What is money?
Money is any item or verifiable record that is generally accepted as payment for goods and services and the repayment of debts. It functions as a universal intermediary that eliminates the need to barter.
The Core Functions
Economists define money by its ability to perform four key functions:
- Medium of Exchange: Facilitates trade by being universally accepted, preventing the requirement to trade goods directly.
- Unit of Account: Provides a common measure to price goods and services accurately.
- Store of Value: Can be saved, retrieved, and exchanged for value at a later date.
- Standard of Deferred Payment: Allows for the denomination and settlement of debts over time.
Common Types of Money
Money has evolved into distinct forms, with the most common being:
- Fiat Money: Value is established by government decree and social trust rather than a physical commodity (e.g., paper bills, coins).
- Commodity Money: Items possessing intrinsic value that are used for trade (e.g., gold, salt, cattle).
- Bank Deposits: The vast majority of money in modern economies exists digitally in bank accounts rather than as physical cash.
