Answer 1

Solution:

a.). i.). Nominal GDP: Current year prices $\times$ current year quantities:

2011: (1 $\times$200) + (2 $\times$50) = 100 + 100 = 200

2012: (1 $\times$200) + (2 $\times$100) = 200 + 200 = 400

2013: (2 $\times$200) + (4 $\times$100) = 400 + 400 = 800

 

ii). Real GDP (Base year 2011): Current base year prices $\times$ current year quantities:

2011: (1 $\times$200) + (2 $\times$50) = 100 + 100 = 200

2012: (1 $\times$200) + (2 $\times$100) = 200 + 200 = 400

2013: (1 $\times$200) + (2 $\times$100) = 200 + 200 = 400

 

iii.). GDP Deflator: $\frac{Nominal\;GDP}{Real\; GDP} \times100 = 100$

2011: $\frac{200}{200} \times100 = 100$

2012: $\frac{400}{400} \times100 = 100$

2013: $\frac{800}{400} \times100 = 200$

b.) i.). Percentage change in Nominal GDP: $\frac{Current \;year\; Nominal\;GDP -previous \;year\;Nominal\;GDP }{previous \;year \;Nominal\;GDP} \times100$

2012: $(\frac{400 - 200}{200}) \times 100 = 100\%$

2013: $(\frac{800 - 400}{400}) \times 100 = 100\%$

ii.). Percentage change in Real GDP: $\frac{Current \;year\; Real\;GDP -previous \;year\;Real\;GDP }{previous \;year \;Real\;GDP} \times100$

2012: $(\frac{400 - 200}{200}) \times 100 = 100\%$

2013: $(\frac{400 - 400}{400}) \times 100 = 0\%$

 

iii.). Percentage change in GDP Deflator: $\frac{Current \;year\;GDP \;Deflator -previous \;year\;GDP\;Deflator }{previous \;year\;GDP\;Deflator} \times100$

2012: $(\frac{100 - 100}{100}) \times 100 = 0\%$

2013: $(\frac{200 - 100}{100}) \times 100 = 100\%$
