Merit good

Merit good is a science topic covered in the lgStudy science library.

Key takeaways

  • Merit good belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Merit good to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Merit good from memory before moving on to harder problems.

Reference excerpt

The economic concept of a merit good (or worthy good), originated by Richard Musgrave (1957, 1959), is a commodity or service that it is judged an individual or society should have on the basis of some concept of benefit, rather than ability and willingness to pay. The term is, perhaps, less often used in the 2020s than it was during the 1960s to 1980s, but the concept still motivates many economic actions by governments. Essentially, these are private goods that are subject to collective consumption. Examples of merit goods include in-kind transfers to people such as the provision of food stamps to assist nutrition, the delivery of healthcare services to improve quality of life and reduce morbidity, and subsidized housing and education. The opposite of a merit good is a demerit good, "a good or service whose consumption is considered unhealthy, degrading, or otherwise socially undesirable due to the perceived negative effects on the consumers themselves" (e.g., tobacco, alcoholic beverages, recreational drugs, gambling and junk food).

Definition A merit good can be defined as a good which would be under-consumed (and under-produced) by a free market economy, for two main reasons:

When consumed, a merit good creates positive externalities (an externality being a third party/spill-over effect of the consumption or production of the good/service). This means that there is a divergence between private benefit and public benefit when a merit good is consumed (i.e. the public benefit is greater than the private benefit). However, as consumers only take into account private benefits when consuming most goods, it means that they are under-consumed (and so under-produced). Individuals are short-term utility maximisers and so do not take into account the long term benefits of consuming a merit good, so they are under-consumed.

Justification In many cases, merit goods are services which proponents believe should be made available universally to everyone in a particular situation, an opinion that is similar to that of the concept of primary goods found in work by philosopher John Rawls or discussions about social inclusion. Lester Thurow claims that merit goods (and in-kind transfers) are justified based on "individual-societal preferences": just as we, as a society, permit each adult citizen an equal vote in elections, we should also entitle each person an equal right to life, and hence an equal right to life-saving medical care. On the supply side, it is sometimes suggested that there will be more endorsement in society for implicit redistribution via the provision of certain kinds of goods and services, rather than explicit redistribution through income. It is sometimes suggested that society in general may be in a better position to determine what individuals need, since individuals might act in a fashion which is deemed not to be in their own interest by others (for example, using welfare payments to buy alcohol instead of nutritious food). Sometimes, merit and demerit goods (goods which are considered to affect the consumer negatively, but not society in general) are simply considered as an extension of the idea of externalities. A merit good may be described as a good that has positive externalities associated with it. Thus, an inoculation against a contagious disease may be considered as a merit good, because others who may not catch the disease from the inoculated person also benefit. However, merit and demerit goods can be defined in a different manner without reference to externalities. Consumers can be considered to under-consume merit goods (and over-consume demerit goods) due to an information failure. This happens because most consumers do not perceive quite how good or bad the good is for them: either they do not have the right information or lack relevant information. With this definition, a merit good is defined as a good that is better for a person than the person who may consume the good realises. Other possible rationales for treating some commodities as merit (or demerit) goods include public-goods aspects of a commodity, imposing community standards (prostitution, drugs, etc.), immaturity or incapacity, and addiction. A common element of all of these is recommending for or against some goods on a basis other than consumer choice. For the case of education, it can be argued that those lacking education are incapable of making an informed choice about the benefits of education, which would warrant compulsion (Musgrave, 1959, 14). In this case, the implementation of consumer sovereignty is the motivation, rather than rejection of consumer sovereignty. Public Choice Theory suggests that good government policies are an under-supplied merit good in a democracy.

Criticism Arguments about the irrational behavior of welfare receivers are often criticised for being paternalistic, often by those who would like to reduce to a minimum economic activity by government. The principle of consumer sovereignty in welfare also suggests that monetary transfers are preferable to in-kind transfers of the same cost.

Worked examples

Example 1 — a first encounter with Merit good

Start with the simplest possible case. Write down what Merit good claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Merit good before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Merit good ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Merit good

In research
Merit good appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Merit good in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Merit good is common in secondary-school and first-year university syllabi. It links to neighbouring topics Goods, so understanding it makes those chapters shorter.
In everyday life
Look for Merit good outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
