Function and Definition of Money

Definitions of Money

According to Growther, money refers to anything that is generally accepted as a means of exchange. What’s more, it is that which at the same time acts as a measure and store of value.

John Maynard Keynes defines it as “that by delivery of which debts-contract and price-contracts are discharged, and in the shape of which a store of General Purchasing Power is held.”

Another economist named Alfred Marshal argues that money includes all things that are “current without doubt or special inquiry as a means of purchasing commodities and services and of defraying expenses.”

Functions of Money

1. Store of Value

Money is a way of transferring purchasing power from the present to the future. Money is not perishable; therefore, it can act as a store of wealth.

2. Unit of Account

Money provides the terms that make price quotation and debt recording possible. Money is a yardstick with which we measure economic transactions. With the function of money as a unit of measurement, a unitary value and a measure of value can be ascribed to goods and services.

3. Medium of Exchange

Money plays the role of the tool we use to buy goods and services. When money serves as a medium of exchange, it is used as a liquid asset and a debt settlement tool. For money to serve this purpose, it must have the following properties:

  • money should be readily acceptable;
  • money should have a known value;
  • money should be easily divisible;
  • money must have a high value relative to its weight; and
  • money should be difficult to counterfeit.


Money should be able to provide terms in which:

I. prices are quoted;

II. debts are recorded;

III. purchasing power is transferred from the present to the future; or

IV. goods are purchased.

  1. I & II only
  2.  I, III & IV only
  3.  I, II, III & IV


The correct answer is C.

Money should be able to do all of the things mentioned in points I to IV.

    Excelente para el FRM 2 Escribo esta revisión en español para los hispanohablantes, soy de Bolivia, y utilicé AnalystPrep para dudas y consultas sobre mi preparación para el FRM nivel 2 (lo tomé una sola vez y aprobé muy bien), siempre tuve un soporte claro, directo y rápido, el material sale rápido cuando hay cambios en el temario de GARP, y los ejercicios y exámenes son muy útiles para practicar.
    So helpful. I have been using the videos to prepare for the CFA Level II exam. The videos signpost the reading contents, explain the concepts and provide additional context for specific concepts. The fun light-hearted analogies are also a welcome break to some very dry content. I usually watch the videos before going into more in-depth reading and they are a good way to avoid being overwhelmed by the sheer volume of content when you look at the readings.

    A great curriculum provider. James sir explains the concept so well that rather than memorising it, you tend to intuitively understand and absorb them. Thank you ! Grateful I saw this at the right time for my CFA prep.

    I have finished my FRM1 thanks to AnalystPrep. And now using AnalystPrep for my FRM2 preparation. Professor Forjan is brilliant. He gives such good explanations and analogies. And more than anything makes learning fun. A big thank you to Analystprep and Professor Forjan. 5 stars all the way!

    Professor James' videos are excellent for understanding the underlying theories behind financial engineering / financial analysis. The AnalystPrep videos were better than any of the others that I searched through on YouTube for providing a clear explanation of some concepts, such as Portfolio theory, CAPM, and Arbitrage Pricing theory. Watching these cleared up many of the unclarities I had in my head. Highly recommended.
