Functions of money

Money helps people trade without finding a perfect barter partner. Its functions depend on acceptance and institutions rather than the object's appearance alone.

Medium of exchange and Unit of account

Objective: Explain medium of exchange and unit of account, distinguish their meanings, and apply them to a described case.

Medium of exchange: A medium of exchange is widely accepted in payment for goods and services. Unit of account: A unit of account provides a common measure for prices and obligations. Monetary institutions connect payment, saving, borrowing, and risk. A bank's deposits, liquid assets, and capital are different balance-sheet concepts. Policy influences financial conditions through several channels and cannot guarantee a precise response from every borrower or firm. Expectations and timing matter. An introductory model is useful for tracing a mechanism but should not be confused with a complete description of modern monetary operations. Application: A buyer pays with generally accepted currency. This most directly illustrates medium of exchange. Several products are priced in the same monetary unit. This most directly illustrates unit of account.

Step 1 — Read the observation: A buyer pays with generally accepted currency. Step 2 — Recall the relevant idea: A medium of exchange is widely accepted in payment for goods and services. Step 3 — Connect the observation to the idea: The scenario is an illustration of medium of exchange. Step 4 — Check the limit: This short scenario illustrates the concept; it does not establish every detail or exclude every other influence in a real situation.

Store of value and Liquidity

Objective: Explain store of value and liquidity, distinguish their meanings, and apply them to a described case.

Store of value: A store of value transfers purchasing power over time imperfectly when prices or risk change. Liquidity: Liquidity describes ease of converting an asset into payment without substantial loss or delay. Monetary institutions connect payment, saving, borrowing, and risk. A bank's deposits, liquid assets, and capital are different balance-sheet concepts. Policy influences financial conditions through several channels and cannot guarantee a precise response from every borrower or firm. Expectations and timing matter. An introductory model is useful for tracing a mechanism but should not be confused with a complete description of modern monetary operations. Application: Money is held for later purchases. This most directly illustrates store of value. A readily usable balance differs from a hard-to-sell asset. This most directly illustrates liquidity.

Barter and Fiat money

Objective: Explain barter and fiat money, distinguish their meanings, and apply them to a described case.

Barter: Barter exchanges goods or services directly without a monetary intermediary. Fiat money: Fiat money derives monetary acceptance from institutions and conventions rather than commodity convertibility. Monetary institutions connect payment, saving, borrowing, and risk. A bank's deposits, liquid assets, and capital are different balance-sheet concepts. Policy influences financial conditions through several channels and cannot guarantee a precise response from every borrower or firm. Expectations and timing matter. An introductory model is useful for tracing a mechanism but should not be confused with a complete description of modern monetary operations. Application: Two people swap services directly. This most directly illustrates barter. A currency is used without a promise of redemption for gold. This most directly illustrates fiat money.
