<strong>Price</strong> <strong>discrimination</strong><br />
University tuition fees<br />
William Bohanna discusses whether a university can practise third-degree<br />
price <strong>discrimination</strong> with the new fee structure<br />
There has been much <strong>co</strong>ntroversy over<br />
the government’s plans to lift the cap on<br />
university tuition fees. Ministers have voted<br />
to allow universities in England to charge<br />
tuition fees up to £9,000 per year. Following<br />
re<strong>co</strong>mmendations by Lord Browne — who<br />
led the independent review of higher education<br />
funding — this measure <strong>co</strong>mes in light<br />
of budget cuts to aid the national e<strong>co</strong>nomy<br />
and UK budget deficit. However, has the<br />
government made the market for university<br />
education more accessible to practise thirddegree<br />
price <strong>discrimination</strong>?<br />
As e<strong>co</strong>nomics students, it is always good<br />
to question the way in which price <strong>discrimination</strong><br />
can be carried out in various<br />
markets, and as such whether the market<br />
for higher education <strong>co</strong>uld practise price<br />
<strong>discrimination</strong>.<br />
What is price <strong>discrimination</strong>?<br />
When a firm has power over a market (a<br />
degree of monopoly power), it may be able<br />
to increase its total profits by charging different<br />
prices for the same good or service<br />
in different markets. This is known as price<br />

<strong>discrimination</strong>, which is selling the same<br />
product or service at different prices in situations<br />
where such differences do not result<br />
from differences in <strong>co</strong>sts.<br />
<strong>Price</strong> <strong>discrimination</strong> can take advantage<br />
of the <strong>co</strong>ncept of <strong>co</strong>nsumer surplus.<br />
Consumer surplus is the difference between<br />
what a <strong>co</strong>nsumer is willing to pay for a<br />
good or service and the price they actually<br />
pay. It represents the excess, or surplus,<br />
Consumer surplus = ape.<br />
The demand curve represents what people are willing to pay<br />
for a good. It represents their valuation of the satisfaction that<br />
they will receive from the <strong>co</strong>nsumption of the good. As each<br />
person is different some will value the same good differently.<br />
P is the equilibrium or market price. It is what all <strong>co</strong>nsumers<br />
must pay if they want this good. However, there are some<br />
people who would have been willing to pay more (a to e on<br />
the demand curve). These individuals will experience <strong>co</strong>nsumer<br />
surplus, i.e. excess benefit over and above what they have paid<br />
for. The total of all these individual <strong>co</strong>nsumer surpluses is equal<br />
to the area ape between the demand curve and the price line.<br />

Figure 2 <strong>Price</strong> <strong>discrimination</strong><br />
satisfaction derived from the purchase over<br />
and above what has been paid for (Figure 1).<br />
<strong>Price</strong> <strong>discrimination</strong> occurs due to the<br />
downward sloping nature of the demand<br />
curve — there are always some people who<br />
are willing to pay more for a good or service<br />
than others.<br />
Firms tend to charge one price — the<br />
equilibrium price. As a result, a lot of people<br />
buy goods and services at prices below that<br />
which they are willing to pay. <strong>Price</strong> <strong>discrimination</strong><br />
is a method that firms use to appropriate<br />
all or part of this <strong>co</strong>nsumer surplus in<br />
the form of revenue.<br />
Figure 2 shows how the practice of price<br />
<strong>discrimination</strong> allows for an increase in<br />
revenue of the price discriminator and an<br />
appropriation of <strong>co</strong>nsumer surplus. Any<br />
private sector firm would enjoy this situation,<br />
as the potential for increasing profits<br />
is very motivating. This <strong>co</strong>uld readdress the<br />
funding problems that struggling universities<br />
have faced for many years.<br />
Ac<strong>co</strong>rding to theory, there are three levels<br />
of price <strong>discrimination</strong> that a firm <strong>co</strong>uld<br />
follow.<br />
First-degree price <strong>discrimination</strong>: this<br />
is where firms persuade all <strong>co</strong>nsumers in the<br />
market to reveal the price they are willing to<br />
pay. Here, the firm would be appropriating<br />
the entire <strong>co</strong>nsumer surplus — by looking<br />
at the particular point on the demand curve<br />
<strong>co</strong>rresponding to each individual. This<br />
<strong>co</strong>uld not be used in the higher education<br />
market, as it would mean each student effectively<br />
bidding for their place. This would be<br />
time <strong>co</strong>nsuming and would favour richer<br />
students, so it tends to occur only where the<br />
market is very small — sealed bid auctions,<br />
for example.<br />
Se<strong>co</strong>nd-degree price <strong>discrimination</strong>:<br />
this is where the firm sells different quantities<br />
of a good at different prices to the same<br />
<strong>co</strong>nsumer. Or, <strong>co</strong>nsumers pay different<br />
September 2011<br />
prices based on their <strong>co</strong>nsumption level.<br />
This <strong>co</strong>uld not occur in the higher education<br />
market because the quantities for a degree<br />
are roughly the same, but it does occur in<br />
energy markets — high-level <strong>co</strong>nsumers,<br />
such as firms, may be charged different<br />
prices per unit <strong>co</strong>mpared to small users,<br />
such as households.<br />
Third-degree price <strong>discrimination</strong>: this<br />
is where the firm sells identical products at<br />
different prices to different groups of <strong>co</strong>nsumers<br />
(known as market segments). The<br />
following list shows how a market can be<br />
segmented:<br />
■■<br />
Time — peak and off-peak prices<br />
(airlines and rail <strong>co</strong>mpanies)<br />
■■<br />
Age — lower fares for children, students<br />
and OAPs on buses and trains<br />
■■<br />
Location — bus <strong>co</strong>mpanies often charge<br />
different prices in different parts of the<br />
<strong>co</strong>untry<br />
■■<br />
In<strong>co</strong>me — people on low in<strong>co</strong>mes can<br />
often get <strong>co</strong>ncessionary fares<br />
Practising price <strong>discrimination</strong><br />
Could the higher education market practise<br />
third-degree price <strong>discrimination</strong> if it met<br />
certain <strong>co</strong>nditions? There are four <strong>co</strong>nditions<br />
that must be met for third-degree price<br />
<strong>discrimination</strong> to occur:<br />
1 The firm must be a monopolist — if there<br />
are other firms in the market then they can<br />
undercut the high price and take away customers<br />
from the price discriminator.<br />
2 The monopolist must be able to split<br />
the market into easily distinguishable and<br />
distinct groups of buyers, otherwise how<br />
can it tell who is willing to pay a high or a<br />
low price?<br />
3 The monopolist must be able to keep<br />
the market segments separate at a relatively<br />
low <strong>co</strong>st. This avoids arbitrage — where<br />
buyers in low-priced segments undercut the<br />
monopolist by reselling the product in the<br />
high-price segment at a lower price. If the<br />
<strong>co</strong>sts of keeping the markets separate are<br />
high then this will negate the extra revenue<br />
earned from the high-priced segment.<br />
4 Each market segment must face different<br />
demand curves, i.e. the elasticity of the<br />
buyers must differ — if it were the same the<br />
monopolist <strong>co</strong>uld not charge different prices.<br />
For a university to practise third-degree<br />
price <strong>discrimination</strong>, these <strong>co</strong>nditions must<br />
be met.<br />
Meeting the <strong>co</strong>nditions<br />
1 The university as a monopolist? The<br />
university offering degree programmes from<br />
their institution is effectively a monopolist<br />
for that set of degree programmes, as no<br />
other university can offer this degree from<br />
this institution. Therefore, the university<br />
has monopoly power over its degree programmes.<br />
Other universities will be offering<br />
similar <strong>co</strong>urses but if you want to do the<br />
degree at a certain university then you have<br />
no choice, and as such the university has<br />
gained a monopoly power.<br />
2 Can the university split the market<br />
into distinct groups of buyers? The<br />
answer to this <strong>co</strong>ndition effectively occurs in<br />
the UCAS application system. For example,<br />
a university <strong>co</strong>uld offer an e<strong>co</strong>nomics with<br />
mathematics degree and an e<strong>co</strong>nomics with<br />
Latin American studies degree. Depending<br />
on the number of applicants that each<br />
degree <strong>co</strong>urse attracts, the university has two<br />
groups of buyers. Therefore, the university<br />
can easily split the market and applicants<br />
into distinct groups of buyers: e<strong>co</strong>nomics<br />
with mathematics applicants and e<strong>co</strong>nomics<br />
with Latin American studies applicants. This<br />
means that the university has two groups of<br />
buyers for a degree from their university.<br />
3 Can the university keep the different<br />
market segments separate at a relatively<br />
low <strong>co</strong>st? Again the answer to this <strong>co</strong>ndition<br />
occurs in the UCAS application system.<br />
As this is an online system, the university<br />
can keep these two markets of e<strong>co</strong>nomics<br />
with mathematics applicants and e<strong>co</strong>nomics<br />
with Latin American studies applicants<br />
separate at little or no <strong>co</strong>st because this<br />
market does not interact on a face-to-face<br />
level, and <strong>co</strong>vers the whole globe in terms of<br />
applications.<br />
4 Does each market segment face<br />
different demand curves? Effectively yes,<br />
if we assume that we have the two different<br />
markets for degree programmes at a<br />
university of e<strong>co</strong>nomics with mathematics<br />
9
ZOE/FOTOliA<br />
Rail travel is subject to third-degree price<br />
<strong>discrimination</strong><br />
applicants and e<strong>co</strong>nomics with Latin<br />
American studies applicants, then it would<br />
be fair to say that each market segment<br />
<strong>co</strong>uld face a different elasticity of demand.<br />
E<strong>co</strong>nomics with Latin American studies<br />
applicants face inelastic price elasticity of<br />
demand (PED) (due to this being a more<br />
unique <strong>co</strong>mbination with a fewer amount of<br />
substitutes) and the e<strong>co</strong>nomics with mathematics<br />
applicants face a relatively elastic<br />
PED (due to this being a more <strong>co</strong>mmon<br />
<strong>co</strong>mbination with a large amount of substitutes).<br />
How would this work?<br />
Let us assume a monopolist at a particular<br />
university (Figure 3). There are two clearly<br />
definable market segments:<br />
E<strong>co</strong>nomics and<br />
mathematics applicants<br />
■■<br />
E<strong>co</strong>nomics with Latin American studies<br />
applicants. This will have inelastic PED.<br />
■■<br />
E<strong>co</strong>nomics with mathematics applicants.<br />
This will have elastic PED.<br />
The segments are easy to keep apart, as<br />
it is difficult to transfer or change an applicant’s<br />
preference for a university place.<br />
For each segment we can identify the<br />
demand curve (AR) and therefore the MR<br />
curve. If the two segments were aggregated,<br />
then the market demand curve would be<br />
produced. On the market diagram, we can<br />
draw the <strong>co</strong>st curves — which are the same<br />
in each market segment (by definition price<br />
<strong>discrimination</strong> does not arise due to <strong>co</strong>st<br />
differences).<br />
The university maximises profits at Q M<br />
where MC=MR. If the university was to<br />
E<strong>co</strong>nomics and Latin American<br />
studies applicants<br />
charge a single price, marginal revenue<br />
would be lower for e<strong>co</strong>nomics with Latin<br />
American studies than for e<strong>co</strong>nomics with<br />
mathematics, so it would increase profits<br />
if the university was to charge a higher<br />
price (P P<br />
) and take fewer e<strong>co</strong>nomics with<br />
Latin American studies applicants and take<br />
more mathematics applicants at a lower<br />
price (P O<br />
) where MR is equalised for the<br />
two groups. This would be with Q o<br />
mathematics<br />
and Q P<br />
Latin American applicants.<br />
Notice that:<br />
Q M<br />
= Q O<br />
+ Q P<br />
If we extend the line showing the output<br />
level in each segment up to the AR or D<br />
curve, then we can read off the price for that<br />
segment. Notice the e<strong>co</strong>nomics with Latin<br />
American studies applicants segment has<br />

higher prices (and more inelastic demand)<br />
than the e<strong>co</strong>nomics with mathematics<br />
applicants segment.<br />
The line showing the level of AC can also<br />
be extended across the segments, as by definition<br />
price <strong>discrimination</strong> does not arise<br />
due to <strong>co</strong>st differences. From this we can<br />
determine the level of supernormal profits<br />
in each segment.<br />
If the elasticities were the same in each<br />
segment the demand (AR) curves would<br />
be the same and therefore MR, prices and<br />
profits would also be the same.<br />
Conclusion<br />
By reviewing these <strong>co</strong>nditions, it would be<br />
possible for a university to practise thirddegree<br />
price <strong>discrimination</strong>. However,<br />
the government has stated that in order<br />
for a university to charge a higher price it<br />
must meet certain <strong>co</strong>nditions. Universities<br />
wanting to charge more than £6,000 would<br />
have to undertake measures — such as<br />
offering bursaries, summer schools and<br />
outreach programmes — to en<strong>co</strong>urage<br />
students from poorer backgrounds to apply.<br />
Therefore, this would alter the nature of the<br />
degree <strong>co</strong>urse and so would differentiate the<br />
service and not meet the definition of price<br />
<strong>discrimination</strong>.<br />
In addition, there is the central problem<br />
of university fees being inequitable for<br />
poorer students and universities minister<br />
David Willetts has said that universities will<br />
only be allowed to charge fees of £9,000 in<br />
‘exceptional circumstances’, for example if<br />
they had high teaching <strong>co</strong>sts or if they were<br />
offering an intensive 2-year <strong>co</strong>urse.<br />
Universities charging more than £6,000<br />
will have to <strong>co</strong>mmit to ‘access agreements’,<br />
negotiated with the Office For Fair Access<br />
(Offa), to <strong>co</strong>mmit them to programmes to<br />
recruit students from poorer backgrounds.<br />
Therefore, the final answer to the question<br />
of whether a university <strong>co</strong>uld practise<br />
price <strong>discrimination</strong> is quite simply no,<br />
but this does not mean that they would not<br />
want to. The age-old problem facing universities<br />
and the government is that demand for<br />
university places outreaches supply causing<br />
a shortage, so perhaps these increased fees<br />
are a way of dealing with that shortage in<br />
order to reduce demand? Either way, universities<br />
will not be able to take advantage of<br />
this measure in the form of price <strong>discrimination</strong><br />
and its revenue generating benefits.<br />
Review notes<br />
1 The new system for funding higher<br />
education through student tuition fees<br />
has caused widespread <strong>co</strong>nsternation and<br />
<strong>co</strong>ntroversy.<br />
2 <strong>Price</strong> <strong>discrimination</strong> can take place in<br />
markets that have certain characteristics. It<br />
involves setting different prices to different<br />
<strong>co</strong>nsumers for what is substantially the<br />
same product.<br />
3 Firms that practise price <strong>discrimination</strong><br />
are able to increase their profits at the<br />
expense of <strong>co</strong>nsumer surplus.<br />
4 There are different levels of price<br />
<strong>discrimination</strong> possible, depending on the<br />
characteristics of the market.<br />
5 If the price elasticity of demand differs<br />
for some university programmes then there<br />
may be s<strong>co</strong>pe for price <strong>discrimination</strong> to<br />
be used, although the <strong>co</strong>nditions imposed<br />
on universities wanting to charge a price<br />
above £6,000 may make it more difficult to<br />
implement.<br />
