If a commodity is provided free to the public by the Government, then

Your answer:  ·  Correct: C
Explanation

The opportunity cost of an activity is the value of benefits that have to be given up by using the resources for the chosen activity rather than for something else.[1] When the government provides a commodity free to the public, the opportunity cost does not disappear—it simply shifts to those who fund the government. Governments raise money through taxes and other ways to meet expenses on the services rendered by it.[2] When the government bears part of the cost of providing goods or services, it has to bear some of the cost.[3] Therefore, while consumers receive the commodity free and pay no direct price, the tax-paying public ultimately bears the opportunity cost through the taxes they pay. The resources used to provide the free commodity could have been used for alternative government expenditures, and this cost is borne by taxpayers, not by the direct consumers of the product.

This is a classic 'First Principles' question derived directly from the definition of Opportunity Cost in NCERT Class XII Microeconomics. It tests conceptual clarity over rote memorization—specifically, the economic axiom that 'there is no such thing as a free lunch' (TINSTAAFL).

How this question is built

This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.

Statement 1
When a commodity is provided free to the public by the government, is the opportunity cost zero?

"The opportunity cost of an activity is the value of benefits that have to be given up by using the resources for the chosen activity rather than for something else. With regard to government expenditure in our context, assessing the opportunity cost would mean assessing what the funds spent on, for example, the construction of a fishing harbour, could have been used for instead - maybe a school or improved health services - and the value of these foregone benefits."
Why this source?
  • Defines opportunity cost as the value of benefits forgone when resources are used for one activity rather than another — implying a non-zero cost when government resources are used.
  • Applies that definition directly to government expenditure, showing funds used for one public good mean foregone benefits from alternative uses (e.g., schools or health services).

"The "value to the industry" equals the financial opportunity cost, i.e., how much would it have cost to borrow the same capital? The annual value of the subsidy is calculated as the estimated interest cost at market rates for a loan equalling the state equity of the company."
Why this source?
  • Shows that even where government cost reporting may be minimal, the 'value to the industry' is taken as the financial opportunity cost — i.e., an alternative cost exists and can be measured.
  • Gives a concrete example (subsidy valued as interest cost) of how opportunity cost is calculated, contradicting the idea that it is zero when the government provides something free.

"However, generally, unless we have very clear indications of its value, the Guide recommends ignoring the opportunity cost since its calculation is likely to be arbitrary at the best. | BOX 4 **Opportunity costs** The total cost to society of an economic activity can be referred to as its social cost."
Why this source?
  • Notes that while opportunity cost can be difficult to quantify and sometimes is ignored in practice, that is a methodological choice — not evidence that opportunity cost equals zero.
  • Frames opportunity cost as a component of social cost, reinforcing that resources used by government have alternative uses and associated costs.

“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 nonpaying 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.”
Why relevant

Explains public goods are non-excludable and government must provide them because private provision fails (free-rider problem).

How to extend

A student could note that provision requires resources (production/administration) and therefore infer alternatives forgone—so investigate what resources the government uses and their other uses.

“• 1. Public goods, as distinct from private goods, are collectively consumed. Two important features of public goods are – they are non-rivalrous in that one person can increase her satisfaction from the good without reducing that obtained by others and they are non-excludable, and there is no feasible way of excluding anyone from enjoying the benefits of the good. These make it difficult to collect fees for their use and private enterprise will in general not provide these goods. Hence, they must be provided by the government.• 2. The three functions of allocation, redistribution and stabilisation operate through the expenditure and receipts of the government.• 3.”
Why relevant

Defines public goods as non-rivalrous and non-excludable and states private enterprise will not provide these goods, so government provision is necessary.

How to extend

Use the definition to identify examples (roads, dams) and check the budgetary cost of supplying them to see what public funds could otherwise finance.

“To get such services we have to pay money to these individuals and companies. The purpose of the public sector is not just to earn profits. Governments raise money through taxes and other ways to meet expenses on the services rendered by it. Modern day governments spend on a whole range of activities. What are these activities? Why do governments spend on such activities? Let's find out. There are several things needed by the society as a whole but which the private sector will not provide at a reasonable cost. Why? Some of these need spending large sums of money, which is beyond the capacity”
Why relevant

Says governments raise money through taxes to meet expenses on services they provide.

How to extend

Combine with basic fiscal facts (taxes are limited) to reason that spending on a 'free' commodity uses tax revenue that could be spent elsewhere, implying a non-zero opportunity cost.

“of the private sector. Also, collecting money from thousands of people who use these facilities is not easy. Even if they do provide these things they would charge a high rate for their use. Examples are construction of roads, bridges, railways, harbours, generating electricity, providing irrigation through dams etc. Thus, governments have to undertake such heavy spending and ensure that these facilities are available for everyone. There are some activities, which the government has to support. The private sector may not continue their production or business unless government encourages it. For example, selling electricity at the cost of generation may push up the costs of production of goods in many industries.”
Why relevant

Gives examples (roads, bridges, electricity, irrigation) of services where government undertakes heavy spending because private sector won't at reasonable cost.

How to extend

A student can pick one example, estimate resource inputs (labour, materials) or budget outlays and compare alternative uses to judge the opportunity cost of providing it free.

“Can you think of any commodity on which price ceiling is imposed in India? What may be the consequence of price-ceiling?• 21.A shift in demand curve has a larger effect on price and smaller effect on quantity when the number of firms is fixed compared to the situation when free entry and exit is permitted. Explain.• 22.Suppose the demand and supply curve of commodity X in a perfectly competitive market are given by: • q D = 700 – p = 0 for 0 ≤ p < 15 Assume that the market consists of identical firms. Identify the reason behind the market supply of commodity X being zero at any price less than Rs 15.”
Why relevant

Discusses price ceilings and market supply behavior, illustrating that market prices (or absence thereof) affect supply decisions.

How to extend

Extend by examining how making a commodity free (price = 0) would change private supply and require government to fill the gap using resources—suggesting a cost in alternatives forgone.
