TYPES OF MARKET
2 MAIN TYPES
Perfect markets: do not exist in the real world
Imperfect markets: do not have any of the
characteristics of a perfect market. 4 types:
Monopoly
Oligopoly
Monopolistic
Monopsony
competition
PERFECT COMPETITION (MARKET)
Characteristics:
Large
number of firms – firms are price takers
Large number of buyers
Freedom of entry and exit
Perfect knowledge
Homogeneous products
MONOPOLY
Only one dominant firm.
The strength of any monopoly is determined by the
barriers to entry and the availability of substitutes.
They can charge above the normal price but don’t
have a free reign on what they can charge as there
will be a limit to what consumers will pay.
A monopoly that is too powerful may be
investigated by the government.
A monopoly is any firm that holds more than 25%
of a market.
OLIGOPOLY
The market here is dominated by a few large firms.
Markets that have this structure are soap powder,
supermarkets and petrol.
A firm with two dominant firms are called a
DUOPOLY.
Each firm has a branded or differentiated product.
It has a lot of influence in the market and can affect
its own and competitors’ market share.
To expand or maintain market share, firms will tend
to use non-price methods.
This can include advertising or branding.
Competing on price can lead to costly price wars
which is not good for business.
Firms sometimes in this type of market will collude to
fix prices, limit output or share out a market.
This is called a CARTEL.
MONOPOLISTIC COMPETITION
There are a large number of firms but each firm
produces a branded or differentiated product.
Each firm has a bit of control over price and its
market share.
There are weak barriers to entry.
Examples: restaurants, taxi businesses, hairdressers.
MONOPSONY
This is a market where there is only one buyer.
The buyer has a huge amount of power to dictate
price, product, design and delivery.
Supermarkets have a degree of monopsony power
over many of their suppliers.
PRODUCT DIFFERENTIATION
This is when suppliers try to create differences
between their products and those of the
competition.
Real differences include: design and quality
Imaginary differences include: advertising and
brand image.
BARRIERS TO ENTRY
These prevent any potential competitors from
getting into an industry.
They can either be deliberate or natural.
DELIBERATE BARRIERS
Marketing Barriers
High
spending on advertising can create a strong
brand image and loyalty, which new firms will find hard
to overcome.
eg
washing powder, breakfast cereals
Restrictive Trade Practices
A
strategy that restricts competition
Refusing
to sell to a retailer who buys from a rival
Refusing to sell unless they buy the whole range
Using predatory pricing to drive out competition
NATURAL BARRIERS
Capital costs
Entry
costs to some industries are very high.
Eg car manufacturing.
Sunk costs
These
are costs that can’t be recovered if
they firm fails. Can include advertising costs
or R&D.
Economies of Scale
Large
firms can gain huge economies of scale that new
entrants will find hard to compete with as existing firms
will have lower average cost.
Legal barriers
The
law can prevent new entrants to a market.
Examples include: patents and copyrights.
PRICING
PERFECT MARKETS
The price here is determined by the interaction of
demand and supply.
Each firm has to accept the equilibrium price for
their market.
Each firm is a PRICE TAKER.
IMPERFECT MARKETS
Firms in these markets can adopt a number of
strategies.
The decision on what to price is determined by how
much competition there is.
Fall into two groups:
COST-BASED PRICING
Cost-plus pricing
Price
is set by working out the AC and adding a mark
up for profit.
E.g.
AC is £1 and mark up is 10% then the price would
be £1.10.
Firms
with little competition can use this method
Advantages to Cost-Plus Pricing
It
is a very quick and easy method
Ensures
sales revenue will cover TC and make the firm
profits
Disadvantages of Cost-Plus Pricing
Fixed
mark-up could be a problem if new competition
was to enter the market
Contribution (marginal cost) Pricing
Price
is set to cover VC.
As
long as price more than covers VC a contribution will
be made towards FC.
If
enough orders are received so that contribution
equals FC then the firm will break-even.
If
contribution is greater than FC then profit is made
Advantages of Contribution Pricing
More
flexible than cost-plus
Pricing
of products can take into account competitors
prices and demand by customers
Can
be used during poor trading, so long as VC are
covered and a contribution is made to FC
CUSTOMER-ORIENTATED PRICING
Competition-based Pricing
When
there is strong competition firms may base their
price on what other firms in the market are charging.
There
may a price leader, who sets their price and the
rest of the market follows e.g. petrol
Penetration Pricing
New
entrants will set a price below existing suppliers to
gain a foothold in the market
The
hope is that consumers will become loyal to the
brand and continue to buy when the price is increased.
Predatory Pricing
Used
by existing firms to push out competition from the
market.
The
firm will lower their prices so that new entrants will
not be able to cover its covers.
Existing
firm covers its lost by CROSS-SUBSIDISING.
MONOPOLY PRICING
Charging what the market will bear
Suppliers
of unique products can charge the highest
price they think consumers will pay
Psychological Pricing
Products
may be priced above competition to create
the idea of better quality.
Price Skimming
Suppliers
of new products may charge a high price to
begin with in order to maximise revenues before
competitors enter the market.
Price Discrimination
Firms
over the same product but over different prices to
different types of consumers.
