Question

4) A point that lies outside of a PPF is: 1-Inefficient 2-Unattainable 3-Attainable 4-Attainable and inefficient?

Answer 1

2. Unattainable.

Any point outside the PPF curve is considered to be impossible because it represents a mix of commodities that will take more resources to produce than can be obtained because without trade with an external producer It is impossible for an economy to produce outside its PPF. The PPF can change, however, with changes in resources or technology. Additional resources and improvements in technology push the PPF further away from the origin. A loss of resources moves the PPF toward the origin.
