Goods Society Encourages and Discourages

Exploring goods and services that society generally wants more of (like education) or less of (like smoking), and why.

• MOE: Market Failure and Government Intervention - S4

About This Topic

This topic examines merit goods, such as education and healthcare, which society encourages through subsidies because they generate positive externalities like a healthier workforce and informed citizens. In contrast, demerit goods like cigarettes and excessive gambling face discouragement via taxes or bans due to negative externalities, including higher healthcare costs and social issues. Students identify examples and reasons, connecting individual choices to societal impacts in Singapore's context, where policies like GST vouchers promote merit goods.

Within the MOE Economics curriculum on Market Failure and Government Intervention, this builds understanding of why markets alone fail to allocate resources efficiently. Students analyze how government actions correct imbalances, preparing them for topics like indirect taxes and subsidies. Local cases, such as the Health Promotion Board's anti-smoking campaigns, make concepts relevant to everyday life.

Active learning suits this topic well. Role-plays of policy debates or sorting real Singapore goods into categories help students grapple with trade-offs and externalities hands-on. These methods foster critical thinking and empathy for diverse viewpoints, turning abstract economic theory into practical discussions.

Key Questions

1. Identify examples of goods and services that are generally considered beneficial for individuals and society (e.g., education, healthcare).
2. Identify examples of goods and services that are generally considered harmful for individuals and society (e.g., excessive gambling, sugary drinks).
3. Discuss why governments might encourage the consumption of some goods and discourage others.

Learning Objectives

• Classify specific goods and services in Singapore as either merit or demerit goods based on societal benefit or harm.
• Explain the economic rationale behind government policies that encourage the consumption of merit goods, such as education.
• Analyze the negative externalities associated with demerit goods, such as sugary drinks, and their impact on public health costs.
• Evaluate the effectiveness of government interventions, like taxes on cigarettes or subsidies for preschool education, in Singapore.

Before You Start

Introduction to Market Equilibrium

Why: Students need to understand the concept of market equilibrium to grasp why markets might fail to allocate resources efficiently for merit and demerit goods.

Basic Concepts of Supply and Demand

Why: Understanding how supply and demand interact to determine prices is fundamental to analyzing the impact of government interventions like taxes and subsidies.

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.

Watch Out for These Misconceptions

Common Misconception

Government always discourages demerit goods by banning them outright.

What to Teach Instead

Many demerit goods face taxes or regulations rather than bans to balance freedom and welfare, as seen in Singapore's tobacco duties. Active sorting activities help students distinguish tools like Pigouvian taxes from prohibitions through peer justification.

Common Misconception

Merit goods benefit only the consumer, not society.

What to Teach Instead

Positive externalities extend benefits, such as educated workers boosting productivity. Role-play debates reveal these spillovers when students defend subsidies, correcting narrow views via group negotiation.

Common Misconception

All goods society encourages are free.

What to Teach Instead

Encouragement often uses subsidies or vouchers, not full provision. Case study walks expose real costs and funding, with students actively mapping policies to dispel over-simplifications.

Active Learning Ideas

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.

30 min·Small Groups

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.

45 min·Pairs

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.

40 min·Small Groups

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.

Real-World Connections

• The Singapore government's subsidies for preschool education, such as the 'Singapore Preschool and Childcare Subsidies', aim to encourage greater participation, recognizing the positive externalities of an educated future workforce.
• The Ministry of Health's ongoing campaigns against smoking, coupled with high excise duties on tobacco products, illustrate the discouragement of a demerit good due to its significant negative externalities on public healthcare.
• Taxes on sugary drinks, introduced as part of Singapore's 'War on Diabetes' initiative, aim to reduce consumption of demerit goods by increasing their price, thereby discouraging their purchase and mitigating associated health costs.

Assessment Ideas

Quick Check

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.

Discussion Prompt

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.

Exit Ticket

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.

Frequently Asked Questions

What are examples of merit and demerit goods in Singapore?

Merit goods include education, supported by subsidies like the Edusave scheme, and healthcare via MediFund, as they yield societal benefits like skilled labour. Demerit goods encompass cigarettes, taxed heavily, and sugary drinks under new levies, due to health externalities. Students connect these to policies addressing market failures effectively.

How does this topic link to market failure?

Market failure arises when private consumption ignores externalities, underproviding merit goods or overproviding demerit goods. Governments intervene with subsidies for positives and taxes for negatives, as in Singapore's carbon tax plans. This topic illustrates inefficiency correction, building toward income inequality discussions.

How can active learning help teach goods society encourages or discourages?

Activities like debates and sorting cards engage students directly with Singapore policies, making externalities tangible. Pairs negotiate rationales, while gallery walks build evidence-based arguments. These approaches enhance retention, critical analysis, and application to real interventions over rote learning.

Why do governments intervene in consumption of certain goods?

Interventions correct externalities where individual actions affect others, like second-hand smoke or unvaccinated spread. Singapore uses incentives for merit goods, such as childcare subsidies, and disincentives for demerits via higher duties. This promotes social welfare, aligning private choices with public good.
