Topic 3.3.10
Students should be able to:
• Define contestability and understand how the threat of new
entry may influence behaviour and market performance of
existing firms.
• Understand the relationship between sunk costs and the
degree of contestability — examples may include banking,
airline industry and petrol retailing.
3. • Contestable markets are constantly changing!
• Can be seen at a local, regional, national and
international level
• In a contestable market, the number of firms & the size
distribution of firms is not considered to be important
• More focus given to credible threat of entry from rivals
• Almost all markets are contestable to some degree
• Technology is changing contestability
– E.g. Barriers to entry have lowered because of digital advances
– Many start-ups use the web as a platform to enter markets
• Contestable markets often show high dynamic efficiency
– challenger brands attacking established operators

13. Absence of sunk costs
Access to all available
technology
Low rate of existing
consumer loyalty Low barriers to entry
1. A pool of new
entrants who are
willing and ready to
enter the market –
e.g. app developers
2. No significant entry
or exit costs – lowers
the risk of market
entry
3. Equal access to
available industry

4. High rates of
customer churn
(switching)

20. Sunk Costs
1. Sunk costs cannot be recovered if a firm leaves
an industry
2. When sunk costs are high then a market
becomes less contestable
3. High sunk costs act as a barrier to entry of new
firms because they risk making significant losses
if they decide to exit the sector
4. In markets such as fast-food restaurants,
sandwich bars, hairdressing salons and local
antiques markets there are low sunk costs so
barriers to exit are low and contestability is high
21. Core Examples of Sunk Costs
1. Asset-write-offs – e.g. writing-off the value of plant and
machinery, stocks and the goodwill of a consumer brand
2. Closure or project cancellation costs including redundancy
costs, bad debts, contracts with suppliers and the penalty
costs from ending leases for property & equipment
3. The loss of business reputation and goodwill - a decision to
leave a market can seriously affect goodwill among previous
customers, not least those who have bought a product which
is then withdrawn and for which replacement parts become
difficult or impossible to obtain.
• A market downturn may be perceived as temporary and
could be overcome if and when the economic or business cycle
turns and conditions become more favourable

25. Key Concepts – Contestable Markets
Key concept Brief definition
Contestable Market
Where an entrant has access to all
production techniques available to
incumbents and entry decisions can be
reversed without cost
Hit and run entry
When a business enters an industry to
take advantage of temporarily high
(supernormal) market profits.
Sunk costs
Sunk costs cannot be recovered if a
business decides to leave an industry.
The existence of sunk costs makes a
market less contestable.
26. • Lidl is following a strategy of rapid organic growth
• Aldi - world’s leading limited assortment grocery, with
total sales of €61bn in 2013, followed by Lidl at €59bn
• Together, the two German discounters have more than
20,000 stores across Europe, the US and Australia. Lidl
is present in 26 European markets
• Majority of their products are own-label, rather than
brands - gives them purchasing power with suppliers.
• The range suppliers are asked to provide is narrower –
perhaps four to six products compared with 30-40 at a
large grocer – driving efficiencies and big volumes
Retail Contestability – Rise of Aldi & Lidl
27. Contestable Markets – Price and Profit
• The more contestable a market is, the more likely
that an allocatively efficient outcome is achieved
• The threat of entry affects the behaviour of firms
• Often smaller disruptive businesses challenge the
monopoly power of existing businesses
• The threat of entry is as important as actual
competition

33. • The threat of new competition is often a
powerful an influence on the behaviour of
existing established firms
• A highly contestable market will resemble perfect
competition, regardless of the number of firms,
since incumbents behave as if there were intense
competition!
• Competition policies that help to open up the
market to new suppliers or persuade consumers
to switch in greater numbers help to increase
contestability
