What is Market Effiency
Market efficiency also occurs when resources are allocated to maximised society’s benefits and is measured by the total surplus.
What does demand curve show?
A demand curve is a willingness to pay curve. It reflects the maximum price that a consumer will pay for a good. The demand curve also reflects the marginal benefits a consumer gets from a good. It therefore is also a marginal benefit curve.
What does supply curve show?
The supply curve reflects the minimum price that producers are willing to sell their products.
It shows each price and quantity that the supplier or producers is willing to accept
What is producer surplus and give an example?
Producer surplus is the difference between what a producer is willing to receive and what they actually receive.
How to find total surplus
TS = CS + PS.
What is the most market effiecient?
Economic efficiency occurs when total surplus is at a maximum. Total surplus is only maximised at equilibrium
4 main types of market failure?
Market Power
Externalities
Public Goods
Common Goods
MEPC
What is Market failure
Market failure occurs when resources are not allocated efficiently.
Compettive Market characterisitcs?
large number of firms, little barriers to entry and exit, and little product differentiation.
Example of barrier to entry?
Technolgoical adavance, patent, controlling of scare resource
Market Power exists when+example and explain
There are a small number of firms
Firms use product differentiation
There are barriers to entry to restrict competition. An example is Synergy (power) or Australia Post
What happens when there is market power?
When there is market power, there is an incentive for firms to collude. This reduces competition, increases prices and reduces output. This will decrease economic welfare for society.
What is Market Power

What is negative externalities?
When a negative externality occurs, the social cost (cost to society) is higher than the private costs.
Effects of tax on market?
Decrease CS AND PS and adds DWL
Effects of subsidy on market
CS AND PS increases as well as DWL reduction
