Answer to Question 1

Public goods will not generally be produced by firms in the private market. For a private profit-making firm to produce a good and make a profit, it must be able to withhold that good from those who do not pay. However, a consumer acting in his own self-interest has no incentive to contribute to the production of public goods. If the social value of the goods is greater than the cost of the resources used to produce them, the production of the goods is efficient. Thus, the private market will fail to achieve the efficient outcome.

Answer to Question 2
