Final answer:
Three problems that make Consumer Price Index an imperfect measure of the cost of living are substitution bias, quality/new goods bias, and subjectivity.
Step-by-step explanation:
Three problems that make Consumer Price Index an imperfect measure of the cost of living are:
- Substitution bias: CPI uses a fixed basket of goods and doesn't account for consumers substituting cheaper goods for more expensive ones.
- Quality/new goods bias: CPI doesn't consider improvements in the quality of goods or the introduction of new goods.
- Subjectivity: CPI fails to capture individual preferences and satisfaction levels.
