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.

Questions
- How would you define a luxury good? What is the relationship with income?
- How could an increase in car sales benefit the economy? How could the multiplier effect have an impact?
- Which factors have contributed towards the growth in low-emissions cars?
- Sales of low-emissions cars have significantly increased. However, why is this increase
- What are some of the key things that can help to bring a recession to an end? Into which general category would you place this increase in car sales?
- Fuel duty is expected to rise later this year. How might this affect the number of new car registrations? What does your answer tell you about the cross elasticity of demand?
A bumper olive crop in Spain would seem to be good news for Spanish olive growers. But the effect has been a fall in the prices of olives and olive oil. With 43% of the global supply, Spain is the world’s largest olive oil producer and changes in Spanish output have a big effect on the world price.
Premium extra virgin olive oil has fallen to its lowest level (even in nominal terms) since 2002. Today the price is around $2900 (£1850) a tonne in the wholesale market; in May 2006 it peaked at nearly $5854 – double today’s price.
And while this is bad news for Spanish farmers, for farmers in countries without bumper harvests, the low prices are even harder to bear.
The problem is being exacerbated by a fall in demand in many countries currently suffering recession, such as Greece, Portugal and Italy – all big olive oil consumers. Although olive oil prices have fallen, it is still more expensive than various substitutes. Many people are thus buying these cheaper alternatives, such as sunflower oil, especially for cooking.
What is more, cheaper substitutes for olive oil are increasing in supply. Take the case of rape seed oil in the UK. As the Mail Online article, linked to below, reports:
“UK rape planting is thought to have hit an all-time high this year as British farmers take advantage of the high prices being demanded for rapeseed – base ingredient of many vegetable oils and other edible oils.
Much of the UK crop is used by the local food industry, although some analysts are predicting strong UK yields will give farmers the opportunity to export more to Europe. Because of rising export demand, oil users in the UK claim there is little to indicate the price they are paying for rapeseed oil will drop substantially in the near future.”
The market for olive oil is global. Crop yields in one part of the world, both of olives and of substitute crops, affect global prices and hence growers’ incomes worldwide.

Calls for a simplified tax and benefit system have been ongoing and many see the Coalition’s plans for a Universal Credit as a step in the right direction. However, a second suggestion set out in a report by lobbying groups is to introduce a single rate of income tax at 30%. The argument is that it will simplify the system, help lower income earners and boost growth.
As well as the introduction of a single rate of income tax, The 2020 Tax Commission’s Report also suggests an increase in the personal allowance to £10,000; scrapping National Insurance Contributions, stamp duty, inheritance tax and air passenger duty, as well as cutting fuel duty by 5p. For the typical tax payer, it may sound great – the difference between your gross and your net pay would narrow, but the wider consequences must be considered. Although a single rate of income tax would undoubtedly simplify the system, the impact on government finances must be considered. The commission predicts that overall borrowing would fall by £35bn after 15 years, but that the national deficit would increase by £49.1bn in the first year. Perhaps not an ideal solution given the current state of the national deficit!
The report does contain some radical change, but the idea of simplification is well-recognised as a necessary principle of any tax system. As the Chairman of the Commission, Allister Heath said:
It is time for Britain to make a vital choice between tweaking the status quo and letting our economy continue to be crippled by complex and punitive taxes, and drastically changing course with a radical but realistic plan for a tax system fit for the 21st century.
The 2020 Tax Commission has set out that plan and would ensure that income is taxed once at a single, much more reasonable rate. It could create the conditions to establish the UK as a global trading hub, generating renewed prosperity for all those who live and work here.
The current system is complex and many people end up paying an extremely high rate of tax, once everything has been paid. The Guardian article below gives a nice illustration. “If you earn income from shares, first corporation tax is taken out of the profits. Then you pay taxes on the dividends. Then because those profits drive up the share price you pay capital gains tax as well.” With a simpler and fairer tax system, the Commission argues that it will boost the competitiveness of the UK economy and help boost its struggling growth rate. How many, if any, of these proposals will be incorporated into the government’s plans is anybody’s guess, but it definitely presents an interesting solution and problem.
