Review Questions

• Explain how the use of a medium of exchange overcomes the limitations of the barter system.
  • The use of a medium of exchange, such as money, allows for the separation of the act of buying and selling. In a barter system, individuals must find a direct match between their own goods or services and those of another party, which can be challenging and inefficient. With a medium of exchange, individuals can sell their goods or services for the medium and then use that medium to purchase the goods or services they desire, overcoming the 'double coincidence of wants' problem inherent in barter.
• Describe the role of liquidity in the effectiveness of a medium of exchange.
  • The liquidity of a medium of exchange is crucial to its effectiveness in facilitating transactions. A highly liquid medium of exchange, such as fiat currency, can be easily converted into other goods and services, allowing for the smooth flow of economic activity. If a medium of exchange is not widely accepted or easily convertible, it will be less effective in its role as an intermediary in transactions, hampering the efficient functioning of the economy.
• Analyze the relationship between the development of a reliable medium of exchange and the overall functioning of an economy.
  • The development of a reliable medium of exchange is considered a key function of money and is essential for the smooth functioning of an economy. A widely accepted and easily convertible medium of exchange enables the indirect trading of goods and services, overcoming the limitations of barter and facilitating the specialization of labor and the division of economic activity. The presence of a reliable medium of exchange also promotes economic stability, as it allows for the storage of value and the deferred payment of debts, supporting the development of complex financial systems and economic growth.
