Question

What are the four functions of money? Can something be considered money if it does not fulfill all four functions?

Short answer

The four functions of money are: a medium of exchange, a unit of account, a store of value, and a standard of deferred payment. While all these functions are closely linked and important for something to be considered money, primarily it has to be an effective medium of exchange. However, something that cannot fulfill all four functions effectively may face difficulty in being accepted as money.

Step-by-step solution

Identify the Four Functions of Money

The four functions of money are generally accepted to be: a medium of exchange, a unit of account, a store of value, and a standard of deferred payment.

Elaboration of Each Function

1. Medium of Exchange: Money is widely accepted for the exchange of goods and services. Without it, all transactions would have to be conducted by barter, which involves direct exchange of goods and services. 2. Unit of Account: Money provides a common base for measuring the value of goods and services in the economy.3. Store of Value: It allows transferred purchasing power from the present to the future. It is a way to store wealth.4. Standard of Deferred Payments: Money is used as a measure for future (deferred) payments for goods and services.

Determine if Something Can be Considered Money Without Fulfilling All Four Functions

Not necessarily; all of the four functions are intertwined. However, to be considered as money, an item primarily has to function effectively as a medium of exchange. For instance, if people accept something as a medium of exchange, it indirectly becomes a store of value and a standard of deferred payment, and naturally becomes a unit of account. Nevertheless, something that does not fulfill all four functions efficiently will likely face challenges with widespread acceptance as money.

Key concepts

Medium of Exchange

Understanding money as a medium of exchange is key to grasping its foundational role in the economy. In essence, money operates as an intermediary instrument used to facilitate the buying and selling of goods and services. Without money, these transactions would revert to bartering, where goods and services are traded directly. This presents significant challenges as it requires a double coincidence of wants—the unlikely occurrence where two parties each have what the other desires.

For example, consider the practicality it has brought to daily life: a farmer can sell his produce for money and then use that money to purchase clothes. There's no need for him to find a clothing supplier who's in need of his produce. By universally accepting money in exchange for goods and services, we can circumvent the cumbersome barter system. This seamless exchange promotes economic efficiency and growth.

Unit of Account

Money also serves as a unit of account, a standard numerical unit of measurement of the market value of goods, services, and other transactions. This function allows both consumers and businesses to make decisions about value, cost, and pricing. By having a common unit of account, it simplifies the process of comparing the value of diverse products and services.

Think of it much like a measuring tape for economic transactions. Just as a tape measure uses units like inches or centimeters, money measures the value of items in currency terms. For example, you might compare the cost of a cup of coffee to a sandwich to determine which is more valuable or worth purchasing. This simplifies decision-making and economic planning.

Store of Value

As a store of value, money must be able to maintain its value over time. It is essentially a way to preserve wealth for future use. The property of being a store of value is crucial because it provides individuals and businesses the option of saving the currency rather than spending it immediately.

To paint a clearer picture, imagine saving $100 today and being able to still use it to purchase a similar basket of goods next year. In this way, money acts as a savings mechanism. However, its effectiveness as a store of value can be influenced by issues like inflation, which reduces purchasing power over time. Thus, a stable currency, one not subject to excessive inflation or deflation, makes for the best store of value.

Standard of Deferred Payment

Finally, money functions as a standard of deferred payment, a measurement that allows for the expression of future payments for goods and services. This means that if money is borrowed today, it can be repaid with money in the future. The ease of deferring payments is essential in the world of credit and lending.

For example, when you take out a mortgage or a student loan, you're engaging in an agreement to repay the loan in the future. Money's role as a standard of deferred payment means that everyone involved knows the value of those future repayments. This enables the economy to operate more smoothly by allowing people and businesses to plan for the future and make investments with reasonable certainty of the investment's value across time.
