Consider an economy that produces and consumes coffee, bread and auto- mobiles. In the following table, we have data for two different years. The first 2 questions refer to this table.

1) Using the year 2017 as the base year, compute the following statistics for each year: nominal GDP, real GDP, the GDP deflator (a Paasche price index) and the CPI (a Laspeyres price index. For the CPI, assume that the representative basket of goods is exactly the one produced in the year 2017
2) How high was the inflation rate between 2017 and 2018, based on the GDP deflator, and based on the CPI?
For the year 2017,
Nominal GDP = 30000*1000 + 1.5*400000 + 2*100000 = 30800000
Real GDP = 30000*1000 + 1.5*400000 + 2*100000 = 30800000
Implicit price deflator = (Nominal GDP/ real GDP)*100 = 100
CPI = 30000*1000 + 1.5*400000 + 2*100000 = 30800000
For the year 2018,
Nominal GDP = 30500*1100 + 1.6*400000 + 2.2*105000 = 34421000
Real GDP = 30000*1100 + 1.5*400000 + 2*105000 = 33757500
Implicit price deflator = (Nominal GDP/ real GDP)*100 = (34421000/33757500)*100 = 101.96
CPI = 30500*1000 + 1.6*400000 + 2.2*100000 = 31360000
Inflation based on deflator = (101.96-100)/100 = 1.96%
Inflation based on CPI = (31360000-30800000)/30800000 = 0.018181 = 1.82%
Increase in price (using deflator) = (152-100)/100 = 52%
Value of basket in 2000 = 50000*100 + 10*500000 = $10000000
Value of basket in 2010 =60000*100 + 20*500000 = $16000000
Rise in price using the value of the basket = (16000000-10000000)/ 10000000 = 60%
