Review Questions

• How does the supply of money affect interest rates in an economy?
  • The supply of money has a direct impact on interest rates. When the central bank increases the money supply, it typically leads to lower interest rates because there is more money available for lending. This encourages individuals and businesses to borrow more, stimulating investment and consumption. Conversely, when the money supply decreases, interest rates tend to rise, which can slow down borrowing and economic activity.
• Discuss the role of a central bank in managing the supply of money and its implications for economic stability.
  • Central banks play a crucial role in managing the supply of money through monetary policy. By adjusting the money supply using tools like open market operations and reserve requirements, central banks aim to achieve economic stability. For instance, by increasing the money supply during a recession, central banks can lower interest rates and promote borrowing. However, if the money supply grows too quickly, it can lead to inflationary pressures that destabilize the economy.
• Evaluate the consequences of an excessive increase in the money supply on inflation and purchasing power.
  • An excessive increase in the money supply can lead to significant inflationary effects. As more money chases the same amount of goods and services, prices tend to rise, eroding purchasing power for consumers. This inflation can create uncertainty in the economy, affecting savings, investments, and overall consumer confidence. Long-term inflation can destabilize economic growth and reduce the effectiveness of monetary policy as people begin to expect continual price increases.
