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.

For some people, a pint of beer is a regular thing each week. Add all your pints of beer together, then add your friend’s pints, their friends’ pints and … you get the idea. Once you’ve done that for the entire population, you have an estimate of total beer consumption in the UK. This can then be compared with total consumption of beer in other countries and between continents.
Prior to 2007, Europe and the Americas were the biggest beer drinking continents, but since then, Asia has emerged as the leader of pints of beer consumed, drinking 67bn litres of beer compared with the Americas’ 57bn and Europe’s 51bn in 2011. In per capita terms, Asia is still some way off, with Japan leading the way as the highest Asian country in 41st place, consuming 64 litres of beer per year per capita of the population. So how is this relevant to economics and business?
Consumption of anything provides jobs – bar workers, manufacturers and in the case of beer, probably law enforcement! It probably also increases utility – after all, why consume it if it’s not going to give you some degree of satisfaction!
We can analyse the demand for beer and see how it varies with changes in price and income. Minimum prices for alcohol have been proposed as a means of reducing consumption, and tax and excise duties are always linked to alcoholic beverages and clearly have an effect on demand. In this case, however, we can also consider the emergence of Asia and how tastes have changed. It is the fastest growing beer market in the world; so what can we deduce from that? As the BBC News article states, it is ‘a sign of a young, upwardly mobile, and increasingly hedonistic population.’
Experts also say that the increased consumption of beer in Asian countries is closely correlated with growing incomes and prosperity. A consumer research analyst from Standard Chartered, Nirgunan Tiruchelvam, said:
“Beer has a clearer correlation with strong economic growth … People tend to drink beer in times of growth. They drink spirits when times are good and when times are bad.”
Data suggest that when a certain level of prosperity is reached in a nation, beer sales begin to rise. As many Asian economies begin to develop rapidly, beer sales have taken off. This could be regarded as a good thing for Europe. With stagnant Western economies, beer producers within Europe may be grateful for a growing demand in Asia. Indeed, many of the world’s biggest breweries are expanding rapidly, providing jobs and income. Consumers in Europe will also be happy to see that beer production remains profitable in other parts of the world. With unemployment still high and recession ongoing, a pint of beer will be a much needed pick-me-up for many people. At least, that’s what the evidence from the Great Depression of the 1930s suggested!!
It’s not good news for everyone, however. Beer production has also increased in Asian countries, most notably in China, which now leads the world as the largest beer producer. This clearly reduces the export potential for European beer producers.
Also, many argue that the growing consumption of beer in Asia is simply an illustration of growing Western influence and it is likely to create severe medical problems in the future. Binge drinking and under-age consumption is already a big problem in Western countries and this could soon begin to extend across the world. The following articles consider the growth in consumption of beer.

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.

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.
