 2011
• Wheat 62%
• Maize 59%
• Coffee 70%
• Beef 39%
• Sugar 46%
• Palm kernal oil 142%
• Soybean oil 50%
• All food price index 32%
• Crude oil 20%
• Cotton 132%
• Fine wool 55%
• Softwood timber 25%
• Iron ore 78%
• Copper 29%
• Tin 55%
• All metals index 58%
• Rubber 79%.
The problems are both short term and long term, and on both the demand and supply sides; and the effects will be at micro, macro and global levels. Some hard choices lie ahead.
The following webcast, articles and reports explore both the current position and look into the future to ask whether rising commodity prices are likely to continue or even accelerate.
The first link is to a BBC World Debate which considers the following issues: “Is scarcity of natural resources a serious challenge for developing and advanced economies? How great is the risk that scarcity might lead to conflict, both within and between nations? Might a scramble for resources lead to a retreat from globalisation and to greater protectionism?”
