Review Questions

• How does an increase in the quantity of money supplied affect interest rates and economic activity?
  • When the quantity of money supplied increases, it generally leads to lower interest rates because there is more money available for lending. This reduction in interest rates makes borrowing less expensive for consumers and businesses, which can encourage spending and investment. As a result, increased economic activity often follows since more funds are circulating in the economy, stimulating growth.
• Evaluate the role of central banks in managing the quantity of money supplied and its impact on inflation.
  • Central banks play a critical role in managing the quantity of money supplied through various monetary policy tools such as open market operations, adjusting interest rates, and setting reserve requirements for banks. By controlling the money supply, central banks aim to maintain price stability and prevent inflation from rising too quickly. When they increase the supply without a corresponding growth in goods and services, it can lead to inflationary pressures as more money chases the same amount of products.
• Analyze how changes in the quantity of money supplied can impact long-term economic growth and stability.
  • Changes in the quantity of money supplied can have significant implications for long-term economic growth and stability. For instance, if a central bank maintains a stable and predictable growth rate of money supply that matches the economy's output growth, it can foster a stable environment conducive to investment and productivity gains. Conversely, erratic changes or excessive increases in the money supply may lead to volatility in inflation and interest rates, undermining investor confidence and potentially stunting economic growth over time.
