Review Questions

• Explain the role of a medium of exchange in an economy and how it differs from a barter system.
  • A medium of exchange is a crucial component of a modern economy, as it allows for the indirect exchange of goods and services without the limitations of a barter system. In a barter system, individuals must find a direct match between their own goods or services and those of another party to facilitate an exchange. A medium of exchange, such as fiat currency, overcomes this challenge by providing a commonly accepted intermediary that can be used to purchase a wide range of goods and services. This enhances the efficiency and fluidity of economic transactions, as individuals no longer need to find a direct match for their goods or services.
• Describe the characteristics that make an item or commodity a suitable medium of exchange, and explain how these characteristics contribute to the effectiveness of the medium.
  • For an item or commodity to serve as an effective medium of exchange, it must possess certain characteristics. Firstly, it must be widely accepted within the economy, as the medium of exchange needs to be recognized and trusted by all participants. Secondly, it should be durable, meaning it can withstand wear and tear without losing its value. Thirdly, the medium of exchange should be portable, allowing for easy transportation and exchange. Finally, it should be divisible, enabling the exchange of goods and services in smaller denominations. These characteristics, such as widespread acceptance, durability, portability, and divisibility, contribute to the effectiveness of a medium of exchange by facilitating smooth and efficient transactions within the economy.
• Analyze the role of government and central banks in the establishment and maintenance of a stable medium of exchange, and discuss the potential consequences of instability in the medium of exchange.
  • Governments and central banks play a crucial role in the establishment and maintenance of a stable medium of exchange, such as fiat currency. Governments typically declare certain forms of currency as legal tender, which means they must be accepted as a medium of exchange within the jurisdiction. Central banks, on the other hand, are responsible for managing the money supply and ensuring the stability of the currency. This includes controlling inflation, maintaining exchange rates, and regulating the banking system. Instability in the medium of exchange, such as high inflation or currency devaluation, can have significant consequences for an economy. It can erode consumer confidence, discourage investment, and disrupt international trade and financial transactions. Ultimately, a stable and widely accepted medium of exchange is essential for the smooth functioning of an economy and the overall economic well-being of its citizens.
