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.

The technology sector is highly complex and is led by Apple. However, as the tablet market is continuing to grow, it is becoming increasingly competitive with other firms such as Samsung gaining market share. Although both firms sell many products, it is the growing tablet market which is one of the keys to their continued growth.

Tablet PCs have seen a growth in the final quarter of 2012 to a high of 52.5 million units, according to IDC. Although Apple, leading the market, has seen a growth in its sales, its market share has declined to 43.6%. Over the same period, Samsung has increased its market share from 7.3% to 15.1%. While it is still a huge margin behind Apple in the tablet PC market, Samsung’s increase in sales from 2.2 million to 7.9 million is impressive and if such a trend were to continue, it would certainly cause Apple to take note.

It’s not just these two firms trying to take advantage of this growing industry. Microsoft has recently launched a new tablet PC and although its reception was less than spectacular, it is expected that Microsoft will become a key competitor in the long run. There are many factors driving the growth in this market and the war over market share is surely only just beginning. The chart shows the 75.3% growth in sales in just one year. (Click here for a PowerPoint of the chart.)

A Research Director at IDC said:

We expected a very strong fourth quarter, and the market didn’t disappoint…New product launches from the category’s top vendors, as well as new entrant Microsoft, led to a surge in consumer interest and very robust shipments totals during the holiday season’

Apple has been so dominant in this sector that other companies until recently have had little success in gaining market share. However, with companies such as Samsung and ASUS now making in-roads, competition is likely to become fierce. There are already concerns that Apple’s best days are behind it and its share price reflects this. People are now less willing to pay a premium price for an Apple product, as the innovations of its competitors have now caught up with those of the leading brand name. The following articles consider this growing market.

  6. Microsoft’s new tablet didn’t attract huge sales. What explanation was given for this? Use a diagram to help answer this question.
  7. Tablet PCs are relatively expensive, yet sales of them have increased significantly over the past few years. What explanation is there for this, given that we have been (and still are) in tough financial times?

The housing market is an incredibly fascinating market to monitor and to research. The market was at the centre of the financial crisis with some lenders accused of over-aggressively expanding their mortgage books and relaxing their lending criteria. The UK housing market of today looks very different to the market before the financial crisis. Nationally, house prices are stagnant while transaction numbers are less than half their pre-crisis level. The UK housing market appears almost as ‘cold’ as the recent weather!

As the first chart shows, the annual rate of house price inflation across the UK has been consistently close to or even below zero over the past couple of years. The latest figures from the Nationwide Building Society point to the average UK house price in the final quarter of 2012 being 1.1 per cent lower than in the final quarter of 2011. The figures from the Halifax concur with their estimate showing UK house prices 0.3 per cent lower year-on-year in the final quarter of 2012. This is a very different picture from that during the 2000s. As recently as 2007, the annual rate of house price inflation was in excess of 10 per cent.

Another indicator of the changing face of the UK housing market is the level of activity. The second chart shows the number of transactions per quarter across England and Wales since 1996. The figures from the Department of Communities and Local Government show that since the start of 2010 England and Wales has seen an average of 159,000 transactions per quarter. This compares with an average of 294,000 transactions over the period from 1996 to the end of 2007. Hence, the number of purchases today is roughly half the level prior to the financial crisis.

A further indicator of today’s very different housing market is the numbers of approvals by lenders for mortgages for house purchases. The latest Bank of England figures show that across the UK, the number of approvals each month in the first eleven months of 2012 averaged 51,000. Since 2010, the average monthly number of approvals has been 49,000. However, over the period from 1996 to the end of 2007 there were over 102,000 mortgages being approved each month.

A trawl through some of the key indicators of the UK housing market helps to paint a picture of a market that is markedly different to that before the financial crisis. It would be a big surprise in today’s financial and economic climate if there were to be any significant change in the path of these indicators for some time.

  2. Using a demand-supply diagram, illustrate the forces that have affected house prices in the late 2000s and early 2010s.
  3. Draw up a list of issues surrounding the housing market that would be of interest to a microeconomist. Now repeat the exercise for a macroeconomist.
  4. Why are house prices so notoriously volatile? Can you think of any other markets where prices are similarly volatile? Do these markets share any common traits?
  5. If you were a commentator on the UK housing market what would you be forecasting for prices and activity in 2013?

It’s a relatively common dish to see on a menu at a restaurant: mackerel. This particular fish has been promoted as a healthy and sustainable dish, but now its sustainability is coming into question and the Marine Conservation Society has taken it off its ‘fish to eat’ list. My brother Hugh is a marine biologist and often comments on which fish we should be avoiding due to sustainability issues (especially given how much I like fish!) So, how is this an economics issue?

There a couple of key things to pick out here. Firstly, with the conservationists’ warning of this issue of unsustainability, they have been asking consumers to reduce the amount of mackerel they buy. This will naturally have an impact on fisherman. If consumers do listen to the conservationists and hence reduce their demand for mackerel, we could see a fall in the price of this fish and a reduction in the fishermen’s turnover. It could be that we see a switch in consumption to other more sustainable fish, especially if we see some form of intervention.

Another area concerning economics is the idea of over-fishing. For years, there have been disputes over who has the rights to these fish stocks. In the past, the Faroe Isles and Iceland have increased their quotas significantly, as mackerel appear to have migrated to their shores, contributing to this question of sustainability. Iceland and the Faroe Isles have ‘unilaterally agreed their quotas … as they are not governed by the common fisheries policy’.

The question is: when fisherman catch one additional mackerel, what are they considering? Do they think about the private benefit to them (or their company) or do they consider the external cost imposed on others? Whenever one fish is taken from the sea, there is one less fish available for other fishermen.

This leads to over-consumption of fish and contributes towards the well-documented depletion of fish stocks and ‘The Tragedy of the Commons’, if account is not taken of the external cost imposed on other fishermen.

The total catch is now far in excess of what has been scientifically recommended and previously agreed upon by all participating countries. Negotiations to introduce new catch allowances have so far failed to reach agreement.

There are hopes that an international policy on quotas can be agreed to ensure mackerel levels return to or remain at a sustainable level. However, at present no progress has been made. Until some form of an agreement is reached, fishermen around Iceland and the Faroe Isles will continue to battle against the conservationists. The following articles consider this fishy topic.

  3. What is the Tragedy of the Commons? Using a diagram with average and marginal revenue product and average and marginal cost illustrate the market equilibrium and the social optimum. Why are they different?
  4. Following on from question 3, what does this suggest about the role of governments?
  5. If the conservationists’ request regarding buying less mackerel is successful, what impact might this have on fishermen and fisheries?
  6. If consumers do switch to buying other fish, what would happen to the equilibrium in the mackerel market and in the market for other fish? Think about this question in terms of general equilibrium analysis.
