Define the term consumer price index (CPI)?
If only cars and bikes are sold in a country and the consumer price index(CPI) has exceeded the GDP deflator what does this mean for the prices of the cars and the bike? they remain the same? Do they change differently? how does the GDP deflator supposed to move with CPI?

(a) Using a method like the CPI, compute the CPI in 2019 and 2020 and percentage change in the overall price level from 2019 to 2020 (inflation rate). Use 2019 as the base year and fix the market basket at 4 pancakes and 2 syrups.
(b) Using a method like the GDP deflator, compute the GDP deflator in 2019 and 2020 and percentage change in the overall price level from 2019 to 2020 (inflation rate). Use 2019 as the base year.
(c) Is there a difference in the inflation rate using the two methods? Explain why or why not.

- The table below shows some data I got from FRED on the CPI and PCE deflator. The PCE deflator is a price index similar to the GDP deflator but only uses the consumption ("personal consumption expenditures") part of the GDP data.

Repeat to find the annualized inflation using the PCE deflator between 2001 and 2020. The gives a higher inflation rate O PCE, and its noticeably higher (over 0.5 percentage points) PCE, but its not that different from the CPI inflation rate (difference is under 0.5 percentage points) CPI, and its noticeably higher (over 0.5 percentage points) CPI, but its not that different from the CPI inflation rate (difference is under 0.5 percentage points)arrow_forwardUse your CPI Chart to calculate the numbers 2-4. 2.
