The history of money is the development over time of systems for the exchange of goods and services. Money is a means of fulfilling these functions indirectly and in general rather than directly, as with barter.

Monetary economics is the branch of economics that studies the nature, role, and impact of money and monetary institutions. It provides a framework for analyzing money and its core functions—as a medium of exchange, a store of value, and a unit of account—and examines how money can achieve widespread acceptance, including through its role as a public good.
