Why is Production Possibilities Curve concave? Explain |
Answer» Solution : (i) PPC is concave because of increasing marginal opportunity cost (MOC). (ii) The behavior of the MOC is based on the assumption that all resources are not equally EFFICIENT in production of all goods. (iii) Rise in opportunity cost occurs when factors (rsources) which are specialized or more adopted for PRODUCTIONOF a PIECE of particular good (say, tanks), is TRANSFERRED to the production of another good (say, wheat) for which they are less productive orless specialized. (IV) Thus, transfer of resources from more productive to less productive uses indirectlymeans fall in their productivity, with the result more of such resources are needed to produce an additional unit of the other commodity. Thus marginal opportunity cost goes on increasing making the PP curve concave in shape. |
