Oil prices have been falling in recent months. By early June they had reached a 17-month low. The benchmark US crude price (the West Texas Intermediate price) fell to $83.2 at the beginning of the month, and Brent Crude (the North Sea reference price for refining into petrol) fell to $97.7 (see chart). (For a PowerPoint of the chart below, click here.)
At the same time various commodity prices have also been falling. The IMF all commodities price index has fallen by 7.2% over the past 12 months and by 6.2% in May alone. Some commodities have fallen much faster. In the 12 months to May 2012, natural gas fell by 44%, wheat by 25%, lamb by 37%, Arabica coffee by 36%, coconut oil by 45%, cotton by 47%, iron ore by 23% and tin by 29%.
Although part of the reason for the fall in the price of some commodities is increased supply, the main reason is weak world demand. And with continuing problems in the eurozone and a slowdown in China and the USA, commodity price weakness is likely to continue.
So is this good news? To the extent that commodity prices feed through into consumer prices and impact on the rate of inflation, then this is good news. As inflation falls, so central banks will be encouraged to make further cuts in interest rates (in the cases where they are not already at a minimum). For example, the Reserve Bank of Australia cut its cash rate last week from 3.75% to 3.5%. This follows on from a cut from 4.25% on 1 May. In cases where there is no further scope for interest rate cuts (e.g. the US Federal Reserve Bank, whose interest rate is between 0% and 0.25%), then the fall in inflation may encourage a further round of quantitative easing.
But falling commodity prices are also a reflection of bad news, namely the low economic growth of the world economy and fears of turmoil from a possible Greek exit from the euro.
Update
A day after this was written (9/6/12), a deal was agreed between eurozone ministers to provide support of up to €100 billion for Spanish banks. This helped to reduce pessimism about the world economy, at least temporarily. Stock markets rose and so too did oil prices, by around 1%. But if pessimism increases again, then the fall is likely to resume.

Questions
- Why have crude oil prices fallen to their lowest level for 17 months?
- How can the concepts of income elasticity of demand, price elasticity of supply and price elasticity of demand help to explain the magnitude of the fall in crude oil prices?
- Would a fall in inflation linked to a fall in commodity prices be a fall in cost-push or demand-pull inflation? Explain.
- What are the macroeconomic implications of the fall in crude oil prices?
- What factors are likely to have significant impact on crude oil prices in the coming months
- Why is it difficult to predict crude oil prices over the coming months?
If one person saves more, then it will increase that person’s consumption possibilities in the future. If, however, everyone saves more, and hence spends less, then businesses will earn less and are likely to respond by producing less if the decline in aggregate demand continues. Hence if a country saves more, people could be worse off. That’s the paradox of thrift.
There is considerable debate around the world at the moment about the desirability of austerity policies. The debate has become more intense with the worsening economic outlook in many European countries and with the election in France of François Hollande who rejects many of the austerity measures of his predecessor, Nicolas Sarkozy.
But can further stimulus be given to aggregate demand without causing a further worsening of countries’ public-sector debt positions and causing a fall in confidence in financial markets? And how would that impact on investment?
And in the meantime, as the economic outlook darkens, people are trying to save more, despite low interest rates. The paradox of thrift seems to be getting more acute. (Click here for a PowerPoint of the chart.)

Paul Volcker was Chair of the US Federal Reserve from 1979 to 1987. He was also Chair of the Economic Recovery Advisory Board under President Barack Obama from February 2009 to January 2011. In the webcast and articles below, he reflects on the current state of the world financial system – from regulation, to the euro crisis, to world imbalances, to the system of floating exchange rates.
He argues that global financial systems are vulnerable to breakdowns. What is needed is reform to the system, and for that there needs to be consensus by politicians, regulators and central banks.
But, in the absence of international consensus on some key points, reform will be greatly weakened, if not aborted. The freedom of money, financial markets and people to move – and thus to escape regulation and taxation – might be an acceptable, even constructive, brake on excessive official intervention, but not if a deregulatory race to the bottom prevents adoption of needed ethical and prudential standards.
Perhaps most important is a coherent, consistent approach to dealing with the imminent failure of “systemically important” institutions. Taxpayers and governments alike are tired of bailing out creditors for fear of the destructive contagious effects of failure – even as bailouts encourage excessive risk-taking.
According to Volcker, countries must be prepared to surrender some sovereignty. Policies must be co-ordinated internationally and there must be stronger regulation by international bodies, such as the IMF and stronger concerted action by global organisations, such as the G20.
Left to their own devices, in an era of floating exchange rates, countries may pursue policies that exacerbate global imbalances.
Not so long ago, we were comforted by theorising that floating exchange rates would mediate international adjustments in a timely and orderly way. But, in the real world, many countries, particularly but not limited to small, open economies, simply find it impractical or undesirable to permit their currency to float.
We are left with the certainty, however awkward, that active participation in an open world economy requires some surrender of economic sovereignty. Or, to put the point more positively, it requires a willingness to co-ordinate policies more effectively.

A bumper olive crop in Spain would seem to be good news for Spanish olive growers. But the effect has been a fall in the prices of olives and olive oil. With 43% of the global supply, Spain is the world’s largest olive oil producer and changes in Spanish output have a big effect on the world price.
Premium extra virgin olive oil has fallen to its lowest level (even in nominal terms) since 2002. Today the price is around $2900 (£1850) a tonne in the wholesale market; in May 2006 it peaked at nearly $5854 – double today’s price.
And while this is bad news for Spanish farmers, for farmers in countries without bumper harvests, the low prices are even harder to bear.

The problem is being exacerbated by a fall in demand in many countries currently suffering recession, such as Greece, Portugal and Italy – all big olive oil consumers. Although olive oil prices have fallen, it is still more expensive than various substitutes. Many people are thus buying these cheaper alternatives, such as sunflower oil, especially for cooking.
What is more, cheaper substitutes for olive oil are increasing in supply. Take the case of rape seed oil in the UK. As the Mail Online article, linked to below, reports:
“UK rape planting is thought to have hit an all-time high this year as British farmers take advantage of the high prices being demanded for rapeseed – base ingredient of many vegetable oils and other edible oils.
Much of the UK crop is used by the local food industry, although some analysts are predicting strong UK yields will give farmers the opportunity to export more to Europe. Because of rising export demand, oil users in the UK claim there is little to indicate the price they are paying for rapeseed oil will drop substantially in the near future.”
The market for olive oil is global. Crop yields in one part of the world, both of olives and of substitute crops, affect global prices and hence growers’ incomes worldwide.

Countries differ considerably in terms of the number of hours people work.
Despite the criticisms levelled at Greece, with some claiming that Greek workers are ‘lazy’, according to 2010 figures, the average worker in Greece worked 2109 hours per year – more than in any other European country. The average German worker worked 1419 hours and the average Dutch worker only 1377.
Internationally, amongst developed countries, Korea has the highest number of working hours per worker at 2193 per year. In the USA, the figure is 1778 hours and in the UK it’s 1647. (Click on chart below for a larger version.)
But working long hours does not mean working more productively. Generally the countries in which people work longer hours have lower output per hour.
The following podcast and articles look at the relationship between hours worked and productivity and consider which way the causality lies. They also look at related issues such as the proportion of part-time working and the length of annual paid holidays.
