When crude oil prices go up, the prices of petrol and diesel go up pretty well straight away and by the full amount, or more, of the crude price rise. When crude prices go down, however, road fuel prices are often slow to fall; and when they do, the fall is less than the full fall in crude prices.

In response to complaints of motorists and haulage companies, the Office of Fair Trading has announced that it will investigate the link between crude prices and prices at the pump. It will report in January 2013.


The review will consider questions of competition and market power. In particular, it will look at the power of the oil companies in determining the wholesale price of road fuel.
It will also examine the retail fuel sector and whether supermarkets are driving out independent retailers. The claim of many independent petrol stations is that supermarkets are selling below cost as a lost leader to encourage people to shop in their stores. They also claim that supermarkets use their buying power to obtain fuel more cheaply.
What is more, most of the petrol stations that are not part of supermarkets are owned by the oil companies. Again, independents claim that oil companies supply fuel more cheaply to their own stations than to independents.
As a result of what many independents see as unfair competition, many are driven out of business. Today there some 9000 petrol stations in the UK; 20 years ago there were twice as many.
The following articles look at the remit of the OFT investigation and at the competition issues in the road fuel market.

Let’s face it – no-one likes paying tax! After all, to see your monthly pay decline by £1000 through taxation and national insurance has got to hurt. Yet, taxation and national insurance contributions are essential sources of government revenue to finance benefits and public and merit goods.
However, with so much attention given to the UK’s ‘culture of dependency’, many people are increasingly angry with having to pay so much in taxation to see it being spent by the government on individuals who in some cases choose not to work and at the same time seeing other rich people paying so little in taxation. The increase in the top rate of tax received a lot of coverage. Although it did make the tax system more progressive, there were many concerns that it would lead to lower growth, a lack of innovation and enterprise and increased tax evasion and avoidance, as the super-rich were being hit with phenomenal tax bills. The post on the 50p income tax available here is worth looking at again to think about the effect that taxes have on incentives.
The issue of tax avoidance is by no means new, but with a large budget deficit in the UK, tax avoidance by the super-rich has become something that everyone has an opinion on. The average household has seen its income squeezed more and more, as the government continues its efforts to cut the deficit. The fact that the super rich are avoiding sometimes millions in taxation, while the average household struggles to pay even the basic rate of tax, creates a rather contentious issue. The Chief Secretary to the Treasury, Danny Alexander, has said that the basic rate of tax could be cut by 2p in the pound if tax avoidance came to an end. He commented to the BBC’s Sunday Politics Programme that:
‘We have to make sure that everybody, especially the rich and famous, are paying their fair share of tax…These sorts of schemes that save wealthy people potentially tens of millions of pounds in tax, they are paid for by everybody else… If we could narrow the tax gap in this country by a quarter we could reduce income tax for every basic rate payer by 2p in the pound.’
This would clearly have some very positive effects on some of the poorest people living in the UK.
There is a variety of tax avoidance schemes available and the one receiving the most attention at present is the Jersey-based K2 scheme, which Jimmy Carr and others are thought to be using. The Public Accounts Committee will be reporting on the problem of using private companies to pay salaries, as a means of avoiding income tax and national insurance contributions.
If tax avoidance could be stopped, or at least reduced, then not only could basic rate tax payers benefit, but it might go some way to cutting the budget deficit, giving the government more flexibility in stimulating the economy. According to HMRC, tax avoidance and evasion cost the economy some £42 billion – enough to pay off one-third of Britain’s budget deficit.
The following articles consider the problem of tax avoidance and then try answering the questions on the issue of taxation.

Questions
- What are the key principles of a good tax system?
- Explain how taxation affects the incentive to work?
- What is the difference between tax evasion and tax avoidance?
- Using indifference analysis, illustrate the effect of a cut in the basic rate of income tax. How does it affect the decision to work more or less? You should consider the income and substitution effects in your answer and which rate of tax (if any) an individual is paying.
- Why is tax avoidance of such concern at the moment? Think about the current state of the economy.
- What are taxes and national insurance contributions used to pay for?
- To what extent do you think tax avoidance is a natural consequence of any tax system?
Youth unemployment has been one of the main headlines for some months, with data showing a record number of young people out of work.
As part of the government’s £1bn Youth Contract that aims to help young people back into work and help those unable to find employment, Nick Clegg has announced wage subsidies to firms hiring 18-24 year olds will be paid earlier.
Some of the costs of unemployment are obvious. For the individual who is unemployed, it means a lack of income and hence inability to buy goods and services. This then has wider implications for the economy. If people are unable to purchase goods and services, this contributes to a lower level of aggregate demand, which in times of recession, is hardly ideal.
Unemployment also means an inefficient use of resources, meaning the economy is operating below full capacity. Fewer people in work also implies lower tax revenues for the government, at the same time as higher unemployment benefit payments, contributing towards a growing budget deficit. This point is of particular concern, when it is young workers claiming benefits, as it could mean a life of dependency.
There are also some longer-term consequences, in particular for those who have been out of work for some time. They lose their skills, making it harder to find a job and this can pose costs to employers and further costs to the government through re-training. As such, government initiatives to tackle youth unemployment have never been more important.
The wage subsidies that were announced back in November will now be paid when young people have been out of work for six months, instead of nine. This initiative aims to help reduce youth unemployment in areas where it is at its worst. Twenty local authorities have been identified as priorities for the government and will benefit from this scheme. As Nick Clegg said to CBI summit:
“Three months can make all the difference. When you feel like your banging your head against a brick wall, when you live in an area where opportunities are already few and far between, another 12 weeks of rejection letters, of being cut off, of sitting at home waiting, worrying, that can seriously knock the stuffing out of you, making it extremely difficult to pick yourself up …
So jobcentres will be able to make use of the subsidy before people are referred to the Work Programme, capitalising on their links with local employers, and they’ll also intensify support, so more training, more regular coaching, spending more time with young people to knock a CV into shape or prep ahead of an interview.”
There are critics of the scheme, who argue that it is too little, too late and that it will simply displace older workers, thereby creating worse unemployment for another group. Until the economy begins to grow and confidence returns to the markets, unemployment is likely to remain a frequent headline. The following articles consider the wage subsidy and the state of unemployment in the UK.

The pensions crisis is one area of social policy that has been the focus of attention for some years. With an ageing population, more people entering higher education and a rather substantial deficit facing the government, pension reform has been high on the agenda and not just in the UK.
A number of factors have contributed towards the so-called pensions crisis: rising life expectancy; the ‘baby-boomers’ retiring; more people staying in education for longer; an ageing population. All of these have led to a dependency ratio that is becoming worse – fewer workers to support every pensioner. Over the past few years, strikes have taken place in protest to government pension plans, especially for public sector workers, who see the proposals as making them worse off once they retire. Doctors are the latest group to strike in protest over having to work longer before retiring and having to pay higher national insurance contributions.
So, are the doctors justified in their protests? They are currently on a final-salary pension scheme, which is a very generous scheme, although it is being phased out and replaced with a career average scheme, which will have big implications for doctors’ pensions. Furthermore, there was an overhaul of their pensions in 2008, thus the criticism that further changes are now being made to make them even worse off. Doctors do pay higher national insurance contributions than other occupations, such as teachers and they will naturally receive a higher pension than other NHS workers, such as nurses simply because they earn more. However, this does have big implications for their future.
Inequality is a big issue across the UK and this doesn’t only refer to income. Those earning higher salaries are more likely to live longer than the average worker. So, we see life expectancy inequality as well. The consequence of this is that once an individual retires at say 60, if your life expectancy is 85, then you have 25 years to live in retirement receiving whatever pension you have accumulated throughout your working life. If, however, your life expectancy is only 75, perhaps because of your background, your occupation, your health, then you will only spend 15 years in retirement. The person that lives longer therefore receives significantly more in pension payments and if this differing life expectancy is related to your occupation and thus your salary, then inequality of income clearly has some very wide implications for pension schemes and rates of contribution.
There are, of course, wider effects of any industrial action by doctors. Whilst some may agree with their view that this further pension reform is unfair, if any strike action does take place there will be wider economic effects. Those in need of treatment may have to delay it and if that means more people taking sick days, then the economic cost to the economy could be significant. The following articles consider the latest controversy in public-sector pensions.

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.
