Explanation:

In economics, a public good is a good that can be made available inexpensively to many consumers and at the same time it is very difficult to prevent other consumers from using or consuming this good.  

A public good is therefore defined by the two properties of non-exclusion and non-rivalry. If these criteria are met in full, then one speaks of pure public goods, otherwise of impure public goods. Public goods can cause market failures. To solve this problem, the state itself can provide the public good or create incentives for private companies to produce the good. Classic textbook examples for public goods are lighthouses or street lighting.
