Which of the following statements are correct about the contrast between pure public and pure private goods?
(A) The total provision of pure private goods is the sum of private consumption, whereas the total provision of pure public goods is equal between individuals.
(B) The consumer in general pays the same prices and consumes different quantities of the good when there is efficient provision of pure private goods.
(C) The consumer pays different prices and consumes the same quantity of the good when there is efficient provision of pure public goods.
(D) Atomistic markets ensure efficient provisioning for both pure private as well as pure public goods.
Choose the correct answer from the options given below:
Step 1: Understand the characteristics of public and private goods.
Private goods are those that are consumed by individuals, and their consumption reduces the availability for others. Public goods, on the other hand, are non-rivalrous and non-excludable, meaning consumption by one individual does not reduce the availability for others.
Step 2: Analysis of options.
- (A) The total provision of pure private goods is the sum of private consumption, whereas the total provision of pure public goods is equal between individuals: This is correct. Private goods are consumed individually, whereas public goods are consumed collectively.
- (B) The consumer in general pays the same prices and consumes different quantities of the good when there is efficient provision of pure private goods: This is correct. In private goods markets, consumers pay the same price, but they may consume different quantities based on their preferences and income.
- (C) The consumer pays different prices and consumes the same quantity of the good when there is efficient provision of pure public goods: This is correct. Public goods are typically provided at the same level for all consumers, but their funding may vary (e.g., via taxes or contributions).
- (D) Atomistic markets ensure efficient provisioning for both pure private as well as pure public goods: This is incorrect. Atomistic markets, where many small firms and consumers operate, are typically more efficient for private goods, but they do not ensure efficient provisioning of public goods due to the free rider problem.
Step 3: Conclusion.
The correct answer is (A), (B), and (C) only.
Government provides certain goods and services which cannot be provided by the market mechanism. Examples of such goods are national defence, roads, government administration etc. which are referred to as public goods.
There are two major differences between public and private goods. One, the benefits of public goods are available to all and are not only restricted to one particular consumer. For example, if a person wears a shirt, it will not be available to others. It is said that this person’s consumption stands in rival relationship to the consumption of others. However, if we consider a public park or measures to reduce air pollution, the benefits will be available to all. One person’s consumption of a good does not reduce the amount available for consumption for others and so several people can enjoy the benefits, that is, the consumption of many people is not ’rivalrous’.
Two, in case of private goods, anyone who does not pay for the goods can be excluded from enjoying its benefits. If you do not buy a ticket, you will not be allowed to watch a movie at a local cinema hall. However, in case of public goods, there is no feasible way of excluding anyone from enjoying the benefits of the good. That is why public goods are called non-excludable. Even if some users do not pay, it is difficult and sometimes impossible to collect fees for the public good. These non-paying users are known as ’free-riders’. Consumers will not voluntarily pay for what they can get for free and for which there is no exclusive title to the property being enjoyed. The link between the producer and consumer which occurs through the payment process is broken and the government must step in to provide for such goods.
A weight of $500\,$N is held on a smooth plane inclined at $30^\circ$ to the horizontal by a force $P$ acting at $30^\circ$ to the inclined plane as shown. Then the value of force $P$ is:
