  1. Chapter 11 Measuring the Cost of Living

  2. Outline • Construction of CPI • Calculation of CPI and the Inflation Rate • Problems in measuring CPI • GDP Deflator versus CPI • Correcting economic variables for the effects of inflation • Indexation • Real and Nominal interest rates

  3. CPI • The Consumer Price Index (CPI) is a measure of the overall cost of the goods and services bought by a typical consumer. • CPI measures changes in the cost of living over time. • CPI estimates by how much incomes must rise to maintain a constant standard of living. • CPI reflects the purchasing power of the currency • It reports the movement of prices with an index number.

  4. Calculating CPI: Various Steps • Fix the Basket: Identify the basket of goods consumed by a typical consumer • Find the Prices: Find the prices of each of the goods and services in the basket for each point in time • Compute the Basket’s Cost: Calculate the cost of the basket of goods and services at different times • Choose a base year and compute the index: Designate one year as the base year. CPI= (price of basket in current year/ price of basket in base year)x100

  5. Calculating CPI: Various Steps 5. Calculate the Inflation Rate: Use the CPI to calculate the inflation rate. • Inflation rate is the percentage change in the price index from the preceding period.

  8. Problems in Measuring The Cost of Living • The CPI is not a perfect measure of the “cost of living.” • Three reasons/problems: • Substitution Bias: Consumers substitute toward goods that have become relatively less expensive • Introduction of new goods: With greater variety consumers need fewer dollars to maintain any given standard of living • Unmeasured quality change: Quality impacts on the value of the currency

  9. The Consumer Price Index versus the GDP Deflator • The CPI: • includes only consumption goods • includes the cost of imports • is a fixed bundle of goods • The GDP Price Deflator: • includes all final goods and services • excludes imports • uses a current bundle of goods

  10. Correcting Economic Variables for the Effects of Inflation • To convert (inflate) past wages and prices into current terms: Current Year Dollars = Past Year Nominal Value X [(Price index in current year) ÷ (Price index in past year)]

  11. Correcting Economic Variables for the Effects of Inflation • To convert (deflate) current wages and prices into past year terms: Value in Past Year Dollars = Current Year Value X [(Price index in past year) ÷ (Price index in current year)]

  12. Indexation • Indexation is the automatic correction of a dollar amount for the effects of inflation by law or contract. E.g., COLA • Real interest rate= Nominal interest rate- Inflation rate
