Step 1: Defining Externalities. Externalities are incidental economic activity effects impacting uninvolved parties. Internalization of externalities corrects market mechanisms, using tools like taxes or subsidies, to reflect external costs or benefits.
Step 2: Evaluating Options. - (A) Reciprocal or unidirectional: This is accurate. Externalities can flow mutually between parties or solely in one direction. - (B) Interdependence outside the price mechanism: This is accurate. Externalities arise when market transactions impact third parties beyond the price system. - (C) Marginal or infra-marginal: This is accurate. Externalities can be classified as marginal or infra-marginal based on their scale and effect on involved parties. - (D) Internalization requires mutual gain: This is inaccurate. The goal of internalization is to compensate the affected party (or society), not to ensure profit for all involved. The party creating the externality typically incurs costs for its internalization.
Step 3: Final Judgment. Statement (D) is incorrect because internalization does not ensure benefits for all parties involved.
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.
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.
