  • What is substitution bias in the context of the Consumer Price Index (CPI)?
    Substitution bias occurs when CPI assumes consumers buy the same goods each month, even if prices change and people substitute cheaper alternatives, causing CPI to overstate inflation.
  • How does the CPI handle changes in the quality of goods over time?
    CPI often fails to account for improvements in product quality, attributing all price increases to inflation rather than recognizing that some increases are due to better quality.
  • What is new product bias in the calculation of CPI?
    New product bias arises when new goods are not immediately included in the CPI basket, causing the index to miss initial high prices and later price drops, thus overstating inflation.
  • How does outlet bias affect the accuracy of the CPI?
    Outlet bias occurs when CPI uses prices from traditional stores, ignoring that consumers may buy goods at lower prices from discount stores or online, leading to an overstatement of inflation.
  • Why might the CPI overstate the actual rate of inflation?
    CPI may overstate inflation due to substitution bias, quality bias, new product bias, and outlet bias, all of which can cause the index to reflect higher prices than consumers actually pay.
  • What happens to the CPI calculation if consumers switch from buying apples to oranges due to a price increase in apples?
    CPI assumes consumers still buy the same amount of apples, so it does not account for the substitution to oranges, leading to an overstatement of inflation.
  • How does the introduction of new technology products, like cell phones, impact the CPI?
    If new technology products are not quickly included in the CPI basket, the index misses their initial high prices and later price reductions, overstating inflation.
  • What is an example of quality bias affecting the CPI?
    When cell phones improve with new features and higher quality, their prices rise, but CPI may count all of the price increase as inflation instead of recognizing the quality improvement.
  • How do changes in shopping habits, such as buying from discount stores, influence the CPI?
    If CPI calculations use higher prices from traditional stores instead of lower prices from discount outlets, it overstates the actual prices consumers pay and thus inflation.
  • Why is it important to understand the biases in CPI when studying inflation?
    Understanding these biases helps explain why CPI might not perfectly reflect the true cost of living or inflation experienced by consumers.
  • What does the CPI assume about the basket of goods over time?
    CPI assumes the basket of goods and the quantities purchased remain constant over time, even if consumer preferences change due to price changes.
  • How does the law of demand relate to substitution bias in the CPI?
    According to the law of demand, as the price of a good rises, the quantity demanded falls, leading consumers to substitute other goods, which CPI does not account for.
  • What is the effect of not including new products in the CPI basket immediately?
    It causes CPI to miss both the initial high prices and subsequent price drops of new products, leading to an overstatement of inflation.
  • How might CPI calculations differ from actual consumer spending patterns?
    CPI may use prices from traditional stores and fixed baskets, while consumers may buy from discount outlets and substitute goods, causing CPI to overstate inflation.
  • Why is the CPI still considered an important economic measure despite its biases?
    CPI remains crucial for calculating inflation and making economic decisions, even though it may not perfectly capture changes in the cost of living.
