Question : Production Possibility Curve (PPC) is concave shaped because
Option 1: Marginal Rate of Transformation (MRT) is increasing.
Option 2: More of one good can be produced only by taking resources away from the production of another good.
Option 3: Both 1 and 2
Option 4: None of the above
Correct Answer: Marginal Rate of Transformation (MRT) is increasing.
Solution : Production Possibility Curve is concave to the origin because Marginal Rate of Transformation (MRT) is increasing. Hence, the correct option is 1.
