The Connection Between Sources and Uses and the PPC Curve
Here are a few basic points:
The sources and uses report presents the money value of GDP on one side, and the uses of GDP on the other side. In contrast, the PPC curve presents GDP and its uses in terms of quantities of goods, such as units of production.
As stated previously:
In a country without imports, GDP represents the sum of the finished goods produced.
In a country with imports, GDP represents the sum of the finished goods produced, minus total imports.
