Market Failure
where the free market does not make the best use of scarce resources. |
- where the outcomes of a free market differ from the socially optimal outcomes. |
When does 'Market Failure' occur?
occurs when the free market fails to efficiently allocate goods and services. |
Reasons for Market Failure
1. Externalities |
2. Public Goods |
3. Asymmetric Information |
4. Abuse of Market Power |
|
|
Externalities
1. Positive Externality |
where the side effects have a positive impact and provide benefits to third parties. |
|
2. Negative Externality |
where the side effects have a negative impact and impose costs to third parties. |
Reasons of Market Failure: Externalities
MSC (marginal social cost) is above the MPC (marginal private cost). |
|
|
- MPC is the Supply Curve and DD is the demand curve |
|
Equilibrium: Supply = Demand |
|
Social Optimum output level is achieved at Q’ where MSC = DD = MSB |

SC of Production & SB of Consumption
Social Cost (SC) of Production |
SC = |
Private cost incurred by the firm (PC)+ Externalities |
|
Social Benefit (SB) of Consumption |
SB = |
