” If too many consumers decide to “free-ride,” private costs to producers will exceed private benefits, and the incentive to provide the good or service through the market will disappear. D. is … 2. Suppose government has already produced 4 units of this public good. help_outline. As a result, the social value is said to be maximized when provided for by the public. This is because HBO A. can exclude nonpaying viewers. D. marginal benefit is zero. The first attribute is excludability, or whether people can be prevented from using the good. Explain what determines the "optimal" amount of a public good and how this concept of optimality can change over time (as we elect new and different leaders). The supply curve is upward sloping, due to the law of diminishing returns. a. Is there a similar rule for public goods? In daily life, examples of private goods abound, including food, clothing, and most other goods that can be purchased in a store. A Theory of the Theory of Public Goods Randall G. Holcombe A public good, as defined by economic theory, is a good that, once produced, can be consumed by an additional consumer at no addi- tional cost. What are the two determinants of the optimal quantity of public goods? When MC = MB then there is an optimal allocation of public goods. Because of the law of diminishing returns, the marginal cost increases as the quantity of the good produced increases. The paper submits that the optimal quantity of a public good is the largest quantity demanded by any single consumer (individually or as a collective). The key intuition is that the decision to provide a public good is a function of the enjoyment that the individual gets from the total amount of the public good, net of cost. These costs and benefits will need to be translated into monetary terms for the sake of analysis. The optimal supply of public goods in a society has been a topic of discussion for many decades in the public finance literature. The cost side of the analysis would include the cost of land that must be acquired prior to construction, construction, and maintenance. Public goods can be pure or impure. Answer:To maximize social welfare, the optimal quantity of a public good to provide should be determined through the use of:private markets.the judicial system.⦠The literature tends to conclude that letting the free-market operate, without any governmental intervention, will lead to an under-supply of public goods relative to the social optimum. The provision level is asymptotically deterministic, making it possible to approximate the optimal mechanism with a mechanism that provides a fixed quantity of the good and charges fixed user fees for access.
