  • What is the effect of inflation on a consumer's income?
    Inflation reduces the purchasing power of a consumer's income, meaning their money buys less over time.
  • How does inflation impact financial markets?
    Inflation changes the value of interest earned, reducing its purchasing power.
  • What is interest in financial terms?
    Interest is the cost of borrowing funds or the reward for saving funds, usually expressed as a percentage.
  • How is the interest rate typically expressed?
    The interest rate is expressed as a percentage of the original amount borrowed or lent.
  • What happens to the purchasing power of interest rates when prices rise due to inflation?
    The purchasing power of interest rates decreases because the interest earned buys less than expected.
  • How do you calculate the purchasing power of savings?
    Divide the amount of savings by the price of goods to determine how many goods can be purchased.
  • If a person receives 5% interest and inflation is 2.5%, what is their real interest rate?
    Their real interest rate is approximately 2.5%, calculated by subtracting inflation from the nominal rate.
  • What is the nominal interest rate?
    The nominal interest rate is the stated rate by a bank or lender, not adjusted for inflation.
  • What is the real interest rate?
    The real interest rate adjusts the nominal rate for inflation, reflecting true purchasing power.
  • Who developed the equation to estimate real interest rate?
    Economist Fisher developed the equation to estimate real interest rate.
  • What is the Fisher equation for real interest rate?
    The Fisher equation is: real interest rate = nominal interest rate − inflation rate.
  • Why is the Fisher equation important?
    It provides a good estimate of the real interest rate, showing how inflation affects purchasing power.
  • How does inflation counteract the interest received?
    Inflation reduces the value of the interest earned, so the real gain is less than the nominal rate.
  • What should you be able to calculate using the Fisher equation?
    You should be able to calculate the approximate real interest rate in different circumstances.
  • How does inflation affect economic decisions and consumer surplus?
    Inflation impacts economic decisions by reducing purchasing power and affects consumer surplus in markets.
