Suppose that GDP is $50 million in 2015 but falls to $48 million in 2016, and that no changes in personal consumption expenditures, gross private domestic investment, and government spending are recorded. What must have happened to net exports to cause this change

Solution and Explanation:

GDP is calculated as follows:

Y = C + G + I + NX

where

C = Consumption

G = Government Expenditure

I = Investment

NX = Net Exports

It is mentioned that in 2015, GDP was 50 million and in 2016, it was 48 million without any change in the factors except NX. It means the net exports that is the difference between export and the import of the country has changed and it has fallen by 2 million.
