Market Failure (Copy)

Definition of Market Failure (2.10.1)

• Market failure occurs when the free market, left to itself, fails to allocate resources efficiently, leading to a loss of economic and social welfare.
• In other words, the market does not produce the right quantity of goods and services at the right price to maximize overall benefits.
• Instead of achieving equilibrium that benefits society, market forces cause either overproduction (too many resources allocated) or underproduction (too few resources allocated).

Key Terms

• Public good: Goods that are non-excludable and non-rivalrous, e.g., street lighting, defense.
• Merit good: Goods that provide greater social benefits than private benefits, often under-consumed, e.g., education, healthcare.
• Demerit good: Goods that create social costs greater than private costs, often over-consumed, e.g., cigarettes, alcohol.
• Private benefits: Gains enjoyed by individuals or firms from consumption/production.
• External benefits: Benefits enjoyed by third parties not directly involved in a transaction.
• Social benefits: Private benefits + external benefits.
• Private costs: Costs borne by individuals or firms directly involved.
• External costs: Costs borne by third parties not involved in a transaction.
• Social costs: Private costs + external costs.

Causes of Market Failure (2.10.2)

1. Public Goods
   • Public goods (e.g., national defense, streetlights) are non-excludable (people cannot be stopped from using them) and non-rivalrous (use by one does not reduce availability for others).
   • Free market fails because firms cannot charge individuals; leads to the free rider problem.
2. Merit Goods
   • Examples: Education, healthcare, vaccinations.
   • People undervalue long-term benefits, leading to under-consumption.
   • Without government intervention, society loses potential benefits.
3. Demerit Goods
   • Examples: Alcohol, tobacco, drugs.
   • Consumers over-consume due to short-term pleasure and lack of awareness of negative externalities.
   • Leads to over-allocation of resources.
4. Externalities
   • Negative externalities (external costs): Pollution from factories, traffic congestion, noise.
   • Positive externalities (external benefits): Education leading to more skilled workforce, vaccination protecting communities.
   • Market fails because these costs/benefits are not reflected in the price mechanism.
5. Monopoly Power
   • When one firm dominates the market, it may abuse power:
     • Restrict supply to raise prices.
     • Reduce consumer choice.
     • Exploit workers with low wages.
6. Factor Immobility
   • Labour or capital may not move easily between industries or regions.
   • Example: Workers trained in coal mining may struggle to find jobs in technology industries.
   • Leads to structural unemployment.

Consequences of Market Failure (2.10.3)

1. Misallocation of Resources
   • Too many resources allocated to demerit goods.
   • Too few resources allocated to merit goods.
2. Over-consumption of Demerit Goods
   • Health issues (smoking-related diseases).
   • Increased healthcare costs for society.
   • Reduced productivity due to illness.
3. Under-consumption of Merit Goods
   • Less education = lower skilled workforce.
   • Lower productivity and slower economic growth.
4. External Costs (Negative Externalities)
   • Example: Air pollution from factories affects health and environment.
   • Costs not included in product price → overproduction.
5. External Benefits (Positive Externalities)
   • Example: Vaccination programs reduce disease spread.
   • Without government support, under-provided by free market.
6. Monopoly Power Consequences
   • Higher prices and reduced consumer welfare.
   • Exploitation of both consumers and workers.
7. Factor Immobility Consequences
   • Widespread unemployment in declining industries.
   • Wasted resources and reduced national output.

           Social optimum <----> Market equilibrium

Market equilibrium shows higher consumption than social optimum because external costs ignored.

2. Under-Consumption of Merit Goods

Price

Socially optimal demand > Private demand.
Hence under-consumption in free market.

3. Positive Externalities (e.g., education)

Price

Equilibrium < Social optimum → under-provision.

Monopoly restricts output → higher prices, lower consumer welfare.
