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)

Questions

  1. Draw a diagram to illustrate the impact of a salary cap on a perfectly competitive market and explain your answer.
  2. Which teams in the Aviva Premiership would be in favour of the increase in the salary cap and which teams would be opposed? Explain your answer.
  3. Do you think that an absolute or percentage salary cap would be more effective at maintaining competitive balance in a league? Which teams would be more in favour of an absolute salary cap?
  4. Why do think some leagues have introduced a ‘soft’ rather than a ‘hard’ salary caps?
  5. To what extent do you think that salary/payroll caps are consistent with European single market principles about the free movement of people?
  6. Officials from the Aviva Premiership provide the clubs with a long list of payments which must be counted as part of a player’s salary. These include holiday costs, school fees, payment for off-field activities on behalf of the club, payments in kind and signing on fees. Why do you think that the authorities provide such a large list?
  7. Find out the criteria that must be met in order for a player to be exempted from the team’s payroll calculations. Provide some reasons why you think these criteria were used.

Many people are attracted to work in the private sector, with expectations of greater opportunities for promotion, more variation in work and higher salaries. However, according to the Office for National Statistics, it may be that the oft-talked-of pay differential is actually in the opposite direction. Data from the ONS suggests that public sector workers are paid 14.5% more on average than those working in the private sector.

As is the case with the price of a good, the price of labour (that is, the wage rate) is determined by the forces of demand and supply. Many factors influence the wages that individuals are paid and traditional theory leads us to expect higher wages in sectors where there are many firms competing for labour. With the government acting as a monopsony employer, it has the power to force down wages below what we would expect to see in a perfectly competitive labour market. However, the ONS data suggests the opposite. What factors can explain this wage differential?

Jobs in the public sector, on average, require a higher degree of skills. There tend to be entry qualifications, such as possessing a university degree. While this is the case for many private-sector jobs as well, on average it is a greater requirement in the public sector. The skills required therefore help to push up the wages that public-sector workers can demand. Another explanation could be the size of public-sector employers, which allows them to offer higher wages. When the skills, location, job specifications etc. were taken into account, the 14.5% average hourly earnings differential declined to between just 2.2% and 3.1%, still in favour of public-sector workers. It then reversed to give private-sector workers the pay edge, once the size of the employer was taken out.

Further analysis of the data also showed that, while it may pay to be in the public sector when you’re starting out on your career, it pays to be in the private sector as you move up the career ladder. Workers in the bottom 5% of earners will do better in the public sector, while those in the top 5% of earners benefit from private-sector employment. The ONS said:

Looking at the top 5%, in the public sector earnings are greater than £31.49 per hour, while in the private sector, the top 5% earn more than £33.63 per hour… The top 1% of earners in the private sector, at more than £60.21 per hour, earns considerably more than the top 1% of earners in the public sector, at more than £49.65 per hour.

The data from the ONS thus suggest a reversal in the trend of average public-sector pay being higher than private sector pay, once all the relevant factors are taken into account.

This will naturally add to debates about living standards, which are likely to take on a stronger political slant as the next election approaches. It is obviously partly down to the public-sector pay freeze that we saw in 2010 and also to a reversal, at least in part, of the previous trend from 2008, where public-sector pay had been growing faster than private-sector pay. However, depending on the paper you read or the person you listen to, they will offer very different views as to who gets paid more. All you need to do in this case is look at the titles of the newspaper articles written by the Independent and The Telegraph! Whatever the explanation, these new data provide a wealth of information about relative prospects for pay for everyone.
