Review Questions

• How does a medium of exchange improve economic efficiency compared to a barter system?
  • A medium of exchange improves economic efficiency by eliminating the need for double coincidence of wants that is essential in a barter system. In bartering, both parties must have what the other desires, which can limit trade opportunities. By using a medium of exchange, individuals can sell their goods or services for money and then use that money to purchase what they need from others. This creates more flexible and extensive trade networks, enhancing overall market efficiency.
• Discuss how the characteristics of a good medium of exchange influence its effectiveness in an economy.
  • The effectiveness of a good medium of exchange in an economy is largely influenced by its characteristics such as acceptability, portability, durability, divisibility, and fungibility. Acceptability ensures that it is widely recognized as payment for goods and services. Portability allows it to be easily carried for transactions. Durability means it should withstand physical wear over time. Divisibility enables it to be broken down into smaller units for varied transaction sizes, while fungibility guarantees that individual units are interchangeable. Together, these characteristics enhance confidence and utility in the use of money as a medium of exchange.
• Evaluate the impact of transitioning from commodity money to fiat currency on the role of medium of exchange in modern economies.
  • The transition from commodity money to fiat currency has significantly transformed the role of medium of exchange in modern economies by enhancing flexibility and control over monetary policy. Commodity money was limited by the availability and intrinsic value of materials like gold or silver, which could restrict economic growth. In contrast, fiat currency derives value from government backing and can be adjusted according to economic needs through monetary policy tools. This allows for better management of inflation and deflation, making fiat currencies more effective as mediums of exchange in facilitating transactions and stabilizing economies.
