Why does the market not supply public goods? What are the two characteristics of public goods?

A public good has two key characteristics: it is nonexcludable and nonrivalrous. ... Nonrivalrous means that when one person uses the good, it does not prevent others from using it. Markets often have a difficult time producing public goods because free riders will attempt to use the public good without paying for it.

Explanation:

“the iliad” (gr: “iliás”) is an epic poem by the ancient greek poet homer, which recounts some of the significant events of the final weeks of the trojan war and the greek siege of the city of troy (which was also known as ilion, ilios or ilium in ancient times).

the hebrew bible is the sacred text of judaism;

the koran is that of islam.

among eastern religions, the sacred scriptures of hinduis are the four vedas and the upanishads, among others.

a main characteristic in these books is that un most of them we find certain "norms" of behavior, as is the case of the bible that has it's commandments. these rules are to regulate the behavior of believers and faithful of their respective faith.

these rules tell us what is right and what is not.
