Review Questions

• How do interest rates affect consumer spending and business investments?
  • Interest rates directly impact consumer spending and business investments. When interest rates are low, borrowing costs decrease, making it cheaper for consumers to take out loans for big purchases like homes or cars. For businesses, lower interest rates reduce the cost of financing new projects or expansion. Conversely, higher interest rates can lead to decreased spending and investment as borrowing becomes more expensive, leading to slower economic growth.
• Evaluate the role of central banks in managing interest rates and their implications for monetary policy.
  • Central banks play a critical role in managing interest rates as part of their monetary policy strategies. By adjusting the benchmark interest rate, they can influence economic activity; lowering rates aims to stimulate growth during downturns while raising them can help cool an overheating economy. The decisions made by central banks regarding interest rates can have widespread effects on inflation, employment levels, and overall economic stability.
• Assess the potential impact of rising interest rates on aggregate demand and overall economic performance.
  • Rising interest rates can significantly impact aggregate demand by increasing the cost of borrowing for consumers and businesses. Higher loan costs may lead to reduced consumer spending on durable goods and housing, while businesses might scale back investments due to increased financing costs. This slowdown in spending and investment can ultimately lead to lower overall economic performance, potentially resulting in slower GDP growth and higher unemployment levels.
