Public goods can best be described as services provided by the government to benefit all citizens.
Common goods are resources that are available to everyone in a community, such as clean air or water. Public goods, on the other hand, are goods or services provided by the government for the benefit of all citizens, like public parks or national defense. Common goods can be depleted if overused, while public goods are non-excludable and non-rivalrous, meaning they are available to all and using them does not diminish their availability to others. Common goods and public goods impact society differently by influencing resource management, economic development, and social welfare.

Its failure to assign the costs of public goods to all consumers.
What to produce?There are two aspects of this problem--- firstly, which goods should be produced, and secondly, what should be the quantities of the goods that are to be produced. The first problem relates to the goods which are to be produced. In other words, what goods should be produced? An economy wants many things but all these cannot be produced with the available resources.Therefore, an economy has to choose what goods should be produced and what goods should not be. In other words, whether consumer goods should be produced or producer goods or whether general goods should be produced or capital goods or whether civil goods should be produced or defense goods. The second problem is what should be the quantities of the goods that are to be produced.Production of goods depends upon the use of resources. Hence, this problem is the problem of allocation of resources. If we allocate more resources for the production of one commodity, the re­sources for the production of other commodities would be less.

Collective provision of goods and services are possible only in the case of Public Goods. Public goods are also known as Collective goods.non excludabilitynon - rival consumptionare the characteristics of the Public Goods. These are a very special class of goods which cannot practically be withheld from one individual consumer without withholding them from all (the "non-excludability criterion") and for which the marginal cost of an additional person consuming them, once they have been produced, is zero (the "non-rivalrous consumption" criterion). The classic example of a nearly pure public good is national defense
