Money is a fundamental concept in economics, serving as the cornerstone of modern economies. It is more than just paper bills or coins—money is a system that facilitates trade, stores value, and represents wealth.
Definition of Money
- In economics, money refers to any item or verifiable record that is generally accepted as payment for goods and services and repayment of debts within a particular country or socio-economic context.
- It acts as a medium of exchange, replacing barter systems where goods were traded directly.
Core Functions of Money
- Medium of Exchange: Money is widely accepted as a method to buy goods and services, eliminating the inefficiencies of barter.
- Store of Value: It retains its value over time, allowing individuals to save for future needs.
- Unit of Account: Prices of goods and services are expressed in a uniform unit (e.g., dollars, naira, euro), making comparison easier.
- Standard of Deferred Payment: Money is used to settle debts and obligations over time.
Historical Evolution of Money
- Barter System: Prehistoric societies exchanged goods directly. However, it was inefficient due to the lack of double coincidence of wants.
- Commodity Money: Items like salt, cattle, or precious metals served as early forms of money due to intrinsic value.
- Metallic Money: Coins made from gold, silver, or copper became common due to their durability and divisibility.
- Paper Money: Introduced as receipts for metals stored in banks, paper money eventually became currency itself.
- Fiat Money: Modern currency that has value because governments declare it legal tender, not because of physical backing.
- Digital Money: Includes bank deposits, mobile transfers, and cryptocurrencies such as Bitcoin, representing the newest phase in money’s evolution.
Types of Money
