  • What does the Consumer Price Index (CPI) measure?
    The CPI measures the purchasing power of money over time by comparing the cost of a fixed basket of goods at different points in time.
  • How can you use the CPI to compare prices from different years?
    You can use the CPI to convert past prices into current values by applying a specific formula involving the CPI values from both years.
  • What is the formula to convert an amount from a past year to current year dollars using CPI?
    The formula is: (Amount in Year T) × (CPI in Current Year) / (CPI in Year T).
  • Why do we use a fixed basket of goods when calculating the CPI?
    A fixed basket of goods allows us to measure changes in the cost of living by keeping the quantity and types of goods constant over time.
  • If a basket of goods cost \$50 in 1990 and \$100 today, what does this say about purchasing power?
    It means that \$50 in 1990 had the same purchasing power as \$100 today, since both amounts buy the same basket of goods.

    Gen X Johnny earned \$4 per hour at his part-time job in 1975.

  • What is the 2016 equivalent of Johnny’s \$4 per hour wage from 1975?
    It is \$17.84 per hour in 2016 dollars.
  • Why is it important to adjust wages for inflation when comparing across generations?
    Adjusting for inflation allows for a fair comparison of purchasing power and economic conditions between different time periods.

  • What was the price of Johnny’s three-bedroom home in 1975?
    The home cost \$42,000 in 1975.
  • What is the main challenge in comparing wages across generations without adjusting for inflation?
    The main challenge is that the value of money changes over time, so nominal wages do not reflect true purchasing power.
  • What should students do to practice using the CPI conversion formula?
    Students should apply the formula to calculate the current value of Johnny’s annual salary and home price using the given CPI values.
