Review Questions

• Explain how the discount rate is used in microeconomic decision-making.
  • In microeconomics, the discount rate is used to calculate the present value of future cash flows, which is essential for evaluating the feasibility and profitability of investments and projects. A higher discount rate reduces the present value of future cash flows, making investments with longer payback periods less attractive. Businesses and individuals use the discount rate to compare alternative investment options and make informed decisions based on the time value of money and opportunity cost considerations.
• Describe the role of the discount rate in macroeconomic policy.
  • In macroeconomics, the discount rate is the interest rate set by central banks, such as the Federal Reserve, to influence the money supply and economic activity. The central bank uses the discount rate to control inflation, stimulate economic growth, and maintain financial stability. A higher discount rate makes it more expensive for banks to borrow money, which can lead to higher interest rates for consumers and businesses, reducing spending and investment. Conversely, a lower discount rate can encourage borrowing and spending, stimulating economic growth.
• Evaluate the impact of changes in the discount rate on individual and national economic decisions.
  • Changes in the discount rate can have significant implications for both individual and national economic decisions. At the individual level, a higher discount rate reduces the present value of future cash flows, making long-term investments less attractive and potentially discouraging saving and investment. Conversely, a lower discount rate can encourage individuals to borrow and invest more, as the present value of future cash flows increases. At the national level, the central bank's manipulation of the discount rate can have far-reaching effects on inflation, employment, and economic growth, as it influences the cost of borrowing, the money supply, and overall economic activity. Policymakers must carefully consider the impact of discount rate changes on both microeconomic and macroeconomic factors to achieve desired economic outcomes.
