Goods Society Encourages and DiscouragesActivities & Teaching Strategies
Active learning helps students grasp the nuanced difference between merit and demerit goods by engaging them directly with real-world examples. When students classify, debate, and simulate policies, they connect abstract economic concepts to tangible societal outcomes in Singapore’s context.
Learning Objectives
- 1Classify specific goods and services in Singapore as either merit or demerit goods based on societal benefit or harm.
- 2Explain the economic rationale behind government policies that encourage the consumption of merit goods, such as education.
- 3Analyze the negative externalities associated with demerit goods, such as sugary drinks, and their impact on public health costs.
- 4Evaluate the effectiveness of government interventions, like taxes on cigarettes or subsidies for preschool education, in Singapore.

Sorting Cards: Classify Goods Activity
Prepare cards with 20 Singapore-specific goods and services, like tuition classes, bubble tea, and public transport. In small groups, students sort them into 'encourage,' 'discourage,' or 'neutral' piles and justify with externality examples. Groups share one rationale with the class.
Prepare & details
Identify examples of goods and services that are generally considered beneficial for individuals and society (e.g., education, healthcare).
Facilitation Tip: During the Sorting Cards activity, provide 10-15 mixed examples (e.g., libraries, sugary drinks, vaccinations) and ask students to justify their placements in pairs before a whole-class reveal.
Setup: Two teams facing each other, audience seating for the rest
Materials: Debate proposition card, Research brief for each side, Judging rubric for audience, Timer
Policy Debate: Pairs Tournament
Assign pairs one merit good and one demerit good. Pairs research and debate government intervention strategies, such as subsidies versus sin taxes, using Singapore examples like MediShield Life. Vote on most convincing arguments class-wide.
Prepare & details
Identify examples of goods and services that are generally considered harmful for individuals and society (e.g., excessive gambling, sugary drinks).
Facilitation Tip: In the Policy Debate, assign roles (e.g., economist, consumer, policymaker) and require each pair to present two arguments: one supporting and one opposing intervention.
Setup: Two teams facing each other, audience seating for the rest
Materials: Debate proposition card, Research brief for each side, Judging rubric for audience, Timer
Gallery Walk: Small Groups
Display six stations with cases like sugary drink taxes or education subsidies. Small groups visit each, noting intervention types and outcomes, then create posters summarizing key learnings. Discuss as whole class.
Prepare & details
Discuss why governments might encourage the consumption of some goods and discourage others.
Facilitation Tip: For the Case Study Gallery Walk, post 4-5 real Singaporean policies (e.g., GST vouchers, tobacco duties) and have small groups rotate to identify whether each encourages or discourages a good and why.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Market Simulation: Whole Class Role-Play
Divide class into consumers, producers, and government. Simulate buying merit and demerit goods, then introduce interventions like price floors or ceilings. Track group impacts on total welfare.
Prepare & details
Identify examples of goods and services that are generally considered beneficial for individuals and society (e.g., education, healthcare).
Facilitation Tip: During the Market Simulation, assign students roles as producers, consumers, and regulators to act out how taxes, subsidies, or bans change behavior and outcomes.
Setup: Two teams facing each other, audience seating for the rest
Materials: Debate proposition card, Research brief for each side, Judging rubric for audience, Timer
Teaching This Topic
Experienced teachers approach this topic by grounding discussions in familiar Singaporean examples to reduce abstraction. Avoid presenting policies as binary choices (e.g., ban vs. no action) and instead highlight the spectrum of tools like nudges, taxes, and subsidies. Research shows students retain concepts better when they debate real dilemmas rather than memorize definitions.
What to Expect
Successful learning shows when students can categorize goods based on externalities, explain policy tools like taxes or subsidies, and articulate how individual choices affect broader welfare. Their reasoning should include specific examples and economic terminology.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Sorting Cards: Classify Goods Activity, watch for students assuming all demerit goods face bans instead of taxes or regulations.
What to Teach Instead
During Sorting Cards, circulate and ask students to explain why cigarettes are taxed in Singapore rather than banned, using the card’s policy notes to redirect their reasoning.
Common MisconceptionDuring Market Simulation: Whole Class Role-Play, watch for students claiming merit goods only benefit the individual.
What to Teach Instead
During the Market Simulation, pause the role-play to ask producers and consumers to tally how a subsidy on education affects classroom sizes or future GDP, tying individual gains to societal spillovers.
Common MisconceptionDuring Case Study Gallery Walk: Small Groups, watch for students assuming all encouraged goods are free.
What to Teach Instead
During the Gallery Walk, point students to the GST voucher case study and ask them to trace how subsidies are funded, explaining the role of taxpayers to challenge their assumption.
Assessment Ideas
After Sorting Cards: Classify Goods Activity, collect the categorization sheets and assess whether students correctly label 4 out of 5 goods and justify two with economic reasoning.
During Policy Debate: Pairs Tournament, assess student arguments by listening for the use of terms like 'externalities' and 'market failure' and whether they tie their points to Singapore’s context in at least two contributions.
After Case Study Gallery Walk: Small Groups, collect exit tickets where students name one good Singapore encourages and one it discourages, along with a specific policy and its intended outcome, to check for accuracy and clarity.
Extensions & Scaffolding
- Challenge early finishers to design a new Singaporean policy for a good not yet addressed, explaining its intended externalities and chosen tool.
- For students struggling, provide a partially completed Venn diagram comparing merit and demerit goods, with one example in each section to anchor their thinking.
- Deeper exploration: Have students research and present how one policy (e.g., sugar taxes) was implemented in another country and compare its outcomes to Singapore’s approach.
Key Vocabulary
| Merit Good | A good or service that society considers beneficial, often underconsumed if left to the free market, leading governments to encourage its consumption. |
| Demerit Good | A good or service that society considers harmful, often overconsumed if left to the free market, leading governments to discourage its consumption. |
| Positive Externality | A benefit that is shared by a third party not directly involved in the production or consumption of a good or service. |
| Negative Externality | A cost that is suffered by a third party not directly involved in the production or consumption of a good or service. |
