4.5 Microeconomics Contestable Markets Flashcards
Contestable market
A market in which the existing firm makes only normal profit. The firm in the market perceives a potential threat from firms who might join the market.
Characteristics of contestable markets
No barriers to entry or exit, no sunk costs, have no competitive disadvantage compared with the incumber and have access to the same technology.
Sunk costs
The costs from setting up a business which cannot be recovered when the firm leaves the market.
Hit and run entry
Where a firm enters a market to take short run supernormal profits knowing it can exit without incurring costs.
Is a contestable market efficient?
Firms are forced to be more efficient where price= AC and make only normal profits or operating at the lowest point on the AC curve to reduce the threat from a rival. If also P=MC which would be both productively or allocatively efficient.
Normal profits
Where AC=AR costs including opportunity cost.
Supernormal profits
Where AR>AC.
Examples of contestable markets
Air B’n’B, Brewdog, small retailers, parcel deliveries
What does a contestable market depend upon?
Low sunk costs- not always guaranteed. Firms need to advertise and these costs will not be recouped. Also it depends how the incumbent firm operates- when a rival enters, it may lower production costs to force the rival out.
Incumbent firm
Firm already in the market.
Competition and Markets Authority

Bid rigging
An agreement between firms to set the prices when bidding for a contract.
Territorial Exclusivity

Resale price maintenance
Suppliers instructing sellers on the price they can sell the good for.
Nationalisation
The process of transforming private assets into public assets by bringing them under public ownership.
