Demand and supply analysis can be applied to a multitude of markets. When there is a disequilibrium in a market, prices will tend to adjust to eliminate any shortage or surplus. But, what of road space? There is a demand and a supply of road space and when there are too many cars for the road space available, congestion is the consequence.
When an additional car enters the road network, there is a cost and a benefit to the driver. However, there are not only costs/benefits to the driver, but there are also costs/benefits to other road-users. When one car drives on the M25 it adds to the number of cars on the road. Once we reach the point where there are too many cars given the road space and thus the flow of cars per minute begins to fall, congestion starts to build up. There is a negative externality involved here – the actions of one person (the driver) impose an additional cost on other drivers (the congestion). It takes every other road user a little bit of extra time to get from A to B the more cars there are on the road.
Congestion is a problem in many parts of the country and various solutions have been suggested. Policies to reduce demand will help the congestion problem by reducing the number of cars on the road. Numerous strategies have been tried, such as restrictions on parking; improvements in public transport; an integrated transport policy; higher parking charges; work place parking levies; higher taxes on petrol, higher car taxes and congestion charging schemes.
Alternatively, building more roads will directly increase the supply of road space, but this can (and has) simply led to more cars using the additional road space and thus the problem of congestion remains. Bus/taxi lanes are in use across the country and allow the users of public transport to benefit from faster journey times, thus encouraging them to forgo their cars and use buses. However, does this add to the congestion for other people?
In Liverpool, a nine month trial is taking place, where bus lanes will be removed to find out if they have a positive effect on reducing congestion. By increasing the amount of road space available to all road users, Liverpool City Council will be able to see if directly increasing the supply of road space will help to meet the existing demand. The possibility, however, is that by increasing the supply of road space, more individuals will choose to use their cars, thus fuelling demand. Many argue that this trial is a step backwards and will add to congestion, reduce the appeal of travelling by bus and impose further costs on the environment. The following articles consider the debate surrounding congestion.

Questions
- Explain why congestion is a negative externality. What other externalities exist with regard to car usage?
- Using a diagram, show the point at which congestion occurs and explain why there is a difference between the marginal private and marginal social cost.
- What will happen to the difference between the marginal private and social cost curves before and after congestion sets in?
- Think about the different solutions to the problem of congestion. In each case, explain whether it is a demand-side or supply-side solution and how it will aim to combat congestion. You should also consider whether it is a short or long term solution and how feasible it actually is.
- How will the abolition of bus lanes aim to reduce congestion?
- There are supporters for bus lanes and supporters for the abolition of them. Justify the arguments on each side of the debate. You should consider the wider implications as well as the impact on congestion.
The cost of living is a contentious issue and is likely to form a key part of the political debate for the next few years. This debate has been fuelled by the latest announcement by SSE of an average rise in consumer energy bills of 8.2%, meaning that an average dual-fuel customer would see its bill rise by £106. With this increase, the expectation is that the other big energy companies will follow suit with their own price rises.
Energy prices are made up of numerous factors, including wholesale prices, investment in infrastructure and innovation, together with government green energy taxes. SSE has put their price hike down to an increase in wholesale prices, but has also passed part of the blame onto the government by suggesting that the price hikes are required to offset the government’s energy taxes. Will Morris, from SSE said:
We’re sorry we have to do this…We’ve done as much as we could to keep prices down, but the reality is that buying wholesale energy in global markets, delivering it to customers’ homes, and government-imposed levies collected through bills – endorsed by all the major parties – all cost more than they did last year.
The price hike has been met with outrage from customers and the government and has provided Ed Miliband with further ammunition against the Coalition’s policies. However, even this announcement has yet to provide the support for Labour’s plans to freeze energy prices, as discussed in the blog Miliband’s freeze. 
Customers with other energy companies are likely to see similar price rises in the coming months, as SSE’s announcement is only the first of many. A key question is how will the country provide the funding for much needed investment in the energy sector? The funds of the government are certainly not going to be available to provide investment, so the job must pass to the energy companies and in turn the consumers. It is this that is given as a key reason for the price rises.
Investment in the energy infrastructure is essential for the British economy, especially given the lack of investment that we have seen over successive governments – both Labour and Conservative. Furthermore, the government’s green targets are essential and taxation is a key mechanism to meet them. Labour has been criticized for its plans to freeze energy prices, which may jeopardise these targets. The political playing field is always fraught with controversy and it seems that energy prices and thus the cost of living will remain at the centre of it for many months.

Questions
- In what market structure would you place the energy sector?
- Explain how green taxes push up energy bills? Use a diagram to support your answer.
- Consider the energy bill of an average household. Using your knowledge and the articles above, allocate the percentage of that bill that is derived from wholesale prices, green taxes, investment in infrastructure and any other factors. Which are the key factors that have risen, which has forced SSE (and others) to push up prices?
- Why is investment in energy infrastructure and new forms of fuel essential? How might such investment affect future prices?
- Why has Labour’s proposed 20-month price freeze been criticised?
- What has happened to energy prices over the past 20 years?
- Is there now a call for more government regulation in the energy sector to allay fears of rises in the cost of living adversely affecting the poorest households?
For all households, energy is considered an essential item. As electricity and gas prices rise and fall, many of us don’t think twice about turning on the lights, cooking a meal or turning on the heating. We may complain about the cost and want prices brought down, but we still pay the bills. But, is there anything that can be done about high energy prices? And if there is, should anything be done?
The worlds of politics and economics are closely linked and Ed Miliband’s announcement of his party’s plans to impose a 20-month freeze on energy prices if elected in 2015 showed this relationship to be as strong as ever. The price freeze would certainly help average households reduce their cost of living by around £120 and estimates suggest businesses would save £1800 over this 20 month period. The energy companies have come in for a lot of criticism, in particular relating to their control of the industry. The sector is dominated by six big companies – your typical oligopoly, and this makes it very difficult for new firms to enter. Thus competition is restricted. But is a price freeze a good policy?
Part of the prices we pay go towards investment in cleaner and more environmentally friendly sources of energy. Critics suggest that any price freeze would deprive the energy sector of much needed investment, meaning our energy bills will be higher in the future. Furthermore, some argue this price freeze suggests that Labour is abandoning its environmental policy. Energy shortages have been a concern, especially with the cold weather the UK experienced a few years ago. This issue may reappear with price freezes. As Angela Knight, from Energy UK, suggests:
Freezing the bill may be superficially attractive, but it will also freeze the money to build and renew power stations, freeze the jobs and livelihoods of the 600,000-plus people dependent on the energy industry and make the prospect of energy shortages a reality, pushing up the prices for everyone.
There is a further concern and that is that large energy companies will be driven from the UK. This thought was echoed by many companies, in particular the British Gas owner Centrica, commenting that:
If prices were to be controlled against a background of rising costs it would simply not be economically viable for Centrica to continue to operate and far less to meet the sizeable investment challenge that the industry is facing…The impact of such a policy would be damaging for the country’s long-term prosperity and for our customers.
Share prices naturally fluctuate with global events and a political announcement such as this was inevitably going to cause an effect. But, perhaps the effect was not expected to be as big as the one we saw. 
Share prices for Centrica and SSE fell following the announcement – perhaps no great shock – but then they continued to fall. The market value tumbled by 5% and share prices kept falling. This has led to Ed Miliband being accused of ‘economic vandalism’ by a major shareholder of Centrica, which is hardly surprising, given the estimated cost of such a price freeze would be £4.5 billion.
The economic implications of such a move are significant. The announcement itself has caused massive changes in the FTSE and if such a move were to go ahead if Labour were elected in 2015, there would be serious consequences. While families would benefit, at least in the short term, there would inevitably be serious implications for businesses, the environmental policy of the government, especially relating to investment and the overall state of the economy.

The BBC has recently published the results of its third report on average ticket prices for football for the top ten divisions in the UK. These include all four professional leagues in England (The Premier League, The Championship, League 1 and League 2), the top division in English non-league football (Conference Premier), the 4 professional leagues in Scotland (The Scottish Premier, The Scottish Championship, Scottish League One, Scottish League Two) and the top league in women’s football (Women’s Super League). Most of the headlines have focused on evidence of falling ticket prices in the 4 professional leagues in England.
The BBC study focuses on four different categories of ticket.
– The most expensive adult season tickets
– The cheapest adult season tickets
– The most expensive adult match-day tickets
– The cheapest adult match-day tickets
The average price in each category is simply calculated as the price charged by each club in that category divided by the number of clubs. For example, the most expensive season ticket offered by Arsenal last year was £1955, whereas at Swansea it was £499. The average price was lower in all four categories for the three leagues in the English Football League (The Championship, League 1, League 2). For example, the price of the cheapest adult season tickets fell by 8.4% in the Championship, 1.6% in League 1 and 7.6% in League 2. Prices were also lower in three out of the four categories in the English Premier League (EPL). The only exception was the price of the cheapest adult season tickets which actually increased by 4.3%.
The overall trend in falling prices is in marked contrast to the previous year’s report that had found evidence of rising prices. For example the 2012 survey found that the average price of the cheapest adult match-day ticket increased by 11% on average across the EPL and EFL.
One factor that may be driving the apparent fall in prices in the English Football League is the falling attendances at games. Average attendance in 2012-13 was down 5% on the previous year – the second consecutive fall. It was 9% lower than in 2009-10 season. In complete contrast, attendance at EPL games were slightly up on the previous year and there were also record season ticket sales.
The increase in the average price of the cheapest adult season tickets in the EPL has received criticism from supporters groups. For example, The Football Supporters’ Federation called for far larger cuts in ticket prices, which they argued could have been funded by the big increase in the revenue from the latest TV deal. BskyB and BT paid a combined total of £3.018bn for the rights to show live games from the 2013-14 season to the 2015-16 season. This was an increase of £1.773bn on the previous deal. Malcolm Clarke, chair of the Football Supporters’ Federation, said
The Premier League has had an eye-watering increase in its media income. For example, they could knock £50 off the price of every single ticket of every single game for every single spectator in the Premier League this season and still have the same amount of money as they previously had.
Some have argued that it may also be in the commercial interests of the clubs to reduce prices. Professor Simon Chadwick from Coventry University commented that:
Lower prices and more fans can mean an increase in overall revenue, and there is also the secondary spend to consider: club merchandise, food and drink and so on.
However, care must be taken when interpreting this data because the report does not state how many fans actually pay the most expensive or cheapest price in each of the four categories. For example, the report found that Arsenal charged the highest price of £126 in the most expensive match-day ticket category. The club responded to this finding by stating that less than 100 people would actually pay this price at any given game!
Burton Albion was also reported as having the highest match-day ticket price of £30 for both League 1 and League 2. Once again the club responded by stating that only one or two of these tickets would be sold and car-parking, food and a programme were included in the price. Perhaps it would be more accurate to title the report “The average ticket price of the most expensive and cheapest seats for a football match”.
Some weighting system, such as that used to calculate the retail price index, would need to be used in order to obtain a more accurate picture of what is happening to average prices. It is possible that the price of tickets covered in the BBC report could be falling whilst the average price of all tickets could still be rising.

Valued by private investors at more than $10 billion, the future listing on the stock market of Twitter, is an eagerly anticipated event. The necessary forms have been submitted to the US Securities and Exchange Commission (SEC) ahead of the initial public offering (IPO). Twitter will be looking to avoid the mistakes made by Facebook when they were first listed in May last year. Twitter has also announced its intentions to purchase MoPub, which is a firm specialising in mobile advert exchanges.
So, what will this listing mean for Twitter? The public will now be able to purchase shares in Twitter, in much the same way as you can buy shares in RBS or Facebook. The financial performance of Twitter will come under much greater scrutiny from its shareholders, who will be interested in short term returns and long term stability. Becoming a public limited company will attract investors and is likely to provide a much larger scope for expansion for Twitter. However, as yet no details have been released on a likely date for the flotation or on the prices we can expect.
One thing Twitter will be trying to avoid is a repeat of the problems that beset Facebook and indeed of the problems that other public listings have created for giants such as Google, Zynga and Groupon. When Facebook moved to public ownership, its share prices initially fell below its IPO and subsequently Facebook lost more than half its value. More recent success in mobile advertising has restored the fortunes of this company, but Goldman Sachs, which is handling Twitter’s transition will be looking to avoid a similar occurrence. As Sam Hamadeh from PrivCo (a firm that gathers data on private companies) said:
Twitter will learn from Facebook’s flawed playbook and do the opposite … Unlike Facebook, which waited too long to IPO (until its growth rate decelerated), Twitter will IPO at just the right inflection point: while revenue grows in triple digits.
Twitter is a rapidly growing business, but still has significant scope for expansion and this move to public ownership may be just the thing. Setting the right IPO and the right date will be crucial, as a multitude of factors can and do affect the price of shares listed on the stock market. Twitter will also need to ‘focus on doing the right stuff’ to make a success of the listing and its purchase of Mopub looks to be a step in the right direction. For now, all we can do is speculate, but if the launch is successful, then the founders of Twitter are likely to bring in hundreds of millions of dollars each.
