Syllabus: Cambridge - International AS & A Level Economics
Module: 1.6 Classification of Goods and Services
Lesson: 1.6.3 Nature and Definition of Merit Goods
Jump to Section:
Introduction
This article supports the teaching of Section 1.6.3 from the Cambridge International AS & A Level Economics syllabus: The nature and definition of merit goods. This part of the syllabus falls within the broader topic of market failure, helping students understand how and why governments intervene in markets.
Merit goods are foundational to understanding public policy, economic reasoning, and real-world trade-offs. They also create opportunities to connect classroom learning with careers in public policy, health, education, and social enterprise—making this lesson both academically robust and commercially relevant.
Key Concepts
The Cambridge specification identifies the following learning outcomes in 1.6.3:
Understand and define merit goods.
Explain the reasons merit goods may be under-consumed in a free market.
Analyse information failure and its role in consumer decision-making.
Distinguish between private and social benefits.
Evaluate the case for government intervention, such as subsidies or regulation.
Teaching Tip: Encourage students to contrast merit goods with demerit goods and link back to earlier concepts like externalities and public goods (Sections 1.6.1 and 1.6.2).
Real-World Relevance
Merit goods are everywhere in public life. Key examples include:
Vaccinations – COVID-19 vaccination programmes highlighted under-consumption due to misinformation and affordability.
Education – Undervalued by individuals in the short term but crucial for long-term societal development.
Healthcare – Preventative care often under-used, leading to more expensive emergency treatment later.
Case Study: The UK’s NHS provides healthcare largely free at the point of use to counteract under-consumption. Government advertising campaigns (e.g. for flu jabs or school meals) aim to correct information gaps.
Invite students to explore how different countries treat merit goods: Why is higher education state-funded in some nations and market-based in others?
How It’s Assessed
In Cambridge A Level Economics, students should expect:
Definition and explanation questions (2–4 marks) e.g. “Define a merit good.”
Short analytical questions using diagrams (6–8 marks), such as showing under-consumption with demand/supply curves.
Essay questions (12–20 marks) asking students to evaluate government intervention in markets for merit goods.
Key command words:
Explain – often requires linking causes to outcomes
Analyse – focus on chain of reasoning and economic logic
Evaluate – weigh up arguments with evidence or contrasting viewpoints
Tip: Practice drawing and annotating diagrams that show under-consumption, external benefits, and socially optimal output.
Enterprise Skills Integration
This topic sits naturally within Decision-Making & Problem-Solving and Commercial Awareness frameworks:
Students must weigh economic evidence, evaluate government decisions, and apply strategic reasoning—skills directly relevant to the workplace.
Using simulation activities (as found in Skills Hub Futures) where students role-play as policy advisors allows them to explore how imperfect information affects market outcomes and why governments intervene.
Practical activity: Simulate a health department deciding on whether to subsidise a new vaccine. Teams assess data, costs, and potential benefits, then present their case.
Careers Links
This topic is directly relevant to several pathways:
Public Policy and Civil Service – Understanding the logic behind state intervention
Health Economics – Analysing why and how healthcare systems operate
Education Planning and Welfare Services – Budgeting and prioritising public spending
Social Entrepreneurship – Building business models that tackle under-consumed goods like healthy food or preventive care
Aligned with Gatsby Benchmark 4, this module links curriculum to real roles, helping students visualise where their economic understanding applies.
Teaching Notes
Common Pitfalls:
Confusing merit goods with public goods. Clarify that merit goods can be provided privately.
Ignoring information failure as a cause of under-consumption.
Over-simplifying government intervention without evaluating effectiveness or unintended consequences.
Extension Activities:
Compare merit good provision in the UK vs. USA.
Debate: “Should university tuition be free?” linking economic theory with real policy issues.
Use current headlines to identify modern examples of merit goods and public policy.
Cross-Curricular Ideas:
Maths – Elasticity and welfare loss diagrams
Politics – Policy decision-making and government spending
PSHE – Social value and fairness in access to services
