From early January to late February 2013, the average pump price of petrol in the UK rose by over 6p per litre – a rise of 4.7% in just seven weeks. There have also been substantial rises in the price of diesel.

The higher prices reflect a rise in the dollar wholesale price of oil and a depreciation in the pound. From 2 January to 21 February the pound fell from $1.63 to $1.53 – a depreciation of 6.1% (see). Crude oil prices (in dollars) rose by just under 7% over this period. With oil imports priced in dollars, a weaker pound pushes up the price of oil in the UK. The price has then been pushed up even higher by speculation, fuelled by the belief that prices have further to rise.

The higher price of road fuel, plus the general squeeze on living standards from the recession, with prices rising faster than wages, has caused a reduction in the consumption of road fuel. Petrol sales have fallen to their lowest level for 23 years. Sales in January 2013 were 99m litres down on the previous month’s sales of 1564m litres (a fall of 6.3%).

Not surprisingly motorists’ groups have called for a reduction in fuel taxes to ease the burden on motorists. They also argue that this will help to drive recovery in the economy by leaving people with more money in their pockets.

Equally not surprisingly, those concerned about the environment have welcomed the reduction in traffic, as have some motorists who like the quieter roads, allowing journey times to be cut, with resulting reductions in fuel consumption per mile.

The following videos and articles discuss the causes of the most recent fuel price rises and also examine the responsiveness of demand to these higher prices and to the reductions in real incomes.

Investment is crucial in all sectors of the economy. With growing demand for travel abroad, airports across the world have begun implementing investment strategies to increase capacity. Airport bosses at Heathrow are currently considering a 5 year investment plan that is expected to cost £3 billion.

Although investment is certainly needed and passengers will benefit in the long run, the cost of this investment will have to be met by someone. If these plans are approved by the airport bosses, it is likely that ticket prices will be pushed upwards to pay for it. Any increase in charges will have to receive approval by the Civil Aviation Authority (CAA). The plan at the moment would see ticket prices, via landing charges, increase by £19.33 per passenger before a further rise to £27.30. The impact on customers has already been raised as a key concern.

If the investment plans proceed, Heathrow expects to see its passenger numbers increase by 2.6m over the next 5 years, despite the proposed price hikes. This would naturally increase revenue and this money would provide at least some of the funds to repay the cost of the investment.

The price rises have been described as ‘incredibly steep’ and there are concerns that they will penalize customers. Airlines, such as Virgin Atlantic have recognized the need for more investment, but are more focused on finding ways to provide it without the price rises.

However, Colin Matthews, the Heathrow Chief said:

Heathrow faces stiff competition from other European hubs and we must continue to improve the service we offer passengers and airlines.

Passengers have already seen prices rise and Heathrow’s cost base has been described by British Airways as ‘inefficient’. Despite the fact that the decision by the CAA is not expected until January 2014, speculation will undoubtedly continue until any decision is reach. The following articles consider this case.

Six of the major tea producing countries – India, Kenya, Sri Lanka, Indonesia, Rwanda and Malawi – have formed an International Tea Producers’ Forum (ITPF). Together these countries produce slightly more than the world’s tea. The hope of the members of the new ITPF is that their cartel will allow them to increase the price of tea to the growers and to create greater price stability.

According to the Assam Tribune article below:

ITPF’s main objectives include – safeguarding the interests of the tea-producing countries, evolving collective solutions for the problems facing the producers, providing technical cooperation, sharing of technology and expertise by the member countries, undertaking market studies and research projects to address any specific issues concerning tea in general or any variety of tea, among others.

And according to the article from Sri Lanka’s Daily News:

Chairman of the Planters’ Association of Ceylon, which represents the interests of 23 Regional Plantation Companies, Lalith Obeyesekere said this was a landmark occasion. Sri Lanka particularly looks to the forum to provide long-term sustainability to the tea industry in maintaining price stability and quality standards, among the other objectives set out in the mandate… The Planters’ Association said they were confident that Sri Lanka could use the ITPF to re-look at the industry in order that local tea producers realize their full potential.

Sri Lanka’s plantation industries minister Mahinda Samarasinghe said:

The bulk of production is in the hands of smallholders. So there’s a need to increase their incomes. Price stability is definitely important.

The main aim of the ITPF over the longer term is likely to be to raise tea prices. The chart shows international tea prices from 1983 to the present day. As you can see, they have fluctuated considerably. Note that these are prices in nominal terms and hence do not take inflation into account. Click here for a PowerPoint of the chart.

But if the main aim is to increase prices to tea growers, how could this be achieved? One objective of the ITPF is to stimulate demand for tea by ‘promoting tea consumption through generic promotional campaigns’. The aim would be to encourage people to switch from coffee and soft drinks.

But to take advantage of its market power, the cartel might also want to reduce tea production, thereby pushing up the price. This, of course, would be more feasible if it had a larger than 50% share of the market.

Although production quotas are not currently part of the agreement, these are likely to be considered at future meetings, especially if the three other large producers – China, Vietnam and Iran – can be persuaded to join.

China, with some 38% of the market, is the world’s largest tea producer. Although it sent an observer to the meeting (as did Iran), it was not one of the signatories. If it could be persuaded to join the cartel, this would increase its power. Nevertheless, China specialises in different types of tea, mainly green teas, and is not the world’s biggest exporter – that is Kenya.

Ministers are considering introducing a minimum price of 45p per unit of alcohol on all drinks sold in England and Wales. The Scottish government has already passed legislation for a minimum price of 50p per unit in Scotland. This, however, is being challenged in the Scottish courts and is being examined by the European Commission.

As we saw in a previous blog, Alcohol minimum price, the aim is to prevent the sale of really cheap drinks in supermarkets and other outlets. Sometimes supermarkets sell alcoholic drinks at less than average cost as a ‘loss leader’ in order to encourage people to shop there. Two-litre bottles of strong cider can be sold for as little as £2. Sometimes they offer multibuys which are heavily discounted. The idea of minimum pricing is to stop these practices without affecting ‘normal’ prices.

The effect of a 45p minimum price per unit would give the following typical minimum prices (depending on strength):

Strength Size Minimum price
Wine 12.5% 750ml £4.22
Beer/lager (normal) 4.5% pint (568ml) £1.15
Beer/lager (strong) 7.5% pint (568ml) £1.92
Beer/lager (normal) 4.5% 2 litres £4.05
Beer/lager (strong) 7.5% 2 litres £6.75
Cider (normal) 5% pint (568ml) £1.28
Cider (strong) 8% pint (568ml) £2.04
Cider (normal) 5% 2 litres £4.50
Cider (strong) 8% 2 litres £7.20
Whisky 40% 700ml £12.60
Vodka 37.5% 700ml £11.81

The hope is that by preventing the sale of really cheap drinks in supermarkets, people will no longer be encouraged to ‘pre-load’ so that when they go out for the evening they are already drunk.

But how successful will such a policy be in cutting down drunkenness and the associated anti-social behaviour in many towns and cities, especially on Friday and Saturday nights? The following articles discuss the issue and look at some of the evidence on price elasticity of demand.

Increases in the cost of living over the past few years have put many families under financial pressure. One of the main factors that has been hurting households is the price of petrol and diesel. Road fuel duty was due to be increased last August, but the Chancellor delayed it in June. However, a planned 3p rise in duty by the Coalition, which has faced rebellion from numerous MPs may now be delayed further, following a hint from the Treasury.

The government has said that it will do everything it can to support struggling families with the cost of living and this has led many to conclude that in the Autumn Statement, the Chancellor will delay the planned 3p rise. Labour was defeated in its efforts to force a delay of the proposed 3p duty rise, as Tory bankbenchers were given this hint that the Treasury would decide to delay the increase anyway. The Economic Secretary to the Treasury said that fuel duty is part of the government’s strategy to help cut the cost of living. He commented that fuel duty was 20% lower in real terms compared to March 2000, when it was at its peak.

If we had continued with the policies of the previous government, quite simply prices would be higher, fuel would be 10p more expensive per litre. I know some will call for a further freeze in fuel duty today. I can assure them this government understands the financial pressures hard-working families are facing. Subject to the constraints of the public finances, this government is determined to help families with the cost of living.

A key economic question to consider is why is fuel one of the products that is frequently taxed? When a tax is imposed on a product, its price will rise and as the law of demand tells us, this will cause people to purchase less of it. But, what is so special about petrol? Why do people continue to purchase petrol even when its price rises? The following articles consider the concerns surrounding the 3p fuel duty rise.
