Chapter 14: Money and Its Functions

Definition of Money in Economics

Money is any asset that is generally accepted as a medium of exchange for goods and services. In economics, money must fulfill specific functions to be considered as such.

• Medium of Exchange: Money is used to facilitate transactions and eliminate the need for barter.

• Unit of Account: Money provides a common measure for valuing goods and services.

• Store of Value: Money can be saved and used for future purchases.

• Standard of Deferred Payment: Money is accepted for future payments of debt.

Example: U.S. dollar bills are used to buy groceries, pay rent, and settle debts, fulfilling all four functions of money.

Liquidity and the Most Liquid Asset

Liquidity refers to how quickly and easily an asset can be converted into cash without significant loss of value.

• Most Liquid Asset: Currency (cash) is the most liquid asset because it is immediately accepted as payment.

• Other assets, such as stocks or real estate, are less liquid because they must be sold before they can be used as money.

Why Do People Hold Money?

• Transaction Motive: To make everyday purchases.

• Precautionary Motive: To have funds available for unexpected expenses.

• Speculative Motive: To take advantage of future investment opportunities.

Dollar Bills in the Modern Economy

• Dollar bills serve as fiat money, meaning their value is not backed by a physical commodity but by government decree.

• They are accepted as a medium of exchange and are legal tender for all debts, public and private.

Functions of Money

• Summarized as: Medium of Exchange, Unit of Account, Store of Value, Standard of Deferred Payment.
