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.
The nation's government choose which public goods and services to produce because its a command market which allow the government to make all the choices.
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
Public goods are non-excludable and non-rivalrous, meaning they are available to everyone and one person's use does not diminish another's. Common goods are rivalrous but non-excludable, meaning they can be depleted if overused but are accessible to all. The distinction impacts provision and consumption as public goods may require government intervention due to free-rider problems, while common goods may face issues of overuse without regulation.

A trait shared by at least two and perhaps more taxa and devolving on common ancestry is synapomorphy. A homologous trait is quite similar. The forelimbs of all tetrapods are devolved from common ancestry and would be traits shared by many taxa and homologous traits. Cladists use the word synapomorphy more to show closer relationships. Pliesiomorphy is the word cladists use to show more ancient relationships.
