Assume a small nation has the following statistics: its consumption expenditure is $15 million, investment is $2 million, government purchases of goods and services is $1 million, exports of goods and services to foreigners is $1 million, and imports

of goods and services from foreigners is $1.5 million. Calculate this nation's GDP.

The nation's GDP equals the sum of consumption expenditure, investment, government purchases of goods and services, and net exports of goods and services, where net exports of goods and services equals of goods and services exports minus imports of goods and services. So, GDP = $15 million + $2 million + $1 million + $1 million - $1.5 million = $17.5 million.
