Why is the marginal .st of allowing another consumer to enjoy the benefits of a pure public good always zero even though the marginal cast of producing the good is posit,e7
Public goods are goods or services that are non-excludable and non-rivalrous in consumption. Non-excludable means that it is impossible or difficult to exclude people from using the good once it is provided, while non-rivalrous means that one person’s consumption of the good does not reduce the amount of the good available for others. This means that public goods have a collective nature and are typically provided by governments because the private sector cannot provide them efficiently due to the absence of a profit motive. Examples of public goods include national defense, public parks, and street lighting.
Pure public goods differ from pure private goods in several ways. Pure private goods are both excludable and rivalrous in consumption. Excludability means that the good can be easily withheld from those who do not pay for it, while rivalrousness means that the consumption of the good by one person reduces the amount of the good available for others. Examples of pure private goods include food, clothing, and housing.
One of the key characteristics of pure public goods is that they are subject to the free-rider problem, which arises when people can benefit from a public good without contributing to its provision. Since public goods are non-excludable, it is difficult to prevent people from benefiting from them once they are provided. This creates a situation where people have an incentive to “free ride” and not contribute to the provision of the public good, which can result in under-provision or even the complete absence of the good. This is why the provision of public goods is often left to the government, which can use its coercive powers to ensure that people contribute to the provision of the good.
The demand for a pure public good is derived from the individual demands of all the people who will benefit from the good. Since public goods are non-excludable, the total amount of the good demanded by all individuals is the vertical sum of their individual demands. This means that the demand curve for a public good is the horizontal sum of the individual demand curves, and the marginal benefit of the public good is the sum of the marginal benefits of all individuals.
Question 3 in the Checkpoint at the end of the section “The Demand for a Pure Public Good” asks: “If the government can accurately measure the marginal benefits and costs of a public good, why does it not always provide the socially optimal quantity of the good?”
One reason why the government may not always provide the socially optimal quantity of a public good is that it may face political pressures that prevent it from doing so. For example, elected officials may prioritize spending on projects that will benefit their constituents or interest groups that support them, rather than on projects that provide the greatest social benefit. Additionally, the political process may be subject to rent-seeking, where interest groups lobby the government to provide more of a public good than is socially optimal in order to benefit themselves.
Public finance tools that could be used to address this issue include cost-benefit analysis and the use of regulatory mechanisms such as taxes and subsidies. Cost-benefit analysis involves comparing the marginal social benefits and costs of a public good in order to determine whether it is socially optimal to provide it. If the benefits of the public good exceed the costs, then it is socially optimal to provide it. However, if the government is subject to political pressures that prevent it from providing the socially optimal quantity of the public good, it may be necessary to use regulatory mechanisms to internalize the externalities associated with the public good.
Question 4 in the section “Review Questions” asks: “Why does the provision of a pure public good involve a market failure?”
The provision of a pure public good involves a market failure because the private market is unable to provide the good efficiently due to the absence of a profit motive.
