The purpose of a production possibilities frontier (PPF) graph is to project rates of currency exchanges given political situations.

The production possibility frontier (PPF) shows the maximum possible output combinations of two goods or services an economy can achieve when all resources are fully and efficiently employed. Labor, capital and technology, among other factors, will affect the resources available, which will dictate where the production possibility frontier lies. The PPF is also known as the production possibility curve or the transformation curve.
