Market Failure
and
Government
Intervention
Why does the government
intervene?

The free market is not always able to achieve
allocative efficiency. – Market Failure
An allocative efficient point is where
All resources are allocated to their most efficient use
All markets are in equilibrium
The economy is operating on its production possibility curve.
It is not possible to make someone better off without making
someone else worse off (Society’s well being is maximised)
This situation is also called Pareto efficiency
We will be looking at situations where it is possible to make
someone better off without making someone else worse off.
This is when governments intervene in the market.
Conditions for the market to
achieve allocative efficiency

Requires clear price signals
There must be
 Perfect Competition
 Perfect Information
 Perfect Mobility
 Consumer Sovereignty
 No Externalities or public goods
Reading Price Signals
Market Failure

Market Failure can occur from any
of the following
 The
existence of imperfect market
structures
 Externalities
 Public Goods
 Merit and Demerit goods
 Situations where the market leads to
inequitable (unfair) outcomes
Market Failure

Markets can fail in a number of ways

Some products may be under produced or not
produced at all. ie parks

Some products may be produced or over
produced but are not wanted by society


The production and consumption of some
products affect third parties.


ie drugs
ie pollution and smoking cigarettes.
The distribution of market income may not
enable all citizens to participate meaningfully
in society
Market Failure

Market failure provides governments
with the reason to intervene in the
economy or in particular markets
that are failing.

Government intervention aims to
overcome the failure of markets to
move towards a more allocatively
efficient position

Government Intervention

Four functions of the government
1. Legislative/Regulator Role
•
Legal Framework
•
•
Promoting Competition
•
•
Providing a framework so buyers and sellers know their
rights and obligations – enables fair dealing. Legal
system used to clarify, define and enforce property
rights.

Correcting for externalities
Government Intervention
2. Allocative Role
Governments allocate resources that the market
fails to produce in sufficient quantities
3. Distributive Role
Governments aim to promote equity (fairness)
This may be done through redistribution of
incomes
4. Stabilisation Role
Government aims to provide a stable economic
environment

Ownership/
Provision
Effect/ what it is Best for:
Lowering the price to encourage the production
and use of certain products. More resources are
Lowers the cost of production
allocated to a good/service than would be provided
by the free market.
Raises the price to discourage the production and
Increases the cost of
use of certain products. Pay for some of the costs
production
imposed on society as a result of the product being
consumed
Reduces Incomes
More direct effect than
taxes or subsidies
Redistribution of incomes
from “rich to poor”
Situations where its not
socially desirable for provision
to be in private ownership.
Providing G&S not
sufficiently provided by the
free market
Reduces demand. Progressive taxation narrows the
gap between rich and poor and reduces inequality
of income
Limit or prohibit the production or
consumption of certain products. Enforce the
production or consumption of certain products
Addressing income inequality in form of social
welfare benefits and income support.
