3. Monetarists argue that the central bank should focus on controlling the money supply growth rate to achieve stable prices and full employment, rather than using discretionary fiscal policy.
4. Monetarists emphasize the role of expectations in the economy, suggesting that if the central bank can establish a credible commitment to low inflation, it can influence expectations and reduce the costs of disinflation.

Review Questions

• Explain how monetarist theory differs from Keynesian economics in its approach to understanding economic issues.
  • Monetarist theory differs from Keynesian economics in its emphasis on the role of the money supply as the primary driver of economic activity. While Keynesian economics focuses on the use of fiscal policy, such as government spending and taxation, to stabilize the economy, monetarists believe that monetary policy, specifically the control of the money supply, is the most effective tool for achieving economic stability and growth. Monetarists argue that changes in the money supply have a direct and predictable impact on the price level and real economic output in the long run, whereas Keynesians see a more complex relationship between fiscal policy, aggregate demand, and economic outcomes.
• Analyze how the monetarist view of the role of expectations in the economy differs from the Keynesian perspective.
  • Monetarists place a greater emphasis on the role of expectations in the economy compared to Keynesians. Monetarists believe that if the central bank can establish a credible commitment to low inflation, it can influence expectations and reduce the costs of disinflation. This is because people will adjust their behavior, such as wage and price setting, in anticipation of the central bank's actions, leading to a more efficient adjustment process. In contrast, Keynesians tend to focus more on the immediate impact of policy changes on aggregate demand, with less emphasis on the role of expectations in shaping economic outcomes. Keynesians may argue that policy changes can have different effects depending on how they are perceived by the public, but they generally do not place as much weight on the importance of credible policy commitments in influencing expectations.
• Evaluate the extent to which monetarist theory has influenced the policy decisions of central banks around the world.
  • Monetarist theory has had a significant influence on the policy decisions of central banks around the world, particularly since the 1970s and 1980s. Many central banks have adopted a greater emphasis on monetary policy as the primary tool for macroeconomic stabilization, focusing on controlling the money supply growth rate to achieve stable prices and full employment. This shift towards a monetarist-inspired approach has been reflected in the adoption of inflation targeting frameworks, the increased independence of central banks, and a greater emphasis on price stability as the primary objective of monetary policy. However, the extent to which monetarist theory has influenced central bank policies varies across countries and over time, as policymakers have also had to grapple with the limitations of monetary policy and the complexities of modern economic systems. Nonetheless, the monetarist perspective has left an indelible mark on the way central banks approach the challenge of managing the macroeconomy.
