2. At the end of the lessons, students should:
Understand the key characteristics of
oligopolistic market structures.
Understand the makeup of one industry and be
able to comment on the extent to which it
represents characteristics of an oligopolistic
market structure .

13. Market forms can often be classified by their concentration ratio. Listed, in
ascending firm size, they are:
Perfect competition, with a very low
concentration ratio.
Monopolistic competition, below 60% for the
five-firm measurement.

24. Despite changes in costs of production,
oligopoly prices appear to remain at a
constant level
Consider petrol prices…. Very rarely different
within a geographical area… collusion or
market forces?
25.
26. Oligopolies do compete against each other -
known as non –collusive behaviour.
However, there is an incentive to collude.
Formal collusion -
is where firms set up an
agreement between each other – they create
a cartel!
28. This is not illegal
It is where competitive firms monitor each
other’s behaviour closely and refrain from
competing on price.
This is often seen as price leadership where
competitors follow the dominant firm’s lead.
29. Where a few firms dominate they could set
an agreement on price, quantities for supply,
service standards etc
The collusion restricts output
The collusion raises prices
The collusion raises abnormal profits
30. The Organisation of the Petroleum Exporting Countries (OPEC) is a permanent
intergovernmental organisation, currently consisting of 12 oil producing and
exporting countries, spread across three continents America, Asia and Africa.
The members are Algeria, Angola, Ecuador, the Islamic Republic of Iran, Iraq,
Kuwait, the Socialist People’s Libyan Arab Jamahiriya, Nigeria, Qatar, Saudi
Arabia, United Arab Emirates & Venezuela.
The organisation’s principal objectives are:
1. To co-ordinate and unify the petroleum policies of the Member Countries and
to determine the best means for safeguarding their individual and collective
interests;
2. To seek ways and means of ensuring the stabilisation of prices in international
oil markets, with a view to eliminating harmful and unnecessary fluctuations; and
3. To provide an efficient economic and regular supply of petroleum to consuming
nations and a fair return on capital to those investing in the petroleum industry.
31. Typically, cartel members may agree on:
prices Confess your cartel:
Individuals can be sent to prison
output levels for up to five years and businesses
discounts can be fined up to 10 per cent of
worldwide turnover.
credit terms
which customers they will supply
which areas they will supply
who should win a contract (bid rigging).
