Instructional Materials

  • News clippings on fuel subsidy and healthcare
  • Case studies on water pollution and education
  • Whiteboard & markers
  • Charts on taxes and subsidies
  • Flashcards of key terms

 

A – ANTICIPATION (10 minutes)

Starter Activity:
Ask learners the following:

“If a private company refuses to build roads because it’s not profitable, how will rural farmers transport goods to the city?”

Let students discuss in pairs and share with the class.

Purpose:
To spark curiosity about what happens when the market fails to provide essential goods or services—and introduce the term "market failure."

 

B – BUILDING KNOWLEDGE (25 minutes)

  1. Definition of Market Failure

Market failure occurs when the free market is unable to allocate resources efficiently or fairly, resulting in poor outcomes for society.

Examples:

  • A company pollutes a river while producing goods.
  • Too few people get vaccinated because they don’t see personal benefit.

 

  1. Causes of Market Failure

Cause

Explanation

Example

Externalities

Costs or benefits that affect third parties not involved in the transaction

Pollution from factories

Public Goods

Goods that are non-excludable and non-rivalrous

Street lighting, national defense

Monopoly Power

A single firm controls the market and restricts output

One telecom provider sets high call rates

Imperfect Information

Buyers/sellers lack full information to make decisions

Consumers buying fake medicines

Underprovision of Merit Goods

Society needs more of some goods than the market provides

Education, vaccines

 

  1. Government Intervention

Why? To fix market failures and promote welfare.

Tools Used by Government:

  • Taxation: To discourage harmful production (e.g., carbon tax)
  • Subsidies: To encourage production/consumption of useful goods (e.g., education subsidies)
  • Price Control: Set maximum/minimum prices (e.g., rent control)
  • Public Provision: Government provides services (e.g., public schools, hospitals)
  • Regulations: Laws to control pollution, product quality, etc.

 

  1. Case Study: Liberia’s Fuel Subsidy

During oil price hikes, the government subsidized fuel to keep transport affordable.
Result:

  • Helped the public in the short run
  • Cost the government heavily
  • Encouraged smuggling and black markets

 

  1. Advantages and Disadvantages of Government Intervention

Advantages:

  • Corrects inefficiencies
  • Protects the poor and vulnerable
  • Ensures public goods are available

Disadvantages:

  • Mismanagement and corruption possible
  • Over-regulation can discourage private investment
  • Government failure may replace market failure

 

C – CONSOLIDATION (15 minutes)

Class Activity:

Group Task: In groups of 4–5, learners analyze a real-life example (e.g., access to clean water, public transport, education) and identify:

  1. The market failure
  2. What government has done or can do
  3. The impact on society

Each group presents their analysis in 3 minutes.

 

Quick Recap:

  • Market failure happens when the market doesn't deliver optimal outcomes
  • Causes include externalities, public goods, monopolies, and information gaps
  • Government uses taxes, subsidies, and regulations to correct failure
  • Intervention has pros and cons

 

Assessment

Oral Questions:

  1. What is market failure?
  2. Name one example of public goods.
  3. Why might the government subsidize education?

Written Questions:

  1. List and explain three causes of market failure.
  2. Describe how government can use taxation to correct market failure.
  3. Identify one advantage and one disadvantage of government intervention.

 

Homework

Task: Write a short essay on how the Liberian government can improve access to clean drinking water by correcting a market failure.
