Answer: 0
Explanation:
Firstly, we will calculate the nominal value in 2015 which will be:
= $500 x 1 million
= $500 million
The nominal value in 2016 will be:
= $1000 x 1 million
= $1 billion
Real GDP will be the price of the base year multiplied by the quantity of the current year which will be:
= $500 million x 1 million sets
= $500 million
Therefore, the increase in real GDP is zero.
