Macroeconomics Exam 2 Study Guide Chapter 6 Summary How the consumer price index is calculated: (example of hot dogs and hamburgers) o 1. Fix the basket. (deteroipmine which prices are more important to the consumer) 4 hot dogs and 2 hamburgers o 2. Find the prices. (find the prices of each of the goods at each point in time Year $hot togs $hamburgers 2008 $1 $2 2009 $2 $3 2010 $3 $4 o 3. Compute the basket’s cost: 2008: (1 per hot dog x 4 hot dogs) +(2perham x 2 ham) =$8 per basket 2009: (2 per hot dog x 4 hot dogs) +(3 per ham x 2 ham) =$14 2020: (3 per hot dog x 4 hot dogs) +(4 per ham x 2 ham)= $20 o 4. Choose a base year and compute the index. (2008) 2008 (8/8) x 100 = 100 2009 (14/8) x 100 = 175 2010 (20/8) x 100 = 250 o 5. Use the consumer price index to compute the inflation rate from previous year 2009 (175-100)/100 x 100 =75% 2010 (250-175) / 175 x 100 = 43% Consumer price index = price of basket of goods and services in current year / price of basket in base year x 100. Inflation rate in year 2 = CPI in year 2 – CPI in year 1 / CPI in year 1 x 100 Amount in today’s dollars = amount in year T dollars x (price level today /price level in year T) o Example on page 122 The GDP deflator differs from the CPI because it includes goods and services produced rather than goods and services consumed. As a result, imported goods affect the consumer price index but not the GDP deflator. In addition, while the CPI uses a fixed basket of goods, the GDP deflator automatically changes the group of goods and services over time as the composition of GDP changes. consumer price index (CPI) a measure of the overall cost of the goods and services bought by a typical consumer indexation the automatic correction by law or contract of a dollar amount for the effects of inflation inflation rate the percentage change in the price index from the preceding period nominal interest rate the interest rate as usually reported without a correction for the effects of inflation producer price index a measure of the cost of a basket of goods and services bought by firms real interest rate the interest rate corrected for the effects of inflation
