‘The classification of merit and demerit goods depends upon a value judgement.’
Introduction
Merit and demerit goods are central to understanding market failure. Their classification is not purely objective but depends on value judgements, raising important debates in economics.
Understanding Value Judgements in Economics
Economics often distinguishes between positive statements (objective, testable claims) and normative statements (opinions or judgements). The classification of goods as merit or demerit falls into the normative category.
Value judgement: An assessment based on personal beliefs, societal norms, or ethical views, rather than purely objective or scientific criteria.
This means economists, policymakers, and individuals may disagree on whether a good should be encouraged (merit) or discouraged (demerit).
Merit Goods and Value Judgements
Merit goods are those considered beneficial for individuals and society, but often under-consumed in a free market. Examples include healthcare, education, and vaccinations.
Merit good: A good that is judged to provide greater social benefits than individuals realise, leading to under-consumption if left to the free market.
The value judgement arises because deciding what is "beneficial" involves subjective reasoning. For instance, governments may promote higher education not only for individual earnings but also for wider societal productivity. Some may argue, however, that individuals should freely decide without government influence.
Characteristics of merit goods influenced by judgement
They often generate positive externalities (e.g. education increases productivity and civic participation).
They may involve imperfect information, where consumers underestimate benefits.
Policymakers must decide whether these goods require subsidies or state provision.
Demerit Goods and Value Judgements
Demerit goods are seen as harmful to individuals and society, often over-consumed in a free market. Examples include tobacco, alcohol, and junk food.
Demerit good: A good that is judged to impose greater social costs than individuals perceive, leading to over-consumption in a free market.
Again, the classification depends on judgement. For example, some may see moderate alcohol consumption as harmless or even socially beneficial, while others classify it as demerit due to health risks.
Characteristics of demerit goods shaped by judgement
They generate negative externalities (e.g. smoking causes healthcare costs).
They often involve imperfect information, with consumers underestimating long-term harm.
Governments frequently impose taxes, regulation, or bans to discourage use.
Why Classification Depends on Judgement
Determining merit or demerit status is not purely scientific because:
Cultural values: One society may consider gambling a leisure activity, while another treats it as harmful.
Ethical perspectives: Views differ on whether the state should intervene in personal choices.
Political ideology: A socialist government may classify more goods as merit, while a liberal government may prefer individual responsibility.
Scientific uncertainty: New research may alter views on health risks or benefits, influencing classification.
The Role of Governments and Policy Implications
Because classification depends on judgement, government decisions reflect societal preferences at a given time.
Implications of classifying a good as merit:
Subsidies or free provision (e.g. NHS healthcare in the UK).
Information campaigns to raise awareness of benefits.
Regulation to ensure minimum consumption levels (e.g. compulsory education until age 18).
Implications of classifying a good as demerit:
Higher indirect taxes (e.g. duties on alcohol, cigarettes).
Advertising restrictions (e.g. tobacco advertising bans).
Bans or strict regulations (e.g. hard drug prohibition).
These policies rely on the government’s value judgement about what benefits or harms society.
Debates and Controversies
The value-laden nature of classification creates controversy:
Freedom of choice vs paternalism
Critics argue that individuals, not governments, should decide what to consume.
Supporters of intervention claim imperfect information prevents rational decision-making, justifying state involvement.
Shifts over time
What counts as merit or demerit may change with evolving social norms. For example:
Smoking: Once widely accepted, now heavily restricted.
Education: Once optional beyond basic literacy, now extended and state-supported.
Global variations
In some cultures, alcohol is a normal good, while in others it is seen as entirely demerit.
Healthcare in some countries is seen as a private responsibility, while in others it is treated as a merit good provided universally.
Key Points for Students
Merit and demerit goods are not defined purely by objective criteria but by value judgements.
These judgements shape whether goods are subsidised or taxed.
Disagreements reflect cultural, ethical, political, and informational factors.
The classification of goods is dynamic and contested, not fixed or universal.
FAQ
Economists disagree because classification depends on value judgements rather than objective evidence. What one economist considers beneficial may be viewed as unnecessary by another.
Disagreement often arises from different ethical frameworks, political ideologies, or cultural influences. For example, healthcare is universally seen as a merit good in some countries, while in others it is treated as an individual responsibility.
Yes, social norms and scientific knowledge evolve, which can shift how goods are classified.
Smoking was once widely accepted but is now strongly regulated as a demerit good.
Education beyond basic literacy was once optional but is now widely considered a merit good essential for economic development.
These changes highlight the dynamic nature of value judgements in economics.
Cultural values strongly shape perceptions of goods.
In some cultures, alcohol is a normal social good; in others, it is strictly prohibited and classified as demerit.
Gambling may be a leisure activity in one society but seen as harmful and morally unacceptable in another.
This shows how classification is not universal but context-specific.
Imperfect information makes it harder for individuals to judge the true costs or benefits of consumption. Governments may step in with their own value judgements.
For example, consumers might underestimate long-term health benefits of vaccinations or the risks of fast food. Policymakers then classify these goods as merit or demerit to adjust for perceived under-consumption or over-consumption.
Externalities often underpin the classification of merit and demerit goods.
Merit goods typically generate positive externalities, such as education improving productivity and civic engagement.
Demerit goods often create negative externalities, like smoking leading to higher public healthcare costs.
The decision to highlight these externalities in policy reflects a value judgement on what outcomes society prioritises.
