The Difficult Job of Cost-Benefit Analysis Cost benefit analysis refers to a study that compares the costs and benefits to society of providing a public good.

The Difficult Job of Cost-Benefit Analysis A cost-benefit analysis would be used to estimate the total costs and benefits of the project to society as a whole. It is difficult to do because of the absence of prices needed to estimate social benefits and resource costs. The value of life, the consumer’s time, and aesthetics are difficult to assess.

Tragedy of the Commons The Tragedy of the Commons is a parable that illustrates why common resources get used more than is desirable from the standpoint of society as a whole. Common resources tend to be used excessively when individuals are not charged for their usage. This is similar to a negative externality.

Summary Goods differ in whether they are excludable and whether they are rival. A good is excludable if it is possible to prevent someone from using it. A good is rival if one person’s enjoyment of the good prevents other people from enjoying the same unit of the good.

Summary Public goods are neither rival nor excludable. Because people are not charged for their use of public goods, they have an incentive to free ride when the good is provided privately. Governments provide public goods, making quantity decisions based upon cost-benefit analysis.
