Review Questions

• How does an increase in the monetary supply impact interest rates and borrowing in an economy?
  • When the monetary supply increases, it generally leads to lower interest rates because there is more money available for lending. This reduction in interest rates makes borrowing cheaper for consumers and businesses, encouraging spending and investment. As a result, economic activity tends to increase as people are more likely to take out loans for homes, cars, and business expansions.
• Evaluate the role of central banks in managing the monetary supply and its effects on inflation.
  • Central banks play a critical role in managing the monetary supply through various tools such as open market operations, reserve requirements, and the discount rate. By adjusting these tools, central banks can either increase or decrease the money supply to stabilize inflation levels. When inflation is rising too quickly due to an excess money supply, central banks may tighten monetary policy by raising interest rates or selling government securities to reduce liquidity in the market.
• Assess the implications of monitoring changes in the monetary supply on economic forecasting and policy-making.
  • Monitoring changes in the monetary supply is vital for accurate economic forecasting as it provides insights into future inflation trends and overall economic conditions. Economists and policymakers analyze these changes to make informed decisions regarding fiscal and monetary policies. For example, if an increase in the monetary supply signals potential inflationary pressures, policymakers may opt to implement measures aimed at curbing spending or tightening credit to maintain economic stability.
