What is Money? In this episode of Ask The Professor, Professor Milligan presents money basics, including money’s role in transactions and crypto currency.

Money is a medium of exchange that facilitates transactions of goods and services, as well as a store of value and a unit of account. It serves as a universally accepted means of payment, enabling individuals to buy goods, services, or assets, and to settle debts. Money has evolved over time and can take various forms, including physical currency, such as coins and banknotes, as well as digital or electronic forms, such as bank deposits and cryptocurrencies.

Key characteristics of money include:

Medium of Exchange: Money facilitates the exchange of goods and services by serving as a commonly accepted intermediary in transactions. It eliminates the need for barter, where goods are exchanged directly for other goods, and enables specialization and division of labor in economies.

Unit of Account: Money provides a standard unit of measurement for expressing the value of goods, services, assets, and debts. Prices are denominated in monetary units, allowing for easy comparison of the relative value of different items.

Store of Value: Money allows individuals to store wealth and purchasing power over time. It retains its value over extended periods, enabling people to save and accumulate assets for future consumption or investment.

Portability: Money is easily transportable and can be carried and exchanged conveniently, facilitating trade and commerce across geographical distances.

Divisibility: Money can be divided into smaller units or denominations, allowing for transactions of varying sizes and values. This divisibility ensures that money is flexible and adaptable to different economic activities and needs.

Durability: Money should be durable and able to withstand wear and tear over time. Physical forms of money, such as coins and banknotes, are typically made from materials that are resistant to damage and deterioration.

Acceptability: Money must be widely accepted as a means of payment by individuals, businesses, and institutions within an economy. It derives its value from the collective trust and confidence of users in its ability to facilitate transactions and preserve wealth.

Throughout history, various forms of money have been used, including commodity money (such as gold and silver), representative money (such as banknotes backed by precious metals), fiat money (issued by governments and not backed by a physical commodity), and digital or electronic money (transacted electronically through banking systems or digital currencies).

Overall, money plays a fundamental role in modern economies by facilitating economic exchange, enabling specialization and trade, promoting economic growth and development, and serving as a store of value and unit of account.
