Question 1 Suppose that an economy consists of only two type
Solution
Answer : a) The formula of nominal GDP is following :
Nominal GDP ( NGDP ) = Current year Price × Current year Quantities
Therefore,
NGDP in 2016 for bread = 500000 × 10 = 5000000
NGDP in 2016 for automobiles = 200 × 25000
= 5000000
For 2017,
NGDP for bread = 400000 × 20 = 8000000
NGDP for automobiles = 240 × 30000 = 7200000
b) By using 2016 as base year ,
Formula of Real GDP (RGDP) = Base year price × current year quantities.
For 2016 ,
RGDP for bread = 10 × 500000 = 5000000
RGDP for automobiles = 25000 × 200 = 5000000
For 2017,
RGDP for bread = 10 × 400000 = 4000000
RGDP for automobiles = 25000 × 240 = 6000000
c) Given, base year is 2016.
Formula of GDP deflator = (Nominal GDP / Real GDP) * 100
In 2016,
GDP deflator for bread = (5000000/5000000) * 100 =100
GDP deflator for automobiles = (5000000/5000000) * 100 = 100
In 2017,
GDP deflator for bread = (8000000/4000000) * 100 = 200
GDP deflator for automobiles = (7200000/6000000) * 100 = 120
d) Given, base year = 2016
Formula of Consumer Price Index ( CPI )
= (Base year quantities × Current year price / Base year quantities × Base year price ) * 100
In 2016,
CPI for bread = (500000*10 / 500000*10) × 100 = 100
CPI for automobiles = (200*25000 / 200*25000) × 100 = 100
In 2017,
CPI for bread = (500000*20 / 500000*10) × 100 = 200
CPI for automobiles = (200*30000 / 200*25000) × 100 =120.
