European wine producers have seen one of the worst grape harvests for decades. With exceptionally wet weather in the northern European growing areas and exceptionally hot and dry weather in the southern ones, yields are well down in most countries.

In France, the world’s largest wine producer, wine production is forecast to be 19% down on the previous year. In Italy and Spain, Europe’s second and third largest producers, production is forecast to be 3% and 6% down respectively. Production in the EU as a whole, which produces some 57% of world output, is expected to be 9% down and at a historically low level. What is more, the past five years in the EU have all seen modest harvests.

And the poor harvests are not confined to Europe. Argentina’s production is some 24% down on 2011, with New Zealand’s 17% down. And despite a few countries expecting an increase, including the USA and Chile, overall world production is expected to be 6% down on 2011 and more than 7% down on the average for 2008–11.

So is this good news or bad? At first sight it would seem to be bad, especially for the countries with large falls in output. It would also seem to be bad news for the consumer, with prices set to rise.

But for some it’s good news. If prices rise, then producers experiencing an increase in output will have a double gain. And a fall in output is only part of the story. For some producers, the smaller yield has been accompanied by an increase in quality. And then there’s the question of stocks. For several years, global production of wine has exceeded consumption. Indeed the gap widened after the financial crisis and recession of 2007–9 as consumption of wine fell. This year’s poor global harvest should help to slow down the increase in stocks or may even lead to a reduction in stocks, depending on the extent to which demand recovers.

10 of the 17 eurozone countries have agreed to adopt a financial transactions tax (FTT), often known as a ‘Tobin tax’ after James Tobin who first proposed such a tax back in 1972. The European Commission has backed the proposal, which involves levying a tax of 0.1% on trading in bonds and shares and 0.01% on trading in derivatives.

The 10 countries, France, Germany, Austria, Belgium, Greece, Italy, Portugal, Slovakia, Slovenia and Spain, and possibly also Estonia, hope to raise billions of euros from the tax, which will apply whenever at least one of the parties to a trade is based in one of the 10 (or 11) countries.

On several occasions in the past on this site we’ve examined proposals for such a tax: see, for example: Pressure mounts for a Tobin tax (update) (Nov 2011), A ‘Robin Hood’ tax (Feb 2010), Tobin or not Tobin: the tax proposal that keeps reappearing (Dec 2009) and A Tobin tax – to be or not to be? (Aug 2009). Tobin taxes are also considered in Economics (8th ed) (section 26.3) and Economics for Business (5th ed) (section 32.4).

As we noted last year in the blog Is the time right for a Tobin tax?, the tax is designed to be too small to affect trading in shares or other financial products for purposes of long-term investment. It would, however, dampen speculative trades that take advantage of tiny potential gains from very short-term price movements. Such trades account for huge financial flows between financial institutions around the world and tend to make markets more volatile. The short-term dealers are known as high-frequency traders (HFTs) and their activities now account for the majority of trading on exchanges. Most of these trades are by computers programmed to seek out minute gains and respond in milliseconds. And whilst they add to short-term liquidity for much of the time, this liquidity can suddenly dry up if HFTs become pessimistic.

Supporters of the tax claim that it will make a major contribution to tackling the deficit problems of many eurozone countries. Critics claim that it will dampen investment and growth and divert financial business away from the participating countries. The following articles look at the arguments.

  5. How does a financial transactions tax differ from the UK’s stamp duty reserve tax?
  6. Explain why the design of the stamp duty tax has prevented the flight of capital and trading from London. Could a Tobin tax be designed in such a way?

Induced hydraulic fracturing or “fracking”, is a technique used to make fractures in shale beds, normally deep underground, through the injection of liquids under high pressure. The idea is to release oil or gas. Fracking has transformed the oil industry by allowing vast reserves to be tapped.

Although the main ingredient of the fracking liquid is water, it is also necessary to include sand and a gelling agent to increase the viscosity of the liquid and bind in the sand. The commonest gelling agent is guar gum, a gel made from powdered guar seeds, which are grown in the semi-desert regions of India and Pakistan. Guar gum is also widely used in the food industry as a binding, thickening, texturising and moisture control agent.

With the rapid growth in fracking, especially in the USA, the demand for guar gum has rocketed – and so has its price. In just one year the price of guar beans, from which the seeds are extracted, has risen ten fold from about 30 rupees (about 34 pence) to around 300 rupees per kilo. This has transformed the lives of many poor farmers. Across the desert belt of north-west India, fields are being planted with guar.

But will it last? What will the oil and gas extraction companies do in response to the higher price? What will the food industry do? What will happen to the demand and supply of guar gum over the longer term? Is it risky for farmers in India and Pakistan to rely on a single crop, or should they take advantage of the high prices while they last? These types of questions are central to many mono-crop economies.

With droughts and poor harvests in both North America and in Russia and the Ukraine, there are worries that food prices are likely to see sharp rises in the coming months. This is clearly bad news for consumers, especially the poor for whom food accounts for a large proportion of expenditure.

But it’s also bad news more generally, as higher food prices are likely to have a dampening effect on the global economy, struggling to recover from five years of low or negative growth. And it’s not just food prices. Oil prices are rising again. Since mid June, they have risen by nearly 25%. This too is likely to have a dampening effect.

Another contributing factor to rising food prices is a response, in part, to rising oil prices. This is the diversion of land from growing food to growing crops for biofuels.

G20 countries held a conference call on 28 August to discuss food prices. Although representatives decided against an emergency meeting, they agreed to reassess the situation in a few weeks when the size of the US harvest would be clearer. If the situation proved as bad as feared, then the G20 would call an emergency meeting of the Rapid Response Forum, to consider what could be done.

But is the sole cause of rising food prices a lack of production? Are there other problems on the supply side, such as poor distribution systems and waste? And what about the role of demand? How is this contributing to long-term increases in food prices? The articles consider these various factors and what can be done to dampen food prices.

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.
