Quanriry Price Quantity Price
2015 10 $40 30 $10
2016 12 $60 50 $12

Required:
a. Using a method similar to GDP deflator, compute the percentage change in the overall price level. Use 2015 as the base year.
b. Using a method similar to the consumer price index, compute the percentage change in the overall price level. Also, use 2015 as the base year and fix the basket at 1 karaoke machine and 3 CDs.
c. Is the inflation rate in 2016 the same using the two methods? Explain why or why not.

A. 37.14

B. 34.70%

C. Not the same

Explanation:

a) Computation of the percentage change in the overall price leve

in 2015 basket price = 1*40+3*10 = $70

in 2015, basket price = 1*60+3*12 = $96

taking 2015 as base year

CPI in 2015 = 70/70 * 100 = 100

CPI in 2016 = 96/70 *100 = 137.14

%age change in price level = 137.14 - 100 = 37.14

b) Computation of the percentage change in the overall price level

GDP deflator = nominal GDP/real GDP * 100

in 2015 : (2015 as base year)

nominal GDP = 10*40+30*10

nominal GDP= $700

real GDP = 10*40+30*10

real GDP = $700

GDP deflator = 700/700 *100

GDP deflator = 100

in 2016 :

nominal GDP = 12*60+50*12

nominal GDP = $1320

real GDP = 12*40+50*10

real GDP = $980

GDP deflator = 1320/980 *100

GDP deflator = 134.70

%age change in price level based on GDP deflator = 134.70 - 100

%age change in price level based on GDP deflator = 34.70%

c) Based on the above calculation for the two methods the inflation rate in 2016 are not the same using the two methods reason been that CPI is 37.14% and GDP deflator is 34.70% .
