Economists use the distinction between private and public goods to determine what projects and activities should be undertaken by the government. 
In the economy, there are different types of goods among which, public goods are goods which are produced by the government or by nature for the welfare of the people without any cost. On the other hand, private goods are the ones manufactured and sold by private companies to earn a profit.
Economists use this distinction between different goods to allow the government to decide which goods are considered public goods so that the government can channel the funds in order to provide the public goods to the economy.
Hence, both public and private goods have their own importance in the economy.
