Much of the east coast of England is subject to tidal flooding. One such area is the coastline around the Wash, the huge bay between Norfolk and Lincolnshire. Most of the vulnerable shorelines are protected by sea defences, usually in the form of concrete walls or earth embankments, traditionally paid for by the government. But part of the Norfolk shoreline is protected by shingle banks, which require annual maintenance.
Full government funding for maintaining these banks ended in 2013. According to new government rules, only projects that provide at least £8 of benefits for each £1 spent would qualify for such funding to continue. The area under question on the Norfolk cost of the Wash does not qualify.

Between 2013 and 2015 the work on the shingle banks is being paid for by the local council charging levies. After that, the plan is for a partnership-funding approach, where the government will make a (small) contribution as long as the bulk of the funding comes from the local community. This will involve setting up a ‘community interest company’, which will seek voluntary contributions from local residents, landowners and businesses.
Sea defences are a public good, in that it is difficult to exclude people benefiting who choose not to pay. In other words, there is a ‘free rider’ problem. However, in the case of the Wash shoreline in question, one borough councillor, Brian Long, argues that it might be possible to maintain the flood defences to protect those who do contribute while ignoring those who do not.
Not surprisingly, many residents and businesses argue that the government ought to fund the defences and, if it does have to be financed locally, then everyone should be required to pay their fair share.

On my commute to work on the 6th October, I happened to listen to a programme on BBC radio 4, which provided some fascinating discussion on climate change, growth, capitalism and the need for co-operation. With more countries emerging as leading economic powers, pollution and emissions continue to grow. Is it time for a green revolution?
The programme considers some ‘typical’ policies and also discusses some radical solutions. There is discussion on developing and developed nations and how these countries should be looked at in terms of compensation, entitlement and aid. Carrots and sticks are analysed as means of saving the planet and how environmental damage can be reduced, without adversely affecting the growth rate of the world economy. I won’t say any more, but it’s certainly worth listening to, for an interesting discussion on one of the biggest problems that governments across the world are facing and it is not going to go away any time soon.

The Office for National Statistics (ONS) reported that the quantity of retail sales in the UK was 3.9% higher in August than it had been in July. However strong price competition meant that the value of these sales increased by only 0.4%. What were the key factors driving the big increase in the quantity of sales? Was it simply the response of consumers to falling prices?
The data indicated that there was strong demand for goods associated with the housing market such as carpets, fridges and cookers. Spending on furniture increased very rapidly with sales rising by 24% over a 12 month period. Flat packed furniture proved to be particularly popular with consumers.
There was also strong demand for electrical goods and more specifically vacuum cleaners. The ONS estimated that a boom in the sale of vacuum cleaners in August was responsible for 25% of the increase in retail sales.
Why did the sales of vacuum cleaners increase so rapidly in August? Did UK households suddenly decide to keep their houses cleaner? The sales data shows that certain types of vacuum cleaners sold in much larger numbers than others.
For example, Tesco reported a 44% increase in the sales of 2,000 watt vacuum cleaners in the last two weeks in August while the Co-op reported an increase of 38%. Referring to the last weekend in August, the head of small domestic appliances at the on-line retailer ao.com stated that
We saw a huge surge in sales of corded vacuums over 1,600 watts over the weekend, with sales quadrupling.
There were also reports that a significant number of customers were buying more than one vacuum cleaner with these larger motors.
The key reason for the sudden surge in demand was the implementation of new regulations by the European Union as part of its energy efficiency directive. The ultimate objective of this directive is to reduce climate change. The specific policy that appears to have had such a big impact on consumers in the UK was the ban imposed on firms in the EU from making or importing vacuum cleaners that have motors above 1600 watts. This ban came into effect on the 1st September 2014.
A spokesperson for the consumer group Which? stated in August that
If you’re in the market for a powerful vacuum, you should act quickly, before all the models currently sell out. A Best Buy 2,200-watt vacuum costs around £27 a year to run in electricity – only around £8 more than the best scoring 1,600-watt we’ve tested.
The EU plans to reduce the maximum permitted wattage in vacuum cleaners to 900 watts in 2017. Restrictions have already been imposed on bigger electrical appliances such as televisions, washing machines and refrigerators. The EUs Ecodesign directive may also be extended to a range of smaller electrical appliances such as toasters and hair dressers in the future. It’ll be interesting to see if consumers respond in the same way to regulations imposed by the EU in the future.

Questions
- Using a demand and supply diagram, illustrate what has happened in the market for high wattage vacuum cleaners in August. Pay particular attention in your answer to the role of expectations.
- What did your previous diagram predict would happen to the price of high wattage vacuum cleaners in August? Did this in fact happen?
- A fully informed rational consumer may purchase a higher wattage vacuum cleaner if they consider that the improvement in cleaning performance is greater than the extra cost of purchasing and using the cleaner. Can you provide an economic rationale for banning the sale of these machines in these circumstances?

Officials from Rugby Union’s Aviva Premiership recently announced that the salary cap used by the league would increase from £4.76 million to £5.1 million per team for the 2015-16 season. It is not the only professional sports league to use this type of regulation. The NFL currently has a salary cap of $133 million/team while in the NBA it is set at $63 million/team. What is the rationale for placing restrictions on the amount an organisation can pay its employees? How do these caps work in practice?
A salary cap is a regulation that limits the amount that an organisation can pay its employees. Sanctions are usually imposed if the ceiling is broken.
It is hard to imagine this type of policy being introduced in most industries. For example there may have been a number of calls for much greater regulation of the big six firms in the energy market with the Labour party suggesting that prices should be frozen for 20 months. However in amongst all the calls for more intervention, nobody has suggested that limits should be placed on the wages that these firms pay their staff.
One example where the authorities are thinking of intervening on pay is the proposal by the European Union to introduce a cap on the size of bonuses that can be paid by firms in the banking industry. However this is more of a constraint on the method of remuneration rather than an absolute limit on the level of pay. If the policy was introduced there would be nothing preventing firms from increasing basic salaries in order to make up for any shortfall caused by the reduction in bonuses.
There is one sector of the economy where salary caps are widely used – professional team sports. There are a number of different ways they have been implemented. For example the Football Association once placed a limit on the amount that a club could pay an individual player. This was originally set at £4/week in 1901 and increased to £20/week before it was finally abolished in 1961.
In recent times it has been far more common for salary caps in professional sports leagues to place limits on the size of a team’s total wage bill rather than the amount that can be paid to an individual player. This is the case in the Aviva Premiership, the NFL and the NBA. Perhaps it would be more accurate to refer to these policies as a cap on payrolls rather than on salaries.
The Aviva Premiership gives the following 4 reasons for having the payroll cap that it first introduced in 1999:
|
|
| • |
To ensure the financial viability of the clubs; |
| • |
To ensure a competitive Aviva Premiership Rugby competition; |
| • |
To control inflationary pressures on clubs’ costs; |
| • |
To provide a level playing field for the clubs. |
It is claimed that the policy has helped the league to achieve these objectives as (a) more clubs are now breaking even and (b) compared with other rugby competitions it has the greatest number of games that finish with less than one score between the teams.
There are a number of different ways that a payroll cap can be implemented. With an absolute payroll scheme all the teams in the league, no matter what their size, face the same constraint. This is the policy adopted by the NFL, NBA and the Aviva Premiership. An alternative is to implement a percentage payroll cap. Examples of these can be found in League 1 and League 2 of the English Football League. League 1 teams can spend up to 60% of their turnover on wages while League 2 teams can spend up to 55% of their turnover on wages. Obviously this means that well supported clubs with a larger turnover can spend more on players’ wages than less well supported clubs with a smaller turnover.
Another way that payroll caps differ is whether they are ‘hard’ caps or ‘soft’ caps. With a ‘hard’ cap there are no exceptions to the scheme. All the teams’ payrolls must remain within the same limit set by the league officials. With a ‘soft’ cap the authorities identify some exceptions that enable clubs to exceed the limit. The payroll cap used in rugby union is an example of a soft cap and works in the following way.
There are a number of elements to the scheme:
|
|
| • |
The senior salary cap; |
| • |
Excluded players; |
| • |
The academy credits. |
The senior salary cap is the major part of the regulation and the Aviva Premiership announced that this would increase from £4.76 million per team in the current season to £5.1 million per team for 2015-16. The Academy credits enable teams to exceed this £5.1 million limit if they train and develop younger players. The teams have to prove that they have young players that meet the following criteria:
|
|
| • |
They are under the age of 24 before the season started; |
| • |
They joined the youth academy before their eighteenth birthday; |
| • |
They earn more than £30,000 per year. |
For a player who meets these conditions it is only their salary in excess of £30,000/year that is considered. For example if a young player was paid £50,000/year then only £20,000 of his wages would count towards the team’s payroll cap. The first £30,000 would not count. The Aviva Premiership recently announced that a home grown player credit would replace the academy credits. Under the new scheme the upper age limit will be removed and clubs can claim up to £400,000 in allowances. This means that teams could spend up to £5.5 million a year on wages if they train and develop younger players.
However other exceptions means that teams can exceed even this figure. The payroll cap arrangements allow teams to identify one player whose wages are not included when the payroll cap is calculated. In order to be nominated the exempted player has to meet certain criteria. In the 2015-16 season teams will be allowed to have two excluded players.
Sir Iain McGeechan has suggested that these changes will increase the effective salary cap to £7 million/year with some star players earning £1 million/season. However this would still be below the level of the basic salary cap in the French Rugby Union Super 14 League which is €10 million per season (approximately £8.5 million)

Every year thousands of entrepreneurs will have another great idea that is sure to take off and bring in millions of customers. However, most of these great ideas will turn into another business failure. But, in the case of Dropbox, it is multiple business failures that eventually created a huge success, giving hope to millions of budding entrepreneurs.
With 300 million users, the file sharing ‘Dropbox’ is certainly a success, estimated at a value of $10bn. But it didn’t happen immediately and was preceded by a few failures. So, what is the secret to success in this case? The co-founder of Dropbox, Drew Houston, said that it is all about providing something that customers want. In the case of Dropbox, customers are crucial: the more people use it, the easier it becomes for others to use it too, as it allows file sharing on a much larger scale. Perhaps here we have a case of network externalities.
With Dropbox people would tell their friends about it and collaborate. So when you go into work and work on a project with colleagues you recruit them in essence to become Dropbox users because you’re all working on a project together.
No doubt there are many other examples of businesses that have proved a success after several failed attempts. Providing customers with what they want, at the time when they need it is clearly a key ingredient, but so, it appears, is business failure. The following article from BBC News considers the rise of Dropbox.
Dropbox and the failures behind it BBC News, Richard Taylor (1/7/14)
Questions
- Customers are clearly crucial for any business to succeed. How can a new entrepreneur find out if there is a demand?
- Why was timing so important in the case of Dropbox?
- Given that customers can actually use Dropbox for free, how does this company make so much money?
- What are network externalities? Explain them in the context of Dropbox.
- Drew Houston says that ‘distribution’ is another key ingredient to success. What do you think is meant by this and how will it help create success?
