Goods Society Encourages and Discourages

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.

Activity 01

• Formal Debate
• 30 min · Small Groups

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.

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.

What to look for

Present students with a list of 5-7 goods and services available in Singapore (e.g., tuition classes, fast food, public libraries, lottery tickets, flu vaccinations, e-scooters). Ask them to categorize each as a merit good, demerit good, or neither, and briefly justify their choice for two items.

Activity 02

• Formal Debate
• 45 min · Pairs

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.

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.

What to look for

Facilitate a class debate: 'Should the government intervene further to discourage the consumption of [choose a specific demerit good like bubble tea] or encourage more of [choose a specific merit good like lifelong learning courses]?'. Students should use economic terms like externalities and market failure in their arguments.

Activity 03

• Gallery Walk
• 40 min · Small Groups

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.

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.

What to look for

Ask students to write down one good or service that Singapore actively encourages and one that it actively discourages. For each, they should identify one specific government policy or action and explain the intended economic outcome.

Activity 04

• Formal Debate
• 35 min · Whole Class

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.

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.

What to look for

Present students with a list of 5-7 goods and services available in Singapore (e.g., tuition classes, fast food, public libraries, lottery tickets, flu vaccinations, e-scooters). Ask them to categorize each as a merit good, demerit good, or neither, and briefly justify their choice for two items.

A few notes on teaching this unit

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.

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.

Watch Out for These Misconceptions

• During Sorting Cards: Classify Goods Activity, watch for students assuming all demerit goods face bans instead of taxes or regulations.

  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.

• During Market Simulation: Whole Class Role-Play, watch for students claiming merit goods only benefit the individual.

  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.

• During Case Study Gallery Walk: Small Groups, watch for students assuming all encouraged goods are free.

  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.
