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

  1. Why have crude oil prices fallen to their lowest level for 17 months?
  2. 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?
  3. Would a fall in inflation linked to a fall in commodity prices be a fall in cost-push or demand-pull inflation? Explain.
  4. What are the macroeconomic implications of the fall in crude oil prices?
  5. What factors are likely to have significant impact on crude oil prices in the coming months
  6. 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.)

With tight incomes, the first things that families tend to cut back on are the more luxury items. Extensions to houses are delayed, interior refurbishments are put off and the old car that was going to be traded in becomes something you can live with for another few years.

Car sales have been adversely affected during the recession, but data for May 2012 show a positive turn. Manufacturers have said that car sales are up by 7.9% compared with May last year. According to the Society of Motor Manufacturers and Traders (SMTT), much of the increased demand has come from private sales, where the increase has been over 14%.

This data may not be the answer to the economic troubles, but it is perhaps an indication that confidence is beginning to return. However, should things go from bad to worse in the eurozone, it isn’t hard to see data for the coming months showing the opposite trend. One other key piece of information to take from this data is the growth in the sales of lower-emissions vehicles. Sales of these were up 31.8% in May 2012 compared to the same time last year. Jonathan Visscher from SMMT said:

‘The green sector is growing fast…Every car manufacturer is going to have a hybrid model on its lists by the end of this year, even Ferrari.’

The continuing upward trend in car sales is by no means guaranteed to continue, especially with things like the expected rise in fuel duty later this year and the ongoing crisis in the eurozone, with Spanish banks potentially looking for help via a bail-out in the not too distant future. The following articles consider the acceleration in car sales.

  2. How could an increase in car sales benefit the economy? How could the multiplier effect have an impact?
  3. Which factors have contributed towards the growth in low-emissions cars?
  4. Sales of low-emissions cars have significantly increased. However, why is this increase
  5. What are some of the key things that can help to bring a recession to an end? Into which general category would you place this increase in car sales?
  6. Fuel duty is expected to rise later this year. How might this affect the number of new car registrations? What does your answer tell you about the cross elasticity of demand?

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 recent post on this blog referred to what sounds a fascinating new book, What Money Can’t Buy: The Moral Limits Of Markets, by Michael Sandel. The Guardian also recently featured an extract from this book.

As the earlier blog post discussed, our lives are now dominated by markets. Economists typically believe markets are the best way to allocate resources as, if the market mechanism works correctly, the resulting equilibrium maximizes economic welfare as measured by the sum of consumer and producer surplus. In particular, all consumers that are willing to pay a price above the market price are able to buy the product.

Fundamental to the measurement of consumer welfare is the notion that consumers will be prepared to buy a product as long as their willingness to pay exceeds the price. It therefore follows that consumers are more likely to buy the product as the price falls and, if they do so, gain increasing surplus. However, the extract from Michael Sandel’s book provides a number of interesting examples which suggest that in some situations this might not be the case.

One example concerns the storage of nuclear waste in Switzerland. When surveyed, 51% of the residents of the small Swiss village of Wolfenschiessen, said that they would be prepared to accept the waste being stored nearby. However, somewhat surprisingly, this figure fell to 25% when the residents were told that they would be compensated for the inconvenience. Furthermore, the figure remained at this low level even when the proposed compensation was increased to over £5000 per person.

Sandel argues that this is because, once compensation is introduced, financial incentives crowd out public spirit. He suggests that:

putting a price on the good things in life can corrupt them.

For economists, this potentially has important implications for how we evaluate market outcomes and our belief that the market equilibrium is always the optimal outcome. Furthermore, it suggests that in some circumstances allowing the market mechanism to allocate resources may not be the ideal solution.
