Review Questions

• How do central banks use monetary policy tools to influence economic activity?
  • Central banks employ various tools like open market operations, reserve requirements, and discount rates to influence economic activity. By buying or selling government securities in open markets, they can increase or decrease the money supply. Lowering interest rates makes borrowing cheaper, encouraging spending and investment, while raising rates can help slow down an overheating economy. These actions are vital for achieving macroeconomic goals such as controlling inflation and fostering stable growth.
• Discuss how John Maynard Keynes' theories on monetary policy have shaped modern economic thought.
  • John Maynard Keynes argued that active government intervention is necessary to manage economic fluctuations. His ideas suggest that during times of economic downturns, central banks should lower interest rates and increase the money supply to stimulate demand. This perspective shifted the way policymakers approached monetary policy, moving away from classical economics that advocated for minimal intervention. Keynes' theories laid the groundwork for modern monetary frameworks that prioritize stabilizing economies through responsive monetary policies.
• Evaluate the impact of contractionary monetary policy on an economy facing high inflation.
  • Contractionary monetary policy involves raising interest rates and reducing the money supply to combat high inflation. By making borrowing more expensive, it discourages consumer spending and business investments, which can help stabilize rising prices. However, this approach also risks slowing down economic growth and increasing unemployment if implemented too aggressively. Evaluating its impact requires balancing inflation control with maintaining economic stability and employment levels, highlighting the delicate interplay between these objectives in effective monetary policymaking.
