Public Economics | CUET PG Economics | Notes

In economics, public goods refer to a commodity or service available to every member of society. These services are usually government-run services that are collectively funded through taxation. Public goods include law enforcement, national defense and establishing the rule of law. Also, more basic goods like access to clean air and drinking water are considered public goods. 

These are products or services that serve the common good in society and may be offered at no immediate expense by public taxation. Unlike in the case of private goods, where people have to pay separately, and the goods are scarce by nature, the public emphasizes the collective aspect of the availability of the goods. Conflicts between societies on the type of things that should be classified as a public good are usually noticed through the differences in government priorities in terms of spending.

In economics, a public good is a broader term for a good or commodity accessible to everyone, and its use by one person does not reduce its availability to others. The key characteristics of a public good are non-exclusivity and non-rivalry. Non-rivalry means that multiple individuals can consume the same good without reducing its value for others. Non-exclusivity implies that no one can be excluded from using the good; it is open to anyone for consumption.

National defence, street lighting, and law and order belong to the category of public goods, and they are equally beneficial to all. They are non-excludable and non-rivalrous; that is, no one can be denied their use, and their use does not decrease the benefit of another.

The following is a tabulated list of further examples of public goods, grouped into categories:

Security:

• The military provides national defense.
• Local law enforcement, such as police protection.
• Fire protection services.
• Neighborhood watch groups.

Education and Knowledge:

• Public schools.
• Public libraries.
• Scientific research and public reports.
• Educational community events.

Environment:

• Clean air.
• Biodiversity.
• Ozone layer protection.
• Some aspects of water resources and fish stocks can sometimes be rivalrous.

Infrastructure:

• Roads, bridges, and dams.
• Street lighting.
• Sidewalks and crosswalks.
• Sewage systems.

Public Health:

• Disease control programs.
• Vaccination campaigns.
• Public information on health and hygiene.
• Hospitals and medical facilities (in some cases).

Information and Culture:

• Public television and radio.
• Free and open-source software.
• Official statistics and data.
• Public fireworks and community celebrations.

An Overview of Public Good Examples:

Mechanism of Public Goods:

Public‍‌‍‍‌‍‌‍‍‌ goods serve as the basis for the overall welfare of a society, thus they constitute the source of common responsibility and collective development which should be a source of admiration and acknowledgement for both learners and policymakers.

How Public Goods Are Produced and Funded:

• Government Provision: In the majority of nations, the government delivers public goods by means of ‍‌‍‍‌‍‌‍‍‌taxes.
• Non-Profit Organisations: Sometimes NGOs and civil groups step in to provide services such as free education or clean water.
• Public-Private Partnerships (PPPs): Governments often work with private firms to build infrastructure such as roads and bridges.

Key Characteristics of Public Goods:

The Free-Rider Problem:

As‍‌‍‍‌‍‌‍‍‌ public goods are available at no charge to everyone, most people would not want to pay for them. This phenomenon is called the free-rider problem. As examples:

• People enjoy clean air but may not contribute to reducing pollution.
• Citizens benefit from national security without directly paying for it.

Role of Taxation and Government:

• Taxes‍‌‍‍‌‍‌‍‍‌ pay for things that everybody uses, such as health care, roads, police, and more.
• The government ensures that everyone gets their share and tries to prevent both overuse and underfunding.
• In India, these are some of the examples where you can see public goods turning into realities through schemes like Mid-Day Meal, Swachh Bharat Abhiyan, and free vaccination ‍‌‍‍‌‍‌‍‍‌drives.

Characteristics of Public Goods:

Public good in economics has a plural and technical meaning not limited to the public’s well-being; unlike public goods in political science, they are freely available to the consumer. They are not explicitly meant for specific groups of individuals. When one person uses it, it does not restrict others from consuming the goods. The two main qualities are

Non-Rivalrous:

• When you use it, you do not limit its availability to others. Even though our tastes differ, we reap the same benefits. Consider the example of a street light. When you drive on the highway, you and others benefit from it.
• It may differ slightly for different highways. When the route is congested, the benefits accessible to others are reduced. Meanwhile, toll roads require payment to use. However, when you utilize a toll road, you cannot prevent others from using it.

Non-Excludable:

• It is available for everybody, and everyone has access to it. A particular individual does not have control over who uses these goods.

Capitalism and the Public Goods:

Capitalism is an economic system where an individual is free of economic activity, and the government protects other aspects of the state. Presently, most economies prefer the capitalist system. In a capitalist ecosystem, most goods available for an individual for consumption are private, but it also provides many public goods.

• Various industries, businesses, and companies work to satisfy customers’ demands and produce private goods, but complementary components provide public goods to the country’s citizens.
• Private businesses will generate revenue through taxes, and the government will use those taxes to provide public goods to its citizens.
• In this system, where public and private goods co-exist, private players generate goods for their customers. In turn, the State guarantees them market protection, justice, and order for the stable and safe functioning of the system.

The Relation Between Public Goods and Market Failure:

• Market failure is a situation in a free market where there is an insufficient distribution of goods and services.
• Market failures generally include externalities, monopolies, information asymmetries, and factor immobility. In simple words, market failure is a public goods problem.
• The private sector is unwilling to supply entirely public goods because it is unprofitable. When a firm supplies goods and services, few people use them without paying, and they can’t be stopped. This issue of free riders eventually leads to a shortage of products.
• The expenses of delivering goods outweigh the profits. The private sector has little motivation to supply such items.
• As a result, the market will be unable to supply sufficient goods or services. The government must step in because the private sector is unwilling to offer commodities. Even though they are not for-profit, they provide more significant social benefits.
