Chap 23 Flashcards
Define Market Structure
the conditions which exist in a market including the number of firms
Define Competitive market
A market with a number of firms that compete with each other
Characteristics of a competitive market
The more competition there is, the more sellers and buyers there are
Each firm has a small share of the market/ small amount of the total market supply
Change in output of one firm has no effect on price
Relatively free entry & exit from the market
Define normal profit
The minimum level of profit required to keep a firm in the industry in the long run
Define Supernormal profit
Profit above that needed to keep a firm in the market in the long run
Behaviour of competitive markets when demand rises (/fall)
When demand rises; supernormal profit
This attracts more firms into joining the market
; Supply increases and prices lower
So the supernormal profit becomes normal
How do competitive firms promote efficiency?
Whichever firm responds quickly to change in demands gain a competitive advantage and earn higher profits
The threat arises because any inefficient firm that produces at a high cost will be driven out of the market.
Define Monopoly
A market with a single supplier
How do governments define a Monopoly/ Pure Monopoly/ Dominant Monopoly
Monopoly: 25% or more share
Dominant Monopoly: 40% share
Pure Monopoly: 100% share
Characteristics of a monopoly
• The firm is the industry ( 100% share of the market )
• High barriers to entry and exit
• Price maker- Its output is the industry’s output and so changes in its supply affect the market price
Why do monopolies arise?
- May develop over time (driven out rival firms and captured the whole of the market)
- Mergers and takeovers
- May exist from the start ( May own everything/ granted monopolistic powers by a government, which makes it illegal for other firms to enter the market )
Define Barrier to entry
anything that makes it difficult for a firm to start producing the product.
Define Barrier to exit:
anything that makes it difficult for a firm to stop making the product.
Why do monopolies continue?
Existence of barriers to entry and exit
Types of barrier of entry
- Legal barrier (in the form of a patent or a government act)
- Scale of production ( Large scale= low unit cost/ New firm= higher unit costs)
- Expensive to set up a new firm (if large capital equipment is required)
- Creation of brand loyalty through branding and advertising
- Monopoly’s access to resources and retail outlets.
