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 the financial crisis came accusations towards the banking sector that they had taken on too many bad risks. Banks were lending money on more and more risky ventures and this in part led to the credit crunch. Since then, bank lending has fallen and banks have been less and less willing to take on risky investments.
Small businesses tend to fall (rightly or wrongly) into the category of high risk and it is this sector in particular that is finding itself struggling to make much needed investments. All businesses require loans for investments and improvements and if the banking sector is unable or unwilling to lend then these improvements cannot take place.
Quantitative easing has been a key response across the world to the credit crisis to encourage banks to begin lending to each other and to customers. A new government backed scheme worth £20bn aims to increase bank lending to small and medium sized enterprises (SMEs). By guaranteeing £20bn of the participating banks’ own borrowing, lenders will be able to borrow more cheaply than normal. As the banks (so far including Barclays, Santander, RBS and Lloyds Banking Group) can borrow at a cheaper rate, they will therefore be able to pass this on to the businesses they lend to. Under this National Loan Guarantee Scheme (NLGS), businesses will be able to borrow at interests rates that are 1 percentage point lower than those outside the scheme. £5bn will initially be made available with subsequent installments each of £5bn to come later.
With the Budget looming, the Chancellor is keen to show that the government is delivering on its promise to give smaller businesses access to finance at lower interest rates. If this initiative does indeed stimulate higher lending, it may be a much needed boost for the economy’s faltering economic growth. Criticisms have been leveled at the scheme, saying that although it is a step in the right direction, it can by no means be assumed that it will be sufficient to solve all the problems. In particular, the NLGS is unlikely to provide much help for those small businesses that can’t get finance in the first place, irrespective of the cost of the borrowing. Furthermore some banks, notably HSBC, have chosen not to participate in the scheme, due to it not being commercially viable. The overall effect of this scheme will take some time be seen, but if it is effective, it could give the economy and the small business sector a much needed boost.

Original post (19/9/11)
The Independent Commission on Banking (ICB), led by Sir John Vickers, has just delivered its report. Central to its remit was to investigate ways of making retail banking safer and avoid another bailout by the government, as was necessary in 2007/8.
The report recommended the ‘ringfencing’ of retail banking from the more risky investment banking, often dubbed ‘casino banking’. In other words, if the investment arm of a universal bank made a loss, or even faced collapse, this would not affect the retail arm. The ringfenced operations would include banking services to households and small businesses. Wholesale and investment banking would be outside the ringfence. As far as retail banking services to big business are concerned, these could be inside the ringfence, but details would need to be worked out about precisely which banking services to big business would be inside and which would be outside the ringfence.
The ICB was keen to stress that the ringfence should be high and that the retail arm should be both operationally and legally separate from the wholesale/investment arm. The ringfenced part of the bank should have a capital adequacy ratio of up to 20% (above the Basel III recommendations), with at least 10% of liabilities in the form of equity. Capital could only be moved from the ringfenced arm to the investment arm of the bank if this did not breach the 10% ratio.
The ICB report also recommends measures to increase competition in banking, including making it easier to switch accounts, greater transparency about the terms of accounts and a referral of the banking industry for a competition investigation in 2015. The cost to the banking industry of the measures, if fully implemented, is estimated to be between £4m and £7m.
Because of the requirement in the report for banks to build up their capital and the danger that a too rapid process here would jeopardise the expansion of lending necessary to underpin the recovery, banks would be given until 2019 to complete the recommendations. Moves towards this, however, would need to start soon.
Update (19/12/11)
In December 2011, the government announced that it would accept most of the ICB report, including separating retail and investment banking. It would not, however, demand such stringent capital requirements as those recommended in the report.
The following articles examine the details of the proposals and their likely effectiveness. The later articles examine the government’s response.

Questions
- Explain the difference between a capital adequacy ratio and a liquidity ratio. Will the Vickers proposals help to increase the liquidity of the retail banking arm of universal banks?
- Does it matter if equity capital in excess of the 10% requirement for retail banking is transferred to a bank’s investment arm?
- What risks are there for a bank in retail banking?
- What are the advantages and disadvantages of bringing in the measures gradually over an 8-year period?
- Does it matter that the capital adequacy requirements are higher than under the internationally accepted standards in Basel III?
- Assume that there is another global financial crisis. Will the proposals in the report mean that the UK taxpayer will not have to provide a bailout?
Most people are risk-averse: we like certainty and are generally prepared to pay a premium for it. The reason is that certainty gives us positive marginal utility and so as long as the price of insurance (which gives us certainty) is less than the price we place on certainty, we will be willing to pay a positive premium. By having insurance, we know that should the unexpected happen, someone else will cover the risk. As long as there are some risk-averse people, there will always be a demand for insurance.
However, will private companies will be willing to supply it? For private market insurance to be efficient, 5 conditions must hold:
1. Probabilities must be independent
2. Probabilities must be less than one
3. Probabilities must be known or estimable
4. There must be no adverse selection
5. There must be no moral hazard
If these conditions hold or if there are simple solutions, then insurance companies will be willing and able to provide insurance at a price consumers are willing to pay.
There are many markets where we take out insurance – some of them where insurance is compulsory, including home and car insurance. However, one type of insurance that is not compulsory is that for cyclists. No insurance is needed to cycle on the road, but with cycle use increasing and with that the number of accidents involving cyclists also increasing, the calls for cyclists to have some type of insurance is growing. If they are hit by someone without insurance and perhaps suffer from a loss of income; or if they cause vehicle damage, they will receive no compensation. However, whilst the risk of accident is increasing for cyclists, they are still statistically less likely to cause an accident than motorists. Perhaps a mere £30 or £40 per year for a policy is a price worth paying to give cyclists certainty. At least, this is what the Association of British Insurers (ABI) is claiming – hardly surprising when their members made a combined loss of £1.2 billion!

Questions
- With each of the above conditions required for private insurance to be possible, explain why each must hold.
- What do we mean by no moral hazard and no adverse selection? Why would their existence prevent a private company from providing insurance?
- Using the concept of marginal utility theory, explain why there is a positive demand insurance.
- What might explain why cyclists are less likely to take out insurance given your answer to the above question?
- Do you think cyclist insurance should be compulsory? If governments are trying to encourage more sustainable transport policy, do you think this is a viable policy?
Cycling generated £2.9 billion for the UK economy in 2010 – a rise of 28% over 2009. This amounts to an average ‘Gross Cycling Product’ of £233 for each of Britain’s 12½ million cyclists. What is more, the figures are likely to continue growing rapidly in future years. This is the central finding of the LSE report, The British Cycling Economy, authored by Dr Alexander Grous, a productivity and innovation specialist at the Centre of Economic Performance (CEP) at the London School of Economics.
The major benefits to the economy from cycling include the sale of cycles and accessories, cycle maintenance, the generation of wages and tax revenues from 23,000 people employed directly in bicycle manufacture, sales, distribution and the maintenance of cycling infrastructure. There are also health benefits. These are partly the direct benefits to the economy of fewer days taken in sick leave by cyclists (a contribution of £128 million in 2010) and partly the health and well-being benefits to the individual and the saving on healthcare expenditure.
But are enough people being encouraged to get on their bikes? What are the major incentives for people to cycle? The report identifies the following:
• Cycling being made both segment- and gender-neutral, appealing to the widest number of user groups, across all ages and genders;
• Coordinated and preferential traffic signals that facilitate faster and safer journeys;
• ‘Short cut’ routes in dense urban areas and capital cities that join arterial road routes;
• Traffic calming initiatives that include road narrowing and speed restrictions that range from 30km/h to ‘walking speeds’;
• Extensive parking and in some areas, designated women-only spaces with CCTV and enhanced lighting;
• Established bike rental schemes;
• Long-running training programmes for children;
• The prevalence of strict ‘liability laws’ that assume a car driver is responsible in the event of a collision between a car and a cyclist.
Read the following articles and report and then consider, as an economist, how the benefits and costs should be analysed and what policy implications might follow.
