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.

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

  1. What are the key principles of a good tax system?
  2. Explain how taxation affects the incentive to work?
  3. What is the difference between tax evasion and tax avoidance?
  4. 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.
  5. Why is tax avoidance of such concern at the moment? Think about the current state of the economy.
  6. What are taxes and national insurance contributions used to pay for?
  7. To what extent do you think tax avoidance is a natural consequence of any tax system?

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.

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.
