Why Is Ppf Concave

The shape of a PPF is commonly drawn as concave to the origin to represent increasing opportunity cost with increased output of a good. Thus, MRT increases in absolute size as one moves from the top left of the PPF to the bottom right of the PPF.

Why is a PPF curve concave?

In any society, people have to deal with limited resources by comparing their opportunity costs. … Most of the PPF curves are concave due to the inadaptability of the resources. The law of increasing opportunity cost states: as the production of one good rises, the opportunity cost of producing that good increases.

Why does PPC slope downward?
