1. Expansions are characterized by rising employment, increased consumer spending, and growing business investment and profits.
2. During expansions, the economy operates closer to its potential GDP, with unemployment rates declining and inflationary pressures building.
3. Expansions are typically driven by increases in aggregate demand, which can be influenced by factors such as consumer confidence, low interest rates, and government fiscal and monetary policies.
4. The length and strength of expansions can vary, with some lasting several years while others are relatively short-lived.
5. Policymakers often aim to sustain expansions and promote full employment, while also monitoring for signs of overheating and potential inflationary pressures.

Review Questions

• Explain how expansions in the business cycle are related to changes in unemployment over the short run.
  • During expansions, as economic activity and aggregate demand increase, businesses typically respond by hiring more workers to meet the growing demand. This leads to a decline in the unemployment rate over the short run, as more individuals find employment. The relationship between expansions and unemployment is inverse, with expansions driving down the unemployment rate as the economy operates closer to its potential output.
• Describe the role of aggregate demand in driving expansions and influencing short-run changes in unemployment.
  • Expansions are largely driven by increases in aggregate demand, which can be influenced by factors such as consumer confidence, low interest rates, and government policies. As aggregate demand rises, businesses respond by increasing production and hiring more workers. This in turn leads to a decline in the unemployment rate as the economy expands and operates closer to its potential GDP. The relationship between aggregate demand and short-run changes in unemployment is a key factor in understanding the dynamics of expansions within the business cycle.
• Analyze how policymakers can use fiscal and monetary policies to help sustain economic expansions and promote full employment.
  • Policymakers can employ various fiscal and monetary policies to help sustain economic expansions and promote full employment. Expansionary fiscal policies, such as tax cuts or increased government spending, can stimulate aggregate demand and support continued economic growth. Similarly, accommodative monetary policies, like lowering interest rates, can encourage business investment and consumer spending, further driving expansions. However, policymakers must carefully balance these measures to avoid overheating the economy and potential inflationary pressures. Monitoring key economic indicators and adjusting policies accordingly is crucial for maintaining a healthy, sustainable expansion and achieving full employment.
