Review Questions

  • Explain how monetary policy can be used to influence economic growth and unemployment in the short run.
    • Monetary policy can be used to stimulate economic growth and reduce unemployment in the short run through an expansionary approach. By lowering interest rates and increasing the money supply, the central bank can encourage more borrowing and spending by consumers and businesses. This increased demand can lead to higher production, investment, and employment, ultimately boosting economic growth and reducing unemployment. However, this approach may also lead to higher inflation, which the central bank must balance against its goals for growth and employment.
  • Describe how monetary policy can be used to address inflation in an economy.
    • When an economy is experiencing high inflation, the central bank can implement a contractionary monetary policy to slow down economic activity and control the rise in prices. This involves raising interest rates and decreasing the money supply, which makes borrowing more expensive and reduces the amount of money circulating in the economy. As a result, consumer and business spending is discouraged, leading to a slowdown in economic growth and a decrease in inflationary pressures. However, this approach may also lead to higher unemployment in the short run, as the central bank must balance its goals for price stability and employment.
  • Analyze the potential long-term consequences of using expansionary monetary policy to maintain full employment, and how this might conflict with the central bank's goal of price stability.
    • Maintaining a prolonged expansionary monetary policy to achieve full employment may lead to significant long-term consequences. Continuously low interest rates and a growing money supply can result in excessive inflation, eroding the purchasing power of consumers and undermining the central bank's primary objective of price stability. This can create a spiral of higher inflation expectations, leading to further demands for wage increases and higher prices, making it increasingly difficult for the central bank to rein in inflation without causing a recession. Additionally, the prolonged low-interest-rate environment may distort asset prices and encourage excessive risk-taking, potentially creating financial stability risks. Therefore, the central bank must carefully balance its dual mandate of price stability and maximum employment, and be willing to tighten monetary policy to control inflation, even if it means temporarily accepting higher unemployment.
