1.60
Nominal GDP:
Y1: 50*1.00+100*0.80=130
Y2: 80*1.25+120*1.60=292
Suppose: choose year 1 as base year
Use the price of base year and the quantity of current year
Real GDP:
Y1: 50*1.00+100*0.80=130
Y2: 80*1.00+120*0.80=176
GDP deflator:
Y1: 130/130 *100 = 100
Y2: 292/176 *100 = 165.9091
Price change: (165.9091-100)/100=65.91% = inflation rate
The chain-weight method
2.
