Q.5 What are the characteristics of PPC?
Ans: Production Possibility Curve has two basic properties: -
(1) It slopes downwards.
Production possibility curve slopes downwards from left to right. It is because in a situation of full employment of the resources  production of one good can be increased by decreasing the production of other good only. More of one good will means less of the other. So it has  downward slope.

(2) It is concave to the origin.
Production Possibility Curve is concave to the origin which shows the operation of the law of increasing marginal opportunity cost. Opportunity cost of producing cloth is the quantity of wheat, which may be sacrificed. As the shifting of resources is done from one good to another good the rate of sacrifice increases and it leads to the fact that PPC is concave to the origin
