Public Goods MCQs cover goods that are non-excludable and non-rival, along with common resources, club goods and the free rider problem. They help economics students and candidates for CSS, PMS, UGC NET and BCS. Each question gives an instant answer, so you can practise classifying goods correctly and understand why markets under-provide them.

This Economics topic classifies goods by two properties: excludability, whether people can be prevented from using a good, and rivalry, whether one person's use reduces another's. Public goods are neither excludable nor rival, private goods are both, common resources are rival but not excludable, and club goods are excludable but not rival. Questions also cover the free rider problem, the difficulty of measuring benefits in cost-benefit analysis, and why negative externalities and public goods both lead to market failure. Classification questions, such as whether a congested toll road is a private good, are favourites with examiners.

A free rider is a person who receives the benefit of a good without paying for it. Because public goods are non-excludable, people can enjoy them without contributing, so private firms find it hard to charge for them and the market tends to under-supply them.
No. A congested toll road is a private good, because the toll makes it excludable and the congestion makes it rival, as each extra car slows others. An uncongested toll road would be a club good, and an uncongested free road a public good.
